Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. Such as Figure 1-11 As shown, the injection mold of the fixed ring includes a movable mold 1 and a fixed mold 2, the fixed mold 2 includes a first cavity, a runner 4 and a gate 5, and the movable mold 1 includes a second cavity 6, so The second cavity 6 is semicircular, figure 1 , 2 It is just one of the arrangements of the present invention, and for the convenience of observation, figure 1 The movable mold 1 and the fixed mold 2 are removed from the left side of the middle mold, figure 2 The left side of the middle mold removes the movable mold 1 and the fixed mold 2, and the right side of the mold removes the movable mold 1, and figure 2 The fixed ring 3 formed by injection molding in one of the mold cavities is removed on the right side. Such as Figure 5 As shown, the bottom of the inner wall of the second cavity 6 is formed with a...

Abstract

The invention relates to an injection mold for a fixed ring, which includes a movable mold and a fixed mold, the fixed mold includes a first cavity, a runner and a gate, the movable mold includes a second cavity, and the second cavity It is semicircular, the bottom of the inner wall of the second cavity is formed with a first semicircular groove, and the top of the first semicircular groove is formed with a second semicircular groove, and the gap between the first semicircular groove and the second semicircular groove The spaces are separated by semicircular ridges. The structure of the first cavity is the same as that of the second cavity. The movable mold also includes a guide slider, and the guide slider includes a lower transmission block and a The matching block of the upper part is equipped with eight slide blocks. Compared with the prior art, the present invention has the advantages that the fixed ring can be injection-molded at one time, the manufacturing process is simplified, the cost is reduced, the production efficiency is improved, and the stable release of the fixed ring is realized through eight slide blocks.

Description

technical field [0001] The invention relates to an injection mold, in particular to an injection mold for a fixed ring. Background technique [0002] In automobile pipelines, ferrule-type joints are usually used in China to connect through ferrule nuts. In order to prevent the joint from leaking gas, it is necessary to use a wrench to tighten the joint, but in the structure of the car, many places or positions where the joint is installed have a relatively small operating space, and it is quite difficult to use tools such as a wrench. Patent CN201820617440.5 discloses a self-locking fixing device for a push-in joint, which includes a fixing ring 3 that can realize quick installation, such as Figure 11 As shown, the end of the fixed ring 3 is formed with a fixed snap ring 32 , the inner wall of the fixed ring 3 protrudes inward near the middle to form a buckle 33 , and the corresponding outer wall forms a concave groove 31 . However, the structure of the fixed ring 3 is com...
