[0002] With the rapid development of intelligent vehicles, the design and manufacture of ICV (Intelligent Connected Vehicle) products require higher and higher safety and reliability for vehicles. As a key connecting structure, the lock catch part in the ICV product directly affects the quality and production efficiency of the product in terms of forming precision and demolding efficiency. In the traditional injection mould design, the forming of the lock catch part usually faces problems such as complex mould structure, low forming precision, and difficult demolding.

[0003] In the traditional mould design, the accurate forming of the lock catch part often requires a relatively complex mould structure, such as using multiple inclined surfaces, protrusions, and other structures to achieve the forming, but these designs usually lead to complex mould structure, tedious production and adjustment process, and are prone to inconsistent forming of the lock catch part. In addition, due to the special shape of the lock catch part, the traditional mould often has problems such as product jamming, sticking, or forming defects during ejection, resulting in low production efficiency, increasing the risk of manual handling, and possibly reducing the service life of the mould.

[0004] In order to improve the forming precision of the lock catch part of the ICV product, reduce the complexity of the mould, and solve the problem of difficult demolding, a new injection mould design scheme is needed, which can simplify the mould structure while ensuring the forming precision, and improve the smoothness of demolding and production efficiency.

[0010] In one embodiment, the first forming part has four guide parts arranged uniformly along the circumference of the inner circle of the product; after the mold is closed, the guide parts are inserted into the upper die core.

[0011] In one embodiment, the guide part is arc-shaped on the outside, and the outside is attached to the inside of the product.

[0012] In one embodiment, the inclined sliding groove is inclined in the direction of the lifting of the push rod, away from the product.

[0013] Compared with the prior art, the utility model has the beneficial effects that:

[0014] (1) The ICV lock injection mold of the utility model adopts the design of inclined sliding blocks cooperating with inclined sliding grooves, realizes the accurate molding of the lock part of the ICV product by setting the inclined sliding blocks and their protrusions and pushing the inclined sliding blocks to slide along the inclined sliding grooves.
