Abstract

The present invention provides a mold conveying guide device and an injection molding machine, wherein the mold conveying guide device conveys a mold to a mold fixing position in the injection molding machine and out of a mold fixing position in the injection molding machine to To be used when replacing the mold. A connecting arm is attached to the mold and protrudes in a direction in which the mold is transported to the mold fixing position. A guide roller is rotatably supported at a tip portion of the link arm. The guide roller is configured to rotate while in contact with a mold attachment surface of at least one of the fixed platen and the movable platen, and is configured to guide the mold such that the mold can approach or move away from the fixed platen and the movable platen. The at least one of the movable platens.

Description

[0001] The contents of Japanese Patent Application No. 2019-037983 filed on March 1, 2019, including specification, drawings and claims, are hereby incorporated by reference in their entirety. technical field [0002] The present disclosure relates to a mold conveyance guide for exchanging molds in the injection molding machine and an injection molding machine including the mold conveyance guide. Background technique [0003] In recent years, due to the subdivision of demand, the demand for multi-category production in small batches has been increasing in injection molding, and the frequency of replacement of molds used in injection molding machines tends to increase. However, since the mold used in the injection molding machine is a heavy object in the range of tens of kilograms to tens of tons, the operation of moving the mold when replacing the mold and the operation of fixing the mold at a predetermined position with high precision are operator burden. [0004] In addit...
