Camera bracket injection molding process and injection molding machine using the injection molding process

Abstract

The invention discloses a camera bracket injection moulding process and an injection molding machine adopting the same. The process includes the following steps: a step 3 of gel-like material injection, namely a step of injecting melted native plastic particles into a die; a step 4 of cooling, namely a step of cooling at the first second to the second second; a step 5 of die opening, namely a stepof opening the die at the fourth second to the sixth second; a step 6 of demoulding and unloading, namely a step of clamping a channel through a mechanical hand and sucking and unloading the camera bracket through negative pressure; a step 7 of carrying the channel to a chopping device through the mechanical hand; a step 8 of chopping materials to form regenerated plastic particles and adding a cross-linking agent; and a step 9 of putting the regenerated plastic particles and the native plastic particles in a loading hopper of the injection molding machine in a ratio of 1:9. Waste of 10%-20%of a material can be avoided by putting the channel dealt as waste back into production as a raw material.

Description

technical field [0001] The invention relates to the field of injection molding, in particular to an injection molding process for a camera bracket and an injection molding machine using the injection molding process. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die casting method. Injection molding machine is the main molding equipment for making thermoplastics or thermosetting materials into various shapes of plastic products using plastic molding molds. Injection molding is realized through injection molding machines and molds. [0003] In the prior art, the mobile phone camera bracket is usually produced by traditional injection molding process. In order to improve production efficiency, it is usually processed by molding multiple plastic parts at one time....

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the mobile phone camera bracket is usually produced by traditional injection molding process. In order to improve production efficiency, it is usually processed by molding multiple plastic parts at one time. However, this processing method needs to be erected between adjacent plastic parts. There are cold runners for the flow of molten materials, the volume of plastic parts is small, and the cold runners must ensure the injection pressure and injection speed, so the diameter of the cold runners is generally designed to be large, and the injection molding through the cold runners will It will cause 10%-20% waste of raw materials

[0004] In the prior art, the invention patent with the publication number "CN102785325A" discloses an ABS material injection molding process for infusion sets, which includes the following steps, S1, melting glue; S2, mold closing; S3, injecting glue; S4, cooling; S5 , mold opening; S6, demoulding process, which uses a hot runner plate instead of the runner in the traditional process to solve the above problems, but the market price of a hot runner plate is around 200,000 to 300,000. The cost of each plastic part is greatly increased; at the same time, for the small camera bracket, each bracket has a different structure adjustment, so the injection position of each bracket is different, and different plastic parts need to be purchased. The hot runner plate further increases the production cost of plastic parts
