Description

Technical Field

[0001] The utility model belongs to the technical field of injection molds, and in particular relates to a cooling device for a rotating thread insert of an injection mold. Background Art

[0002] The injection mold rotating thread insert cooling device is a special cooling system used in the injection molding process. The main function of this device is to quickly and evenly cool the mold during the injection molding process, thereby improving production efficiency and ensuring product quality.

[0003] In the field of injection molding, the cooling efficiency of the mold is one of the key factors affecting product quality and production efficiency. Traditional cooling systems usually adopt a fixed cooling pipe design. This design is often difficult to achieve uniform and efficient cooling effects when facing large or complex molds. Some parts of the mold may shrink, deform or stress concentrate due to insufficient cooling, which directly affects the quality and output of the final product. In addition, uneven cooling will also extend the production cycle, reduce production efficiency and increase production costs. Therefore, in the prior art, finding a solution that can effectively improve cooling efficiency and uniformity is of great significance to improving the overall performance of injection molding. Utility Model Content

When facing large or complex molds, this design is often difficult to achieve a uniform and efficient cooling effect. Some parts of the mold may cause shrinkage, deformation or stress concentration in the product due to insufficient cooling, which directly affects the quality and output of the final product. In addition, uneven cooling will also extend the production cycle, reduce production efficiency and increase production costs.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cooling device for a rotating threaded insert of an injection mold, comprising a threaded insert, a cooling water pipe, a rotating water pipe joint and a joint connecting pipe, wherein one end of the cooling water pipe is fixedly connected to the threaded insert, and the other end of the cooling water pipe is equipped with a rotating water pipe joint, and the end of the rotating water pipe joint away from the cooling water pipe is fixedly equipped with a joint connecting pipe, and a water inlet pipe joint is fixedly installed on the side surface of the joint connecting pipe.

[0012] Compared with the prior art, the utility model provides a cooling device for a rotating thread insert of an injection mold, which has the following beneficial effects:

[0013] 1. The cooling water inside the utility model flows in from the water inlet pipe joint through a carefully laid out piping system, flows through the rotary joint, the link block, and finally enters the cooling pipe. In this process, the cooling water effectively absorbs the heat in the mold, especially through the cooling holes in the spiral insert, to achieve precise control of the mold surface temperature. This efficient cooling mechanism not only speeds up the cooling of the product, but also ensures the stability of the product size and reduces deformation, thereby significantly improving the quality and output of injection molded products, and effectively avoiding the traditional cooling system that usually adopts a fixed cooling pipe design. This design is often difficult to achieve uniform and efficient cooling effects when facing large or complex molds. Some parts of the mold may shrink, deform or stress concentrate due to insufficient cooling, which directly affects the quality and output of the final product. In addition, uneven cooling will also extend the production cycle, reduce production efficiency, and increase production costs.

[0014] 2. In the present invention, the improvement of cooling efficiency directly affects the efficiency of injection molding production. Since the cooling system can quickly and effectively reduce the mold temperature, the production cycle can be shortened, the number of mold changes is reduced, and the production process is smoother. This efficiency improvement is crucial for injection molding processes with continuous production and high output requirements. It not only speeds up production, but also reduces production costs, improves the company's market competitiveness and economic benefits. In addition, the improvement of production efficiency also means higher output, which is crucial to meeting the market demand for injection molding products;

[0015] 3. The layout of this utility model is concise and easy to access, making maintenance work faster and more efficient. The flow path of cooling water is clear, easy to check and clean, and reduces potential blockage problems. In addition, due to the modular design of the cooling system, it is more convenient to replace parts, reducing maintenance costs and time. Regular maintenance can ensure the stable operation of the cooling system and prevent mold damage and production interruptions caused by insufficient cooling or failure. This design that facilitates maintenance improves overall production efficiency and product quality. BRIEF DESCRIPTION OF THE DRAWINGS
