Adjustable shell molding line sand box used for casting

Abstract

The invention provides an adjustable shell molding line sand box used for casting. The adjustable shell molding line sand box comprises a box body. The box body comprises four side plates, a box bottom and a frame. The adjustable shell molding line sand box is characterized in that: vertical guide slots are formed in one pair of the side plates of the box body; clamping slots are formed at corresponding positions on the box bottom; and vertical separators are inserted into the clamping slots in the box bottom along the vertical guide slots so as to divide the box body into a plurality of small box bodies. Two to four rows of multi-stage locating clamping blocks are arranged on the upper half part of one pair of the side plates of the box body. Vertical insert holes are formed in the locating clamping blocks. Two to four height adjusting mechanisms are arranged in the box body. The height adjusting mechanisms include transverse U-bars; two ends of each transverse U-bar are respectively hinged with two vertical bars at two sides; locating blocks protruding towards the outside are arranged on the upper ends of each two vertical bars. Pin holes are formed in the locating blocks. The locating blocks and the pin holes in the locating blocks are matched with the locating clamping blocks and the vertical insert holes. Pins penetrate through the vertical insert holes of the locating clamping blocks as well as the pin holes in the locating blocks so as to lock the lifting adjusting mechanisms. Threaded holes are formed in the uppermost guide slots in the pair of the side plates; and two sides of each of the uppermost guide slots are connected and fixed through a bolt and a nut.

Description

technical field [0001] The invention relates to an adjustable shell molding line sand box for casting, which belongs to the technical field of casting process equipment. Background technique [0002] In the foundry industry, the shell molding line that uses steel shot instead of coal powder clay to fix the core is widely used. Generally speaking, the quality of the sand box in the circulating automatic line is very important. On the one hand, it must be able to withstand the strength requirements of very heavy steel shots, and on the other hand, it must meet the production requirements of various castings to achieve common box and line production. For example, the casting products include front axle, rear axle, cylinder head, exhaust manifold, etc. The external dimensions of the products are very different, so there is no large sand box suitable for this type at present. Contents of the invention [0003] The purpose of the present invention is an adjustable shell molding...
