Automobile seat guard plate injection mold

Abstract

The invention provides an automobile seat guard plate injection mold. The automobile seat guard plate injection mold comprises a movable mold, a fixed mold, a fixed mold base plate and a lower mold base, and an inclined core pulling mechanism is connected to the fixed mold base plate; an ejector plate is arranged on the lower mold base, and an inclined ejector is arranged on the ejector plate; multiple locking blocks are arranged on the outer side wall of the movable mold in the circumferential direction, multiple spring bolts and a first elastic piece are arranged on the fixed mold, and multiple unlocking blocks are arranged on the fixed mold base plate; the unlocking blocks are in sliding fit with the spring bolts in the vertical direction, and when the spring bolts and the unlocking blocks slide to a set distance in the vertical direction, the unlocking blocks are used for driving the spring bolts and the locking blocks to be unlocked; and during mold opening, the movable mold moves upwards, the fixed mold moves upwards at the same time, so that the inclined core pulling mechanism is separated from a product, and when the fixed mold moves upwards to a set distance, the spring bolts and the locking blocks are unlocked. According to the automobile seat guard plate injection mold, rapid, effective and stable demolding of an inclined taper hole in the product and an inverted buckle structure in the taper hole can be achieved at the same time.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold for an automobile seat guard plate. Background technique [0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting heated and melted plastic into a mold cavity under high pressure from an injection molding machine, and after cooling and solidifying, a molded product is obtained. [0003] At present, in the design of injection molds, products with multi-button and barb structures are often encountered. The usual method is to force release by using inclined tops or swing rods or using the characteristics of materials combined with the product structure to allow a certain elastic deformation space. mold, but these soluti...

Problems solved by technology

[0003] At present, in the design of injection molds, products with multi-button and barb structures are often encountered. The usual method is to force release by using inclined tops or swing rods or using the characteristics of materials combined with the product structure to allow a certain elastic deformation space. mold, but these solutions are not suitable for some products. For example, there are tapered holes arranged obliquely in the structure of the car seat panel, and there is also an undercut mechanism in the tapered hole. In this case, simply rely on the inclined top The mechanism can only realize the demoulding of the tapered hole, and the undercut mechanism cannot realize synchronous demoulding, that is, the conventional inclined top mechanism can no longer realize the rapid and effective demoulding of the tapered hole and the undercut structure. It is necessary to develop a new convenient two Mold structure with fast and effective demoulding
