Description

Technical Field

[0001] This utility model relates to the field of water pipe connector technology, specifically a water pipe connector injection molding mold. Background Technology

[0002] Injection molding mold, or injection mold for short, is a mold made according to the shape and structure of a real object. Its working principle is to inject molten plastic into the mold cavity of the mold by high pressure from the injection molding machine, and obtain the molded product after cooling and solidification.

[0003] Water pipe fittings require injection molding molds during production. Due to the high temperature of the injection-molded products, the fittings tend to stick to the mold after molding and cannot be automatically demolded. Usually, a cooling device needs to be installed on the mold to speed up the molding process and facilitate demolding. However, existing water pipe fitting molds typically use a single water cooling system, which has low cooling efficiency, hinders rapid demolding, and affects processing efficiency. Therefore, further improvements are needed. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0020] Reference Figures 1 to 4 In this embodiment of the utility model, a water pipe connector injection molding mold includes: a device body 1, an electric telescopic rod 2 and a motor 5. An upper mold assembly 3 is provided below the electric telescopic rod 2. A lower mold assembly 4 is provided at one end inside the device body 1. A stirring mechanism 6 is provided above the motor 5. A water cooling mechanism 7 is provided at one end below the lower mold assembly 4. A water tank 8 is fixedly connected to one side end of the device body 1.

[0021] The stirring mechanism 6 includes a main shaft 61 fixedly connected to the output shaft above the motor 5. A first gear 62 is fixedly connected to one side end of the main shaft 61. A second gear 63 is provided at one side end of the first gear 62. A fixing rod 64 is fixedly connected to one upper end of the second gear 63. A stirring paddle 65 is fixedly connected to the side of the fixing rod 64. A fan blade 66 is fixedly connected above the main shaft 61.

[0022] The water cooling mechanism 7 includes an inlet pipe 71 located at one side of the water tank 8, a water pump 72 located at one side of the inlet pipe 71, a water cooling pipe 74 located at one side of the inlet pipe 71, and an outlet pipe 73 located at one side of the water cooling pipe 74.

[0023] The above solution is adopted: the water pump 72 inputs cold water in the water tank 8 into the water cooling pipe 74 through the water inlet pipe 71, thereby cooling the lower mold base 41, and then the cold water re-enters the water tank 8 through the water outlet pipe 73.

[0024] The upper mold assembly 3 includes an upper mold base 31 fixedly connected to the lower output end of the electric telescopic rod 2. An upper mold 32 is fixedly connected to one lower end of the upper mold base 31, and limit rods 33 are symmetrically arranged at both lower ends of the upper mold base 31.

[0025] The lower mold assembly 4 includes a support block 42 fixed to one side of the main body 1, a lower mold base 41 at one side of the support block 42, and a limit hole 43 at the upper end of the lower mold base 41.

[0026] There are four sets of the second gear 63, the fixing rod 64 and the stirring paddle 65, which are arranged around the side of the first gear 62. The second gear 63 is rotatably connected to the inside of the water tank 8.

[0027] The above scheme is adopted: the motor 5 drives the main shaft 61 to rotate, the first gear 62 fixed to the side of the main shaft 61 drives the second gear 63 meshing on the side to rotate, and the rotation of the second gear 63 drives the fixed rod 64 fixed above and the stirring paddle 65 fixed to its side to rotate, thereby stirring the water inside the water tank 8 and cooling the water inside the water tank 8, so as to ensure that the water temperature is always at a temperature that can cool the lower mold base 41. When the main shaft 61 rotates, it also drives the fan blade 66 fixed above to rotate, thereby further cooling the water cooling pipe 74 and the lower mold base 41.

[0028] The working principle of this utility model is as follows: First, cold water is added to the water tank 8. Then, the cold water is pumped into the water cooling pipe 74 through the water inlet pipe 71 by the water pump 72, thereby cooling the lower mold base 41. Then, the cold water re-enters the water tank 8 through the water outlet pipe 73. Then, the motor 5 drives the main shaft 61 to rotate. The first gear 62 fixed to the side of the main shaft 61 drives the second gear 63 meshing on the side to rotate. When the second gear 63 rotates, it drives the fixed rod 64 fixed above and the stirring paddle 65 fixed to its side to rotate, thereby stirring the water inside the water tank 8 and cooling the water inside the water tank 8. This ensures that the water temperature is always at a temperature that can cool the lower mold base 41. When the main shaft 61 rotates, it also drives the fan blade 66 fixed above to rotate, thereby further cooling the water cooling pipe 74 and the lower mold base 41.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
