Description

Slider one-piece core-pulling structure

technical field

The present invention relates to the field of moulds, in particular to a molding and demoulding structure.

Background technique

In the existing injection mold, the original mold structure is that the slider is inserted into the base, the slider is provided with the shape of a port for forming the product, and the base is used to place the product. After the forming is completed, the slider The block is pushed out, and the product is then processed for demoulding. The disadvantage of this structure is that when the number of products processed at one time increases, the stroke of the slider will be too long, so it is not convenient for simultaneous demolding of multiple products, that is, it cannot be opened too much to make a set of molds The quantity of products directly affects the efficiency of the injection molding machine.

Contents of the invention

The technical problem to be solved by the utility model is to provide a mold structure that is convenient for simultaneous demoulding of multiple products.

The technical scheme that the utility model solves its technical problem adopts is:

Slider one-piece core-pulling structure, including a base and two sliders, the upper surface of the base is provided with a plurality of molding grooves corresponding to the shape of the product, the sliders are located below the molding grooves, each slider Including interconnected inner core-pulling and sliding head, the two inner core-pulling are respectively inserted into the interior of both sides of the base, the upper surface of the inner core-pulling is provided with a demoulding groove, and the distance between adjacent demoulding grooves is the same as that of the adjacent The forming grooves are equally spaced.

As a further description of the one-piece core-pulling structure of the slider above, the number of demoulding grooves is the same as the number of forming grooves.

As a further description of the integrated core-pulling structure of the above slider, two inner core-pulling structures are placed opposite each other.

As a further description of the integrated core-pulling structure of the above slider, the number of demoulding grooves of the two inner core-pullings is the same.

As a further description of the integrated core-pulling structure of the above-mentioned slider, the cross-sectional area of the sliding head is larger than the cross-sectional area of the inner core-pulling, and the side of the sliding head is close to the side edge of the base, and the side of the sliding head is close to the side edge of the base. The side edge contact is a vertical plane, and the inner core is perpendicular to the side edge of the base.

As a further description of the integrated core-pulling structure of the slider above, the arrangement direction of the demoulding grooves is perpendicular to the direction where the forming grooves are located.

The beneficial effects of the utility model are: driven by the oblique guide column of the front mold, the inner core of the slider is provided with a demoulding groove, and the slider is pushed into the base during normal processing. At this time, the demoulding groove is located between the two forming grooves. When the processing is completed, it is only necessary to move the demoulding groove by one station, that is, to move to the same vertical line as the demoulding groove and the forming groove, and then the demoulding can be carried out. It is more convenient to remove the entire slider, and at the same time, the number of simultaneous processing can be increased to improve efficiency.

Detailed ways

As shown in Figures 1 to 4, the integrated core-pulling structure of the slider described in this embodiment includes a base 1 and two sliders 2, and the upper surface of the base is provided with a plurality of molding recesses corresponding to the shape of the product. Groove 11, the slider 2 is located below the molding groove 11, each slider 2 includes an inner core-pulling 21 and a sliding head 22 connected to each other, and the two inner core-pullings are respectively inserted into the interior of both sides of the base, the said The upper surface of the inner core-pulling is provided with demoulding grooves 23 , and the distance between adjacent demoulding grooves 23 is the same as the distance between adjacent forming grooves 11 .

As a further description of the integrated core-pulling structure of the slider above, the number of the demoulding grooves 23 is the same as the number of the molding grooves 11 .

As a further description of the above-mentioned integrated core-pulling structure of the slider, two inner core-pulling elements 21 are placed opposite to each other.

As a further description of the slider integrated core-pulling structure, the number of demoulding grooves 23 of the two inner core-pullings 21 is the same.

As a further description of the integrated core-pulling structure of the above-mentioned slider, referring to FIG. The contact between the side of the head and the side edge of the base is a vertical plane, and the inner core-pulling 21 is perpendicular to the side edge of the base 1 .

As a further description of the integrated core-pulling structure of the above-mentioned slider, the arrangement direction of the demoulding grooves 23 is perpendicular to the direction where the forming grooves 11 are located.

The whole operation process of the new model is that the core-pulling 21 inside the slider has a plurality of demoulding grooves 23. When processing, the slider 2 is attached to the base 1, as shown in Figure 2. At this time, the demoulding grooves of the slider 2 23 is located between the molding grooves 11, so that it can be formed normally; after the two are processed, move the slider 2 so that the demoulding groove 23 of the slider 2 just reaches the product demoulding position, as shown in Figure 3, that is, demoulding The groove 23 and the forming groove 11 are located on the same vertical line, and the demoulding can be carried out at this moment, which is more convenient than the need to remove the whole slide block 2 before, and can increase the quantity of simultaneous processing at the same time.

FIG. 5 is a structural diagram of the combination part of the product 3 and the inner core-pulling 21 .

According to the disclosure and teaching of the above specification, those skilled in the art to which the present utility model belongs can also make appropriate changes and modifications to the above embodiment. Therefore, the utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also be included in the protection scope of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for convenience of description, and do not constitute any limitation to the present invention.
