Description

Technical Field

[0001] This utility model belongs to the field of constant temperature mold temperature controller technology, specifically relating to a constant temperature mold temperature controller for constant temperature of the mold barrel. Background Technology

[0002] A mold temperature controller consists of a heating and cooling system, a power transmission system, a liquid level control system, and components such as temperature sensors and injection ports. Typically, the pump in the power transmission system drives the hot fluid from a water tank containing a built-in heater and cooler to the mold, and then back from the mold to the mold temperature controller.

[0003] Existing temperature control molds used for barrel temperature control have the following drawbacks: they cannot prevent the water temperature from being too low or too high, thus failing to achieve precise control of the barrel (mold) and ensure the normal temperature range for production, affecting the production stability of the barrel (mold). In addition, the control box cannot be adjusted, affecting operation. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides a constant temperature mold temperature controller for barrel temperature control. This controller precisely controls the barrel temperature, ensuring a normal production temperature range, improving the production stability of the mold, increasing the yield rate, and enhancing product quality and efficiency. The control box angle is adjustable.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a constant temperature mold temperature controller for barrel temperature control, comprising a body, a barrel mold seat disposed at the middle of the upper end of the body, a circulating water pump disposed at the middle of the bottom of the body, a cold water inlet pipe connected to the inlet of the circulating water pump, a return pipe connected to the inlet of the circulating water pump, an inlet pipe connected to the outlet of the circulating water pump, a temperature sensor disposed at the upper end of the inlet pipe near the barrel mold seat, a drain pipe connected to the outlet of the barrel mold seat, an electric three-way proportional valve connected to the lower end of the drain pipe, a cold water outlet pipe connected to the outlet of the electric three-way proportional valve, an adjustment component disposed on the side of the body, and a control box connected to the side of the adjustment component.

[0006] Preferably, a temperature sensor is installed at the end of the return pipe near the circulating water pump.

[0007] Temperature sensor 1, circulating water pump, electric three-way proportional valve, and temperature sensor 2 are all electrically connected to the control box.

[0008] The adjustment assembly includes a rotating seat one, a rotating block, a rotating seat two, a telescopic rod, and a rotating component. The rotating seat one is located in the middle of the back of the control box. The rotating block is rotatably connected to the middle of the rotating seat one via a damping shaft. The rotating seat two is rotatably connected to the side of the rotating block via a damping shaft. A telescopic rod is installed in the middle of the side of the rotating seat two. The other end of the telescopic rod is equipped with a rotating component.

[0009] The telescopic rod includes a sleeve rod, a movable rod, and a fastening bolt. The movable rod is movably connected inside the sleeve rod, and the fastening bolt is threadedly connected to the side of the sleeve rod, with the side of the fastening bolt abutting against the surface of the movable rod.

[0010] The rotating assembly includes a threaded connector, a limiting block, a rotating ball, a ball sleeve, and a damping block. The threaded connector has a limiting block on its side, the limiting block has a ball sleeve threadedly connected to its surface, the ball sleeve has a rotating ball rotatably connected to its center, and the limiting block has a damping block located in the middle of its side.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model introduces cold water into the mold base through a cold water inlet pipe and pumps it via a circulating water pump. The cold water then enters the mold base through the inlet pipe. After absorbing heat, the cold water is discharged through the drain pipe. At this time, the chilled water stably controls the temperature of the mold base to the required temperature. When the temperature of the mold base slowly rises, the temperature sensor detects it, and the control box controls the electric three-way proportional valve to open a certain proportion, releasing a portion of hot water into the return pipe. Meanwhile, the circulating water pump appropriately replenishes a certain amount of cold water, allowing the water temperature to be precisely controlled within the set temperature range. This achieves both preventing the water temperature from being too low and controlling it from being too high, thereby achieving precise mold control, ensuring the normal temperature range for production, improving the production stability of the mold, and thus increasing the yield rate, product quality, and efficiency. 2. This utility model is equipped with an adjustment component. The threaded connector is screwed onto the side of the machine body. Loosening the ball sleeve allows the rotating ball to rotate and adjust the angle. Tightening the ball sleeve, in conjunction with the damping block, fixes the angle adjustment of the rotating ball. The rotating block rotates in rotating seat one and rotating seat two, allowing the control box to be adjusted at multiple angles. Loosening the fastening bolt allows the movable rod to move in the sleeve rod. The movable rod stops when adjusted to a suitable position. Tightening the fastening bolt changes the position of the control box to meet different adjustment needs. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example 1 Please see Figure 1-5 The present invention provides the following technical solution: a constant temperature mold temperature controller for constant temperature of the barrel, comprising a body 1, a barrel mold seat 6 disposed at the middle of the upper end of the body 1, a circulating water pump 10 disposed at the middle of the bottom of the body 1, a cold water inlet pipe 9 connected to the inlet of the circulating water pump 10, a return pipe 12 also connected to the inlet of the circulating water pump 10, an inlet pipe 8 connected to the outlet of the circulating water pump 10, a temperature sensor 7 disposed at the upper end of the inlet pipe 8 near the barrel mold seat 6, a drain pipe 5 connected to the outlet of the barrel mold seat 6, an electric three-way proportional valve 11 connected to the lower end of the drain pipe 5, a cold water outlet pipe 4 connected to the outlet of the electric three-way proportional valve 11, an adjustment component 2 disposed on the side of the body 1, and a control box 3 connected to the side of the adjustment component 2.

[0015] Specifically, a temperature sensor 13 is installed at the end of the return pipe 12 near the circulating water pump 10.

[0016] By adopting the above technical solution, temperature sensor 13 detects the temperature of the return water, which facilitates the adjustment of the opening ratio of the electric three-way proportional valve 11 according to the temperature.

[0017] Specifically, temperature sensor 17, circulating water pump 10, electric three-way proportional valve 11, and temperature sensor 2 13 are all electrically connected to control box 3.

[0018] By adopting the above technical solutions, the stable operation of temperature sensor 17, circulating water pump 10, electric three-way proportional valve 11, and temperature sensor 213 is ensured.

[0019] In this embodiment, cold water enters through the cold water inlet pipe 9 and is pumped by the circulating water pump 10. The cold water then enters the mold base 6 through the inlet pipe 8. After absorbing heat, the cold water is discharged through the drain pipe 5. At this time, the chilled water stably controls the temperature of the mold base 6 to the required temperature. When the temperature of the mold base 6 slowly rises, the temperature sensor 7 detects it. The control box 3 controls the electric three-way proportional valve 11 to open at a certain ratio, releasing a portion of hot water into the return pipe 12. At this time, the circulating water pump 10 appropriately replenishes a certain amount of cold water, so that the water temperature is accurately controlled within the set temperature range. This achieves both preventing the water temperature from being too low and controlling the water temperature from being too high, thereby achieving the purpose of precise mold control, ensuring the normal temperature range of production, improving the production stability of the mold, thereby improving the yield rate, product quality and efficiency. Example 2 The difference between this embodiment and embodiment 1 is that the adjustment component 2 includes a rotating seat 21, a rotating block 22, a rotating seat 23, a telescopic rod 24, and a rotating component 25. The rotating seat 21 is located in the middle of the back of the control box 3. The rotating block 22 is rotatably connected to the middle of the rotating seat 21 via a damping shaft. The rotating seat 23 is rotatably connected to the side of the rotating block 22 via a damping shaft. The telescopic rod 24 is installed in the middle of the side of the rotating seat 23. The rotating component 25 is located at the other end of the telescopic rod 24.

[0020] By adopting the above technical solution, the rotating block 22 rotates in the first rotating seat 21 and the second rotating seat 23, enabling the control box 3 to be adjusted at multiple angles. The telescopic rod 24 changes the position of the control box 3, and the rotating assembly 25 changes the angle of the control box 3, thus meeting different adjustment needs.

[0021] Specifically, the telescopic rod 24 includes a sleeve rod 241, a movable rod 242, and a fastening bolt 243. The movable rod 242 is movably connected inside the sleeve rod 241, and the fastening bolt 243 is threadedly connected to the side of the sleeve rod 241. The side of the fastening bolt 243 abuts against the surface of the movable rod 242.

[0022] By adopting the above technical solution, the fastening bolt 243 is loosened, allowing the movable rod 242 to move within the sleeve rod 241. The movable rod 242 is adjusted to a suitable position and then stopped. The fastening bolt 243 is then tightened, causing the position of the control box 3 to change.

[0023] Specifically, the rotating assembly 25 includes a threaded connector 251, a limiting block 252, a rotating ball 253, a ball sleeve 254, and a damping block 255. The threaded connector 251 has a limiting block 252 on its side, the ball sleeve 254 is threadedly connected to the surface of the limiting block 252, the rotating ball 253 is rotatably connected to the middle of the ball sleeve 254, and the damping block 255 is provided in the middle of the side of the limiting block 252.

[0024] By adopting the above technical solution, the threaded connector 251 is screwed onto the side of the machine body 1. Loosening the ball sleeve 254 allows the rotating ball 253 to rotate for angle adjustment. Tightening the ball sleeve 254, in conjunction with the damping block 255, fixes the angle adjustment of the rotating ball 253, thereby changing the angle of the control box 3.

[0025] In this embodiment, the threaded connector 251 is screwed onto the side of the machine body 1. Loosening the ball sleeve 254 allows the rotating ball 253 to rotate for angle adjustment. Tightening the ball sleeve 254, in conjunction with the damping block 255, fixes the angle adjustment of the rotating ball 253. The rotating block 22 rotates in the rotating seat 1 21 and the rotating seat 23, allowing the control box 3 to be adjusted at multiple angles. Loosening the fastening bolt 243 allows the movable rod 242 to move in the sleeve rod 241. The movable rod 242 stops when adjusted to a suitable position. Tightening the fastening bolt 243 changes the position of the control box 3 to meet different adjustment needs.

[0026] The working principle and usage process of this utility model are as follows: When in use, cold water enters through the cold water inlet pipe 9 and is pumped by the circulating water pump 10. The cold water then flows through the inlet pipe 8 into the mold base 6. After absorbing heat, the cold water is discharged through the drain pipe 5. At this time, the chilled water stably controls the temperature of the mold base 6 to the required temperature. When the temperature of the mold base 6 slowly rises, the temperature sensor 7 detects this, and the control box 3 controls the electric three-way proportional valve 11 to open at a certain ratio, releasing a portion of hot water into the return pipe 12. Meanwhile, the circulating water pump 10 appropriately replenishes a certain amount of cold water, allowing the water temperature to be precisely controlled within the set temperature range. This prevents the water temperature from being too low and controls it from being too high, thus achieving precise mold control. The purpose is to ensure the normal temperature range of production, improve the production stability of the mold, thereby increasing the yield rate and improving the quality and efficiency of the product; the threaded connector 251 is screwed onto the side of the machine body 1. Loosening the ball sleeve 254 allows the rotating ball 253 to rotate for angle adjustment. Tightening the ball sleeve 254, the ball sleeve 254, in conjunction with the damping block 255, fixes the angle adjustment of the rotating ball 253. The rotating block 22 rotates in the rotating seat 1 21 and the rotating seat 23, allowing the control box 3 to be adjusted at multiple angles. Loosening the fastening bolt 243 allows the movable rod 242 to move in the sleeve rod 241. The movable rod 242 stops when adjusted to a suitable position. Tightening the fastening bolt 243 changes the position of the control box 3 to meet different adjustment needs.
