Claims (2)

1. 1. A mold molding apparatus, comprising: an injection pot for injecting the foamed kneaded material into a cavity of a mold from an injection port; a cover member for opening and closing an upper opening of the injection tank; A stirring mechanism for stirring the foaming mixture in the injection kettle; An up-and-down driving mechanism for vertically moving the cover member and the stirring mechanism along the depth direction of the injection kettle; a connecting portion for releasably connecting the injection vessel and the cover member; A stopper plate having a stopper for opening and closing the injection port, and A driving mechanism for moving the stopper plate in the horizontal direction, Wherein, when the connecting part is used for connecting the injection kettle and the cover member to be integrated, the up-and-down driving mechanism moves the injection kettle, the cover member and the stirring mechanism up and down together, and When the connection part releases the connection between the injection kettle and the cover member, the up-and-down driving mechanism moves the cover member and the stirring mechanism up and down without moving the injection kettle up and down, The injection tank is mounted on the stopper plate in a state where the connection between the connection portion and the cover member is released, and is movable in the horizontal direction in accordance with the movement of the stopper plate by the driving mechanism.
2. 2. The mold molding apparatus according to claim 1, wherein the coupling portion has a clamp pin, a clamp sleeve provided to the injection pot, and a driving portion that drives the clamp pin.

Description

Mold shaping device Technical Field The present invention relates to a mold molding apparatus for press-filling a foam kneaded material into a cavity of a heated mold to mold a mold. Background In recent years, for the reason of good collapse after casting, it has been proposed to mold a casting mold by using a water-soluble binder as a binder for a particulate aggregate and evaporating water by heating to cure the water-soluble binder. For example, patent document 1 discloses a mold molding apparatus that produces a foamed mixture that is a material for such molding and injects the foamed mixture into a cavity of a mold by using air. The mold molding device 110 of patent document 1 shown in fig. 9 includes a groove 120 formed through the bottom of the filling hole 122, a stopper mechanism 118 for opening and closing the filling hole 122, and a cover member 130 for closing one side of an opening 120K in the groove 120. Further, the mold molding apparatus 110 includes a stirring mechanism 112 having a stirring blade 140 provided at a lower portion thereof, and a compressed air supply mechanism 150 for supplying compressed air into the tank 120 when the foaming mixture is filled into the cavity of the mold 160 from the filling hole 122. Further, the mold molding apparatus 110 includes a hydraulic cylinder 172Y for moving the tank 120 in the up-down direction, a servo hydraulic cylinder 116Y for moving the cover member 130 in the up-down direction, and a servo hydraulic cylinder 144Y for moving the stirring blade 140 in the up-down direction. That is, the mold molding apparatus 110 has a dedicated drive train for each of the constituent members that move in the vertical direction. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2018-192512 Disclosure of Invention Problems to be solved by the invention With the mold molding apparatus of patent document 1, the respective constituent members that move in the vertical direction have dedicated drive trains, and the apparatus configuration is complex. These components are controlled to move in the vertical direction. Therefore, the cycle time from kneading to injection is relatively long. In view of the above, the mold molding apparatus of patent document 1 has room for simplifying the apparatus configuration and for shortening the cycle time from kneading to injection. Accordingly, an object of one embodiment of the present invention is to realize a mold molding apparatus that has a simplified apparatus structure as compared with the prior art and that shortens the cycle time from kneading to injection as compared with the prior art. Means for solving the problems In order to solve the above problems, a mold molding apparatus according to one aspect of the present invention includes an injection pot for injecting a foamed kneaded material from an injection port into a cavity of a mold, a cover member for opening and closing an upper opening of the injection pot, an up-and-down drive mechanism for vertically moving the cover member along a depth direction of the injection pot, and a connecting portion for releasably connecting the injection pot and the cover member. ADVANTAGEOUS EFFECTS OF INVENTION According to one aspect of the present invention, a mold molding apparatus having a simple structure and a reduced cycle time as compared with the prior art can be provided.
