Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a quick change mold for electric cylinder parts. Background Technology

[0002] An electric cylinder, also known as an electric cylinder, is an automated device that integrates a motor, driver, and transmission mechanism, and is widely used in industrial automation. Its working principle involves an electric motor driving a transmission device, causing the cylinder body to move linearly. Quick-change molds for electric cylinder parts are commonly used in automated production lines to enable rapid mold changes, thereby improving production efficiency and reducing downtime.

[0003] Existing technologies, such as the utility model patent with publication number CN219171480U, disclose a mold for quick changeover, including a shared mold frame and an integral mold core. The shared mold frame has a mold core slot on its front for embedding the integral mold core. The integral mold core includes a mold core body and a changeover core, ejector plate, and ejector pins fixedly assembled on the mold core. The quick-change mold also includes a locking structure for locking the shared mold frame and the integral mold core body. The advantages of this utility model are: this technical solution eliminates the need to disassemble the mold frame and mold core during changeover, greatly saving time on mold disassembly and assembly; since the mold core is designed as an integral piece, there is no need to separate the mold core from the mold core during changeover, effectively avoiding the risk of damage or incorrect installation of the mold core during changeover. It solves the problems of long changeover cycles, large changeover workload, and high manpower requirements. In the process of using molds to produce electric cylinder parts, it was found that the mold base needs to be changed to adapt to different types of electric cylinder parts. However, most existing molds are complicated and time-consuming to change the mold base, which leads to reduced work efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, when processing and producing electric cylinder parts, it is necessary to change the mold base to adapt to different types of electric cylinder parts. However, most existing molds are complicated to operate when changing the mold base, which is time-consuming and labor-intensive, resulting in reduced work efficiency.

[0005] To solve the above technical problems, this utility model provides a quick-change mold for electric cylinder parts, including: a base, a top plate, an upper mold base, a lower mold base, and two quick-change devices. Guide pillars are provided at the four corners of the base and top plate near each other. A cylinder is fixedly connected to the surface of the top plate, and a moving plate is fixedly connected to the output end of the cylinder. The inner wall of the moving plate is slidably connected to the guide pillars. The upper mold base is fixedly connected to the moving plate via one of the quick-change devices, and the lower mold base is fixedly connected to the base via the other quick-change device. Each quick-change device includes a connecting seat. The lower surface of the connecting seat is fixedly connected to the base, and the upper surface of the connecting seat is inserted into the lower mold base. A rotating rod is rotatably connected to the inner wall of the connecting seat. A first bevel gear is fixedly connected to one end of the rotating rod. The teeth of the first bevel gear mesh with a second bevel gear, and the inner wall of the second bevel gear is fixed... An adjusting rod is connected, the lower end of which is rotatably connected to a connecting seat. An extrusion block is threaded onto the arc surface of the adjusting rod. The extrusion block has a trapezoidal cross-section. A limit rod slides through one inner wall of the extrusion block, and the lower end of the limit rod is fixedly connected to the connecting seat. Telescopic rods are fixedly connected to both sides of the inner wall of the connecting seat. An adjusting block is fixedly connected to one end of each telescopic rod. A first spring is fitted onto the arc surface of the telescopic rod, and both ends of the first spring are fixedly connected to the extrusion block and the connecting seat, respectively. The adjusting block has a wedge-shaped cross-section. The sides of the two adjusting blocks that are close to each other abut against the same extrusion block. A connecting block is fixedly connected to the surface of the extrusion block. An insertion rod is fixedly connected to one side of the connecting block. The arc surface of the insertion rod is slidably connected to the connecting seat. A slot is provided on the inner wall of the lower mold base corresponding to the position of the insertion rod, and the inner wall of the slot is inserted into the insertion rod.

[0006] The aforementioned components achieve the following effects: When installing the lower mold base, position it on the connecting seat, align the slot with the insert rod, and rotate the rotating rod to drive the first bevel gear, which in turn drives the second bevel gear to rotate, causing the adjusting rod to rotate. The pressing block moves upward along the limiting rod, pressing the adjusting block and thus pushing the insert rod into the slot of the lower mold base, achieving quick installation of the lower mold base. When disassembly is required, rotate the rotating rod in the opposite direction. Under the action of the first bevel gear, the second bevel gear, and the adjusting rod, the pressing block moves downward along the limiting rod, and the adjusting block moves towards the center under the action of the first spring, thereby moving the insert rod away from the slot of the lower mold base, achieving quick disassembly of the lower mold base. The installation and disassembly of the upper mold base follow the same principle.

[0007] Preferably, a guide block is fixedly connected to one end of the insertion rod, and the guide block has a conical structure.

[0008] The effect achieved by the above components is that the tapered structure of the guide block makes it easier for the insert rod to be inserted into the slot, and prevents friction from affecting the tightness between the insert rod and the slot.

[0009] Preferably, a handle is fixedly connected to one end of the rotating rod, and the handle has a circular cross-section.

[0010] The effects achieved by the above components are: the round handle provides a comfortable manual operating point, making it easier and more convenient to turn the lever, enhancing the operating experience, reducing reliance on tools, and improving changeover efficiency.

[0011] Preferably, guide posts are fixedly connected to both sides of the surface of the connecting seat, and guide grooves are opened on the surface of the lower mold base corresponding to the positions of the guide posts, with the inner wall of the guide grooves being inserted into the guide posts.

[0012] The effects achieved by the above components are: the cooperation between the guide post and the guide groove ensures that the lower mold base is correctly positioned during installation, prevents horizontal misalignment, improves the stability of mold connection and centering accuracy, and reduces installation errors.

[0013] Preferably, an auxiliary device is provided on the base surface corresponding to the position of the lower mold base. The auxiliary device includes a slide rail, the lower surface of which is fixedly connected to the base. A slider is slidably connected to the surface of the slide rail, and a movable frame is fixedly connected to the upper surface of the slider. The movable frame has an "L" shaped cross-section. A fixed rod slides through the inner wall of the short arm end of the movable frame. Fixed blocks are fixedly connected to both ends of the fixed rod. One side of the two fixed blocks is fixedly connected to the same base. A scraper is fixedly connected to one side of the long arm end of the movable frame.

[0014] The effect achieved by the above components is as follows: the auxiliary device moves the scraper along the fixed rod by means of the slide rail and slider, which can clean the residue or release agent on the surface of the lower mold base, keep the mold clean, ensure the molding quality of the parts, and reduce manual cleaning time.

[0015] Preferably, the scraper has a pointed conical cross-section and is made of stainless steel.

[0016] The effects achieved by the above components are as follows: the pointed conical scraper improves scraping efficiency and cleaning effect, and can effectively remove stubborn residues; the stainless steel material is corrosion-resistant, durable, adaptable to humid or chemical environments, and extends service life.

[0017] Preferably, a second spring is fitted onto the arc surface of the fixing rod, and the two ends of the second spring are respectively fixedly connected to one of the fixing blocks and the movable frame.

[0018] The effects achieved by the above components are as follows: the second spring provides a restoring force, so that the moving frame and scraper automatically return to their initial positions after cleaning, which facilitates continuous operation, reduces manual adjustment, and improves automation and operating efficiency.

[0019] Compared with related technologies, the quick change mold for electric cylinder parts provided by this utility model has the following beneficial effects: This utility model provides a quick-change mold for electric cylinder parts. When using the mold to process and produce electric cylinder parts, the control system is first activated, the cylinder operates, and its output end pushes a moving plate. The moving plate slides smoothly downwards along the four corner guide posts, causing the upper mold base to move downwards as well. The upper and lower mold bases close, stamping, bending, or forming the raw material of the electric cylinder part placed within. After stamping is complete, the cylinder retracts, pulling the moving plate and the upper mold base upwards along the guide posts to open the mold. The formed electric cylinder part is then removed from the lower mold base, completing the processing. When the lower mold base needs to be installed quickly, align the lower mold base with the connecting seat on the base, and align the guide groove on the lower mold base with the guide post on the connecting seat. Then, slowly lower it. When the guide post is fully inserted into the guide groove and the bottom of the lower mold base is in contact with the surface of the connecting seat, align the slot with the insert rod. Then, turn the round handle to rotate the rotating rod. The rotating rod drives the first bevel gear at its end to rotate. The first bevel gear drives the second bevel gear that meshes with it, thereby driving the adjusting rod to rotate. This causes the extrusion block that is threaded to it to move upward along the limit rod. During the upward movement of the extrusion block, the inclined surfaces on both sides will press against the inclined surfaces of the two adjusting blocks, pushing the two adjusting blocks to overcome the elastic force of the first spring and move outward. The adjusting blocks drive the connecting block and the insert rod to move outward, so that the insert rod is steadily inserted into the slot of the lower mold base under the action of the guide block, thus completing the installation of the lower mold base. When the lower mold base needs to be disassembled, turn the handle in the opposite direction to rotate the rotating rod, which in turn rotates the first bevel gear, the second bevel gear, and the adjusting rod. This causes the extrusion block to move downwards along the limiting rod. At this time, the first spring on the telescopic rod returns to its original deformation, pushing the two adjusting blocks to reset inwards. The adjusting blocks then drive the connecting block and the insert rod to move inwards, allowing the insert rod to completely disengage from the slot of the lower mold base. The lower mold base can then be removed upwards. The disassembly and installation process for the upper mold base is the same as described above. By operating the quick-change device, the mold base can be installed and disassembled.

[0020] When it's necessary to clean residue from the lower mold base, manually push the movable frame. This moves the frame along the slide rail, carrying the scraper. The scraper, with its pointed, conical shape for better cleaning, is made of durable stainless steel. The scraper's edge moves closely against the molding surface of the lower mold base, removing residue. After cleaning, release the hand. The restoring force of the second spring on the fixed rod pushes the movable frame back to its initial position, facilitating the next cleaning cycle and preventing the scraper from remaining in the work area and obstructing other operations. By operating this auxiliary device, the goal of cleaning residue from the lower mold base surface is achieved. Attached Figure Description

[0025] Please see Figures 1 to 6 The present invention provides a quick-change mold for electric cylinder parts, comprising: a base 1, a top plate 4, an upper mold base 6, a lower mold base 7, and two quick-change devices 8.

In the embodiments of this utility model, please refer to Figures 2 to 5The quick-change device 8 includes a connecting seat 801. The lower surface of the connecting seat 801 is fixedly connected to the base 1, and the upper surface of the connecting seat 801 is inserted into the lower mold base 7. A rotating rod 804 is rotatably connected to the inner wall of the connecting seat 801. A first bevel gear 805 is fixedly connected to one end of the rotating rod 804. A second bevel gear 806 meshes with the tooth surface of the first bevel gear 805. An adjusting rod 807 is fixedly connected to the inner wall of the second bevel gear 806. The lower end of the adjusting rod 807 is rotatably connected to the connecting seat 801. An extrusion block 809 is threadedly connected to the arc surface of the adjusting rod 807. The cross-section of the extrusion block 809 is trapezoidal. A limit rod 808 slides through one side of the inner wall of the extrusion block 809. The lower end of the limit rod 808 is fixedly connected to the connecting seat 801. Next, telescopic rods 810 are fixedly connected to both sides of the inner wall of the connecting seat 801. One end of the telescopic rod 810 is fixedly connected to an adjusting block 812. The arc surface of the telescopic rod 810 is fitted with a first spring 811. The two ends of the first spring 811 are fixedly connected to the extrusion block 809 and the connecting seat 801, respectively. The cross section of the adjusting block 812 is wedge-shaped. The side of the two adjusting blocks 812 that are close to each other abuts against the same extrusion block 809. A connecting block 813 is fixedly connected to the surface of the extrusion block 809. An insert rod 814 is fixedly connected to one side of the connecting block 813. The arc surface of the insert rod 814 is slidably connected to the connecting seat 801. A slot 815 is opened on the inner wall of the lower mold base 7 corresponding to the position of the insert rod 814. The inner wall of the slot 815 is inserted into the insert rod 814. When installing the lower mold base 7, position it on the connecting seat 801, aligning the slot 815 with the insert rod 814. Rotating the rotating rod 804 drives the first bevel gear 805, which in turn drives the second bevel gear 806, causing the adjusting rod 807 to rotate. The pressing block 809 moves upward along the limiting rod 808, pressing the adjusting block 812, thereby pushing the insert rod 814 into the slot 815 of the lower mold base 7, achieving quick installation of the lower mold base 7. When disassembly is required, rotate the rotating rod 804 in the opposite direction. Under the action of the first bevel gear 805, the second bevel gear 806, and the adjusting rod 807, the pressing block 809 moves downward along the limiting rod 808, and the adjusting block 812 moves towards the center under the action of the first spring 811, thereby moving the insert rod 814 away from the slot 815 of the lower mold base 7, achieving quick disassembly of the lower mold base 7. The upper mold base 6 is installed and disassembled in the same way. One end of the insertion rod 814 is fixedly connected to a guide block 816, which has a conical structure. The conical structure of the guide block 816 facilitates the insertion of the insertion rod 814 into the slot 815, preventing friction from affecting the tightness between the insertion rod 814 and the slot 815. One end of the rotating rod 804 is fixedly connected to a handle 817, which has a circular cross-section. The circular handle 817 provides a comfortable manual operating point, making it easier and less strenuous to rotate the rotating rod 804, enhancing the operating experience, reducing reliance on tools, and improving changeover efficiency.Guide posts 802 are fixedly connected to both sides of the surface of the connecting seat 801. A guide groove 803 is formed on the surface of the lower mold base 7 corresponding to the position of the guide post 802. The inner wall of the guide groove 803 is inserted into the guide post 802. The cooperation between the guide post 802 and the guide groove 803 ensures the correct positioning of the lower mold base 7 during installation, prevents horizontal misalignment, improves the stability and alignment accuracy of the mold connection, and reduces installation errors. In the embodiments of this utility model, please refer to Figure 1 and Figure 6 The auxiliary device 9 includes a slide rail 91, the lower surface of which is fixedly connected to the base 1. A slider 92 is slidably connected to the surface of the slide rail 91, and a movable frame 93 is fixedly connected to the upper surface of the slider 92. The movable frame 93 has an "L"-shaped cross-section, and a fixed rod 96 slides through the inner wall of the short arm end of the movable frame 93. Fixed blocks 95 are fixedly connected to both ends of the fixed rod 96, and one side of each fixed block 95 is fixedly connected to the same base 1. A scraper 94 is fixedly connected to one side of the long arm end of the movable frame 93. The auxiliary device 9, through the slide rail 91 and slider 92, causes the movable frame 93 to move the scraper 94 along the fixed rod 96, which can clean residues or release agents from the surface of the lower mold base 7, keeping the mold clean, ensuring the quality of part molding, and reducing manual cleaning time. The scraper 94 has a pointed conical cross-section and is made of stainless steel. The pointed conical scraper 94 improves scraping efficiency and cleaning effect, effectively removing stubborn residues; the stainless steel material is corrosion-resistant, durable, adaptable to humid or chemical environments, and extends service life. A second spring 97 is fitted onto the arc surface of the fixed rod 96. The two ends of the second spring 97 are fixedly connected to one of the fixed blocks 95 and the movable frame 93, respectively. The second spring 97 provides a restoring force, so that the movable frame 93 and the scraper 94 automatically return to their initial positions after cleaning, which facilitates continuous operation, reduces manual adjustment, and improves the degree of automation and operating efficiency. The working principle of the quick-change mold for electric cylinder parts provided by this utility model is as follows: When processing electric cylinder parts using the mold, the control system is first started, and the cylinder 5 works. Its output end pushes the moving plate 3. The moving plate 3 slides smoothly downward along the guide posts 2 at the four corners, driving the upper mold base 6 downward together. The upper mold base 6 and the lower mold base 7 close, and the raw material of the electric cylinder part placed in it is stamped, bent or formed. After stamping is completed, the cylinder 5 retracts, pulling the moving plate 3 and the upper mold base 6 upward along the guide posts 2 to open the mold. Then, the formed electric cylinder part is taken out from the lower mold base 7, thus completing the processing. When the lower mold base 7 needs to be quickly installed, align the lower mold base 7 with the connecting seat 801 on the base 1, and simultaneously align the guide groove 803 on the lower mold base 7 with the guide post 802 on the connecting seat 801. Then, slowly lower it. When the guide post 802 is fully inserted into the guide groove 803 and the bottom of the lower mold base 7 is in contact with the surface of the connecting seat 801, align the slot 815 with the insert rod 814. Then, turn the circular handle 817 to rotate the rotating rod 804. The rotating rod 804 drives the first bevel gear 805 at its end to rotate, and the first bevel gear 805 drives the meshing... The second bevel gear 806 drives the adjusting rod 807 to rotate, causing the extrusion block 809, which is threaded to it, to move upward along the limiting rod 808. During the upward movement of the extrusion block 809, the inclined surfaces on both sides of it will press against the inclined surfaces of the two adjusting blocks 812, pushing the two adjusting blocks 812 to overcome the elastic force of the first spring 811 and move outward. The adjusting blocks 812 drive the connecting block 813 and the insert rod 814 to move outward, so that the insert rod 814 is steadily inserted into the slot 815 of the lower mold base 7 under the action of the guide block 816, thus completing the installation of the lower mold base 7. When it is necessary to disassemble the lower mold base 7, rotate the handle 817 in the reverse direction to rotate the rotating rod 804, which drives the first bevel gear 805, the second bevel gear 806, and the adjusting rod 807 to rotate, causing the extrusion block 809 to move downward along the limiting rod 808. At this time, the first spring 811 on the telescopic rod 810 returns to its original deformation, pushing the two adjusting blocks 812 to reset inward. The adjusting blocks 812 drive the connecting block 813 and the insert rod 814 to move inward, so that the insert rod 814 completely exits from the slot 815 of the lower mold base 7. Then, the lower mold base 7 can be removed upward. The disassembly and installation process of the upper mold base 6 is the same as described above.

[0026] When it is necessary to clean the residue on the lower mold base 7, push the movable frame 93 by hand, so that the movable frame 93 moves along the slide rail 91 with the slider 92, and at the same time moves the scraper 94. The scraper 94 is conical, which can clean better, and is made of stainless steel, which is more durable. The blade of the scraper 94 moves in close contact with the forming surface of the lower mold base 7 to scrape off the residue on the surface. After the cleaning action is completed, release your hand. The restoring force of the second spring 97 on the fixed rod 96 will push the movable frame 93 to automatically slide back to the initial position, which is convenient for the next cleaning and also prevents the scraper 94 from staying in the working area and obstructing other operations.

[0027] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
