[0002] Stamping rubber molds are widely used in the automotive, electronics, home appliance, and communications industries, and are often used to produce a variety of rubber products. The working principle of a stamping rubber mold is to use the mold on a press to apply pressure to the rubber material, causing it to plastically deform, thereby producing the desired rubber product. During this process, the shape of the mold cavity determines the final shape and size of the rubber product. However, existing stamping rubber molds are cumbersome to debug before operation, the stamping process is complex, and the blanking process is inefficient. Utility Model Content

[0004] The utility model provides the following technical solutions:

[0005] It includes a lower die base, which is inserted into a support rod sleeve and slidably connected to an upper die base through a support rod. A stamping mechanism is provided on the upper die base, and is characterized in that: the stamping mechanism includes a push rod fixing plate, a punch fixing plate, a stripping plate, a punch and a push rod, and a pair of adjusting pads are installed in parallel on the end surface of the push rod fixing plate. In the vertical direction, the stripping plate, the punch fixing plate and the push rod fixing plate are stacked in sequence, and the punch holes of the push rod fixing plate, the punch fixing plate and the stripping plate correspond to each other. The push rod is installed on the push rod fixing plate, and the punch is sleeved on the push rod and passes through the punch fixing plate and the stripping plate in sequence.

[0006] It is further characterized by:

[0007] The punching mechanism includes a push rod fixing plate, which is mounted on the upper die seat through a push seat cylinder, the punch fixing plate is connected to the upper die seat through a side connecting plate, a sliding column is provided between the punch fixing plate and the push rod fixing plate, the stripper plate is connected to the punch fixing plate through a guide column, a center plate is installed in the middle of the push rod fixing plate, and assembly pins are installed in parallel on the center plate, and the assembly pins pass through the push rod fixing plate and are inserted into the punch fixing plate;

[0008] The convex parts on both sides of the ejector fixing plate are clamped with limit blocks, and the limit blocks are installed on the upper die seat.

[0009] The upper die base and the lower die base are respectively provided with a limit column and a limit column plate, and the positions of the limit column and the limit column plate correspond to each other;

[0010] A concave die seat is installed in the middle of the lower die seat, and a concave die plate is installed on the end surface of the concave die seat.

[0011] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0012] The ejector fixing plate in the stamping mechanism is equipped with an adjustment pad, which is used to adjust the relative position of the punch and the ejector, and can change the slope of the trapezoidal shape punched out by the ejector. The debugging is simple, and the ejector can eject the product into the trapezoidal shape first with the punch. The tensile property of the rubber product is utilized to optimize the blanking. The punch enters the concave plate and punches out the product, which improves the blanking processing efficiency and simplifies the stamping process.

[0013] The ejector fixing plate is installed on the upper die base through the ejector cylinder. The ejector cylinder drives the ejector fixing plate to move downward. The ejector on the ejector fixing plate will completely eject the product. The operation is simple and convenient, which further increases the efficiency of the blanking process.

[0014] The main function of the unloading plate is to remove the strip material or waste material on the punch after punching, which facilitates the punching action and indirectly improves the punching efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
