Description

A kind of automobile cover plate injection mold

technical field

The utility model relates to an automobile mold, in particular to an injection mold for an automobile cover plate.

Background technique

In the production of vehicles and automobiles, for example, the covers of some automobile gearboxes, or tailgate covers, airbag covers and other existing technologies are all made by machining, but the efficiency of machining cover parts is low, and it is very difficult Waste of raw materials to a large extent, most of the car cover plates are now made of molds, but the structural design of the car cover plate molds in the prior art is unreasonable, resulting in poor quality of finished products, and some finished products will stick due to the viscosity of injection molding materials In the mold cavity, it is not easy to take out, resulting in relatively low efficiency of injection molding.

Utility model content

The purpose of the utility model is to provide an injection mold for an automobile cover plate with a reasonable structure, which can easily take out the finished product from the mold cavity.

Technical solution: The technical solution adopted by the utility model to solve the problem is: an injection mold for an automobile cover plate, including an upper base and a lower base correspondingly arranged; a connecting rod is installed vertically downward on the lower end surface of the upper base; The lower end of the connecting rod is equipped with a mold body, the middle part of the mold body is provided with a raised mold cavity, the opening direction of the mold cavity is downward, and there are Injection port, the middle of the cavity bottom of the mold cavity is provided with an exhaust port; hydraulic cylinders are installed on both sides of the lower base, and mold covers are installed at the ends of the hydraulic rods of the two hydraulic cylinders. The position of the mold cover Corresponding to the position of the mold body, the mold cavity can be sealed as a whole.

Further, the cross-section of the mold cavity is circular; moreover, a chamfer structure is provided on the mold cavity to make it easier to set the injection molding port.

Further, a sealing groove is provided at the opening end of the mold cavity, and a sealing ring corresponding to the position of the sealing groove is provided on the mold cover plate.

Further, positioning columns are installed at both ends of the mold cover plate, and positioning holes corresponding to the positioning columns are provided on both sides of the mold body, and the positioning columns are installed in the positioning holes.

Beneficial effects: Compared with the traditional technical solutions, the utility model has the following beneficial effects:

(1) The injection mold of the utility model is different from the traditional mold. The mold cavity in the mold body is set with the opening downward, and the mold cover plate corresponding to the mold cavity is correspondingly set at the bottom, and through the hydraulic cylinder The adjustment can be tightly pressed on the mold body to seal the mold cavity, and the injection port and the exhaust port are also set on the mold cavity, and both sides are injected at the same time, and the excess gas is discharged from the exhaust port in the middle, no air bubbles will be generated, and the injection molding After cooling to form the finished cover plate, use the hydraulic cylinder to adjust the mold cover plate downward, and the finished product will fall on the mold cover plate under the action of its own gravity, so it can be easily taken out, even if a certain degree of adhesion is formed in the cavity , it is also easy to take out by external force and its own gravity, so it is very convenient to use;

(2) In the utility model, a sealing groove and a sealing ring are respectively arranged on the opening end of the mold cavity and the mold cover plate, which increases the sealing effect and effectively prevents the injection material from being released from the gap between the mold body and the mold cover plate. If there is any exposed problem, it will increase the sealing effect.

detailed description

Below in conjunction with accompanying drawing and specific embodiment, further clarifies the utility model, and this embodiment implements under the premise of the technical solution of the utility model, and it should be understood that these examples are only used to illustrate the utility model and are not intended to limit the utility model range.

As shown in Figure 1, a kind of automobile cover plate injection mold, comprises the upper base 1 and the lower base 2 that are arranged correspondingly; The lower end of the mold body 4 is installed with a mold body 4, and the middle part of the mold body 4 is provided with a raised mold cavity 5. There is an injection port 6, and an exhaust port 7 is arranged in the middle of the cavity bottom of the mold cavity 5; hydraulic cylinders 8 are installed on both sides of the lower base 2, and mold cover plates 9 are installed at the ends of the hydraulic rods of the two hydraulic cylinders 8, The position of the mold cover plate 9 corresponds to the position of the mold body 4 and can cover the mold cavity 5 as a whole.

The cross-section of the mold cavity 5 is circular; and a chamfer structure is also provided on the mold cavity 5 to make it easier to set the injection port 6; the opening end of the mold cavity 5 is also provided with a ring of sealing grooves 10, and the mold The cover plate 9 is provided with a sealing ring 11 corresponding to the position of the sealing groove 10; positioning columns 12 are also installed at both ends of the mold cover plate 9, and positioning holes 13 corresponding to the positioning columns 12 are provided on both sides of the mold body 4 , the positioning column 12 is installed in the positioning hole 13 .

The injection mold of the utility model is different from the traditional mold. The mold cavity in the mold body is set with the opening downward, and the mold cover plate corresponding to the mold cavity is set at the bottom accordingly, and can be tightly adjusted by the hydraulic cylinder. Press on the mold body to seal the mold cavity, and the injection port and the exhaust port are also set on the mold cavity, both sides are injected at the same time, and the excess gas is discharged from the exhaust port in the middle, no air bubbles will be generated, and the injection molding is completed to be cooled After forming the finished cover plate, use the hydraulic cylinder to adjust the mold cover plate downward, and the finished product will fall on the mold cover plate under the action of its own gravity, so it can be easily taken out, even if a certain degree of adhesion is formed in the mold cavity, through external force And its own gravity is also easy to take out, so it is very convenient to use.

In the utility model, a sealing groove and a sealing ring are respectively arranged on the opening end of the mold cavity and the mold cover plate, which increases the sealing effect and effectively prevents that the injection molding material may be exposed from the gap between the mold body and the mold cover plate. problem, increasing the sealing effect.

The above-mentioned specific implementation is only a preferred embodiment of the utility model, and is not used to limit the implementation of the utility model and the scope of claims. All equivalent changes and Modifications should be included in the scope of the utility model patent application.
