Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 6, the invention provides a negative pressure type temperature-controlled cooling device for an automobile injection molding part, which comprises a cooling chamber 1, wherein a temperature-controlled device 2 is arranged in the cooling chamber 1, the temperature-controlled device 2 comprises a negative pressure suction fan 201 and a vortex tube 202, the vortex tube 202 is provided with a temperature-controlled valve 203, an air inlet 204, a cold air outlet 205 and a hot air outlet 206, the negative pressure suction fan 201 is connected with the air inlet 204, the hot air outlet 206 is connected with a hot air pipeline 207, and the hot air pipeline 207 extends to the outside of the cooling chamber 1.

The invention uses vortex tube 202 to refrigerate, and the vortex tube 202 is an energy separation device with simple structure, which is composed of nozzle, vortex chamber, separation orifice plate and cold and hot two-end tube. In operation, gas enters the vortex tube at a high velocity in a tangential direction. When the airflow rotates at a high speed in the vortex tube, the airflow is separated into two parts of airflow with unequal total temperature after vortex conversion, the temperature of the airflow at the central part is low, the temperature of the airflow at the outer part is high, and the ratio of cold flow to hot flow can be adjusted through the temperature control valve 203, so that the optimal refrigeration effect or heating effect is obtained, and the effect of temperature control and cooling is further achieved. When the vortex tube 202 is used in the present invention, the hot gas produced by the vortex tube is removed, and the cold gas is retained in the cooling chamber 1 for cooling the injection-molded parts.

As shown in fig. 1 and 2, in the present invention, flow guiding devices 3 are disposed at four corners of a cooling chamber 1, each flow guiding device 3 includes a flow guiding plate 301 and a flow guiding seat 302 fixed on an inner wall of the cooling chamber 1, the flow guiding plate 301 is disposed in an inclined manner, and forms a triangular structure with a corner of the cooling chamber 1, the flow guiding seat 302 is connected to a flow guiding cylinder 303, one end of the flow guiding cylinder 303 is provided with a trumpet-shaped air inlet cylinder 304, a flow guiding frame 305 is disposed in the flow guiding cylinder 303, the flow guiding frame 305 is provided with a flow guiding rotating shaft 306 and a flow guiding driving motor 307 for driving the flow guiding rotating shaft 306 to rotate, and the flow guiding rotating shaft.

In the above-mentioned flow guiding device 3, the flow guiding plate 301 can reflect the passing cold air to the next flow guiding plate 301, the flow guiding rotating shaft 306 and the flow guiding blades 308 are disposed between the flow guiding plate 301 and the next flow guiding plate 301, and when the flow guiding driving motor 307 works, the flow guiding rotating shaft 306 and the flow guiding blades 308 can rotate, so as to drive the cold air to move, and the cold air can flow to the next flow guiding plate 301. According to the invention, by arranging the flow guide device 3, the cold air produced by the vortex tube 202 is sprayed on one of the flow guide plates 301, moves to the next flow guide plate 301 through the reflection action of the flow guide plate 301, and then provides power for the flow of the cold air through the rotation of the flow guide blades 308. The flow guiding device 3 is divided into four parts which are respectively arranged at four corners of the cooling chamber 1, and cold air can circularly flow in the cooling chamber 1 under the action of the flow guiding device 3 and finally enters the negative pressure suction fan 201 from the air inlet 204 for circulation.

as can be seen from the above description, when the cooling chamber 1 of the present invention works, the cooling air circulates inside, the cooling air is generated by the vortex tube 202, and when passing through the injection molded part, the cooling air takes away heat from the injection molded part, so that the injection molded part is cooled, and after taking away the heat from the injection molded part, the cooling air enters the vortex tube 202 again for recirculation. The flowing air can take away the heat on the injection molding part, and the flowing air is cold air, so that the injection molding part can be cooled more effectively, and the cooling effect of the device on the injection molding part is good.

As shown in fig. 1, 3 and 4, in the present invention, a conveyor belt 4 is disposed in the cooling chamber 1, a turning device 5 is disposed on the conveyor belt 4, the turning device 5 includes an installation base 501 disposed on the conveyor belt 4 and moving together with the conveyor belt 4, a turning rotating shaft 502 is rotatably disposed on the installation base 501 in a penetrating manner, a turning motor 503 and a turning frame 504 are respectively disposed at two ends of the turning rotating shaft 502, and the turning motor 503 is fixed on the installation base 501.

In the invention, the injection molding part is conveyed by the conveyor belt 4 to move to a designated place, and the temperature control device 2 cools the injection molding part during the conveying process of the injection molding part. However, in the cooling treatment process of the injection molding part, the injection molding part is placed on the conveyor belt 4, the heat on the upper end surface of the injection molding part is easily taken away by flowing cold air, and the lower end surface of the injection molding part is tightly attached to the conveyor belt and is not in contact with the air, so that the heat on the injection molding part is not easily dissipated, and the surface of the injection molding part tightly attached to the conveyor belt is not easily cooled, thereby affecting the cooling effect of injection molding. In order to avoid the situation, the turnover device 5 is arranged, and the turnover device 5 can turn over the injection molding piece by 180 degrees when the conveyor belt 4 conveys the injection molding piece, so that one surface of the injection molding piece, which is tightly attached to the conveyor belt, faces upwards, the heat dissipation speed of the injection molding piece is accelerated, the injection molding piece can dissipate heat without dead angles, and the cooling effect of the temperature control cooling device is enhanced.

In the above description, when the injection-molded part is placed on the carrier rack 506 connected to the fixing frame 505, the other carrier rack 506 is located above the injection-molded part and on the same vertical line, so that it is possible to prevent the cold air from flowing to the upper end surface of the injection-molded part. Based on the above requirement, the retractable rod 509 is retracted into the retractable chute 508. While the output end of the elevating cylinder 511 is in a retracted state under the above conditions. When the injection molding part needs to be turned over, the telescopic rod 509 extends out of the telescopic chute 508 to push the lifting seat 510, the lifting cylinder 511 and the other carrying net rack 506 to move towards the region right above the carrying net rack 506 below. When the lifting base 510 moves directly above the lower carrier rack 506, the output end of the lifting cylinder 511 extends out, so that the upper carrier rack 506 moves toward the lower carrier rack 506. Because the injection molding piece is placed on the lower loading net rack 506, when the lower end of the upper loading net rack 506 touches the injection molding piece, the lifting cylinder 511 stops moving. Under the above state, the position of the injection molding is fixed, and then the operation of the turnover motor 503 is controlled to drive the turnover rotating shaft 502 and the turnover frame 504 to rotate, so that the two carrier net racks 506 rotate, the injection molding between the two carrier net racks 506 rotates, and the injection molding is turned over by 180 degrees by controlling the rotation angle of the turnover motor 503.
