Abstract

PURPOSE:To make mass production of products by automatically crushing a molding sand and shaking out the sand from gate surfaces by oscillating actions at the terminal side for transportation of casting molds, then breaking gates and dropping and collecting only the products. CONSTITUTION:The molding sand is crushed by the oscillating actions of a pair of oscillation inducing rods 11 on the terminal side for transportation of the continuously transported casting molds 1. The gates 3 molded in the molds are nabbed by an oscillation transferring device 6 and are transferred toward a discharge side. The transferred gates 3 are held in a horizontal state and the molding sand sticking thereto is automatically shaken out by a shaking out device 19. The gates 3 from which the sand is shaken out are sent along guide rails 29 to a gate breaking device where the gates 3 are broken and only the products are dropped and collected. The respective operations of the sand crushing of the casting molds, the cleaning of the gates and the gate braking are continuously and automatically executed in this way.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a vibration transfer operation in which a mold is crushed by vibration operation and a molded weir is vibrationally transferred to a casting sand removal device in a non-rotating state. Casting that can automatically and continuously perform sand removal work to remove molding sand that adheres to the weir surface during transport and weir folding work to remove and collect products that are integrally attached to the weir. Related to process automation equipment.

[Prior Art] Conventionally, a mold filled with a molding machine such as a jolt, squeeze, or stripper machine is placed on a continuously moving conveyor, and during the movement, metal is mechanically poured from a ladle, and then The poured mold is sent to a sand removal device, where the casting and frame are separated, and the casting frame is returned to the molding machine on a conveyor, and the dropped sand is sent from here to a sand treatment device via a magnetic separator. The casting process, in which the remaining castings were cleaned and finished by sandblasting or tumbler to remove the molding sand adhering to the surface, was completed before the filing of this application, for example, on September 30, 1964.
It is well-known as it is listed in the World Encyclopedia 2 published by Heibonsha in Japan, in the column ``P22Or foundry''.

[Problem to be solved by the invention] By the way, in the conventional casting process of this type, the work of taking out the casting from the vI mold and the work of removing sand were performed individually by many workers, and the resulting In order to move the castings one by one to the next work process, workers must be used to transport them one by one, which requires a lot of labor, and it is not possible to automate the casting process, which can be achieved efficiently and labor-savingly. It had some problems.

The present invention has been made in view of the above-mentioned problems of the conventional technology, and its purpose is to eliminate internal problems even when a large number of products are cast using a weir. The work of taking out the weir molded in the weir from the mold and the work of removing molding sand adhering to the surface of the weir can all be carried out in a continuous and consistent manner,
The present invention aims to provide an automation device for the casting process that aims to automate the 8B manufacturing process and mass-produce products.

[Means for Solving the Problems] In order to achieve the above object, in the casting process automation device of the present invention, a pair of left and right vibration induction rods are installed at the end of the conveyance of the mold, which is continuously conveyed. , a vibration transfer device that breaks up the foundry sand by back-and-forth vibration action and transfers it toward the discharge side under the non-rotating bran while hooking the protruding neck of the weir molded inside in a hanging manner; and the vibration transfer device. A casting sand removal device that automatically removes molding sand adhering to the surface of the weir while the transferred weir is in a horizontal state and transferred from the supply side to the discharge side; After being transferred and placed on the lower mold along the pair of left and right guide rails,
A weir folding device that performs weir folding by lifting and lowering the upper die and collects only the products by falling is arranged in a continuous manner.

The left and right sides of the protruding neck, which is integrally attached to the upper part of the weir, are formed into parallel flat surfaces to prevent the weir from rotating unnecessarily during vibration transfer work, and to pass it on to the next process in an orderly manner. You can give the name.

Further, guide projections are attached to the back surfaces of both sides of the weir so that the weir from which sand has been removed can be accurately supplied to the weir folding device along a pair of left and right guide rails.

Moreover, the weir to which a suitable number of products are attached is formed as a whole in the shape of a rectangular bar, so that a large number of weirs can be automatically and sequentially supplied to the weir folding device.

[Operation] Now, a large number of castings with weirs molded inside them are successively conveyed toward the discharge side in a continuous manner in an adjacent state.

The molds, which are sequentially conveyed to the conveyance end side by the conveyance action, vibrate in the vertical and front-back directions and are hooked in a hanging manner between a pair of left and right vibration induction rods, and are not rotated by the vibration action. It is transferred to the discharge side depending on the condition. In addition,
The foundry sand broken up by the vibration is dropped onto the rotating conveyor in one direction, collected and processed as appropriate, and is transferred to the discharge side (directed in this direction) in a hanging shape by the vibration transfer device. A large number of weirs are dropped one after another from the ends of a pair of left and right vibration induction rods onto a pair of left and right conveyor belts in a horizontal state.By the way, a pair of protrusions are provided on the back side of each weir. Furthermore, since the pair of protrusions are located on the outside of the pair of left and right conveyor belts, and the weir is mounted on the conveyor belt, the weir is fed to the casting sand removal device in an accurate posture, and any sand that adheres to the weir is fed to the casting sand removal device. The molding sand is removed and cleaned.

A large number of cleaned weirs are then conveyed one after another to the pair of left and right guide rails by the conveying action of the rotation of the conveyor belt. During this transfer, the pair of guide protrusions protruding from the back side of the weir are fitted into the pair of left and right guide rails, respectively, and
Since the weir located at the front is pushed by the protruding neck of the weir located next, a large number of weirs are sequentially transferred onto the lower die of the weir folding device along the pair of left and right guide rails. Once the weir is positioned on the lower mold, the upper mold is lowered and the weir folding operation is performed to break off the products attached to the weir, allowing the products to fall and be collected, and after the products have been broken off, the weir is sequentially It falls into the pushed out collection box and is collected.

Therefore, by the above-described operation, the entire process from casting sand removal to weir folding can be automated and products can be efficiently obtained.
