Embodiment Construction

[0094] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to comparative examples. In addition, the present embodiment described below does not unduly limit the content of the present invention described in the claims, and all the configurations described in the present embodiment are not necessarily essential as solutions of the present invention.

[0095] 1. Blow molding machine

[0096] The blow molding machine according to the present embodiment described below exemplifies the same drive method as that of the rotary transfer type four-station blow molding machine described in Patent Document 1, but it is not limited to the blow molding machine except for some embodiments. this. The blow molding machine of Patent Document 1 injects and molds a preform (parison) through an injection molding section, and carries the preform into the blow molding section through a lip mold for injection molding to blow mold a container.

Abstract

An objective of the present invention is to provide a blow molding machine that can reduce the workload for loading and unloading mold components. The blow molding machine has: a support member (510, 610) that supports a mold component to be loaded or unloaded into the blow molding machine; and a moving mechanism (520, 720) that moves the support member between a protrusion position (P1, P5), in which the support member horizontally protrudes in a direction away from the blow molding machine, and a housed position (P2, P6). The blow molding machine has a first fixed support shaft (20, 23). The base end of the support member is rotatably supported by the first fixed support shaft, and the free end of the support member is provided with a first movable support shaft (513, 713). The moving mechanism comprises a plurality of links (521, 522, 721, 722) that are rotatably coupled to each other, and one of the plurality of links is rotatably supported by the movable support shaft of the support member. When the support member is set to the protrusion position, the plurality of links are maintained in a linear shape by a first angle locking tool (530, 730), and the plurality of links act as a leg that supports the free end of the support member.

Description

technical field [0001] The present invention relates to a blow molding machine, a method of mounting metal mold parts, and a metal mold unit. Background technique [0002] For example, in the blow molding machine shown in Patent Document 1, many metal mold parts are used. Since the mold parts are formed according to the size and shape of the blow-molded container, if the size and shape of the container are changed according to the production lot, the mold parts have to be replaced. [0003] In the case of mass production of identical containers, the frequency of replacement of metal mold parts is low. However, in recent years when the types of containers to be molded have increased, and the number of batches has increased due to the large number of types, it is necessary to reduce the burden of mold part replacement work if the frequency of replacement of mold parts is increasing.
