As shown in fig. 3, the embodiment of the present invention provides a mold slide structure, which includes a slide insert group 1 and a slide seat 2 movably connected to each other; the slide insert group 1 comprises a forming part 11 and a clamping part 12 which are oppositely arranged, and the forming part 11 can be embedded into the die cavity 4 of the die core 3 and matched with the die core 3 to form a forming space of a product; the slide seat 2 is located at an end of the slide insert group 1 opposite to the mold core 3, and the slide seat 2 includes a slide body 21 and a locking member 22 movably mounted on the slide body 21. In the slide mold closing process, the fastener 22 is fastened with the fastener portion 12 along the mold closing direction to connect the slide seat 2 and the slide insert group 1. The mold closing direction is the moving direction of the slide base 2, that is, the connecting direction of the slide insert group 1 and the slide base 2. It should be noted here that, because the slide holder 2 can only be slidably connected to the guide structure of the mold, and the movement direction of the slide holder 2 is restricted by the guide structure and can only move in the mold closing or mold releasing direction, when the slide holder 2 and the slide insert group 1 are designed to be integrated, it is not possible to simply place the hardware 71 on the slide insert group 1 fixedly connected to the slide holder 2 and then place the integrated slide structure including the hardware 71 on the mold. In addition, due to the limitation of the curved shape of the hardware 71, the hardware 71 must be placed in the cavity of the hardware 71 on the mold core 3 before the mold is closed.

According to the line position structure of the die with the line position insert group 1 and the line position seat 2 detachably connected, before die assembly, the line position insert group 1 and the line position seat 2 are separated, a hardware piece 71 can be installed in the line position insert group 1 outside the die, and then the line position insert group 1 with the hardware piece 71 installed is placed in a die core 3; in the process of die assembly, the slide seat 2 is buckled with the buckling part 12 on the slide insert group 1 through the buckling piece 22 on the slide seat to realize the connection of the slide seat and the slide insert group; in the demolding process, the slide seat 2 can drive the slide insert group 1 to move outwards together to realize demolding; after the demolding is finished, the slide insert group 1 can be taken out from the slide seat 2 along the direction perpendicular to the mold closing direction, and the disassembly and the assembly are convenient. According to the die slide structure, in the die closing process, no motion friction exists between the hardware 71 and the slide insert group 1, so that the problems of copper leakage caused by scratching and even die damage of the hardware 71 are prevented, the stability of a product is improved, and the reject ratio of the product is reduced.

The pair of buckling pieces 22 are respectively arranged in the two mounting grooves 211 on the two opposite sides of the line body 21, the buckling pieces 22 can only do axial rotation movement around the pin shaft 23 and can not do movement along the axial direction of the pin shaft 23, the mounting structure stability of the buckling pieces 22 can be improved, and the stability in the processes of die assembly and die release is further ensured.

Referring to fig. 4 and 5, in particular, the locking member 22 includes a locking portion 221 and a force application portion 222 respectively located at two opposite sides of the pin 23, the locking portion 221 is used for being locked with the locking portion 12 of the slide insert group 1; the slide body 21 is provided with an elastic member 24, one end of which abuts against the force application portion 222 to drive the force application portion 222 to rotate around the pin 23, so that the hook portion 221 and the engaging portion 12 are locked. In the mold closing process, the hook parts 221 of the pair of fasteners 22 on the slide seat 2 rotate around the pin shaft 23 and open outwards after contacting the fastening part 12 of the slide insert group 1, and at the moment, the elastic part 24 abutting against the force application part 222 is compressed; when the slide seat 2 moves to the position attached to the slide insert group 1, the latch portion 221 is free from the action of the latch portion 12, the elastic member 24 drives the force application portion 222 to rotate in the opposite direction around the pin 23 to drive the latch portion 221 to buckle the latch portion 12, so that the slide seat 2 and the slide insert group 1 are locked in the demolding direction, and the slide seat 2 can drive the slide insert group 1 to move outward to realize demolding.
