Problems solved by technology

[0002] In the positive and negative pressure thermoforming machine processing industry, the products are made of plastic sheets that are baked in a hot box, heated and softened, and then molded in a special mold. Here, it is generally necessary to check the relative position of the fixed mold mounting plate and the movable mold before molding. The adjustment of the longitudinal vertical position and the horizontal position is generally carried out manually in the prior art, and the adjustment is performed by locking nuts on both sides of the formwork. Its structure is simple, and the adjustment is difficult, and the efficiency of mold adjustment is low. low adjustment accuracy

Abstract

The invention belongs to the technical field of plastic forming devices, and provides a mold adjusting and locking mechanism of a positive and negative pressure thermoforming machine. The mold adjusting and locking mechanism comprises a fixed mold plate and a movable mold plate. Upper guide cylinders are arranged at four corners of the fixed mold plate. Lower guide cylinders opposite to the upper guide cylinders are arranged on the movable mold plate. Four longitudinal mold adjusting and locking assemblies are correspondingly arranged at the four corners of the fixed mold plate. Transverse mold adjusting and locking assemblies are arranged on the movable mold plate. The mold adjusting and locking mechanism has the beneficial effects that adjustment, in the vertical position direction, of the fixed mold plate and the movable mold plate can be conducted through the longitudinal mold adjusting and locking assemblies, the installation position of the movable mold plate can be fixed through the transverse mold adjusting and locking assemblies, meanwhile, a mold on the movable mold plate can be driven to conduct adjustment in the transverse direction, the whole mold adjusting and locking process is convenient and rapid, and mold adjusting is high in speed, stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of plastic molding devices, and in particular relates to a mold adjusting and locking mechanism of a positive and negative pressure thermoforming machine.
