Technical Field

The invention relates to the technical field of dies, in particular to a stamping punch forming die.

Background

The die is various dies and tools for obtaining required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production, and is widely used for blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting, and the compression molding or injection molding forming processing of products such as engineering plastics, rubber, ceramics and the like;

the following problems generally occur in the use process of the existing stamping punch forming die:

1. the punch is formed by pouring the melt with higher temperature, and the inside of the punch formed in the mode can have bubbles, so that the quality of the punch is poor, and the service life of the punch is influenced.

2. Because the punch is formed by pouring the melt with higher temperature, the punch can be naturally cooled and formed only by needing longer time, and the production efficiency is lower.

3. Since most of the upper and lower molds are manually separated and the temperature of the outer surface of the mold is high, the operator may be burned.

4. Because the formed punch after die division is still in the die cavity, and the outer surface of the punch is smooth, the operator takes the punch out of the die cavity.

Disclosure of Invention

Technical problem to be solved

Aiming at the defects of the prior art, the invention provides a stamping punch forming die, which solves the problems that the quality of the existing punch is influenced by bubbles mixed in the pouring process, the natural cooling forming efficiency is low, manual die parting can be scalded, and an operator takes out a smooth punch from a die cavity.

(II) technical scheme

In order to achieve the purpose, the invention is realized by the following technical scheme: a stamping punch forming die comprises a workbench, supporting legs, connecting plates and a fixing plate, wherein the supporting legs are distributed at the bottom of the workbench in a rectangular array, the connecting plates are fixed at the top of the workbench, the top end of the connecting plates is fixedly connected with the fixing plate, the top of the workbench is fixedly connected with a driving cylinder, the movable end of the driving cylinder is fixedly connected with a lower die, the bottom of the fixing plate is provided with an opening, the inside of the fixing plate is provided with a cavity communicated with the opening, the inside of the cavity is provided with a movable plate, the bottom of the movable plate is fixedly connected with a fixing block, the bottom end of the fixing block is fixedly connected with an upper die, one side of the connecting plate, which is far away from the lower die, is fixedly connected with a cooling box, the outer surface sleeves of the upper die and the lower die are provided with, one side of the cooling box, which is close to the upper die, is fixedly connected with a water outlet pipe which is fixedly connected with a water return pipe.

Preferably, the outer surface of the lower die is provided with two clamping grooves, the two clamping grooves are embedded in the clamping grooves and connected with clamping blocks, the bottom of each clamping block is fixedly connected with a fixed rod, and the bottom of each fixed rod is fixedly connected with a limiting plate.
