Description

Technical Field

[0001] This utility model relates to the field of silicone injection molding machine technology, and in particular to a silicone injection molding device for quick mold changing. Background Technology

[0002] A silicone injection molding machine is a specialized injection molding machine for processing silicone materials. It features excellent insulation properties, resistance to high and low temperatures, resistance to vaporization aging, sterilization capabilities, and oil resistance, making it suitable for various fields such as electronics, medical, and oil and mining. During the silicone injection molding process, the injection mold is frequently changed as needed.

[0003] A Chinese utility model patent (CN222115866U) discloses a quick mold change device for an injection molding machine, comprising fixed plates and fixed rods. Two fixed plates are symmetrically arranged, and four fixed rods are fixedly connected between the two fixed plates. This utility model, by incorporating a positioning and locking assembly and a locking positioning assembly, allows the positioning rods to be inserted into their respective positioning slots under the action of springs when the positioning plate on the lower side of the mold is inserted into the bottom groove and the positioning plates on the left and right sides are inserted into the vertical grooves. This achieves positioning and locking between the mounting frame and the mold, facilitating mold installation. When mold disassembly is required, the mounting plate and mold are lifted using lifting rings, compressing the springs on the positioning rods and allowing for easy mold removal and replacement. This utility model offers advantages such as ease of replacement and improved installation accuracy. Referring to the quick mold change device of the aforementioned injection molding machine, the positioning rod used for positioning and fixing between the mold and the mounting frame during the rapid mold change process mainly relies on the passive pushing of the positioning rod when the mold moves, and then the elastic extension and contraction of the spring to assist in the mold assembly and disassembly. The positioning rod itself cannot actively move to assist in the assembly and disassembly of the mold. This makes the positioning rod susceptible to significant damage during the passive pushing process, shortening its service life and affecting the overall use of the injection mold. Therefore, how to better enable the positioning rod to actively move to cooperate with the assembly and disassembly of the injection mold is an important problem that needs to be solved in the design of the quick mold change silicone injection molding device. Utility Model Content

[0004] This invention provides a quick mold-changing silicone injection molding device to solve the problem that the positioning rod cannot move actively to assist in the assembly and disassembly of the mold.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0006] This utility model provides a quick mold-changing silicone injection molding device, including a mounting frame and a mounting plate, wherein an injection mold is slidably disposed within the mounting frame, and further includes:

[0007] A second snap-fit ​​fixing structure is provided inside the mounting frame;

[0008] A snap-fit ​​fixing structure one is provided inside the mounting plate. The snap-fit ​​fixing structure one and the snap-fit ​​fixing structure two cooperate with each other to position and fix the injection mold.

[0009] The clamping structure is provided to engage and fix both sides of the first structure.

[0010] Preferably, four fixing blocks are fixedly connected to the side walls on both sides of the mounting frame, and fixing rods are fixedly connected to the side walls of the four fixing blocks. Fixing plates are fixedly connected to both ends of the fixing rods, and hydraulic cylinders are fixedly connected to the side walls of the fixing plates.

[0011] Preferably, the side walls on both sides of the mounting frame are provided with a first insertion groove, a third sliding groove, and a fourth sliding groove. The side wall of the fourth sliding groove is provided with a fifth sliding groove. The bottom side wall of the mounting frame is provided with a third snap-fit ​​groove. The side wall of the mounting plate is provided with a second insertion groove, a first sliding groove, and a second sliding groove. The second insertion groove and the second sliding groove are interconnected. A support rod is fixedly connected to the inner side wall of the second sliding groove.

[0012] In this technical solution, the support rod limits the movement of the snap-fit ​​bracket, allowing it to move only laterally.

[0013] Preferably, a second insertion plate is fixedly connected to the inner sidewalls on both sides of the injection mold, the second insertion plate cooperates with the first insertion slot, and the sidewall of the second insertion plate is provided with a second snap-fit ​​groove. A first insertion plate is fixedly connected to the bottom sidewall of the injection mold, the first insertion plate cooperates with the third insertion slot, and a third insertion plate is fixedly connected to the top sidewall of the injection mold, the third insertion plate cooperates with the second insertion slot, and the sidewalls on both sides of the third insertion plate are provided with a first snap-fit ​​groove.

[0014] In this technical solution, plug-in plate 2 can be inserted into plug-in slot 1, plug-in plate 1 can be inserted into plug-in slot 3, and plug-in plate 3 can be inserted into plug-in slot 2.

[0015] Preferably, the second snap-fit ​​fixing structure includes a clamping rod, a second sliding block, a third spring, a third pushing block, and a first sliding frame. The clamping rod is slidably connected to the side walls on both sides of the mounting frame. The clamping rod extends through the third sliding groove and into the fourth sliding groove. The second sliding block is fixedly connected to the side wall of the clamping rod. The second sliding block is slidably connected to the third sliding groove. The third spring is fixedly connected between the second sliding block and the third sliding groove. The bottom of the clamping rod is fixedly connected to the third pushing block. The third pushing block is slidably connected to the fourth sliding groove. The bottom of the third pushing block is fixedly connected to the first sliding frame.

[0016] In this technical solution, when the clamping rod is no longer pressed, the compression spring three unfolds and pushes the sliding block two to rise. The sliding block two drives the clamping rod to rise and extend out of the side wall of the mounting frame. The clamping rod drives the push block to rise, and the push block drives the sliding frame one to rise.

[0017] Preferably, the second snap-fit ​​fixing structure includes a sliding rod, a connecting rod three, a sliding frame two, a sliding connecting block, a connecting rod four, and a fixing rod two. The sliding rod is slidably connected inside the sliding frame one. Both ends of the sliding rod are rotatably connected to one end of the connecting rod three, and the other end of the connecting rod three is rotatably connected to the sliding frame two. A sliding connecting block is fixedly connected to the side wall of the sliding frame two. The sliding connecting block has a "T" shaped structure and is slidably connected inside the sliding groove five. One end of the connecting rod four is rotatably connected to the side wall of the sliding frame two, and the other end of the connecting rod four is rotatably connected to the fixing rod two.

[0018] In this technical solution, the sliding frame 1 rises, causing the connecting rods 3 and 4 to rotate. The sliding frame 2 slides upward along the sliding groove 5. The connecting rod 4 pulls the locking block away from the locking groove 2 and retracts into the sliding groove 4, no longer restricting the movement of the plug plate 2.

[0019] Preferably, the second snap-fit ​​fixing structure includes a snap-fit ​​block, a limiting rod, a limiting groove, and a spring four. The limiting rod is fixedly connected to the inner side wall of the sliding groove four. The limiting groove is provided on the side wall of the snap-fit ​​block. The limiting rod is slidably connected in the limiting groove. The spring four is fixedly connected between the snap-fit ​​block and the inner side wall of the sliding groove four. The fixing rod two is fixedly connected to the side walls on both sides of the snap-fit ​​block. The snap-fit ​​block and the snap-fit ​​groove two cooperate with each other.

[0020] In this technical solution, the limiting rod limits the movement of the locking block, so that it can only move along the limiting rod. When the stretched spring retracts, it can work with the connecting rod to pull the locking block away from the locking groove.

[0021] Preferably, the snap-fit ​​fixing structure includes a second lifting ring, a second fixing block, a connecting block, a third fixing block, a second connecting rod, a snap-fit ​​frame, and a second spring. The connecting block is slidably connected to the side wall of the mounting plate. The top of the connecting block is fixedly connected to the second fixing block. The second lifting ring is fixedly connected to the second fixing block. The bottom of the connecting block is fixedly connected to the third fixing block. The second connecting rod is rotatably connected between the third fixing blocks. The other end of the second connecting rod is rotatably connected to the snap-fit ​​frame. The snap-fit ​​frame is slidably connected to the support rod. The second spring is fixedly connected between the snap-fit ​​frame and the inner side walls on both sides of the sliding groove. The snap-fit ​​frame and the snap-fit ​​groove cooperate with each other. The position of the second connecting rod is staggered from the position of the support rod.

[0022] In this technical solution, pressing down on the fixing block 2 causes the connecting block to descend, which in turn causes the fixing block 3 to descend. The fixing block 3 then causes the connecting rod 2 to move, which in turn pushes the snap-fit ​​bracket to move to both sides. The spring 2 is compressed, causing the snap-fit ​​bracket to disengage from the snap-fit ​​slot 1 and no longer restrict the plug-in plate 3, thus allowing the injection mold to be easily removed from the mounting plate.

[0023] Preferably, the clamping structure includes a lifting ring, a connecting rod, a sliding block, a clamping block, and a spring. The connecting rod is slidably connected to the side wall of the mounting plate. The top of the connecting rod is fixedly connected to the lifting ring, and the bottom of the connecting rod is fixedly connected to the sliding block. The sliding block is slidably connected within a sliding groove, and the bottom of the sliding block is fixedly connected to the clamping block. The clamping block is slidably connected to the side wall at the bottom of the sliding groove. A spring is fixedly connected between the sliding block and the inner side wall of the sliding groove.

[0024] In this technical solution, when the lifting ring rises, it drives the connecting rod to rise, which in turn pulls the sliding block to rise. The spring is compressed, and the sliding block drives the abutment block to rise, so the abutment block no longer presses against the abutment rod.

[0025] Preferably, the abutting block is directly opposite the abutting rod, and the height of the first lifting ring is lower than the height of the second lifting ring.

[0026] In this technical solution, the lifting ring is first pulled up during hoisting.

[0027] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0028] The positive and progressive effects of this utility model are as follows:

[0029] 1. Using external hoisting equipment, hooks are used to lift rings one and two. Lifting ring one is pulled upwards first, causing the clamping block to rise. The clamping block no longer presses against the clamping rod, compressing spring three unfolds, and stretching spring four retracts, causing the clamping rod to extend out of the side wall of the mounting frame. The locking block disengages from locking groove two, no longer restricting the movement of the insertion plate two. The hoisting equipment then rises, lifting the injection mold away from the mounting frame. The injection mold is then lowered, and fixing block two is pressed down, causing the locking bracket to disengage from locking groove one, thus allowing the injection mold to... The mold is removed from the mounting plate, replaced with a new injection mold, and then the second fixing block is released. The second compressed spring unfolds, and the snap-fit ​​bracket is pushed back into the snap-fit ​​groove one. The mounting plate and injection mold are lifted again and placed into the mounting frame. The first and second lifting rings are removed from the lifting equipment. The first compressed spring unfolds and pushes the abutment block down. The abutment block pushes the abutment rod down. The abutment rod pushes the snap-fit ​​block back into the snap-fit ​​groove two, thus positioning and fixing the injection mold, which facilitates the quick disassembly and mold replacement of the silicone injection molding device.

[0030] 2. When the clamping structure of this application rises, the second snap-fit ​​fixing structure unfolds, causing the snap-fit ​​block to actively disengage from the second snap-fit ​​groove, thus ceasing to position and fix the injection mold. When the clamping structure descends, the second snap-fit ​​fixing structure is pushed by the clamping structure, causing the second snap-fit ​​block to actively extend out and snap into the second snap-fit ​​groove, positioning and fixing the injection mold. This facilitates the assembly and disassembly of the injection mold by actively moving the snap-fit ​​block to cooperate with the mold. While not affecting the rapid disassembly of the injection mold, this design can effectively reduce damage to the snap-fit ​​block and extend its service life. Attached Figure Description

[0042] The clamping structure 11 is provided to engage and fix the two sides of the first fixing structure 12.

[0043] Four fixing blocks 4 are fixedly connected to the side walls on both sides of the mounting frame 5. Fixing rods 3 are fixedly connected to the side walls of the four fixing blocks 4. Fixing plates 1 are fixedly connected to both ends of the fixing rods 3. Hydraulic cylinders 2 are fixedly connected to the side walls of the fixing plates 1.

[0044] The mounting frame 5 has a first insertion groove 17, a third sliding groove 18, and a fourth sliding groove 20 on its two side walls. The fourth sliding groove 20 has a fifth sliding groove 21 on its side wall. The bottom side wall of the mounting frame 5 has a third snap-fit ​​groove. The mounting plate 7 has a second insertion groove 23, a first sliding groove 14, and a second sliding groove 15 on its side wall. The second insertion groove 23 and the second sliding groove 15 are interconnected. A support rod 16 is fixedly connected to the inner side wall of the second sliding groove 15.

[0045] The support rod 16 limits the movement of the snap-fit ​​bracket 1206, allowing it to move only laterally.

[0046] The inner sidewalls on both sides of the injection mold 6 are fixedly connected to the second insertion plate 9, which cooperates with the first insertion slot 17. The sidewall of the second insertion plate 9 is provided with the second snap-fit ​​slot 22. The bottom sidewall of the injection mold 6 is fixedly connected to the first insertion plate 8, which cooperates with the third insertion slot 24. The top sidewall of the injection mold 6 is fixedly connected to the third insertion plate 10, which cooperates with the second insertion slot 23. The sidewalls on both sides of the third insertion plate 10 are provided with the first snap-fit ​​slot 13.

[0047] Plug-in board 29 can be inserted into plug-in slot 17, plug-in board 18 can be inserted into plug-in slot 3 24, and plug-in board 3 10 can be inserted into plug-in slot 23.

[0048] The snap-fit ​​fixing structure 19 includes a clamping rod 1901, a sliding block 1902, a spring 1903, a pushing block 1904, and a sliding frame 1905. The clamping rod 1901 is slidably connected to the side walls on both sides of the mounting frame 5. The clamping rod 1901 extends through the sliding groove 18 and into the sliding groove 20. The sliding block 1902 is fixedly connected to the side wall of the clamping rod 1901. The sliding block 1902 is slidably connected in the sliding groove 18. The spring 1903 is fixedly connected between the sliding block 1902 and the sliding groove 18. The bottom of the clamping rod 1901 is fixedly connected to the pushing block 1904. The pushing block 1904 is slidably connected in the sliding groove 20. The bottom of the pushing block 1904 is fixedly connected to the sliding frame 1905.

[0049] When the clamping rod 1901 is no longer compressed, the compression spring 3 1903 unfolds and pushes the sliding block 2 1902 to rise. The sliding block 2 1902 drives the clamping rod 1901 to rise and extend out of the side wall of the mounting frame 5. The clamping rod 1901 drives the push block 1904 to rise, and the push block 1904 drives the sliding frame 1 1905 to rise.

[0050] The snap-fit ​​fixing structure 219 includes a sliding rod 1911, a connecting rod 3 1912, a sliding frame 2 1913, a sliding connecting block 1914, a connecting rod 4 1915, and a fixing rod 2 1916. The sliding rod 1911 is slidably connected to the sliding frame 1 1905. Both ends of the sliding rod 1911 are rotatably connected to one end of the connecting rod 3 1912. The other end of the connecting rod 3 1912 is rotatably connected to the sliding frame 2 1913. A sliding connecting block 1914 is fixedly connected to the side wall of the sliding frame 2 1913. The sliding connecting block 1914 has a "T" shaped structure and is slidably connected to the sliding groove 5 21. One end of the connecting rod 4 1915 is rotatably connected to the side wall of the sliding frame 2 1913. The other end of the connecting rod 4 1915 is rotatably connected to the fixing rod 2 1916.

[0051] The sliding frame 1905 rises, causing the connecting rods 312 and 415 to rotate. The sliding frame 213 slides upward along the sliding groove 521. The connecting rod 415 pulls the locking block 1921 out of the locking groove 22 and retracts into the sliding groove 420, no longer restricting the movement of the plug plate 29.

[0052] The second snap-fit ​​fixing structure 19 includes a snap-fit ​​block 1921, a limiting rod 1922, a limiting groove 1923, and a spring 1924. The limiting rod 1922 is fixedly connected to the inner side wall of the sliding groove 20. The limiting groove 1923 is provided on the side wall of the snap-fit ​​block 1921. The limiting rod 1922 is slidably connected in the limiting groove 1923. The spring 1924 is fixedly connected between the snap-fit ​​block 1921 and the inner side wall of the sliding groove 20. The second fixing rod 1916 is fixedly connected to the side walls on both sides of the snap-fit ​​block 1921. The snap-fit ​​block 1921 and the second snap-fit ​​groove 22 cooperate with each other.

[0053] The limiting rod 1922 limits the movement of the locking block 1921, so that it can only move along the limiting rod 1922. When the stretched spring 1924 retracts, it can work with the connecting rod 1915 to pull the locking block 1921 out of the locking groove 22.

[0054] The snap-fit ​​fixing structure 12 includes a second lifting ring 1201, a second fixing block 1202, a connecting block 1203, a third fixing block 1204, a second connecting rod 1205, a snap-fit ​​bracket 1206, and a second spring 1207. The connecting block 1203 is slidably connected to the side wall of the mounting plate 7. The top of the connecting block 1203 is fixedly connected to the second fixing block 1202, the second lifting ring 1201 is fixedly connected to the second fixing block 1202, and the bottom of the connecting block 1203 is fixedly connected to the third fixing block 1207. 204, a connecting rod 1205 is rotatably connected between the three fixed blocks 1204, and the other end of the connecting rod 1205 is rotatably connected to the snap-fit ​​bracket 1206. The snap-fit ​​bracket 1206 is slidably connected to the support rod 16. A spring 1207 is fixedly connected between the snap-fit ​​bracket 1206 and the inner sidewalls on both sides of the sliding groove 15. The snap-fit ​​bracket 1206 and the snap-fit ​​groove 13 cooperate with each other. The position of the connecting rod 1205 is offset from the position of the support rod 16.

[0055] Pressing down on fixing block 2 1202 causes fixing block 2 1202 to drive connecting block 1203 to descend, connecting block 1203 drives fixing block 3 1204 to descend, fixing block 3 1204 drives connecting rod 2 1205 to move, connecting rod 2 1205 pushes snap-fit ​​bracket 1206 to move to both sides, spring 2 1207 is compressed, causing snap-fit ​​bracket 1206 to disengage from snap-fit ​​groove 13 and no longer restrict the plug-in plate 3 10, which can better allow the injection mold 6 to be removed from the mounting plate 7.

[0056] The clamping structure 11 includes a lifting ring 1101, a connecting rod 1102, a sliding block 1103, a clamping block 1104, and a spring 1105. The connecting rod 1102 is slidably connected to the side wall of the mounting plate 7. The top of the connecting rod 1102 is fixedly connected to the lifting ring 1101, and the bottom of the connecting rod 1102 is fixedly connected to the sliding block 1103. The sliding block 1103 is slidably connected in the sliding groove 14, and the bottom of the sliding block 1103 is fixedly connected to the clamping block 1104. The clamping block 1104 is slidably connected to the side wall at the bottom of the sliding groove 14. A spring 1105 is fixedly connected between the sliding block 1103 and the inner side wall of the sliding groove 14.

[0057] The lifting ring 1101 rises, causing the connecting rod 1102 to rise. The connecting rod 1102 pulls the sliding block 1103 to rise, the spring 1105 is compressed, and the sliding block 1103 causes the abutment block 1104 to rise. The abutment block 1104 no longer abuts the abutment rod 1901.

[0058] The clamping block 1104 is directly opposite the clamping rod 1901, and the height of the first lifting ring 1101 is lower than the height of the second lifting ring 1201.

[0059] This causes the lifting ring 1101 to be pulled up first during hoisting.

[0060] When using this utility model, during mold changing, the lifting ring 1101 and the lifting ring 1201 are hooked by an external lifting device for lifting. The lifting ring 1101 is pulled up first, and the lifting ring 1101 drives the connecting rod 1102 to rise. The connecting rod 1102 pulls the sliding block 1103 to rise, the spring 1105 is compressed, and the sliding block 1103 drives the abutting block 1104 to rise. The abutting block 1104 no longer abuts the abutting rod 1901.

[0061] The compression spring 1903 unfolds and pushes the sliding block 1902 to rise. The sliding block 1902 drives the clamping rod 1901 to rise and extend out of the side wall of the mounting frame 5. The clamping rod 1901 drives the push block 1904 to rise. The push block 1904 drives the sliding frame 1905 to rise. The connecting rod 1912 and the connecting rod 1915 rotate. The sliding frame 1913 slides upward along the sliding groove 21. The stretched spring 1924 retracts. In conjunction with the connecting rod 1915, it pulls the locking block 1921 to disengage from the locking groove 22 and retract into the sliding groove 20. It no longer restricts the movement of the plug plate 29. At this time, the height of the lifting ring 1101 moves to be level with the lifting ring 2201.

[0062] The hoisting equipment then rises, and lifting ring 1101 and lifting ring 2 1201 are pulled upwards simultaneously. When lifting ring 2 1201 is pulled upwards, connecting block 1203 cannot move downwards. Even during the hoisting process, snap-fit ​​bracket 1206 is always snapped into snap-fit ​​groove 13, thereby fixing injection mold 6 to the bottom of mounting plate 7. Mounting plate 7 rises, causing injection mold 6 to rise and detach from mounting frame 5. Then, injection mold 6 is lowered, and fixing block 2 1202 is pressed downwards. Fixing block 2 1202 causes connecting block 1203 to descend, and connecting block 1203 causes fixing block 3 1204 to descend. Fixing block 3 1204 causes connecting rod 2 1205 to move, and connecting rod 2 1205 pushes snap-fit ​​bracket 1206 to move to both sides. Spring 2 1207 is compressed, causing snap-fit ​​bracket 1206 to detach from snap-fit ​​groove 13 and no longer restricting plug plate 3 10. This allows injection mold 6 to be easily removed from mounting plate 7.

[0063] Replace the injection mold 6 with a new one, then release the fixing block 1202, the compressed spring 1207 unfolds, and push the snap-fit ​​bracket 1206 back into the snap-fit ​​groove 13. Lift the mounting plate 7 and injection mold 6 again and place them into the mounting frame 5, so that the plug-in plate 9 inserts into the plug-in groove 17 and the plug-in plate 8 inserts into the plug-in groove 34. Remove the lifting rings 1101 and 1201 from the lifting equipment. The compressed spring 1105 unfolds and pushes the sliding block 1103 down. Sliding block 1103 drives the clamping block 1104 to descend, the clamping block 1104 pushes the clamping rod 1901 to descend, the clamping rod 1901 drives the pushing block 1904 to descend, the pushing block 1904 pushes the connecting rod 3 1912 and the connecting rod 4 1915 to rotate, the sliding frame 2 1913 slides down along the sliding groove 5 21, pushes the locking block 1921 to re-lock into the locking groove 2 22, and positions and fixes the injection mold 6, which facilitates the quick assembly and disassembly of the injection mold 6.

[0064] This utility model is not limited to the above-described embodiments. Any changes in its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
