Description

Technical Field

[0001] The utility model relates to the technical field of ancient building brick and tile production equipment, in particular to a safety self-locking device for an ancient building brick and tile molding machine. Background Art

[0002] Existing antique building bricks and tiles are commonly made of synthetic resin materials. Synthetic resin bricks and tiles have many excellent properties such as light weight, high strength, waterproof and moisture-proof, anti-corrosion and flame retardant, sound insulation and heat insulation. The production process is to extrude the mixed materials after heating, and then use an ancient building brick and tile molding machine to mold them.

[0003] Since the temperature of the synthetic resin bricks and tiles just extruded is relatively high and the texture is relatively soft, it is necessary to solve the problem that the pressing head of the existing ancient building brick and tile molding machine adheres and deforms to the formed ancient building brick and tile during demoulding. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the utility model provides a safety self-locking device for an ancient building brick and tile molding machine.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A safety self-locking device for an ancient building brick and tile molding machine comprises a lower mold plate, an upper mold plate, a driving member, a buffer rod and a molding groove, wherein an air duct is arranged in the lower mold plate, an upper end opening of the air duct is arranged on a lower end surface of the molding groove, a lower end opening of the air duct is arranged on a side wall of the lower mold plate, and a one-way air valve is arranged at the lower end opening of the air duct.

[0007] Furthermore, the one-way air valve includes a cover plate, a mounting hole is formed on the cover plate, a mounting rod is arranged in the mounting hole, one end of the mounting rod is fixed to the side wall of the lower template, and a limiting rod is arranged at the other end of the mounting rod. The cover plate can slide left and right on the mounting rod, and a spring is mounted on the outside of the mounting rod between the cover plate and the limiting rod.

[0008] Furthermore, a slide groove is provided on the side wall of the profile groove, a stopper is installed in the slide groove for left and right sliding, a guide slope is processed on the stopper, and the stopper is connected to the slide groove through a reset spring.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] During molding, the punch is first pressed down slowly, and the air in the mold groove is discharged from the airway during the process of the blank gradually fitting with the bottom of the mold groove. After the air is discharged, the cover plate is reset to close the airway, and the block is squeezed back into the slide groove when the punch and the ingredients are lowered. After the mold is closed, the block will automatically pop out due to the lack of the blocking of the ingredients, realizing the limitation of both sides of the ancient building bricks and tiles. When the punch is separated, it moves upward quickly. At this time, the bottom of the ancient building bricks and tiles are tightly adsorbed on the lower end surface of the mold groove under the action of air pressure, avoiding the adhesion when the punch is separated, resulting in the deformation and scrapping of the bottom of the ancient building bricks and tiles caused by being pulled up. The utility model has a simple structural principle, and can solve the problem of adhesion and deformation when the synthetic resin ancient building bricks and tiles are separated from the punch when they are molded, and the punch can be separated without waiting for them to cool, which greatly improves the production yield and production efficiency.
