Description

Technical Field

[0001] This utility model relates to the field of product injection molding technology, specifically a slider structure that combines the combined action of arc-shaped core pulling and straight-line core pulling. Background Technology

[0002] During product injection molding, due to a narrow and deep rounded undercut at one corner of the product, such as... Figure 6 As shown, vertical demolding is not possible, and the side appearance is difficult to demold due to the shape. Therefore, a slider structure that combines the actions of arc-shaped core pulling and straight core pulling is needed. Utility Model Content

[0003] The purpose of this invention is to provide a slider structure that combines the combined action of arc-shaped core pulling and straight-line core pulling, in order to solve the problem mentioned in the background art that the prior art cannot eject the mold vertically.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a slider structure combining arc-shaped core pulling and linear core pulling structures, comprising a rear mold assembly and a front mold assembly, which are used together to injection mold a product. The rear mold assembly includes a base plate, a B plate, and a rear mold core. The B plate is mounted on the top of the base plate via a square iron. The rear mold core is disposed on the surface of the B plate. A composite component is mounted on the surface of the B plate. This composite component is used for core pulling of the product.

[0005] Preferably, the front mold assembly includes an A plate and a panel, the top of the A plate is fixed to the panel by bolts, the surface of the A plate is fitted with a front mold core, and the front mold core and the rear mold core cooperate for the injection molding of the product.

[0006] Preferably, the composite component includes a slider, an elongated pressure strip, an arc-shaped pressure strip, and an inner sliding slider, wherein the slider is disposed on the surface of plate B.

[0007] Preferably, elongated pressure strips are provided on both the left and right sides of the slider, and the elongated pressure strips are used to press the slider onto the surface of plate B using bolts.

[0008] Preferably, the two ends of the rear mold core surface are provided with inner sliding blocks, and the inner sliding blocks are fixed to the surface of the rear mold core by arc pressure strips.

[0009] Preferably, the bottom of the elongated pressure strip is provided with grooves on both sides, which are used to fasten and press the inner sliding block.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The slider structure, which combines the arc-shaped core-pulling and straight-line core-pulling structures, utilizes a composite component. During implementation, the inner slider is fixed to the rear mold core by an arc-shaped pressure strip, and the slider is fixed to the B-plate by the pressure strip. A groove on the slider engages and presses against the inner slider. When the slider moves vertically, it drives the inner slider to move, which then performs an arc-shaped motion under the action of the arc-shaped pressure strip. This utility model cleverly and simply combines the mold release direction of the slider with a straight slider-driven arc-shaped slider structure, achieving a composite action function of the arc-shaped core-pulling and straight-line core-pulling structures.

At the same time, in the description of the present utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0019] The present invention provides a slider structure that combines the combined action of arc-shaped and linear core-pulling mechanisms, as shown in the following figure. Figure 1 as well as Figure 2 As shown, the assembly includes a rear mold assembly 1 and a front mold assembly 2, which are used together to injection mold product 10. The rear mold assembly 1 includes a base plate 11, a B plate 12, and a rear mold core 13. The B plate 12 is mounted on the top of the base plate 11 by a square iron, and the rear mold core 13 is provided on the surface of the B plate 12. The front mold assembly 2 includes an A plate 21 and a panel 22. The top of the A plate 21 is fixed to the panel 22 by bolts, and the front mold core is mounted on the surface of the A plate 21. The front mold core and the rear mold core 13 are used for the injection molding of product 10. A composite component 3 is mounted on the surface of the B plate 12. The composite component 3 is used for the core pulling of product 10.

[0020] During implementation, the front mold core and the rear mold core 13 work together for the injection molding of product 10.

[0021] Furthermore, such as Figures 3 to 5 As shown, the composite component 3 includes a slider 4, an elongated pressure strip 5, an arc-shaped pressure strip 6, and an inner sliding block 7. The slider 4 is disposed on the surface of the B plate 12. Elongated pressure strips 5 are provided on both the left and right sides of the slider 4. The elongated pressure strips 5 are used to press the slider 4 onto the surface of the B plate 12 using bolts. Inner sliding blocks 7 are provided at both ends of the surface of the rear mold core 13, and the inner sliding blocks 7 are fixed to the surface of the rear mold core 13 by the arc-shaped pressure strips 6. Grooves 41 are provided on both sides of the bottom of the elongated pressure strips 5. The grooves 41 are used to fasten and press the inner sliding blocks 7.

[0022] During implementation, when slider 4 moves vertically, it drives the inner slider 7 to move. Under the action of the arc pressure strip 6, the inner slider 7 makes arc motion.

[0023] Working principle: During use, the inner core puller 7 is fixed to the rear mold core 13 by the arc-shaped pressure strip 6, and the slide block 4 is fixed to the B plate 12 by the elongated pressure strip 5. The slide block 4 has a groove 41 that catches and presses against the inner core puller 7. When the slide block 4 moves vertically, it drives the inner core puller 7 to move. Under the action of the arc-shaped pressure strip 6, the inner core puller 7 performs an arc-shaped motion, ultimately completing the combined motion of the arc-shaped core pulling and the linear core pulling structure.
