Hardware stamping mold, which uses metal plates as the processing object and uses a punch (or hydraulic press) to tear, cut, separate, compress, stretch, and other materials to form products of various shapes that meet people's needs.
Hardware stamping mold composition:
The molds are divided from top to bottom in order: upper mold seat, upper cushion plate, upper clamp plate, stop plate, stripper plate, lower template, lower cushion plate, and lower mold seat. The above is only the most basic, and any template is not generalizable. The mold structure determines the role of the template. According to practical applications, some boards may also be omitted. If no inserts are added to the stripper board, the stop plate can be omitted. If the travel is not enough, it is necessary to add up and down sizing blocks, boards, rods, and up and down pallets. According to different products, the durability of the mold varies, and the regulations of different stamping parts factories may also vary. It is necessary to use it flexibly.
The functions of the components of hardware stamping molds:
1. Upper mold base:
The hanging mold lock punch press is equipped with a guide sleeve and a strong pressure spring, which acts as a shock absorber. During high-speed production, the mold will generate significant vibration, and the mold seat can provide a buffering force. Therefore, the thickness of the mold seat needs to be thicker than other templates, usually around 50. S45 # steel is used, and the material is not heat treated, with a relatively soft hardness, which can protect the punch platform;
2. Upper cushion plate:
Mainly used to pad the punch. The 45 # steel raw material on the upper mold seat is relatively soft, and if the punch directly contacts the mold seat, it is easy to create pits. Therefore, a pad is used instead. Before assembling the mold, the through-hole should be chamfered to remove burrs;
3. Upper clamp plate:
The function of installing auxiliary guide sleeves and fixing punches, also known as punch fixing plates, allows template holes to be chamfered;
4. Stop plate:
The role of locking the guide needle and the stripper plate in the block allows for chamfering between the inner hole and the periphery of the template;
5. Stripping plate:
Its purpose is to place the discharge blade to ensure the accuracy of its position. When the punch is cut, the force provided by the unloading spring separates the punch from the stamping material.
6. Lower template:
The lower template, also known as the blade fixing plate, is used to fix the lower mold blade into the block, bend the mold, float the material block, guide plate, auxiliary guide sleeve, and the template frame edge. Chamfering is not allowed, and the rest can be chamfered;
7. Bottom plate:
The function of the bottom mold parts is to prevent the front side of the blanking hole from being chamfered to prevent excessive chamfering that can easily block the waste and cause material blockage. Other holes can be chamfered, but the back side chamfer of the floating pin hole cannot be too large, as long as the burrs are chamfered;
8. Lower mold base:
The function of the lower mold seat is similar to that of the upper mold seat.
