the control unit allows the mold to be opened using the mold clamping unit when the unlocking state of the opening prevention mechanism of the mold device attached to the mold clamping unit is detected.

Technical Field

The present application claims priority based on japanese patent application No. 2018-163965, applied by 8/31/2018. The entire contents of this Japanese application are incorporated by reference into this specification.

The present invention relates to an injection molding system.

Background

Patent document 1 describes a molding method using a plurality of molds, as follows: when the mold to be transferred is attached to the molded article take-out device, the opening prevention mechanism provided in the mold is released. Further, the following are disclosed: the mold from which the molded product has been taken out is closed and opened to prevent locking, and is transferred to the next step.

Patent document 1: japanese patent No. 2610120

However, as an opening prevention mechanism for preventing the mold from being opened during the transfer, for example, a method of fixing a plate body to a movable mold and a fixed mold with bolts is known. In this method, after the mold is mounted on the body, the operator needs to detach the bolt and the plate body. Therefore, even if the mold exchange work can be automated using the automatic mold exchanging carriage, a worker is required to detach the bolt or the plate, and there is a problem that the automation cannot be achieved. Further, if the mold is opened before the bolt or the plate is removed, there is a risk that the bolt or the plate is broken or the mold is damaged.

Disclosure of Invention

Accordingly, an object of the present invention is to provide an injection molding system capable of appropriately performing mold replacement.
