[0004] The purpose of this invention is to provide a cavity forming structure that solves the problem that the cooling rate of the cavity in the existing thermoforming mold production process is slow, which greatly reduces the forming efficiency of thermoformed products and is not conducive to the rapid processing and use of large batches of products.

[0005] To achieve the above objectives, this utility model provides a cavity forming structure, including a lower mold, the lower mold having an injection hole that communicates with the forming cavity of the lower mold and is located on the back side of the lower mold, and also including an auxiliary device;

[0006] The lower mold also has a lower water passage hole, which penetrates the lower mold and is located on the lower side of the molding cavity;

[0007] The auxiliary device includes an upper mold, a first quick connector, a second quick connector, and a guide assembly.

The first quick connector is threaded to the lower water passage hole and is located on the front and rear sides of the lower mold. The second quick connector is threaded to the upper water passage hole and is located on the front and rear sides of the upper mold. The guide assembly is located on the side of the lower mold closer to the upper mold.

[0008] The lower mold also has a positioning hole, which is disposed on the upper end surface of the lower mold.

Detailed Implementation

[0019] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0020] Example 1:

[0021] like Figures 1 to 3 As shown, where Figure 1 This is a schematic diagram of the overall structure of the cavity's molding structure. Figure 2 This is a structural schematic diagram of the lower mold 101. Figure 3 This is a schematic diagram of the upper mold 105. This utility model provides a cavity forming structure: including a lower mold 101 and an auxiliary device. The lower mold 101 has an injection hole 102 and a lower water passage hole 104. The auxiliary device includes an upper mold 105, a first quick connector 106, a second quick connector 107, and a guide assembly. The upper mold 105 has an upper water passage hole 108, and the guide assembly includes a guide rod 111 and a slide block 112. The aforementioned solution solves the problem of slow cooling speed of the thermoforming mold cavity in the current thermoforming mold production process, which greatly reduces the forming efficiency of thermoformed products and is not conducive to the rapid processing and use of large-volume products. It is understood that the aforementioned solution can improve the cooling effect of the thermoforming mold, increase the forming efficiency of thermoformed products, and facilitate the rapid processing and use of large-volume products.

[0022] In this embodiment, the lower mold 101 has an injection hole 102, which communicates with the molding cavity 103 of the lower mold 101 and is located on the back side of the lower mold 101. The injection hole 102 communicates with the molding cavity 103 on the lower mold 101, is located on the back side of the lower mold 101, and is externally connected to an infusion tube. When the lower mold 101 is installed, it is mounted on the equipment workbench by positioning pins and bolts.

[0023] The lower mold 101 also has a lower water passage hole 104, which penetrates the lower mold 101 and is located below the molding cavity 103; the lower water passage hole 104 penetrates the lower mold 101 and is located below the molding cavity 103.

[0024] The auxiliary device includes an upper mold 105, a first quick connector 106, a second quick connector 107, and a guide assembly. The upper mold 105 is located above the lower mold 101. The upper mold 105 has an upper water passage hole 108 that penetrates the upper mold 105 and is located on the upper mold 105. The lower water passage hole 104 and the upper water passage hole 108 are threaded holes at both ends. The first quick connector 106 is threadedly connected to the lower water passage hole 104 and is located on the front and rear sides of the lower mold 101. The second quick connector 107 is threadedly connected to the upper water passage hole 108 and is located on the front and rear sides of the upper mold 105. The guide assembly is disposed on the side of the lower mold 101 near the upper mold 105. The upper mold 105 is installed on the power head of the equipment. The upper mold 105 is provided with an upper water passage hole 108 for passing through cooling water. The lower water passage hole 104 and the upper water passage hole 108 are threaded holes on both sides, which facilitates the installation of the first quick connector 106 and the second quick connector 107. The first quick connector 106 and the second quick connector 107 on both sides are respectively connected to the input and output movable water pipes. The movable water pipes can be common rubber air pipes, with the front side being the water inlet and the rear side being the water outlet. The guide component is located on the side of the lower mold 101 near the upper mold 105 for assisting the lower mold 101 in cooperating with the upper mold 105.

[0025] Secondly, the lower mold 101 also has a positioning hole 109, which is disposed on the upper end surface of the lower mold 101. The positioning hole 109 is used to assist the lower mold 101 in cooperating with the upper mold 105.

[0026] Then, the upper mold 105 also has a positioning protrusion 110, which engages with the positioning hole 109 and is located on the side of the upper mold 105 closer to the lower mold 101. When the upper mold 105 and the lower mold 101 are engaged, the positioning protrusion 110 can slide into the positioning hole 109, which helps to improve the stability of the engagement between the lower mold 101 and the upper mold 105.

[0027] Finally, the guide rod 111 is fixedly connected to the lower mold 101 and located on the lower mold 101; the slide block 112 is fixedly connected to the upper mold 105 and slidably connected to the guide rod 111, and is located on the side of the upper mold 105 close to the guide rod 111. The guide rod 111 has a T-shaped cross-section and is installed on the lower mold 101 by positioning pins and bolts. The slide block 112 is installed on the upper mold 105 by positioning pins and bolts. A linear sliding bearing is installed in its through hole to facilitate sliding engagement with the guide rod 111. When the upper mold 105 moves upward to the reset point and stops, the slide block 112 and the guide rod 111 do not separate. The surface of the guide rod 111 is provided with a 0.2mm thick tungsten carbide smooth coating.

[0028] When using this utility model to improve the cooling effect of thermoforming molds, enhance the molding efficiency of thermoformed products, and facilitate the rapid processing of mass-produced products, during processing, the power head of the equipment drives the upper mold 105 downward to cooperate with the lower mold 101, forming a sealed molding cavity 103. During cooperation, the slide block 112 slides vertically on the guide rod 111. Finally, the positioning protrusion 110 slides into the positioning hole 109 to complete the cooperation. Then, the processing liquid is injected through the injection hole 102 to achieve molding processing. At the same time, after the liquid is injected, cooling water can be delivered to the lower water passage hole 104 and the upper water passage hole 108 through the first quick connector 106 and the second quick connector 107, respectively. The cooling water flows from the upper and lower sides of the molding cavity 103, thereby removing heat and achieving rapid cooling of the mold molding cavity 103. This solves the problem that the cooling speed of the thermoforming mold cavity is slow in the current thermoforming mold production process, which greatly reduces the molding efficiency of thermoformed products and is not conducive to the rapid processing of mass-produced products.

[0029] Example 2:

[0030] like Figure 4 As shown, where Figure 4 This is a schematic diagram of the overall structure of the cavity molding structure. Based on the first embodiment, this utility model provides a cavity molding structure. The auxiliary device also includes a filter 201 and an auxiliary quick connector 202.

[0031] The filter 201 is located on one side of the lower mold 101. The auxiliary quick connector 202 is threadedly connected to the filter 201. The auxiliary quick connector 202 is connected to the first quick connector 106 and the second quick connector 107 respectively through a movable delivery pipe, and is located on the front side of the filter 201. The mounting bracket of the filter 201 can be bolted to the equipment frame. The filter 201 has water inlet at the rear and water outlet at the front. Multiple layers of steel wire filter screens are arranged sequentially from the rear to the outside, with the filter screen pore diameter gradually decreasing to achieve multi-stage filtration. The auxiliary quick connector 202 is annularly installed on the front water outlet end of the filter. The auxiliary quick connector 202 is connected to the first quick connector 106 and the second quick connector 107 on the front side respectively through a movable delivery pipe to achieve water supply.

[0032] In this embodiment, by setting the filter 201 and the auxiliary quick connector 202, the cooling water entering the lower water inlet 104 and the upper water inlet 108 can be filtered in advance, so as to avoid excessive impurities in the lower water inlet 104 and the upper water inlet 108 causing blockage after a long time, which would affect the use.
