Embodiment Construction

[0015] The invention discloses an indexing plate of a one-step full-automatic plastic injection blow molding machine, in particular relates to a tensioning mechanism of the indexing plate. There is an indexing plate body 1, and the periphery of the plate body is made of equal parts. Three indexing grooves 11, as shown in Figure 1 and Figure 2, the centerlines of each indexing groove are 120° apart, and the indexing grooves cooperate with the toggle mechanism of rotary motion, and the toggle mechanism drives the index plate to rotate each time 120°. A tensioning mechanism is installed in the disk body, and the tensioning mechanism is fixed with the main shaft 7, as shown in Figure 1, the tensioning mechanism is an inner tensioning ring 8 matched with the outer wall of the main shaft 7 and the inner hole of the disk body 1. The matching outer tension ring 5 and the inner tension ring 8 have tension grooves 82, as shown in Figure 9, and the outer tension ring 5 has tension groove...

Abstract

The index plate tensing mechanism for plastic injection molding machine has one index plate body with three equant index slots, tension mechanism inside the index plate body and fixed to the main shaft, inner tension ring fitting the outer wall one the main shaft and with tension slot, outer tension ring fitting the inner hole of the index plate body and with tension slot, and upper clamping block and lower clamping block between the inner and the outer tension rings and fixed with fastening screws. The inner tension ring has outer cones on its two ends, the outer tension ring has inner hole with conic ends, and the upper clamping block and the lower clamping block have inner and outer walls with conic surfaces. The present invention can regulate the position of the main shaft via regulating the screws on the upper clamping block and the lower clamping block.

Description

technical field [0001] The invention relates to equipment for processing plastic hollow containers, in particular to a tensioning mechanism for index plates of a one-step automatic plastic injection blow molding machine, belonging to the field of plastic machinery. Background technique [0002] Using plastic (mainly referring to PE, PP, PC) as raw material, it is processed into hollow containers (plastic bottles) by injection blowing, such as medicine bottles, cosmetic bottles and food bottles, etc., which can be applied to automatic plastic injection blow molding machines. There are two parts of injection molding and blow molding, and the injection and blow molds are installed on the same workbench, which is divided into three stations: injection molding, blow molding and demoulding. The three stations rely on a turret to drive the workpiece, and the turret is triangular in shape. Mandrels are respectively installed on each side of the triangular turret, and the mandrels co...
