Description

Technical Field

[0001] This utility model relates to the field of demolding technology, specifically a pneumatically assisted rapid demolding mold. Background Technology

[0002] Molds are indispensable process equipment in industrial production, widely used in numerous fields such as automobiles, electronics, home appliances, and aerospace. They enable mass production of products, ensure dimensional accuracy and surface quality, improve production efficiency, and reduce production costs. In various mold forming processes, such as injection molding, die casting, and stamping, demolding is a critical step that directly affects product quality and production efficiency.

[0003] Currently, some small businesses or those with small production scales still use manual demolding. This method is not only labor-intensive but also extremely inefficient, failing to meet the needs of large-scale industrial production. Furthermore, manual demolding suffers from poor consistency, easily leading to inconsistent product quality due to human error. Therefore, a pneumatically assisted rapid demolding mold is proposed to address these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a pneumatically assisted rapid demolding mold, which has the advantages of using a pneumatic motor to drive the lifting component to achieve rapid demolding, easy disassembly and maintenance of each mold component, and the use of a cylinder to achieve the pressing action. It solves the problems of low demolding efficiency, such as long demolding time, easy failure during demolding process, and mismatch of production cycle in the current stage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pneumatically assisted rapid demolding mold, including a base, a mold body movably mounted on the upper surface of the base, a pneumatic motor fixedly mounted on the front of the mold body via a mounting bracket, the base including a base plate and support brackets fixedly mounted on both sides of the upper surface of the base plate, and a lifting assembly rotatably mounted on the upper surface of the base plate via a hole in the middle and a bearing.

[0006] The top of the lifting assembly extends into the mold body and is threadedly fitted with a release module.

[0007] The mold body is assembled from bottom to top with a support mold, a bottom mold, a middle mold, a top mold, and a pressure mold. The bottom mold has a groove that matches the size of the demolding mold. The middle mold and the top mold have plastic cavities of the same size on opposite sides. The cross-sectional size of the plastic cavity matches the cross-sectional size of the demolding mold.

[0008] Preferably, cylinders are fixedly installed on both sides of the support frame, the top of the cylinders are fixedly connected to the pressing mold, and a through rod is fixedly installed on the support frame.

[0009] In the design, cylinders are fixedly installed on both sides of the support frame, with the tops of the cylinders fixedly connected to the mold, achieving precise driving of the mold. This allows the cylinders to stably and powerfully drive the mold downwards during the product molding stage, promoting tight fitting of all mold components, ensuring efficient completion of the mold closing action, and providing a stable pressure environment for product molding. Simultaneously, a through rod is fixedly installed on the support frame, serving a positioning and guiding function during mold assembly, ensuring the accuracy and stability of each mold component during installation, thereby improving the overall assembly precision of the mold.

[0010] Preferably, the lifting assembly includes a drive wheel, a second adjusting screw is welded to the top of the drive wheel, the second adjusting screw is threadedly connected to the release module, and the drive wheel is driven by a pneumatic motor via a drive belt.

[0011] In the design, by welding a second adjusting screw to the top of the lifting assembly and using a transmission belt to connect the transmission wheel to the pneumatic motor, the pneumatic motor efficiently transmits the lifting action. When the pneumatic motor starts, it quickly drives the transmission wheel to rotate, which in turn causes the second adjusting screw to rotate synchronously. Through its threaded connection with the demolding module, the demolding module is precisely and quickly pushed upwards, enabling rapid demolding of the product and greatly improving demolding efficiency.

[0012] Preferably, the upper end face of the support mold has first through holes at the four corners for the through rod to pass through, and a reserved hole in the middle of the upper end face of the support mold for the second adjusting screw to pass through. Positioning rods are welded and installed on the upper end face of the support mold in a rectangular array.

[0013] In the design, by opening first through holes at the four corners of the upper end face of the support mold for the passage of the through rods, precise positioning of the support mold during mold assembly is achieved, ensuring the accurate vertical positional relationship between the support mold and other components. Simultaneously, a reserved hole in the middle of the upper end face of the support mold for the passage of the second adjusting screw provides a channel for the normal operation of the lifting component, ensuring that the demolding module can smoothly pass through the support mold for lifting during demolding. Furthermore, positioning rods are welded in a rectangular array on the upper end face of the support mold, playing a positioning role during the subsequent installation of components such as the bottom mold and middle mold, enabling rapid and accurate assembly of each component and improving mold assembly efficiency.

[0014] Preferably, the upper end face of the bottom mold has a second through hole at each of the four corners for the through rod to pass through, and the upper end face of the bottom mold has a first positioning hole in a rectangular array for the positioning rod to pass through.

[0015] In the design, by opening second through holes at the four corners of the upper end face of the bottom mold for the through rods to pass through, the vertical positioning of the bottom mold in the overall mold structure is achieved, ensuring the relative positional accuracy of the bottom mold and other components. The upper end face of the bottom mold has a rectangular array of first positioning holes for the positioning rods to pass through, which allows the bottom mold to be accurately installed above the support mold. The cooperation between the positioning rods and the positioning holes enhances the stability and accuracy of the mold assembly, which is conducive to maintaining a stable mold structure during the product molding process.

[0016] Preferably, the upper end face of the middle mold is provided with third through holes at the four corners for the through rod to pass through, and the upper end face of the middle mold is provided with second positioning holes in a rectangular array for the positioning rod to pass through.

[0017] In the design, by opening third through holes at the four corners of the upper end face of the intermediate mold for the through rod to pass through, the intermediate mold is accurately installed along the through rod during mold assembly, ensuring the vertical positional accuracy of the intermediate mold. The upper end face of the intermediate mold has a rectangular array of second positioning holes for the positioning rod to pass through, allowing the intermediate mold to be accurately spliced ​​with the lower bottom mold and the upper top mold. This ensures the consistency of the position of each molding cavity after splicing, which is beneficial for the uniform molding of the product within the molding cavity and improves the molding quality of the product.

[0018] Preferably, a fourth through hole is provided at each of the four corners of the upper end face of the top mold for the through rod to pass through.

[0019] In the design, by opening a fourth through hole at the four corners of the upper end face of the top mold for the through rod to pass through, the accurate installation and positioning of the top mold during the mold assembly process is achieved. This ensures the accurate positional relationship between the top mold and other components in the vertical direction, enabling the top mold to closely cooperate with the middle mold to form a stable plastic cavity structure and provide a reliable mold space for product molding.

[0020] Preferably, the upper end face of the die is provided with a fifth through hole at each of the four corners for the through rod to pass through, and a screw hole is provided in the upper end face of the die for threaded installation of a first adjusting screw. The bottom of the first adjusting screw contacts the upper end face of the top die but is not fixedly connected.

[0021] In the design, by opening fifth through holes at the four corners of the upper end face of the die for the through rod to pass through, accurate installation and positioning of the die during mold assembly is achieved, ensuring the vertical positional accuracy of the die relative to other components. This allows the die to precisely apply pressure to the lower mold assembly to complete the mold closing action. A screw hole is provided on the upper end face of the die, and a first adjusting screw is movably inserted therein. The bottom of the first adjusting screw contacts the upper end face of the top die but is not fixedly connected, enabling adjustable pressure on the top die. In actual production, the pressure of the die on the top die and the entire mold assembly can be adjusted by changing the screw depth of the first adjusting screw according to the specific molding requirements of the product. This improves the versatility and adaptability of the mold, enabling it to meet the molding process requirements of different products.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] This invention achieves rapid demolding by fixing a pneumatic motor to the front of the mold body using a mounting bracket. The pneumatic motor is connected to the drive wheel of the lifting assembly via a transmission belt. A second adjusting screw welded to the top of the drive wheel is threadedly connected to the demolding module. This allows the pneumatic motor to drive the lifting assembly for rapid demolding. When the pneumatic motor starts, it quickly drives the lifting assembly, rapidly pushing the demolding module to eject the product from the molding cavity, significantly shortening the demolding time and solving the problem of long demolding times.

[0024] This invention designs the mold body as a support mold, bottom mold, middle mold, top mold, and pressure mold that are assembled from bottom to top. Each component is installed via positioning rods and positioning holes, and through rods and corresponding through holes, achieving a design that facilitates easy disassembly and maintenance. When maintenance or replacement of parts is required, disassembly can be performed easily in the reverse order of assembly, reducing maintenance difficulty and cost.

[0025] This invention achieves the effect of pressing the mold by fixing cylinders to both sides of a support frame and connecting the tops of the cylinders to the mold. During the product molding stage, the cylinders can precisely and stably drive the mold downwards, ensuring that all mold components fit tightly together and guaranteeing efficient mold closing. Simultaneously, the rapid and stable mold closing and demolding actions allow for better matching of the mold's production cycle with other production stages, solving the problem of mismatched production cycles. Furthermore, the stable mold closing and rapid demolding reduce malfunctions caused by uncoordinated actions during demolding, such as product sticking to the mold or jamming of the demolding mechanism, thus resolving the problem of frequent malfunctions during demolding.

[0035] The mold body 3 is assembled from bottom to top with a support mold 31, a bottom mold 32, a middle mold 33, a top mold 34 and a pressure mold 35. The bottom mold 32 has a groove 322 that matches the size of the demolding mold 6. The middle mold 33 and the top mold 34 have plastic cavities 333 of the same size on opposite sides. The cross-sectional dimensions of the plastic cavity 333 match the cross-sectional dimensions of the demolding mold 6.

[0036] Specifically, by fixing a pneumatic motor 4 to the front of the mold body 3 using a mounting bracket 42, and connecting the pneumatic motor 4 to the transmission wheel 51 of the lifting assembly 5 via a transmission belt 41, and by threading the second adjusting screw 52 welded to the top of the transmission wheel 51 to the demolding module 6, the pneumatic motor 4 drives the lifting assembly 5 to achieve rapid demolding. When the pneumatic motor 4 starts, it can quickly drive the lifting assembly 5 to operate, rapidly pushing the demolding module 6 to eject the product from the molding cavity 333, greatly shortening the demolding time and solving the problem of long demolding time.

[0037] By designing the mold body 3 as a support mold 31, bottom mold 32, middle mold 33, top mold 34, and pressure mold 35 that are assembled from bottom to top, and by using positioning rods 312 with positioning holes and through rods 13 with corresponding through holes for installation, the mold components are designed to be easy to disassemble and maintain.

At the same time, the fast and stable mold closing and demolding actions allow the mold's production cycle to better match with other production stages, solving the problem of mismatched production cycles. In addition, the stable mold closing action and fast demolding reduce malfunctions caused by uncoordinated actions during demolding, such as product sticking to the mold or jamming of the demolding mechanism, solving the problem of easy failures during the demolding process.

Simultaneously, a through rod 13 is fixedly installed on the support frame 12, serving a positioning and guiding function during mold assembly, ensuring the accuracy and stability of each mold component during installation, thereby improving the overall assembly precision of the mold.

[0042] Furthermore, the lifting assembly 5 includes a drive wheel 51, and a second adjusting screw 52 is welded to the top of the drive wheel 51. The second adjusting screw 52 is threadedly connected to the release module 6. The drive wheel 51 is driven by the pneumatic motor 4 via a drive belt 41.

[0043] In the design, by welding a second adjusting screw 52 to the top of the transmission wheel 51 and using a transmission belt 41 to connect the transmission wheel 51 to the pneumatic motor 4, the pneumatic motor 4 efficiently transmits the lifting action. When the pneumatic motor 4 starts, it can quickly drive the transmission wheel 51 to rotate, thereby causing the second adjusting screw 52 to rotate synchronously. Through the threaded connection with the demolding module 6, it accurately and quickly pushes the demolding module 6 upward, realizing rapid demolding of the product and greatly improving demolding efficiency.

Simultaneously, a reserved hole 311 is opened in the middle of the upper end face of the support mold 31 for the second adjusting screw 52 to pass through, providing a channel for the normal operation of the lifting component 5 and ensuring that the demolding module 6 can smoothly pass through the support mold 31 for lifting during the demolding process. Furthermore, positioning rods 312 are welded in a rectangular array on the upper end face of the support mold 31, which play a positioning role during the subsequent installation of components such as the bottom mold 32 and the middle mold 33, enabling the components to be quickly and accurately assembled, thus improving mold assembly efficiency.

[0053] Furthermore, the upper end face of the die 35 is provided with a fifth through hole 351 at each of the four corners for the through rod 13 to pass through. The upper end face of the die 35 is provided with a screw hole and a first adjusting screw 352 is threadedly installed. The bottom of the first adjusting screw 352 contacts the upper end face of the top die 34 but is not fixedly connected.

[0054] In the design, by opening fifth through holes 351 at the four corners of the upper end face of the pressure mold 35 for the passage of the through rod 13, the accurate installation and positioning of the pressure mold 35 during mold assembly is achieved. This ensures the positional accuracy of the pressure mold 35 in the vertical direction compared to other components, enabling the pressure mold 35 to accurately apply pressure to the lower mold assembly and complete the mold closing action. The upper end face of the pressure mold 35 has a screw hole with a first adjusting screw 352 movably inserted. The bottom of the first adjusting screw 352 contacts the upper end face of the top mold 34 but is not fixedly connected, achieving adjustable pressure on the top mold 34. In actual production, the pressure of the pressure mold 35 on the top mold 34 and the entire mold assembly can be adjusted by adjusting the screw depth of the first adjusting screw 352 according to the specific requirements of product molding.
