Description

Technical Field

[0001] This utility model relates to the field of molds, and in particular to a plate hole mold. Background Technology

[0002] Plate hole molds are molds used to punch holes in sheet metal. They are mainly used to punch holes of various shapes and sizes in sheet metal, plastic and other materials. They are widely used in industrial manufacturing, such as automobile manufacturing, electronics manufacturing and aerospace manufacturing, all of which require the use of plate hole molds.

[0003] A plate hole mold is generally divided into three layers. The bottom layer is the base of the plate hole mold, the middle layer is the core part of the entire mold, and the middle layer can be used to determine the shape and size of holes. The top layer is mainly used to seal the top of the middle layer. Through the cooperation of the three layers, holes of various shapes and sizes can be punched on metal and plastic plates.

[0004] After the existing plate punching mold has finished punching the plate, when the upper template is removed, the plate will stick to the inner bottom wall of the upper template, making it difficult to remove the upper template. If it is forcibly removed, it will cause some damage to the template or the plate inside the mold.

[0005] Therefore, it is necessary to provide a new plate hole mold to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a plate hole mold.

[0007] The plate hole mold provided by this utility model includes a base, on which two mold bodies are provided. Two mounting plates are fixedly connected to both sides of the base. The two mounting plates are respectively located on both sides of the mold body on the same side. Corrugated guide holes are opened on the mounting plates. Limiting rods are slidably connected in the guide holes. Mounting rods are fixedly connected between the limiting rods on both sides of the mold body. The mounting rods are located above the mold body on the same side. Several long pressure rods and short pressure rods are respectively provided at the bottom of the mounting rods.

[0008] Preferably, both sides of the base are fixedly connected to rails, and two transmission frames are slidably connected in each rail. Each transmission frame has a sliding groove on the side near the limiting rod on the same side, and the transmission frame is slidably connected to the limiting rod on the same side through the sliding groove.

[0009] Preferably, heat-conducting plates are fixedly connected to the bottom ends of both the long and short pressure rods, and several heat sinks are fixedly connected to the surfaces of both the long and short pressure rods.

[0010] Preferably, one side of the base is rotatably connected with a shaft rod in the track, both ends of the shaft rod are provided with reciprocating lead screws, the reciprocating lead screws are rotatably connected with the transmission frame on the same side, one end of the track is fixedly connected with a motor, and the output end of the motor is fixedly connected with the end of the shaft rod.

[0011] Preferably, the mold body is composed of a bottom die plate, a middle die plate and a top die plate.

[0012] The bottom die plate is fixedly connected to the base, the middle die plate is arranged above the bottom die plate, and the top die plate is arranged above the middle die plate.

[0013] A pouring hole is formed in one side of the top of the top die plate, and protrusions are arranged on both sides of the top of the top die plate.

[0014] Preferably, a plurality of cooling pipes are embedded in the base and fixedly connected, and the cooling pipes are distributed around the mold body.

[0015] Compared with the related art, the plate hole mold has the following beneficial effects:

[0016] The motor drives the reciprocating lead screws to rotate, so that the reciprocating lead screws move back and forth along the track in the movable transmission frame. In this process, the limiting rods are limited and guided through the guide holes, so that the limiting rods and the mounting rods continuously move up and down during the movement. The top of the top die plate is knocked by the long pressing rod and the short pressing rod. The vibration force generated by frequent knocking of multiple points makes the top die plate separate from the plate in the mold body. At the same time, when the top die plate is contacted by the long pressing rod and the short pressing rod, the heat of the top die plate is conducted to the heat dissipation fins through the heat conduction fins, and the multiple heat dissipation fins are used to accelerate the temperature reduction of the inside of the top die plate, thereby effectively improving the auxiliary nature of the device when the top die plate is removed.
