Problems solved by technology

[0003] Mold processing is a common means of existing mechanical processing. For mold processing, demoulding is one of the important steps. However, for products with horizontal inward recesses on the inner side, the existing slider core-pulling cannot meet the convenience of core-pulling. According to the requirements, the second core-pulling in the middle is required, which leads to more production steps, wastes processing time, reduces the production efficiency of the product, and because the positioning may not be accurate during reset, the processing accuracy of the product is low.

Embodiment Construction

[0011] Such as figure 1 and figure 2 , an internal core-pulling structure, which includes a mold 1, a pin puller 2, and a slider 3. A pin puller groove 4 is longitudinally opened in the middle of the mold 1, and the puller pin 2 is set in the pin puller groove 4. The puller pin 2 includes a puller There are five parts: pin head 5, tail part 6, rear part 7, middle part 8, and front part 9. The diameter of pin pulling head 5 is larger than other parts of pulling pin 2. The diameter of tail part 6 is the same as that of pin pulling groove 4. The diameter of tail part 6 The diameter is greater than the diameter of the rear part 7, the middle part 8 and the front part 9, the rear part 7 leans against the side inner wall of the pin pulling groove 4, and the front part 9 leans against the inner wall of the inner wall against which the rear part 7 leans, and the front part 9 It is connected with the rear part 7 through the middle part 8, and the diameters of the rear part 7 and the ...

Abstract

Mold processing is a conventional means of the existing mechanical processing, demolding is an important step of the mold processing, the existing slide-block core pulling cannot meet the requirement on pulling the core conveniently for a product with a horizontal inward concave on the inner side, secondary core pulling is needed, thus the production procedures are complicated, the processing time is wasted, the production efficiency of the product is lowered, and the processing precision of the product is low due to the incorrect location of the product after the product is restored. In order to solve the problems, the internal core pulling structure comprises a mold, a slide block and an unplugging pin, after the internal core pulling structure is used, when the core pulling is needed, the head of the unplugging pin is unplugged upwards, and the unplugging pin drives the slide block to move leftwards, so that the slide block is separated from the product; when the restoration is needed, the head of the unplugging pin is pressed down, the unplugging pin moves downwards, the slide block is driven to move rightwards, and since the position of the unplugging pin in restoration is fixed, an effect of precise location can be realized.

Description

[0001] Field [0002] The invention relates to the structural technical field of product molds, in particular to an internal core-pulling structure. Background technique [0003] Mold processing is a common means of existing mechanical processing. For mold processing, demoulding is one of the important steps. However, for products with horizontal inward recesses on the inside, the existing slider core-pulling cannot meet the convenience of core-pulling. According to the requirement, the core needs to be pulled twice in the middle, which makes more production steps, wastes processing time, reduces the production efficiency of the product, and due to the possible inaccurate positioning during reset, the processing accuracy of the product is low. Contents of the invention [0004] In order to solve the above-mentioned problems, the present invention proposes an internal core-pulling structure. After using the present invention, the middle core-pulling can be facilitated, and th...
