Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for automatically transporting a mold formed by a molding machine.

Conventionally, in molds with horizontally divided upper and lower molds, the upper and lower molds were supported by pallets, and a jacket was attached to the outer circumferential surface to transport the metal while pouring with a weight placed on the upper surface at the pouring position. Because of the jacket, it is difficult to transfer the mold closely, which makes the line longer and the equipment area larger.
A recovery device for pallets and jackets was also required, which had the disadvantage that equipment costs tended to be relatively high.

In order to eliminate the above-mentioned drawbacks, the present invention aims to solve the above-mentioned problems by continuously feeding a rectangular mold with the same shape on the top and bottom without a pallet and without a jacket, holding the mold between clamping plates at the pouring position, and pouring the metal by placing a weight on the top surface. This is an automatic conveyance device designed to increase the size of horizontally split molds for efficient automatic conveyance, eliminate the need for a collection mechanism for pallets and jackets, and guide the weight to the top of the mold. It is characterized by being stable with four-point support.

Connected to 30 rods,
A weight receiving plate 31 is fixed to the upper end of each weight support shaft 23, and a weight 32 is supported at four points by the weight receiving plates 31 facing each other in the front and rear. It is something.

Next, the effects of the present invention will be explained with reference to embodiment figures.

In the automatic conveyance device 33 according to the present invention, the horizontal frame 24 at the lower end of the weight support shaft 23, which is pivotally supported on the front and rear surfaces of the hollow base frame 1, is moved by extending the rod of the extrusion cylinder 30 and rotating each rotating shaft 25. The weight 32 was supported at a constant height by pushing it upward through the roller 27 of the arm rod 26, and the rod of the extrusion cylinder 19 was further retracted into the cylinder to be retracted and pivoted to the operating shaft 18. V-shaped left and right connecting rods 2
Hinge 1 on the front and rear surfaces of the hollow underframe 1 through 0 and 20
The lower end of each rotating rod 17 pivotally connected to the hollow underframe 1 is pulled inward to separate the upper end clamping plate 21 to the outside. Therefore, a mold made by a molding machine and divided horizontally into upper and lower parts is successively transferred while being received by the fixed liner 2 and the movable liner 2' on the upper surface of the hollow frame 1 in a continuous joint. The mold received on the upper surface is extended by extending the rods of the extrusion cylinders 12, 12 at one end in the hollow frame 1, and while the rods 11 on both sides are slightly advanced, each eccentric shaft 5 is moved through the rotary lever 10. rotate it,
When the eccentric shaft 5 rises by its eccentric width, the movable frame 9 rises, and the upper surface of the movable liner 2' rises approximately 3 mm from the upper surface of the fixed liner 2, and the mold is placed on the upper surface of the fixed liner 2 in a continuous joint. is received by the movable liner 2'. Next, the guide cylinder 13 for guiding the movable frame 9 is operated to push the movable frame 9, while the movable liner 2' moves by one mold and is placed on the upper surface of the hollow frame 1 in a continuous joint. After that, the rod 11 is operated in reverse again, and the eccentric shaft 5 rotates in the opposite direction, so that the movable frame 9 is lowered, and the upper surface of the movable liner 2' is lowered to the same level as the upper surface of the fixed liner 2, and is movable. Each mold on the upper surface of the liner 2' is placed on the upper surface of the fixed liner 2 again, and then the guide cylinder 13 is operated in reverse to return the movable frame 9 and the movable liner 2' to their original positions. 2 and the movable liner 2', the next mold formed by the molding machine is extruded from the traverser.
In this way, the movable liner 2' is moved up and down and reciprocated to send out the molds in a continuous joint shape, and when a predetermined number of molds have been placed, the extrusion cylinder 19 pushes the operating shaft 18 to each V.
