AI Technical Summary
Traditional injection foaming molds cannot be moved to the next station immediately after injection molding, resulting in reduced processing efficiency.
A foaming mold installation structure was designed, including an upper mold, a lower mold, and a locking mechanism. Through the cooperation of the locking cover plate and the rotating ear plate, the upper and lower molds are tightly engaged and quickly separated by the elastic rotating shaft. Combined with the positioning insert plate and the limiting snap-fit of the insertion hole, the mold can be quickly detached when gripped by the robot arm.
This allows the mold to be quickly moved to the next workstation after injection molding, improving processing efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of foaming molds, specifically a foaming mold installation structure. Background Technology
[0002] Supercritical foaming is a physical foaming technology that uses supercritical fluids (such as carbon dioxide or nitrogen) as foaming agents. The basic principle of supercritical foaming is to mix supercritical fluids with polymer melts, allowing the fluid to fully dissolve in the polymer. Subsequently, by rapidly depressurizing, the fluid quickly vaporizes and expands, forming a large number of microporous structures. Supercritical foaming has advantages such as environmental friendliness, high efficiency, thermal stability, economy, and controllability. Therefore, it is widely used in industries such as footwear, automobiles, packaging, and textiles. Due to its environmental friendliness, high efficiency, and strong controllability, supercritical foaming technology is gradually replacing traditional foaming technologies and becoming an important development direction in the field of materials processing. In the production of shoe sole foaming, injection molding is often used. Multiple molds are placed on a turntable for cyclic processing. After molding, the upper mold is removed by a robotic arm, and then the molded insole is taken out.
[0003] However, because traditional injection molding uses the injection head to apply pressure to stabilize the upper and lower molds during the pressing process, the injection unit cannot immediately move to the next workstation after injection molding, resulting in reduced processing efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figure 1-5 As shown, this embodiment provides a foaming mold mounting structure, including a foaming mold body 1. The foaming mold body 1 includes an upper mold 2 and a lower mold 3. A locking mechanism 9 is installed on the side surface of the upper mold 2. Clamping protrusions 8 are installed on both sides of the locking mechanism 9 on the side surface of the upper mold 2. A positioning plate 10 is provided on the side surface of the lower mold 3 corresponding to the position of the locking mechanism 9. A lower locking tooth 1001 is provided on the outer wall of the positioning plate 10. A guide rod 1002 is installed on the side of the positioning plate 10 away from the lower locking tooth 1001. 9 includes: a rotating ear plate 901 and a locking cover plate 902. The locking cover plate 902 is an L-shaped component. An elastic rotating shaft is installed between the locking cover plate 902 and the rotating ear plate 901. The inner side wall of the locking cover plate 902 is provided with an array of upper locking teeth 903. The locking cover plate 902 is engaged with the lower locking teeth 1001 through the upper locking teeth 903. The inner side of the locking cover plate 902 is provided with a guide insertion hole 203 at the position of the guide rod 1002 on the side surface of the upper mold 2. The positioning plate 10 is limited and engaged with the guide insertion hole 203 through the guide rod 1002.
[0024] like Figure 2-3As shown, in this embodiment, a lower mold 6 is provided on the upper surface of the lower mold 3, and an upper mold 202 is installed directly above the lower surface of the upper mold 2. The lower mold 6 and the upper mold 202 are snapped together. A positioning hole 201 is provided on the outer side of the upper mold 202 on the lower surface of the upper mold 2. A positioning rod 5 is provided on the upper surface of the lower mold 3 at the position corresponding to the positioning hole 201. A fixing pad 4 is installed on the lower surface of the lower mold 3. An installation hole 1003 is provided inside the positioning plate 10. An installation screw 1004 is provided inside the installation hole 1003. The positioning plate 10 is fixedly connected to the lower mold 3 by the installation screw 1004.
[0025] The working principle of this utility model is as follows: During use, after the upper mold 2 is completely covered on the upper surface of the lower mold 3, the upper mold 202 is embedded inside the lower mold 6, and the positioning pin 5 is inserted into the positioning hole 201. The positioning plate 10 is then inserted into the locking mechanism 9, and the guide pin 1002 on the side surface of the positioning plate 10 is inserted into the guide hole 203 on the side surface of the upper mold 2. The lower locking tooth 1001 and the upper locking tooth 903 on the outer side of the positioning plate 10 engage and lock. After the molten material is injected through the injection hole 7, it enters the internal cavity of the upper mold 202 and the lower mold 6 and is formed. Then, the turntable of the installed foaming mold body 1 rotates as a whole. After the robotic arm is positioned below the installation location, it moves to the outside of the upper mold 2 and clamps it. After contacting the L-shaped locking cover 902, the robotic arm controls the locking cover 902 and the rotating ear plate 901 to rotate using the elastic shaft. While continuing to clamp, the robotic arm clamps the outside of the clamping protrusion 8, thus breaking the meshing and locking action between the lower clamping tooth 1001 and the upper clamping tooth 903. Then, the upper mold 2 is pulled away from the top of the lower mold 3, and the molded insole will be embedded inside the lower mold 6. After the molded component is removed, the upper mold 2 can be placed back on the lower mold 3. At the same time, the positioning plate 10 is limited inside the locking mechanism 9, which can ensure that the upper mold 2 and the lower mold 3 are in close contact during foaming.
