The upper template slides up and down along the guide columns under the action of an external force to approach or move away from the lower template. A backing plate is installed on the bottom surface of the upper template, an upper die fixing plate is installed on the bottom surface of the backing plate, a punch three is installed on the upper die fixing plate, a lower die one is installed on the top surface of the lower template, and the punch three moves up and down under the drive of the upper template and cooperates with the lower die one to complete stamping. The upper die fixing plate is also installed with a punch two. The punch two is inserted into and fixed to the upper die fixing plate from below the upper die fixing plate. The upper die fixing plate is equipped with multiple punch twos of different specifications and one of them is selected for use. The punch two is equipped with a corresponding lower die two, and the lower die two is installed on one side of the lower die. When the punch three and the lower die one perform stamping, the punch two and the lower die two are vertically corresponding and cooperate to perform stamping. The combined mold of the utility model has multiple sets of upper dies and lower dies and is convenient to disassemble.

[0003] During the stamping process of the above combined mold, simple extrusion fixation cannot well achieve the position fixation of the stamped parts. The stamped parts are prone to position deviation due to impact, resulting in stamping misalignment and affecting the qualification rate of the stamped parts. For this reason, the utility model proposes a combined mold to improve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a combined mold to solve the problem that the existing combined mold lacks multi-sided limitation of the stamped parts during the stamping process, resulting in easy position deviation of the stamped parts as mentioned in the above background technique.

A stamping mold is embedded and installed in the middle of the fixed mold. A top mold is arranged above the stamping mold, and a top plate is fixed on the upper side of the top mold. A stamping column is movably arranged in the middle of the top plate, and the stamping column penetrates the top mold and is connected with a stamping head. A forming table is arranged in the middle of the upper side of the bottom plate. Limiting heads are symmetrically arranged on the side surface of the forming table. A connecting rod is fixed to the tail of the limiting head. The connecting rod penetrates the side wall of the bottom mold, and a spring member is sleeved outside the segmented part of the connecting rod located outside the bottom mold.

[0006] Preferably, sleeves are fixed at the corners of the lower side of the top plate, and limiting columns are arranged in cooperation with the sleeves. The limiting columns are fixed to the upper side of the bottom plate.

[0007] Preferably, a limit piece is provided on the lower side edge of the top die, and the limit piece passes through the stamping die, and a stamping piece is provided between the stamping die and the bottom die.

[0008] A positioning rod is symmetrically arranged in the middle of the lower side surface of the top die, and the positioning rod is matched with the positioning hole arranged on the stamping die.

[0009] Preferably, the discharge end of the bottom mold is open, and the forming table is located in the middle of the opening of the bottom mold.

[0010] Preferably, a mounting seat is movably provided at the bottom of the limiting head, the mounting seat is fixed to the upper side of the base plate, and the mounting seat is symmetrically arranged at the edge of the forming table.

[0011] Preferably, a cushion block is provided between the fixed mold and the edge of the bottom mold.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model improves the processing efficiency by setting the punching head to continuously punch and form the punched parts, and the punched workpiece cooperates with the linear movement of the punched parts under the resistance of the limit head to avoid the position deviation of the punched parts during the punching process. The limit head automatically resists the side of the punched workpiece under the joint action of the connecting rod and the spring part.

[0014] Specifically, under the action of external drive, the stamping column drives the stamping head to impact the stamping part arranged between the stamping die and the bottom die. Under the supporting action of the forming table, the stamping part is formed. With the continuous movement of the stamping part, the formed stamping part moves along the forming table, and then enters into the clamping range of the limit head and the forming table. Under the elastic action of the spring part, the connecting rod drives the limit head to contact the formed workpiece. BRIEF DESCRIPTION OF THE DRAWINGS
