Description

Technical Field

[0001] This utility model relates to the field of blow molding technology, specifically a PET anti-deformation blow molding mold. Background Technology

[0002] The blow molding process for PET bottles, professionally known as hollow blow molding or blow molding, is a plastic processing method that uses gas pressure to inflate a hot-melt preform in a mold, thereby forming a hollow product. This method is widely used, as blow molding, which inflates a hot-melt preform using gas pressure, is low-cost, offers excellent molding performance, and is one of the fastest-growing methods in the plastics molding field. PET plastic raw materials are melted at high temperatures and then shaped into preforms. These preforms are then softened by heating to allow for stretch blow molding.

[0003] The existing equipment has the following problems when in use: During blow molding, the high temperature of the PET material is deformed due to the local low temperature of the mold. This deformation problem will seriously affect the quality and appearance of the PET bottle. Moreover, the local low temperature may also cause uneven flow of PET material in the mold, further affecting the uniformity of the bottle wall thickness and the overall structural strength. In addition, the subsequent maintenance and disassembly of the mold is extremely inconvenient, which increases the maintenance cost. Summary of the Invention

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution: Please refer to Figure 1 , Figure 2 , Figure 3A PET anti-deformation blow molding mold includes an mounting plate 1, a control chamber 12, a dual-output motor 6, and a preheating plate 7. The control chamber 12 is located on the top of the mounting plate 1. The dual-output motor 6 is located inside the control chamber 12. Lead screws 2 are fixedly connected to both sides of the dual-output motor 6. A slide block 3 is threaded onto the surface of the lead screw 2. A connecting rod 5 is connected to one side of the slide block 3. One end of the connecting rod 5 is connected to the preheating plate 7. A heating wire 8 is located inside the preheating plate 7. The connecting rod 5 is L-shaped. A guide rod 4 is located inside the control chamber 12. The guide rod 4 is slidably connected to the slide block 3. A heat-conducting plate 9, made of aluminum alloy, is located inside the semi-mold 11. When the dual-output motor 6 is started, driving the lead screw 2 to rotate, the lead screw 2, in conjunction with the slide block 3, moves along the guide rod 4 in a straight line. The linear motion causes the slide block 3 to move the connecting rod 5. The preheating plate 7 at one end of the connecting rod 5 and the half mold 11 move accordingly. The two sets of half molds 11 move relative to each other until they are in contact. They are heated by the heating wire 8 installed inside. The heat is quickly conducted to all parts of the half mold 11 through the heat conduction plate 9 to ensure that the half mold 11 is heated evenly. This preheating process prevents the PET material from deforming due to excessive temperature differences during blow molding. A temperature sensor is installed on the side wall of the half mold 11. The temperature sensor is connected to the control chip to monitor the temperature of the half mold 11 in real time and transmit the data to the control chip. The control chip adjusts the power of the heating wire 8 according to the preset temperature range so that the temperature of the half mold 11 is kept within a suitable range, thereby improving the processing quality.

[0027] Please see Figure 1 , Figure 2 , Figure 4 The preheating plate 7 has a slot 16 on one side, and a card plate 10 is engaged inside the slot 16. A half mold 11 is connected to one side of the card plate 10. An electric push rod 13 is provided on one side of the connecting rod 5. An insertion rod 14 is fixedly connected to the output end of the electric push rod 13. A slot 15 is provided on one side of the half mold 11. The slot 15 is adapted to the insertion rod 14. The card plate 10 on the half mold 11 is inserted into the slot 16, and the electric push rod 13 is activated to drive the insertion rod 14 into the slot 15 on the half mold 11. This can fix the half mold 11, facilitate the replacement of the half mold 11, improve the convenience of maintenance, and increase practicality.

[0028] Working principle: Insert the retaining plate 10 on the half mold 11 into the retaining slot 16. Start the electric push rod 13 to drive the insertion rod 14 into the slot 15 on the half mold 11, thereby fixing the half mold 11 and facilitating its replacement, improving maintenance convenience and practicality. When the dual-output motor 6 starts and drives the lead screw 2 to rotate, the lead screw 2, together with the slide block 3, moves linearly along the guide rod 4. This causes the slide block 3 to move the connecting rod 5, and the preheating plate 7 at one end of the connecting rod 5 moves with the half mold 11. The two sets of half molds 11 move relative to each other until they are in contact. At this time, the preheating... Plate 7 starts working, heating through the internal heating wire 8. The heat is quickly conducted to all parts of the semi-mold 11 through the heat conduction plate 9, ensuring that the semi-mold 11 is heated evenly. This preheating process prevents the PET material from deforming due to excessive temperature differences during blow molding. The temperature of the semi-mold 11 is monitored in real time by a temperature sensor, and the data is transmitted to the control chip. The control chip adjusts the power of the heating wire 8 according to the preset temperature range, so that the temperature of the semi-mold 11 is kept within a suitable range, thus improving the processing quality.
