Description

Technical Field

[0001] This utility model relates to the field of precast slab production technology, specifically to a molding die for precast slab production. Background Technology

[0002] Precast concrete slabs are precast components made by pouring, vibrating, and curing standard concrete and other auxiliary materials through molds. First, according to the formula requirements, the raw materials such as cement, aggregates, sand, and additives are accurately weighed and mixed. Then, according to the size and shape of the precast slab, a suitable mold is selected, and the mold is cleaned and oiled. Finally, the mixed materials are poured into the mold and extruded into shape.

[0003] According to Chinese Utility Model Application No. CN202421859698.8, an easy-to-disassemble precast slab mold is proposed. The utility model describes that "the first and second moving mechanisms can be moved by the handle and casters. When the insert plate and the groove are inserted, the top of the base plate forms a complete plane. When the insert plate and the groove are far apart, the groove facilitates the demolding of the precast slab after molding. This effectively solves the problem that the device is not easy to move after assembly and is not easy to demold after the precast slab is formed in the prior art".

[0004] This easily detachable precast slab mold has a detachable base plate, base, side plates, and baffles. However, when producing precast slabs of the same width and height but different lengths, workers first remove the bases from the top of the two base plates, then move the two bases of suitable length to the designated position, then install the replaced bases on top of the two base plates, and install the two side plates of suitable length on both sides of the bases. Finally, they manually turn two screws to move the two baffles relative to each other, so that the replaced bases, the two replaced side plates, and the two baffles form the lower mold. Moreover, the formed precast slabs need to be moved from the top of the base to the edge of the base before being transferred. The replacement and material handling methods are cumbersome, time-consuming, and labor-intensive, affecting production efficiency. Therefore, a forming mold for precast slab production is proposed to solve the above problems. Utility Model Content

[0027] Specifically, the workers first install a bottom mold 4 of suitable length on the top of the table body 1, and two first side molds 5 of suitable length on the top of the bottom mold 4. Then, they move the adjusting mechanism 6 to the designated position. The bottom mold 4, the two first side molds 5, and the adjusting mechanism 6 form the lower mold.

Then, the extrusion mechanism 3 and the adjusting mechanism 6 are reset, and the two first side molds 5 are removed. Finally, the pushing mechanism 7 pushes the formed precast slab to the edge of the table body 1 for transfer. The replacement and material handling methods are relatively simple, saving time and effort and improving production efficiency.

[0028] In this embodiment, the extrusion mechanism 3 includes an electric push rod 31, which is fixedly connected to the top of the frame 2. The output end of the electric push rod 31 passes through the frame 2 and is fixedly installed with a lifting plate 32. Two longitudinal limiting plates are fixedly installed on the top of the lifting plate 32. The top of each of the two longitudinal limiting plates passes through the frame 2 and is fixedly installed with a longitudinal baffle. An upper mold 33 is detachably installed at the bottom of the lifting plate 32. The upper mold 33 matches the lower mold. An annular mounting plate is fixedly installed on the outside of the lifting plate 32. The annular mounting plate is threadedly connected to the upper mold 33 by first bolts installed at the four corners.

[0029] Specifically, by activating the electric push rod 31, the electric push rod 31 drives the lifting plate 32, the mounting plate and the upper mold 33 to move downward to the designated position, and the upper mold 33 cooperates with the lower mold to extrude and form the precast plate material.

[0030] In this embodiment, the adjustment mechanism 6 includes a chamber 61, which is fixedly connected to the bottom of the table 1. A dual-axis motor 62 is fixedly installed on the inner bottom wall of the chamber 61. Threaded rods 63 are fixedly installed on both output ends of the dual-axis motor 62. The threads of the two threaded rods 63 are opposite in direction and equal in length. The opposite sides of the two threaded rods 63 are rotatably connected to the inner side wall of the chamber 61 through bearings. Threaded sleeves 64 are threadedly installed on the outside of the two threaded rods 63. Movable rods 65 that penetrate and extend above the table 1 are fixedly installed on the top of the two threaded sleeves 64. The table 1 has movable holes at the top that match the movable rods 65. The two movable rods 65 are L-shaped. Movable plates 66 that fit against the side wall of the bottom mold 4 are fixedly installed on the opposite side of the two movable rods 65. Second side molds 67 are fixedly installed on the top of the two movable plates 66. The bottom mold 4, the two first side molds 5, the two movable plates 66, and the two second side molds 67 form the lower mold. The upper mold 33 matches the lower mold.

[0031] Specifically, by activating the dual-axis motor 62, the dual-axis motor 62 drives the two threaded rods 63 to rotate, and the two threaded rods 63 drive the two threaded sleeves 64, the two moving rods 65, the two moving plates 66 and the two second side molds 67 to move relative to each other to the designated position.

[0032] In this embodiment, handles are fixedly installed on opposite sides of the two first side molds 5. Insert plates extending into the bottom mold 4 are fixedly installed on the bottom of the two first side molds 5. The length of the two insert plates is less than the length of the first side molds 5. The top of the bottom mold 4 has slots that match the insert plates. The bottom mold 4 is threadedly connected to the top of the table body 1 by two second bolts. The two second bolts are located inside the slots. The bottom of the two insert plates has grooves that match the second bolts. Connecting plates extending into the two movable plates 66 are fixedly installed on the side walls of the two first side molds 5. Connecting grooves matching the connecting plates are opened inside the two movable plates 66. Sealing strips are fixedly installed on the inner walls of the slots and the inner walls of the connecting grooves.

[0033] Specifically, hold the two handles and place the two first side molds 5 on top of the bottom mold 4, so that the two insert plates are inserted into the interior of the two bottom molds 4 respectively. The two moving plates 66 and the two second side molds 67 move relative to each other until the two moving plates 66 are in contact with the sides of the bottom mold 4. The four insert plates are inserted into the interior of the two moving plates 66 respectively to form a sealing structure.

[0034] In this embodiment, the pushing mechanism 7 includes a vertical plate 71, which is fixedly connected to the top of the table body 1. A cylinder 72 is fixedly installed on the side wall of the vertical plate 71. The output end of the cylinder 72 passes through the vertical plate 71 and is fixedly installed with a pushing plate 73. Two transverse limiting rods are fixedly installed on the side wall of the pushing plate 73. The side of the two transverse limiting rods away from the side wall of the pushing plate 73 passes through the vertical plate 71 and is fixedly installed with a transverse baffle.

[0035] Specifically, by activating cylinder 72, cylinder 72 drives pusher plate 73 to move horizontally, and pusher plate 73 pushes the formed precast plate to the edge of table body 1 for easy transfer later.

[0036] The working principle of the above embodiments is as follows:

[0037] First, the workers install a bottom mold 4 of suitable length on top of the table body 1. Two first side molds 5 of suitable length are then placed on top of the bottom mold 4, allowing two insert plates to be inserted into the two bottom molds 4 respectively. The dual-axis motor 62 is then turned on, driving two threaded rods 63 to rotate. These threaded rods 63 move two threaded sleeves 64, two moving rods 65, two moving plates 66, and two second side molds 67 to their designated positions, ensuring the two moving plates 66 are in contact with the sides of the bottom mold 4. The four insert plates are then inserted into the two moving plates 66 to form the lower mold. Finally, the precast slab material is poured into the lower mold, and the process is completed. The electric push rod 31 is activated, which drives the lifting plate 32, the mounting plate, and the upper mold 33 of appropriate length to move downward to the designated position. The upper mold 33, in conjunction with the lower mold, extrudes and shapes the precast slab material. Then, the electric push rod 31 is activated to reset the upper mold 33, and the dual-axis motor 62 is activated to reset the two moving plates 66. The two handles are then grasped and moved upward to remove the two first side molds 5. Finally, the cylinder 72 is activated, which drives the pusher plate 73 to move horizontally. The pusher plate 73 pushes the shaped precast slab to the edge of the table body 1 for easy subsequent transfer. The replacement and material removal methods are relatively simple, saving time and effort and improving production efficiency.
