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. Blo...

Abstract

An object of the present invention is to provide a blow molding machine capable of reducing the workload of carrying in and out metal mold parts. The blow molding machine has: a support member (510, 610) that supports a metal mold member that is loaded into or out of the blow molding machine; and a moving mechanism (520, 720) that moves the support member to a level toward the outside of the blow molding machine protruding protruding positions (P1, P5) and storage positions (P2, P6). The blow molding machine has a first fixed fulcrum shaft (20, 23), the base end of the support member is rotatably supported by the first fixed fulcrum shaft, and a first movable fulcrum shaft (513, 713 ). The moving mechanism includes a plurality of links (521, 522, 721, 722) rotatably linked to each other, and one of the links is rotatably supported on the movable fulcrum shaft of the supporting member. When in position, the plurality of connecting parts are maintained in a straight line by the first angle fixing member (530, 730), and the plurality of connecting parts become legs supporting the free end of the supporting 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. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanes...
