Description

Technical Field

[0001] The utility model relates to the technical field of stamping processing, in particular to a quick demoulding device for stamping parts. Background Art

[0002] Stamping is a forming method that relies on a press and a die to apply external force to plates, strips, tubes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining a workpiece of the desired shape and size. Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject the sheet material to a deformation force in the die and deform it, thereby obtaining product parts of a certain shape, size and performance. Sheet material, die and equipment are the three elements of stamping. According to the stamping temperature, it is divided into hot stamping and cold stamping. The former is suitable for sheet material processing with high deformation resistance and poor plasticity; the latter is carried out at room temperature and is a commonly used stamping method for thin plates. It is one of the main methods of metal plastic processing and also belongs to material forming engineering technology.

[0003] In the production process of stamping parts, demoulding is an important link. The traditional demoulding method of stamping parts is usually to remove the stamping parts from the mold manually or mechanically. As a result, there are often risks when the stamping parts are taken out. It is easy to cause the stamping machine to press down due to accidental touch, which can easily cause harm to the staff. While the demoulding efficiency is low, the operators need to be in repetitive work for a long time, which poses a safety hazard.

[0004] Therefore, it is necessary to propose a new type of stamping parts rapid demoulding device, which can improve demoulding efficiency, reduce labor intensity, and improve production efficiency and safety. Utility Model Content

[0029] The top of the die 3 is threadedly connected with a plurality of bolts to fully fix the pad 2 and the die 3, and the top of the bolt is flush with the top of the die 3, and will not affect the sliding of the raw materials. With the help of the bolt connection, it is also more convenient for the staff to remove the die 3 for inspection and maintenance.

[0030] See also Figures 1 to 5 In order to eject the formed stamping part from the die 3, a push block 10 is fixedly connected to the top of the push plate 5;

[0031] A push plate 5 is slidably connected between the two pads 2, so that the push block 10 slides up and down with the push plate 5, so that the push block 10 is pushed up and the stamping part is ejected from the die 3. A guide groove 4 is provided on the adjacent side of the two pads 2. The inner wall of the guide groove 4 is slidably connected with a guide block 18. The outer wall of the guide block 18 is fixedly connected to the outer surface of the push plate 5.
