[0027] Among them, as Figure 1 、 Figure 3 And Figure 4As shown, the translation mechanism includes a sliding support rod 21 fixedly connected to the top end of the support rod 2, which provides a horizontal sliding track for the sleeve 29, and the clamping blocks at both ends can prevent the tray 22 or the sleeve 29 from falling out. The sliding sleeve 29 is sleeved on the sliding support rod 21, the outer wall of the sleeve 29 is fixedly connected with the tray 22, the upper surface of the tray 22 is fixedly connected with the first motor 24, and the output shaft of the first motor 24 drives the U-shaped groove pulley 25 to rotate, providing power for the horizontal movement of the translation mechanism. The tray 22 is also fixedly connected with an oval block 23, and the oval block 23 is rotatably connected with a pair of U-shaped groove pulleys 25 clamping the sliding support rod 21. The U-shaped groove pulley 25 clamps the sliding support rod 21, cooperates with the first motor 24 to drive the tray 22 to move horizontally along the sliding support rod 21, and the groove surface of the U-shaped groove pulley 25 is provided with an annular tooth pattern; the outer wall of the sliding support rod 21 is provided with an axial tooth pattern matched with the annular tooth pattern, and the two are matched and frictionally transmitted through the tooth pattern engagement, forming a mechanical engagement limiting structure, which effectively prevents the sliding support rod 21 from slipping relative to the U-shaped groove pulley 25. The output shaft of the first motor 24 is movably penetrated through the oval block 23 and fixedly connected with one end of one of the U-shaped groove pulleys 25, and the two ends of the sliding support rod 21 are fixedly connected with clamping blocks for clamping the tray 22 or the sleeve 29 to prevent them from falling out of the sliding support rod 21.

[0028] In addition, as shown in Figure 1 and Figure 4 , the lifting mechanism includes a second motor 26 fixedly connected to the tray 22, and the output shaft of the second motor 26 drives the gear 27 to rotate, providing power for the up-down movement of the lifting mechanism. The output shaft of the second motor 26 is fixedly connected with the gear 27, and the gear 27 is engaged with the rack 3 to convert the rotary power of the second motor 26 into the linear movement power of the rack 3. A sliding groove 28 is formed in the tray 22, and a rack 3 engaged with the gear 27 is slidably connected inside the sliding groove 28. The top end of the rack 3 is fixedly connected with a protrusion for clamping the sliding groove 28, and the inside of the sliding groove 28 is provided with a plurality of first balls 201 in contact with the rack 3 to reduce the friction resistance of the rack 3 when sliding in the sliding groove 28, improving the sliding smoothness. The first balls 201 are in contact with the rack 3, the inside of the sleeve 29 is provided with a plurality of second balls 202 in contact with the outer wall of the sliding support rod 21, the second balls 202 are in contact with the outer wall of the sliding support rod 21 to reduce the sliding friction between the sleeve 29 and the sliding support rod 21, and the operation of the translation mechanism is smooth. The first balls 201 and the second balls 202 are evenly installed on the retainer in the channel of the sliding groove 28 and the sleeve 29, the ball retainer is used to limit the circumferential distance of the balls to avoid mutual contact and friction to reduce wear and running noise, guide the balls to roll along the preset track, ensure the stability and precision of transmission or guidance, and prevent the balls from falling off.

[0029] It is worth noting that, as shown in Figure 1 andFigure 3 As shown, the suction mechanism includes a drop plate 31 fixedly connected to the bottom end of the rack 3. A cylinder 32 is fixedly connected to the drop plate 31. The cylinder 32 drives the vacuum suction cup 34 to approach or move away from the building block, realizing the suction and release action. The rack 3 is also provided with an alignment plate 33 for aligning the shaped building block. The alignment plate 33 is provided with multiple vacuum suction cups 34 that align with and hold individual shaped building blocks. The alignment plate 33 supports multiple vacuum suction cups 34 to ensure that the vacuum suction cups 34 are accurately aligned with the shaped building block and the alignment port 42 on the docking plate 41. The piston rod of the cylinder 32 moves through the drop plate 31 and is fixedly connected to the middle of the alignment plate 33. The vacuum suction cup 34 is made of highly elastic silicone with good sealing properties. It is connected to the suction mechanism, which works based on the principle of negative pressure adsorption. Its structure includes an air source (vacuum pump or negative pressure generator), an air passage connecting the air source and the vacuum suction cup 34, and the vacuum suction cup 34 body. The air source generates negative pressure, which is transmitted to the vacuum suction cup 34 through the air path. The vacuum suction cup 34 adheres to the surface of the workpiece to form a sealed cavity, and the pressure difference between the inside and outside of the cavity generates suction. The silicone material is elastic and can be adapted to different curved surfaces, enhancing the sealing performance and adsorption stability.

[0030] Furthermore, such as Figures 2 to 3 As shown, the sorting mechanism includes a support plate 4 fixedly connected to the outer wall of one of the support rods 2. A docking plate 41 corresponding to the alignment disc 33 is fixedly connected to the support plate 4. Alignment ports 42 on the docking plate 41 provide a guiding channel for the building blocks, ensuring accurate entry of the building blocks into the sorting conduit 43. Multiple alignment ports 42 corresponding to vacuum suction cups 34 are provided on the docking plate 41, guiding the adsorbed building blocks into the corresponding sorting conduit 43. Multiple sorting conduits 43 corresponding to the alignment ports 42 are fixedly connected to the docking plate 41, providing a falling channel for the building blocks and guiding them towards the corrugated hose 44. A corrugated hose 44, whose end is inserted into the corresponding sorting bin 12, is fixedly connected to the bottom of each sorting conduit 43. The corrugated hose 44 guides the building blocks smoothly into the sorting bin 12, achieving precise sorting and storage.

[0031] Furthermore, such as Figure 1 and Figure 3 As shown, the sorting mechanism also includes a tray 11 fixedly connected to the side wall of the injection molding machine 1. Multiple sorting bins 12 corresponding to the sorting guide tube 43 are placed on the upper surface of the tray 11. The sorting bins 12 are used to classify and store building blocks of different specifications or styles to avoid mixing.

[0032] In this embodiment, when using a building block injection molding device with automatic demolding function, the end of each corrugated hose 44 is first placed into the corresponding sorting bin 12 to ensure that building blocks of different specifications or styles can be accurately classified and stored. The first motor 24 is started, and its output shaft drives the U-shaped groove pulley 25 to rotate. Since the U-shaped groove pulley 25 clamps the sliding support rod 21, and the sleeve 29 slides with the sliding support rod 21, and the second ball 202 reduces the friction between the sleeve 29 and the sliding support rod 21, the pallet 22 moves horizontally along the sliding support rod 21 through the sleeve 29, realizing the horizontal adjustment of the translation mechanism; at the same time, the second motor 26 is started, and its output shaft drives the gear 27 to rotate. The gear 27 meshes with the rack 3, and the rack 3 slides in the groove 28. The first ball 201 reduces the friction between the rack 3 and the groove 28, and the protrusion at the top of the rack 3 prevents it from falling out of the groove 28, thereby driving the suction mechanism to move up and down, completing the height adjustment of the lifting mechanism.

[0033] Through the coordination of the translation and lifting mechanisms, the multiple vacuum suction cups 34 on the alignment plate 33 are precisely aligned with the building blocks of different specifications or styles being molded inside the injection molding machine 1. The cylinder 32 is activated, and its piston rod pushes the vacuum suction cups 34 to adhere to the surface of the building blocks. The vacuum suction cups 34, in conjunction with the suction mechanism, generate suction force, with each vacuum suction cup 34 holding a corresponding building block of a specific specification or style. The translation and lifting mechanisms are then adjusted again by the first motor 24 and the second motor 26, causing the material suction mechanism holding the building blocks to move, aligning the alignment plate 33 with the docking plate 41 on the support plate 4, and aligning each vacuum suction cup 34 with its corresponding alignment port 42 on the docking plate 41.

[0034] The control cylinder 32 pushes the alignment plate 33 closer to the docking plate 41, sending the building blocks adsorbed on each vacuum suction cup 34 into the corresponding alignment port 42. Then, the suction mechanism is turned off, causing the vacuum suction cups 34 to lose suction. Under the action of gravity, the building blocks pass through the alignment port 42, the sorting guide tube 43, and the corrugated hose 44 in sequence, and finally fall into the corresponding sorting bin 12, realizing automatic demolding and precise sorting of building blocks of different specifications or styles. Throughout the process, the locking blocks at both ends of the sliding support rod 21 prevent the tray 22 or the sleeve 29 from coming off. The first ball bearing 201 and the second ball bearing 202 reduce the sliding friction between the rack 3 and the groove 28, and between the sleeve 29 and the sliding support rod 21, respectively, improving the smoothness of the mechanism's operation. Manual sorting is not required, reducing labor costs and improving the efficiency and precision of simultaneous production of building blocks of multiple specifications.

[0035] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
