Technical Field

[0001] The utility model belongs to the technical field of rubber moulds, in particular to a material head ejection mechanism for a rubber mould. Background Art

[0002] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force, and can return to its original shape after the external force is removed4. Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is processed from the gum extracted from rubber trees, rubber grass and other plants; synthetic rubber is a polymer made from petroleum and natural gas, with dienes and olefins as monomers.

[0003] Rubber molds are divided into four categories according to the mold structure and product production process: limited molding molds, die-casting molding molds, injection molding molds and extrusion molding molds. Among them, the limited molding mold is also called a compression mold. It puts the semi-finished rubber material directly into the mold, and then sends it to the flat vulcanizer for pressurization and heating. The rubber material is vulcanized under the effect of pressurization and heating.

[0004] After the rubber material is pressurized, heated and vulcanized, a slug will be produced along with the molded product. However, when cleaning the slug, most people manually tear off the slug connected to the product, which increases the labor intensity of the processing workers. Therefore, a rubber mold slug ejection mechanism is proposed to address the above problem. Utility Model Content
