Description

Technical Field

[0001] This utility model relates to the field of molds, specifically a rapid demolding structure for injection-molded shoe soles based on multi-channel flow channels. Background Technology

[0002] The rapid demolding structure for injection-molded shoe soles based on multi-channel flow channels is an optimized solution for shoe sole injection mold design. It aims to shorten the injection cycle, reduce defects, and achieve efficient demolding through special flow channel and venting groove design.

[0003] When the multi-channel flow channel is complex, the stress on each area is uneven during demolding. Existing technologies make it difficult to loosen the plastic part as a whole, which increases the risk of sole deformation or ejector pin breakage due to local stress concentration. During use, existing technologies make it difficult to eject the injection molded sole in sections. After long-term operation of the mold, condensation or mold release agent residue will affect demolding. Existing technologies also make it difficult to remove moisture and heat from the mold surface, maintain a dry working environment, and achieve rapid demolding.

[0024] The quick demolding mechanism 2 includes a mounting plate 21. The mounting plate 21 is fixedly connected to the right end of the multi-channel mold body 1. A servo motor 22 is fixedly connected to the lower right front end of the mounting plate 21. The mounting plate 21 facilitates the installation and fixing of the servo motor 22.

[0025] The back output shaft of the servo motor 22 is fixedly connected to a swing block 23. The left end of the swing block 23 is in contact with the right end of the sliding rod 24. A spring 25 is sleeved on the outer wall of the sliding rod 24. A nozzle 26 is fixedly connected to the left end of the sliding rod 24. The nozzle 26 is connected to an external cooling gas delivery box.

[0026] The top of the multi-channel mold body 1 is slidably connected to an ejector pin 27. The outer wall of the ejector pin 27 is slidably connected to the top of the mounting rod 28. Six sets of electromagnetic blocks 29 are fixedly connected inside the mounting rod 28. The electromagnetic blocks 29 facilitate the movement of the ejector pin 27.

[0027] The sliding rod 24 passes through the mounting plate 21 and is slidably connected to its interior. The spring 25 is fixedly connected to the mounting plate 21. The electromagnetic block 29 is electrically connected to the external current output device. The electromagnetic block 29 is magnetically attracted to the ejector pin 27.

[0028] The striking mechanism 4 includes a mounting shell 41. The front end of the fixing rod 3 is fixedly connected to the mounting shell 41. The right end of the mounting shell 41 is fixedly connected to the motor 42. The output shaft of the left end of the motor 42 is fixedly connected to the gear 43, so that the motor 42 can drive the gear 43 to rotate.

[0029] Gear 43 engages with convex rod plate 44. A rotating rod 45 is rotatably connected to the lower right end of convex rod plate 44. A mounting block 46 is rotatably connected to the outer wall of rotating rod 45. Rotating rod 45 facilitates the movement of mounting block 46.

[0030] The bottom of the mounting block 46 is fixedly connected to the striking block 47.

The left end of the protruding rod plate 44 is slidably connected to the left end inside the mounting shell 41.

[0031] The working principle of the above-mentioned rapid demolding structure for injection-molded shoe soles based on multi-channel flow is as follows:

[0032] First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation.

[0033] Secondly, when the multi-channel mold body 1 is in use, the molten plastic enters the multi-channel through the main gate, and after being diverted, it quickly fills the shoe sole cavity. Then, the shrinkage volume is supplemented by the channel, and then it is cooled by the external cooling equipment. Then, the multi-channel mold body 1 is opened. Then, the slope and surface treatment of the channel make the waste material in the flow channel automatically loosen. With the help of the quick demolding mechanism 2, the shoe sole and the flow channel are demolded synchronously and quickly.

[0034] Third, when the multi-channel mold body 1 is opened, the nozzle 26 is connected to the external cooling gas delivery box, and then the motor 42 is started. The motor 42 drives the swing block 23 to swing left and right. The swing block 23 drives the sliding rod 24 to move to the left. During the leftward movement, the sliding rod 24 squeezes the spring 25. When the swing block 23 swings to the right, the sliding rod 24 moves to the right under the influence of the spring 25's restoring force. The left and right movement of the sliding rod 24 drives the nozzle 26 to move left and right. The left and right movement of the nozzle 26 blows air on the multi-channel mold body 1 when it is opened, removing moisture and heat from the mold surface, maintaining a dry working environment, and achieving rapid demolding. When the injection molded shoe sole needs to be ejected, the external current output device drives the six sets of electromagnetic blocks 29 to work step by step, so that the ejector pin 27 moves upward under the influence of the magnetic adsorption of the electromagnetic blocks 29, so that the ejector pin 27 ejects the injection molded shoe sole in segments.

[0035] Fourth, when it is necessary to strike the multi-channel mold body 1, start the motor 42. The motor 42 drives the gear 43 to rotate. The gear 43 drives the convex plate 44 to move up and down or back and forth. The convex plate 44 drives the mounting block 46 to move up and down through the rotational connection with the rotating rod 45. The mounting block 46 drives the striking block 47 to move up and down. The striking block 47 strikes the multi-channel mold body 1, making the plastic parts loose as a whole, reducing the deformation of the shoe sole or the breakage of the ejector pin caused by local stress concentration.

[0036] This utility model provides an improved quick demolding structure for injection-molded shoe soles based on multi-channel flow channels. A quick demolding mechanism 2 is set up, and the ejector pins 27 eject the injection-molded shoe sole in sections by the magnetic adsorption of the electromagnetic block 29. At the same time, the nozzle 26 blows air to remove moisture and heat from the mold surface, maintaining a dry working environment and achieving quick demolding. A striking mechanism 4 is set up, and the striking block 47 strikes the mold body 1 of the multi-channel flow channels to loosen the plastic parts as a whole, reducing the deformation of the shoe sole or the breakage of the ejector pin caused by local stress concentration.
