Problems solved by technology

[0002] In the existing injection molds, the inside of the molding cavity for molding plastic products is generally filled with ejector pins or ejector blocks, so that the products can be pushed out directly after injection molding. This method will leave traces of the ejected parts on the surface of the plastic products

Embodiment Construction

[0019] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] see Figure 1-2 As shown, the above-mentioned non-mark ejection mold includes a first template 1 with a first mold core 2, a second template 3 with a second mold core 4 and used to cooperate with the first template 1 to open and close the mold, and can The ejector pin 5 that passes through the second template 3 and the second mold core 4 is movable along the extending direction of its own length. In this embodiment, the first template 1, the first mold core 2, the second mold core 4, and the second template 3 are vertically from top to bottom (see figure 1 as shown, figure 1 The top of the middle is the upper here) arranged in sequence, the ejector pin 5 extends vertically, the upper end of the ejector pin 5 can pass through the second mold core 4 upwards, and the lower end of the ejector pin 5 can pass through the second template 3 d...

Abstract

The invention discloses a traceless ejection mold. The traceless injection mold comprises a first mold plate with a first mold core, a second mold plate with a second mold core, an ejector rod capableof movably penetrating through the second mold plate and the second mold core in the length extending direction of the ejector rod, a guide column fixedly arranged in the first mold plate, a slidingblock slidingly arranged on the second mold plate in the direction close to or away from the second mold core and arranged on the guide column in a sleeving manner, and an insert arranged on the sliding block and used for cooperating with the first mold core and the second mold core to form a forming cavity; the sliding block is arranged between the first mold plate and the second mold plate, andthe insert comprises a first body abutting against the side face of a formed part and a second body connected to the first body and located between the formed part and the ejector rod; and during moldopening, the guide column is used for driving the sliding block to slide away from the forming cavity, so that the second body is pulled away from the formed part and the ejector rod. According to the traceless ejection mold, ejection traces cannot be formed on the surface of the formed part, and the attractiveness of a product is guaranteed.

Description

technical field [0001] The invention relates to a traceless ejection mold. Background technique [0002] In the existing injection molds, the inside of the molding cavity for molding plastic products is generally filled with ejector pins or ejector blocks, so that the products can be pushed out directly after injection molding. This method will leave traces of the ejected parts on the surface of the plastic products . For some products with high appearance requirements, no non-structural traces are allowed on the surface of the product. Contents of the invention [0003] The object of the present invention is to provide a traceless ejection mold, which will not form ejection marks on the surface of the molded part and ensure the appearance of the product. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A traceless ejection mold, comprising a first template with a first mold core, a second template with a ...
