[0043] According to the above structural features of the present application, the embodiments of the present application are further described:

[0044] The prefabricated mold of the track plate 6 includes a bottom mold 5 and a side mold 4, and the side mold 4 is arranged on the upper surface of the bottom mold 5. The side mold 4 is provided with four parts and surrounds a rectangular shape, thereby forming a plate-shaped cavity in the middle. The user arranges a steel cage in the cavity and pours concrete. After the concrete hardens, the mold is removed to obtain the track plate 6 product.

[0045] Referring to Figures 1-2 , the present embodiment provides an automatic mold opening and closing driving module of a track plate prefabricated mold, which includes a support assembly 1 fixedly connected to the side wall of the bottom mold 5 and a sliding assembly 2 fixedly connected to the bottom surface of the side mold 4. The sliding assembly 2 is press-connected to the support assembly 1 and can slide, thereby carrying the side mold 4 to move towards the direction of approaching or moving away from the cavity, realizing mold closing and mold opening.

[0046] Referring to Figures 2-4 , the support assembly 1 comprises a slide plate 11 and a pulley 12; the cross section of the slide plate 11 is U-shaped and opens upward. The pulley 12 is arranged in the inner cavity of the slide plate 11 through a rotating shaft, and the pulley 12 can freely rotate around the rotating shaft. The pulley 12 is provided with a plurality of pulleys and is arranged at equal intervals along the length direction of the slide plate 11;

[0047] Referring to Figures 2-5 , the sliding assembly 2 comprises a sliding column 21 and a connecting block 22. The cross section of the sliding column 21 is circular or annular, so as to have excellent bearing capacity to avoid deformation under pressure. The sliding column 21 is transversely arranged and selectively press-fitted on the pulley 12, and the sliding column 21 can reciprocally slide along the length direction of the slide plate 11. The connecting block 22 is connected with the sliding column 21 at the bottom surface (for example, through bolted connection or through integrated fixed connection) and connected with the side mold 4 at the top surface (for example, through bolted connection or through welded fixed connection), so that the sliding column 21, the connecting block 22 and the side mold 4 can synchronously slide along the length direction of the slide plate 11; the slide plate 11 is arranged perpendicularly to the side wall of the bottom mold 5, and the sliding column 21 is arranged perpendicularly to the side mold 4, so that the sliding column 21, the connecting block 22 and the side mold 4 can synchronously move to approach or move away from the cavity, thereby realizing mold closing and mold opening.

[0048] The pulley 12 is a fixed pulley. The pulley 12 is used to reduce the friction between the support assembly 1 and the sliding assembly 2, and increase the sliding smoothness of the sliding column 21 and the side mold 4.

[0049] Referring to Figure 2 , Figure 3 and Figure 5 , the bottom end of the sliding column 21 is arranged in the inner cavity of the slide plate 11, and the middle part and the top end of the sliding column 21 are arranged above the slide plate 11, so that when the side mold 4 is close to the inner boundary of the movable range, the end surface of the sliding column 21 abuts against the position of the side wall of the bottom mold 5, avoiding the problem that the sliding column 21 is inserted into the first insertion slot 52 to cause jamming. The middle part of the circumferential surface of the pulley 12 is provided with a press-fitting groove, and the bottom end of the sliding column 21 is press-fitted and limited in the press-fitting groove. Under the action of gravity, the sliding column 21 is arranged in the middle position of the press-fitting groove to avoid eccentric loading. When the sliding column 21 is eccentrically loaded, it will extrude the slide plate 11 from inside to outside, increase the sliding resistance, and make the top of the side wall of the slide plate 11 outwardly open to cause the pulley 12 to fall off, which will further damage the linear driver 31 and even cause a safety accident.

[0050] Referring to Figure 2 , the slide plate 11 is horizontally arranged; the bottom mold 5 is provided with a first insertion slot 52, and one end of the slide plate 11 is inserted into the first insertion slot 52 and fixedly connected (for example, through bolted connection); the pulley 12 is arranged at the position of the other end of the slide plate 11.

[0051] Referring to Figure 4 and Figure 5The slide plate 11 includes a base plate 112, side plates 111, and an inner support plate 113. The base plate 112 is horizontal, and the side plates 111 are vertical. There are two side plates 111, which are respectively fixedly connected to the two side edges of the base plate 112 perpendicularly (e.g., by welding, bolting, or integral connection). The inner support plate 113 is placed between the two side plates 111, and the side edges of the inner support plate 113 are fixedly connected to the side plates 111 perpendicularly (e.g., by welding), and the bottom edge of the inner support plate 113 is fixedly connected to the base plate 112 perpendicularly (e.g., by welding). The inner support plate 113 is used to apply supporting force and / or tensile force to the side plates 111, thereby ensuring the parallelism between the two side plates 111 and preventing the top of the side plates 111 from flipping inward or outward and deforming. The inner support plate 113 is placed in the first insertion groove 52 to increase the structural strength of the pressing position between the slide plate 11 and the first insertion groove 52, thereby preventing the slide plate 11 from deforming and improving the load-bearing capacity of this utility model.

[0052] Reference Figure 6 and Figure 7 The present invention also includes a drive assembly 3, which is connected at both ends to the bottom mold 5 and the side mold 4, respectively.

[0054] Reference Figure 6 and Figure 7 The extension 32 includes an abutment plate 321 and a back support plate 322, both of which are vertically positioned. The abutment plate 321 and the back support plate 322 are vertically fixedly connected (e.g., by welding or by an integral connection). The output shaft is connected to the abutment plate 321 (e.g., by bolts). The output shaft and the back support plate 322 are located on opposite sides of the abutment plate 321. The back support plate 322 applies a supporting force to the abutment plate 321 towards the output shaft, preventing the abutment plate 321 from bending or deforming. The top ends of both the abutment plate 321 and the back support plate 322 are fixedly connected to the bottom surface of the side mold 4 (e.g., by welding or by bolts).

[0055] Reference Figure 8 and Figure 9The extension block 41 is connected with the side mold 4 (for example, fixed connection or fixed connection by welding), and the positioning groove 61 is used for convenient positioning when the track plate 6 is constructed on site. The extension block 41 is pressed on the upper surface of the bottom mold 5 and is in sliding connection, the extension block 41 moves synchronously with the side mold 4, so that the mold opening and closing of the side mold 4 are adapted. The linear driver 31 is arranged below the extension block 41, so that dust, concrete mortar and other impurities are prevented from falling on the output shaft, further preventing the output shaft and the inner cavity of the linear driver 31 from being worn by impurities, preventing the output shaft from being stuck, and prolonging the service life of the utility model.

[0056] Referring to Figure 8 The middle part of the side mold 4 is supported by the extension block 41. Referring to Figures 6-8 The bottom surface of the single side mold 4 is provided with two sliding assemblies 2, and the two sliding assemblies 2 are respectively arranged on the two sides of the extension block 41; the single side mold 4 needs to be supported by two supporting assemblies 1, and the two sliding assemblies 2 are respectively pressed on the two supporting assemblies 1, so as to realize stable support of the side mold 4. Referring to Figure 6 The single side mold 4 needs to be driven by at least one driving assembly 3, and the driving assembly 3 is located below the extension block 41, that is, the two sliding assemblies 2 are respectively arranged on the two sides of the driving assembly 3, so as to realize smooth and smooth driving.

[0057] The supporting assembly 1, the sliding assembly 2 and the linear driver 31 are arranged in parallel with each other, so as to improve the moving fluency of the side mold 4.

[0058] Referring to Figure 10 The bottom surface of the bottom mold 5 is provided with a supporting leg 51, the supporting leg 51 is vertically arranged, and the top end of the supporting leg 51 is fixedly connected with the bottom mold 5 (for example, fixed connection by bolts or fixed connection by welding). The inclined support rod 511 is connected between the slide plate 11 and the supporting leg 51 to form a triangular structure. The top end of the inclined support rod 511 is fixedly connected with the bottom plate 112 of the slide plate 11 (for example, fixed connection by welding or fixed connection by bolts), and the bottom end of the inclined support rod 511 is fixedly connected with the side wall of the supporting leg 51 (for example, fixed connection by welding or fixed connection by bolts). The inclined support rod 511 is used for supporting the slide plate 11, avoiding the bending of the slide plate 11 under pressure, thereby increasing the carrying capacity and functional reliability of the utility model.

[0059] After the mold is opened, although the track plate 6 has a certain distance from the side mold 4, when the track plate 6 is lifted by the sling and hook of the roof traveling crane, transverse shaking is inevitable, and the shaking track plate 6 will hit the side mold 4 and damage the linear driver 31. In order to avoid such problems: referring to Figure 11The edge position of the top surface of the bottom die 5 is provided with a limiting insertion hole in a vertical position; after the mold is opened, a user takes the limiting insertion rod 7 in a vertical position and inserts the limiting insertion rod 7 into the limiting insertion hole, so that the track plate 6 can be lifted without colliding with the side die 4 (the track plate 6 will collide with the limiting insertion rod 7 when the track plate 6 shakes), thereby protecting the side die 4 and the linear driver 31 and improving the service life of the utility model.

[0060] The diameter of the bottom end of the limiting insertion rod 7 is adapted to the diameter of the limiting insertion hole, so that the limiting insertion rod 7 can be conveniently and smoothly inserted into or pulled out of the limiting insertion hole.
