Description

Technical Field

[0001] The utility model relates to the field of cooling equipment, in particular to cooling equipment for injection molding products. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automated operation, a wide variety of colors, shapes from simple to complex, sizes from large to small, and precise product size. The product is easy to update and can be made into parts with complex shapes. Injection molding is suitable for mass production and molding processing fields such as products with complex shapes. At a certain temperature, the completely molten plastic material is stirred by a screw, injected into the mold cavity with high pressure, and cooled and solidified to obtain a molded product. This method is suitable for mass production of parts with complex shapes and is one of the important processing methods.

[0003] During injection molding, the temperature of the material is very high, and the mold needs to be cooled to allow the material in the mold to cool quickly and form. The existing cooling equipment directly uses tap water to cool the mold. However, since tap water easily forms scale inside the cooling equipment after absorbing heat, the existing cooling equipment lacks scale cleaning equipment, which causes scale to affect the thermal conductivity of the cooling equipment and the heat absorption and cooling effect of the cooling equipment on the mold. Therefore, in view of the above situation, it is urgent to develop an injection molding product cooling equipment that is easy to clean scale to ensure the heat absorption and cooling performance of the cooling equipment on the mold, so as to overcome the shortcomings in current practical applications and meet current needs.

The mold body 1 A scale cleaning mechanism 4 extending into the two heat-absorbing water-flowing shells 2 is installed. When in use, high-temperature materials are added into the mold body 1 for injection molding, and then tap water is transported to the water flow refrigeration mechanism 3, and the tap water is cooled by the water flow refrigeration mechanism 3. The cold water then flows into the two heat-absorbing water-flowing shells 2, and the mold body 1 is heat-absorbed and cooled by the heat-absorbing water-flowing shells 2, thereby allowing the material in the mold body 1 to be quickly cooled. After a period of use, the scale attached to the inner wall of the heat-absorbing water-flowing shell 2 is cleaned off by the scale cleaning mechanism 4 to prevent the scale from affecting the heat absorption performance of the heat-absorbing water-flowing shell 2.

[0021] The water flow refrigeration mechanism 3 includes: a spiral tube 301, a semiconductor refrigeration sheet 302, a heat dissipation fin 303 and a shunt pipe 304. The right end of the spiral tube 301 is connected to the external tap water through a pipeline. A plurality of semiconductor refrigeration sheets 302 are installed on the outer side of the spiral tube 301. Each semiconductor refrigeration sheet 302 is installed with a heat dissipation fin 303. The heat at the hot end of the semiconductor refrigeration sheet 302 is dissipated through the heat dissipation fin 303 to ensure the semiconductor refrigeration sheet 302 is kept cool. In order to improve the cooling performance, a shunt pipe 304 is connected to the left side of the spiral tube 301, and the shunt pipe 304 is connected to two heat-absorbing water shells 2.

A threaded sleeve 404 is installed on each threaded rod 401. Each threaded sleeve 404 is fixed to a scraper 405. The scraper 405 fits the inner wall of the heat-absorbing water flow shell 2. Since the scraper 405 fits the inner wall of the heat-absorbing water flow shell 2, it cannot rotate, and the threaded sleeve 404 fixed to the scraper 405 cannot rotate and can only move in a straight line. A driving mechanism for driving the two threaded rods 401 to rotate is installed on the mold body 1. Structure 406, the driving mechanism 406 includes: a driving motor 4061, a first gear 4062 and a second gear 4063, the driving motor 4061 is fixed to the outside of the mold body 1, and a heat insulation plate is arranged between the driving motor 4061 and the mold body 1 to prevent the heat on the mold body 1 from being transferred to the driving motor 4061, and the first gear 4062 is installed on the output shaft of the driving motor 4061, and the second gear 4063 that rotates with the first gear 4062 is installed on one side of the first gear 4062, and the second gear 4063 is installed on the threaded rod 401. When in use, the first gear 4062 and the second gear 4063 are driven to rotate by the driving motor 4061, and the threaded rod 401 is driven to rotate by the second gear 4063. The threaded sleeve 404 and the scraper 405 are driven to move by the rotation of the threaded rod 401, and the scale attached to the inner wall of the heat-absorbing water flow shell 2 is scraped off by the scraper 405.
