Problems solved by technology

However, the problem with the O-ring double-layer mold structure is that, limited by the multi-layer mold structure, it is difficult to take out the template layer by layer when the mold is opened, which increases the difficulty of blanking, and the blanking time is longer; , Difficulty assembling the formwork, which makes the preparation time for the mold to be put into production longer; these problems lead to a longer cycle of the entire molding process, and steps such as mold opening need to be completed manually, and the labor cost is high, which limits production. further increase in efficiency

Embodiment 1

[0024] The O-ring forming mold includes a fixed template 1 , a movable template 2 , a cavity 3 , a clamping part 21 and a clamping notch 4 .

[0025] Specifically, as figure 1 and 3 As shown, the fixed template 1 is installed on the mounting plate 5 . In this embodiment, the number of movable templates 2 is five, and the movable templates 2 are superimposed on the fixed template 1. The fixed template 1, the movable template 2 adjacent to the fixed template 1, and the upper and lower surfaces of the two adjacent movable templates 2 The mold cavities 3 can be bonded to each other, so that the number of practical mold cavities 3 in one molding process can be greatly increased. In the actual production and manufacturing process, the number of movable templates 2 is at least two.

[0026] Such as figure 1 and figure 2 As shown, each movable template 2 has a strip-shaped clamping portion 21 protruding from the side of the movable template 2 on both sides, the clamping portion ...

Embodiment 2

[0030]The technical solution in this embodiment is basically the same as the technical solution in Embodiment 1. The difference is that in this embodiment, the positioning structure includes a positioning step 1 located on the upper surface of the movable template 2 and a positioning step 1 located on the lower surface of the movable template 2. The gap, the positioning step one is flush with the outer surface of the movable template 2, the positioning gap extends to the side of the movable template 2 and is directly opposite to the positioning step one, and the positioning step one on the movable template 2 can be snapped into the positioning position on the adjacent movable template 2 inside the gap. The positioning structure also includes a positioning step 2 located on the upper surface of the fixed template 1, the positioning step 2 is flush with the outer surface of the fixed template 1, and the positioning step 2 on the fixed template 1 can be snapped into the positionin...

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 ...
