Description

Technical Field

[0001] The utility model relates to the field of concrete test molds, and more specifically, to a concrete test mold. Background Art

[0002] The concrete mold trial is to pour unsolidified concrete into the mold, and then demold it after solidification. The demolding process is divided into air compressor demolding and manual demolding, but the air compressor cannot demold multiple molds. Generally, factory air compressors are not equipped according to the number of molds, so manual demolding is necessary. However, manual demolding first requires finding two discarded molds to pad underneath, and then adjusting the distance between the two discarded molds, and slowly demolding through the reaction force generated by knocking, which is very troublesome. Utility Model Content

[0007] Furthermore, the driving main component includes two pulleys, two belts, a rotating head, a main pulley, a transmission chamber and a threaded sleeve; the transmission chamber is opened on the lower side of the air groove, and two threaded shafts extend into the transmission chamber and are fixedly connected to the two pulleys respectively, the threaded sleeve is rotatably installed in the transmission chamber and is located between the two pulleys, the main pulley is fixedly installed on the threaded sleeve, the main pulley and the two pulleys are connected by two belts respectively, and the rotating head can be fixedly connected to the threaded sleeve; the threaded rod extends into the transmission chamber and is threadedly connected to the threaded sleeve, and the two pulleys are rotated at the same time by rotating the main pulley, and the propulsion plate can be controlled to propel the air, completing one-point multi-control, which is more convenient.

[0008] Furthermore, a protrusion is provided in the rotating head and an inner groove is provided in the threaded sleeve.

The threaded support can improve stability.

[0022] like Figure 3 As shown, the driving main component 3 includes two pulleys 31, two belts 32, a rotating head 33, a main pulley 34, a transmission chamber 35 and a threaded sleeve 36; the transmission chamber 35 is opened on the lower side of the air groove 24, and the two threaded shafts 26 extend into the transmission chamber 35 and are fixedly connected with the two pulleys 31 respectively, the threaded sleeve 36 is rotatably installed in the transmission chamber 35 and is located between the two pulleys 31, the main pulley 34 is fixedly installed on the threaded sleeve 36, the main pulley 34 and the two pulleys 31 are connected respectively by two belts 32, and the rotating head 33 can be fixedly connected with the threaded sleeve 36; the threaded rod 27 extends into the transmission chamber 35 and is threadedly connected with the threaded sleeve 36, and the two pulleys 31 are rotated at the same time by rotating the main pulley 34, and the propulsion plate 25 can be controlled to propel the air, completing one-point multi-control, which is more convenient.

[0023] like Figure 4 As shown, a protrusion is provided in the rotating head 33, and an inner groove is provided in the threaded sleeve 36. When the protrusion enters the inner groove, the rotating head 33 and the threaded sleeve 36 are fixedly connected. The protrusion and the inner groove are manually matched to ensure that there will be no operational errors that lead to inconvenient demoulding. A material-saving groove is provided around and on the bottom surface of the housing 1. The material-saving groove is fixed by a reinforcing rib, and the rotating head 33 extends into the material-saving groove on the bottom surface.

[0024] like Figure 2 As shown, when demoulding is required, the entire mold is turned upside down first, and then an air compressor is used, and the air compressor is aimed at the through groove 4, and then the gas is discharged to the air groove 24 through the one-way valve 5, and then continues to be discharged to the mold groove, so that the bottom plate 23 is pushed by the air pressure, so that the demoulding of the solidified concrete is completed.

At the same time, because the solidified concrete is first pushed a distance by the air, the mold as a whole is manually lifted, and then the support plate 21 is repeatedly collided with the ground to complete the vibration so that the concrete demoulding is completed.
