Guangzhou Haoshun Mould Co., Ltd. is an enterprise approved and registered by the relevant state departments. It has more than ten years of experience in the design and production of plastic molds. So what should we pay attention to when designing molds? 在设计时需注意的事项及它的作用？ Today we will talk about the matters needing attention in the design of Guangzhou mold design and its role?
The role of the inclined top in the mold design:
When there is an inverted buckle in the product, the burr generated by the inclined top is not high. In order to reduce the mold cost and simplify the mold structure, we can make an inclined top instead of the core pulling form.
The main function of the oblique ejection core pulling mechanism is to pull the core, and it can also play the role of ejection. Where there is an oblique ejection core, there is generally no need to place a thimble nearby.
1. The inclined top must have a straight position (usually 5 mm), which is used as the glue sealing position and the processing reference number.
2. The core pulling distance is generally larger than the undercut amount by 2 mm. For large products, the core drawing distance should be calculated according to the size (size * shrinkage rate + undercut amount + 1 mm).
3. The angle of the inclined top is generally 3-15 °. According to the situation, it should be designed as small as possible. The smaller the designed angle, the more space can be saved and the ejection will be smoother.
4. Do not interfere with other parts or products when making a decision.
5. The beveled roof should have sufficient strength. Commonly used are 8mm, 10mm and 12mm.
