Description

Technical Field

[0001] This application relates to the field of foamed shoe sole processing, and in particular to a supercritical foamed shoe sole mold. Background Technology

[0002] Rubber foam soles are outsole materials made from natural or synthetic rubber, using closed-cell or open-cell foamed materials. The process involves adding grease, white oil, silica, accelerators, antioxidants, foaming agents, spindle oil, etc., to raw rubber materials, mixing them in an open or closed mixing mill, and then pressing the mixture into raw sheets. These sheets are then placed in a flat vulcanizing mold and vulcanized in a flat vulcanizing machine to become rubber foam sheets, which are then transferred to the shoe sole manufacturing process.

[0003] After the foamed sole is formed, the upper mold moves up and separates from the lower mold. However, because the formed foamed sole is inside the lower mold, its periphery is attached to the inner wall of the lower mold without any gaps, making it inconvenient to remove the formed foamed sole, thus affecting the overall processing efficiency. Utility Model Content

[0004] To address the problem that the molded foamed sole is tightly fitted to the inner wall of the lower mold without any gaps, making it inconvenient to remove the molded foamed sole, this application provides a supercritical foamed sole mold.

A first support seat is installed on the upper part of the first movable component, and a second support seat is installed on the second movable component. Support columns are installed on the first and second support seats. A first lower mold and a second lower mold are respectively connected to the first and second support seats through the support columns. Both the first and second lower molds have half molds, and the two half molds are assembled into an inner mold.

[0007] By adopting the above technical solution, when the rotating rod rotates, it can drive the first moving part and the second moving part to move inward or outward synchronously through the bidirectional threads at both ends. When the first moving part and the second moving part move inward synchronously, they can drive the first lower mold and the second lower mold on the first support base and the second support base to move closer together.

[0008] Preferably, the first lower mold and the second lower mold are arranged opposite to each other, and both the first lower mold and the second lower mold are provided with positioning holes, so that the first lower mold and the second lower mold can be assembled into a complete lower mold.

[0009] By adopting the above technical solution, the first and second lower molds are brought close together, and the two half molds form a complete inner mold. Foaming material is placed in the inner mold and gradually lowered through the upper mold. The positioning pins and positioning holes on the upper mold cooperate, and then the upper mold and the lower mold cooperate to form the foamed shoe sole.

[0010] Preferably, the base has four moving slots, and the lower ends of the first and second moving parts are provided with limiting blocks. The width of the limiting blocks is adapted to the width of the moving slots. The limiting blocks are located inside the moving slots, and rollers are provided on the inner side of the limiting blocks.

[0011] By adopting the above technical solution, the first moving part and the second moving part can drive the first support base and the second support base to move when they move, and the rollers can make the overall movement more stable.

[0012] Preferably, a dual-axis motor is connected to the middle of the rotating rod, the output end of the dual-axis motor is connected to the rotating rod in a transmission connection, and the dual-axis motor is connected to the inner side of the base.

[0013] By adopting the above technical solution, the rotating rod is driven to rotate by a dual-axis motor. When the rotating rod rotates, the first and second moving parts can be driven to move synchronously inward or outward through the bidirectional threads at both ends.

[0014] Preferably, a first connecting shaft is mounted on the first support base, and a second connecting shaft is mounted on the second support base. The first support base is movably connected to a first connecting rod via the first connecting shaft, and the second support base is connected to a second connecting rod via the second connecting shaft.

[0015] By adopting the above technical solution, when the first moving part and the second moving part move outward synchronously, the first connecting rod and the second connecting rod can be driven to move, and the first support base and the second support base can be kept moving synchronously.

[0016] Preferably, the first connecting rod and the second connecting rod are arranged in a cross configuration, and the intersection of the first connecting rod and the second connecting rod is movably connected by a central shaft.

[0017] By adopting the above technical solution, when the first moving part and the second moving part move outward synchronously, the first connecting rod and the second connecting rod can be driven to move around the central axis.

[0018] Preferably, the first support base has a first movable groove, the second support base has a second movable groove, one end of the second connecting rod is equipped with a second limiting post, the second connecting rod is movably connected to the inside of the first movable groove through the second limiting post, and one end of the first connecting rod is equipped with a first limiting post, the first connecting rod is movably connected to the inside of the second movable groove through the first limiting post.

[0019] By adopting the above technical solution, when the first moving part and the second moving part move outward synchronously, the first connecting rod and the second connecting rod can be driven to move around the central axis. The first limiting post and the second limiting post will move inside the first movable groove and the second movable groove, which can keep the first support seat and the second support seat moving synchronously.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. In this application, the upper mold is lowered step by step, the positioning pins and positioning holes on the upper mold cooperate, and then the upper mold and the lower mold cooperate to form the foamed shoe sole. After forming, the first moving part and the second moving part move outward synchronously, which can separate the first lower mold and the second lower mold, and make it easy to remove the formed foamed shoe sole.

[0022] 2. By moving the first and second moving parts outward, this application can drive the first and second connecting rods to move around the central axis. The first and second limiting posts will move inside the first and second movable slots, which can keep the first and second support seats moving synchronously and improve the overall practicality.
