Depending on the needs of factory implementation, guide rails can be set on the working plane to guide the movement of the upright frame, and the maintenance position of the mold top plate can be specified.
[0033] A limiting head is installed on the side end face of the movable seat 3A facing the mold top plate 1; a groove block is provided on the limiting head to cooperate with the protrusion on the side edge of the mold top plate 1.
[0034] The positioning support rod 4 consists of two parallel smooth rods; both ends of the positioning support rod 4 are detachably connected to the upright frame 3, and the middle of the positioning support rod 4 passes through the functional platform 5; a hook for cooperating with the crane is also provided on the top of the functional platform 5.
[0035] For details on the transmission assembly, please refer to [link / reference]. Figure 5 and Figure 6 The transmission assembly 6 includes a bracket 6A disposed on the underside of the functional table 5; at least four sprockets 6B are rotatably mounted on the bracket 6A; a rigid chain 6C is wound around the sprockets 6B; the shape formed by the chain 6C is consistent with the inner frame shape of the split mold frame 2; and a slide 7 is detachably mounted on a unit chain of the chain 6C. In this embodiment, the bracket and the functional table are detachably connected, allowing the operator to replace the bracket structure according to different usage requirements.
[0036] For the specific structure of the support, please refer to Figure 7The bracket 6A includes two opposing horizontal plates 6A1; a parallel longitudinal beam 6A2 is provided between the two horizontal plates 6A1; sprockets 6B are rotatably mounted on the longitudinal beam 6A2; a flat plate 6A3 is also provided on the lower end face of the two horizontal plates 6A1; the sprockets 6B and the chain 6C are located in the area between the flat plate 6A3 and the longitudinal beam 6A2; a main guide groove 6A4 is also provided on the flat plate 6A3; the slide 7 is connected to the chain 6C at the main guide groove 6A4.
[0037] The slide table 7 has a rhomboid cross-section; the center of the back of the slide table 7 is connected to the chain 6C, and a limit rod is also provided on the back of the slide table 7; a secondary guide groove 6A5 is also provided on the plate 6A3, which matches the movable contour line of the limit rod on the slide table.
[0038] There are three limit rods, and the lines connecting the three limit rods can form an isosceles triangle; the point where the slide 7 is connected to the chain 6C is located at the midpoint of the base of the isosceles triangle.
[0039] In this embodiment, the main guide groove and the secondary guide groove are set by dividing the plate. To avoid interference between the slide and the chain connection and the plate component during rotation, the plate is divided into an outer frame irregular plate and an inner irregular plate. The outer frame irregular plate has a rectangular window-like structure in the middle of the plate, and three outer limiting plates are cantilevered on the left, right and bottom sides of the window via connecting rods. It should be noted that the limiting plates and the plate are on the same plane, while the connecting rods are attached to the back of the limiting plates and the plate to avoid interference between the connecting rods and the movement of the limiting rods. There are three longitudinal beams in this embodiment. The inner irregular plate includes a rectangular center plate installed on the middle longitudinal beam via a top rod, and three inner limiting plates are cantilevered on the left, right and top sides of the rectangular center plate via connecting rods. Since the limiting rods on both sides of the slide will intersect with the upper limiting plate during movement, a pair of guide grooves are opened on the front of the upper limiting plate. Both the main guide groove and the secondary guide groove are formed by the outer frame irregular plate, the inner irregular plate, the outer limiting plate and the inner limiting plate.
[0040] The motion profile of the limit rod and the part where the slide connects to the chain can be referenced. Figures 9 to 11 In essence, the motion profile of the section where the slide connects to the chain is a rectangular annular channel around the outer periphery of the inner irregular plate, and there are no interfering objects within this channel. By setting a secondary guide groove that works in conjunction with the main guide groove, the motion posture of the slide is restricted, ensuring the stability of the slide during its circular motion.
[0041] Two identical pulleys 9 are also provided between the first motor and the transmission assembly 6; a transmission belt 10 is fitted between the pulleys 9; the two pulleys 9 are installed at diagonal positions on the sprockets 6B, and the corresponding pulleys 9 and sprockets 6B are coaxial. By setting the pulleys and transmission belt, the two sprockets on the lower side can simultaneously serve as output wheels, making the chain drive more stable and reliable.
[0042] The first motor is powered by an external power source, and the second motor is powered by a battery built into the slide table 7. The cleaning head is a cylindrical stepped structure that is larger at the top and smaller at the bottom, and the height of its lower small diameter end is not less than the depth of the split mold frame 2.
[0043] When using the device in this embodiment, the following process can be referred to:
[0044] First, confirm that all parts of the cleaning device are installed correctly. Then, place the removed mold top plate on the working surface and move the stand so that the groove blocks on both sides of the stand are engaged with the protrusions on the side edges of the mold top plate. When the function table is aligned with the split mold frame, the working height of the function table can be lowered by the hydraulic push rod on the stand. When the turntable approaches the split mold frame, turn on the switch of the second motor to drive the cleaning head to rotate. When the cleaning head is fully in position, turn on the switch of the first motor to allow the first motor to drive the slide to move in accordance with the contour of the annular inner cavity of the split mold frame through the transmission component. The cleaning head will then complete the cleaning work of the split mold frame. After that, the split mold frames can be cleaned one by one as needed.
