Embodiment Construction

[0025] see Figure 3 to Figure 5 As shown, the slider-side core-pulling mechanism of the present invention is applied in a plastic mold, and the plastic mold includes: a male template 100, a female template 110, a male mold core 120, a female mold core 130, and an inclined guide post 140. The block side core pulling mechanism includes:

[0026] A bundle block 200, one end of which is arranged on the above-mentioned mother template 110, and the other end of the bundle block 200 is provided with a T-shaped bump;

[0027] Slider body 300, one end of which is set in the above-mentioned male template 100, one end of the above-mentioned slanted guide post 140 is set in the slider body 300, and the slider body 300 is provided with a corresponding accommodation space for one end of the above-mentioned slanted guide post 140. Among them, a first elastic element 310 is provided between the slider body 300 and the male mold core 120, and the first elastic element 310 is a spring;

Abstract

A slide block side core-pulling mechanism is applied to molds, and comprises a wedge with one end disposed in a female mold plate; a slide block body with one end disposed in a male mold plate, wherein one end of an inclined guide pillar of the mold is disposed in the slide block body; a first slide block insert core connected with the slide block body; a second slide block insert core which passes through the slide block body and the first slide block insert core and has one end movably connected with the wedge; a third slide block insert core which is disposed in the first slide block insert core and is movably connected with the other end of the second slide block insert core. The slide block side core-pulling mechanism of the invention solves the problem of incapability of breaking return for the slide block insert core and a mold core when the mechanism is used for producing products with barbs in a barb direction and without breaking positions.

Description

【Technical field】 [0001] The invention relates to a mold mechanism, in particular to a slider-side core-pulling mechanism. 【Background technique】 [0002] When producing plastic products, sometimes due to the limitation of the structure of plastic products, the product is provided with another barb in the direction of one barb. At this time, if the product has a broken position, please refer to figure 1 As shown, it is necessary to add the break-return entry 1, so when the mold is closed, it can only rely on the break-return insert 1 and the mold core 3 to rely on the break-return, and the product 2 can be demoulded if there is a break position; The product does not have a broken position, see figure 2 As shown, that is, when the slider insert and the mold core 3 cannot be returned by breaking, the product 4 without the breaking position cannot be demoulded, causing troubles in mold design. [0003] In view of this, it is necessary to develop a slider side core-pulling m...
