Abstract
An injection molding apparatus including an injection machine, a mold conveying path following a rectangular pattern and starting from the injection portion of the injection machine and terminating thereat, a molded product removing means located adjacent to the terminal of the mold conveying path, a mold-direction turning means for a permanent mold, which is located at the corners of the path, and a drive means for moving permanent molds on the conveying path. In this apparatus, the permanent molds after injection are cooled during their travel on the conveying path. This apparatus is intended to give a full play to the function of an injection machine and saves the molding time of products to a great extent.
Claims2
An injection molding apparatus having a permanent mold conveying path comprising
- an injecting cylinder, a cylinder means for tightening a permanent mold, and an injection molding machine having an injection station between the injection cylinder and the cylinder means;
- a mold conveying path of rectangular pattern having a starting point adjacent a side of the injection station and terminating at a terminal adjacent an opposite side of the injection station;
- molded product removing means adjacent to the terminal of the mold conveying path and disposed at a right angle to the mold conveying path;
- mold direction turning means located at respective corners of the mold conveying path for turning the permanent mold in a direction facilitating the aligning and opening of the permanent mold consisting of two halves divided along a vertical plane in the molded product removing means;
- and
- means for conveying the permanent mold along the mold conveying path such that the portion of the permanent mold cooperating with the conveying means remains in the same plane with respect to the conveying path during conveyance along the entire mold conveying path.
