Three hours later, Ji Rong pushed hard but couldn't open Wenyu's door. In helplessness, she had to shout loudly: "Xiaoyu, come out for lunch quickly."

Her shouts woke Wenyu up, and he felt a little hungry at this time.

Although I feel too much helpless, my work has to continue.

After dinner, he installed a laptop in his dormitory. After turning on the computer, he hurriedly converted the bridge drawings to PDF format.

Since the SolidWorks design software was still in the two-dimensional drawing stage at this time, there was no analysis guide and many deep-level design functions. Therefore, Wenyu began to revise and upgrade the 92 version of SolidWorks software according to the 21st century software function parameter equations.

The bridge design language has basically been completed, so you just need to copy the drawings and print them out to start production. However, copying the file has become a problem.

In the 1990s, the Internet was not popular yet, including mobile hard drives, USB drives, and some transmission software. Even the biggest function of QQ is just chatting and making friends.

Burning files with blank CDs is one of the best choices for current language.

He thought of the agreement with Li Daopai tomorrow. Perhaps Boss Li has some advanced imported things to use, or he has imported goods with copy documents!

After he clarified the bridge drawings, he was worried about Wen Qian, who was directly related to the success or failure of Wen Yu's competition with Yu Heng.

Wenyu opened the Great Wall brand electric fan, and the wind blowing from the wind was still hot on his face. He calmed down a little and began to enter the conception stage of the ballpoint pen set mold design.

He recalled the shape of the 21st century ballpoint pen, the comfort of holding the pen, and the materials.

He needed information inquiries before mold design, but the information was very small in the 1990s, so he had to go to the nearest Xinhua Bookstore to peek at the bookstore. Wen Yu's favorite thing to do.

Originally, he planned to return Cao Xiaowen's 1,000 yuan. No matter whether her family has money or not, Wenyu felt uneasy to take the money.

Perhaps because of the noon weather, he did not plan to go to Xinhua Bookstore to check information, so he preferred the thinking of mold design. Based on his life experience and technical experience, he decided that the ballpoint pen cover mold consists of a push-and-fold type and a center core pull-out principle.

Plastic molds are generally composed of upper mold, lower mold, mold meat, shovel base, rowing position, jig, thimble, shaft sleeve and other components.

The ballpoint pen shell is made of a pen body and a pen cap. The conventional ballpoint pen mold design text is very clear. After all, he was an industrial design engineer in his previous life and was confident about this set of molds.

He selected the mold material skd11 and made it into a ballpoint pen in the mold meat, half of the upper and lower molds, divided into two from the center of the cylinder, and the two sides were closed to form the outer shape of the pen sleeve.

In this way, the pen sleeve is solid, so the text considers that it is not allowed to exceed the left and right positions, and a push-pull refill rod must be added, which is driven by the cylinder.

When the mold stands on the injection molding machine, combined and heats, the glue flows into the mold along the runner. After hot melt injection molding, the upper and lower molds will be separated, and the row positions will be automatically pulled out by the shovel base when the mold is separated, that is, the cylinder will pull out the center of the ballpoint pen sleeve at the same time.

In this way, the mechanical arm, automation and CNC industries were still in its infancy in the 1990s, and most injection molding factories had to choose manual pick-up products. Because it was manual, accidents of scalding workers often occurred.

The simple design principles of the mold have been sorted out. He thought that Boss Li is good to him. For the safety of the workers and to repay Boss Li for his gift, he felt that it was reasonable to design a set of robotic arms for Boss Li.

The mold of the ballpoint pen cover is basically formed in Wenyu's mind. The design of the pen cap and pen cover is slightly different, but the shapes of the molded meat are different.

When Wenyu completed the ballpoint pen set mold design, it was already dusk. A breeze blew, and Wenyu's heart was paused.

My father didn’t know where he went? Will he go to work on Monday?

He knew that he could not find Wen Gan, but fortunately he completed the task of the competition with Yuheng earlier, and maybe he could really get paid and have money to treat Wen Gan.

The ballpoint pen cover mold is currently short of the shrinkage rate budget for plastic materials.

In the 1990s, mobile phones were only big bricks, with a retail price of more than 10,000 yuan, which was the symbol and symbol of the households of 10,000 yuan at that time.

Now Wenyu needs to communicate with Boss Li about the material selection of the ballpoint pen cover. As long as you know the material, you can calculate the shrinkage rate during injection molding.

There is a lack of something, that is, mobile phones, and unit phones are only connected to the regional network.

No matter how Wenyu said, he had to go to Wanda Enterprise in person, so he began to prepare a meeting gift to Boss Li and a drawing for making a mechanical arm.

The robotic arm is a very simple robotic arm. For this era when automation equipment was first discovered, it must be a huge surprise for Boss Li.

Although there are limitations on functional things in mechanical design drawing software now, it is not difficult for languages ​​from 29 years later.

Automatic transmission systems are inseparable from electronic components, even servo motors, cylinders, PRC controllers, solenoid valves, power switches, various electronic wires, various terminals, inverters, etc., there are very few domestic products in the current market, and most of them need to be imported.

For now, when eating, he still depends on his parents' words, the robot arm can only think about it. He gave up the meeting for Boss Li and decided to talk about it tomorrow after communicating with Boss Li.

...

Today, the sun shines brightly and the autumn wind is bleak. A coolness blows Wenyu's yearning for the future. He knows that there is a group of lottery tickets that are still fresh in the near future. He hopes to use it to treat his father and to fill his regrets in his previous life.

Wenyu had breakfast and went out, but Ji Rong did not ask him to look for Wengan.

He knew that Wen Gan was impossible for him to find him easily, and he only hoped to see him at work tomorrow.

Wenyu went to Xinhua Bookstore and the electronics market until the time he made an appointment with the sissy Li Daopei appeared at the door of Wanda Enterprise.

To be honest, Wenyu wants to do a lot of things now, but he just has no money, which is a fatal problem. He wants to use Boss Li to make Yongfeng No. 1 Machine Tool Factory survive.

Li Daopei, holding a parasol, shouted to Wenyu: "Ouch! Brother Yu, why don't you hold an umbrella if it's so hot! Hahaha, it's good that people have an umbrella, you have a big head, hehe."

"Shaopi, take me to see your second uncle."

"What's the hurry! Maybe he's not in the company! I'll call him."

Wenyu looked at the sissy Li Daopai in surprise and thought: In this era, most of the big brothers are short of each movie, more than 10,000 yuan each. Even if he has a brick, why didn’t he take it out in Yongfeng? Is he just to hide his identity?

I saw that what Li Daopai took out was the Lokia tablet nine-key mobile phone!

Could it be that Lokia had developed a tablet phone at this time?

Wen Yu's hesitant eyes puzzled Li Daopei: "What's wrong with Brother Yu? I'm a newly developed mobile phone from Lokia that my second uncle spent more than 20,000 yuan abroad. It's a test machine that has not been launched yet. However, there is a problem with this mobile phone. I heard that anyone who can solve the problem will have the first agency in China."
