Method and device thereof for moulding initial billet of high molecular forming object

Abstract

The invention provides a device for moulding an initial billet of a high molecular forming object. The invention has the main technical characteristic that a single initial billet mould chamber used for moulding the initial billet is divided into two or more different spaces, a material injection procedure is sequentially executed to the dissimilar spaces, and the billet body of the multi-zone initial billet having poor density, poor chromatism, poor hardness or a similar state thereof is obtained by the single initial billet mould chamber.

Description

technical field [0001] The present invention relates to polymer processing technology, in particular to a method for molding a preform of a polymer molded object and a molding device thereof. Background technique [0002] According to the known technology, in the invention patent No. 200610083257.3 of China "Multi-region Forming and Processing Method of Polymer Embryo Body", it is disclosed that the multi-region polymer primary embryo body such as double-color, double-density or the like, will be Different color regions or density regions are formed into single-region blocks of the embryo in different embryo mold chambers, and then merged to form a complete double-region embryo body; the specific technical content is due to its The embryo blocks of different regions are molded in different mold chambers. Therefore, the type of mold it relies on is a three-layer mold mold that is stacked up and down, and between the opposite joint end surfaces of each layer of mold Separatel...

[0002] According to the known technology, in the invention patent No. 200610083257.3 of China "Multi-region Forming and Processing Method of Polymer Embryo Body", it is disclosed that the multi-region polymer primary embryo body such as double-color, double-density or the like, will be Different color regions or density regions are formed into single-region blocks of the embryo in different embryo mold chambers, and then merged to form a complete double-region embryo body; the specific technical content is due to its The embryo blocks of different regions are molded in different mold chambers. Therefore, the type of mold it relies on is a three-layer mold mold that is stacked up and down, and between the opposite joint end surfaces of each layer of mold Separately form the required primary embryo single-zone mold chambers. Therefore, even if the conventional technology content can indeed achieve the purpose and effect of providing double-zone primary embryo embryo bodies, its industrial utilization is still limited to the three-zone mold chamber. Specific processes for layer molds

[0003] And the Chinese No. 200710087299.9 "reducing the polymer blank material filling method of blank material temperature drop" disclosed by the inventor, because its blank molding mechanism does not It is fixed at a specific single position and can be moved along the arrangement direction of the multi-mode station. Therefore, the blank body processing method of the first release is not suitable for such a mobile mold filling procedure.
