Description

Injection mold for car wash cover

technical field

The utility model belongs to the technical field of machinery and relates to an injection mold, in particular to an injection mold for an automobile cleaning cover plate.

Background technique

Injection mold is tooling equipment used in plastic injection molding process, it is mainly used for molding thermoplastic products. The injection mold consists of two parts, the movable mold and the fixed mold. The movable mold is installed on the movable template of the injection machine, and the fixed mold is installed on the fixed template of the injection machine. Before injection, the movable and fixed molds are closed under the drive of the injection machine to form a mold. Cavity and gating system, the injection machine injects the plasticized plastic melt into the cavity through the gating system, after cooling and solidification, the movable and fixed molds are opened, and the demoulding mechanism pushes out the plastic to complete the injection molding action of a workpiece.

The main molding mechanism of the mold in the prior art is the core and the cavity. According to the different structures of the product and the layout requirements of the pouring system, one mold and multiple cavities can be set. For parts with simple structure and small specifications, one mold can be set to eight The cavity is even a mold of sixteen cavities. However, the setting of this kind of mold is often for one-time molding of the same product, and for automobile molds, due to the symmetry of the automobile structure, if only left-mounted or right-mounted parts of the same structure are formed in one mold, the cost will inevitably increase. Therefore, in the case of one mold with multiple cavities, the method of symmetrically arranging cores and cavities can be used to simultaneously produce a group of parts with symmetrical structures and shapes to save costs.

Contents of the invention

The purpose of this utility model is to solve the above-mentioned problems in the existing technology, and propose a kind of injection mold for automobile cleaning cover, which adopts symmetrically arranged core and cavity, and makes one mold with two cavities, which can make one-time molding and simultaneous production A set of mutually symmetrical products.

The purpose of the utility model can be achieved through the following technical solutions: an injection mold for automobile cleaning cover, including a mold base and a pouring system arranged on the mold base, a guiding mechanism, a demoulding mechanism, and a molding mechanism. It is characterized in that the The molding mechanism described above includes a core and a cavity, and there are two cores and cavities that are arranged symmetrically.

The symmetrical arrangement of the core and the cavity makes the arrangement of the runners of the pouring system simple and facilitates the design and arrangement of the cooling system. At the same time, the structures of the two parts arranged symmetrically are symmetrical to each other, so the injection paths of the runners are the same, and the requirements for the pressure and temperature of the runners are lower, and the injection is easy to achieve balance. The two parts arranged symmetrically make it possible to form a group of mutually symmetrical products with one injection, which reduces the cost of molds, and one set of molds can complete the production of two products.

In the above-mentioned injection mold for car wash cover, the molding mechanism includes a movable template and a fixed template, the above-mentioned two cores are embedded in the movable template, and the above-mentioned two cavities are fixed on the fixed template Inside.

In the above-mentioned injection mold for the car washing cover, the pouring system includes a fixed mold seat plate, a sprue sleeve, and a positioning ring.

In the above injection mold for car wash cover, the demoulding mechanism includes a push rod, a push rod fixing plate, and a push plate, and the push rod passes through the push rod fixing plate and the movable template to abut against the end of the core .

In the above-mentioned injection mold for the car wash cover plate, the guide mechanism includes a guide post arranged on the mold base and passing through the movable die seat plate and the movable template on the mold base, and a guide post arranged on the movable template to communicate with the guide post. matching guide bushing.

Compared with the prior art, the automobile cleaning cover plate injection mold sets a group of symmetrical cores and cavities on the fixed template and the movable template, so that the mold can complete the processing of a group of mutually symmetrical products in one injection molding. , and its cavity structure layout is reasonable, which is convenient for the arrangement of pouring system and cooling system.
