Abstract

An injection molding method capable of reducing mold seam traces. When the injection molding mold is first used to inject resin melt adhesive thereto, the resin melt adhesive is regulated such that it may be injected through one of the plural adhesive feeding gates of injection molding mold, for feeding and injecting into the cavity of the injection molding mold. During the process of feeding the resin melt adhesive into cavity, the sequence and timing of injecting the resin melt adhesive through the other adhesive feeding gates is controlled automatically such that the resin melt adhesive that is injected into the cavity under different sequence and timing may merge into single stream during the process of feeding the resin melt adhesive into cavity, to avoid leading edges of two or more streams of resin melt adhesive from colliding into each other, so as to effectively reduce and eliminate the poor joint of resin melt adhesive and to ensure that the plastic products as obtained will have a bright surface and be almost free of melt adhesive mold seam traces.

Description of the invention: [Technical field to which the invention pertains] The present invention relates to a Lai 彡 杂 · 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢 谢Single-flow injection molding method to reduce the line marks. [Prior Art] In the injection molding technology, when the molded product is shot at a multi-point transfer, the surface of the finished plastic product usually has streaky traces of the melt-bonding line, and the molded article which is particularly important for the appearance is naturally taboo. Greatly affect the surface quality of plastic finished products. In the case of the mold in the field of Figure la, when the mold is turned over by the township, the molds for the molding die 1 will be placed on the top of the tree. Point scale wash 13 Therefore, in the process of injection molding to fill the smelting resin, as shown in the figure, the smelted resin is almost simultaneously filled into the mold from the sprue 13 of each runner 12 of the lasing 11 In the mold cavity, the cavity of the cavity to be filled is filled with molten fat and cooled and solidified, and the finished plastic product A can be obtained. In the process of filling the molten resin, Renqi’s plastic filling technology often causes two or more shares as shown in the figure, because of the multi-point glue flooding 13 while filling and filling the resin. The pre-fine bonding of the resin melt can not form a single-flow filling. If the temperature of the two or more strands of rubber is too low, the fluidity of the melt is poor, or the difference in the properties of the melt is too large, the bonding effect of Na Often not ideal, a strip-shaped bond line or joint region formed by the collision of the leading edge of two or more scales is formed. Therefore, the shortcoming of the multi-point filling technique is that the surface of the finished plastic product A is likely to have a stripe-like melt bond line trace c, which in turn affects the surface quality of the plastic finished product A. In the liquid aa, the sulfur content of II is displayed. In order to conceal the traces of the joint line on the surface of the pre-manufactured product, the cost of the sheet must be increased to make the surface of the finished frame into a bitten surface, or by polishing or painting again. Secondary processing is used to improve the surface quality of the finished front frame. 5 1275476 Therefore, 'for plastic products that do not consider surface biting or secondary processing to improve the surface quality, the eve of the transformation technology' does not solve the special requirements of the surface of the plastic finished product, there must be no bonding wires, dents or The existing problems such as poor gloss. [Summary of the Invention] ^The purpose of the invention is to sell the kind--reducing the joint _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The technique must make the resin squeegee almost simultaneously fill the cavity into the cavity from each of the miscellaneous sputums. ??? First, by controlling the resin, the glue can only be used first from the injection molding die. The 2 turns are like filling the mold hole into the person who shoots the female, and secondly, the paste is filled into the right month of the moon, and the arboreal glue is automatically controlled in the filling process, and the order is changed. And the purpose of not filling the machinery (9), "the filling process of the eight-in-one filling the hat and hiding the job list - the filling of the hegemony" is the front edge of the melt glue, and the 前, 丨, 』, 舣a eve of the moon and the tree 曰, ~% of the injection molded article on the surface of the joint line traces, ^ & In addition to the surface quality of the finished rubber product, compared with the conventional multi-point injection molding technology, the surface f of the finished product can be dispensed with biting or secondary addition. The child is also hand-made and has a plastic-finished product with the mark of the joint. The implementation steps include: a. Shooting the female and female dresses, returning to the finished product; b. retaining the multi-point diverting port of step a Among them, a tender mouth is set to a normal tender mouth; C.
