Embodiment 1

[0031] Such as figure 2 , Figure 4 , Figure 5 In the shown embodiment 1, a multi-point straight jacking glue feeding mechanism for an injection mold includes an upper doubler plate 1, a lower doubler plate 12 and a straight jacking glue feeding assembly, and the straight jacking glue feeding assembly includes a straight jacking block 9 and an inclined The top block 14 is provided with a gate runner 901 for realizing the bottom molding of the product on the straight top block 9. The gate runner 901 includes a runner outlet 902 for product injection, and the runner outlet 902 is opened on the straight top. On the upper end surface of the block 9, the upper end surface of the straight top block 9 is always set close to the ground of the injection molded product 16, and one or several flow channel outlets 902 are set, which are set according to the actual situation of the product. In this application, the flow channel Exit 902 sets one. The straight top block 9 is provided w...

Abstract

The invention discloses a multi-point straight ejection glue feeding mechanism of an injection mold. The multi-point straight ejection glue feeding mechanism comprises an upper compound plate and a lower compound plate, and a hot runner plate is arranged on the upper compound plate. The multi-point straight ejection glue feeding mechanism further comprises multiple straight ejection glue feeding assemblies, each straight ejection glue feeding assembly comprises a straight ejection block and an inclined ejection block, a sprue runner used for feeding glue to the bottom of a product is arranged on each straight ejection block, and the inclined ejection blocks are arranged on the straight ejection blocks. According to the multi-point straight ejection glue feeding mechanism for the injection mold, a better weld line is formed, the product attractiveness is improved, the position of the weld line is convenient to control, and the product strength is prevented from being influenced.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a multi-point straight-jack glue feeding mechanism for injection molds. Background technique [0002] Due to the low requirements on the surface of some plastic parts, in order to save costs, they choose to inject glue directly from the side of the product when injecting the product, and then eject and take out the product. However, the disadvantages of this type of structure are: the weld line on the surface of the product is not good-looking, which affects the appearance of the product, and when the position of the weld line is inappropriate, it will also affect the product strength. [0003] For example, "a plastic frame injection mold and its side glue feeding structure" disclosed in the Chinese patent literature, its announcement number CN209851489U, includes a male template, a mold core and four sliders, and the mold core is fixedly installed on the male template. ...
