[0050] like Figures 3 to 5As shown, the connecting assembly 7 includes a U-shaped plate 71, the opening width of the U-shaped plate 71 is equal to twice the thickness of the connecting plate 4, and the U-shaped plate 71 is clamped on the two connecting plates 4 of the upper and lower cast iron integrated upper frame structures that are close together, and the top and bottom of the U-shaped plate 71 are symmetrically penetrated with plug holes that match the size of the connecting hole 5, and the plug holes are plugged with a latch assembly 8, and the side of the U-shaped plate 71 is rotatably penetrated and plugged with a first screw rod 72, and the part of the first screw rod 72 located on the inner side of the U-shaped plate 71 is threadedly sleeved with an extrusion block 73, and the thickness of the extrusion block 73 matches the height of the inner side of the U-shaped plate 71, and the front and rear ends of the extrusion block 73 are both inclined, and the inclined surfaces of the front and rear ends of the extrusion block 73 are parallel to and fit with the inclined surface on the opposite side of the connecting block 6;

[0051] The latch assembly 8 includes a fixing pin 81, which is inserted between the top and bottom insertion holes of the U-shaped plate 71, and both ends of the fixing pin 81 are fixedly connected with baffles 82 matching the inner diameter of the insertion hole. The middle part of the fixing pin 81 is slidably sleeved with a clamping sleeve 83, and the length of the clamping sleeve 83 is greater than twice the thickness of the connecting plate 4. The clamping sleeve 83 includes conical portions 831 at both ends and a cylindrical portion 832 in the middle. The diameters of the two conical portions 831 gradually increase in the direction away from each other, and the maximum diameter of the conical portion 831 is equal to the diameter of the baffle 82. The two connecting plates 4 located on the inner side of the U-shaped plate 71 The connecting hole 5 on the top and the positions relative to the two conical parts 831 are all designed with conical surfaces, and the conical surface of the connecting hole 5 is parallel to the conical surface of the conical part 831 and fits together. The length of the cylindrical part 832 is less than twice the thickness of the connecting plate 4. The top of the baffle 82 located at the top and the end of the first screw 72 located outside the U-shaped plate 71 are fixedly connected with polygonal protrusions 84 of the same size. The bottom center of the baffle 82 located at the bottom is vertically threaded with a fixing screw 85. The bottom end of the fixing screw 85 is fixedly connected with a U-shaped fixing plate 86, and the fixing plate 86 is fixedly connected to the bottom of the U-shaped plate 71.

[0052] During the use of the cast iron integrated upper frame structure, multiple cast iron integrated upper frame structures can be connected together using the connecting assembly 7 as needed, thereby increasing the shaping area of ​​the cast iron integrated upper frame structure on the stone plastic box board. When using the connecting assembly 7, the multiple cast iron integrated upper frame structures to be connected are first stacked together from top to bottom in sequence, and the two ends of the multiple cast iron integrated upper frame structures are kept flush, and then the U-shaped plate 71 is inserted from the side into the two connecting plates 4 of the upper and lower adjacent cast iron integrated upper frame structures that are close to each other, and at this time, the four connecting blocks 6 close to the current two connecting plates 4 are also located together in the inner area of ​​the U-shaped plate 71, and then the position of the U-shaped plate 71 is adjusted to align the jack on the U-shaped plate 71 with the connecting holes 5 on the two inner connecting plates 4;

[0053] Then, the fixing pin 81 is inserted into the aligned connecting hole 5 and the baffle 82 at the bottom of the fixing pin 81 is inserted into the fixing screw 85. Then, the polygonal protrusion 84 at the top of the fixing pin 81 is screwed with a socket wrench, so that the fixing pin 81 can be screwed together with the fixing screw 85, thereby achieving simple fixation of the fixing pin 81. Then, the first screw 72 is screwed with the socket wrench. As the first screw 72 is screwed, the extrusion block 73 can move toward the direction close to the connecting block 6 under the action of the first screw 72. When the inclined surfaces at both ends of the extrusion block 73 contact the inclined surfaces of the connecting block 6, as the first screw 72 continues to rotate, the extrusion block 73 begins to pull the U-shaped plate 71 away from the connecting plate 4 through the first screw 72 due to the obstruction of the connecting block 6. As the U-shaped plate 71 moves, the fixing pin 81 The clamping sleeve 83 on the upper part is also gradually contacted with the inner wall of the connecting hole 5 on the two connecting plates 4 under the pulling of the U-shaped plate 71. In this process, the two conical parts 831 on the clamping sleeve 83 can apply pressure to the two connecting plates 4 in the direction of approaching each other through the conical surface parts of the connecting holes 5 on the two connecting plates 4, so that the two cast iron integral upper frame joints can be tightly fitted together under the action of this pressure. In addition, as the clamping sleeve 83 is gradually clamped with the inner wall of the connecting hole 5, the two ends of the extrusion block 73 are also squeezed together with the opposite inclined surface of the connecting block 6. At this time, the inclined surface at the end of the extrusion block 73 can limit the inclined surface of the connecting block 6, so that the front and rear sides of the two cast iron integral upper frame joints can be kept in the same plane, thereby realizing the alignment of the two cast iron integral upper frame joints while realizing the tight connection between the two cast iron integral upper frame joints;

[0054] Compared with the existing method of connecting with bolts, since the fixing pin 81 and the second screw rod 9 in the present invention are not directly threadedly connected to the cast iron integrated frame structure, it also avoids the situation in which the bolts and the cast iron integrated frame structure are corroded together due to the rust of the bolts during the long-term use of the cast iron integrated frame structure. In addition, when connecting two cast iron integrated frame structures, only two connecting components 7 are needed to connect the two ends of the two cast iron integrated frame structures, thereby improving the convenience and speed of disassembly.

[0055] like Figure 6As shown, a second screw rod 9 is rotatably inserted between the centers of circles at both ends of the first screw rod 72, and a movable column 10 is threadedly sleeved on one end of the second screw rod 9 located on the inner side of the U-shaped plate 71. The movable column 10 is slidably inserted in the end of the first screw rod 72 located on the inner side of the U-shaped plate 71 along the axial direction of the second screw rod 9, and a cross-shaped slot is provided on the end of the second screw rod 9 located on the outer side of the U-shaped plate 71, and a movable sleeve 12 is slidably sleeved on the free end of the movable column 10, and a limiting column 13 is fixedly connected to the axis center of the movable sleeve 12 on the side opposite to the free end of the movable column 10, and a shock-absorbing spring 14 is sleeved on the periphery of the limiting column 13, and the two ends of the shock-absorbing spring 14 are respectively fixedly connected to the movable sleeve 12 and the movable column 10;

[0056] When the two ends of the extrusion block 73 are pressed together with the four connecting blocks 6 on the inner side of the U-shaped plate 71, although the connecting assembly 7 realizes the basic connection operation of the two cast iron integrated frame structures through the cooperation of the extrusion block 73 and the connecting block 6 and the cooperation of the latch assembly 8 and the connecting plate 4, since the end of the first screw 72 located on the inner side of the U-shaped plate 71 is still not in a suspended state, the two cast iron integrated frame structures may shake due to mechanical vibration during the use of the cast iron integrated frame structure. At this time, by providing the second screw 9, when the first screw 72 is fully tightened, the second screw 9 can be screwed with a screwdriver, and as the second screw 9 rotates, the movable column 10 can drive the movable sleeve 12 to gradually move towards the direction close to the connecting plate 4 under the action of the second screw 9. The movable sleeve 12 gradually approaches the two connecting plates 4 on the inner side of the U-shaped plate 71. When the movable sleeve 12 contacts the two connecting plates 4, as the second screw rod 9 continues to rotate, the movable sleeve 12 can stop moving under the obstruction of the connecting plates 4 and gradually compress the shock-absorbing spring 14. As the shock-absorbing spring 14 is gradually compressed, the limiting column 13 gradually approaches the end of the movable column 10. When the limiting column 13 contacts and presses the movable column 10, the shock-absorbing spring 14 stops being compressed, and the movable sleeve 12 is tightly pressed together with the connecting plate 4, so that the end of the first screw rod 72 located on the inner side of the U-shaped plate 71 can establish a stable connection relationship with the connecting plate 4 through the movable sleeve 12 and the movable column 10, thereby improving the stability of the connection assembly 7 as a whole for the connection between the two cast iron integrated upper frame structures.

[0057] In addition, due to the presence of the shock-absorbing spring 14, during the use of the two cast iron integrated frame structures, when mechanical vibration is transmitted to the movable sleeve 12 through the connecting plate 4, the shock-absorbing spring 14 located on the inner side of the movable sleeve 12 can absorb the vibration, thereby preventing the second screw 9 from loosening under the action of mechanical vibration.

[0058] like Figure 5As shown, the fixing pin 81 is sleeved with a centering spring 11 near both ends, and both ends of the centering spring 11 are fixedly connected to the baffle 82 and the conical portion 831 of the clamping sleeve 83 respectively;

[0059] By providing a centering spring 11, in the initial state, the two centering springs 11 can simultaneously apply a thrust to the sleeve 83, so that the sleeve 83 can be centrally sleeved on the fixing pin 81, and then when the sleeve 83 contacts the two connecting plates 4 on the inner side of the U-shaped plate 71, the two conical portions 831 of the sleeve 83 can evenly apply pressure to the conical surface portions of the connecting holes 5 of the two connecting plates 4.

[0060] like Figure 6 As shown, one end of the movable sleeve 12 away from the first screw rod 72 is fixedly connected to a plurality of anti-sliding blocks 15, and the plurality of anti-sliding blocks 15 are distributed in a ring shape;

[0061] By providing the anti-sliding block 15 , when the movable sleeve 12 and the two connecting plates 4 inside the U-shaped plate 71 are pressed together, the anti-sliding block 15 can ensure that the movable sleeve 12 and the connecting plates 4 will not rotate relative to each other due to vibration.

[0062] The present invention also provides a manufacturing process for a cast iron integrated upper frame structure of a stone plastic box plate shaping platform, the process comprising the following steps:

[0063] Step 1: Add the cast iron required for casting the cast iron integrated upper frame structure into the furnace for melting;

[0064] Step 2: Heat the mold used for casting, and after the mold is heated, pour the molten cast iron solution into the mold;

[0065] Step 3: After the mold and the cast iron integrated upper frame structure are completely cooled, the cast iron integrated upper frame structure is taken out and placed in a furnace for annealing;

[0066] Step 4: After the annealing of the cast iron integrated upper frame structure is completed, use a grinding tool to grind and polish the burrs on the edges and corners of the cast iron integrated upper frame structure;

[0067] Step 5: Apply high temperature resistant anti-rust paint on the non-working surface of the cast iron integrated upper frame structure after grinding and polishing.

[0068] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
