Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a mold setup device capable of automatically carrying in and out a mold used for molding processing to and from a molding machine.

<Related Art> Resin products such as automobile bumpers are formed by injection molding. In injection molding, a thermoplastic resin is injected into a closed mold to mold the mold, and when the product is changed, the mold is replaced. The molds are exchanged by loading a new mold directly into the clamping machine of the injection molding machine with a forklift every time the mold is exchanged.

<Problems to be Solved by the Invention> Since bumpers of automobiles have different shapes depending on the types of vehicles, a plurality of molding machines are juxtaposed to mold a plurality of types of bumpers. Therefore, when exchanging the dies, the forklift travels over a wide range, and it is necessary to replace the dies every time the forklift is exchanged, which is extremely inefficient. In addition, a space for the forklift and a space for exchanging the mold are required for each molding machine, and the space for the molding process is increased.

The present invention has been made in view of the above circumstances, and provides a mold setup device capable of automatically carrying in and out a mold to all molding machines, thereby improving the work efficiency of mold exchange and the molding process. It is intended to save space.

<Means for Solving the Problems> According to a configuration of the present invention for achieving the above object, there is provided a mold holding device for positioning and holding a loaded mold, a mold holding device and a plurality of molding machines. And a mold transfer device for receiving and transferring the mold between the mold holding device and a predetermined molding machine side; and a mold transfer device provided along a path of the mold transfer device. And a second mold holding device for receiving and transferring the mold, preheating and positioning and holding the carried-in mold.

<Operation> The mold is carried into the mold holding device, and is positioned and held. The positioned mold is received by the mold transfer device, is carried to the second mold holding device by the travel of the mold transfer device, is delivered to the second mold holding device, and from the second mold holding device. The preheated mold is received, transported to a predetermined molding machine by traveling of the mold transport device, and delivered to the molding machine side.

In addition to this, the preheated mold can be carried into the molding machine. As a result, it is possible to improve the working efficiency of the mold replacement and to save space in the molding process, and to start the molding work immediately after the mold replacement, thereby further improving the working efficiency.
