Embodiment Construction

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] as attached Figure 1-10 As shown, it is a preferred embodiment of a compound core-pulling mechanism provided by the present invention, including a fixed mold part 10, a dial block 20, a first t-shaped slider 70, a second t-shaped slider 50, a first hydraulic pressure Cylinder 101 and the second hydraulic cylinder 30.

[0035] A compound core-pulling mechanism of this embodiment connects the first forming core-pulling part 40, the second forming core-pulling part 80 and the third forming core-pulling part 60 in the mold, and for the first forming core-pulling parts in three different directions Core member 40, the second molded core-pulling member 80 and the third molded core-pulling member 60 to complete the core-pulling, wherein the first t-shaped slider 70 is connected to one end of the second molded core-pulling member 80, and the sec...

Abstract

The invention relates to a composite core-pulling mechanism, which connects the first molding core-pulling part, the second molding core-pulling part and the third molding core-pulling part in the mold, including a fixed mold part, a shifting block, a first slider, a second The slider, the first hydraulic cylinder and the second hydraulic cylinder push the dial to slide in the sliding groove through the first hydraulic cylinder, and drive the first slider and the second slider to guide in the first guide groove and the second guide groove respectively. The bottom moves upward along the side chute to complete the core pulling of the second core pulling block and the third core pulling block, and the first core pulling block is pulled through the second hydraulic cylinder, which solves the need for three different core pulling blocks at the same position. The core-pulling part of the fixed mold in one direction has a simple structure, is convenient to manufacture, and has a reliable mechanism, which improves the production efficiency of multi-directional composite core-pulling of plastic moulds.

Description

technical field [0001] The invention relates to a core-pulling mechanism, in particular to a composite core-pulling mechanism. Background technique [0002] At present, there are mainly methods for oblique core-pulling of plastic mold fixed molds: one is to drive the slider to pull the core through the inclined guide column; the other is to drive the oblique core to open and close the mold through the inclined guide chute to realize the core-pulling effect. ; Although these two methods can achieve core pulling in structure, they are always single core pulling. When encountering some plastic products with special structures that require 2-3 core pulling in the same place at the same time, it will not be possible to achieve, and then rework to Modify the product structure, so as to realize the structural requirements of some products. The third is to make the oblique core of the fixed mold part into an insert, and take it out manually after the mold is opened. This will incre...
