Embodiment 2

[0051] The structure and principle of this embodiment are basically the same as those of Embodiment 1. The basic similarities will not be described redundantly, and only the differences will be described. The difference lies in: the turntable 2 is set horizontally.

Embodiment 3

[0053] The structure and principle of this embodiment are basically the same as those of Embodiment 1, and the basic similarities will not be described repeatedly, only the differences will be described. The difference lies in: the cylinder body 3e1 of the oil cylinder 3e is fixed to one of the mold mounting plates 3b Connection, the piston rod 3e2 is fixedly connected with another mold mounting plate 3b.

Embodiment 4

[0055] The structure and principle of this embodiment are basically the same as that of Embodiment 1, and the basic similarities will not be described redundantly. Only the differences will be described. The axis line of the column coincides with the radial line of the turntable 2, and the number of guide columns is the same as that of the blow mold opening and closing device 3. The mounting seats 3f are rotationally connected in one-to-one correspondence.

Abstract

The invention provides a blow molding mold opening and closing device and a blow molding machine, belongs to the technical field of plastic processing, and aims at solving the problem of shortage of structure variety of an existing blow molding mold opening and closing device. The blow molding mold opening and closing device comprises a guide rod, two mold installation plates, an oil cylinder and a synchronous gear rack mechanism; the two mold installation plates are oppositely arranged in parallel; the two mold installation plates are connected with the guide rod in a sliding manner; the guide rod is fixedly connected with an installation seat; the synchronous gear rack mechanism is provided with a gear and two racks meshed with the gear; the two racks are fixedly connected with the two mold installation plates in a manner of one-to-one correspondence; the gear is rotationally connected with the installation seat; and a cylinder body of the oil cylinder is fixedly connected with one mold installation plate and a piston rod is fixedly connected with the other mold installation plate. The blow molding mold opening and closing device is capable of adjusting mold clamping force through adjusting oil pressure, so that the mold clamping force is matched with a mold, thereby improving the aesthetic property of a product and increasing the qualified rate of bottom sealing of the product; and furthermore, the blow molding mold opening and closing device has the advantage of being convenient to adjust.

Description

technical field [0001] The invention belongs to the technical field of plastic processing, and relates to a mold opening and closing device, in particular to a blow molding mold opening and closing device. [0002] The invention belongs to the technical field of plastic processing, and relates to a mold opening and closing device, in particular to a blow molding machine. Background technique [0003] Plastic bottle is a kind of raw material made of polyester (PETG), polyethylene (PE), polypropylene (PP), adding corresponding organic solvents, and after high temperature heating, through plastic molds through preform blow molding, extrusion blowing or Injection molded plastic container. Plastic bottles are mainly used for liquid or solid disposable plastic packaging containers such as beverages, food, pickles, honey, dried fruits, edible oils, agricultural and veterinary medicines, etc. [0004] In the process of manufacturing plastic bottles using the extrusion blow molding...
