Abstract

The utility model discloses a stamping die of precision, including the mounting bracket, the surface of mounting bracket has the lower mould through the bolt fastening, and the surface symmetry of lower mould is provided with spacing post, and the cylinder is installed to the upper end of mounting bracket, and the god of cylinder end fixed mounting has the mould. The cylinder drives the upper die to move up and down along the limiting post on the surface of the lower die through the limiting hole so as to limit the upper die, so that the displacement caused in the stamping process of the upper die and the lower die can be effectively avoided; when the stamping part takes off the material, thereby go up mould rebound butt and support the piece and drive the pull rod upwards and thus mention the kicking block from the recess with this to taking off the material.

Description

Stamping die of precision part

Technical Field

The utility model relates to a stamping die technical field specifically is a stamping die of precision.

Background

The present invention relates to a mould, various moulds and tools for obtaining required products by using injection moulding, blow moulding, extrusion, die-casting or forging forming, smelting and stamping methods in industrial production.

The upper die of the existing stamping die is generally directly connected with the cylinder and lacks a corresponding limiting structure, when the upper die extrudes with the lower die, the upper die easily generates deviation in the moment of deformation of a stamping part, so that the cylinder cannot be accurately positioned and extruded and is easily damaged, and the stripping device arranged on the surface of the existing lower die adopts a spring ejector pin type structure to strip materials, so that the springs cannot strip the materials due to possible creep deformation and insufficient elasticity caused by long-time use.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a stamping die of precision to solve the stamping die punching press and take place the problem of position.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a stamping die of precision, includes the mounting bracket, the surface of mounting bracket has the lower mould through the bolt fastening, the surface symmetry of lower mould is provided with spacing post, the cylinder is installed to the upper end of mounting bracket, the god end fixed mounting of cylinder has last mould.

Preferably, the surface of the upper die is correspondingly provided with a limiting hole, and the inner side of the limiting hole is connected with a limiting column in a sliding manner.

Preferably, the surface of the upper die is symmetrically provided with guide openings, the inner sides of the guide openings are connected with pull rods in a sliding mode, the upper ends of the pull rods are provided with abutting blocks, and the lower ends of the pull rods are provided with ejector blocks.

Preferably, the surface of the lower die is symmetrically provided with grooves, and the inner sides of the grooves are connected with ejector blocks in a sliding manner.

Compared with the prior art, the beneficial effects of the utility model are that: the cylinder drives the upper die to move up and down along the limiting post on the surface of the lower die through the limiting hole so as to limit the upper die, so that the displacement caused in the stamping process of the upper die and the lower die can be effectively avoided; when the stamping part takes off the material, thereby go up mould rebound butt and support the piece and drive the pull rod upwards and thus mention the kicking block from the recess with this to taking off the material.

Drawings

Fig. 1 is a schematic view of the overall structure of the present invention;

FIG. 2 is a sectional view of the overall structure of the present invention;

fig. 3 is a plan view of the lower mold of the present invention.

In the figure: the device comprises a mounting frame 1, a cylinder 2, an upper die 3, a limiting hole 31, a guide opening 32, a lower die 4, a limiting column 41, a groove 42, a pull rod 6, a top block 61 and a butting block 62.

Detailed Description

Referring to fig. 1 and fig. 3, the present invention provides a technical solution: the utility model provides a stamping die of precision piece, includes mounting bracket 1, and there is lower mould 4 on mounting bracket 1's surface through the bolt fastening, and the surface symmetry of lower mould 4 is provided with spacing post 41, and cylinder 2, the 2 models of cylinder are installed to mounting bracket 1's upper end: JRBL-5B, the upper die 3 is fixedly arranged at the telescopic end of the cylinder 2.

Referring to fig. 2, a limiting hole 31 is correspondingly formed in the surface of the upper mold 3, a limiting post 41 is slidably connected to the inner side of the limiting hole 31, and the limiting hole 31 moves along the limiting post 41 to limit the upper mold 3 to move up and down.

Referring to fig. 2, the surface of the upper die 3 is symmetrically provided with guide openings 32, the inner sides of the guide openings 32 are slidably connected with the pull rod 6, the upper die 3 moves along the pull rod 6 when moving upward, the upper end of the pull rod 6 is provided with a supporting block 62, when the upper die 3 abuts against the supporting block 62, the pull rod 6 is driven to move upward, so as to drive the pushing block 61 to move upward, and the lower end of the pull rod 6 is provided with the pushing block 61.

Referring to fig. 2 and 3, the surface of the lower mold 4 is symmetrically provided with grooves 42, the inner sides of the grooves 42 are slidably connected with a top block 61, when the upper mold 3 is lifted to a top end, the top block 62 is abutted to drive the pull rod 6 to lift the top block 61 upwards along the grooves 42, so as to lift the stamping part on the surface of the lower mold 4.

The utility model discloses when concrete implementation: when the stamping die works, the upper die 3 is connected to the surface of the limiting column 41 of the lower die 4 in a sliding manner through the limiting hole 31, so that the upper die 3 is limited by the movement of the limiting column 41 along the limiting hole 31 in the process that the upper die 3 is driven by the air cylinder 2 to move up and down, and the displacement caused in the stamping process of the upper die 3 and the lower die 4 can be effectively avoided; when the stamping workpiece takes off the material, because pull rod 6 sliding connection is in the inboard of direction mouth 32, consequently go up the in-process pull rod 6 that mould 3 moved up position and can remain unchanged, when last mould 3 butt to support piece 62, will drive pull rod 6 rebound, thereby make kicking block 61 along recess 42 rebound, thereby mention the stamping workpiece on lower mould 4 surface through kicking block 61 and take off the material with this, the spring that can avoid using causes is not enough and creep and the problem that can't take off the material that causes.
