Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a pull-out mold that is easy to demold. Background Technology

[0002] Traditional molds consist of a robust cavity made up of upper and lower molds. The core principle is to inject or press molten material into the cavity under high pressure. After cooling and solidification, the product is separated from the mold by an ejection mechanism, thereby mass-producing products of a specific shape.

[0003] However, traditional molds still have the following drawbacks: According to the design structure of traditional molds, the two slides are driven by the shovel base to move towards the shovel base, which facilitates disengagement. However, in this structure, there are only two slides and the displacement direction is unidirectional, which will cause the product to wrap around the slides, thereby increasing the mold thickness, the number of mold parts, and the manufacturing cost. Utility Model Content

[0004] The purpose of this utility model is to provide a pull-out mold that is easy to demold, in order to solve the problem mentioned in the background art that the number of inner slides is only two and the displacement direction is unidirectional, which leads to the product wrapping the slides, the increase in mold thickness, the number of parts, and thus the increase in cost.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pull-out mold for easy demolding, comprising: The main body includes a mold body, a box is fixedly connected to the surface of the mold body, an oil cylinder is fixedly connected to the bottom side of the mold body, and a support is fixedly connected inside the mold body. The ejection mechanism includes a base plate movably connected to the bottom of the mold body. A shovel base is fixedly connected to the upper surface of the base plate. A straight surface is opened at the bottom side of the shovel base. A first main slide is movably connected to the side of the first main slide. A first auxiliary slide is movably connected to the side of the first main slide. A second auxiliary slide is movably connected to the other side of the first main slide. A second main slide is movably connected to the other side of the shovel base opposite to the position of the first main slide. A third auxiliary slide is movably connected to the side of the second main slide. A fourth auxiliary slide is movably connected to the other side of the second main slide.

[0006] Preferably, a template is fixedly connected inside the mold body, and a through hole is provided in the center of the template.

[0007] Preferably, the bracket is fixedly connected to the edge of the through hole in the mold body.

[0008] Preferably, the cylinder has a guide post that is slidably connected inside, and the other end of the guide post is fixedly connected to the base plate.

[0009] Preferably, the two sides of the shovel base are inclined, and the straight side is located at the bottom of the inclined surface.

[0010] Preferably, the bottom of the first auxiliary position, the second auxiliary position, the third auxiliary position, and the fourth auxiliary position has a plane corresponding to the straight surface.

[0011] Preferably, the surfaces of the first auxiliary slide, the second auxiliary slide, the third auxiliary slide, and the fourth auxiliary slide are fixedly connected with two sets of T-shaped sliders, and the surfaces of the first main slide and the second main slide are provided with two sets of sliding grooves, and the shape of the sliding grooves corresponds to the shape of the T-shaped sliders.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This easy-to-demold pull-out mold, by setting a straight surface, allows the first, second, third, and fourth auxiliary slides to move towards the first and second main slides during displacement. When the base moves down a certain distance and leaves the lowest surface of the auxiliary slide, the auxiliary slide will then move towards the base along with the first and second main slides. This increases the number of slides and the number of movement directions, achieving one-time demolding and avoiding product wrapping around the slides.

[0013] 2. This easy-to-demold pull-out mold, by setting up a box, support and shovel base and other mechanisms, reduces the mold thickness space, optimizes the mold structure, and allows the injection molding machine to select smaller specifications, saving costs. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-6 One embodiment provided by this utility model: A pull-out mold for easy demolding, comprising: The main body includes a mold body 1, a box 11 is fixedly connected to the surface of the mold body 1, an oil cylinder 12 is fixedly connected to the bottom side of the mold body 1, and a bracket 13 is fixedly connected inside the mold body 1. The above structures together realize the injection molding process of the device. The ejection mechanism includes a base plate 2, which is movably connected to the bottom of the mold body 1. A shovel base 21 is fixedly connected to the upper surface of the base plate 2. A straight surface 22 is opened at the bottom side of the shovel base 21. A first main slide 23 is movably connected to the side of the first main slide 23. A first auxiliary slide 24 is movably connected to the side of the first main slide 23. A second auxiliary slide 25 is movably connected to the other side of the first main slide 23. A second main slide 26 is movably connected to the other side of the shovel base 21 opposite to the position of the first main slide 23. A third auxiliary slide 27 is movably connected to the side of the second main slide 26. A fourth auxiliary slide 28 is movably connected to the other side of the second main slide 26. The above structure causes the slides to move during the downward displacement of the shovel base 21, thereby demolding the product.

[0018] Furthermore, a template is fixedly connected inside the mold body 1, and a through hole is provided in the center of the template. The above structure allows the shovel base 21 to move vertically inside the mold body 1.

[0019] Furthermore, the bracket 13 is fixedly connected to the edge of the through hole of the mold body 1. The bracket 13 also has a through hole in the center, and the position and size of the through hole are basically corresponding to the position and size of the mold body 1, so that the shovel base 21 can move vertically in the through holes of the mold body 1 and the bracket 13 at the same time.

[0020] Furthermore, the cylinder 12 has a guide post that slides inside, and the other end of the guide post is fixedly connected to the base plate 2. This structure allows the cylinder 12 to push the base plate 2 downward when it is running, thereby causing the shovel base 21 to move downward.

[0021] Furthermore, the two sides of the shovel base 21 are inclined, and the straight surface 22 is located at the bottom of the inclined surface. At the same time, a long strip slider is fixed on the surface of the shovel base 21. The first main slide 23 and the second main slide 26 are provided with long strip grooves, which correspond to each other. The above structure allows the first main slide 23 and the second main slide 26 to slide on the inclined surface of the shovel base 21 when the shovel base 21 moves downward. At the same time, they will also move horizontally along the inclined surface towards the shovel base 21. The straight surface 22 is located at the bottom of the inclined surface of the shovel base 21, so that the straight surface 22 only restricts the auxiliary slide from moving towards the first main slide 23 and the second main slide 26 at the beginning. When the straight surface 22 completely detaches from the lowest surface of the auxiliary slide, the straight surface 22 no longer restricts the movement of the auxiliary slide. The auxiliary slide moves towards the shovel base 21 together with the main slide and follows the demolding.

[0022] Furthermore, the bottom of the first auxiliary slide 24, the second auxiliary slide 25, the third auxiliary slide 27, and the fourth auxiliary slide 28 are provided with a plane corresponding to the straight surface 22. The above structure allows the auxiliary slides to first move towards the main slide under the constraint of the straight surface 22, and then move towards the shovel base 21 together with the main slide. Multiple slides and multiple displacement directions enable one-time demolding.

[0023] Furthermore, two sets of T-shaped sliders are fixedly connected to the surfaces of the first auxiliary slide position 24, the second auxiliary slide position 25, the third auxiliary slide position 27, and the fourth auxiliary slide position 28. Two sets of sliding grooves are opened on the surfaces of the first main slide position 23 and the second main slide position 26, and the shape of the sliding grooves corresponds to the shape of the T-shaped sliders.

[0024] Working principle: During demolding, the hydraulic cylinder 12 starts operating and pushes the base plate 2 downward through the guide pillar. Since the shovel base 21 is fixed on the base plate 2, the shovel base 21 also moves downward simultaneously. The slider on the inclined surface of the shovel base 21 cooperates with the sliding grooves on the first main slide 23 and the second main slide 26, causing the first main slide 23 and the second main slide 26 to move towards the shovel base 21. At the same time, since the straight surface 22 is located at the lower end of the inclined surface of the shovel base 21, the straight surface 22 will restrict the first auxiliary slide 24, the second auxiliary slide 25, and the third auxiliary slide. The positions of auxiliary slides such as position 27 and fourth auxiliary slide 28 allow them to move only towards the first main slide 23 and the second main slide 26, respectively. When the straight surface 22 moves downward and completely separates from the lowest surface of the auxiliary slide, the straight surface 22 loses its restriction on the auxiliary slide. The auxiliary slide moves along with the first main slide 23 and the second main slide 26 towards the shovel base 21 and demolds, thus achieving one-time demolding. After demolding, the base plate 2 drives the shovel base 21 to reset, and the shovel base 21 drives the main slide and auxiliary slide to reset, repeating the cycle.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
