[0023] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort should fall within the scope of protection of this utility model.

[0024] A quick mold changing device for a block forming machine includes a base 1. The quick mold changing mechanism described in this utility model is used for quick mold changing of a block forming machine 23. The block forming machine 23 is provided with an upper mold fixing mechanism and a lower mold fixing mechanism. The upper mold fixing mechanism and the lower mold fixing mechanism are respectively used to fix the upper mold and the lower mold of the mold. The lower mold fixing mechanism can adopt multiple airbag pressing structures. The block forming machine 23, the upper mold fixing mechanism and the lower mold fixing mechanism on the block forming machine 23, and the airbag pressing structure on the lower mold fixing mechanism are all existing technologies. The airbag pressing mechanism includes a fixed platform 20 and a rotating arm 21 rotatably mounted on the fixed platform 20. One end of the rotating arm 21 is connected to the top of the airbag 22. During operation, the rotation of the rotating arm 21 is achieved by the inflation and deflation of the airbag 22, thereby realizing the action of pressing and releasing the lower mold. The lower mold of the mold has protrusions on both sides that can be inserted between the fixed platform 20 and the rotating arm 21. The base 1 is installed on one side of the block forming machine 23, and the mold feeding trolley 3 can move into the block forming machine 23. When the mold feeding trolley 3 drives the mold into the block forming machine 23, the two sides of the lower mold will be inserted between the fixed platform 20 and the rotating arm 21. In the block forming machine 23, the lower mold fixing mechanism can be driven to rise and fall by the lifting mechanism on the block forming machine 23. When the two sides of the lower mold enter between the fixed platform 20 and the rotating arm 21, when the lower mold fixing mechanism is driven to rise by the lifting mechanism on the block forming machine 23, since the protrusion of the lower mold is on the upper side of the fixed platform 20, the fixed platform 20 will simultaneously drive the lower mold and the upper mold to move upward. The rotating arm 21 can be rotated by the inflation of the air bag 22 and the protrusion of the lower mold can be pressed down, thereby fixing the lower mold. At the same time, the upper mold will move to a fixed position and be fixed by the upper mold fixing mechanism on the block forming machine 23.

[0025] A lifting seat 2 is installed on the upper side of the base 1. The lifting seat 2 is driven to move up and down by a longitudinal drive assembly. The longitudinal drive assembly includes front and rear cylinders 6 located on the right side of the base 1. The bottom of the cylinders 6 is rotatably mounted on a support seat 7. The piston rod of the cylinders 6 is rotatably connected to the right end of the lifting seat 2. Multiple cranks 8 are installed between the lifting seat 2 and the base 1. The upper and lower ends of the cranks 8 are rotatably connected to the lifting seat 2 and the base 1, respectively.

[0026] When the lifting seat 2 rises, the two hydraulic cylinders 6 simultaneously drive the lifting seat 2 upward via piston rods. During this upward movement, the crank 8 between the lifting seat 2 and the base 1 rotates, changing its inclination. Similarly, when the lifting seat 2 needs to descend, the two hydraulic cylinders 6 simultaneously drive the lifting seat 2 downward via piston rods. During this downward movement, the crank 8 between the lifting seat 2 and the base 1 rotates. The lifting seat 2 is supported by the crank 8 and the hydraulic cylinders 6.

[0027] Two cranks 8 are respectively installed on the front and rear sides between the lifting seat 2 and the base 1. This utility model has a total of four cranks 8, that is, two cranks 8 are provided on the front and two on the rear. Of course, we can also design more cranks 8 for support as needed.

[0028] The top of the lifting seat 2 is slidably mounted with a mold feeding trolley 3. The mold feeding trolley 3 is driven to move left and right laterally by a lateral drive component. The mold feeding trolley 3 can be moved into the block forming machine 23 for mold changing by the lateral drive component.

[0029] The lateral drive assembly includes a motor 11 and left and right drive shafts 12. The drive shafts 12 are rotatably mounted on bearing seats 13. Drive sprockets 14 are mounted on the front and rear sides of each drive shaft 12. Drive chains 15 are fitted onto the corresponding drive sprockets 14 on each drive shaft 12. The drive chains 15 on both sides are fixedly connected to the mold feeding carriage 3. One of the drive shafts 12 is connected to the motor 11 via a transmission connection. When the lateral drive assembly is in operation, the motor 11 first drives one drive shaft 12 to rotate. This drive shaft 12 then drives the other drive shaft 12 to rotate via the drive chains 15 on both sides. During rotation, the drive chains 15 on both sides simultaneously drive the mold feeding carriage 3 to move laterally.

[0030] A driven sprocket 16 is fixedly connected to the drive shaft 12 which is connected to the motor 11. An active sprocket 17 is installed on the output shaft of the motor 11. The active sprocket 17 and the driven sprocket 16 are connected by a chain.

[0031] Vertical rods 18 extending downwards are installed on the front and rear sides of the right end of the mold feeding trolley 3, and the drive chains 15 on both sides are fixedly connected to the vertical rods 18 on both sides. A crossbar 19 is installed between the vertical rods 18 on the front and rear sides of the mold feeding trolley 3, and the drive chains 15 on both sides are fixedly connected to the vertical rods 18 on both sides through the crossbar 19. Two vertical rods 18 extending downwards are installed on the front and rear sides of the right end of the mold feeding trolley 3, and a crossbar 19 is installed between the two front vertical rods 18 and the corresponding rear vertical rods 18, and the two ends of the drive chains 15 are fixedly connected to the crossbars 19 on both sides.

[0032] This invention features four vertical rods 18. Two vertical rods 18 are installed on the front and two on the rear of the mold feeding trolley 3. Two horizontal rods 19 are installed between the front vertical rod 18 and the corresponding rear vertical rod 18. The two ends of the drive chain 15 are connected to the two horizontal rods 19, thus connecting the drive chain 15 to the vertical rods 18. By setting the vertical rods 18, this invention creates an L-shaped structure for the mold feeding trolley 3, allowing the left end of the mold feeding trolley 3 to be inserted into the block forming machine 23.

[0033] Multiple positioning pins 4 are fixedly installed on the top of the mold feeding trolley 3. Two positioning pins 4 are installed on the front and rear sides of the top of the mold feeding trolley 3 respectively. This utility model has a total of four positioning pins 4, which are used for positioning and fixing the mold.

[0034] The base 1 is supported by the legs 5.

[0035] The lifting seat 2 has guide rails 9 installed on its front and rear sides, and the bottom of the mold feeding trolley 3 is equipped with rollers 10 that cooperate with the guide rails 9 on both sides. The mold feeding trolley 3 of this invention moves back and forth along the guide rails 9 via the rollers 10.

[0036] The working process of this utility model:

[0037] In this invention, when changing the mold, the mold on the block forming machine 23 must first be disassembled. During disassembly, the lifting seat 2 and the mold feeding trolley 3 are first moved upwards by the hydraulic cylinders 6 on both sides. Then, the motor 11 is started, and the motor 11 drives the mold feeding trolley 3 along the guide rail 9 on the top of the lifting seat 2 towards the block forming machine 23 via the drive chains 15 on both sides. The mold feeding trolley 3 is moved into the block forming machine 23 until it is inside. Then, the upper mold fixing mechanism and the lower mold fixing mechanism of the block forming machine 23 are released from fixing the upper and lower molds respectively. The lower mold fixing mechanism is lowered by operating the lifting mechanism on the block forming machine 23, so that the mold falls onto the mold feeding trolley 3. At this time, the positioning pin 4 on the top of the mold feeding trolley 3 will be inserted into the positioning hole on the fallen mold. Finally, the motor 11 drives the mold feeding trolley 3 away from the block forming machine 23, so that the mold is removed from the block forming machine. 23; When it is necessary to install the mold, first place the mold on the mold feeding trolley 3 and insert the positioning pin 4 into the positioning hole of the mold. Then, drive the lifting seat 2 and the mold feeding trolley 3 to move upward a certain height through the two side cylinders 6. Then, move the mold feeding trolley 3 to the lower mold fixing position inside the block molding machine 23 through the motor 11. During the movement towards the block molding machine 23, the protrusions on both sides of the lower mold will be inserted between the fixed platform 20 and the rotating arm 21 of the airbag compression molding structure. Then, drive the lower mold fixing mechanism to rise through the lifting mechanism on the block molding machine 23. At this time, since the protrusions of the lower mold are on the upper side of the fixed platform 20, the fixed platform 20 will simultaneously drive the lower mold and the upper mold to move upward. Then, the upper mold fixing mechanism and the lower mold fixing mechanism on the block molding machine 23 will fix the upper mold and the lower mold. Finally, drive the mold feeding trolley 3 to move out of the block molding machine 23 through the motor 11.
