Description

Technical Field

[0001] This utility model relates to the field of zinc-aluminum alloy die-casting mold technology, specifically to an easy-to-install, reinforced, and resistant-to-fall-off insert device. Background Technology

[0002] Currently, as people's living standards improve, their pursuit of product performance also increases. The increasing complexity of product structures leads to higher manufacturing costs. In addition, China's labor costs are rising year by year, making it difficult for companies to improve their profit margins and significantly increasing the pressure on enterprises. For the current high-pressure casting industry market, reducing casting costs and improving casting efficiency while ensuring the quality requirements of castings are the primary problems that casting companies need to solve. For mold production, inserts are also one of the most important fixing components.

[0003] In existing technologies, although inserts can fix products, double-headed knitting without inserts can easily lead to the insert being reversed during installation due to operator error. Furthermore, the lack of a reinforcing structure results in poor resistance to thread torque and fatigue, making it difficult to promote and use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an easy-to-install, reinforced, and non-detachable insert device. It can effectively solve the problems in the prior art where double-headed knitting without insert design is prone to causing the insert to be reversed due to operator error during installation, and the lack of a reinforcing structure makes it easy to have poor resistance to thread torque and fatigue resistance, thus making it inconvenient to promote and use.

[0005] The technical solution adopted by this utility model is: an easy-to-install reinforced and resistant-to-fall-off insert device, including a fixed mold, a moving mold and a mold slider, wherein an insert assembly is provided between the mold sliders, and a transition groove is provided at one end of the mold slider near the insert assembly; The insert assembly includes a post and a nest, which are fixedly installed. The post has a knurled groove at the end away from the nest, and the end of the post away from the nest is beveled.

[0006] Preferably, a connecting groove is provided at the inner edge of the nest, and the nest is fixedly installed with the embedded post through the connecting groove.

[0007] Through the above technical solution, the design of the connecting groove enables the nest and the embedded column to be quickly positioned when connected, thus preventing displacement when the two are welded together and preventing the embedded column and the nest from separating during the die casting process. They can jointly bear the pressure when the aluminum liquid is wrapped and the torque during later use.

[0008] Preferably, the length of the insert is longer than the length of the nest, and the diameter of the nest is greater than the diameter of the insert.

[0009] The above technical solution allows for easier handling by operators, and the thicker nesting reinforcement at the root reduces bending under stress, simplifies the installation process, improves production efficiency, enhances the bond between the insert and the casting, and improves resistance to detachment.

[0010] Preferably, there are two identical knurled grooves and bevels, and the two knurled grooves and bevels are symmetrically distributed about the center line of the embedded post.

[0011] The above technical solution allows the molten aluminum to solidify through knurling grooves and form a mechanical engagement with the insert, which can significantly improve torsional resistance and fatigue resistance. In addition, the combination of the beveled angle and the beveled surface of the transition groove reduces the resistance of the insert assembly when it is installed into the mold slider. The double-end knurling design avoids the risk of reverse installation, and the beveled angle combined with the transition groove improves installation efficiency.

[0012] Preferably, a hydraulic cylinder is fixedly installed at one end of the fixed mold, and a mold slider is fixedly installed at the output end of the hydraulic cylinder.

[0013] With the above technical solution, when installing the insert, the hydraulic cylinder opens the mold slider to expose the installation position. After the insert assembly is placed in, the hydraulic cylinder pushes the slider to close, positioning the insert assembly in the cavity. After die casting is completed, the hydraulic cylinder resets the mold slider, causing the insert assembly to separate from the mold slider.

[0014] Preferably, a fixing plate is provided at the end of the moving mold away from the fixed mold, and an ejector pin is provided at the end of the fixing plate close to the moving mold.

[0015] Through the above technical solution, after the die casting solidifies, the ejector pin moves axially under the drive of the fixed plate, and applies an ejection force evenly to the bottom of the casting, so that the insert assembly is separated from the cavity of the fixed mold and the moving mold. This can avoid the deformation of the casting or the loosening of the insert due to uneven force, protect the joint structure between the insert and the casting, and maintain the torsional performance.

[0016] Preferably, a mold material cylinder is fixedly installed at the end of the fixed mold away from the moving mold, and a transition groove is provided at one end of the mold slider, the transition groove being adapted to the insert assembly.

[0017] Through the above technical solution, the small material cylinder of the mold injects molten aluminum into the cavity, so that the molten aluminum fully covers the knurled groove of the insert assembly. The chamfer of the transition groove matches the bevel of the insert post, reducing the installation resistance and enabling the insert to be quickly placed in place.

[0018] Compared with the prior art, this utility model provides an easy-to-install, reinforced, and resistant-to-fall-off insert device, which has the following advantages: This easy-to-install, reinforced, and resistant insert device features a double-ended knurled design, eliminating the need for installers to install the insert backwards. Furthermore, the large chamfer on the mold and the appropriately extended insert length further facilitate installation and demolding, reducing mold deformation. This structure can be readily applied to molded products, extending mold lifespan and ensuring production demolding stability. It also enhances the installation of the insert, improving thread torque and fatigue resistance. Attached Figure Description

[0021] 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.

[0022] Example 1: As Figure 1-6 As shown, the present invention provides an easy-to-install reinforced and resistant-to-fall-off insert device, including a fixed mold 1, a moving mold 2 and a mold slider 4, an insert assembly 5 is provided between the mold sliders 4, and a transition groove 6 is provided at one end of the mold slider 4 near the insert assembly 5; The insert assembly 5 includes a post 501 and a nest 502, which are fixedly installed. The end of the post 501 away from the nest 502 is provided with a knurled groove 504, and the end of the post 501 away from the nest 502 is beveled at an angle 505.

[0023] Specifically, a connecting groove 503 is provided at the inner edge of the nest 502. The nest 502 is fixedly installed with the embedded post 501 through the connecting groove 503. The advantage is that the design of the connecting groove 503 can play a role in quick positioning when the nest 502 and the embedded post 501 are connected. This avoids displacement when the two are welded together, and prevents the embedded post 501 and the nest 502 from separating during the die casting process. They can jointly bear the pressure when the aluminum liquid is wrapped and the torque during later use.

[0024] Specifically, the length of the insert 501 is longer than the length of the nest 502, and the diameter of the nest 502 is larger than the diameter of the insert 501. The advantage is that the longer insert 501 is easier for operators to handle, and the thicker nest 502 strengthens the root support, reduces bending under stress, simplifies the installation process, improves production efficiency, enhances the bonding force between the insert and the casting, and improves the resistance to falling off.

[0025] Specifically, two identical knurled grooves 504 and bevels 505 are provided. The two knurled grooves 504 and bevels 505 are symmetrically distributed about the center line of the insert 501. The advantage is that the knurled grooves 504 allow the molten aluminum to solidify and form a mechanical engagement with the insert 501, which can significantly improve torsional resistance and fatigue resistance. In addition, the bevels 505 and the bevels of the transition groove 6 are matched to reduce the resistance of the insert assembly 5 when it is installed into the mold slider 4. The double-end knurling design can avoid the risk of reverse installation, and the bevels 505 and the transition groove 6 can improve the installation efficiency.

[0026] Example 2: Figure 2-6 As shown, this is an improvement on the previous embodiment.

[0027] Specifically, a hydraulic cylinder 7 is fixedly installed at one end of the fixed mold 1, and a mold slider 4 is fixedly installed at the output end of the hydraulic cylinder 7. The advantage is that when installing the insert, the hydraulic cylinder 7 causes the mold slider 4 to open, exposing the installation position. After the insert assembly 5 is placed in, the hydraulic cylinder 7 pushes the slider to close, positioning the insert assembly 5 in the cavity. After die casting is completed, the hydraulic cylinder 7 causes the mold slider 4 to reset, disengaging the insert assembly 5 from the mold slider 4.

[0028] Specifically, a fixed plate 8 is provided at the end of the moving mold 2 away from the fixed mold 1, and an ejector pin 9 is provided at the end of the fixed plate 8 close to the moving mold 2. The advantage is that after the die casting solidifies, the ejector pin 9 moves axially under the drive of the fixed plate 8, and applies an ejection force evenly to the bottom of the casting, so that the insert assembly 5 is separated from the cavity of the fixed mold 1 and the moving mold 2. This can avoid the deformation of the casting or the loosening of the insert due to uneven force, protect the joint structure between the insert and the casting, and maintain the torsional performance.

[0029] Specifically, a mold small material cylinder 3 is fixedly installed at the end of the fixed mold 1 away from the moving mold 2, and a transition groove 6 is opened at one end of the mold slider 4. The transition groove 6 is adapted to the insert assembly 5. The advantage is that the mold small material cylinder 3 injects aluminum liquid into the cavity, so that the aluminum liquid fully covers the knurled groove 504 of the insert assembly 5. The chamfer of the transition groove 6 matches the bevel angle 505 of the insert post 501, reducing the installation resistance and allowing the insert to be quickly placed in place.

[0030] Working Principle: During use, the design of the connecting groove 503 allows for quick positioning when the nest 502 and the insert 501 are connected, preventing displacement during subsequent welding and avoiding separation of the insert 501 and nest 502 during die casting. They share the pressure of the molten aluminum and the torque during later use. The longer insert 501 is easier for operators to handle, and the thicker nest 502 reinforces the root support, reducing bending under stress. This simplifies the installation process, improves production efficiency, enhances the bond between the insert and the casting, and improves resistance to detachment. The knurled groove 504 allows the solidified molten aluminum to mechanically interlock with the insert 501, significantly improving torsional resistance and fatigue resistance. Furthermore, the bevel angle 505 and the inclined surface of the transition groove 6 reduce the resistance of the insert assembly 5 when it is inserted into the mold slider 4. The double-end knurling design... To avoid the risk of reverse installation and to improve installation efficiency with the bevel angle 505 and transition groove 6, when installing the insert, the hydraulic cylinder 7 opens the mold slider 4 to expose the installation position. After the insert assembly 5 is placed in, the hydraulic cylinder 7 pushes the slider to close, positioning the insert assembly 5 in the cavity. After die casting is completed, the hydraulic cylinder 7 resets the mold slider 4, causing the insert assembly 5 to separate from the mold slider 4. After the die casting solidifies, the ejector pin 9 moves axially under the drive of the fixed plate 8, uniformly applying ejection force to the bottom of the casting, separating the insert assembly 5 from the cavity of the fixed mold 1 and the moving mold 2. This avoids casting deformation or insert loosening due to uneven force, protects the bonding structure between the insert and the casting, and maintains torsional performance. The mold small material cylinder 3 injects molten aluminum into the cavity, allowing the molten aluminum to fully cover the knurled groove 504 of the insert assembly 5. The chamfer of the transition groove 6 matches the bevel angle 505 of the insert post 501, reducing installation resistance and allowing the insert to be quickly positioned.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
