Description
Technical Field
[0001] This invention relates to the field of injection mold equipment technology, specifically to an intelligent temperature control and regulation device for precision injection molds for automotive buttons. Background Technology
[0002] Injection molding is a plastic processing method in which plastic is plasticized in a heated barrel of an injection molding machine and then injected into the cavity of a closed mold by a plunger or reciprocating screw to form a finished product. This method can process products with complex shapes, precise dimensions, or inserts, and offers high production efficiency. Most thermoplastics and some thermosetting plastics (such as phenolic plastics) can be processed using this method. The material used for injection molding must have good flowability to fill the mold cavity and obtain the final product.
[0003] Patent CN108215100B discloses a rapid temperature regulation device for a temperature-controlled injection mold, comprising a cold water tank and a hot water tank. The heat exchange chamber of the mold body has an inlet pipe at its inlet port and a return pipe at its outlet port. The inlet pipe is connected to a water supply pipe via a two-way valve. The right end of the water supply pipe is connected to a primary water pump, the suction end of which extends into the cold water tank. A buffer tank and a mixing tank are sequentially mounted on the water supply pipe from left to right. A temperature sensor is installed on the water supply pipe between the buffer tank and the mixing tank. Hot water is located at the lower end of the mixing tank. The hot water inlet is connected to the No. 2 water pump via a hot water pipe. The inlet of the water pump extends into the hot water tank. A three-way valve is installed on the return pipe. The cold water port of the three-way valve has a cold water return pipe connected to the return port of the cold water tank. A reflux control valve is installed on the cold water return pipe near the three-way valve. A hot water reflux pipe is installed at the hot water port of the three-way valve, connected to the return port of the hot water tank. A reflux control valve is also installed on the hot water reflux pipe near the three-way valve. An electric auxiliary heating component is also installed inside the buffer tank for heating the water. Cold water is supplied to the mixing tank via the No. 1 water pump, and hot water is supplied to the mixing tank via the No. 2 water pump. The water is then mixed to a preset temperature, which is lower than the pre-mixed temperature. A temperature sensor detects the temperature. The mixed water then enters the buffer tank, where it is heated based on the temperature sensor readings, facilitating temperature control.
[0004] Although the above technical solutions can cool down the mold by controlling the temperature of the cooling water, the cooling water entering the mold will still have a temperature difference between the inlet and outlet, which cannot quickly unify the cooling temperature inside the mold, thus affecting the molding of the product. Therefore, there is an urgent need for an intelligent temperature control and adjustment device for precision injection molds for automotive buttons to solve the above problems.

[0024] Compared with the prior art, the beneficial effects of the present invention are:
[0025] (1) Intelligent temperature control device for precision injection mold of automotive buttons: When the mold is cooled by the external cooling mechanism of the main tube and the cavity is cooled by the flow channel assembly, the cooling water in the second flow channel is simultaneously introduced into the channel for circulation, thereby cooling the inlet hole at the same time, avoiding the temperature at the inlet hole from affecting the cavity and improving the consistency of cooling.
[0026] (2) The intelligent temperature control device for precision injection mold of automotive buttons can drive the movable cylinder ring of the second flow channel to shift inward, thereby adjusting the spacing of the second flow channel connected in the middle of the cavity. Through the control of the slide rail and the locking post, the spacing of the second flow channel can be dynamically adjusted according to the wall thickness of the plastic part, improving the flexibility of cooling.
[0027] (3) Intelligent temperature control device for precision injection mold of automotive buttons: A baffle is connected to the same side of the exhaust pipe through a rotating shaft in the second flow channel where the exhaust pipe is installed. When the coolant enters and flows through it, the baffle flips towards the exhaust pipe under the action of the coolant. In conjunction with the breathable membrane, it prevents the coolant from leaking out through the exhaust pipe and improves exhaust safety.
[0028] (4) Intelligent temperature control device for precision injection mold of automotive buttons: The upper wall of the cylinder section on the upper surface of the second flow channel is pointed and convex. The asymmetrical trapezoidal structure with narrow upper part and wide lower part utilizes the difference between the density of coolant and air to form gas-liquid stratification driven by natural buoyancy. In the process of coolant flow, an exhaust channel is formed to promote the gas in the flow channel component to be discharged through the exhaust pipe, improve the smoothness of coolant flow, and thus improve the coolant introduction speed.
[0029] (5) Intelligent temperature control device for precision injection mold of automotive buttons: coolant is pumped in through the flow channel component. The flow channel components at both ends of the cavity are synchronously injected to form a bidirectional propulsion flow field, so that the contact area between the coolant and the inner surface of the mold reaches twice that of single-end injection in the initial stage. The full coverage time of the coolant is shortened, laying the time foundation for subsequent uniform cooling.
[0030] (6) Intelligent temperature control device for precision injection mold of automotive buttons, combined with the air pressure conditions in the flow channel assembly, can enable the coolant to quickly reach the liquid entry blind zone, avoid the problem of local overheating of the cavity due to end flow stagnation, improve the wetting speed of the dead corner area of the cavity, and eliminate the cooling delay in the initial stage.
[0031] (7) Intelligent temperature control device for precision injection mold of automotive buttons. The cooling mechanism connected at both ends simultaneously extracts the water. During this time, the air-cooling mechanism can draw in cold air from the outside to slowly cool the water and fill the cooling time gap caused by the extraction of the cooling water. The extraction operation can quickly discharge the high-temperature cooling water carrying a large amount of heat, avoiding it from stagnating in the flow channel components and forming a local high-temperature area. Then, the cooling mechanism will refill the water with new low-temperature cooling water to achieve efficient heat exchange, reduce the ineffective time of the cooling process, and further compress the cooling cycle.
[0032] (8) Intelligent temperature control device for precision injection mold of automotive buttons: The temperature of the cooling water that is reintroduced does not change drastically, avoiding overheating or cooling in the cavity, which would reduce product quality. The uniform cooling process ensures that the temperature changes of each part of the mold are consistent during the cooling stage, avoiding thermal stress concentration caused by uneven temperature, reducing the risk of damage such as cracks and deformation caused by thermal fatigue, and reducing the cost of mold replacement and maintenance.
[0033] (9) Intelligent temperature control device for precision injection mold of automotive buttons can reduce the running time and energy consumption of the refrigeration unit through a fast and efficient cooling cycle. The high-temperature cooling water extracted can be recycled after being cooled by the cooling mechanism, thereby improving the utilization rate of water resources, reducing the waste of industrial water, reducing the water cost and environmental pressure of enterprises, and reducing operating costs.
[0034] (10) Intelligent temperature control device for precision injection mold of automotive buttons. The efficient cooling cycle can promptly remove corrosive substances generated by chemical reaction between the cooling water and the mold material, reduce the degree of corrosion on the mold surface, maintain the smoothness of the mold surface, further extend the service life of the mold, and at the same time reduce product surface quality problems caused by mold corrosion, further improve the quality of the produced products.

[0068] The working principle of this invention is as follows:
[0069] A groove 205 is formed on the outer side of the cavity 202 of the mold 201. Two flow channel assemblies are constructed within the groove 205, symmetrically positioned on both sides of the cavity 202. The inner end of the main pipe 401 is fixedly connected to a spiral disc-shaped first flow channel 402, which is attached to the end face of the cavity 202. The end of the first flow channel 402 is fixedly connected to a spiral cylindrical second flow channel 403, which is wound around the side of the cavity 202. The two symmetrical flow channel assemblies... The components are connected by a V-shaped third flow channel 404. The part of the second flow channel 403 near the inlet hole 203 is connected through the channel 204. The mold 201 is connected to an external cooling mechanism 5 through the main pipe 401. When the cavity 202 is cooled by the flow channel assembly, the cooling water in the second flow channel 403 is simultaneously introduced into the channel 204 for circulation, thereby cooling the inlet hole 203 simultaneously, avoiding the temperature at the inlet hole 203 from affecting the cavity 202, and improving the consistency of cooling.
[0070] The upper surface of the mold 201 has mounting slots 207 with connecting channel grooves 205 on both sides. Each mounting slot 207 is fitted with a moving mechanism 3. The lower end of the locking post 303 is adapted to engage with the corresponding second flow channel 403. The locking post 303 can slide in the slide rail 301 through the slider 302, which can drive the movable cylinder of the second flow channel 403 to shift in 505, thereby adjusting the spacing of the second flow channel 403 connected in the middle of the cavity 202. Through the control of the slide rail 301 and the locking post 303, the spacing of the second flow channel 403 can be dynamically adjusted according to the wall thickness of the plastic part, improving the flexibility of cooling.
[0071] The upper bend of the fixed ring of the second flow channel 403 is fixedly connected to an exhaust pipe 405. The exhaust pipe 405 extends through the mold 201 and its opening is covered with a breathable membrane. At the same time, a baffle 406 on the same side as the exhaust pipe 405 is connected to the second flow channel 403 with the exhaust pipe 405 through a rotating shaft. When the coolant enters and flows through it, the baffle 406 is driven by the coolant to flip towards the exhaust pipe 405. With the help of the breathable membrane, the coolant is prevented from leaking out through the exhaust pipe 405, thus improving the exhaust safety.
[0072] The upper wall of the cylindrical section on the upper surface of the second flow channel 403 on the cavity 202 is a pointed protrusion. The asymmetrical trapezoidal structure, which is narrow at the top and wide at the bottom, utilizes the difference in density between the coolant and the air to form a gas-liquid stratification driven by natural buoyancy. This forms an exhaust channel during the flow of coolant, promotes the discharge of gas in the flow channel assembly through the exhaust pipe 405, improves the smoothness of coolant flow, and thus increases the coolant introduction speed.
[0073] By symmetrically arranging runner components on the outside of the cavity 202, and each runner component being connected to the cooling mechanism 5 via the main pipe 401, the cooling mechanisms 5 of the two runner components work simultaneously after injection molding. Coolant is pumped in through the runner components, and the runner components at both ends of the cavity 202 synchronously enter the liquid to form a bidirectional propulsion flow field. This makes the contact area between the coolant and the inner surface of the mold 201 twice that of single-end liquid entry in the initial stage, shortening the full coverage time of the coolant and laying the time foundation for subsequent uniform cooling.
[0074] For complex structures of the cavity 202 within the mold 201, such as deep grooves and thin-walled ribs, which are traditional blind spots for single-end liquid inlet, double-end liquid inlet allows the coolant to flow in opposite directions within the flow channel assembly. Combined with the air pressure conditions within the flow channel assembly, this allows the coolant to quickly reach the liquid inlet blind area, avoiding the problem of local overheating of the cavity 202 due to end-flow stagnation. This improves the wetting speed of the dead corner area of the cavity 202 and eliminates the cooling delay in the initial stage.
[0075] When the cooling water temperature rises, it is simultaneously extracted through the cooling mechanism 5 connected at both ends. During this time, the air-cooling mechanism 6 can draw in outside cold air to slowly cool it down, filling the cooling time gap caused by the extraction of cooling water. The extraction operation can quickly discharge the high-temperature cooling water carrying a large amount of heat, preventing it from stagnating in the flow channel components and forming a local high-temperature zone. Then, new low-temperature cooling water is immediately injected through the cooling mechanism 5 to achieve efficient heat exchange, reduce the ineffective time of the cooling process, and further compress the cooling cycle.
[0076] Through the rapid and efficient cooling cycle of the cooling mechanism 5, the requirements for cooling water temperature can be reduced while ensuring the cooling effect. After the cooling water is extracted, it is quickly passed through the refrigeration unit 504 activated in the water tank 501 and then reintroduced into the flow channel assembly. The temperature change of the reintroduced cooling water is not drastic, avoiding overheating or cooling in the cavity 202, which would reduce product quality. The uniform cooling process ensures that the temperature change of each part of the mold 201 is consistent during the cooling stage, avoiding thermal stress concentration caused by uneven temperature, reducing the risk of damage such as cracks and deformation of the mold 201 due to thermal fatigue, and reducing the replacement and maintenance costs of the mold 201.
[0077] Through a fast and efficient cooling cycle, the operating time and energy consumption of the chiller 504 can be reduced. The high-temperature cooling water extracted can be recycled after being cooled by the cooling mechanism 5, thereby improving water resource utilization, reducing industrial water waste, lowering enterprise water costs and environmental pressure, and reducing operating costs.
[0078] The efficient cooling cycle can promptly remove corrosive substances generated by the chemical reaction between the cooling water and the mold 201 material, reduce the degree of corrosion on the surface of the mold 201, maintain the surface smoothness of the mold 201, further extend the service life of the mold 201, and at the same time reduce product surface quality problems caused by the corrosion of the mold 201, thereby further improving the quality of the produced products.
