[0002] There are many kinds of rubber products, but their production processes are basically the same. The production process of products with general solid rubber as raw material mainly includes raw material preparation, plasticizing, mixing, molding, vulcanization, finishing and inspection. When the rubber is extruded, the molding method is generally used to manufacture rubber products with complex shapes such as leather cups and sealing rings. The rubber is placed in the mold with the help of the molded negative and positive molds and heated to form.

[0003] For example, the patent with publication number CN220826223U specifically discloses a rubber molding mechanism, including a feeding device, an extrusion device, a base, a slide slot, a sliding block, a fixed block, a support column and a second fixed plate. Thus, molds of different shapes can be quickly replaced as needed to meet the production needs of different types of rubber products, thereby improving work efficiency and being more practical.

[0004] When the above patent is used, the rubber molding mechanism needs to use the upper and lower molds to press the rubber into the required shape, and the surface of the newly molded rubber is sticky, which makes it difficult to remove the rubber from the mold surface. Pulling the rubber from the outside will cause the rubber to deform, affecting the processing speed of the rubber. At the same time, the rubber is easy to adhere to the inner wall of the rubber molding mechanism when it is removed from the rubber molding mechanism. Therefore, it is necessary to design a rubber pressing molding device to solve the above problems.

[0008] Further, the cleaning unit comprises four groups of fixed blocks mounted on the support plate, the fixed blocks are movably interspersed with multiple groups of limiting rods, the limiting rods are mounted with clamping plates, and the limiting rods are sleeved with second springs;

[0009] A fixing bar is clamped on a side of the clamping plate away from the second spring. The fixing bar has a sliding slot, and the scraper is inserted into the sliding slot.
