Description

Technical Field

[0001] This utility model relates to the field of sculpture production technology, specifically a 3D sculpture mold device with a rapid demolding structure. Background Technology

[0002] 3D sculpture mold devices with rapid demolding structures achieve rapid and non-destructive separation of the mold after molding by integrating a pneumatic-mechanical composite drive system and a multi-stage ejection structure. These devices typically consist of a mold body, a rapid demolding structure, and a temperature control system. During use, the upper and lower molds are closed, molten material is injected into the inner cavity, and the temperature control system maintains a suitable temperature to promote solidification. During demolding, the pneumatic system is activated, and high-pressure gas is rapidly injected into the annular air cavity, pushing the ejector plate upwards, causing the entire product to detach from the lower mold cavity. These 3D sculpture mold devices are widely used in art sculpture, cultural creativity, and industrial design.

[0003] For example, Chinese patent CN214562360U, entitled "A Silicone Mold for Sculpting," includes a mold base and a set of opposing vertical mounting plates fixedly installed on the mold base. The mold base is equipped with a mold making mechanism. The mold making mechanism includes a set of opposing mold side plates, a set of opposing fixing rods, a front fixing plate, a fixing nut, a rotating screw, a fixing block, a rear fixing plate, a stepper motor, a reciprocating lead screw, a reciprocating lead nut, a mounting plate, a liquid storage cylinder, a sealing cover, a stirring motor, a stirring shaft, a driving bevel gear, a driven shaft, a driven bevel gear, several spiral stirring blades, a sealing shell, and a set of blowers.

[0004] While the existing technologies can produce the products, in practical use, on the one hand, demolding is not convenient enough. Usually, operators need to use tools to remove the products from the fixed mold, which increases the workload of product removal. On the other hand, the cooling effect of the products is not good enough. Usually, the products are cooled by natural cooling before demolding, which reduces the demolding efficiency. Therefore, they do not meet the current needs. In response, we propose a 3D sculpture product mold device with a rapid demolding structure. Utility Model Content

[0005] The purpose of this invention is to provide a 3D sculpture product mold device with a rapid demolding structure, so as to solve the problems mentioned in the background art of inconvenient product demolding and poor product cooling effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a 3D sculpture product mold device with a rapid demolding structure, including a processing table, with frames fixedly installed at the four corners of the lower end of the processing table, a base installed at the center of the upper end of the processing table, a fixed mold fixedly installed at the upper end of the base, four fixed cavities installed at the lower end of the fixed mold, the fixed cavities communicating with the forming cavity of the fixed mold and being equidistantly distributed, a third hydraulic telescopic device fixedly installed inside the fixed cavity, the telescopic end of the third hydraulic telescopic device extending into the forming cavity of the fixed mold, an ejector plate fixedly installed at the upper end of the telescopic end of the third hydraulic telescopic device, the ejector plate contacting the lower end and side wall of the forming cavity.

[0007] Preferably, a cooling pipe is provided inside the side wall of the fixed mold. The cooling pipes are arranged in a ring, and both ends of the cooling pipes extend to the outside of the fixed mold. An inlet pipe is sleeved on the outside of one end of the cooling pipe, and an outlet pipe is sleeved on the outside of the other end of the cooling pipe. The inlet pipe and the outlet pipe are both connected to the cooling pipe by threads, and the other ends of the inlet pipe and the outlet pipe extend to the bottom of the processing table.

[0008] Preferably, a base plate is fixedly installed between the frames, and a water pump assembly is installed on one side of the upper end of the base plate. The water pump assembly is connected to the other end of the liquid inlet pipe, and a water tank is installed on the other side of the upper end of the base plate. The water tank is connected to the other end of the liquid outlet pipe, and the water tank is connected to the water pump assembly through a pipe.

[0009] Preferably, a fixed frame is fixedly installed on the upper end of the processing table outside the fixed mold. Both sides of the base are provided with snap-fit ​​grooves, the upper end of the snap-fit ​​grooves is an open structure. A first hydraulic telescopic device is fixedly installed on the lower side of both sides of the fixed frame. The telescopic end of the first hydraulic telescopic device passes through the fixed frame. An extrusion plate is fixedly installed on one side of the telescopic end of the first hydraulic telescopic device, and the extrusion plate extends into the interior of the snap-fit ​​groove.

[0010] Preferably, a second hydraulic telescopic device is fixedly installed on both sides of the upper end of the fixed frame, the telescopic end of the second hydraulic telescopic device extends to the lower part of the fixed frame, and a moving mold is fixedly installed at the lower end of the telescopic end of the second hydraulic telescopic device.

[0011] Preferably, a positioning groove is provided at the upper part of the interior of the fixed mold, the upper end of the positioning groove is an open structure, and an insert plate is fixedly provided at the lower end of the moving mold, the insert plate corresponding to the position of the positioning groove.

[0012] Preferably, a first control panel is fixedly installed at the front end of the processing table, and the first control panel is electrically connected to a first hydraulic telescopic device, a second hydraulic telescopic device, and a water pump assembly. A second control panel is fixedly installed at the front end of the base, and the second control panel is electrically connected to a third hydraulic telescopic device.

[0013] Compared with the prior art, the beneficial effects of this utility model are: (1) This utility model can eject the cooled and molded product from the fixed mold through the third hydraulic telescopic device and the ejector plate. When demolding, the product has been cooled to a suitable temperature. At this time, the operator opens the third hydraulic telescopic device through the second control panel, so that the telescopic end of the third hydraulic telescopic device extends. The extension of the telescopic end of the third hydraulic telescopic device pushes the ejector plate to move slowly and uniformly upward. Under the action of the ejector plate, the product in the fixed mold is gradually ejected from the fixed mold. At this time, the operator takes the product out of the fixed mold and continues to keep the ejector plate in the rising state so that the ejector plate scrapes off the debris attached to the side wall of the fixed mold, thereby improving the convenience of product demolding.

[0014] (2) This utility model can accelerate the heat dissipation of the product by means of cooling pipe and water pump assembly. When demolding, the heat on the product is transferred to the fixed mold. The operator first turns on the water pump assembly through the first control panel so that the water pump assembly draws coolant from the water tank through the pipe. At this time, the coolant is transported to the cooling pipe through the liquid inlet pipe on the water pump assembly. The heat on the fixed mold is transferred to the coolant through the cooling pipe. Finally, the coolant that has absorbed the heat flows back to the water tank through the liquid outlet pipe. At this time, the operator detects the temperature on the product through an infrared temperature detector until the product drops to a suitable demolding temperature. At the same time, the operator adjusts the water pump during cooling so that the product cools down step by step, thereby accelerating the efficiency of heat dissipation of the product.

[0015] (3) This utility model can quickly fix the fixed mold through the extrusion plate and the snap-fit ​​groove. When it is necessary to fix the fixed mold, the operator first places the fixed mold together with the base on the processing table. At this time, the operator opens the first hydraulic telescopic device through the first control panel, so that the telescopic end of the first hydraulic telescopic device extends. The extension of the telescopic end of the first hydraulic telescopic device drives the extrusion plate to move towards each other until the extrusion plate is moved to the appropriate position. At this time, the extrusion plate enters the snap-fit ​​groove and contacts the base and causes extrusion. If the fixed mold position is offset, the extrusion plate will contact the side of the base. At this time, the operator adjusts the position of the fixed mold, thereby improving the flexibility of the fixed mold installation. Attached Figure Description

The forming cavity depth of the moving mold 10 is shallower than the forming cavity depth of the fixed mold 9.

[0020] Please see Figure 1 , Figure 2 and Figure 4 A base 8 is provided at the center of the upper end of the processing table 1. A fixed mold 9 is fixedly provided at the upper end of the base 8. Four fixed cavities 21 are provided at the lower end of the fixed mold 9. The fixed cavities 21 are connected to the molding cavity of the fixed mold 9 and are evenly distributed. A third hydraulic telescopic device 22 is fixedly provided inside the fixed cavity 21. The telescopic end of the third hydraulic telescopic device 22 extends into the molding cavity of the fixed mold 9. An ejector plate 19 is fixedly provided at the upper end of the telescopic end of the third hydraulic telescopic device 22. The ejector plate 19 contacts the lower end and side wall of the molding cavity, so that the cooled and molded product can be ejected from the fixed mold 9 through the ejector plate 19.

[0021] Please see Figure 1 , Figure 2 and Figure 3 Cooling pipes 23 are arranged inside the side wall of the fixed mold 9. The cooling pipes 23 are arranged in a ring and both ends of the cooling pipes 23 extend to the outside of the fixed mold 9. An inlet pipe 6 is sleeved on the outside of one end of the cooling pipe 23 and an outlet pipe 17 is sleeved on the outside of the other end of the cooling pipe 23. The inlet pipe 6 and the outlet pipe 17 are both connected to the cooling pipe 23 by threads, and the other ends of the inlet pipe 6 and the outlet pipe 17 extend to the bottom of the processing table 1. A base plate 3 is fixedly installed between the frames 2. A water pump assembly 5 is installed on one side of the upper end of the base plate 3. The water pump assembly 5 is connected to the other end of the inlet pipe 6. A water tank 4 is installed on the other side of the upper end of the base plate 3.

[0022] Please see Figure 1 and Figure 2 A fixed frame 11 is fixedly installed on the upper end of the processing table 1 outside the fixed mold 9. Both sides of the base 8 are provided with snap-fit ​​grooves 14. The upper end of the snap-fit ​​grooves 14 is open.

The pressing plate 15 extends into the interior of the snap-fit ​​grooves 14, so as to facilitate the fixing of the base 8 by the pressing plate 15.

[0023] Working Principle: In operation, the operator first places the fixed mold 9 along with the base 8 onto the processing table 1. Then, the operator activates the first hydraulic telescopic device 12 via the first control panel 7, extending its telescopic end. This extension causes the extrusion plate 15 to move towards the other side until it reaches the appropriate position. The extrusion plate 15 then enters the locking groove 14 and contacts the base 8, causing compression. If the fixed mold 9 shifts position, the extrusion plate 15 will contact the side of the base 8. The operator then adjusts the position of the fixed mold 9. During demolding, heat from the product is transferred to the fixed mold 9. The operator then activates the water pump assembly 5 via the first control panel 7, drawing coolant from the water tank 4 through pipes. The coolant is then pumped through the water pump assembly 5... The inlet pipe 6 delivers coolant to the cooling pipe 23. Heat from the fixed mold 9 is transferred to the coolant through the cooling pipe 23. Finally, the coolant that has absorbed heat flows back to the water tank 4 through the outlet pipe 17. At this time, the operator uses an infrared temperature detector to detect the temperature of the product until the product drops to a suitable demolding temperature. Then, the operator activates the third hydraulic telescopic device 22 through the second control panel 16, causing the telescopic end of the third hydraulic telescopic device 22 to extend. The extension of the telescopic end of the third hydraulic telescopic device 22 pushes the ejector plate 19 to move upward slowly and uniformly. Under the action of the ejector plate 19, the product in the fixed mold 9 is gradually ejected from the fixed mold 9. At this time, the operator removes the product from the fixed mold 9 and continues to keep the ejector plate 19 in the rising state so that the ejector plate 19 scrapes off the debris attached to the side wall of the fixed mold 9.
