Tool for horizontal series connection casting and using method

Abstract

The invention discloses a tool for horizontal series connection casting and a using method. The tool comprises a bottom bracket, and further comprises a left supporting plate, a right supporting plate, a movable plate, two positioning guiding pins and a fastening lead screw, wherein the left side and the right side of the bottom bracket are respectively provided with two hanging handles, the left supporting plate and the right supporting plate are fixed to the two ends of the bottom bracket respectively and arranged in a face-to-face mode, a lead screw guiding hole with internal threads and guiding pin holes are formed in the right supporting plate, the two positioning guiding pins are fixedly connected to the movable plate and are in sliding fit with the corresponding guiding pin holes in the right supporting plate, and the fastening lead screw is in screw-thread fit with the lead screw guiding hole in the right supporting plate. The using method comprises the steps that a product sand mold is attached to the upper surface, where the left supporting plate is arranged, of the bottom bracket, next product sand molds are sequentially and continuously arranged in the direction of the movable plate in series, the fastening lead screw is rotated, the movable plate is pushed to move forwards until the movable plate is tightly attached to the product sand molds, and the product sand molds are tightly attached until no gaps exist. The tool is easy to operate and high in working efficiency.

Description

technical field [0001] The invention relates to a fixture tooling for sand casting and a use method thereof, belonging to the technical field of casting. Background technique [0002] Tandem casting technology has a long history in our country, and this casting technology is mainly suitable for batch casting of small and medium-sized pieces. This manufacturing technology has the characteristics of simple production process, short production cycle, high production efficiency, less molding material consumption and high process yield, so it has been widely used in the foundry industry at home and abroad. [0003] In actual production, several or dozens of sand molds are placed side by side and poured. The traditional method of most enterprises is to use pressed iron at the pouring site or place a sand box around the sand mold and fill a large amount of sand to fasten it. This tandem casting method is cumbersome to operate and not easy to transfer, and casting quality problems ...

Problems solved by technology

[0003] In actual production, several or dozens of sand molds are placed side by side and poured. The traditional method of most enterprises is to use pressed iron at the pouring site or place a sand box around the sand mold and fill a large amount of sand to fasten it. This tandem casting method is cumbersome to operate and not easy to transfer, and casting quality problems caused by sand flushing, sand swelling and even steel running during the pouring process occur from time to time, and the scrapping of castings is often batched, which is harmful to production. Enterprises have brought great trouble
