[0002] Molds are called the mother of industry. The level of mold production and development is one of the important indicators of the level of mechanical manufacturing. With the rapid development of the manufacturing industry, humans have high demands for the quality, weight and appearance of products. There are many ways to mold plastic products. About half of the world's plastic products are molded by injection molds, which can efficiently produce products.

[0003] When there are two-way demoulding undercuts on the product, the traditional design is to design a movable insert in the ordinary slider. After the ordinary slider moves, the product and the movable insert are taken out together, and the movable insert needs to be manually disassembled and assembled. This leads to increased mold manufacturing and product manufacturing costs (mold manufacturing and maintenance costs, injection molding production costs, labor costs), poor product quality and other problems. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that it is difficult to completely demould a product with a simple and low-cost structure when the product has demoulding undercuts in two directions, and proposes a novel inner side core-pulling composite structure of a slider.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A novel slider internal side core-pulling composite structure comprises a slider base fixedly arranged on a rear mold, and also comprises: a slider seat slidably arranged on the slider base, wherein a first insert is fixedly arranged on one end of the slider seat, and a driving part for driving the slider seat to slide is arranged on the slider base; a limit seat, wherein the limit seat is fixedly arranged on the rear mold, wherein a second insert is slidably arranged on the limit seat, and when the slider seat slides, the second insert approaches or moves away from the product.

[0008] In order to improve the sliding effect, further, the vertical grooves are symmetrically provided with two groups, the limit blocks are symmetrically provided with two groups, and the two groups of limit blocks are respectively slidably connected to the corresponding vertical grooves.

[0009] In order to facilitate the first insert to drive the second insert to slide, preferably, a slide groove is opened on the first insert, and a limiting column is fixedly provided on the second insert. The limiting column is slidably set in the slide groove, and the outer wall of the limiting column is against the inner wall of the slide groove.

[0010] Furthermore, an oblique guide groove is formed on the second insert, an oblique guide block is fixedly provided on the first insert, and the oblique guide block is slidably connected in the oblique guide groove.

[0011] Furthermore, the long side of the slide groove and the long side of the inclined guide block are parallel to each other.

[0025] Example:

[0026] Reference Figure 1-Figure 4, a novel slider internal side core-pulling composite structure, comprising a slider base 1 fixedly arranged on a rear mold, and also comprising: a slider seat 2 is slidably arranged on the slider base 1, wherein a groove is opened in the slider base 1, the slider seat 2 is slidably arranged in the groove, and pressure strips 103 are fixedly arranged on the inner wall of the groove, and the top and bottom of the slider seat 2 are respectively against the pressure strip 103 and the bottom of the groove. When in use, by starting with a groove in the slider base 1 and fixing the pressure strip 103 in the groove, the slider seat 2 can be ensured to slide reliably, and the slider seat 2 can be prevented from slipping from the slider base 1 during use, affecting normal use. A first insert 201 is fixedly arranged on one end of the slider seat 2, and a driving part for driving the slider seat 2 to slide is arranged on the slider base 1. When in use, the slider seat 2 is driven to slide back and forth on the slider base 1 by the driving part, and the slider seat 2 can slide with the first insert 201 to achieve mold closing or demolding; a limited position seat 3 is fixedly arranged on the rear mold, wherein the limit seat 3 is provided with a second insert 4 for sliding movement. When the slider seat 2 slides, the second insert 4 approaches or moves away from the product to achieve mold closing or demoulding. When demoulding, the slider seat 2 slides with the first insert 201 to move away from the product to achieve the first demoulding, that is, demoulding in the horizontal direction. At this time, the limiting block 402 on the second insert 4 is in the vertical groove 301 on the limiting seat 3, and the second insert 4 remains in the current state and does not move. The limiting column 401 slides in the slide groove 202. When the first insert 201 continues to move away from the product, After a certain distance, the second insert 4 slides downward along the limit seat 3 to achieve the second demoulding, that is, demoulding in the vertical direction. When the limit block 402 on the second insert 4 slides out of the vertical groove 301, the outer wall of the limit column 401 abuts against the inner wall of one end of the slide groove 202. At this time, the first insert 201 can carry the second insert 4 away from the product in the horizontal direction, and the limit block 402 slides out of the limit seat 3 from the avoidance groove 302, realizing a complete demoulding process. The structure is simple, the manufacturing cost is reduced, and the product quality can be improved.

[0027] When in use, the first mold release is achieved by sliding the first insert 201 away from the product through the slider seat 2. When the first insert 201 continues to move away from the product for a certain distance, the second mold release is achieved by sliding the second insert 4 downward along the limit seat 3. This can solve the problem of complete mold release when the product has mold release undercuts in two directions. It has a simple structure and low cost, and helps to improve product quality. By providing an inclined guide groove 403 on the second insert 4 and fixing an inclined guide block 203 on the first insert 201, it can be ensured that the second insert 4 can slide reliably on the first insert 201 to prevent deflection and affect the processing quality.

[0028] Reference Figure 3A vertical groove 301 is opened on the limit seat 3, and a limiting block 402 is fixedly arranged on the outer wall of the second insert 4, the limiting block 402 is slidably connected with the vertical groove 301, and an avoidance groove 302 connected with the vertical groove 301 is opened on the limit seat 3. When in use, by opening the vertical groove 301 on the limit seat 3 and fixing the limiting block 402 on the second insert 4, it can be ensured that the second insert 4 can slide up and down along the vertical groove 301 reliably to achieve the demoulding effect.

[0029] Reference Figure 3 Here, according to actual usage, we preferably symmetrically open two groups of vertical grooves 301, and also symmetrically set two groups of limit blocks 402, and the two groups of limit blocks 402 are slidably connected to the corresponding vertical grooves 301 respectively. When in use, by opening two groups of vertical grooves 301, it can further ensure that the second insert 4 can slide reliably, so that the force is evenly applied, which helps to improve the use effect.

[0030] Reference Figure 2-Figure 4 A slide groove 202 is provided on the first insert 201, and the slide groove 202 is provided with two to six groups, preferably two groups, and is symmetrically arranged. A limiting column 401 is fixedly arranged on the second insert 4, and the limiting column 401 is provided with two to eight groups, preferably two groups. The two groups of limiting columns 401 are slidably set in the corresponding slide grooves 202 respectively, and the outer wall of the limiting column 401 is abutted against the inner wall of the slide groove 202. When in use, the slide groove 202 is provided on the first insert 201, and the limiting column 401 is fixedly provided on the second insert 4. During demoulding, when the first insert 201 slides a certain distance, the limiting column 401 abuts against the inner wall of one end of the slide groove 202, and the first insert 201 can slide with the second insert 4 to achieve a complete demoulding effect. Conversely, during mold closing, the limiting column 401 can abut against the inner wall of the other end of the slide groove 202 to achieve a mold closing effect.

[0031] Reference Figure 2 and Figure 3 An inclined guide groove 403 is provided on the second insert 4, and an inclined guide block 203 is fixedly provided on the first insert 201. The inclined guide block 203 is slidably connected in the inclined guide groove 403, and the long side of the slide groove 202 is parallel to the long side of the inclined guide block 203. When in use, by providing an inclined guide groove 403 on the second insert 4 and fixing the inclined guide block 203 on the first insert 201, the second insert 4 can be guaranteed to slide reliably and the product quality can be improved.

[0032] Reference Figure 1The driving part can use a cylinder, a hydraulic cylinder, or an electric telescopic cylinder to drive the slider seat 2 to slide to achieve mold closing or demolding. Here, we design the driving part according to actual usage: an oil cylinder 102 is fixedly arranged on the slider base 1, wherein a mounting plate 101 is fixedly arranged on the slider base 1, one end of the oil cylinder 102 is fixedly connected to the mounting plate 101, and a connecting block is slidably arranged in the slider seat 2, and the connecting block is fixedly connected to the output end of the oil cylinder 102. When in use, the slider seat 2 is driven by the oil cylinder 102 to slide along the slider base 1, which is convenient for demolding or mold closing and improves the use effect.
