Abstract

The invention provides an O-shaped ring forming mold, belongs to the technical field of molds, and solves the problems of inconvenience for mold opening and high labor cost in a traditional O-shaped ring forming mold. The O-shaped ring forming mold comprises a fixed template, and at least two movable templates stacked on the fixed template up and down; the fixed template, the movable template near the fixed template and the upper and lower surfaces of two adjacent movable templates are mutually bonded to form a molding cavity; strip-shaped clamping parts projected on the side surfaces of the movable templates are respectively arranged on two sides of each movable template; and the clamping parts are thinner than the movable templates, and are near the upper surfaces of the corresponding movable templates to form clamping gaps between the fixed template and the adjacent movable template and between two adjacent movable templates. The O-shaped ring forming mold can be suitable for automatic mechanical mold opening through arranging the clamping parts and the clamping gaps without needing manual mold opening, reduces the labor intensity of workers, and reduces the labor cost.

Description

technical field

[0001] The invention belongs to the technical field of moulds, and relates to an O-ring forming mould. Background technique

[0002] The O-ring is a rubber sealing ring with a circular cross-section, which is widely used in various mechanical equipment for the sealing of liquids and gases. O-rings can play a sealing role in the specified temperature, pressure, and different liquid and gas media, under static or moving conditions.

[0003] O-rings are usually processed by O-ring molding dies. Existing O-ring molding dies, for example, a double-layer mold structure for O-rings disclosed in Chinese Patent [Application No. 200820038631.2; Authorized Notice No. CN201366771Y] includes There are a plurality of O-ring mold cavities formed between the upper mold and the lower mold. There are two upper molds and two lower molds respectively, which constitute the first and second sets of molds respectively. The lower mold of the first set of molds The mold is fixedly ...
