As a kind of preferred version, recess is provided with the concave template, second keeper is placed in recess, and recess In be provided with spring, the spring is butted between the inwall of recess and the second keeper.

Used as a kind of preferred version, the locating part is two for being symmetrical set, and two locating parts are carried out to stripper plate It is spacing.

Used as a kind of preferred version, the elastic component is flat spring, and flat spring is two for being symmetrical set.

Used as a kind of preferred version, extending on the surface of the concave template has multiple guide pillars, the cover plate, clamping plate and de- material Plate is sheathed on multiple guide pillars and up and down along multiple guide pillars.

This utility model has compared with prior art clear advantage and beneficial effect, specifically, by above-mentioned technology Scheme understands：

This utility model includes lower mould and upper mould, lower mould include base plate, concave template, locating part, the first keeper and Second keeper；Mould includes cover plate, clamping plate, stripper plate, punching pin and binder block on this；Stripper plate is pushed, and extrudes binder block Coil, due to being stopped by locating part, stripper plate and binder block are while stress so that the elastic component between stripper plate and clamping plate Deformation, so as to extrude punching pin protrusion work, i.e., flattens to pin, and the pin after stress is pushed because of upper-lower position, only Can from both sides or left and right squeeze, the tension force produced during extruding is run out of by binder block and the second keeper, so as to ensure that foot away from It is stable, improve the stability and qualification rate of product.

More clearly to illustrate architectural feature of the present utility model and effect, come right with specific embodiment below in conjunction with the accompanying drawings This utility model is described in detail.

Specific embodiment

Refer to shown in Fig. 1 to Fig. 4, that show the concrete structure of the preferred embodiment of this utility model, include Lower mould 10 and upper mould 20.

The lower mould 10 includes base plate 11, concave template 12, locating part 13, the first keeper 14 and the second keeper 15；Should Concave template 12 is fixed on the surface of base plate 11, and the locating part 13 is fixed on the surface of concave template 12, in the present embodiment, spacing Part 13 is two for being symmetrical set, and the upper mould 20 of two locating parts 13 pairs carries out spacing；First keeper 14 is fixed on die The surface of plate 12, second keeper 15 is resiliently mounted on the surface of concave template 12, the second keeper 15 and the first keeper 14 Between be formed with cavity 101 for placing coil；Recess 121 is provided with above-mentioned concave template 12, second keeper 15 is put In recess 121, and spring 30 is provided with recess 121, the spring 30 be butted on the inwall of recess 121 and the second keeper 15 it Between.
