DETAILED DESCRIPTION

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Specific examples are given below.

[0026] like Figures 1 to 5As shown, the sole injection molding device described in the embodiment of the utility model includes a table top 1; the top surface of the table top 1 is fixedly connected to a support column 11; the top of the support column 11 is fixedly connected to a support plate 12; the top of the support plate 12 is fixedly connected to a first motor 13; the output end of the first motor 13 is rotatably connected to an electric push rod 14; the bottom of the electric push rod 14 is fixedly connected to a connecting block 15; the bottom of the connecting block 15 is slidably connected to a shoe mold 16; the top of the shoe mold 16 is provided with an injection hole 17; the inside of the shoe mold 16 is provided with a plurality of injection channels 18; the bottom of the shoe mold 16 is provided with a clamping block 19; the inside of the clamping block 19 is fixedly connected to The shoe mold 110 is connected, and two injection paths 18 are provided inside the shoe mold 16; the two injection paths 18 are respectively located in the middle and rear parts of the shoe mold 16. When working, the device is first placed at a designated location. When it is necessary to perform injection molding on a plastic part, the prepared shoe mold 16 is first placed inside the connecting block 15, and then the first motor 13 is started. After the first motor 13 is started, the electric push rod 14 is driven to perform lifting and lowering adjustment. When it is necessary to perform injection molding on a plastic part, the shoe mold 16 is adjusted downward, and then the connecting block 15 is driven to descend by the electric push rod 14. When the connecting block 15 descends, the shoe mold 16 will also descend. When it descends to a point where it is almost aligned with the shoe mold 110, the shoe mold 16 is moved downward. When the shoe mold 110 is in contact, the clamping block 19 is pushed. When the clamping block 19 is pushed, the distance between the sole mold 110 and the clamping block 19 is shortened until the clamping block 19 is completely closed, and the sole mold 110 can be fixed. After the sole mold 110 is fixed, the first motor 13 is started again to drive the connecting block 15 and the shoe mold 16 to descend again through the electric push rod 14 until the shoe mold 16 contacts the sole mold 110, and the lifting adjustment of the shoe mold 16 is completed. After the adjustment is completed, the prepared injection molding material can be injected from the injection molding hole 17. After the injection molding material enters the interior of the injection molding hole 17, the injection molding material will flow along the injection molding path 18 toward the sole until it flows into the top surface of the sole mold 110 according to the actual The amount of injection material is controlled according to the actual situation. After the injection molding is completed, the injection molding material needs to be cooled and solidified. After cooling and solidification, the first motor 13 is started again to drive the electric push rod 14 and the connecting block 15 to make it rise. After rising to the appropriate position, the clamping block 19 is pushed open to remove the plastic part for use. Through the above structure, when injecting the plastic part, the first motor 13 drives the electric push rod 14 to adjust the lifting and lowering of the shoe mold 16 for the convenience of personnel during use. At the same time, a plurality of injection molding channels 18 are provided inside the shoe mold 16, which distributes the injection molding material more evenly to the sole mold 110 during injection, reducing the defects of the plastic parts caused by uneven flow of the injection molding material, thereby reducing the quality of the plastic parts and improving production efficiency.

[0027] like Figures 1 to 2As shown, the top surface of the table top 1 is fixedly connected to the hinge shaft 22; the side wall of the hinge shaft 22 is rotatably connected to the first splint 2; the side wall of the hinge shaft 22 is rotatably connected to the second splint 21; the second splint 21 and the hinge shaft 22 are located on the top surface of the table top 1; the top surface of the first splint 2 is fixedly connected to the first handle 23; the side wall of the support column 11 is rotatably connected to the clamping block 24; the side wall of the clamping block 24 is fixedly connected to the second handle 25. During operation, the plastic part needs to be injection molded after the clamping block 19 is closed. During the injection molding of the plastic part, the clamping block 19 is prone to loosening, which will cause the sole mold 110 to become loose or even incorrectly positioned, which will affect the injection molding of the plastic part. To reduce this situation, first hold the first handle 23 and push it in the direction of the shoe mold 16. After pushing the first handle 23, the first handle 23 pushes the first splint 2, At the same time, the first plywood 2 will push the clamping block 19 until the clamping block 19 contacts to complete the fixation of the sole mold 110, and then the second handle 25 will be rotated toward the first plywood 2 or the second plywood 21 until the clamping block 24 contacts the first plywood 2 or the second plywood 21, thereby further fixing the sole mold 110. When the cooled plastic part needs to be removed, the second handle 25 is rotated in the opposite direction to make the clamping block 24 move away from the first plywood 2 or the second plywood 21, and then the sole mold 110 will become loose. When pushing the first handle 23, the first handle 23 can be easily pushed by the hinge shaft 22. Through the above structure, it is convenient to further fix the clamping block 19 by pushing the first plywood 2 and the second plywood 21 when the sole mold 110 is in use, thereby reducing the situation where loosening occurs during injection molding of the plastic part and causes injection molding failure, and at the same time reducing the loss of injection molding material.

[0028] like Figures 1 to 3 As shown, the bottom surface of the support plate 12 is fixedly connected to the connecting plate 3; the side wall of the connecting plate 3 is fixedly connected to the heat dissipation box 31; the side wall of the heat dissipation box 31 is fixedly connected to the second motor 32; the output end of the second motor 32 is fixedly connected to the rotating shaft 33; the end of the rotating shaft 33 is rotatably connected to the connecting column 34; the side wall of the connecting column 34 is fixedly connected to a plurality of blades 35. During operation, after the injection molding is completed, the second motor 32 can be started to reduce the cooling time. After the second motor 32 is started, it drives the rotating shaft 33 to rotate and then drives the connecting column 34 to rotate. After the connecting column 34 rotates, it drives the blades 35 to move to dissipate heat for the injection molding, which can shorten the cooling time of the plastic part, thereby improving production efficiency. Through the above structure, the time for plastic part molding is reduced by dissipating heat to the plastic part, thereby improving production efficiency.

[0029] like Figures 1 to 2As shown, a groove 4 is provided on the side wall of the connecting block 15; a threaded rod 41 is slidably connected to the inside of the groove 4; an adjusting nut 42 is rotatably connected to the side wall of the threaded rod 41. During operation, when the shoe mold 16 is placed inside the connecting block 15, the shoe mold 16 may slide out of the connecting block 15, resulting in the inability to align the shoe mold 16 with the sole mold 110 and thus the inability to inject the plastic part. At this time, the threaded rod 41 is slidably adjusted inside the groove 4, adjusted to a suitable position, and then the adjusting nut 42 is rotated to fix the threaded rod 41 inside the groove 4. Through the above structure, the position of the shoe mold 16 can be easily adjusted to enable more accurate injection molding of the plastic part.

[0030] like Figures 1 to 5 As shown, the bottom of the table top 1 is fixedly connected to a lifting rod 5; the inside of the lifting rod 5 is fixedly connected to a spring 51; the side wall of the spring 51 is fixedly connected to a button 52. During operation, when the device is used in different areas, different heights of the areas may be encountered, which may make it inconvenient to use the device. When a higher area is encountered, the button 52 can be pressed, and the button 52 will squeeze the spring 51. The button 52 will be retracted into the inside of the lifting rod 5, and then the device can be pressed down to descend. At the same time, when a lower area is encountered, the button 52 can be pressed, and the button 52 will squeeze the spring 51. The button 52 will be retracted into the inside of the lifting rod 5, and then the device can be lifted to ascend. Through the above structure, it is beneficial to adjust the lifting and lowering of the device when different heights are encountered in different areas.

[0031] like Figures 1 to 2 As shown, the bottom surface of the support plate 12 is fixedly connected to a fixed block 6; a slide groove 61 is provided inside the fixed block 6. During operation, when the sole is injected, the plastic part to be injected can be slid inside the fixed block 6 through the slide groove 61 to facilitate injection molding of the plastic part to be injected. At the same time, the plastic part can be easily taken out for injection molding through the slide groove 61. Through the above structure, the plastic part to be injected can be easily stored and collected.

[0032] like Figures 1 to 5 As shown, the bottom of the lifting rod 5 is fixedly connected to an anti-slip pad 7; the anti-slip pad 7 is made of flexible material. When working, the anti-slip pad 7 can play an anti-slip role when the device is placed, thereby reducing the slipping phenomenon when the device is used, and then causing damage to the device. Through the above structure, the device can be effectively prevented from slipping during work and causing damage to it.

[0033] During operation, the device is first placed at a designated location. When it is necessary to perform injection molding on a plastic part, the prepared shoe mold 16 is first placed inside the connecting block 15, and then the first motor 13 is started. After the first motor 13 is started, the electric push rod 14 is driven to perform lifting and lowering adjustment. When the plastic part is to be injection molded, the shoe mold 16 is adjusted downward, and then the connecting block 15 is driven to descend by the electric push rod 14. When the connecting block 15 descends, the shoe mold 16 will also descend. When it descends to the point where it is almost in contact with the sole mold 110, the clamping block 19 is pushed. When pushing the clamping block 19, the distance between the sole mold 110 and the clamping block 19 is shortened until the clamping block 19 is completely closed, and the sole mold 110 can be fixed. After the sole mold 110 is fixed, the first motor 13 is started again to drive the connecting block 16 through the electric push rod 14. The connecting block 15 and the shoe mold 16 are lowered again until the shoe mold 16 contacts the sole mold 110, and the lifting and lowering adjustment of the shoe mold 16 is completed. After the adjustment, the prepared injection molding material can be injected from the injection hole 17. After the injection molding material enters the interior of the injection molding hole 17, the injection molding material will flow along the injection molding path 18 toward the sole until it flows into the top surface of the sole mold 110. The amount of injection molding material is controlled according to actual conditions. After the injection molding is completed, the injection molding material needs to be cooled and solidified. After cooling and solidification, the first motor 13 is started again to drive the electric push rod 14 and the connecting block 15 to rise. After rising to the appropriate position, the clamping block 19 is pushed open to remove the plastic part for use. Through the above structure, when the plastic part is injection molded, the electric push rod 14 is driven by the first motor 13 to adjust the lifting and lowering of the shoe mold 16 so that people can use it. The shoe mold 16 is convenient to use, and a plurality of injection channels 18 are provided inside the shoe mold 16, which distributes the injection material to the sole mold 110 more evenly during injection, thereby reducing defects in the plastic parts caused by uneven flow of the injection material, thereby reducing the quality of the plastic parts and improving production efficiency. The plastic parts need to be injected after the clamping block 19 is closed. During the injection molding of the plastic parts, the clamping block 19 is prone to loosening, which in turn causes the sole mold 110 to become loose or even incorrectly positioned, which will affect the injection molding of the plastic parts. In order to reduce this situation, first hold the first handle 23 and push it toward the shoe mold 16. After pushing the first handle 23, the first handle 23 pushes the first splint 2, and at the same time, the first splint 2 pushes the clamping block 19 until the clamping block 19 contacts. After completing the fixation of the sole mold 110, the second handle 25 is then rotated toward the first plywood 2 or the second plywood 21 until the block 24 contacts the first plywood 2 or the second plywood 21, and the sole mold 110 is further fixed. When the cooled plastic part needs to be removed, the second handle 25 is rotated in the opposite direction to make the block 24 away from the first plywood 2 or the second plywood 21. Then the sole mold 110 becomes loose, and the first handle 23 can be easily pushed by the hinge shaft 22 when pushing the first handle 23. Through the above structure, it is convenient to further fix the clamping block 19 by pushing the first plywood 2 and the second plywood 21 when the sole mold 110 is in use, thereby reducing the situation where loosening occurs during injection molding of the plastic part and causes injection molding failure.At the same time, it reduces the loss of injection molding material. After the injection molding is completed, the second motor 32 can be started to reduce the cooling time. After the second motor 32 is started, it drives the rotating shaft 33 to rotate and then drives the connecting column 34 to rotate. After the connecting column 34 rotates, it drives the blades 35 to move to dissipate heat for injection molding, which can shorten the cooling time of the plastic part, thereby improving production efficiency. Through the above structure, the time for plastic part molding is reduced by dissipating heat from the plastic part, thereby improving production efficiency. When the shoe mold 16 is placed inside the connecting block 15, the shoe mold 16 may slip out of the inside of the connecting block 15, resulting in the inability to align the shoe mold 16 with the sole mold 110 and thus the inability to injection mold the plastic part. At this time, the threaded rod 41 is slid and adjusted inside the groove 4, adjusted to the appropriate position, and then the adjusting nut 42 is rotated to fix the threaded rod 41 inside the groove 4 to fix it. Through the above structure, it is easy to adjust the position of the shoe mold 16 to make the plastic part injection molding more accurate. When using the device in different areas, different heights of the areas may be encountered, which makes it inconvenient to use the device. When encountering a higher area, the button 52 can be pressed, and the button 52 squeezes the spring 51. The button 52 will be retracted inside the lifting rod 5, and then the device can be pressed down to descend. At the same time, when encountering a lower area, the button 52 can be pressed, and the button 52 squeezes the spring 51. The button 52 will be retracted inside the lifting rod 5, and then the device can be lifted to ascend. The above structure is conducive to adjusting the lifting of the device when encountering different areas with different heights. When injecting the sole, the plastic part to be injected can be slid into the interior of the fixed block 6 through the slide 61, so that the plastic part to be injected can be injected. At the same time, the plastic part can be easily taken out for injection through the slide 61. The above structure makes it easy to store and store the plastic part to be injected. When placing the device, the anti-slip pad 7 can be used to play an anti-slip role, thereby reducing the slipping phenomenon when using the device, thereby reducing the damage to the device. The above structure effectively avoids the situation where the device slips during operation and causes damage to it.
