Description
Technical Field
[0001] This utility model relates to the field of injection mold technology, and in particular to a router injection mold structure with high-efficiency glue injection inside the slider. Background Technology
[0002] Injection molds are molds used for injection molding. They are mainly used to heat and melt plastic particles and inject them into the mold. After cooling, they form plastic products of the required shape and size. Injection molds play an important role in industrial production and are widely used in automobiles, home appliances, electronic communications, daily necessities and other fields. Router injection molds are specifically used to produce router shells. In the process of manufacturing router shells, in order to avoid problems such as fogging, impact marks and shrinkage dents on the outer surface, the injection molding method of the slider inside is usually used.
[0003] Common router injection mold structures with efficient internal injection of the slider are relatively complex and usually require the use of locating pins. When the moving mold and the fixed mold are closed, the locating pins need to pass through the matching circular grooves to push the slider assembly for injection. This places high precision requirements on the locating pins, increases the difficulty of mold processing, and is not practical enough. Therefore, we propose a router injection mold structure with efficient internal injection of the slider. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies. Common router injection molds with efficient internal injection of glue into the slider have complex structures and usually require the use of locating posts.

[0012] The technical effect of the further scheme is that the matching of the plug and the plug groove can prevent displacement during the clamping process of the upper die and the lower die, and improve the use stability.
[0013] As the preferred scheme of the utility model, the inside of the groove is provided with a limiting slot symmetrically near the left and right sides, the limiting slot is slidably connected with a limiting block, and the limiting block is welded with the fixed block.
[0014] The technical effect of the further scheme is that the welding of the limiting block and the fixed block can limit the sliding of the fixed block, prevent the displacement or misplacement of the fixed block, and improve the use stability.
[0015] As the preferred scheme of the utility model, the fixed block is curved near the front and top end, and the push block abuts against the fixed block.
[0016] The technical effect of the further scheme is that during the clamping process, the push block can push the fixed block to the back along the curved surface of the fixed block, so that the sliding block enters the forming groove, and the injection channel and the feeding channel are overlapped.
