Description

Technical Field

[0001] The invention relates to the technical field of sole processing, in particular to a two-color sole processing mold and a processing technology. Background Art

[0002] In the prior art, there are single-layer soles and double-layer soles. The injection mold for the single-layer sole only has a shoe last mold frame and a sole mold frame, and then the sole is cast and then closed. If a double-layer sole is to be cast, especially for two-color soles or soles of different materials, the sole is cast first, and then the cast sole and the shoe last are cast again to form a double-layer sole. The mold assembly of this structure must have a shoe last mold frame and a sole mold frame, and the sole mold frame must also be equipped with a sole mold cover. After the sole mold cover and the sole mold frame are made into the lower sole, the sole mold frame and the shoe last mold frame are closed to cast the midsole.

[0003] In this regard, China has applied for patent number: CN202211206062.9, which discloses a double-layer sole forming process and a forming mold, comprising the following steps: A. Preparing two different sole raw materials. The double-layer sole forming process of the present invention forms a first-layer sole forming cavity by adjusting the sole mold for the first time, and then adjusts the sole mold for the first time to form a second-layer sole forming cavity. The thickness of the double-layer sole can be adjusted according to demand, and only needs to be operated on the sole mold without adding any parts, which is convenient to operate. The double-layer sole forming mold includes a base, an upper template and two lower templates. When the double-layer sole forming mold of the invention is in use, the thickness of the first layer of the sole is adjusted according to actual needs by raising the sole pattern forming part close to the upper template. The thickness of the double-layer sole can be adjusted only by operating the lifting sole pattern forming part, and the sole thickness can be freely adjusted, which makes the operation more convenient and quick.

[0004] The device is equipped with a micro hydraulic cylinder to drive the sealing plate to move up and down, so that when producing the first layer of soles, the sealing plate is moved to the upper side, so that the material is formed between the upper side of the lower template and the upper template. However, when the sealing plate is moving, it needs to move up and down between the lower templates, so there will be a gap between the sealing plate and the lower template. The setting of the gap will affect the sealing performance of the device. Therefore, when producing the first layer of soles, the material will leak downward along the gap, making it impossible to guarantee the quality of the product and affecting the user experience.

[0005] Therefore, in order to solve the above problems, a two-color sole processing mold and processing technology are proposed. Summary of the Invention

However, when the sealing plate is active, it needs to be raised and lowered between the lower template, so there will be a gap between the sealing plate and the lower template, and the setting of the gap will affect the sealing performance of the device.

[0028] A two-color sole processing technology: S1. Pull the handle 211 to cover the cover 28 on the top surface of the sole mold 1. The material is added to the inside of the mold cavity 29 through the injection port. After the material is formed, pull the handle 211 to open the cover 28 from the top surface of the sole mold 1. The round rod 212 can reserve multiple holes on the top surface of the first layer of the sole; S2. Pull the handshake 36 to cover the shoe last mold 33 on the top surface of the sole mold 1, the gear 37 drives the movable plate 216 to slide, the movable plate 216 drives the slope 218 to push the movable block 25 upward, adjust the position height between the cover plate 28 and the sole mold 1; S3.

The movable plate 216 can drive the block 219 to be pulled out from the inside of the slot 27, which can release the shoe last mold 33. The movable block 25 is fixed inside the guide groove 23, and the slope 218 slides in the movable groove 22. The slope 218 moves to the bottom surface of the movable block 25 and slides along the inclined surface of the bottom of the movable block 25, pushing the movable block 25 upward, so that the movable block 25 moves upward along the guide groove 23. The movable block 25 rises upward and drives the cover plate 28 to rise upward. The position height between the cover plate 28 and the sole mold 1 can be adjusted to reserve space for the installation of the shoe last mold 33 on the top surface of the sole mold 1. Then, pull the handle 211, flip the cover plate 28 again, and cover the top surface of the shoe last mold 33 with the cover plate 28. Before the cover plate 28 contacts the shoe last mold 33, the cover plate 28 will drive the abutment rod 214 to contact the pad 35 first. The pad 35 will react on the abutment rod 214, causing the abutment rod 214 to retract upward into the bottom surface of the cover plate 28. When the abutment rod 214 moves, it will drive the round rod 212 to retract into the inside of the hole groove 210, and the round rod 212 will squeeze the second spring 213, so that the hole groove 210 The bottom end of the groove 210 is left empty, and the material is added to the inside of the mold cavity 29 again through the injection port. The material will contact the top surface of the first layer of the sole and fill the holes on the top surface of the first layer of the sole, which can increase the bonding strength between the first layer of the sole and the second layer of the sole, and the material will form a bulge inside the bottom end of the hole groove 210, which can increase the friction between the sole and the foot. The inner walls of the sole mold 1, the cover plate 28 and the shoe last mold 33 are all fixed structures, which can ensure sealing, effectively avoid material leakage, and ensure the smooth progress of the sole processing work.
