Embodiment Construction

[0019] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0020] Such as Figure 2-3 As shown, a core-pulling structure of a mold includes at least one core-pulling insert 10, and also includes a pressing plate 20 and a shifting block 30; wherein, each core-pulling insert 10 is connected to the pressing plate 20; the shifting block 30 can be positioned relative to the mold The male mold moves; one end surface of the shifting block 30 is provided with an inclined shifting block groove 31;

[0021] Specifically, the pressing plate 20 includes an upper pressing plate 21 and a lower pressing plate 22 connected up and down; one end of each core-pulling insert 10 is connected between the upper pressing plate 21 and the lower pressing plate 22 . By fixing the core-pulling inserts 10 on the pressing plate 20, it can be ensured that the core-pulling inserts 10 mov...

Abstract

The invention relates to the technical field of moulds, and specifically discloses a core-pulling structure of a mold, which includes at least one core-pulling insert, and also includes a pressing plate and a shifting block; wherein, each core-pulling insert is connected to the pressing plate; The male mold of the mold moves; one end surface of the shifting block is provided with an inclined shifting block groove; the pressure plate is slidingly matched with the shifting block groove, and is driven by the shifting block to move along the core-pulling direction of the core-pulling insert. The core-pulling structure can improve the stuckness of the core-pulling insert and improve the running stability of the core-pulling insert.

Description

【Technical field】 [0001] The invention relates to the technical field of molds, in particular to a core-pulling structure of a mold. 【Background technique】 [0002] The injection mold is usually equipped with a core-pulling structure, through which the molding part that hinders the ejection of the injection molded part can be separated from the injection molded part before the mold opening action is completed. [0003] Such as figure 1 As shown, the existing core-pulling structure includes a plurality of core-pulling inserts 10' and a slider 20', and a plurality of T-shaped chute 21' is opened on the slider 20', and one end of each core-pulling insert 10' is divided into The part is slidingly matched with the corresponding T-shaped chute 21'. When opening the mold, the core-pulling insert 10' is driven to slide along the T-shaped chute 21' by driving the slider 20' to move, thereby realizing the core-pulling action. [0004] However, the existing core-pulling structure ha...
