Description

Technical Field

[0001] This utility model relates to the technical field of molding mechanisms, specifically to a heat-pressing and shaping mechanism for plastic parts. Background Technology

[0002] Plastic parts refer to a material with high plasticity. By heating and pressurizing, it can be shaped according to the shape of the mold, which is also one of the common shaping methods. In order to ensure the shaping effect, heat holding technology is usually used to keep the pressure and heat for a period of time to ensure the stability of the shaping and reduce rebound.

[0003] The molds of current shaping mechanisms are relatively fixed. Each production can only proceed after the previous plastic part has been shaped, cooled, and unloaded. This process cannot be continuous, which greatly reduces production efficiency. In addition, the current cooling methods are relatively common, with poor cooling rate and effect. Therefore, a heat-holding and shaping mechanism for plastic parts is proposed. Utility Model Content

[0004] The technical solution adopted by this utility model to solve the technical problem is: a plastic part heat-sealing and shaping mechanism, including a processing table, a guide rail is detachably embedded in the middle of the top side wall of the processing table, two sliders are slidably connected in the guide rail, a telescopic rod is embedded in the middle of the sliders, a support plate is detachably connected to the output end of the telescopic rod, a pin is fixedly connected to the side wall of the support plate away from the telescopic rod, a mold is set above the support plate, and a slot is opened on the bottom side wall of the mold and the side wall opposite to the pin, and the pin is inserted into the slot.

[0005] As a preferred technical solution of this utility model, water tanks are provided at the bottom of both ends of the guide rail. An output pipe is detachably connected to one side of the water tank and near the bottom side wall. A connecting hose is fixedly connected to the top of the output pipe. A recycling pipe is detachably connected to the water tank away from the output pipe and near the top edge.

[0006] As a preferred technical solution of this utility model, the top ends of the output pipe and the recovery pipe are both fixedly connected with connecting hoses, and the two side walls of the mold that are far apart from each other are fixedly connected with external pipes. One end of the connecting hose is detachably connected to the external pipe.

[0007] As a preferred technical solution of this utility model, three water grooves are provided in the four side walls of the mold, and one end of the outer pipe extends into the two side walls of the mold. All three water grooves are connected to the outer pipe.

[0008] As a preferred technical solution of this utility model, the top of the processing table and the two side walls near the guide rail are fixedly connected to support columns. The mold is attached to the top side wall of the support column through the bottom. A hydraulic cylinder is detachably connected to the middle of the top side wall of the processing table. The output end of the hydraulic cylinder is detachably connected to a heating pressing plate through the top side wall of the processing table. A heating component is connected inside the heating pressing plate.

[0009] This utility model has the following advantages: because a guide rail is connected to the processing table, and two sliders are slidably connected on the guide rail, and each slider is opposite to a mold, when the mold is shaped, it can be removed by the slider. At the same time, the empty mold can be moved to the support column to continue production.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Please refer to the following: Figure 1-3 This utility model discloses a heat-sealing and shaping mechanism for plastic parts, including a processing table 1. A guide rail 3 is detachably embedded in the middle of the top side wall of the processing table 1. Two sliders 11 are slidably connected in the guide rail 3. A telescopic rod 12 is embedded in the middle of the sliders 11. A support plate 13 is detachably connected to the output end of the telescopic rod 12. A pin 14 is fixedly connected to the side wall of the support plate 13 away from the telescopic rod 12. A mold 4 is set above the support plate 13. A slot 15 is opened on the bottom side wall of the mold 4 and the side wall opposite to the pin 14. The pin 14 is inserted into the slot 15.

[0016] Water tanks 5 are provided at the bottom of both ends of the guide rail 3. An output pipe 6 is detachably connected to one side of the water tank 5 near the bottom side wall. A connecting hose 8 is fixedly connected to the top of the output pipe 6. A recovery pipe 7 is detachably connected to the water tank 5 away from the output pipe 6 and near the top edge. The tops of both the output pipe 6 and the recovery pipe 7 are fixedly connected to the connecting hose 8. An external pipe 17 is fixedly connected to the two side walls of the mold 4 that are far apart from each other. One end of the connecting hose 8 is detachably connected to the external pipe 17. Three water troughs 16 are opened in the four side walls of the mold 4. One end of the external pipe 17 extends into the two side walls of the mold 4. All three water troughs 16 are connected to the external pipe 17.

[0017] The technical effect of this solution is as follows: the empty mold 4 is moved and placed on the support column 2 by the slider 11. After the plastic part in the mold 4 is produced, it is removed by the slider 11. At the same time, the new mold 4 is moved to the support column 2 to continue production. By repeating this process, the function of continuous production can be achieved, which can effectively improve the production efficiency. The set-in column 14 can effectively position the mold 4, ensure the stability of the mold 4 during the movement, and ensure the smooth progress of production.

[0018] Support columns 2 are fixedly connected to the top of the processing table 1 and the two side walls near the guide rail 3. The mold 4 is attached to the top side wall of the support column 2 through the bottom. A hydraulic cylinder 9 is detachably connected to the middle of the top side wall of the processing table 1. The output end of the hydraulic cylinder 9 is detachably connected to a heating pressing plate 10 through the top side wall of the processing table 1. A heating component is connected inside the heating pressing plate 10.

[0019] The technical effect of this solution is as follows: the mold 4 that has been moved out is connected to one end of the connecting hose 8 through the external pipe 17. In this way, cooling water can be sent into the water tank 16 through the output pipe 6. The water flowing in the water tank 16 can efficiently cool the mold 4 and improve the cooling efficiency. Since the three water tanks 16 are evenly distributed on the mold 4, the uniformity of cooling can be guaranteed, which is convenient for demolding after cooling and positioning.

[0020] Specifically, in use, the raw material is placed on the mold 4, and then the hydraulic cylinder 9 is activated to drive the heating pressing plate 10 to descend and finally press it into the mold 4. The heating component installed in the heating pressing plate 10 is activated to achieve the effect of hot pressing. After the pressure reaches the specified value, it is maintained for a period of time. During this period of time, the pressure is changed in real time according to the actual situation to ensure stable pressing of the plastic part and continuous heating. After shaping, the heating pressing plate 10 is raised, and then the telescopic rod 12 is activated to push the support plate 13 upward and insert the insertion post 14 into the slot 15. Finally, the mold 4 is lifted from the support post 2 and removed by the slider 11. At the same time, the empty mold 4 is moved to the support post 2 for production. One end of the connecting hose 8 is connected to the outer pipe 17 on the removed mold 4, and then cooling water is sent into the water tank 16. The water is ensured to flow in the water tank 16 and finally enters the water tank 5 through the recovery pipe 7 to achieve the effect of cooling water flow, thereby improving the cooling effect. Because the cooling water is evenly distributed, it ensures smooth demolding after cooling.
