Forming die prepared through natural rubber block

Abstract

The invention relates to a forming die prepared through a natural rubber block. The forming die prepared through the natural rubber block comprises an upper die and a lower die, wherein the lower dieis installed at the lower end of the upper die, the upper die comprises an upper die plate, a guide frame, a fixing frame, a die core and a trimming frame, and the trimming frame comprises a sliding block, an annular tool rest, a rotating rod, a C-shaped plate, a control rod, a cross-shaped block, an annular thin plate and a hollow ring. According to the forming die prepared through the natural rubber block, through cooperation of the upper die and the lower die, the upper die plate and the lower die plate are aligned, so that the situation that the quality of a rubber block finished product does not meet the standard is prevented, meanwhile, the product size is limited, the die core is fixed through the fixing frame, meanwhile, the die core can be replaced, and thus rubber blocks with different inner diameter sizes and shapes are prepared and formed, and burrs on the outer side of the parting surface of the rubber block finished product are cleared through the trimming frame, so thatthe quality of the rubber block finished product is improved.

Description

technical field [0001] The invention relates to the field of rubber manufacturing, in particular to a molding die for preparing natural rubber blocks. Background technique [0002] As the use of rubber products becomes more and more widespread, the demand for rubber products is also increasing. Therefore, the use of rubber molds, which can quickly shape and process rubber, is becoming more and more common. Rubber molds are mainly used for In the process environment of strengthening molding pressure or transferring molding pressure, the application of rubber molds has two basic forms, namely fixed volume and variable volume. [0003] In the process of molding the rubber block, due to the physical properties of the rubber and the structural limitations of the mold, the following problems exist in the actual operation process: [0004] (1) The traditional rubber block forming mold and the burrs on the parting surface of the finished rubber block need to be cleaned up later, wh...

Problems solved by technology

[0004] (1) The traditional rubber block forming mold and the burrs on the parting surface of the finished rubber block need to be cleaned up later, which increases the processing cost

[0005] (2) Traditional rubber molds generally use the distance between the upper and lower templates to cut the raw material, and the sheared parts will be staggered and sheared each time the rubber block is formed, resulting in a large amount of wear of the sheared parts, thus Affects subsequent burr removal
