Feeding device and feeding method based on liquid silica gel injection molding machine

Abstract

The invention relates to the technical field of injection molding, and provides a feeding device based on a liquid silica gel injection molding machine. The feeding device comprises a partition plate, the left side of the partition plate is fixedly connected with a female die, the right side of the partition plate is fixedly connected with a feeding pipe, the inner wall of the feeding pipe is movably connected with a screw rod, the right end of the screw rod is movably connected with a rotating disc, the outer wall of the rotating disc is movably connected with a rotating rod, and the outer wall of the rotating rod is slidably connected with a sliding block. According to the feeding device based on the liquid silica gel injection molding machine and a feeding method, a linkage rod is driven to move while the rotating disc rotates, a fixed rail and a guide rod play a role in controlling a push plate to move horizontally, the push plate pushes a push block through a connecting rod, the push block periodically compresses an inclined block, so that a blind nut is continuously lifted and pressed downwards; and the blind nut ascends to suck liquid silica gel through pressure, a first gate is closed, a second gate is opened, then the blind nut is pressed downwards to open the first gate and close the second gate, the flowing amount of the liquid silica gel is controlled, and bubbles caused by vacancy are avoided.

Description

technical field [0001] The invention relates to the technical field of injection molding, in particular to a feeding device and a feeding method based on a liquid silicone injection molding machine. Background technique [0002] Injection molding machine is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products with plastic molding molds. With the development of the times, the types of injection molding raw materials are gradually increasing, and the types of production products are also gradually increasing. Injection molding products have become people's daily life. Indispensable and important part of life. [0003] In the existing technology, the feeding speed of the screw rod determines the quality of the injection molded product. If the feeding speed is too fast, tiny gels will appear in the injection molded product, which not only affects the aesthetics of the product, but also reduces the quality of the i...

Problems solved by technology

[0003] In the existing technology, the feeding speed of the screw rod determines the quality of the injection molded product. If the feeding speed is too fast, tiny gels will appear in the injection molded product, which not only affects the aesthetics of the product, but also reduces the quality of the injection molded product, and the delivery volume determines the liquid Whether there are gaps between the silicone, the gaps will cause bubbles and missing parts in the injection molding products
