Description

Technical Field

[0001] This utility model relates to an automatic mold opening device. Background Technology

[0002] A shoe sole demolding machine is a device that removes the molded shoe sole from the mold. Its working principles encompass various methods, including mechanical, hydraulic, pneumatic, and thermal expansion / contraction demolding. Mechanical demolding uses linkages and other structures to apply force to the mold to open it; hydraulic demolding uses a hydraulic system to drive a hydraulic cylinder piston; pneumatic demolding uses compressed air to push a cylinder piston; thermal expansion / contraction demolding first heats the shoe sole material to soften it, then cools it, relying on the difference in their coefficients of thermal expansion and contraction to separate the shoe sole from the mold. Its structure consists of a mechanism for opening and closing the mold, a demolding actuator that directly acts on the shoe sole, a transmission system that provides power, a control system that controls the operating process and parameters, and a heating and cooling system to meet the requirements of thermal expansion and contraction. It is widely used in the manufacturing of various types of shoes, including athletic shoes, leather shoes, and plastic shoes, and can demold soles made of various materials such as EVA, MD, rubber, PVC, and PU. To improve production efficiency, quick-release molds have been developed. Figure 1 As shown, the mold includes an upper mold 12 and a lower mold 11. The upper mold 12 has a lifting arm 121 on its side wall for lifting the upper mold. An abutment plate 13 is slidably disposed in the upper mold 12. The abutment plate 13 is provided with a demolding guide post for abutting the material to be demolded when the upper mold and the abutment plate 13 slide relative to each other. Abutment flanges are formed on both sides of the abutment plate 13 for displacing the abutment plate relative to the upper mold after receiving the abutment. The abutment flanges are exposed outside the mold as a whole. The upper mold 12 is also provided with a locking buckle 122, and the lower mold 11 is provided with a buckle 111. The locking buckle 122 and the buckle 111 engage to lock the separation of the upper mold 12 and the lower mold 11. The locking buckle 122 is located below the lifting arm 121. The locking buckle 122 is also provided with an abutment arm 123 for swinging the locking buckle 122 when it is abutted. Existing equipment cannot be well used with this mold, which reduces production and processing efficiency, and is also not conducive to maintenance, thus reducing the effectiveness of the equipment. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an automatic mold opening device with a simple structure, reasonable layout, high mold opening efficiency, and good reliability and effectiveness.

[0004] To achieve the above objectives, this utility model provides an automatic mold opening device, including a frame. The frame is provided with a receiving station for receiving the mold. The frame is provided with a lifting frame and a drive motor for driving the lifting frame to rise and fall on both sides of the receiving station. The lifting frame is provided with a mating groove for cooperating with the lifting arm of the upper mold side wall. The frame is provided with an operating table in the front and rear directions of the receiving station. The operating table extends towards the receiving station with a boss for abutting the abutting plate and abutting flange to cause relative displacement between the abutting plate and the upper mold.

[0005] The beneficial effects of this design are as follows: When the mold reaches the receiving station, the lifting frame rises, first contacting the abutment arm on the mold lock, causing the lock to swing and disengage. As the lifting frame rises further, the mating groove engages with the lifting arm, thereby driving the upper mold to move. During the movement of the upper mold, the abutment flange of the abutment plate contacts the boss, causing relative displacement between the abutment plate and the upper mold, thus extruding the processed material. At this point, there is a certain height difference between the upper and lower molds, making it convenient for the operator to remove the molded material. This structure is simple, easy to operate, and has excellent performance. Its concise design not only facilitates daily operation and lowers the technical threshold for operators, reducing the probability of errors caused by complex operations, but also significantly improves production efficiency. Furthermore, the simple structure means fewer parts, reducing the frequency of equipment failures and making subsequent maintenance and repair work more convenient, effectively reducing the company's operating costs. It has good performance and broad application prospects, bringing an efficient and stable mold-making solution to related production industries.

[0006] As a further feature of this invention, the operating platform is also provided with a stop for limiting the displacement of the upper mold, and a window is provided between the stop and the boss on the operating platform.

[0007] The advantages of this design are as follows: When the lifting frame moves the upper mold, the side guard effectively prevents excessive displacement of the upper mold, ensuring the stability of the equipment operation and the precision of the mold opening action. Simultaneously, the window on the operating platform between the side guard and the boss provides a convenient passage for removing the molded material. Operators can directly and quickly remove the material through the window, greatly improving the efficiency of material removal and operational convenience.

[0008] As a further feature of this utility model, a slide block is slidably provided on the operating table, and a slide groove and a locking screw hole are provided between the slide block and the operating table. A locking screw is fitted in the locking screw hole, and the head of the locking screw abuts against the outer wall of the slide groove. The baffle and the window are both provided on the slide block.

[0009] The advantages of this design are as follows: It allows for a wide variety of product and mold specifications. By loosening the locking screws, the slide can slide freely within the groove. Operators can flexibly adjust the slide's position according to the size, shape, and other specifications of different products and molds. After the slide is adjusted to the appropriate position, tightening the locking screws will cause the head to firmly abut against the outer wall of the groove, achieving a secure lock. At this point, the positions of the flange and window on the slide are also determined. This not only precisely meets the limiting requirements for upper mold displacement during mold opening for different specifications, ensuring stable and accurate mold opening operations, but also ensures that the window is always in the optimal position for easy material removal, significantly improving material removal efficiency and comprehensively adapting to diverse production needs.

[0010] As a further feature of this invention, the lifting frame is slidably engaged with the frame via guide columns, and a rack is also provided on the lifting frame along the height direction. The drive motor is driven by a transmission shaft, and a transmission gear is provided on the transmission shaft corresponding to the rack position, and the transmission gear meshes with the rack.

[0011] The advantages of this design are as follows: It makes the lifting frame's raising and lowering movement smoother and more stable, effectively preventing deviation and jamming during operation. The rack and pinion mounted along the height direction on the lifting frame precisely meshes with the transmission gear on the drive motor's drive shaft, forming a simple and efficient transmission system. Its simple structure reduces the potential for malfunctions caused by complex transmission components and facilitates installation and maintenance. Simultaneously, the tight meshing of the transmission gear and rack ensures extremely high transmission synchronization, allowing the lifting frame to rise or fall precisely according to the preset speed and stroke, accurately completing the mold lifting operation and greatly improving the stability and reliability of the mold opening process.

The beneficial effects of this design are as follows: When the mold reaches the receiving station, the lifting frame 3 rises, first contacting the contact arm on the mold lock, causing the lock to swing and disengage. As the lifting frame 3 rises further, the mating groove engages with the lifting arm, thereby driving the upper mold to move. During the movement of the upper mold, the contact flange of the contact plate contacts the boss 41, causing relative displacement between the contact plate and the upper mold, thus extruding the processed material. At this time, there is a certain height difference between the upper and lower molds, making it convenient for the operator to remove the molded material. This structure is simple, easy to operate, and has good performance. Its simple design not only facilitates daily operation and lowers the technical threshold for operators, reducing the probability of errors caused by complex operation, but also significantly improves production efficiency. Furthermore, the simple structure means fewer parts, reducing the frequency of equipment failures, and making subsequent maintenance and repair work more convenient, effectively reducing the operating costs of enterprises. It has good performance and broad application prospects, bringing efficient and stable mold opening solutions to related production industries.

[0016] As a further feature of this invention, the operating platform 4 is also equipped with a retaining edge 51 for limiting the displacement of the upper mold, and a window 52 is provided between the retaining edge 51 and the boss 41. The beneficial effects of this design are: when the lifting frame 3 moves the upper mold, the retaining edge 51 can effectively prevent excessive displacement of the upper mold, ensuring the stability of the equipment operation and the accuracy of the mold opening action. Simultaneously, the window 52 provided between the retaining edge 51 and the boss 41 on the operating platform 4 creates a convenient channel for removing the molded material. Operators can directly and quickly remove the material through the window 52, ​​greatly improving the efficiency of material removal and operational convenience.

Both the retaining edge 51 and the window 52 are mounted on the slide block 5. The advantages of this design are: it allows for a wide variety of product and mold specifications. By loosening the locking screw, the slide block 5 can slide freely within the slide groove 53. Operators can flexibly adjust the position of the slide block 5 according to the size, shape, and other specifications of different products and molds. After the slide block 5 is adjusted to the appropriate position, tightening the locking screw will cause its head to firmly abut against the outer wall of the slide groove 53, achieving a secure lock. At this time, the positions of the baffle 51 and window 52 set on the slide block 5 are also determined. This not only accurately meets the limiting requirements of the upper mold displacement when opening molds of different specifications, ensuring the stability and accuracy of the mold opening action, but also ensures that the window 52 is always in the best position for easy material removal, greatly improving the material removal efficiency and adapting to diverse production needs in all aspects.

[0018] As a further feature of this invention, the lifting frame 3 slides with the frame 2 via guide posts 31. A rack 32 is also provided on the lifting frame 3 along its height direction. The drive motor is driven by a transmission shaft 6, and a transmission gear 61 is provided on the transmission shaft 6 corresponding to the rack 32. The transmission gear 61 meshes with the rack 32.

The rack 32 on the lifting frame 3, positioned along its height direction, precisely meshes with the transmission gear 61 on the drive motor's transmission shaft 6, forming a simple and efficient transmission system. Its simple structure reduces the potential for malfunctions caused by complex transmission components and facilitates installation and maintenance. Simultaneously, the tight meshing of the transmission gear 61 and the rack 32 ensures extremely high transmission synchronization, allowing the lifting frame 3 to rise or fall precisely according to a preset speed and stroke, accurately completing the mold lifting operation and greatly improving the stability and reliability of the mold opening process.
