Abstract

PURPOSE:To enable automatic conveyance without requiring pallets and jackets by moving vertically a movable liner disposed in the spacing of a stationary liner by the revolution of an eccentric shaft and moving back and forth the casting mold by a guiding cylinder. CONSTITUTION:A moving frame 9 advances rods on both sides by extending the rod of cylinders and rotates an eccentric shaft 5 via a lever 10. The shaft 5 ascends by as much as the eccentric width and the frame 9 ascends, then the movable liner 2' receives the casting mold on a stationary liner 2. While a guiding cylinder 13 pushes and feeds the frame 9, the movable liner 2' moves by as much as one casting mold and moves the casting mold on top of a base frame 1. The casting mold on top of the liner 2' is thereafter placed atop the liner 2 by the reverse operation of the rod and the shaft 5. A stable pouring operation is carried out while the grasping plates 21 on top of a turning rod 17 grasp the side faces of the casting mold. Automatic conveyance is thus accomplished.

Description

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

Conventionally, with molds that are horizontally split into upper and lower molds, the upper and lower molds are supported by pallets, a jacket is attached to the outer circumferential surface, and the molds are transported, and then a weight is placed on the upper surface at the pouring position to pour the metal. The knotlets and jackets make it difficult to transfer molds in close contact, which lengthens the line, increases the equipment area, and requires a pallet and jacket recovery device, which tends to result in higher equipment costs. .

The tips of 0.2'O are loosely attached to the lower ends of the rotating rods 17, 17 that face each other front and back, and a bolt is provided protruding inward from the upper end of each rotating rod 17 to sandwich the upper and lower molds. A mounting plate 21 is attached freely, a bearing 22 is attached to the hollow underframe 1 at an intermediate position between each rotating rod pivoted to the front and rear surfaces of the upper end of the hollow underframe 1, and a weight support shaft 23 is attached to each bearing 22. are vertically supported and the weight support shafts 23 are opposed to each other on the front and rear surfaces of the hollow underframe 1, and the lower end of each weight support shaft 23 is connected to the horizontal frame 24 on the front and rear surfaces of the hollow underframe 1. , rotary shafts 25 are mounted on the lower part of the hollow frame 1 at appropriate left and right intervals, arm rods 26 are provided diagonally downwardly protruding from both outer ends of each rotary shaft 25, and the lower ends of the arm rods 26 are arranged on the outer side. The horizontal frame 24 at the lower end of the weight support shaft is supported by the roller 27 which is suspended loosely, and the weight operating shaft 28 is supported in the hollow frame 1 at a position above the center of each rotating shaft 25, and the weight operation The shaft 28 and each rotating shaft 25 are linked by an arm rod 29, and the weight operating shaft 28
A weight receiving plate 3 is connected to the rod of an extrusion cylinder 30 provided in the hollow frame 1, and a weight receiving plate 3 is connected to the upper end of each weight support shaft 23.
1 is fixed and a weight 32 is supported at four points by weight receiving plates 31 facing each other in the front and rear.

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 is supported at a constant height by pushing it upward through the roller 27 of the arm rod 26, and then the rod of the extrusion cylinder 19 is retracted into the cylinder and is pivoted to the operating shaft 18. V-shaped left and right connecting rods 20
The lower end of each rotating rod 17, which is pivotally connected to the hinge 16 on the front and rear surfaces of the hollow underframe 1 via the angle 20, is pulled inward of the hollow underframe 1, and the clamping plate 21 at the upper end is separated to the outside. It is. 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. Extend the rods of the extrusion cylinders 12, 12 at one end of the hollow frame 1, and move the rods 11 on both sides forward a little while moving the mold received on the upper surface of the rotary lever 1.
When each eccentric shaft 5 is rotated through 0 and the eccentric shaft 5 rises only during its eccentricity, the movable frame 9 rises and the upper surface of the movable liner 2' rises about 3 mm above the upper surface of the fixed liner 2. The movable liner 2' receives molds which are arranged in a continuous manner on the upper surface of the fixed 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 reversely operated again, and the eccentric shaft 5 is rotated 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. Each mold on the upper surface of the movable liner 2' is placed again on the upper surface of the fixed liner 2, 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. , fixed liner 2 and movable liner 2
The next mold formed by the molding machine is extruded from the traverser into the space at one end of the mold. 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. While opening the shaped left and right connecting rods 2'0.20, press the lower ends of the front and rear rotating rods 17.17 outward, and press the upper end clamping plate 21.
21 to clamp both sides of the upper and lower molds, and further reversely operate the extrusion cylinder 30 to rotate each rotation ↓.

While rotating the shaft 25 in the opposite direction, move the horizontal frame 2 on the front and rear sides of the hollow underframe 1.
4, each weight support shaft 23 is lowered, and the weight 32 supported at four points by the weight receiving plate 31 at the upper end of the weight support shaft 23 is placed on the upper surface of each upper and lower mold. Molten metal is poured into the upper and lower molds.

As described above, in the present invention, the movable liner placed in the gap between the fixed liners on the top surface of the hollow frame is moved up and down by rotating the eccentric shaft, and is reciprocated by the guide cylinder to create the continuous jointed upper and lower molds. A movable liner is used to transport the molds in synchronization with the molds sent out from the molding machine, and the pressing force n production force 1't'Jy is applied to each mold.
, t+ , <, Therefore, the mold can be made large and large objects can be cast.Moreover, during pouring work, both sides of the mold are clamped with the clamping plates 21, and the weight 32 supported at four points can be smoothly moved. It has the remarkable effects mentioned above, such as performing pouring work in a stable state while moving up and down, and automatically transporting molds without pallets or jackets.
