DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a mold device in an injection molding machine or the like for molding synthetic resin material or the like, and particularly to a mold device for revolving and pivoting a mold when the mold is opened, making use of the mold opening and closing operation.
TECHNICAL BACKGROUNDS
In the past, in the mold device in an injection molding machine or the like, when a molded article after molding is removed from the mold, a kind of industrial robot called a clamp is moved into a space of the opened mold, whereby the molded article is held by the robot which retreats from the mold space, and the molded article is recovered at a predetermined recovery location. More specifically, tile molded article is removed by a series of operations which include mold opening, entry of the clamp, holding of the molded article by the clamp, retreat of the clamp, release of the molded article from the clamp, and recovery of the molded article.
In the above-described prior art, the removal of the molded article is carried out using a kind of industrial robot called a clamp. Accordingly, a space for installation of the robot and a space for operation thereof are required. The prior art thus has problems such that the whole device becomes large-sized, and that because of the complicated and high-degree operation of the robot, the whole device also becomes complicated and high-degree accordingly, inevitably resulting in an increase in equipment cost. To solve the above-mentioned problems is thus an object of the invention.
DISCLOSURE OF THE INVENTION
According to this invention, in view of problems mentioned above caused by a restriction placed on the construction of the mold device in an injection molding machine described above with respect to the prior art, either the fixed mold or movable mold to be relatively opened and closed is revolved and pivoted through a predetermined angle by taking advantage of the mold opening and closing operation. More specifically, the aforementioned problems are solved by an arrangement wherein a revolutionary block is supported revolvably and pivotably with respect to a block supporting plate detachably mounted on a retainer plate, wherein either of the molds is mounted on the revolutionary block, and revolutionary means is provided, the means comprising an operating rod for revolving the revolutionary block by taking advantage of the mold opening and closing operation.
The arrangement of this invention is operated as follows. When, after molding, the clamping cylinder retreats and the movable mold retreats to open the mold, the revolutionary block is revolved and pivoted by the revolutionary means in response to the mold opening operation. Upon completion of mold opening, the revolutionary block is revolved through a predetermined angle, thus either the fixed mold or movable mold mounted on the revolutionary block is revolved and pivoted through a predetermined angle to tilt the mold surface outside the operating space, where the ejected molded article is disengaged from the mold and falls by gravity, and the molded article is automatically recovered into a recovery box or the like via a predetermined chute.
