Description

Technical Field

[0001] This utility model relates to the field of power pipe technology, specifically a temperature control mechanism for an MPP power pipe forming mold. Background Technology

[0002] In the molding process of MPP (modified polypropylene) power pipes, temperature plays a crucial role in the quality, performance, and molding efficiency of the pipe. Appropriate temperature control ensures uniform melting and flow of the MPP material, resulting in pipes with excellent appearance quality, dimensional accuracy, and physical properties. The temperature control mechanism of the MPP power pipe molding die is designed to precisely regulate the die temperature to meet the temperature requirements of different stages of pipe molding.

[0003] The existing temperature control mechanism of the MPP power pipe forming mold only heats the injection mold during the temperature control process. This makes it difficult to cool and demold the injection mold during the injection molding process. The equipment cannot maintain the mold at a normal temperature, resulting in limitations in the temperature control of the equipment. At the same time, the mold cannot adjust the length of the pipe according to the user's requirements when injecting the pipe, which reduces the scope of use of the equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a temperature control mechanism for an MPP power pipe molding die, which has the advantages of efficient temperature control during injection molding and adjustable mold injection, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a temperature control mechanism for an MPP power pipe forming mold, comprising a liquid tank, a controller fixedly installed in the liquid tank, a cooling pipe fixedly installed on the inner wall of the liquid tank, a cooling pump fixedly installed on the cooling pipe, a condenser fixedly installed on the cooling pipe, a heat sink rotatably connected to the condenser, a long rod fixedly installed on the inner wall of the condenser, a motor fixedly installed on the long rod, a cooling fan fixedly mounted on the power output shaft of the motor, a support plate fixedly installed on the top of the liquid tank, a lifting rod fixedly installed on the top of the support plate, an upper mold fixedly mounted on the output end of the lifting rod, a temperature sensor fixedly installed on the top of the upper mold, a heating pipe fixedly installed on the inner wall of the upper mold, a support rod fixedly installed on the support plate, a hydraulic rod fixedly installed on the support rod, and a sealing plate fixedly installed on the output end of the hydraulic rod.

[0006] As a preferred technical solution of this utility model: the controller is electrically connected to the lifting rod, and the two sides of the upper mold are slidably connected to the support plate.

[0007] As a preferred technical solution of this utility model: the controller and the hydraulic rod are electrically connected, and the outer wall of the sealing plate is slidably connected to the lower mold and the upper mold.

[0008] As a preferred embodiment of this utility model, the number of hydraulic rods is two, and the two hydraulic rods are respectively located on one side of the outer wall of the sealing plate.

[0009] As a preferred technical solution of this utility model: the controller is electrically connected to the temperature sensor and the heating tube, and the number of heating tubes is several, and the several heating tubes are evenly distributed on the inner walls of the upper mold and the lower mold.

[0010] As a preferred technical solution of this utility model: the controller is electrically connected to the cooling pump and the motor, and the liquid tank is filled with coolant.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The temperature control mechanism of this MPP power pipe molding die uses a controller to heat the upper and lower molds with heating pipes and a cooling pipe to control their temperatures. This ensures that the molten material is placed on the top outer wall of the lower mold for efficient injection molding. The controller also uses a cooling pump to transport coolant from the liquid tank to the inner wall of the condenser through cooling pipes, allowing the liquid to circulate and cool. This coolant carries away the heat generated during injection molding in the lower mold, thus lowering the temperature. The motor drives the cooling fan to rotate, generating negative pressure. This allows the heat generated by the coolant on the inner wall of the condenser to be efficiently dissipated through heat sinks, improving injection molding efficiency.

[0013] 2. The temperature control mechanism of this MPP power pipe forming mold, by placing the molten material on the top outer wall of the lower mold, uses an external force to control the controller, causing the output end of the lifting rod to push the upper mold, so that the upper mold continues to be limited on the inner wall of the support plate, avoiding deviation during the injection molding of the pipe body. By controlling the controller, the output end of the hydraulic rod pushes the sealing plate, so that the sealing plate adjusts the injection space of the lower mold and the upper mold. The molten material placed on the top outer wall of the lower mold and the upper mold is pushed by the external force of the sealing plate, improving the applicability of the equipment.

[0022] In the above structure, by installing the support plate 8, the weight of the lifting rod 9 is supported by the support plate 8, which increases the stability of the upper mold 7 when it moves up and down on the top of the support plate 8.

[0023] In a preferred embodiment: the controller 2 is electrically connected to the lifting rod 9, and the two sides of the upper mold 7 are slidably connected to the outer wall of the support plate 8;

[0024] In the above structure, the outer walls of the upper mold 7 on both sides are slidably connected to the outer wall of the support plate 8. The controller 2 is operated by external force, so that the output end of the lifting rod 9 pushes the upper mold 7, so that the upper mold 7 continues to be limited on the inner wall of the support plate 8, thus avoiding deviation during the injection molding of the tube.

[0025] In a preferred embodiment: the controller 2 is electrically connected to the hydraulic rod 4, and the outer wall of the sealing plate 5 is slidably connected to the lower mold 6 and the upper mold 7;

[0026] In the above structure, by controlling the controller 2, the output end of the hydraulic rod 4 pushes the sealing plate 5, so that the sealing plate 5 can adjust the injection space of the lower mold 6 and the upper mold 7. The molten material placed on the top outer wall of the lower mold 6 and the upper mold 7 is pushed by the external force of the sealing plate 5, thereby improving the applicability of the equipment.

[0027] In a preferred embodiment: there are two hydraulic rods 4, and the two hydraulic rods 4 are respectively located on one side of the outer wall of the sealing plate 5;

[0028] In the above structure, two hydraulic rods 4 are located on one side of the outer wall of the sealing plate 5, so that the sealing plate 5 is pushed by the outer wall of the two hydraulic rods 4, which makes the space between the upper mold 7 and the lower mold 6 adjustable, thereby improving the stability of the equipment for injection molding of tubes of different sizes according to personnel requirements.

[0029] In a preferred embodiment: the controller 2 is electrically connected to the temperature sensor 18 and the heating tube 17, and there are several heating tubes 17, which are evenly distributed on the inner walls of the upper mold 7 and the lower mold 6.

[0031] In a preferred embodiment: the controller 2 is electrically connected to the cooling pump 11 and the motor 15, and the liquid tank 1 is filled with coolant;

[0032] In the above structure, by controlling the controller 2, the coolant in the liquid tank 1 is transported to the inner wall of the condenser 12 through the cooling pipe 10 by the cooling pump 11, so that the liquid can be circulated and cooled. The heat generated by the injection of the lower mold 6 is carried away by the coolant, thereby achieving cooling. The motor 15 drives the cooling fan 14 to rotate, generating negative pressure, and the heat generated by the coolant on the inner wall of the condenser 12 is efficiently dissipated through the heat sink 13, thereby improving the injection efficiency.

[0033] Working principle: By placing the molten material on the top outer wall of the lower mold 6, the external force of the controller 2 causes the output end of the lifting rod 9 to push the upper mold 7, thus limiting the upper mold 7 within the inner wall of the support plate 8 and preventing deviations during tube injection molding. The controller 2 also uses the output end of the hydraulic rod 4 to push the sealing plate 5, adjusting the injection space of the lower mold 6 and upper mold 7. The molten material placed on the top outer wall of the lower mold 6 and upper mold 7 is pushed by the external force of the sealing plate 5, improving the equipment's applicability. The controller 2 also uses the heating tube 17 to heat the upper mold 7 and lower mold. Heating is performed at 6. The temperature of the upper mold 7 and lower mold 6 is controlled by the cooling pipe 10, so that the molten material is placed on the top outer wall of the lower mold 6 to achieve efficient injection molding. By controlling the controller 2, the coolant in the liquid tank 1 is transported to the inner wall of the condenser 12 through the cooling pipe 10, so that the liquid is circulated and cooled. The heat generated by the injection of the lower mold 6 is carried away by the coolant, thereby achieving cooling. The motor 15 drives the cooling fan 14 to rotate, generating negative pressure, and the heat generated by the coolant on the inner wall of the condenser 12 is dissipated through the heat sink 13 to achieve efficient heat dissipation and improve injection molding efficiency.
