Description

Technical Field

[0001] This utility model relates to molding equipment, and more specifically, to a mold that can be quickly assembled and disassembled. Background Technology

[0002] A single thermoforming mold is typically used to produce only one type of product. When a different product needs to be produced, a new mold must be fabricated, the original mold removed from the thermoforming machine, and the new mold installed. For example, thermoforming molds used to make plastic containers (such as plastic cups, boxes, and basins) commonly include vacuum forming molds (using vacuum to press the softened sheet against the inner surface of the mold cavity), positive pressure forming molds (using compressed air or steam pressure to press the softened sheet against the inner surface of the mold cavity), and combined vacuum and compressed air or steam pressure molds (using both vacuum and compressed air or steam pressure to press the softened sheet against the inner surface of the mold cavity). Therefore, a single thermoforming mold can only be used to produce one type of plastic container. When a different type of plastic container needs to be produced, a new thermoforming mold must be fabricated, the original mold removed from the thermoforming machine, and the new mold installed. Replacing the entire mold increases equipment costs, and the disassembly and installation process is cumbersome, increasing labor costs and reducing efficiency.

[0003] Existing molds generally include a mold mounting plate and at least one mold. Each mold is mounted on the upper surface of the mold mounting plate. Each mold has a mold cavity, which corresponds to the shape and size of the product. The shape and / or size of the mold cavity varies depending on the product requirements. The mold mounting plate (usually the lower mold plate in thermoforming molds) serves as a support platform for each mold and is typically connected or coordinated with a corresponding mechanism of the forming machine, such as the power output end of a lifting mechanism that controls the mold's lifting. In the case of a thermoforming mold, the mold is usually also equipped with a pressure ring. During thermoforming, the pressure ring presses the sheet material firmly against the solid portion surrounding the mold cavity. The mold typically has an exhaust channel, one end of which connects to the mold cavity, and the other end connects to a vacuum device (for vacuuming the inside of the mold cavity during negative pressure forming) or connects to the outside (for expelling air from the mold cavity during positive pressure forming). When a different product needs to be produced, each molding die can be removed from the molding die mounting plate, and a new molding die can be installed on the molding die mounting plate. Therefore, the molding die mounting plate is versatile, which reduces equipment costs to some extent. However, the current common practice is to fix each molding die to the molding die mounting plate using connectors (such as bolts). Fixing one molding die requires 3-4 connectors. When there are a large number of molding dies, the number of connectors is large, and each one must be disassembled, installed, and calibrated individually, which takes a lot of time, resulting in low work efficiency and a significant waste of production time. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a mold with a quick-disassembly and assembly molding die. This mold allows for rapid disassembly and assembly, enabling quick mold replacement and facilitating easy modification of the mold for the production of other products, thus saving costs and improving work efficiency. The technical solution adopted is as follows:

[0005] A mold with a quick-release molding die includes a molding die mounting plate and at least one molding die, each molding die being mounted on the upper surface of the molding die mounting plate. The mold is characterized in that: the molding die mounting plate is provided with at least one molding die clamping mechanism, and the bottom of the molding die is provided with clamping mounting holes at positions corresponding to the molding die clamping mechanism; the molding die clamping mechanism includes a clamping component position switching mechanism and at least one clamping component, the clamping component having a pressing part.

[0006] The clamping component position switching mechanism can switch the position of the clamping component, so that the clamping part of the clamping component can switch between the following two positions: in one position, the clamping part of the clamping component presses against the upper side of the solid part around the clamping mounting hole; in the other position, the clamping part of the clamping component moves away from the solid part around the clamping mounting hole and is within the range of the clamping mounting hole.

[0007] In this utility model, the clamping part of the clamping component is within the range of the clamping mounting hole, which means that with the upper surface of the molding mold mounting plate as the projection surface, the orthographic projection of the clamping part of the clamping component is within the clamping mounting hole.

[0008] The aforementioned quick-assembly mold can be equipped with various molding dies (different molding dies have different shapes and / or sizes of molding cavity), each molding die corresponding to a specific product. The molding die can be quickly changed through the cooperation between the molding die clamping mechanism and the clamping mounting holes and surrounding solid parts on the molding die. In the initial assembly stage, the clamping component position switching mechanism moves the clamping part away from the solid parts surrounding the clamping mounting holes. At this time, the clamping mounting holes on the molding die can be aligned and fitted, with the clamping part of the clamping component within the range of the clamping mounting holes. Subsequently, the clamping component position switching mechanism switches the position of the clamping component, pressing the clamping part against the upper side of the solid parts surrounding the clamping mounting holes, thereby pressing the molding die onto the molding die mounting plate and fixing its position. After all molding dies are installed, production can begin. When producing other products, the clamping component position switching mechanism switches the position of the clamping component, so that the clamping part of the clamping component moves away from the solid part around the clamping mounting hole and is within the range of the clamping mounting hole. At this time, the clamping part of the clamping component will not hinder the placement and removal of the molding die. The original molding die can be removed, and the clamping mounting hole on the new molding die can be aligned and fitted in. Subsequently, the clamping component position switching mechanism switches the position of the clamping component again, so that the clamping part of the clamping component presses against the upper side of the solid part around the clamping mounting hole on the new molding die, pressing the new molding die onto the molding die mounting plate, completing the installation of the new molding die. This allows for quick and convenient modification of the mold for the production of new products.

[0009] Typically, the aforementioned molding die mounting plate is equipped with multiple molding die clamping mechanisms; each molding die has multiple (e.g., three) clamping mounting holes, corresponding to a certain number of molding die clamping mechanisms. One or more molding dies can be mounted on the molding die mounting plate.

[0010] Typically, the position switching mechanisms of each clamping component are controlled and operate uniformly. In a preferred embodiment, the aforementioned mold with quick-release molding die also includes a control circuit and a position switching command input device. The position switching command input device is electrically connected to the corresponding input terminal of the control circuit, and each clamping component position switching mechanism is electrically connected to the corresponding output terminal of the control circuit. When it is necessary to switch the position of the clamping component by the position switching mechanism, the position switching command input device inputs a command. After processing by the control circuit, a control signal is sent to cause each clamping component position switching mechanism to operate simultaneously, switching the position of its clamping component. To avoid misoperation, the position switching command input device can input commands in two steps. For example, to release the clamping part of the clamping component from the solid part surrounding the clamping mounting hole, first click or press the "Release Molding Die" button, and then click or press the "Confirm" button; to press the clamping part of the clamping component against the upper side of the solid part surrounding the clamping mounting hole, first click or press the "Pressure Molding Die" button, and then click or press the "Confirm" button.

[0011] The aforementioned switching command input device can be a touch screen or a button switch panel.

[0012] Typically, the molded part above the clamping mounting hole has space for the clamping component to move.

[0013] In a preferred embodiment, the molding die clamping mechanism includes two clamping components arranged side-by-side, each with a pressing portion at its upper end. The clamping component position switching mechanism includes a base, a position switching cylinder, and two connecting rods. The base is mounted on the lower surface of the molding die mounting plate, and the position switching cylinder is mounted on the base with its piston rod facing upward. The middle portions of the two clamping components are respectively hinged to the base (the hinge portions of the middle portions of the two clamping components and the base are arranged side-by-side), the lower ends of the two connecting rods are hinged to the piston rods of the position switching cylinder, and the upper ends of the two connecting rods are respectively hinged to the lower ends of the two clamping components. The molding die mounting plate has through holes at positions corresponding to the clamping components (the shape and size of the through holes can be the same as the clamping mounting holes, and the through holes and clamping mounting holes are aligned with each other), and the upper parts of the two clamping components are located in the through holes. When the piston rod of the position switching cylinder extends, it drives two clamping components to rotate around the hinge in the middle via two connecting rods. The lower ends of the two clamping components separate, causing the pressing parts at the upper ends of the two clamping components to move closer together. After the pressing parts of the two clamping components move closer together, they are within the range of the clamping mounting hole. When the piston rod of the position switching cylinder retracts, it drives the two clamping components to rotate in the opposite direction around the hinge in the middle via two connecting rods. This causes the pressing parts of the two clamping components to separate and press against the upper surface of the solid part around the clamping mounting hole. In addition, the clamping component position switching mechanism also includes an electromagnetic reversing valve for controlling the air inlet and outlet direction of the position switching cylinder. The electromagnetic reversing valve is electrically connected to the corresponding output terminal of the control circuit. Each clamping component position switching mechanism can share a single electromagnetic reversing valve, which uniformly controls the air inlet and outlet direction of the position switching cylinder in each clamping component position switching mechanism, causing the piston rod of each position switching cylinder to extend or retract.

[0014] In a more preferred embodiment, the upper end of the clamping component is hook-shaped, and the end of the hook-shaped portion constitutes a pressing part; the upper end of the left clamping component is bent to the left into a hook shape, and the upper end of the right clamping component is bent to the right into a hook shape.

[0015] In another preferred embodiment, the molding die clamping mechanism includes two clamping components arranged side-by-side, each with a pressing portion at its upper end. The clamping component position switching mechanism includes a base, a position switching electric cylinder, and two connecting rods. The base is mounted on the lower surface of the molding die mounting plate, and the position switching electric cylinder is mounted on the base with its push rod facing upwards. The middle portions of the two clamping components are hinged to the base (the hinged portions of the two clamping components and the base are arranged side-by-side), the lower ends of the two connecting rods are hinged to the upper ends of the push rods of the position switching electric cylinder, and the upper ends of the two connecting rods are hinged to the lower ends of the two clamping components. The molding die mounting plate has through holes at positions corresponding to the clamping components (the shape and size of the through holes can be the same as the clamping mounting holes, and the through holes and clamping mounting holes are aligned). The upper parts of the two clamping components are located within the through holes. The position switching electric cylinder, through the linear up-and-down movement of its push rod, drives the two clamping components to switch positions via the two connecting rods. When the push rod of the position switching electric cylinder extends, it drives two clamping components to rotate around the hinge in the middle via two connecting rods. The lower ends of the two clamping components separate, causing the pressing parts at the upper ends of the two clamping components to come together. After the pressing parts of the two clamping components come together, they are within the range of the clamping mounting hole. When the push rod of the position switching electric cylinder retracts, it drives the two clamping components to rotate in the opposite direction around the hinge in the middle via two connecting rods. This causes the pressing parts of the two clamping components to separate and press against the upper surface of the solid part around the clamping mounting hole. Typically, in the above-mentioned clamping component position switching mechanism, the position switching electric cylinder is electrically connected to the corresponding output terminal of the control circuit.

[0016] In a more preferred embodiment, the upper end of the clamping component is hook-shaped, and the end of the hook-shaped portion constitutes a pressing part; the upper end of the left clamping component is bent to the left into a hook shape, and the upper end of the right clamping component is bent to the right into a hook shape.

[0017] In another preferred embodiment, the above-mentioned molding die clamping mechanism includes two clamping components that intersect in an X-shape, and each clamping component has a pressing part at its upper end; the clamping component position switching mechanism includes a base, a position switching cylinder, and two connecting rods; the base is mounted on the lower surface of the molding die mounting plate, the position switching cylinder is mounted on the base with its piston rod facing upward; the middle parts of the two clamping components are hinged to the same part of the base, the lower ends of the two connecting rods are hinged to the piston rod of the position switching cylinder, and the upper ends of the two connecting rods are respectively hinged to the lower ends of the two clamping components; the molding die mounting plate is provided with through holes at positions corresponding to the clamping components (the shape and size of the through holes can be the same as the clamping mounting holes, and the positions of the through holes and the clamping mounting holes are aligned with each other), and the upper parts of the two clamping components are located in the through holes. When the piston rod of the position switching cylinder retracts, it drives two clamping components to rotate around the hinge in the middle via two connecting rods. The lower ends of the two clamping components move closer together, causing the pressing parts at the upper ends of the two clamping components to move closer together, and the pressing parts of the two clamping components are within the range of the clamping mounting hole after they move closer together. When the piston rod of the position switching cylinder extends, it drives the two clamping components to rotate in the opposite direction around the hinge in the middle via two connecting rods. The lower ends of the two clamping components separate from each other, causing the pressing parts of the two clamping components to separate and press against the upper surface of the solid part around the clamping mounting hole. In addition, the clamping component position switching mechanism also includes an electromagnetic reversing valve for controlling the air inlet and outlet direction of the position switching cylinder. The electromagnetic reversing valve is electrically connected to the corresponding output terminal of the control circuit. Each clamping component position switching mechanism can share a single electromagnetic reversing valve, which uniformly controls the air inlet and outlet direction of the position switching cylinder in each clamping component position switching mechanism, causing the piston rod of each position switching cylinder to extend or retract.

[0018] In a more preferred embodiment, the upper end of the clamping member is hook-shaped, and the end of the hook-shaped part constitutes a pressing part; among the two clamping members that are X-shaped and intersecting, the upper end of the upper left clamping member is bent to the left into a hook shape, and the upper end of the upper right clamping member is bent to the right into a hook shape.

[0019] In another preferred embodiment, the above-mentioned molding die clamping mechanism includes a clamping component, which is a strip-shaped pressure bar with its length direction horizontal, and each end of the strip-shaped pressure bar has a pressing part; the clamping component position switching mechanism includes a base and a rotary lifting cylinder (rotary lifting cylinder), the base is installed on the lower surface of the molding die mounting plate, the rotary lifting cylinder is installed on the base with its piston rod facing upward; the middle part of the strip-shaped pressure bar is connected to the piston rod of the rotary lifting cylinder; the clamping mounting hole is a strip-shaped hole (such as a rectangular hole), the length and width of the strip-shaped hole are both greater than the strip-shaped pressure bar, and the width of the strip-shaped hole is less than the length of the strip-shaped pressure bar; the molding die mounting plate is provided with a through hole at the position corresponding to the clamping component (the shape and size of the through hole can be the same as the clamping mounting hole, and the through hole and the clamping mounting hole are aligned with each other), and the piston rod of the rotary lifting cylinder is located in the through hole. The rotary lifting cylinder is a composite pneumatic actuator that combines rotation and linear lifting functions, and can drive the strip-shaped pressure bar to rotate a certain angle (such as 90 degrees) while rising or falling. The rotary lifting cylinder can switch the position of the strip pressure bar in the following manner: In one position, the strip pressure bar and the strip hole intersect each other (e.g., are perpendicular to each other), and the clamping parts at both ends of the strip pressure bar are respectively pressed against the upper side of the solid parts on both sides of the clamping mounting hole; In another position, the rotary lifting cylinder drives the strip pressure bar to rise and rotate at the same time by a certain angle (e.g., 90 degrees). At this time, the clamping parts at both ends of the strip pressure bar leave the solid parts on both sides of the clamping mounting hole and are located directly above the clamping mounting hole and within the range of the clamping mounting hole.

[0020] The aforementioned quick-assembly and disassembly molding mold can be of various types, such as thermoforming molds. The thermoforming mold can be a negative pressure thermoforming mold, a positive pressure thermoforming mold, or a thermoforming mold that combines positive and negative pressure.

[0021] In this invention, the terms "upper" and "lower" are relative. The side of the molding die mounting plate used to mount the molding dies is called the upper surface, and the other side is called the lower surface. In practical applications, when installed on a molding machine, the side of the molding die mounting plate on which the molding dies are mounted can face upwards, downwards, or be tilted.

[0022] This invention enables quick disassembly and installation of the molding mold through the cooperation between the molding mold clamping mechanism and the clamping mounting holes on the molding mold, thus achieving rapid mold replacement. This allows for quick and convenient modification of the mold for the production of other products, saving costs and improving work efficiency. Attached Figure Description

[0030] Example 1, as Figures 1-3 As shown, this quick-assembly and disassembly molding die includes a molding die mounting plate 1 and at least one molding die 2, each molding die 2 being mounted on the upper surface of the molding die mounting plate 1; the molding die mounting plate 1 is provided with at least one molding die clamping mechanism 3, and the bottom of the molding die 2 is provided with clamping mounting holes 21 corresponding to the molding die clamping mechanism 3; the molding die clamping mechanism 3 includes a clamping component position switching mechanism and at least one clamping component 31, the clamping component 31 having a pressing part 32. The clamping component position switching mechanism can switch the position of the clamping component 31, so that the pressing part 32 of the clamping component switches between the following two positions: in one position, the pressing part 32 of the clamping component presses against the upper side of the solid part surrounding the clamping mounting hole 21; in the other position, the pressing part 32 of the clamping component moves away from the solid part surrounding the clamping mounting hole 21 and is within the range of the clamping mounting hole 21.

[0031] The molding die has space above the clamping mounting hole for the clamping component to move. In this embodiment, the molding die 2 includes a molding die body 22 and a base plate 23. The molding die body 22 has a molding die cavity 24. The molding die body 22 is fixedly mounted on the upper surface of the base plate 23. The clamping mounting hole 21 is provided on the base plate 23. There is a space 25 between the molding die body 22 and the upper surface of the base plate 23 for the clamping component 31 to move.

[0032] In this embodiment, the molding mold mounting plate 1 is provided with multiple molding mold clamping mechanisms 3; each molding mold 2 is provided with multiple (e.g., three) clamping mounting holes 21, and corresponding to a corresponding number of molding mold clamping mechanisms 3.

[0033] The aforementioned mold with quick-release molding die also includes a control circuit and a position switching command input device. The position switching command input device is electrically connected to the corresponding input terminal of the control circuit, and each clamping component position switching mechanism is electrically connected to the corresponding output terminal of the control circuit. When it is necessary to change the position of the clamping component by the clamping component position switching mechanism, the position switching command input device inputs a command. After processing by the control circuit, a control signal is sent to cause each clamping component position switching mechanism to operate simultaneously, switching the position of its clamping component. To avoid misoperation, the position switching command input device can input commands in two steps. For example, to release the clamping part of the clamping component from the solid part around the clamping mounting hole, first click or press the "Release Molding Die" button, and then click or press the "Confirm" button; to press the clamping part of the clamping component against the upper side of the solid part around the clamping mounting hole, first click or press the "Clamp Molding Die" button, and then click or press the "Confirm" button. The aforementioned switching command input device can be a touch screen or a button switch panel.

[0034] In this embodiment, the molding die clamping mechanism 3 includes two clamping components 31, which are arranged side by side. Each clamping component 31 has a pressing part 32 at its upper end. The clamping component position switching mechanism includes a base 33, a position switching cylinder 34, and two connecting rods 35. The base 33 is mounted on the lower surface of the molding die mounting plate 1, and the position switching cylinder 34 is mounted on the base 33 with its piston rod facing upwards. The middle portions of the two clamping components 31 are respectively hinged to the base 33 (the two clamping components 31...). The hinged parts 37 of the middle part and the base 33 are arranged side by side. The lower ends of the two connecting rods 35 are hinged to the piston rods 341 of the position switching cylinder 34, and the upper ends of the two connecting rods 35 are respectively hinged to the lower ends of the two clamping components 31. The molding mold mounting plate 1 is provided with through holes 11 at the positions corresponding to the clamping components 31 (the shape and size of the through holes 11 can be the same as the clamping mounting holes 21, and the positions of the through holes 11 and the clamping mounting holes 21 are aligned with each other). The upper parts of the two clamping components 31 are located in the through holes 11. The upper end of the clamping component 31 is hook-shaped, and the end of the hook-shaped part forms the clamping part 32. The upper end of the left clamping component 31 is bent to the left into a hook shape, and the upper end of the right clamping component 31 is bent to the right into a hook shape. The clamping component position switching mechanism also includes an electromagnetic reversing valve for controlling the air inlet and outlet direction of the position switching cylinder 34. The electromagnetic reversing valve is electrically connected to the corresponding output terminal of the control circuit. Each clamping component position switching mechanism can share a single electromagnetic reversing valve. This electromagnetic reversing valve controls the air inlet and outlet direction of the position switching cylinder 34 in each clamping component position switching mechanism, causing the piston rod 341 of each position switching cylinder 34 to extend or retract.

[0035] The aforementioned mold with quick-release molding can be equipped with a variety of molding cavities (different molding cavities have different shapes and / or sizes). Each molding cavity corresponds to a product. Through the cooperation between the molding clamping mechanism 3 and the clamping mounting hole 21 on the molding cavity and the solid parts around the clamping mounting hole 21, the molding cavity 2 can be quickly replaced.

[0036] The mold for quick assembly and disassembly in this embodiment is a thermoforming mold. The molding mold 2 is provided with an exhaust channel 26 (in this embodiment, the exhaust channel 26 is provided on the molding mold body 22). One end of the exhaust channel 26 is connected to the molding mold cavity 24, and the other end of the exhaust channel 26 can be connected to a vacuum device or to the outside.

[0037] The working principle of this quick-assembly molding die is briefly described below:

[0038] During the initial assembly stage, the clamping component position switching mechanism moves the clamping part 32 of the clamping component away from the solid part surrounding the clamping mounting hole 21 (at this time, the piston rod 341 of the position switching cylinder 34 extends, and through two connecting rods 35, drives the two clamping components 31 to rotate around the hinge in the middle, the lower ends of the two clamping components 31 separate, and the clamping parts 32 at the upper ends of the two clamping components 31 move closer to each other). At this time, the clamping mounting hole 21 on the molding die 2 can be aligned and fitted, and the clamping part 32 of the clamping component is within the range of the clamping mounting hole 21; then the clamping component position switching mechanism switches the position of the clamping component 31, so that the clamping part 32 of the clamping component presses against the upper side of the solid part surrounding the clamping mounting hole 21, thereby pressing the molding die 2 onto the molding die mounting plate 1 and fixing the position of the molding die 2 (see reference). Figure 2 At this time, the piston rod 341 of the position switching cylinder 34 retracts, and through the two connecting rods 35, it drives the two clamping components 31 to rotate in opposite directions around the hinge in the middle, so that the pressing parts 32 of the two clamping components separate from each other and press against the upper side of the solid part around the clamping mounting hole 21; after the molding molds 2 are installed, production can begin.

[0039] When producing other products, the clamping component position switching mechanism switches the position of the clamping component 31, causing the clamping part 32 of the clamping component to move away from the solid portion surrounding the clamping mounting hole 21 and into the range of the clamping mounting hole 21 (see reference). Figure 3At this time, the piston rod 341 of the position switching cylinder 34 extends, and drives the two clamping components 31 to rotate around the hinge in the middle through the two connecting rods 35. The lower ends of the two clamping components 31 separate, so that the pressing parts 32 at the upper ends of the two clamping components 31 move closer to each other. After the pressing parts 32 of the two clamping components move closer to each other, they are within the range of the clamping mounting hole 21. At this time, the pressing parts 32 of the clamping components will not hinder the removal and placement of the molding mold 2. The original molding mold can be removed, and the clamping mounting hole 21 on the new molding mold 2 can be aligned and fitted in. Then, the clamping component position switching mechanism switches the position of the clamping component 31 again, so that the pressing parts 32 of the clamping components press against the upper side of the solid part around the clamping mounting hole 21 on the new molding mold 2, pressing the new molding mold 2 onto the molding mold mounting plate 1, completing the installation of the new molding mold, thereby completing the mold modification quickly and conveniently for the production of new products.

[0040] Example 2, Reference Figures 4-5 In this embodiment, the molding die clamping mechanism 3 includes two clamping components 31, which are X-shaped and intersecting each other. Each clamping component 31 has a pressing part 32 at its upper end. The clamping component position switching mechanism includes a base 33, a position switching cylinder 34, and two connecting rods 35. The base 33 is installed on the lower surface of the molding die mounting plate 1, and the position switching cylinder 34 is installed on the base with its piston rod 341 facing upward. The middle parts of the two clamping components 31 are hinged to the same part of the base 33, and the lower ends of the two connecting rods 35 are hinged to the piston rod 341 of the position switching cylinder 34. The upper ends of the two connecting rods 35 are respectively hinged to the lower ends of the two clamping components 31. The molding die mounting plate 1 is provided with through holes 11 at the positions corresponding to the clamping components 31 (the shape and size of the through holes 11 can be the same as the clamping mounting holes 21, and the positions of the through holes 11 and the clamping mounting holes 21 are aligned with each other). The upper parts of the two clamping components 31 are located in the through holes 11. The upper end of the clamping member 31 is hook-shaped, and the end of the hook-shaped part constitutes the pressing part 32; among the two clamping members 31 that are X-shaped, the upper end of the upper left clamping member 31 is bent to the left into a hook shape, and the upper end of the upper right clamping member 31 is bent to the right into a hook shape.

[0041] The remaining structures of this embodiment 2 can be configured with reference to embodiment 1.

[0042] The working principle of this quick-assembly molding die is briefly described below:

[0043] refer to Figure 4 When the piston rod 341 of the position switching cylinder 34 retracts, it drives the two clamping components 31 to rotate around the hinge in the middle via the two connecting rods 35. The lower ends of the two clamping components 31 move closer to each other, causing the pressing parts 32 at the upper ends of the two clamping components to move closer to each other. After the pressing parts 32 of the two clamping components move closer to each other, they are within the range of the clamping mounting hole 21. (Reference) Figure 5 When the piston rod 341 of the position switching cylinder 34 extends, it drives the two clamping components 31 to rotate in opposite directions around the hinge in the middle through the two connecting rods 35. The lower ends of the two clamping components 31 separate from each other, so that the pressing parts 32 of the two clamping components separate from each other and press against the upper side of the solid part around the clamping mounting hole 21.

[0044] Example 3, Reference Figures 6-7 In this embodiment, the molding die clamping mechanism 3 includes a clamping component 31, which is a strip-shaped pressure bar with its length direction horizontal. Each end of the strip-shaped pressure bar has a pressing part 32. The clamping component position switching mechanism includes a base 33 and a rotary lifting cylinder 36. The base 33 is installed on the lower surface of the molding die mounting plate 1, and the rotary lifting cylinder 36 is installed on the base 33 with its piston rod 361 facing upward. The middle part of the strip-shaped pressure bar is connected to the piston rod 361 of the rotary lifting cylinder 36. The clamping mounting hole 21 is a strip-shaped hole (such as a rectangular hole). The length and width of the strip-shaped hole are both greater than the strip-shaped pressure bar, and the width of the strip-shaped hole is less than the length of the strip-shaped pressure bar. The molding die mounting plate 1 is provided with a through hole 11 at the position corresponding to the clamping component 31 (the shape and size of the through hole 11 can be the same as the clamping mounting hole 21, and the positions of the through hole 11 and the clamping mounting hole 21 are aligned with each other). The piston rod 361 of the rotary lifting cylinder 36 is located in the through hole.

[0045] The remaining structures of this embodiment 3 can be configured with reference to embodiment 1.

[0047] refer to Figure 6 The rotary lifting cylinder 36 switches the position of the strip pressure bar (i.e., the clamping component 31) in the following manner: in one position, the strip pressure bar intersects with the strip hole (e.g., they are perpendicular to each other), and the clamping parts 32 at both ends of the strip pressure bar press against the upper side of the solid part on both sides of the clamping mounting hole 21; Reference Figure 7 In another position, the rotary lifting cylinder 36 drives the strip pressure bar to rise and rotate at the same time by a certain angle (such as 90 degrees). At this time, the clamping parts 32 at both ends of the strip pressure bar leave the solid parts on both sides of the clamping mounting hole 21 and are located directly above the clamping mounting hole 21 and within the range of the clamping mounting hole 21.

[0048] In other embodiments, the molding die clamping mechanism includes two clamping components arranged side-by-side, each with a pressing portion at its upper end. The clamping component position switching mechanism includes a base, a position switching electric cylinder, and two connecting rods. The base is mounted on the lower surface of the molding die mounting plate, and the position switching electric cylinder is mounted on the base with its push rod facing upwards. The middle portions of the two clamping components are hinged to the base (the hinged portions of the two clamping components and the base are arranged side-by-side), the lower ends of the two connecting rods are hinged to the upper ends of the push rods of the position switching electric cylinder, and the upper ends of the two connecting rods are hinged to the lower ends of the two clamping components. The position switching electric cylinder, through the linear up-and-down movement of its push rod, drives the two clamping components to switch positions via the two connecting rods. When the push rod of the position switching electric cylinder extends, it drives two clamping components to rotate around the hinge in the middle via two connecting rods. The lower ends of the two clamping components separate, causing the pressing parts at the upper ends of the two clamping components to come together. After the pressing parts of the two clamping components come together, they are within the range of the clamping mounting hole. When the push rod of the position switching electric cylinder retracts, it drives the two clamping components to rotate in the opposite direction around the hinge in the middle via two connecting rods. This causes the pressing parts of the two clamping components to separate and press against the upper surface of the solid part around the clamping mounting hole. In the above-mentioned clamping component position switching mechanism, the position switching electric cylinder is electrically connected to the corresponding output terminal of the control circuit. The upper end of the clamping component is hook-shaped, and the end of the hook-shaped part constitutes the pressing part; the upper end of the left clamping component bends to the left into a hook shape, and the upper end of the right clamping component bends to the right into a hook shape.
