Description

Technical Field

[0001] This utility model relates to the field of shoe sole injection technology, specifically a shoe sole injection mold. Background Technology

[0002] Injection molding is a process that involves injecting liquid rubber into a mold to form the sole. It is mainly used to make rubber shoe soles. Its core feature is that natural or synthetic rubber is injected into a mold and then vulcanized, resulting in properties such as wear resistance, shock absorption, and slip resistance.

[0003] A search revealed Chinese Patent CN218803671U, which discloses an injection mold for producing hiking shoe soles. The mold includes a lower mold body and an upper mold body, both with a guiding mechanism comprising a threaded rod, a rotating disk, a guide plate, and a guide block. The lower mold body has a material-grabbing mechanism comprising a push plate, a spring, a push rod, a high-temperature resistant sealing plug, and a limiting block. This invention, through the rotation of the threaded rod and the threaded connection, can drive the upper mold body to slide stably. Furthermore, the guide plate and guide block effectively guide the upper mold body, ensuring effective mold closing between the upper and lower mold bodies and avoiding the misalignment problem during mold closing in existing technologies. However, the following shortcomings exist in its application.

[0004] When moving the upper mold body, it is necessary to rotate the threaded rod to move the upper mold, which is inconvenient to use. In addition, with long-term use, the friction between the threaded rod and the threaded hole can easily cause stripping. Therefore, a shoe sole injection mold is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a shoe sole injection mold to solve the problem mentioned in the background art, which is that when moving the upper mold body, it is necessary to rotate the threaded rod to drive the upper mold to move, which leads to inconvenience in use. At the same time, with long-term use, the friction between the threaded rod and the threaded hole can easily cause stripping.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shoe sole injection mold, comprising a lower mold, with support columns fixedly arranged at the four corners of the top of the lower mold, an upper mold slidably arranged between the support columns, an anti-detachment structure provided at the top of the support columns, a pulling structure provided at the top of the upper mold, two connecting columns fixedly arranged on both sides of the lower mold, U-shaped support plates provided on both sides of the lower mold and connected to the connecting columns, a buckle fixedly arranged at the top of the U-shaped support plate and fastening the buckle to both sides of the upper mold, a limiting structure fixedly arranged at the top of the upper mold, a pushing structure provided at the top of the lower mold, and a support part provided at the bottom of the lower mold.

[0007] Preferably, the anti-detachment structure includes a baffle plate, which is installed on the top of the support column. A threaded rod is fixedly provided at the bottom of the baffle plate and is threadedly connected to the top of the support column. An auxiliary structure is provided at the top of the baffle plate.

[0008] Preferably, the auxiliary structure includes a fixing plate, which is fixedly installed on the top of the baffle.

[0009] Preferably, the pulling structure includes a first grip, which is fixedly mounted on the top of the upper mold.

[0010] Preferably, the limiting structure includes multiple side plates, which are fixedly installed on the top of the upper mold. Each of the multiple side plates has an elastic steel plate fixedly installed inside. A pressure roller is provided between two side plates at the same level. Sliding rods are fixedly installed on both sides of the pressure roller and are slidably installed inside the side plate. The pressure roller is fastened to the top of the fastening block.

[0011] Preferably, the pushing structure includes a push plate, which is slidably mounted on the outside of the lower mold. Handle structures are provided on both sides of the push plate, and a fixing rod is fixedly mounted on the top of the push plate. A sealing plate is fixedly mounted on the top of the fixing rod and is slidably mounted inside the lower mold.

[0012] Preferably, the grip structure includes two second grips, which are respectively fixedly installed on both sides of the push plate.

[0013] Preferably, the support portion includes multiple support legs, which are respectively fixedly installed at the four corners of the bottom of the lower mold.

[0014] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0015] This utility model, by setting up a U-shaped support plate, a buckle block, a side plate, and an elastic steel plate, allows for the use of an injection mold for producing hiking shoe soles. The injection liquid can be poured into the lower mold. After injection, a pulling structure moves the upper mold upwards, and the U-shaped support plate is rotated to position itself at the bottom of the upper mold. Simultaneously, the buckle block at the top of the U-shaped support plate engages with the upper mold, thus limiting its position. A push plate is then pushed using a second handle to eject the hiking shoe sole from the lower mold, facilitating the removal of the injected sole and making it convenient to use.
