Technical Field
[0001] This utility model relates to the field of locking mechanisms, and in particular to a mold frame closing locking mechanism. Background Technology
[0002] Blow molding machines are key equipment for producing bottles for various liquid packaging. These machines process plastic granules or pre-made preforms into hollow containers using a blow molding process. They are mainly used to produce various bottle-shaped packaging containers, such as mineral water bottles, beverage bottles, oil bottles, and pesticide bottles. The blow molding machine's mold frame consists of two mating mold frames. The blow molding die is divided into two halves and fixed to the two mold frames respectively. During operation, the two mold frames are locked together by a locking mechanism.
[0003] However, the existing locking mechanism is prone to mechanical wear due to frequent opening and closing of the mold frame and locking, which reduces its service life.
[0004] Therefore, it is necessary to provide a new mold frame closing and locking mechanism to solve the above-mentioned technical problems. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Please refer to the following: Figures 1 to 2 ,in, Figure 1 A schematic diagram of a preferred embodiment of the mold frame closing and locking mechanism provided by this utility model; Figure 2 for Figure 1 Structural diagram, second perspective view; Figure 3 for Figure 2 Enlarged view of part A of the structural schematic diagram; Figure 4 for Figure 2 Enlarged view of part B of the structural schematic diagram.
[0022] In the specific implementation process, such as Figure 1 and Figure 2 as well as Figure 4 As shown, a base 1 has a slot 2 on its top. A symmetrical first connecting block 5 and a second connecting block 6 are arranged within the slot 2. A first mold frame 7 and a second mold frame 8 are fixedly mounted on the first connecting block 5 and the second connecting block 6, respectively. A rotatable buckle plate 16 is provided on the first mold frame 7. A locking plate 24 that cooperates with the buckle plate 16 is fixedly mounted on the second mold frame 8. A symmetrical locking block 21 is fixedly mounted on one side of the buckle plate 16. A matching piece is provided on one side of the locking plate 24 to accommodate the symmetrical locking block 21. The card slot 25 has several through holes 22 through both sides of the symmetrical card block 21. A lubricating oil transmission mechanism is fixedly installed on the other side of the buckle plate 16. The lubricating oil transmission mechanism is connected to the several through holes 22. The lubricating oil transmission mechanism includes an oil tank 17. An oil pump 18 is fixedly installed on the oil tank 17. The output shaft of the oil pump 18 is fixedly connected to a main transmission pipe 19. Symmetrical auxiliary transmission pipes 20 are fixedly connected to both sides of the main transmission pipe 19. One end of the symmetrical auxiliary transmission pipe 20 passes through the buckle plate 16 and is connected to the inside of the symmetrical card block 21.
[0023] It should be noted that after the buckle plate 16 is driven to rotate and lock onto the locking plate 24, the symmetrical locking blocks 21 can be snapped into the symmetrical locking slots 25. After the oil pump 18 is started, the lubricating oil in the oil tank 17 can be pumped into the symmetrical locking blocks 21 through the auxiliary pipes 20 on both sides and finally flow out from several through holes 22. The flowing lubricating oil can lubricate the contact surface between the locking blocks 21 and the locking slots 25.
[0024] refer to Figure 1 and Figure 2 As shown, a motor 3 is fixedly installed on the wall of the slot 2 on one side. The output shaft of the motor 3 is fixedly connected to a bidirectional screw 4. One end of the bidirectional screw 4 is rotatably installed on the wall of the slot 2 on the other side. One end of the bidirectional screw 4 passes through the first connecting block 5 and the second connecting block 6. The first connecting block 5 and the second connecting block 6 are threaded on the bidirectional screw 4, and the first connecting block 5 and the second connecting block 6 are slidably installed in the slot 2.
[0025] It should be noted that motor 3 is preferably a servo motor. After motor 3 is started, it can drive the bidirectional screw 4 to rotate counterclockwise or clockwise, so that the first connecting block 5 and the second connecting block 6 on both sides can move towards each other and repel each other, thereby controlling the mold closing of the first connecting block 5 and the second connecting block 6.
[0026] refer to Figure 1 and Figure 2 As shown, symmetrical fixing blocks 10 are fixedly installed on both sides of the slot 2. A cylinder 11 is fixedly installed on the symmetrical fixing blocks 10. A pressing block 12 is fixedly installed on one end of the piston rod of the cylinder 11. Mounting pads 9 are fixedly installed on one side of the first mold frame 7 and the second mold frame 8. The mounting pads 9 are made of rubber. The central axis of the symmetrical pressing block 12 and the mounting pads 9 on both sides is the same horizontal line.
[0027] It should be noted that after the cylinders 11 on both sides are started, one end of their piston rods will move horizontally towards the mounting pads 9 on both sides, and finally the pressing block 12 will press tightly against the first mold frame 7 and the second mold frame 8 on both sides, which will enhance the stability of mold closing. The rubber material has good flexibility and friction performance, which can increase the friction between the pressing block 12 and the contact surface of the two mold frames, and at the same time avoid the pressing block 12 from causing friction damage to the two mold frames.
[0028] refer to Figure 1 and Figure 3As shown, symmetrical fixed seats 13 are fixedly installed on the first mold frame 7. A rotating shaft 14 is rotatably connected between the symmetrical fixed seats 13. A handwheel 23 is rotatably installed on one side of the fixed seat 13. One end of the handwheel 23 passes through the fixed seat 13 and is fixedly connected to the center of one side of the rotating shaft 14. A fixed collar 15 is fixedly sleeved on the rotating shaft 14. A buckle plate 16 is fixedly installed on the fixed collar 15. Springs 26 are fixedly sleeved on the shaft of the rotating shaft 14 on both sides of the fixed collar 15. One end of the spring 26 is fixedly connected to the first mold frame 7, and the other end is fixedly connected to the buckle plate 16.
[0029] It should be noted that rotating the handwheel 23 controls the rotation of the buckle plate 16. When the buckle plate 16 rotates, the springs 26 on both sides are stretched and provide a rebound force in the opposite direction, thereby supporting the buckle plate 16 to be locked on the locking plate 24.
[0030] The working principle of the mold frame closing and locking mechanism provided by this utility model is as follows:
[0031] First, the motor 3 is started to drive the bidirectional screw 4 to rotate, so that the first mold frame 7 and the second mold frame 8 on both sides approach each other and close the mold. After the mold is closed, the cylinders 11 on both sides are started to drive the pressure plates 12 on both sides to press tightly against the mounting pads 9 on one side of the first mold frame 7 and the second mold frame 8, further increasing the stability of the mold closing. Then, the handwheel 23 is turned to drive the buckle plate 16 to rotate. The springs 26 on both sides are stretched and provide a reverse rebound force, thereby supporting the buckle plate 16 to lock onto the locking plate 24. At the same time, the two side locking blocks 21 of the buckle plate 16 will be locked into the symmetrical locking grooves 25, thereby further increasing the locking force. When lubrication is required, the oil pump 18 is started to pump the lubricating oil in the oil tank 17 into the two side locking blocks 21 and finally flow out from several through holes 22 into the locking grooves 25, so that the contact surfaces of the locking grooves 25 and the locking blocks 21 can be lubricated.
[0032] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
[0033] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
