Abstract

The invention relates to a demoulding device, in particular to a press demoulding device. The invention aims to solve the problem that a greater potential safety hazard exists due to the fact that two push rods need to be supported with hand by people when press demoulding is performed in the prior art. The press demoulding device comprises a pressure head and a working table, wherein the pressure head is located at the upper part of a press; the working table is located at the lower part of the press and used for supporting a workpiece and mould assembly. The press demoulding device also comprises at least two push rods used for demoulding; each push rod is arranged at the upper end of a mould through a magnetic stand arranged at the lower part of the push rod. According to the press demoulding device provided by the invention, the lower end of each push rod is provided with the magnetic stand; the fixation and the disassembly of the push rods can be very easily realized by rotating switches of the magnetic stands; each push rod is fixedly arranged at the upper end of the corresponding mould by adopting a magnetic force, and therefore, the huge potential safety hazard existing when the push rods are manually supported with hand is avoided.

Description

[0001] The patent application of the present invention is a divisional application of the invention patent titled "a press release device", the original application date is December 10, 2013, and the application number is 2013106713455. technical field [0002] The invention relates to a demoulding device, in particular to a demoulding device for a press. Background technique [0003] Currently, two square strips are used as ejector pins to transmit pressure. One end of the ejector pin is placed above the mold, and the press is pressed on the other end of the ejector pin to achieve demoulding. When working, the press must be operated by one person. machine, another person is holding the two ejector pins to demould, there is a great potential safety hazard, and it needs two people to operate, which wastes manpower; in addition, the ejector pins cannot be retracted, so it is necessary to make ejector pins of different heights, resulting in serious resources waste.
