DETAILED DESCRIPTION
[0020] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0021] Example 1, please refer to Figure 1-Figure 4 An injection mold for producing a right ear shell includes a fixed mold frame 1, an injection molding support frame 2 and an injection molding frame 3. The injection molding support frame 2 is installed in front of the fixed mold frame 1, and the injection molding frame 3 is installed on the front wall of the injection molding support frame 2. A first load-bearing frame 4 is installed on the lower wall of the fixed mold frame 1, and a second load-bearing frame 5 is installed on the lower wall of the injection molding support frame 2. A guide structure is installed on the side wall of the fixed mold frame 1, and a protective structure is installed on the outer wall of the guide structure. The inner wall surfaces of the first load-bearing frame 4 and the second load-bearing frame 5 are installed with a cooling structure.
[0022] See also Figure 2 The guide structure includes: eight guide threaded rods 6, eight return springs 7 and two guide plates 8; the eight guide threaded rods 6 are respectively installed on the side wall surfaces of the fixed mold frame 1, the eight return springs 7 are respectively sleeved on the outer wall surfaces of the eight guide threaded rods 6, and the two guide plates 8 are respectively installed on the side wall surfaces of the fixed mold frame 1.
[0023] See also Figure 3The protective structure includes: two protective plates 9, two heat insulation plates 10 and eight threaded sleeves 11; the two protective plates 9 are respectively mounted on the outer wall surfaces of the eight guide threaded rods 6, the two heat insulation plates 10 are respectively mounted on the outer wall surfaces of the eight guide threaded rods 6 and are connected to the two protective plates 9, and the eight threaded sleeves 11 are respectively mounted on the outer end surfaces of the eight guide threaded rods 6 and are threadedly connected to the eight guide threaded rods 6.
[0024] See also Figure 3 The two insulation boards 10 are made of aerogel. In this embodiment, the ultra-low thermal conductivity of aerogel ensures its excellent insulation effect. The thermal insulation performance is 2-5 times that of traditional thermal insulation materials, and it can be used in environments ranging from -200°C to 650°C. At the same time, the special nanopore structure of aerogel makes it resistant to pressure and tension, and its service life is more than 5 times that of traditional materials.
[0025] See also Figure 3 The eight threaded sleeves 11 are respectively provided with a plurality of anti-skid grooves. In this embodiment, the anti-skid grooves facilitate unscrewing the eight threaded sleeves 11 around the eight threaded sleeves 11 .
[0026] See also Figure 3 The two protection plates 9 and the two heat insulation plates 10 are respectively provided with two guide grooves 18 . In this embodiment, the protection plates 9 and the heat insulation plates 10 can be moved along the guide plates 8 through the two guide grooves 18 .
[0027] In this embodiment, the reset spring 7 is used to reduce the impact force for the operator. If the operator accidentally hits the fixed mold frame 1, the protective plate 9 and the heat insulation plate 10 will protect the operator. The protective plate 9 drives the heat insulation plate 10 to move inward along the guide plate 8 and the first load-bearing frame 4, and the reset spring 7 contracts along the guide threaded rod 6 to reduce the impact force. The aerogel heat insulation plate 10 prevents the operator from being scalded by the fixed mold frame 1.
[0028] Specifically, when the operator is collecting the right ear shell, if he accidentally hits the fixed mold frame 1, the protective plate 9 and the heat insulation plate 10 will protect the operator, and the protective plate 9 drives the heat insulation plate 10 to move inward along the guide plate 8 and the first load-bearing frame 4, and the reset spring 7 contracts along the guide threaded rod 6 to reduce the impact force and prevent the operator from being injured. When the operator breaks away from the heat insulation plate 10, the reset spring 7 expands along the guide threaded rod 6, driving the protective plate 9 and the heat insulation plate 10 to reset along the guide plate 8 and the first load-bearing frame 4 respectively, and press on the threaded sleeve 11. When replacing the protective plate 9 and the heat insulation plate 10, just unscrew the eight threaded sleeves 11 around them respectively.
[0029] Example 2, please refer to Figure 4The cooling structure includes: a cooling load-bearing frame 12, a water tank 13, a side wall liquid level detector 14, a lower wall liquid level detector 15, a water inlet pipe 16 and a drain pipe 17; the cooling load-bearing frame 12 is installed on the inner wall surfaces of the first load-bearing frame 4 and the second load-bearing frame 5, the water tank 13 is installed on the lower wall surface of the cooling load-bearing frame 12, the side wall liquid level detector 14 is installed on the side wall surface inside the water tank 13, the lower wall liquid level detector 15 is installed on the lower wall surface inside the water tank 13, the water inlet pipe 16 is installed on the side wall surface of the water tank 13, and the drain pipe 17 is installed on the lower wall surface of the water tank 13.
[0030] In this embodiment, the molded right ear shell will fall into the water tank 13 for cooling after demolding. The water in the water tank 13 will gradually evaporate with high temperature. When the lower wall liquid level detector 15 cannot detect water, the water inlet pipe 16 is opened to let water into the water tank 13. When the side wall liquid level detector 14 is detected, the water inlet pipe 16 is closed.
[0031] Specifically, the formed right ear shell will fall into the water tank 13 for cooling after demolding, and the water in the water tank 13 will gradually evaporate with high temperature. When the lower wall liquid level detector 15 can't detect water, the water inlet pipe 16 is opened to let water into the water tank 13. When the side wall liquid level detector 14 is detected, the water inlet pipe 16 is closed. After the work is completed, the operator turns off the main power of the side wall liquid level detector 14 and the lower wall liquid level detector 15, and then opens the drain pipe 17 to completely drain the water in the water tank 13. The lower wall liquid level detector 15 is at a certain distance from the lower wall of the water tank 13, so that the water inside the water tank 13 forms a safe water level from the bottom of the water tank 13, ensuring that the right ear shell can enter the water for cooling after demolding.
[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
