Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold technology, and in particular to a front mold demolding mechanism for a complex porous structure product. Background Technology
[0002] Existing mold designs have flaws in the injection molding process, especially when dealing with products with complex porous structures and deep ribs. When the ribs are located in the front mold, the contact area between the product and the mold's A-plate is large, which easily leads to film sticking, increases friction during demolding, and causes the product to tear or be punctured by ejector pins during demolding, affecting product yield and production efficiency.
[0003] Furthermore, for products that are too small in size, the spring inserts in the existing demolding mechanism are prone to heat damage and deformation and are not durable, which further increases production costs and difficulty.
[0004] Moreover, existing molds need to fully consider whether a complex demolding structure is required during the design phase, and once the mold design is completed, it becomes very difficult to add a demolding structure later.
[0005] In view of the above, this utility model is hereby proposed. Utility Model Content
[0006] The purpose of this utility model is to provide a front mold demolding mechanism for products with complex porous structures, to solve the defects in existing mold designs, especially when processing products with complex porous structures and deep ribs. When the ribs are located in the front mold, the contact area between the product and the mold is large, which easily leads to film sticking, increases friction during demolding, and causes the product to tear or be punctured by ejector pins, affecting the product yield and production efficiency. The various technical effects of the preferred technical solutions provided by this utility model are detailed below.
[0007] To achieve the above objectives, the present invention provides the following technical solution:
[0008] This utility model provides a front mold demolding mechanism for a complex porous structure product, including a front mold mechanism and a spring block insert. The front mold mechanism includes a front mold panel and an A plate. The A plate is provided with a cavity for accommodating the product. The spring block insert is connected to the front mold panel and is movably disposed in the cavity, and cooperates with the cavity to form the forming space of the product's ribs.
[0009] Preferably, the spring block insert is connected to the front mold panel via a limiting screw.
[0010] Preferably, the spring insert is provided with a water well, and a water-blocking plate is provided in the water well. The water-blocking plate divides the running well to form a water channel with the bottom connected, which is used to cool the spring insert.
[0011] Preferably, the spring insert includes a fixed section and a forming section arranged concentrically from top to bottom. The forming section has a plurality of first bone forming grooves corresponding to the bone positions of the product and corresponding to the second bone forming grooves in the cavity of the A plate. The fixed section is provided with a pin, which extends along an axial direction parallel to the fixed section to the forming section and corresponds to the bone forming grooves one by one.
[0012] Preferably, the upper end face of the fixed section is provided with multiple threaded holes, and the limiting screw passes through the front mold panel and is screwed into the threaded holes.
[0013] Preferably, the water well extends from the fixed section to the formed section.
[0014] Preferably, the cross-section of the insert is T-shaped, and a positioning groove is provided on the fixed section, the shape of which is adapted to the insert.
[0015] Preferably, a plurality of springs are provided between the front mold panel and the A plate.
[0016] The preferred technical solution of this utility model can also produce at least the following technical effects:
[0017] This invention effectively avoids the defects in existing mold designs, especially when processing products with complex porous structures and deep ribs. When the ribs are located in the front mold, the large contact area between the product and the mold easily leads to adhesion, increasing friction during demolding and causing the product to tear or be punctured by ejector pins, affecting product yield and production efficiency. This invention provides a front mold demolding mechanism for complex porous products, including a front mold mechanism and a spring insert. The front mold mechanism includes a front mold panel and an A-plate. The A-plate has a cavity for accommodating the product. The spring insert is connected to the front mold panel and is movably disposed within the cavity, cooperating with the cavity to form the molding space for the product's ribs. By adding a spring insert and movably disposing it within the cavity, this invention changes the contact method between the product and the A-plate. Because the spring insert detaches from the product first, the contact area and friction between the product and the A-plate are reduced, thus reducing adhesion and improving product yield and production efficiency.
[0018] Specifically, during injection molding, plastic is injected into the molding space formed by the cavity and spring inserts, creating the product's structure and overall form. Once the product has cured, the front mold panel separates from the A-plate. Because the spring inserts are connected to the front mold panel, they can move with it. This allows the spring inserts to separate from the product before the cavity during demolding, altering the contact pattern between the product and the A-plate and reducing the contact area and friction between them.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0026] like Figures 1-3As shown, this utility model provides a front mold demolding mechanism for a complex porous structure product, including a front mold mechanism 1 and a spring block insert 2. The front mold mechanism 1 includes a front mold panel 11 and an A plate 12. The A plate 12 is provided with a cavity 121 for accommodating the product. The spring block insert 2 is connected to the front mold panel 11 and is movably disposed in the cavity 121 and cooperates with the cavity 121 to form the forming space of the product's ribs.
[0027] By adding a spring insert 2 and movably setting it in the cavity 121, the contact method between the product and the A plate 12 is changed. Since the spring insert 2 detaches from the product first, the contact area and friction between the product and the A plate 12 are reduced, thereby reducing the occurrence of film sticking and improving the product yield and production efficiency.
[0028] Specifically, during the injection molding process, plastic is injected into the molding space formed by the cavity 121 and the spring insert 2, forming the product's core and overall structure. After the product solidifies, the front mold panel 11 separates from the A plate 12. Since the spring insert 2 is connected to the front mold panel 11, it can move with the front mold panel 11. This allows the spring insert 2 to separate from the product before the cavity 121 during demolding, changing the contact method between the product and the A plate 12, reducing the contact area and friction between the product and the A plate 12, thereby reducing the occurrence of film sticking and improving product yield and production efficiency.
[0029] As an optional implementation, the spring insert 2 is connected to the front mold panel 11 by the limiting screw 5.
[0030] This design improves the stability of the connection between the spring insert 2 and the front mold panel 11.
[0031] As an optional implementation, the spring insert 2 is provided with a water well 23, and a water-blocking plate 7 is provided inside the water well 23. The water-blocking plate 7 divides the running well to form a water channel with the bottom connected, which is used to cool the spring insert 2.
[0032] Furthermore, the water well 23 extends along the axial direction of the spring block insert 2, so that the spring block insert 2 is cooled uniformly in the axial direction.
[0033] The water baffle 7 extends the flow path and time of cooling water in the water well 23, improves cooling efficiency, prevents deformation or damage caused by excessive temperature, and improves the durability of the spring block insert 2.
[0034] As an optional implementation, the spring insert 2 includes a fixed section 21 and a molding section 22 arranged concentrically from top to bottom. The molding section 22 has a plurality of first bone position molding grooves 221 that correspond to the bone positions of the product. The fixed section 21 is provided with insert pins 3, which extend along an axial direction parallel to the fixed section 21 to the molding section 22 and are arranged in correspondence with the bone position molding grooves.
[0035] Furthermore, the shape of the molding segment 22 is adapted to the shape of the product's rib structure. For example... Figure 1 As shown, the forming section 22 is a cylindrical structure, and the first rib forming groove 221 is arranged on the outer wall along its circumference. The function of the first rib forming groove 221 is to accurately form the complex, multiple and circumferentially arranged rib structure of the product when the mold is closed.
[0036] like Figure 3 As shown, a second bone-position forming groove 1211 is provided on the inner wall of the bone-position structure cavity within the cavity 121 of plate A 12. The forming segment 22 is inserted into the bone-position structure cavity, and the first bone-position forming groove 221 and the second bone-position forming groove 1211 are arranged in a one-to-one correspondence. Since the first bone-position forming groove 221 and the second bone-position forming groove 1211 within the cavity 121 of plate A 12 are arranged in a corresponding manner, when the mold is closed, the first bone-position forming groove 221 and the second bone-position forming groove 1211 together form the bone structure of the product, enabling the precise formation of a larger number and more complex bone structures of the product in the mold.
[0037] The function of the fixing section 21 is to connect the front mold panel 11 and the fixing pin 3. The function of the fixing pin 3 is to guide the flow of plastic during the injection molding process.
[0038] As an optional implementation, the upper end face of the fixed section 21 is provided with multiple threaded holes, and the limiting screw 5 passes through the front mold panel 11 and is screwed into the threaded holes.
[0039] Furthermore, there are two threaded holes, which are arranged symmetrically. The limiting screw 5 passes through the front mold panel 11 and is screwed into the threaded hole, so that the spring block insert 2 is securely installed on the front mold panel 11.
[0040] As an optional implementation, the water well 23 extends from the fixed section 21 to the forming section 22.
[0041] Furthermore, the inlet of the water-carrying well 23 is located at the center of the fixed section 21 and is connected to the cooling water pipe 4. A pump body is installed on the cooling water pipe 4 to provide the driving force for the flow of cooling water. The water-separating plate 7 divides the water-carrying well 23 into two symmetrical cooling areas, and the two cooling areas are connected at the bottom.
[0042] Cooling water enters a cooling zone from top to bottom through the inlet section of cooling water pipe 4, then smoothly enters another cooling zone, and flows from bottom to top into the outlet section of cooling water pipe 4 in the other cooling zone, increasing the flow path of cooling water and allowing more time for heat exchange with the spring insert 2 in the water well 23, thereby improving cooling efficiency.
[0043] As an optional implementation, the cross-section of the insert 3 is T-shaped, and a positioning groove 211 is provided on the fixing section 21, the shape of which is adapted to the insert 3.
[0044] Furthermore, the positioning groove 211 has a T-shaped cross-section, which matches the insert pin 3, and the larger end of the positioning groove 211 is far away from the cavity 121. This design improves the stability of the connection between the insert pin 3 and the spring insert 2, and prevents the insert pin 3 from shifting or falling off during the injection molding process.
[0045] As an optional implementation, a plurality of springs 6 are provided between the front mold panel 11 and the A plate 12.
[0046] Furthermore, there are four springs 6, which are respectively located at the corners of plate A 12.
[0047] The function of spring 6 is that during the opening process of the front mold mechanism 1, the spring 6, which is in a compressed state, releases its stored elastic potential energy, drives the front mold panel 11 to move the spring block insert 2, so that the spring block insert 2 can be smoothly separated from the product.
