Description

Technical Field

[0001] The utility model relates to mold technology, in particular to a slider structure for angle demoulding. Background Art

[0002] A plastic mold is a tool used to produce plastic products. It consists of several groups of parts, each containing multiple molding cavities. Its advantages include high production speed and efficiency, automated operation, a wide variety of designs and shapes, from simple to complex, and sizes from large to small. Furthermore, it produces precise product dimensions, is easily updated, and can produce complex shapes.

[0003] When a product has an inclined part, an oblique pull-out slider is required. The usual solution is to use an oil cylinder or an air cylinder to directly drive the slider to be pulled out, or to add a template to make an oblique shovel mechanism at the bottom of the mold core. However, adding an oil cylinder, an air cylinder or a template will affect the design of the mold, greatly increase the size and weight of the mold, make the mold complex, and make the mold inconvenient to repair and maintain. Utility Model Content

[0004] In order to solve the defects of the above-mentioned prior art, the utility model provides a slider structure for angle demolding, in which a slider seat and an inclined guide column are added to the mold core. The slider can be quickly pulled out obliquely through the movement of the mold itself, without the need to add an oil cylinder, an air cylinder or a template, which greatly reduces the mold volume and the mold weight. The mold structure is compact and simple, and the mold is easy to repair and maintain.

[0005] In order to achieve the above technical objectives, the present invention adopts the following technical solutions: a slider structure for angle demolding, which is arranged on the lower mold, including a mold core, a slider, a slider seat, and a driving unit.

The slide groove is connected to the forming cavity. The slide groove is parallel to the inclined part of the product. The slider moves along the slide groove. Both sides of the bottom end of the slider are provided with protrusions. The slider seat is provided with a guide groove that cooperates with the bottom of the slider. The straight line where the guide groove is located intersects with the straight line where the slide groove is located. Both sides of the guide groove are provided with grooves that cooperate with the protrusions. The slider seat is driven away from or close to the mold core by the driving unit to drive the slider to move along the slide groove.

[0006] Preferably, the driving unit includes an inclined guide column and a shovel block, the top end of the inclined guide column is fixed to the shovel block, the shovel block is assembled on the slider seat, and the bottom end of the inclined guide column is fixed to the lower template.

[0007] Preferably, the guide groove is provided at one end of the slider seat facing the mold core, and a guide post groove is provided on the side of the slider seat away from the mold core, and the oblique guide post passes through the guide post groove.

[0023] Example 1:

[0024] like Figure 1-4 shows a slider 3 structure for angle demoulding, which is arranged on the lower mold, including a mold core 2, a slider 3, a slider seat 4, and a driving unit. The mold core 2 and the slider seat 4 are both arranged on the lower template. A molding cavity 9 and a slide groove 10 are provided on the mold core 2. The molding cavity 9 is used to accommodate the product 1. The slide groove 10 is connected with the molding cavity 9. The slide groove 10 is parallel to the inclined part of the product 1. The slider 3 moves along the slide groove 10. Both sides of the bottom end of the slider 3 are provided with protrusions. The slider seat 4 is provided with a guide groove 41 that cooperates with the bottom of the slider 3. The straight line where the guide groove 41 is located is perpendicular to the straight line where the slide groove 10 is located. Both sides of the guide groove 41 are provided with grooves that cooperate with the protrusions. The slider seat 4 is driven by the driving unit to move away from or close to the mold core 2 to drive the slider 3 to move along the slide groove 10.

[0025] The angle demoulding slider 3 structure of this embodiment is provided with a slider seat 4, an inclined guide column 5 and a shovel block 6 on the lower template. The slider 3 can be quickly and obliquely pulled out through the movement of the mold itself without adding external devices such as oil cylinders, air cylinders or templates, which greatly reduces the mold volume and mold weight. The mold structure is compact and simple, and the mold is easy to repair and maintain.

[0026] The driving unit includes an inclined guide column 5 and a shovel block 6. The top end of the inclined guide column 5 is fixed to the shovel block 6. The shovel block 6 is assembled on the slider seat 4. The bottom end of the inclined guide column 5 is fixed to the lower template.

[0027] The guide groove 41 is provided at one end of the slider seat 4 facing the mold core 2 , and a guide post groove 42 is provided at the side of the slider seat 4 away from the mold core 2 , through which the oblique guide post 5 passes.

[0028] A pressing block 7 is provided on the chute 10 , and the pressing block 7 is used to press the slider 3 into the chute 10 .

[0029] Both sides of the slider seat 4 are provided with a pressure strip 8 and a pressure plate. The pressure plate is fixed on both sides of the slider seat 4. The pressure strip 8 limits the pressure plate to the lower template.

[0030] Working principle: The setting of the protrusion makes the bottom of the slider 3 form a T-shaped structure, and the slide groove 10 and the groove cooperate to form a T-shaped groove that cooperates with the bottom of the slider 3. In actual use, the lower template and the mold core 2 are separated, and the lower template drives the inclined guide column 5 to move downward, and the inclined guide column 5 drives the slider seat 4 to move backward, so that the slider 3 moves horizontally backward and downward, and cooperates with the pressure block 7 and the slide groove 10 to limit the slider 3 to escape from the product 1 along the inclined direction of the inclined part of the product 1, which simplifies the structure and reduces the mold size.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention.
