Description

Technical Field

[0002] In the production of refractory bricks, the mold used to press refractory bricks needs to be clamped and fixed with a mold frame. Most of the existing mold frames are fixed and can only be used for molds of the same specifications. The mold frame height and space size are fixed length dimensions, so it cannot be used for molds of different specifications. The scope of application is small and it is not convenient to use. The mold frame needs to be replaced when using different molds. The existing clamping and fixing mold method is to fix the mold frame first, and then insert the pad and the inclined iron into the gap between the mold and the mold frame.

The sleeve rod 4420 moves forward under the action of the connecting block 4410, and the push rod 4430 drives the abutment 4450 to move. When the abutment 4450 contacts the first mold frame 3100 head-on, because the push rod 4430 can move in the sleeve rod 4420, the first low joint will retreat, the first spring 4440 is compressed, and the cylinder 4200 continues to work, and the abutment 4450 pushes the first mold frame 3100 to move forward and contacts the fixed second mold frame 3100. The second mold frame 3200 cooperates to clamp the mold body 1000. At the same time, the connecting block 4410 moves forward, driving the connecting rod 4530 to move forward. Since both ends of the connecting rod 4530 are hinged, the connecting rod 4530 can rotate without restriction. The connecting block 4410 will drive the long slider 4520 to move forward in the slide rail sleeve 4510. The long slider 4520 drives the mounting block 4540 to move obliquely forward. The clamping block 4550 also moves obliquely forward under the drive of the mounting block 4540. When the clamping head 4553 of the clamping block 4550 contacts the side of the first mold frame 3100, since the inclined section 4551 and the vertical section 4552 of the clamping block 4550 are hinged to the mounting hole and the oblique section and the mounting block 4540 are connected with a second spring, the second spring is stretched.The clamping head 4553 pushes the first mold frame 3100 to move toward the second mold frame 3200 from the side. When clamping, the second spring is further stretched, and the clamping head 4553 is pressed against the side of the first mold frame 3100 by the spring force. At this time, the first mold frame 3100 and the second mold frame 3200 have clamped the mold, and then the first limit pin 3119 is hammered into the first limit hole, and the second limit pin 31110 is hammered into the second limit hole, completing the fixing of the mold by the first mold frame 3100 and the second mold frame 3200.

[0031] In an embodiment provided by the present invention, preferably, a limit strip 4521 is provided at one end of the long slider 4520 away from the push rod 4300 , and the limit strip 4521 is used to prevent the long slider 4520 from sliding out of the slide rail sleeve 4510 .

[0032] Working principle: according to the height of the mold body 1000, the first mold frame 3100 and the second mold frame 3200 are plugged in, and the first mold frame strips 3110 that meet the required number are plugged into the first mold frame 3100 through the cooperation of the plug strips 31114 and the slots 31113, and the second mold frame strips 3210 that meet the required number are plugged into the second mold frame 3200 through the cooperation of the plug strips 31114 and the slots 31113, and then the first mold frame 3100 and the second mold frame 3200 are plugged in, that is, the first adjustable plug-in section 31112 of the first mold frame strip 3110 is matched with the second adjustable plug-in section 31121 of the second mold frame strip 3210, and the first adjustable plug-in section 31112 of the second mold frame strip 3210 is connected to the second adjustable plug-in section 31113 of the first mold frame strip 3110.

The limiting bolt 3114 is long enough to be suitable for the first mold frame 3100 and the second mold frame 3200 of different heights. Then the positioning pin 3116 is hammered into the positioning hole 3115, and then the first mold frame 3100 and the second mold frame 3200 are moved as a whole so that the right angle of the second mold frame 3200 is matched and engaged with the right angle limiting block 2100, and the mold body 1000 is placed in the space surrounded by the first mold frame 3100 and the second mold frame 3200, and the mold body 1000 is fitted with the inner right angle of the second mold frame 3200, and then the cylinder 4200 is started, and the cylinder 4200 drives The push rod 4300 moves, and the push rod 4300 drives the connecting block 4410 to move. The sleeve rod 4420 moves forward under the action of the connecting block 4410, and the push rod 4430 drives the abutment joint 4450 to move. When the abutment joint 4450 contacts the first mold frame 3100 head-on, because the push rod 4430 can move in the sleeve rod 4420, the first low joint will retreat, the first spring 4440 is compressed, and the cylinder 4200 continues to work. The abutment joint 4450 pushes the first mold frame 3100 to move forward, and cooperates with the fixed second mold frame 3200 to clamp the mold body 1000. At the same time, the connecting block 4410 moves forward, driving the connecting rod 4530 to move forward. Because both ends of the connecting rod 4530 are hinged, the connecting rod 4530 can rotate without restriction. The connecting block 4410 will drive the long slider 4520 to move forward in the slide rail sleeve 4510, and the long slider 4520 will drive the mounting block 4540 to move obliquely forward. The clamping block 4550 will also move obliquely forward driven by the mounting block 4540. When the clamping head 4553 of the clamping block 4550 contacts the side of the first mold frame 3100, since the inclined section 4551 and the vertical section 4552 of the clamping block 4550 are hinged to the mounting hole and the oblique section and the mounting block 4540 are connected with a second spring, the second spring is stretched, and the clamping head 4553 pushes the first mold frame 3100 from the side to move toward the second mold frame 3200. When clamping, the second spring is further stretched, and the clamping head 4553 is pressed against the side of the first mold frame 3100 through the spring elastic force. At this time,The first mold frame 3100 and the second mold frame 3200 have already clamped the mold, and finally the first limit pin 3119 is hammered into the first limit hole, and the second limit pin 31110 is hammered into the second limit hole, completing the fixation of the mold by the first mold frame 3100 and the second mold frame 3200. According to the on-site situation, the mold can be pressed on the mold placement platform 2000 or the mold frame body 3000 and the mold body 1000 can be moved as a whole to the pressing equipment for pressing.

[0033] The above description is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
