Description

Technical Field

[0001] This utility model relates to the field of injection molding demolding technology, and in particular to a slanted demolding mechanism. Background Technology

[0002] Injection molding, as a highly efficient and flexible industrial product manufacturing method, has become one of the core processes in modern industrial manufacturing. With the diversification of demands for automotive accessory products, some product assembly modules and panels feature non-right-angle designs, making it impossible for traditional ejector mechanisms to directly demold via vertical ejection. For such structures, current solutions require first molding the approximate outline of the assembly module during the injection molding stage, followed by subsequent machining using CNC machine tools to meet product requirements. However, this approach not only increases production costs but also extends the product manufacturing cycle. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a slanted demolding mechanism that can demold assembly modules on a product.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a slanted ejection mechanism including a top block and a core; the top block is provided with a guide hole, the extension direction of the guide hole is at an acute angle to the horizontal plane; the core includes a core puller that is slidably disposed in the guide hole.

[0005] Furthermore, the top block is provided with a push rod, and the core puller is provided with an elongated hole along its own length direction, through which the push rod passes;

[0006] During injection molding, the ejector pin is located at one end of the elongated hole near the bottom of the core-pulling mechanism.

[0007] Furthermore, the core also includes a base, the core puller is disposed on the base, the top block is provided with an elastic element, and one end of the elastic element is connected to the base;

[0008] During demolding, the elastic element applies a vertically downward force to the base.

[0009] Furthermore, the top block is provided with a guide block, the guide block having a first inclined surface that abuts against the base, the first inclined surface being parallel to the extension direction of the guide through hole.

[0010] Furthermore, the base is provided with a second inclined surface that abuts against the first inclined surface, and the second inclined surface is parallel to the extension direction of the guide hole.

[0011] Furthermore, the top block is provided with a first mounting groove for installing the elastic element, and the top block is provided with a second mounting groove for installing the base.

[0012] Furthermore, the elastic element is a compression or elastic plunger.

[0013] Furthermore, the top block is provided with a top shaft, the axis of which is perpendicular to the horizontal plane.

[0014] The beneficial effects of this invention are as follows: By adding a guide hole to the top block, the core-pulling mechanism for the injection molding assembly module is slidably positioned within the guide hole. This allows the core-pulling mechanism to separate from the assembly module along the guide hole during demolding, while the top block vertically ejects the product, thus avoiding secondary processing.

[0025] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0026] Please refer to Figures 1 to 4As shown, the present invention provides a slanted ejection mechanism, including a top block 1 and a core 2; the top block 1 is provided with a guide hole 11, the extension direction of the guide hole 11 is at an acute angle to the horizontal plane; the core 2 includes a core-pulling mechanism 21 slidably disposed in the guide hole 11.

[0027] Working principle: A guide hole 11 is added to the top block 1, and the core puller 21 for injection molding assembly module 41 is slidably placed in the guide hole 11. During the demolding process, while the top block 1 vertically ejects the product 4, the core puller 21 separates from the assembly module 41 along the guide hole 11, avoiding secondary processing.

[0028] It is worth noting that the angle between the guide hole 11 and the horizontal plane is determined by the design angle of the assembly module 41 on product 4. For example, if the angle between the assembly module 41 and the horizontal plane is 87°, then the angle between the guide hole 11 and the horizontal plane is also 87°.

[0029] In some implementations, please refer to Figures 2 to 4 As shown, the top block 1 is provided with a push rod 12, and the core puller 21 is provided with an elongated hole 3 along its own length direction. The push rod 12 passes through the elongated hole 3. During injection molding, the push rod 12 is located at the end of the elongated hole 3 near the bottom of the core puller 21. With the cooperation of the push rod 12 and the elongated hole 3, after the top block 1 lifts the product 4 to complete demolding, the push rod 12 will lift the core puller 21 so that the core puller 21 and the push rod 12 move synchronously, preventing the core puller 21 from separating from the top block 1, so as to facilitate subsequent repositioning.

[0030] In some implementations, please refer to Figure 3 and Figure 4 As shown, the core 2 also includes a base 22, the core puller 21 is disposed on the base 22, and the top block 1 is provided with an elastic element 13, one end of which is connected to the base 22. During demolding, the elastic element 13 applies a vertically downward force to the base 22. By using the elastic element 13 to apply a vertically downward force to the base 22, relative displacement between the top block 1 and the core 2 is ensured during demolding.

[0031] Preferably, the elastic element 13 is a compression or elastic plunger. Of course, the elastic element 13 can also be other devices such as a nitrogen spring that can provide elastic force to the base 22.

[0032] In some implementations, please refer to Figure 5 As shown, the top block 1 is provided with a guide block 14, which has a first inclined surface 141 that abuts against the base 22. The first inclined surface 141 is parallel to the extending direction of the guide through hole 11. The first inclined surface 141 on the guide block 14 is used to further ensure the moving direction of the core puller 21.

[0033] It is worth noting that the base 22 is provided with a second inclined surface 221 that abuts against the first inclined surface 141, and the second inclined surface 221 is parallel to the extending direction of the guide hole 11. The first inclined surface 141 and the second inclined surface 221 enable the core 2 to move more smoothly on the top block 1.

[0034] In some implementations, please refer to Figure 3 As shown, the top block 1 is provided with a first mounting groove 15 for mounting the elastic element 13, and a second mounting groove 16 for mounting the base 22. The first mounting groove 15 and the second mounting groove 16 are used to allow the core 2 to be embedded in the top block 1, thereby reducing the height of the injection mold.

[0035] In some embodiments, the top block 1 is provided with a top shaft 17, the axis of which is perpendicular to the horizontal plane. The top block 1 is moved vertically in the injection mold by driving the top shaft 17.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
