Technical Field
[0001] This utility model belongs to the technical field of mold installation structure, and in particular relates to a mold installation structure for a multi-station injection molding machine. Background Technology
[0002] The mold installation structure of a multi-station injection molding machine refers to the method and components for installing molds on the multi-station injection molding machine. When fixing the mold, methods include hoisting, direct placement, using mold clamps, and using pressure plates. Therefore, it can be seen that the existing mold installation structure basically meets people's usage needs, but the following problems still exist.
[0003] When operators install molds on injection molding machines using the direct placement method, the molds are typically heavy, so hoisting equipment may be used to lift them for placement within the machine. During this process, operators place a pad on the platform to increase the mold's height and create a gap between the mold and the platform, facilitating easy disassembly using the hoisting equipment. However, once the mold is placed on the pad, its weight can make fine adjustments difficult, potentially hindering the operator from moving the mold. Therefore, we propose a mold installation structure for a multi-station injection molding machine. Utility Model Content
[0004] This utility model provides a mold installation structure for a multi-station injection molding machine. After the fixed block drives the ball to pass through the pad body, when the operator pushes the mold to slide on the surface of the pad body, the mold rolls on the surface of the ball, reducing the friction between the mold and the pad body and improving the convenience of the operator to push the mold for micro-adjustment.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold installation structure for a multi-station injection molding machine, comprising a pad body, a cavity groove in the middle of the pad body, and a connecting plate slidably connected to the inner wall of the cavity groove. A pull rod penetrating one side of the pad body is fixed to one end of each connecting plate. Several sets of first abutments are fixed to the surface of each connecting plate, and the first abutments and second abutments are in contact with each other. A fixing block embedded in the cavity groove is fixed to the end of each second abutment. Several sets of ball grooves are opened in the middle of each fixing block, and rolling balls are embedded in each ball groove. The rolling balls pass through the upper end of the pad body.
[0006] Furthermore, a first extension rod and a second extension rod are respectively fixed between the two sets of pad bodies, and the surface of the second extension rod is provided with a guide groove opened on the first extension rod. A slider is fixed on the side of the second extension rod and the first extension rod that are in contact with each other, and the surface of the slider is provided with a sliding groove opened in the middle of the first extension rod. A screw block is provided between the two sets of first extension rods, and connecting rods are symmetrically fixed on both sides of the screw block. The ends of the connecting rods are elastically connected to traction rods, and the ends of the traction rods are fixed with bolts. The bolts all pass through the sliding grooves, and the ends of the bolts are provided with threaded grooves opened in the middle of the sliders.
[0007] Furthermore, each of the traction rods has a traction groove formed on the connecting rod, and each traction groove has a spring embedded in it, which abuts against the surface of the traction rod and the inner wall of the traction groove.
[0008] Furthermore, each of the traction rods is fitted with an extension sleeve, and the extension sleeve is fixed at the opening of the traction groove.
[0009] Furthermore, all the traction rods are configured as rectangular blocks, and all the traction grooves are configured as rectangular grooves that match the rectangular blocks on the traction rods.
[0010] Furthermore, each of the pull rods is fixed with a pull plate at its end, and the surface of the pull plate is provided with several sets of wavy grooves.
[0011] Furthermore, each cavity groove is fixed with a retaining ring.
[0012] Furthermore, guide grooves are symmetrically provided on both ends of the connecting plate, and guide rods fixed to the inner wall of the fixing block are inserted into the middle of each guide groove.
[0013] The beneficial effects of this utility model are:
[0014] 1. The mold mounting structure of this multi-station injection molding machine is equipped with a fixed block, a rolling ball, a cavity groove, and a ball groove. The first abutment block pushes the second abutment block to move, which in turn pushes the fixed block to move. The fixed block drives the rolling ball to move through the ball groove, causing the rolling ball to move out of the pad block body. When the operator pushes the mold to slide on the surface of the pad block body, the mold pushes the rolling ball to move, and the rolling ball rolls in the ball groove, reducing the friction between the pad block body and the mold and improving the convenience for the operator to push the mold for micro-adjustment.
[0015] 2. The mold mounting structure of this multi-station injection molding machine is equipped with a first extension rod, a slide groove, a second extension rod, and a slider. The second extension rod slides within the guide groove, and the second extension rod drives the slider to slide within the slide groove, increasing the gap between the two sets of pad blocks. This facilitates adjustment of the gap between the two sets of pad blocks, allowing them to support molds of different sizes. Furthermore, connecting the two sets of pad blocks together makes it easy to align and place them together, improving the operator's usability. Attached Figure Description

[0028] To further understand the utility model's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0029] Example:
[0030] Please see Figure 1 - Figure 10 A mold mounting structure for a multi-station injection molding machine includes a pad body 1. A cavity groove 2 is formed in the middle of the pad body 1, and a connecting plate 18 is slidably connected to the inner wall of the cavity groove 2. A pull rod 22, penetrating one side of the pad body 1, is welded to one end of each connecting plate 18. Several sets of first abutment blocks 19 are welded to the surface of each connecting plate 18, and the first abutment blocks 19 and second abutment blocks 21 are in contact with each other. A fixing block 24, embedded in the cavity groove 2, is welded to the end of each second abutment block 21. Several sets of ball grooves 4 are formed in the middle of each fixing block 24, and each ball groove 4 contains a rolling ball 3, which passes through the upper end of the pad body 1. When the operator sets up the mold, the operator first places two sets of pad bodies 1 on the injection molding machine. Then, the operator pulls a pull plate 23, which moves the pull rod 22, causing the connecting plate 18 to move, thus moving the first abutment blocks 19. When the first abutment block 19 moves, the inclined slope of the surface of the first abutment block 19 matches the inclined slope of the second abutment block 21. As the first abutment block 19 moves continuously, it pushes the second abutment block 21 to move. When the second abutment block 21 moves, it pushes the fixed block 24 to move. The fixed block 24 pushes the ball groove 4 to move, which in turn pushes the rolling ball 3 to move, pushing the rolling ball 3 out of the fixed block 24. Then, the operator places the mold on the surface of the pad body 1, so that the mold and the surface of the rolling ball 3 are in contact. The operator pushes the mold to move, and the mold and the rolling ball 3 are in contact. When the mold moves, it pushes the rolling ball 3 to rotate in the ball groove 4, which reduces the friction between the mold and the surface of the pad body 1, improves the stability of the mold sliding on the surface of the pad body 1, and facilitates the operator to make fine adjustments to the mold.
[0031] In other embodiments, a first extension rod 7 and a second extension rod 9 are welded between the two sets of pad bodies 1, and the surface of the second extension rod 9 is provided with a guide groove 13 opened on the first extension rod 7. A slider 10 is welded to the side of the second extension rod 9 that is in contact with the first extension rod 7, and the surface of the slider 10 is provided with a sliding groove 8 opened in the middle of the first extension rod 7. A screw block 5 is provided between the two sets of first extension rods 7, and connecting rods 6 are symmetrically welded to the two ends of the screw block 5. The ends of the connecting rods 6 are elastically connected to a traction rod 14. All surfaces of the traction rod 14 are fitted with traction grooves 15 formed on the connecting rod 6. Each traction groove 15 contains a spring 16 that abuts against the surface of the traction rod 14 and the inner wall of the traction groove 15. Bolts 11 are welded to the ends of the traction rods 14, and each bolt 11 passes through the sliding groove 8. A threaded groove 12 is fitted at the end of the bolt 11 in the middle of the slider 10. When the operator needs to adjust the gap between the two sets of pad bodies 1, the operator places a wrench on the surface of the screw block 5, making the plate fit against the hexagonal shape on the surface of the screw block 5. Then the operator... By pushing the tightening block 5 with a wrench, the tightening block 5 drives the connecting rod 6 to rotate. As the connecting rod 6 rotates, it drives the traction rod 14 to move via the traction groove 15. When the traction rod 14 moves, it drives the bolt 11 to move, causing the bolt 11 to engage with the threaded groove 12, thus preventing the bolt 11 from abutting against the surface of the first extension rod 7. Next, the operator pulls the two sets of pad bodies 1 to move, which in turn drives the first extension rod 7 and the second extension rod 9 to move, causing the first extension rod 7 to slide... The groove 8 slides on the surface of the slider 10, causing the first extension rod 7 to separate from the groove 8. After the two sets of pad bodies 1 move to the appropriate distance, the operator turns the screw block 5 again. The screw block 5 drives the traction groove 15 to move through the connecting rod 6. The traction groove 15 drives the traction rod 14 to move. The traction rod 14 drives the bolt 11 to engage with the threaded groove 12, so that the bolt 11 abuts against the surface of the first extension rod 7, thus fixing the first extension rod 7 and the second extension rod 9 to each other, making it convenient for the operator to fix and install the first extension rod 7 and the second extension rod 9.
[0032] Secondly, the threads of the two sets of bolts 11 and threaded grooves 12 are opposite.
[0033] In other embodiments, an extension sleeve 17 is fitted on the surface of the traction rod 14, and the extension sleeve 17 is welded to the opening of the traction groove 15. After the extension sleeve 17 is fitted on the surface of the traction rod 14, the extension sleeve 17 is fixed at the opening of the traction groove 15, so that the extension sleeve 17 increases the contact area of the traction rod 14 moving through the traction groove 15 and increases the stability of the traction rod 14 moving at the opening of the traction groove 15.
[0034] In other embodiments, the traction rod 14 is configured as a rectangular block, and the traction groove 15 is configured as a rectangular groove that matches the rectangular block of the traction rod 14. By matching the rectangular block of the traction rod 14 with the rectangular groove of the traction groove 15, the rectangular block of the traction rod 14 can slide within the rectangular groove of the traction groove 15. When the connecting rod 6 drives the traction rod 14 to rotate through the traction groove 15, the inner wall of the rectangular groove of the traction groove 15 abuts against the surface of the traction rod 14, which is configured as a rectangular block, so that the traction groove 15 drives the traction rod 14 to move.
[0035] In other embodiments, a pull plate 23 is welded to the end of each pull rod 22, and the surface of each pull plate 23 is provided with several sets of wavy grooves. When the operator pulls the connecting plate 18 to move it, the operator first holds the surface of the pull plate 23 with his hand, and then the operator pulls the pull plate 23. The pull plate 23 drives the pull rod 22 to move, and the pull rod 22 drives the connecting plate 18 to move, which makes it convenient for the operator to pull the connecting plate 18 to move. When the operator holds the surface of the pull plate 23 with his hand, the operator's hand and the several sets of wavy grooves on the surface of the pull plate 23 fit together, increasing the friction between the operator's hand and the surface of the pull plate 23, thereby improving the stability of the operator pulling the pull plate 23.
[0036] In other embodiments, a fixing ring 20 is welded inside the cavity groove 2. By fixing the fixing ring 20 to the inner wall of the cavity groove 2, after the second abutment 21 and the first abutment 19 no longer support the fixing block 24, the fixing block 24 slides downward in the cavity groove 2, and the fixing ring 20 supports the fixing block 24, so as to prevent the fixing block 24 from being completely pressed against the surface of the first abutment 19, which would prevent the first abutment 19 from pushing the fixing block 24 to move through the second abutment 21, thus improving the usability for the operator.
[0037] In other embodiments, guide grooves 26 are symmetrically provided on both ends of the connecting plate 18, and guide rods 25 welded to the inner wall of the fixing block 24 are inserted into the middle of each guide groove 26. When the connecting plate 18 moves, the connecting plate 18 drives the guide grooves 26 to slide on the surface of the guide rods 25, so that the guide rods 25 and the guide grooves 26 pull the connecting plate 18, thereby increasing the stability of the movement of the connecting plate 18.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
