Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically a deformation-resistant lateral core-pulling injection mold structure. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding include high production speed and efficiency, automated operation, a wide variety of designs and shapes (from simple to complex), and sizes ranging from large to small. It also produces dimensionally accurate products, facilitates product updates and replacements, and can create complex shapes. Injection molding is suitable for mass production and molding processes involving complex shapes.

[0003] A prior art patent application (application number 202422365164.6) describes a deformation-resistant, high-efficiency side-pulling injection mold structure, comprising: a base plate, a lower mold mounted on the upper side of the base plate, an upper mold fixedly connected to the output end of a hydraulic cylinder and cooperating with the lower mold, and a driving mechanism inside the lower mold. By setting a connecting rod and a push plate, when the driving mechanism drives the connecting rod and the connecting plate, the molded part is ejected under the action of the push block and the push plate, facilitating demolding of the injection mold and reducing damage to the molded part. Simultaneously, the core-pulling mechanism allows the mold core to freely shrink within the mold cavity without manual operation, improving the ease of use of the equipment. However, it is not convenient for unloading the product after injection molding within the mold cavity of the upper mold base. Utility Model Content

[0004] The purpose of this utility model is to provide a deformation-resistant side-pulling injection mold structure to solve the problem in the prior art that it is inconvenient to remove the product after injection molding in the upper mold cavity for unloading.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deformation-resistant lateral core-pulling injection mold structure, including a base plate, a lower mold base provided on the upper side of the base plate, a top plate provided on the upper side of the base plate via a column, an upper mold base provided on the lower side of the top plate via a hydraulic cylinder and the top plate, a limiting end plate and a lateral core-pulling plate slidably provided in the mold cavity inside the upper mold base, a transmission rod provided at one end of the lateral core-pulling plate via a support frame, a transverse push block provided at one end of the transmission rod via a spring and a limiting support, and push block pressing blocks provided on both sides of the top plate via upper brackets, with the push block pressing blocks positioned directly above the transverse push blocks.

[0006] Furthermore, the limiting end plate is configured as a rectangular plate, and the two sides of the limiting end plate are slidably disposed with respect to the inner wall of the mold cavity.

[0007] Furthermore, the limiting end plate and the side core-pulling plate are symmetrically arranged about the upper mold base, and sealing gaskets are provided on both sides of the limiting end plate.

[0008] Furthermore, the upper mold base has limiting sliding holes on both sides, and the side core-pulling plates are slidably set with limiting sliding holes via limiting sliders.

[0009] Furthermore, the limiting support is fixedly welded to the outer wall of the upper mold base, and the transmission rod is slidably disposed with respect to the limiting support.

[0010] Furthermore, the transverse push block is configured as a trapezoidal block, and the spring is sleeved on the outside of the transmission rod between the limiting support and the transverse push block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model features a limiting end plate and a side core-pulling plate that slide laterally within the mold cavity of the upper mold base. When the upper mold base is moved upward by the hydraulic cylinder, the lateral push blocks on both sides of the upper mold base touch the push block extrusion block. Under the extrusion of the push block extrusion block, the lateral push block, the limiting end plate, and the side core-pulling plate move laterally to the outside of the upper mold base, which facilitates the removal of the product that has been injection molded in the mold cavity of the upper mold base from the limiting end plate for unloading.

[0013] 2. This utility model has limiting sliding holes on both sides of the upper mold base, and the side core pulling plate is slidably set with limiting sliders and limiting sliding holes on both sides, which is used to guide the sliding during the lateral adjustment of the side core pulling plate, which helps to improve the stability of the lateral adjustment of the side core pulling plate and the limiting end plate.

[0014] 3. In this utility model, a transverse push block is elastically slidably provided at one end of the transmission rod through a spring and a limiting support. The spring is sleeved on the outside of the transmission rod between the limiting support and the transverse push block, so that when the push block does not press the transverse push block, the transverse push block can be transversely moved and reset under the action of the spring, in preparation for the next demolding.

[0020] 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.

[0021] Please see Figure 1 , Figure 2 , Figure 3 In this embodiment of the present invention, a deformation-resistant lateral core-pulling injection mold structure includes a base plate 1, a lower mold base 2 on the upper side of the base plate 1, a top plate 5 on the upper side of the base plate 1 via a column 6, and an upper mold base 3 on the lower side of the top plate 5 via a hydraulic cylinder 7 and a moving template 4. One end of the hydraulic cylinder 7 is connected to an oil storage tank via an oil supply pipe and a water pump. A limiting end plate 16 and a lateral core-pulling plate 8 are laterally slidably arranged in the mold cavity 17 inside the upper mold base 3. One end of the lateral core-pulling plate 8 is provided with a transmission rod 10 via a support frame 9. One end of the transmission rod 10 is elastically slidably provided with a transverse push block 12 via a spring 15 and a limiting support 11. The support 11 is fixedly welded to the outer wall of the upper mold base 3, and the transmission rod 10 is slidably set with the limiting support 11. The top plate 5 is provided with push blocks and extrusion blocks 14 on both sides through the upper bracket 13, and the push blocks and extrusion blocks 14 are located directly above the transverse push blocks 12. When the hydraulic cylinder 7 drives the upper mold base 3 to move upward, the transverse push blocks 12 on both sides of the upper mold base 3 touch the push blocks and extrusion blocks 14. Under the extrusion of the push blocks and extrusion blocks 14, the transverse push blocks 12, the limiting end plate 16 and the side core-pulling plate 8 move laterally to the outside of the upper mold base 3, so that the product that has been injected into the mold cavity 17 in the upper mold base 3 can be removed from the limiting end plate 16 for unloading.

[0022] like Figure 2 and Figure 3 As shown, the limiting end plate 16 is also set as a rectangular plate, and the two sides of the limiting end plate 16 are slidably arranged with the inner wall of the mold cavity 17. The limiting end plate 16 and the side core pulling plate 8 are symmetrically arranged about the upper mold base 3, and the two sides of the limiting end plate 16 are provided with sealing gaskets to improve the sealing performance of the sliding connection between the limiting end plate 16 and the inner wall of the mold cavity 17.

[0023] like Figure 1 and Figure 2As shown, in order to improve the stability of the lateral core-pulling plate 8 and the limiting end plate 16 in the lateral movement adjustment, limiting sliding holes 18 are also provided on both sides of the upper mold base 3, and the lateral core-pulling plate 8 is slidably set with the limiting sliding holes 18 through the limiting sliders 19 on both sides, which is used to guide the lateral core-pulling plate 8 in the lateral movement adjustment, which is beneficial to improving the stability of the lateral core-pulling plate 8 and the limiting end plate 16 in the lateral movement adjustment.

[0024] like Figure 2 and Figure 3 As shown, the transverse push block 12 is also configured as a trapezoidal block, and the spring 15 is sleeved on the outside of the transmission rod 10 between the limit support 11 and the transverse push block 12, so that when the push block pressing block 14 does not press the transverse push block 12, the transverse push block 12 can be transversely moved and reset under the action of the spring 15, in preparation for the next demolding.

[0025] The working principle and usage process of this utility model are as follows: During use, a limiting end plate 16 and a side core-pulling plate 8 are slidably arranged in the mold cavity 17 inside the upper mold base 3. A transmission rod 10 at one end of the side core-pulling plate 8 is elastically slidably provided with a transverse push block 12 through a spring 15 and a limiting support 11. When the hydraulic cylinder 7 drives the upper mold base 3 to move upward, the transverse push blocks 12 on both sides of the upper mold base 3 touch the push block extrusion block 14. Under the extrusion of the push block extrusion block 14, the transverse push block 12, the limiting end plate 16 and the side core-pulling plate 8 move laterally to the outside of the upper mold base 3, so that the product that has been injected into the mold cavity 17 inside the upper mold base 3 can be removed from the limiting end plate 16 for unloading.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
