Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hot forming equipment, in particular to a temperature control device of a hot forming equipment. BACKGROUND

[0002] In the production operation of the hot forming mold, the cooling water tower cools the mold through the circulating water system, which is a key facility to ensure the stability of the mold temperature and the quality of the molded product. The core working logic is: the circulating pump sends the cooled water in the cooling water tower to the cooling flow channel of the hot forming mold, and after the water flow absorbs the heat generated in the hot forming process of the mold, it carries the heat back to the cooling water tower, and after cooling through heat exchange (air and water contact heat dissipation) in the tower, it is sent to the mold again by the circulating pump to form a closed loop circulation, and the mold temperature control is realized by continuously removing heat.

[0003] The existing cooling system has obvious shortcomings in adapting to the dynamic temperature control requirements of the hot forming mold, and the core problem is that the circulating water flow cannot be flexibly adjusted according to the mold cooling requirements. The circulating pump is the power source for water flow delivery, and its power is fixed, which means that the amount of cooling water pumped per unit time is relatively constant, and it cannot adapt to the real-time cooling amplitude requirements of the mold. In hot forming production, the mold temperature will fluctuate dynamically due to the different materials, thicknesses and production rhythms of the molded products. For example, when processing thick-walled plastic parts, the mold generates more heat per unit time, and more cooling water is needed to quickly remove the heat. When processing thin-walled parts, the mold generates less heat, and the amount of cooling water needs to be reduced to avoid the mold temperature being too low to cause product forming defects. The circulating pump with fixed power cannot match this dynamic demand: when the mold needs to be cooled quickly, the constant flow of cooling water cannot efficiently remove excess heat, causing the mold temperature to remain high, prolonging the molding cycle, and possibly causing product defects such as shrinkage, deformation, etc. When the mold needs to maintain a low cooling rate, the excess cooling water will continue to remove heat, causing the mold temperature to be too low, affecting the flow and solidification of the plastic melt, and causing problems such as material shortage at the corners of the product and obvious joint lines. This mismatch between flow and demand directly leads to poor temperature control accuracy and insufficient stability of the hot forming mold, making it difficult to meet the high-quality molding requirements of different specifications of products. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application aims to provide a temperature control device of a hot forming equipment to solve the problems raised in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a temperature control device for a thermoforming equipment, comprising a water collection tank, a spray tower mounted on the upper side of the water collection tank, a water outlet pipe installed on one side of the water collection tank, a tee pipe installed at the end of the water outlet pipe away from the water collection tank, switching valves installed at both ends of the tee pipe away from the water outlet pipe, a circulation pump connected to the end of the switching valve away from the tee pipe via a check valve, a shut-off valve installed at the outlet end of the circulation pump, two shut-off valves connected to the two circulation pumps being connected via a connecting pipe, a water supply pipe connected via a branch pipe, two gate chambers connected via the water supply pipe, each gate chamber having a slotted opening on its opposite side, a gate plate for separating the internal space of the gate chamber being inserted into each of the slotted openings, a linkage component installed between the two gate plates, one gate chamber being connected to the spray tower via a return pipe, and the other gate chamber being connected to the water inlet of the thermoforming mold via a cold water pipe, and a return pipe for connecting the water outlet of the thermoforming mold being installed on one side of the spray tower. Spray towers typically spray hot water from top to bottom to cool it down, often in conjunction with fans to accelerate the cooling process.

[0006] Specifically, the linkage includes a triangular block, which is installed between the two gates. One side of the triangular block is machined with a first inclined surface, and a top block is attached to the first inclined surface. One side of the top block is machined with a second inclined surface, and the first inclined surface and the second inclined surface are in sliding contact. A driving component for driving the top block to move up and down is rotatably installed on the lower surface of the top block.

[0007] Specifically, a connecting rod is installed between the two gates, and a U-shaped frame is fitted on the connecting rod. Both ends of the U-shaped frame are connected to triangular blocks, and the connecting rod is connected to the U-shaped frame by screws.

[0008] Specifically, the driving component includes a screw, which is rotatably mounted on the lower surface of the top block. An L-shaped frame is provided on one side of the top block. A threaded hole is opened on the horizontal part of the L-shaped frame, and the screw is threaded into the threaded hole. A handle rod is inserted into a shaft hole at the lower part of the outer surface of the screw. Two horizontally arranged tubes are installed on the vertical part of the L-shaped frame. A telescopic rod is inserted into the tube. One end of the telescopic rod on the outside of the tube is connected to a triangular block. A compression spring is sleeved on the structure formed by the telescopic rod and the tube. The two ends of the compression spring are in contact with the L-shaped frame and the triangular block, respectively.

[0009] Specifically, a cover is installed on the vertical part of the L-shaped frame away from the tube. Two connecting holes are opened in the area of ​​the vertical part of the L-shaped frame covered by the cover. The connecting holes communicate with the internal space of the cover and the corresponding internal space of the tube. A piston is installed at one end of the telescopic rod inside the tube. The piston is slidably installed inside the tube. A vertical hole is opened on the horizontal part of the L-shaped frame. A vertical tube is installed in the vertical hole. A bent tube is installed at the lower part of the vertical tube. The end of the bent tube away from the vertical tube is connected to the cover. A rubber plug is slidably installed inside the vertical tube. A top rod is installed at the middle of the upper surface of the rubber plug. A support plate is fixedly connected to the upper end of the top rod. An arc plate is installed at the end of the support plate away from the top rod. The arc plate wraps around the screw rod. The arc plate is located on the side of the screw rod away from the vertical part of the L-shaped frame.

[0010] Specifically, a positioning seat is installed at the top of the vertical part of the L-shaped frame. The upper surface of the positioning seat has multiple fixing holes. A reinforcing rib is installed on the lower surface of the positioning seat near the L-shaped frame. The end of the reinforcing rib away from the positioning seat is connected and fixed to the L-shaped frame.

[0011] Specifically, the gate chamber has a rectangular cross-section, and the side of the gate chamber facing the water supply pipe is open. A chamber cover is installed at the open end of the gate chamber, and a pipe joint is installed in a circular opening on one side of the chamber cover. The end of the pipe joint away from the chamber cover is connected to the water supply pipe.

[0012] Specifically, a support frame is provided on the outside of the strip-shaped opening. One end of the support frame is connected and fixed to the gate chamber. A sealing sleeve is glued inside the support frame and the sealing sleeve is wrapped around the gate plate.

[0013] Specifically, a bottom frame is installed at the bottom of the water collection tank, a bracket is installed at the bottom of the bottom frame, and multiple support rods for supporting the spray tower are evenly installed between the water collection tank and the spray tower.

[0014] Specifically, the top of the spray tower is provided with a ventilation opening, and a ring for supporting the fan is provided on the upper side of the ventilation opening, which is concentrically arranged with the ventilation opening.

[0015] The beneficial effects of this invention are: Rotating the screw of the drive unit can drive the top block to move up and down. The second inclined surface of the top block slides into contact with the first inclined surface of the triangular block, pushing the triangular block to move laterally, which in turn drives the two gates to slide in opposite directions synchronously. One gate opens to increase the water flow channel of the cold water pipe, while the other gate closes to decrease the water flow channel of the return pipe, or vice versa. Compared with the crude method of relying solely on the pump body for adjustment, stepless control of the cooling water flow is achieved, improving the temperature control accuracy of the mold.

[0016] When the screw is turned, the screw drives the top block to move up and down, which in turn moves the triangular block laterally. Combined with the rebound force of the compression spring, the triangular block moves laterally stably. The telescopic rod and the tube work together to support the compression spring. After the compression spring is compressed, the fluid medium in the tube enters and exits the casing through the connecting hole under the action of the piston. Since the casing is connected to the vertical cylinder through the bend, the rubber plug moves up and down in the vertical cylinder. As a result, the rubber plug drives the arc plate to move up and down along the screw through the top rod. At this time, the arc plate and other components work together to support the screw, reduce the impact of the rebound force of the compression spring on the screw, and protect the screw.

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-8 This invention provides a technical solution: a temperature control device for a thermoforming equipment, including a water collection tank 100, a bottom frame 103 installed at the bottom of the water collection tank 100, and a bracket 1031 installed at the bottom of the bottom frame 103. The structure formed by the bracket 1031 and the bottom frame 103 supports the water collection tank 100. A spray tower 102 is provided on the upper side of the water collection tank 100, wherein a plurality of support rods 101 for supporting the spray tower 102 are evenly installed between the water collection tank 100 and the spray tower 102, and a side of the spray tower 102 is equipped with... The return water pipe 1022 is used to connect the outlet of the thermoforming mold. The support rod 101 connects the spray tower 102 and the water collection tank 100. The top of the spray tower 102 is provided with a vent. On the upper side of the vent, there is a ring 1021 arranged concentrically with the vent to support the fan. After the cooling water flows into the spray tower 102, the vent at the top of the spray tower 102 and the fan supported by the ring 1021 can accelerate the heat dissipation of the water and ensure that the temperature of the return cooling water drops to a suitable range, thus providing a guarantee for recycling.

[0020] A water outlet pipe 200 is installed on one side of the water collection tank 100. A three-way pipe 201 is installed at the end of the water outlet pipe 200 away from the water collection tank 100. Switching valves 2011 are installed at both ends of the three-way pipe 201 away from the water outlet pipe 200. A circulation pump 202 is connected to the end of the switching valve 2011 away from the three-way pipe 201 through a check valve 2012. A shut-off valve 2021 is installed at the outlet end of the circulation pump 202. The two shut-off valves 2021 connected to the two circulation pumps 202 are connected to each other through a connecting pipe 2022. The connecting pipe 2022 is connected to a water delivery pipe 203 through a branch pipe 204. The check valve 2012 at the inlet of the circulating pump 202 prevents the cooling water from flowing backward, avoiding backflow caused by the shutdown of the circulating pump 202 or pressure fluctuations, and ensuring a stable water supply direction. The shut-off valve 2021 at the outlet of the circulating pump 202 can close another channel when a single pump is running, preventing water diversion and ensuring an effective water supply. The shut-off valve 2021 and the switching valve 2011 work together to avoid flow fluctuations caused by water turbulence, ensuring a stable amount of cooling water flowing to the mold and providing a stable water flow basis for mold temperature control.

[0021] Two gate chambers 300 are installed on the outer surface of the water supply pipe 203. Each gate chamber 300 has a rectangular cross-section and an open side facing the water supply pipe 203. A cover 305 is installed at the open end of each gate chamber 300. A circular opening is formed on one side of the cover 305, and a pipe connector 301 is installed inside this opening. The end of the pipe connector 301 away from the cover 305 is connected to the water supply pipe 203. The structure formed by the pipe connector 301 and the cover 305 enables communication between the gate chambers 300 and the water supply pipe 203. The connection is as follows: Two gate chambers 300 have strip-shaped openings on their opposite sides, and gate plates 400 for separating the internal space of each gate chamber 300 are installed in each of the two strip-shaped openings; a support frame 306 is provided on the outside of the strip-shaped openings, one end of the support frame 306 is connected and fixed to the gate chamber 300, and a sealing sleeve 3061 is glued inside the support frame 306. The sealing sleeve 3061 wraps around the gate plate 400, improving the sealing between the gate plate 400 and the strip-shaped openings and preventing cooling water leakage.

[0022] One gate chamber 300 is connected to the spray tower 102 via a return pipe 302, and the other gate chamber 300 is connected to the inlet of the thermoforming mold via a cold water pipe 303. A triangular block 500 is installed between the two gate plates 400, and a connecting rod 401 is installed between the two gate plates 400. A U-shaped frame 4011 is fitted on the connecting rod 401, and both ends of the U-shaped frame 4011 are connected to the triangular block 500. The connecting rod 401 is connected to the U-shaped frame 4011 via screws 4012, so that the relative positions of the two gate plates 400 and the triangular block 500 remain unchanged.

[0023] A triangular block 500 has a first inclined surface 503 machined on one side, and a top block 501 is attached to the first inclined surface 503. A second inclined surface 5011 is machined on one side of the top block 501, and the first inclined surface 503 and the second inclined surface 5011 are in sliding contact. A screw 502 is rotatably mounted on the lower surface of the top block 501. An L-shaped bracket 304 is provided on one side of the top block 501. A threaded hole is opened in the horizontal part of the L-shaped bracket 304, and the screw 502 is threaded into the threaded hole. A shaft hole is opened at the lower part of the outer surface of the screw 502, and a handle rod 5021 is inserted into the shaft hole. A positioning seat 3041 is installed at the top of the vertical part of the frame 304. The upper surface of the positioning seat 3041 has multiple fixing holes 3043. A reinforcing rib plate 3042 is installed on the lower surface of the positioning seat 3041 near the L-shaped frame 304. The end of the reinforcing rib plate 3042 away from the positioning seat 3041 is connected and fixed to the L-shaped frame 304. The reinforcing rib plate 3042 improves the mechanical strength of the connection between the positioning seat 3041 and the L-shaped frame 304. The positioning seat 3041 is installed at the required position using bolts to limit the position of the L-shaped frame 304.

[0024] Rotating the screw 502 causes the top block 501 to move up and down. The second inclined surface 5011 of the top block 501 slides into contact with the first inclined surface 503 of the triangular block 500, pushing the triangular block 500 to move laterally. This, in turn, causes the two gates 400 to slide synchronously in opposite directions. One gate 400 opens to increase the water flow channel of the cooling water pipe 303, while the other gate 400 closes to decrease the water flow channel of the return pipe 302, or vice versa. This fine-tuning method can control the amount of cooling water flowing to the mold. For example, when the mold temperature is slightly higher than the target value, the fine-tuning gate 400 slightly increases the flow rate of the cooling water pipe 303 to quickly remove excess heat; when the temperature is close to the target value, the flow rate of the cooling water pipe 303 is reduced to maintain a stable temperature. Compared to the crude method of relying solely on the circulation pump 202 for regulation, this method achieves stepless control of the cooling water flow, improves the accuracy of mold temperature control, and allows cooling water that does not flow to the mold to return to the spray tower 102 through the return pipe 302. After being cooled by the spray tower 102, it flows back into the collection tank 100 to participate in the next cycle, avoiding the waste of water resources caused by direct discharge of cooling water. The vents and fans at the top of the spray tower 102 can accelerate the cooling of the water, ensuring that the temperature of the return cooling water drops to a suitable range, providing a guarantee for recycling. This closed-loop design reduces water consumption and wastewater discharge, meeting the requirements of energy conservation and environmental protection.

[0025] The vertical part of the L-shaped frame 304 is equipped with two horizontally arranged tubes 602. A telescopic rod 601 is inserted inside each tube 602, with one end of the telescopic rod 601 on the outside of the tube 602 connected to a triangular block 500. A compression spring 600 is fitted onto the structure formed by the telescopic rod 601 and the tube 602, with both ends of the compression spring 600 contacting the L-shaped frame 304 and the triangular block 500, respectively. A cover 700 is installed on the vertical part of the L-shaped frame 304 away from the tubes 602. Two connecting holes 3044 are provided in the area of ​​the vertical part of the L-shaped frame 304 covered by the cover 700. The connecting holes 3044 communicate with the internal space of the cover 700 and the corresponding internal space of the tube 602. The telescopic rod 601 is located inside the tube 602. A piston 6011 is installed at one end of the tube 602, and the piston 6011 is slidably installed inside the tube 602; a vertical hole is opened on the horizontal part of the L-shaped frame 304, and a vertical tube 702 is installed in the vertical hole. A bent tube 701 is installed at the lower part of the vertical tube 702, and the end of the bent tube 701 away from the vertical tube 702 is connected to the cover 700; a rubber plug 7033 is slidably installed inside the vertical tube 702, and a push rod 7032 is installed at the middle of the upper surface of the rubber plug 7033. A support plate 7031 is fixedly connected to the upper end of the push rod 7032, and an arc plate 703 is installed at the end of the support plate 7031 away from the push rod 7032. The arc plate 703 is wrapped around the screw 502 and is located on the side of the screw 502 away from the vertical part of the L-shaped frame 304. When screw 502 is turned, screw 502 drives top block 501 to move up and down, thereby causing triangular block 500 to move laterally. Combined with the rebound force of compression spring 600, this achieves stable lateral movement of triangular block 500. Telescopic rod 601 and tube 602 work together to support compression spring 600. After the amount of compression of compression spring 600 changes, the fluid medium inside tube 602 enters and exits the casing 700 through connecting hole 3044 under the action of piston 6011. Because casing 700 is connected to vertical tube 702 via bent pipe 701, rubber plug 7033 moves up and down inside vertical tube 702. Rubber plug 7033, through top rod 7032, drives arc plate 703 to move up and down along screw 502. At this time, arc plate 703 and other components work together to support screw 502, reducing the impact of the rebound force of compression spring 600 on screw 502 and protecting screw 502.
