Heat mould feeding method of compound region polymer embryonic plant

Abstract

The invention provides a hot die feeding method of complex domain polymer idiosome. The die chamber inside the die is separated into individual multiple chambers disconnected with each outher in proper area by separation part. The different polymer raw materials are individually injected into the corresponding independent chamber. After feeding, the said separation part is removed or the separation part combines with raw materials to make idiosome, furthermore the obtained idiosome is in form of complex domain to satisfy the industrial needs.

Description

technical field [0001] The invention relates to the polymer molding processing technology, in particular to a thermal mold injection method for a multiple-zone polymer embryo body. technical background [0002] The known thermal injection molding processing technology is implemented by keeping the mold at a temperature slightly lower than the polymerization or crosslinking reaction temperature of the polymer, so that after the injection of the raw material is completed, the time required for heating up to the reaction temperature can be shortened. time, thereby improving the efficiency of manufacturing, although these technologies have their effects, but relatively, they also have shortcomings that cannot be overcome by conventional technologies.

AI Technical Summary

Problems solved by technology

[0002] The known thermal injection molding processing technology is implemented by keeping the mold at a temperature slightly lower than the polymerization or crosslinking reaction temperature of the polymer, so that after the injection of the raw material is completed, the time required to raise the temperature to the reaction temperature can be shortened. time, thereby improving the efficiency of manufacturing, although these technologies have their effects, but relatively, they also have deficiencies that cannot be overcome by conventional technologies

[0003] In the conventional technology disclosed above, since the mold is maintained at a relatively high temperature, the molten polymer raw material injected from the injection device still has considerable fluidity in the inner cavity of the mold. There is no hindrance to the technical field of injecting only single-color raw materials into the mold chamber to make the embryo body, but when the embryo body to be prepared is in the form of double-color, multi-color, etc. or double-density, multi-density, etc. , its implementation is clearly limited to the impossibility of

[0004] In detail, when a polymer material is injected out of the mold chamber with a single injection nozzle, another polymer material that has been filled in advance will make the injection The high polymer raw material will move the surface of the filled polymer raw material. In this way, the interface between the two raw materials will lose the obvious separation, and the uneven state of color mixing and color shift will appear under the complex color. The lower density also makes the design of complex density lose its original expected effect;

[0005] When injecting two different polymer materials into the cavity of the mold with double injection nozzles, the conventional technology lacks the technology to control the flow of the two materials. Under the condition of control, arbitrary mixing with each other, lack of application conditions for industrial implementation, it is impossible to produce polymer embryos with the required multi-color, multi-density and other multi-region forms
