Double material gradient injection molding device

Abstract

The invention provides a double-material gradual change type injection molding device. The device comprises a vertically-placed mixed feeding channel, wherein a vertical rectangular-plate-shaped cavity is designed in the mixed feeding channel, two single-color feeding boxes arranged side by side left and right are assembled on the upper portion of the mixed feeding channel, a power module is designed at the front part of a middle cavity of the mixed feeding channel, the power module comprises more than ten stirring shafts which horizontally and vertically go deep into a plate-shaped cavity inthe mixed feeding channel, stirring rods extend out of the stirring shafts, the stirring shafts are divided into more than three layers from top to bottom in the plate-shaped cavity of the mixed feeding channel, the stirring shafts between every two adjacent layers are arranged in a staggered manner, and a forming module is designed at the lower part of the mixed feeding channel. The device is mainly used for carrying out injection molding processing on molten substances with different colors, and can be used for integrally processing two plastic substances which have different properties andare not easy to bond.

Description

technical field [0001] The invention relates to the technical field of injection molding of granular plastics, in particular to a double-material gradual injection molding device. Background technique [0002] In the process of plastic processing, plastic granules are often used as raw materials. By melting the granule raw materials, and then injecting the granule raw materials in the molten state into the mold, the plastic is cooled and fixed. Due to the need for injection molding operations, traditional plastic processing Usually, individual colors or mixed plastic materials are used for melt injection molding, so there is usually only one single color in one injection molded product. This greatly limits the color expression of plastic products, and when plastic products require different colors, they often need to be completed by splicing different products, which not only makes the processing more complicated, but also has obvious color differences at different connectio...

[0002] In the process of plastic processing, plastic granules are often used as raw materials. By melting the granule raw materials, and then injecting the granule raw materials in the molten state into the mold, the plastic is cooled and fixed. Due to the need for injection molding operations, traditional plastic processing Usually, individual colors or mixed plastic materials are used for melt injection molding, so there is usually only one single color in one injection molded product

This greatly limits the color expression of plastic products, and when plastic products require different colors, they often need to be completed by splicing different products, which not only makes the processing more complicated, but also has obvious color differences at different connection positions of injection molded parts, which affects product aesthetics

In addition, when the product is being injected, the raw materials for injection molding are mixed according to the required ratio before processing. The traditional mixing method is usually to pour the material into the mixing box and then stir it. Not only the mixing effect is poor, At the same time, due to the need to stir the raw materials as a whole, the stirring efficiency is low

Therefore, in automatic plastic granule feeding equipment, in order to ensure accurate feeding of mixed plastic granules, quantitative material chambers are usually used for feeding, and each time when different plastic granules are mixed, different feeding chambers need to be changed. Use extremely inconvenient
