Description

Technical Field

[0001] This utility model relates to a mold with ejection and demolding function, belonging to the field of mold technology. Background Technology

[0002] Molds are various shapes and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to create shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly achieves the processing of the object's shape by changing the physical state of the material being molded. Molds are often referred to as the "mother of industry."

[0003] In common stamping dies, an ejector mechanism is often provided inside the die to facilitate the removal of the object from the die. This allows the object to be separated from the die for easy removal. However, the object generates heat after being extruded and formed in the die. The commonly used ejector mechanism does not have a cooling function and cannot quickly cool down the object formed in the die. This causes the object to deform easily when ejected at high temperatures, reducing the quality of the processed object.

[0004] Therefore, there is an urgent need to improve the mold by providing an ejection and demolding function to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a mold with an ejection and demolding function. By setting a cooling ejection mechanism, the top plate inside the mold body has the function of cooling and reducing the temperature of the object. After cooling and reducing the temperature of the object, deformation of the object can be effectively avoided during ejection, thus avoiding affecting the quality of the object processing.

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0007] A mold with ejection and demolding function includes a support frame, on which a mold body is fixedly mounted. A stamping plate is disposed above the mold body. A hydraulic cylinder connected to the stamping plate is fixedly mounted on the top of the support frame. The mold body is provided with a cooling ejection mechanism, which includes multiple electric telescopic rods fixedly mounted on the surface of the support frame. A top plate fixedly connected to the multiple electric telescopic rods is disposed inside the mold body. A cooling box connected by bolts is disposed at the bottom of the top plate. Conveying pumps are fixedly mounted on both sides of the cooling box. A conveying pipe is fixedly mounted on one end of the conveying pump. A cooling pipe connected to the conveying pipe is fixedly mounted inside the top plate.

[0008] Preferably, a first threaded cylinder is fixedly installed at both ends of the cooling pipe, and a second threaded cylinder is fixedly installed at one end of the conveying pipe, with a threaded ring for threaded connection between the first threaded cylinder and the second threaded cylinder.

[0009] Preferably, multiple push rods are uniformly fixedly installed on the surface of the threaded ring, and the surface of the push rods is provided with multiple anti-slip cones.

[0010] Preferably, a sealing ring is fixedly installed at one end of the first threaded cylinder, and a sealing groove is provided at one end of the second threaded cylinder.

[0011] Preferably, the support frame is provided with a control panel, and the control panel is electrically connected to the hydraulic cylinder, the electric telescopic rod, the cooling box and the delivery pump.

[0012] Preferably, a slide rail is fixedly mounted on the surface of the support frame, and a fixed bracket connected to the control panel is movably mounted on the slide rail.

[0013] Preferably, a support rod is movably mounted on the fixed frame, a spring is installed between the fixed frame and the support rod, a magnetic block is fixedly mounted at one end of the support rod, and a magnetic plate is fixedly mounted on the surface of the support frame.

[0014] This utility model has at least the following beneficial effects:

[0015] By setting up a cooling ejection mechanism, the top plate inside the mold body has the function of cooling the workpiece. After the workpiece is formed by the stamping plate inside the mold body, the coolant in the cooling tank is transported to the cooling pipe by the delivery pump at the bottom of the top plate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-6 As shown in the figure, this embodiment provides a mold embodiment with ejection and demolding function.

[0026] A mold with ejection and demolding function includes a support frame 1, a mold body 2 fixedly mounted on the support frame 1, a stamping plate 3 above the mold body 2, a hydraulic cylinder 4 connected to the stamping plate 3 fixedly mounted on the top of the support frame 1, a cooling ejection mechanism 5 on the mold body 2, the cooling ejection mechanism 5 including multiple electric telescopic rods 6 fixedly mounted on the surface of the support frame 1, a top plate 7 fixedly connected to the multiple electric telescopic rods 6 inside the mold body 2, a cooling box 8 connected by bolts at the bottom of the top plate 7, a delivery pump 9 fixedly mounted on both sides of the cooling box 8, a delivery pipe 10 fixedly mounted on one end of the delivery pump 9, and a cooling pipe 11 connected to the delivery pipe 10 fixedly mounted inside the top plate 7.

[0027] By setting the cooling ejection mechanism 5, the top plate 7 inside the mold body 2 has the function of cooling the object. After the object is squeezed and formed by the stamping plate 3 inside the mold body 2, the coolant in the cooling box 8 is transported to the cooling pipe 11 by the conveying pump 9 at the bottom of the top plate 7. The cooling pipe 11 located inside the top plate 7 can cool the object by the circulation of the coolant. After the object is cooled, multiple electric telescopic rods 6 are activated simultaneously to drive the top plate 7 to rise and eject the object from the mold body 2, effectively avoiding deformation of the object during ejection and avoiding affecting the quality of the object processing.

[0028] In this embodiment, as Figures 1-6 As shown, a first threaded cylinder 12 is fixedly installed at both ends of the cooling pipe 11, and a second threaded cylinder 13 is fixedly installed at one end of the conveying pipe 10. A threaded ring 14 is provided between the first threaded cylinder 12 and the second threaded cylinder 13. Multiple push rods 15 are uniformly fixedly installed on the surface of the threaded ring 14, and multiple anti-slip cones are provided on the surface of the push rods 15. A sealing ring 16 is fixedly installed at one end of the first threaded cylinder 12, and a sealing groove 17 is opened at one end of the second threaded cylinder 13.

[0029] The cooling pipe 11 and the conveying pipe 10 are connected and fixed by the first threaded cylinder 12, the second threaded cylinder 13, and the threaded ring 14, which are used to secure the first threaded cylinder 12 and the second threaded cylinder 13 together. This allows the conveying pipe 10 to be disassembled and separated from the cooling pipe 11. Disassembly is completed by rotating the threaded ring 14 and screwing it onto the first threaded cylinder 12. Furthermore, since the cooling box 8 is fixed to the bottom of the top plate 7 by multiple bolts, after separating the conveying pipe 10 and the cooling pipe 11, the cooling box 8 can be easily removed from the bottom of the top plate 7. To facilitate maintenance and replacement in case of malfunction in the cooling tank 8, the push rod 15 makes it easier to rotate and engage the threaded ring 14 when installing and disassembling the delivery pipe 10 and the cooling pipe 11. At the same time, the anti-slip cone increases the friction on the surface of the push rod 15, preventing slippage during pushing. With the sealing ring 16 and the sealing groove 17, after the first threaded cylinder 12 and the second threaded cylinder 13 are connected, the sealing ring 16 and the sealing groove 17 are tightly engaged, improving the sealing performance between the first threaded cylinder 12 and the second threaded cylinder 13 and preventing coolant leakage.

[0030] In this embodiment, as Figures 1-6As shown, a control panel 18 is provided on the support frame 1. The control panel 18 is electrically connected to the hydraulic cylinder 4, the electric telescopic rod 6, the cooling box 8, and the delivery pump 9. A slide rail 19 is fixedly installed on the surface of the support frame 1. A fixed frame 20 connected to the control panel 18 is movably installed on the slide rail 19. A support rod 21 is movably installed on the fixed frame 20. A spring 22 is installed between the fixed frame 20 and the support rod 21. A magnet 23 is fixedly installed at one end of the support rod 21. A magnetic plate 24 is fixedly installed on the surface of the support frame 1.

[0031] The control panel 18 facilitates centralized operation of the hydraulic cylinder 4, electric telescopic rod 6, cooling tank 8, and delivery pump 9. The control panel 18, via the slide rail 19 and fixed frame 20, allows for position adjustment by sliding along the slide rail 19, enabling operation from different locations. The support rod 21, spring 22, magnet 23, and magnetic plate 24, after the control panel 18 is adjusted, the spring 22's extension and retraction pushes the support rod 21 to move along the fixed frame 20, causing the magnet 23 at one end of the support rod 21 to engage with the magnetic plate 24. The magnetic attraction between the magnet 23 and the magnetic plate 24 limits the position of the fixed frame 20, indirectly fixing the control panel 18.

[0032] In this embodiment, as Figures 1-6 As shown in the figure, the working process of a mold with ejection and demolding function provided in this embodiment is as follows:

[0033] After the object is extruded and formed by the stamping plate 3 in the mold body 2, the coolant in the cooling box 8 is transported to the cooling pipe 11 by the conveying pump 9 at the bottom of the top plate 7. The cooling pipe 11 located inside the top plate 7 can cool and reduce the temperature of the object by the circulation of the coolant. After the object is cooled and reduced, multiple electric telescopic rods 6 are connected to an external power source and the multiple electric telescopic rods 6 are started simultaneously to drive the top plate 7 to rise and push the object out of the mold body 2.

[0034] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
