Description

Technical Field

[0001] The utility model relates to the technical field of molds, and more particularly to a progressive mold which is convenient for replacing punches. Background Art

[0002] The progressive die is composed of multiple stations, each of which completes different processing in sequence. A series of different stamping processes are completed in one stroke of the punch press. After one stroke is completed, the punch press feeder moves the material forward according to a fixed step distance. In this way, multiple processes can be completed on a die.

[0003] The existing progressive die requires disassembly of many accessories when replacing the punch, and the die frame must be disassembled to replace the punch. If the punch wears quickly, the die frame needs to be frequently disassembled and assembled, which directly leads to reduced mold accuracy and low disassembly and assembly efficiency. It takes a lot of time and the convenience of punch replacement cannot meet the needs. Therefore, in response to this problem, how to design a progressive die that is easy to replace the punch has become a problem that we currently need to solve. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a progressive die that is convenient for replacing punches. Through the fixing plate and the punch pressure plate, when the punch needs to be replaced, the punch pressure plate fixing screws on both sides can be unscrewed, and the fixing plate and the punch pressure plate can be pulled out from the inside of the upper die frame plate, so that the punch can be disassembled and replaced to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a progressive die for easy replacement of punches, comprising an upper die frame plate and a lower die frame plate, a fixed plate being plugged into the top of the upper die frame plate, a punch pressure plate being fixedly installed on the bottom of the fixed plate, the punch pressure plate being slidably connected to the inside of the upper die frame plate, an upper pad being provided at the bottom of the upper die frame plate, the punch pressure plate being plugged into the inside of the upper pad, a punch fixing plate being provided at the bottom of the upper pad, a punch being plugged into the inside of the punch fixing plate, guide sleeves being fixedly installed at the four corners of the bottom of the upper die frame plate, a guide column being slidably connected to the inner side of the guide sleeve, and the bottom of the guide column being fixedly installed on the lower die frame plate.

[0006] In a preferred embodiment, a lower pad is provided on the top of the lower mold frame plate, and a concave mold plate is provided on the top of the lower pad.

[0007] In a preferred embodiment, a stripper plate is provided on the top of the concave plate, and a spring is provided on the top of the stripper plate.

[0008] In a preferred embodiment, the top end of the spring is fixedly mounted on the bottom of the punch fixing plate.

[0010] Technical effects and advantages of this utility model:

[0011] 1. The utility model provides a fixing plate and a punch pressing plate. When the punch needs to be replaced, the punch pressing plate fixing screws on both sides can be unscrewed, and the fixing plate and the punch pressing plate can be pulled out from the inside of the upper die plate to expose the punch, so that the punch can be disassembled and replaced. After the replacement is completed, the punch pressing plate is reset and the fixing plate is fixed by the punch pressing plate fixing screws, so that the installation is completed by limiting the punch by the punch pressing plate, thereby improving the convenience of replacing the punch.
