Abstract

The utility model discloses a split type internal inclined pumping mechanism for an injection mold slider, which comprises a slider seat, a slider insert, a slider core, a core fixing column, a limiting screw and a limiting spring; the slider seat is abutted against the slider insert, the slider core is movably sleeved in the core hole of the slider insert, the outer end of the slider core is connected with the core fixing column, the core fixing column is fixed in the slider seat, the limiting screw is sleeved in the stepped hole of the slider insert in a clearance mode and fixedly screwed on the slider seat, and two ends of the limiting spring are respectively abutted against the outer side of the slider insert and the slider seat. Because the utility model discloses during the die sinking, the guide pillar drives take-up housing and slider core to one side and retreats, because the effect of spacing spring, the slider mold insert keeps motionless, retreats a certain distance when the take-up housing, and spacing screw drives the slider mold insert and outwards removes, makes the slider core break away from the product inclined hole along the diagonal direction, has the reliable and stable advantage of action of loosing core.

Description

Split type inside inclined pulling mechanism for sliding block of injection mold

Technical Field

The utility model relates to an injection mold especially relates to a split type inside oblique mechanism of taking out of injection mold slider.

Background

The plastic injection mold is a tool for producing plastic products and has wide application. In the injection molding of plastic products, because some plastic products are provided with inclined holes, bosses and the like, as shown in fig. 1A and fig. 1B, the product 10 is provided with the inclined holes 101, which requires a structure capable of completely extracting the plastic products, but the production of the mold capable of rapidly and conveniently extracting the plastic products has certain difficulty, and the problem to be solved by the technical personnel in the field is always.

Disclosure of Invention

An object of the utility model is to provide a loose core action reliable and stable split type inside oblique mechanism of taking out of injection mold slider.

In order to achieve the above object, the technical solution of the present invention is:

the utility model relates to a split type internal inclined pumping mechanism for a slide block of an injection mold, which comprises a slide block seat, a slide block insert, a slide block core, a core fixing column, a limiting screw and a limiting spring;

the slide block insert is provided with a stepped hole and a core hole, the inner side of the slide block seat is abutted against the outer side of the slide block insert, the slide block core is movably sleeved in the core hole of the slide block insert, the inner end of the slide block core extends into the cavity, the outer end of the slide block core is connected with a core fixing column, and the core fixing column is fixed in the slide block seat; the pan head clearance cover of stop screw is put in the macropore of slider mold insert shoulder hole and stop screw's screw rod passes the aperture of slider mold insert shoulder hole after the fixed spiro union on the slider seat, and limit spring cup joints on stop screw and the both ends of limit spring are leaned on respectively on the outside of slider mold insert and slider seat.

The outer end of the sliding block core is connected with the core fixing column in a groove block matching mode.

The utility model also comprises a shovel machine and an inclined guide post; the shovel machine is propped against the outer side of the sliding block seat, and the inclined guide post is arranged in the guide post hole of the sliding block seat in a penetrating mode.

After the scheme of the above, because the utility model discloses a take-up housing, the slider mold insert, the slider core, the core fixed column, stop screw, spacing spring, during the die joint die sinking, the guide pillar drives the take-up housing to one side and moves back, the slider core also outwards removes, break away from the inclined hole of product, at this moment, because spacing spring's effect, the slider mold insert keeps motionless, back to a certain distance when the take-up housing, stop screw drives the slider mold insert and outwards moves, make the slider core break away from the product along the incline, continue the die sinking, guide pillar drive take-up housing breaks away from the goods completely to one side, the die sinking action is accomplished, ejecting goods, has the reliable and stable advantage of the action of.

The invention will be further described with reference to the accompanying drawings and specific embodiments.

Detailed Description

As shown in fig. 2-7, the utility model relates to a split type inside oblique pump mechanism of injection mold slider, including slider seat 1, slider mold insert 2, slider core 3, core fixed column 4, stop screw 5, spacing spring 6, shovel machine 7 and guide pillar 8 to one side.

The slide block insert 2 is provided with a stepped hole 21 and a core hole 22, and the slide block seat 1 is provided with a guide post hole 11; the upper ends of the shovel machine 7 and the inclined guide post 8 are fixed on the fixed die plate 20, the shovel machine 7 abuts against the outer side of the sliding block seat 1, the inclined guide post 8 penetrates through a guide post hole 11 of the sliding block seat 1 in a clearance mode, the sliding block seat 1 is connected to the movable die plate 30 in a sliding mode, the inner side of the sliding block seat 1 abuts against the outer side of the sliding block insert 2, the sliding block core 3 is movably sleeved in a core hole 22 of the sliding block insert 2, the inner end of the sliding block core 3 extends into a die cavity, the outer end of the sliding block core 3 is connected with a core fixing column 4, and the core fixing column is fixed in the sliding block seat 1; the pan head clearance of stop screw 5 is put in the macropore of slider mold insert 2 shoulder hole 21 and the screw rod of stop screw 5 passes behind the aperture of slider mold insert 2 shoulder hole 22 and fixed spiro union is on slider seat 1, and stop spring 6 cup joints on stop screw 5 and the both ends of stop spring 6 are leaned on respectively on the outside of slider mold insert 2 and slider seat 1.

In this embodiment, the outer end of the slider core 2 is connected to the core fixing post 4 by means of a slot-and-block fit, so that the slider core 2 can slide radially relative to the core fixing post 4.

The utility model discloses a theory of operation:

as shown in fig. 2-4, when the parting surface is opened, the fixed mold plate 20 is separated from the movable mold plate 30 (as shown in fig. 7 and 8), the slide block holder 1 is driven by the inclined guide post 8 to move back, the slide block core 3 also moves outwards to separate from the inclined hole 101 of the product 10, at this time, the slide block insert 2 is kept still under the action of the limit spring 6, when the slide block holder 1 moves back to a certain distance, the limit screw 5 drives the slide block insert 2 to move outwards, so that the slide block core 3 separates from the product 10 in an inclined direction, the mold opening is continued, the inclined guide post 8 drives the slide block holder 1 to completely separate from the product, the mold opening operation is completed, and the product is ejected.

The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited thereby, and all equivalent changes and modifications made within the scope of the claims and the specification should be considered within the scope of the present invention.
