Problems solved by technology

[0002] During the production process of traditional plastic molds, if the products produced have ribs, grooves or undercuts in the direction of the front mold, etc. When the above abnormal situation occurs, it will lead to the following results: 1. The product stays in the front mold, and the ejection mechanism of the rear mold cannot function
2. The product sticks to the front mold, which is easy to strain the product, resulting in unqualified products, resulting in low yield and increased production costs

[0035] Please refer to figure 1 , figure 2 with image 3 , the embodiment of the present invention provides a fixed mold ejection structure 1, which is used to eject the product from the mold after the product is formed, so as to realize the unloading of the product. Its structure is simple, and the product can be ejected from the direction of the front mold towards the rear mold to prevent the product from sticking to the mold. The ejection movement is stable and reliable, and has strong practicability.

[0036] The ejection structure 1 of the fixed mold includes an ejector pin assembly 2 , a fixed template 3 , a movable template 4 , a buckle 5 , a stopper 6 , an elastic member 7 , a holding member 8 and a limiting member 9 . The fixed template 3 is arranged between the thimble assembly 2 and the movable template 4, and the movable template 4 can be close to or far away from the fixed template 3, so as to realize the action of mold closing or mold opening. The fixed templ...

[0051] Please refer to Figure 7 , the embodiment of the present invention provides an injection mold 27 for producing plastic products. The injection mold 27 includes a fixed mold ejection structure 1 and a movable mold main body 28 . Among them, the basic structure, principle and technical effect of the fixed mold ejection structure 1 are the same as those of the first embodiment. For a brief description, for the parts not mentioned in this embodiment, reference may be made to the corresponding content in the first embodiment.

[0052] In this embodiment, the movable mold body 28 is connected to the movable template 4 by screws, so as to drive the movable template 4 to approach or move away from the fixed template 3, so as to complete mold closing or mold opening.

[0053] The beneficial effect of the injection mold 27 described in the embodiment of the present invention is the same as that of the first embodiment, and will not be repeated here.

Abstract

The invention provides a fixed die ejection structure and an injection molding die, and relates to the technical field of dies. The fixed die ejection structure comprises an ejector pin assembly, a fixed die plate, a movable die plate, a buckling machine, a stopping part, an elastic part and a clamping part, wherein a storing groove is formed in one side of the ejector pin assembly, and the clamping part is connected to the bottom wall of the storing groove through the elastic part; the buckling machine is fixedly mounted on the movable die plate and is clamped to the clamping part; the stopping part is fixedly mounted on the fixed die plate and can be matched with the clamping part when the ejector pin assembly moves to a preset position in order to eject the clamping part into the storing groove after resisting the elasticity of the elastic part. Compared with the prior art, the fixed die ejection structure has the advantages that the clamping part which is clamped to the buckling machine and the stopping part which is matched with the clamping part are provided, and the ejector pin assembly can be driven by the movable die plate to eject out a product in the direction from the fixed die plate to the movable die plate, and thus the product is prevented from being adhered to the die; the ejecting movement is stable and reliable; and the practicability is high.

Description

technical field [0001] The invention relates to the field of mold technology, in particular to a fixed mold ejection structure and an injection mold. Background technique [0002] During the production process of traditional plastic molds, if the products produced have ribs, grooves or undercuts in the direction of the front mold, etc. When the above abnormal situation occurs, it will lead to the following results: 1. The product stays in the front mold, and the ejection mechanism of the rear mold cannot function. 2. The product sticks to the front mold, which is easy to strain the product, resulting in unqualified products, resulting in low yield and increased production costs. Contents of the invention [0003] In view of this, the present invention aims to propose a fixed mold ejection structure, which has a simple structure and can eject the product from the front mold to the rear mold, preventing the product from sticking to the mold, and the ejection movement is sta...
