Remote control mold manufacturers: some knowledge of injection mold design
Remote control mold manufacturers: some relevant knowledge of injection mold design. In the design of injection mold, the design of gate and runner is involved. If you want to do this design well, you need to know a lot. Suzhou Gurite will give you a detailed introduction: select the appropriate gate position, design the cross gate, submerged gate, point gate, etc. Below we remote control mold manufacturers will introduce the design of the gate and runner for you in detail.

Suzhou Gurite will give you a detailed introduction: select the appropriate gate position, design the cross gate, submerged gate, point gate, etc. Below we remote control mold manufacturers will introduce the design of the gate and runner for you in detail.
1. Select gate position. The selection principle is to ensure the integrity of mold filling, facilitate exhaust, reduce the influence of molecular orientation and the number of weld lines, which is an important part of injection mold design, and pay attention to reduce the influence of weld lines.
2. Flat gate refers to the gate with the gate position on the main parting surface. According to the different shape of the gate, there are fan gate, rectangular gate and flat gate. In order to make the mouth material easy to fall off on the product, the flat door can be designed as a slope. For some transparent products, fan gates can be used. After injection molding, cutting with a metal mold can get a more beautiful product.
3. Mold. This is a commonly used door. When the mold is opened, the nozzle is forced to peel off, which is convenient for automated production. If it is brittle plastic, it is not suitable for diving. It should be noted that the front end of the gate should be machined into a truncated cone shape.
4. Point to the gate. This means that the way the water enters is perpendicular to the top surface of the product. At the same time, the product and nozzle material should be taken out from different parting surfaces. If it is brittle plastic, it is not suitable to use small nozzles.
In the design of injection mold, the design of gate and runner can refer to the above method. The shape and size of the wheel can be designed as a trapezoid, a circle, a rectangle or a semicircle, etc. They all have their own characteristics and scope of application, you can choose the right shape and size according to your needs.
So what are the problems caused by improper exhaust design of injection mold?
In the manufacturing process of the injection mold, if the mold is completely closed, the runner and cavity are completely occupied by air. If the air cannot be completely discharged at this time, the molten material will completely fill this part. Therefore, in the exhaust design, a reasonable design is required. If the design is unreasonable, there will be many problems. The following remote control mold manufacturers will give you a detailed introduction to the problems caused by improper exhaust design of injection mold.
1. Poor filling. Due to the airtight resistance in the mold cavity, the flow of the molten material stops and the flow rate slows down, resulting in poor filling. In addition, there will be a large amount of gas in the mold cavity, which will eventually remain in the mold cavity. If there is no combustion, it will also lead to poor filling. This is likely to occur in highly hygroscopic materials. When the preparation is not sufficient, the remote control mold manufacturer reminds everyone to pay attention.
2. Burning. If the filling speed of the molten material in the mold cavity is faster than the discharge speed, the air in the mold cavity will be compressed, which will immediately cause high temperature. This phenomenon is also called thermal compression, high temperature air and molding parts of the contact will burn black.
3. Overflow. Due to the large amount of air and gas in the mold cavity, the flow of molten material is limited, thereby expanding the split surface, resulting in the same effect as expanding the projection area, causing part of the mold surface to float, resulting in overflow, which is particularly easy to occur in thin meat products.
It can be seen that improper exhaust design of injection mold will lead to very serious consequences, not only causing scorch, flash, poor filling, but also causing silver streaks, bubbles, stains, nozzle lines, etc. on the surface. This can also lead to poor molding. Therefore, the injection mold manufacturers in the design, the exhaust design must be reasonable.
