Abstract

PURPOSE:To perform casting free from leakage of molten metal and production of fins without using any heavy weight by using vertically moving rods which move by intersecting their upper parts orthogonally in dismounting of clamping means for molds used for casting on a cooling conveyor and mounting the same to molds which are not yet charged with molten metal on a charging conveyor. CONSTITUTION:A machine base 3 is provided orthogonally above a cooling conveyor line 1 and a charging conveyor line 2 which are provided in parallel. A carriage 6 provided with vertically moving rods 8 is run thereon. When a mold 15 which is charged with molten metal moves on the line 1, the carriage 6 in the upper part moves to above the mold and removes mold clamping means 16 by operating the rod 8 with a cylinder 7. In this state, the carriage moves to above the line 2, and mounts the clamping means to a combined mold 15' which is not yet charged with molten metal and is conveyed on the same conveyor line, then the carriage clamps the top and bottom molds firmly and transfers the mold to a charging site. Casting free from leakage of molten metal from the top and bottom molds and formation of fins is accomplished without using any heavy weight.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a mold clamping tool that tightens molds that are continuously transferred on a roller conveyor, or a mold clamping tool that is automatically detached by mold cooling conveyor fins. The molten metal is automatically conveyed to the pouring conveyor fins arranged in parallel and transferred to the mold before being poured. #This relates to an automatic transfer device for mold fasteners.

Conventionally, in casting, an upper mold and a lower mold are formed separately.After forming these molds, they are polymerized and poured into the desired shape through a pouring hole opened on the upper surface of the upper mold. The buoyancy of the hot water, the gas pressure, the head difference in the pouring, etc. can cause leakage of hot water from the gap between the parting surfaces, which are the mating surfaces of the mold, and the formation of cracks. The upper and lower molds are placed on the mold and strongly pressed to prevent leakage, cracking, etc. For this purpose, a device is used to transfer the weight from the cooling fins of the mold to the pouring fins. It is installed.

However, some of these Kengoku's lk- are 1 & 100 k, so I decided to hang it and use it for the 1st time. ! ! This requires a considerable amount of equipment, and its handling also requires highly skilled techniques.

The present invention does not use the above-mentioned needles, but strongly tightens the upper and lower molds, which are mold clamps formed by riveting the clamp frames that are attached oppositely to the catch claws at both ends of the clamp frame. If the mold is designed to prevent melt leakage, / The hanger chuck or clamp frame that hangs down from the underside of the running trolley that moves on the machine platform where the mold is to be installed is suspended by holding the eel one-button frame with its legs open, and then transferred to the pouring line in front of the IJk. Since the mold fasteners are changed over at the same time, the mold fasteners can be changed accurately using less expensive equipment compared to the conventional changing of weights, resulting in automation, labor savings, and casting speed. The aim is to dramatically improve the

To explain this with an example, a machine stand (8) is provided which is installed perpendicularly to the conveyor fins (1) and the pouring conveyor fins (2) which are installed in parallel, and the machine stand (8) ) is installed on both sides of the track (4). A lifting frame (9) is connected to the bottom of 8), and a pressing frame (11) is fitted with a spring (10) (10) on the lower surface of the lifting frame (9).
(11), and at both ends of the lifting frame (9),
The upper end of a hanger chuck (18) (18') provided with locking pieces (12) (12') whose lower ends face inwards is pivoted, and the upper ends of the hanger chucks (18) (18') on both sides are connected together. A cylinder (14) is attached to the cylinder (14) so that it can be opened and closed freely, and the cylinder (14) is continuously placed and transferred on the cooling conveyor line (1). The clamp frame of the mold clamping tool (16) that was tightening # mold (15) is transported with its legs open, and the mold (15') is placed on the pouring conveyor line (2) before pouring.
It is designed so that it can be transferred to the top, and is shown in (17) (

j While the feed equipment (16) is suspended, the feed equipment (16) is suspended from the cooling conveyor line (1) onto the casting mold (15') in front of the pouring conveyor fin (2) arranged in parallel with the cooling conveyor line (1). Transfer the unpoured metal onto the mold (15')? The mold clamping tool (16) is changed by operating in the opposite direction from the previous one.

The present invention is an LA factory where a cooling conveyor line (1) and a pouring conveyor fin (2) are installed side by side - in other words, a mold clamping tool (16) is installed across the sickle perpendicular to the IC plane, and a mold clamping tool (16) is installed with a simple device. Since it is designed to be used for transfers, it is possible to effectively feed the fastener (16) using a smaller installation area compared to the conventional method, and to suspend it from the lower surface of the lifting frame (9). Spring (10) (10) VIMm pressing frame (11
