The empty conveyor truck that has been transferred is Drag it back to the working position. The bottomless mold falls down and matches the mold bottom plate on the empty conveyor to start the next pouring work. In the process of transferring finished product blocks, the existing fully automatic block forming machine uses hydraulic clamps to clamp the gypsum blocks, transport them to a designated location, unload them, and then transfer them to relevant self-propelled machines for re-carrying into storage or loading. This method It is necessary to clamp the blocks twice in succession, which may cause unnecessary damage to the blocks. The invention arranges fixed pulleys and traction power devices on opposite sides of the frame, with the frame between them. By adjusting the rotation direction of the output end of the traction power device, the movement direction of the conveyor vehicle can be changed, allowing the conveyor vehicle to alternate with and without The bottom mold cooperates to form a mold cavity, which can ensure the continuity of pouring work and improve work efficiency; when the conveyor truck carries the gypsum blocks away from the work area, it has a long time for the gypsum blocks to solidify, which can achieve the same goal without changing the unit time. While increasing the output of blocks, the curing time of each gypsum block before being clamped is extended, so that the hardness of the blocks during transportation is high enough and not easily damaged, which can improve product quality.

The operating method of a gypsum block forming device of the present invention includes the following steps:

Step 1. The hydraulic pump station is powered on, and the mixing device in the feeding device works to stir the gypsum slurry evenly. The hydraulic device makes the bottomless mold contact and cooperate with the mold bottom plate;

Step 2: The feeding device pours the gypsum slurry into the mold cavity from the pouring port on the upper side of the mold. After the gypsum blocks have hardened properly, the scraper unit completes shaping the upper surface of the blocks. After the gypsum blocks are solidified and formed, the hydraulic device lifts upwards, driving the bottomless mold to move upwards. Thereby, the stationary ejector pin ejects the blocks from the bottomless mold, and the blocks are left on the stationary mold bottom plate to complete the demoulding process.

Step 3: The traction power device of the trolley is started, and the trolley is driven to drive the gypsum blocks resting on the mold floor to be transported along the preset track to the designated location, and then the relevant self-propelled machines or staff are put into storage or loaded into the truck to complete the transfer. Work. At the same time, another car stops under the bottomless mold, and the bottomless mold falls under the driving of the hydraulic lifting device and matches the top bottom plate of the car.
