Description
Technical Field
[0001] The present invention relates to the technical field of injection molds, and specifically to an injection mold with intelligent temperature control function. Background Technique
[0002] Injection molds are important equipment for industrial production. Their structures are complex, and the costs of design and manufacturing are relatively high. The object of operation of injection molds is molten plastic. Injection molding, also known as injection molding, is a molding method that combines injection and molding. Injection molding is a processing method used when mass-producing some parts with complex shapes. Specifically, it means injecting the heat-melted plastic into the mold cavity under high pressure by an injection molding machine, and after cooling and solidifying, obtaining the molded product. The advantages of the injection molding method are fast production speed, high efficiency, automated operation, a variety of colors and patterns, shapes that can range from simple to complex, sizes that can range from large to small, and the molded products have precise dimensions, are easy to update, and can form parts with complex shapes.
[0003] However, in existing injection molds, due to the relatively cold inner wall temperature of the mold cavity, the molten plastic will condense and adhere when it encounters the inner wall of the injection cavity, and there is no temperature control for the mold, resulting in a large temperature difference before and after injection, thus affecting the subsequent demolding and molding quality. Summary of the Invention
[0004] The purpose of the present invention is to provide an injection mold with intelligent temperature control function to solve the problems raised in the prior art.
[0005] To achieve the above purpose, the present invention provides the following technical solutions:
[0006] An injection mold with intelligent temperature control function includes an upper mold and a lower mold. An injection port is arranged inside the upper mold, an injection cavity is arranged inside the lower mold, the injection port is communicated with the injection cavity, and a temperature control device is jointly formed inside the upper mold and the lower mold.
[0007] Preferably, two groups of ventilation grooves are symmetrically arranged inside the upper mold. An air delivery pipe is arranged on one side of the ventilation groove close to the injection port. The air delivery pipe is arranged outside the injection port. A vertical groove is arranged on the side of the ventilation groove away from the air delivery pipe. An air inlet is arranged at the top of the ventilation groove, and a one-way valve is arranged inside the air inlet.
[0008] Preferably, a flow groove is arranged inside the lower mold. Both ends of the flow groove are communicated with the vertical groove. A ventilation pipe is arranged on one side of the lower mold close to the center of the flow groove. The ventilation pipe is connected to an external air pump, and an electric heating wire is arranged on the inner wall of the ventilation pipe;
[0009] Air is pumped out through an external air pump, so that the gas in the injection cavity flows through the small holes to the air duct, then to the ventilation groove, and finally, together with the gas input through the air inlet at the top of the ventilation groove, it is transported to the flow groove through the vertical groove, thus realizing the heat dissipation of the injection cavity. When the injection cavity needs to be preheated before injection, the electric heating wire is turned on, and the external air pump is used to transport gas into the flow groove. After the gas is affected by the heat of the electric heating wire, it is transported into the flow groove, causing the temperature in the flow groove to rise. Coupled with the closure of the ventilation pipe and the closure plate, a closed space is formed in the flow groove. After the connecting rod expands due to heat, the space in the flow groove is further compressed, and thus the gas pressure in the flow groove further increases, causing the gas temperature in the flow groove to also rise, achieving an increase in gas heat without changing the power of the electric heating wire.
[0010] Preferably, the flow groove is composed of several straight grooves and polygonal grooves. The polygonal grooves are located on the side of the straight grooves close to the injection cavity, and the cross-section of the polygonal grooves is trapezoidal.
[0011] Preferably, several moving plates are arranged in the polygonal grooves. The moving plates are slidably connected to the polygonal grooves, and connecting rods are arranged between the moving plates and the polygonal grooves. The connecting rods are memory metals;
[0012] By arranging the connecting rods and utilizing the special property of the connecting rods being memory metals, when injection molding is carried out in the injection cavity, the heat of the molten plastic is transferred to the connecting rods through the lower mold, causing the connecting rods to expand due to heat. Then, the connecting rods push the moving plates to move towards the side close to the straight grooves, and thus the flow spacing of the flow groove is compressed. When the external air pump is exhausting air, the flow space of the gas in the flow groove is reduced, and thus the flow velocity of the gas in the flow groove increases. Without changing the power of the external air pump, the improvement of the flow velocity is completed, thereby saving energy consumption. Moreover, after the gas flow velocity increases, the heat exchange efficiency between the gas and the moving plates can be improved, so as to quickly take away the heat in the injection cavity and improve the injection molding effect;
[0013] When the temperature in the injection cavity is relatively low, at this time, the connecting rods contract and reset, driving the moving plates to move towards the side close to the injection cavity, increasing the flow spacing in the flow groove. Then, the flow velocity of the gas in the flow groove decreases, reducing the heat exchange efficiency between the gas and the moving plates, and thus insulating the remaining temperature in the injection cavity, preventing the inner wall from being too cold when the next injection molding is carried out, which may cause the molten plastic to solidify prematurely and affect the injection molding quality.
[0014] By setting the moving plates in a trapezoidal shape, the contact area between the gas and the moving plates is increased, and several pneumatic plates are also arranged on the moving plates to further increase the contact area between the gas and the moving plates;
[0015] By changing the expansion or contraction of the connecting rod through temperature, the flow spacing of the flow channel is changed, thereby adjusting the gas flow rate, achieving a change in the heat exchange efficiency, and thus achieving the effect of intelligent temperature control.
[0016] Preferably, a corrugated plate is provided between the moving plate and the polygonal groove, and a corrugated plate is also provided between adjacent two moving plates;
[0017] The moving plate moves under the action of the connecting rod. When the moving plate moves, it will drive the corrugated plate to move. Thus, when the flow channel changes the spacing, leakage will not occur, thereby preventing gas from flowing into the space between the moving plate and the injection cavity, and avoiding the phenomenon that the flow rate cannot be changed.
[0018] Preferably, the vertical groove is composed of a cylindrical tube and a polygonal tube. The polygonal tubes correspond to the polygonal grooves one by one. A driven plate is arranged in the vertical groove. A magnet is arranged on the side of the driven plate opposite to the moving plate. The driven plate is connected to the moving plate through the magnet, and the driven plate is slidably connected to the vertical groove;
[0019] After the upper mold and the lower mold are closed, the magnet on the moving plate attracts the magnet on the driven plate. Then, the driven plate and the moving plate are integrated. When the moving plate moves, the moving plate will drive the driven plate. Through the movement of the moving plate and the driven plate, the flow spacing of the vertical groove and the flow channel is adjusted, so as to achieve different flow spacings, thereby changing the gas flow rate. By changing the flow rate, the heat dissipation effect in the injection cavity is changed, so as to achieve the effect of intelligent temperature control.
[0020] Preferably, a plurality of pneumatic vanes are arranged on the side of the moving plate close to the straight groove. The axis of the pneumatic vane forms an angle with the axis of the moving plate. A pull rope is arranged at the bottom of the pneumatic vane, and a gravity ball is arranged on the side of the pull rope away from the pneumatic vane;
[0021] When the gas flows through the flow channel, the gas will encounter the pneumatic vane, and the gas will exert a certain push on the pneumatic vane. Then, the pneumatic vane will move under the pushing action of the gas. The pneumatic vane will move to the side close to the gas delivery direction. When the pneumatic vane moves, it will drive the gravity ball to move. Then, during the movement of the gravity ball, it will be subject to the force of falling downward, and it will also be affected by the gas push and swing. And the pneumatic vane has a certain elasticity. Then, the pneumatic vane will drive the gravity ball to move. During the swinging process of the gravity ball, the gravity ball will randomly impact the moving plate, and the impact-generated gravity will be transmitted to the injection cavity through the moving plate. Then, the vibration will cause the gas attached to the inner wall of the injection cavity to separate from the injection cavity. Then, the gas will move to the side close to the air duct, thereby achieving the effect of vibration exhaust, and avoiding the residual gas in the injection cavity from affecting the quality of injection molding.
[0022] Preferably, a plurality of closing plates are provided on the side of the injection port close to the injection cavity, a receiving cavity is provided on the side of the closing plate close to the upper mold, an electromagnet is provided in the receiving cavity, a magnetic conductor is provided on the side of the closing plate close to the receiving cavity, and the closing plate is slidably connected to the receiving cavity;
[0023] The controller controls the electromagnet to pass positive or reverse electricity, so that the magnetic pole of the electromagnet close to the closing plate changes, thereby generating a repulsive or attractive effect with the magnetic pole of the magnetic conductor in the closing plate, thereby moving the closing plate along the receiving cavity, and realizing the closing and opening of the closing plate;
[0024] When injection molding is required, the closing plate is opened to connect the injection port with the injection cavity, and the molten plastic is transported to the injection cavity through the injection port to complete the injection molding. When the injection molding is completed, the closing plate is closed to achieve the function of the closing plate to isolate the injection port and close the injection port. At the same time, since the air duct is arranged outside the injection port, when the ventilation duct transports high-temperature gas to the flow groove, the high-temperature gas can be transported to the vertical groove through the flow groove, and then transported to the air duct through the ventilation groove. At this time, the high-temperature gas in the air duct can be transferred to the molten plastic through the injection port, thereby avoiding the phenomenon of the molten plastic solidifying when it encounters cold, thereby achieving the effect of keeping the molten plastic warm.
[0025] Preferably, a plurality of small holes are provided on one side of the closing plate close to the receiving cavity, the small holes are connected to the air supply pipe, and a one-way valve is provided in the small holes;
[0026] By setting the small hole, after the closing plate is closed, when the injection cavity needs to be vented, the gas in the injection cavity can be transported to the air duct through the small hole, so that the air in the injection cavity is discharged, thereby improving the injection molding quality of the molded workpiece; when it is necessary to reversely supply air to the air duct, due to the one-way valve in the small hole, the gas can only flow from the injection cavity to the air duct, and the one-way valve will block the gas from being transported from the air duct to the injection cavity, thereby preventing the gas from entering the injection cavity in the insulation state and interfering with the injection molding of the molded workpiece.
[0027] Compared with the prior art, the present invention has the following beneficial effects:
[0028] 1. By setting the movable plate into a trapezoid, the contact area between the gas and the movable plate is increased, and a number of wind blades are also provided on the movable plate to further increase the contact area between the gas and the movable plate; the expansion or contraction of the connecting rod is changed by temperature, thereby realizing the change of the flow spacing of the flow groove, thereby adjusting the flow rate of the gas, realizing the change of the heat exchange efficiency, and realizing the effect of intelligent temperature control.
[0029] 2. The gas will encounter the wind-driven piece, and the gas will exert a certain pushing force on the wind-driven piece. As a result, the wind-driven piece will move under the pushing action of the gas. The wind-driven piece will move towards the side closer to the gas delivery direction. When the wind-driven piece moves, it will drive the gravity ball to move. During the movement of the gravity ball, it will be subjected to a downward falling force and will also swing under the influence of the gas push. Moreover, the wind-driven piece has a certain elasticity. Therefore, the wind-driven piece will drive the gravity ball to move. During the swinging process of the gravity ball, the gravity ball will randomly impact the moving plate, and the impact-generated gravity will be transmitted to the injection cavity through the moving plate. Then, the vibration will cause the gas attached to the inner wall of the injection cavity to separate from the injection cavity. Subsequently, the gas will move towards the side closer to the air duct, thereby achieving the effect of vibration exhaust, avoiding the residue of gas in the injection cavity and affecting the quality of injection molding.

[0048] As a specific embodiment of the present invention, a corrugated plate is arranged between the moving plate 24 and the polygonal groove 222, and a corrugated plate is also arranged between adjacent two moving plates 24.
[0049] As a specific embodiment of the present invention, a plurality of pneumatic vanes 25 are arranged on the side of the moving plate 24 close to the straight groove 221. The axis of the pneumatic vane 25 forms an angle with the axis of the moving plate 24. A pull rope 26 is arranged at the bottom of the pneumatic vane 25, and a gravity ball 27 is arranged on the side of the pull rope 26 away from the pneumatic vane 25.
[0050] The working principle of the present invention:
[0051] After the upper mold 1 and the lower mold 2 are closed, the magnets on the moving plate 24 attract the magnets on the driven plate 17, and then the driven plate 17 and the moving plate 24 are combined into one. When the moving plate 24 moves, the moving plate 24 will drive the driven plate 17. Through the movement of the moving plate 24 and the driven plate 17, the flow spacing of the vertical groove 14 and the flow groove 22 is adjusted, so as to realize different flow spacings, and then change the flow rate of the gas. By changing the flow rate, the heat dissipation effect in the injection cavity 21 is changed;
[0052] By controlling the electromagnet to conduct forward or reverse electricity through the controller, the magnetic pole of the electromagnet close to one side of the closing plate 18 is changed, and then the magnetic pole of the electromagnet repels or attracts the magnetic conductor in the closing plate 18, so as to realize the movement of the closing plate 18 along the receiving cavity 19, and realize the closing and opening of the closing plate 18;
[0053] When injection molding is required, the closing plate 18 is opened, so that the injection port 11 is connected with the injection cavity 21, and the molten plastic is transported to the injection cavity 21 through the injection port 11 to complete the injection molding. When the injection molding is completed, the closing plate 18 is closed, so that the closing plate 18 can separate the injection port 11 and close the injection port 11. At the same time, since the air delivery pipe 13 is arranged outside the injection port 11, when the ventilation pipe 23 transports high-temperature gas to the flow groove 22, the high-temperature gas can be transported to the vertical groove 14 through the flow groove 22, and then transported to the air delivery pipe 13 through the ventilation groove 12. At this time, the high-temperature gas in the air delivery pipe 13 can be transferred to the molten plastic through the injection port 11, thereby avoiding the phenomenon that the molten plastic solidifies when it encounters cold.
[0054] An external air pump is used to evacuate air so that the gas in the injection cavity 21 flows through the small hole to the air duct 13, and then flows through the air duct 13 to the ventilation slot 12, and finally, together with the gas input from the air inlet set at the top of the ventilation slot 12, it is transported to the flow slot 22 through the vertical slot 14, thereby realizing the heat dissipation of the injection cavity 21. When the injection cavity 21 needs to be preheated before injection molding, the electric heating wire is turned on and the gas is transported to the flow slot 22 by an external air pump, so that the gas is transported to the flow slot 22 after being affected by the heat of the electric heating wire, so that the temperature in the flow slot 22 rises, and the ventilation pipe 23 is closed, and the closing plate 18 is closed, so that a closed space is formed in the flow slot 22. After the connecting rod is heated and expanded, the space in the flow slot 22 is further compressed, and then the gas pressure in the flow slot 22 is further increased, so that the gas temperature in the flow slot 22 also increases accordingly;
[0055] By setting a connecting rod and utilizing the special property of the connecting rod being a memory metal, when injection molding is performed in the injection cavity 21, the heat of the molten plastic is transferred to the connecting rod through the lower mold 2, so that the connecting rod expands due to the heat, and then the connecting rod pushes the movable plate 24 to move to the side close to the straight groove 221, and then the flow spacing of the flow groove 22 is compressed, so that when the external air pump is evacuating, the flow space of the gas in the flow groove 22 is reduced, and then the flow velocity of the gas in the flow groove 22 is increased. Under the premise of not changing the power of the external air pump, the flow velocity is increased, thereby saving energy consumption, and after the gas flow velocity is accelerated, the heat exchange efficiency between the gas and the movable plate 24 can be enhanced, so that the heat in the injection cavity 21 is quickly taken away, and the injection molding effect is improved;
[0056] When the temperature in the injection cavity 21 is relatively low, the connecting rod contracts and resets at this time, driving the moving plate 24 to move towards the side close to the injection cavity 21, increasing the flow spacing in the flow groove 22. As a result, the flow velocity of the gas in the flow groove 22 decreases, reducing the heat exchange efficiency between the gas and the moving plate 24, thereby insulating the remaining temperature in the injection cavity 21. This prevents the inner wall of the injection cavity 21 from being too cold during the next injection, which could cause the molten plastic to solidify prematurely and affect the injection quality.
[0057] By setting the moving plate 24 in a trapezoidal shape, the contact area between the gas and the moving plate 24 is increased. Additionally, a number of pneumatic vanes 25 are provided on the moving plate 24 to further increase the contact area between the gas and the moving plate 24.
[0058] By changing the expansion or contraction of the connecting rod due to temperature, the flow spacing in the flow groove 22 is changed, thereby adjusting the flow velocity of the gas and achieving a change in the heat exchange efficiency.
[0059] When the gas flows through the flow groove 22, the gas will encounter the pneumatic vane 25, and the gas will exert a certain pushing force on the pneumatic vane 25. As a result, the pneumatic vane 25 will move under the pushing action of the gas. The pneumatic vane 25 will move towards the side close to the gas delivery direction. When the pneumatic vane 25 moves, it will drive the gravity ball 27 to move. During the movement of the gravity ball 27, it will be subject to a downward falling force and will also swing under the influence of the gas push. Moreover, the pneumatic vane 25 has a certain elasticity, so the pneumatic vane 25 will drive the gravity ball 27 to move. During the swinging process of the gravity ball 27, the gravity ball 27 will randomly impact the moving plate 24, and the impact-generated gravity will be transmitted to the injection cavity 21 through the moving plate 24. As a result, the vibration will cause the gas attached to the inner wall of the injection cavity 21 to separate from the injection cavity 21, and then the gas will move towards the side close to the air duct 13, thereby achieving the effect of vibration exhaust and preventing the gas from remaining in the injection cavity 21.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present invention.
