Horizontal line mould weight placing mechanism

Abstract

The invention relates to the technical field of casting equipment and provides a horizontal line mould weight placing mechanism which comprises a guide rail and a movable trolley. A support column isfixedly arranged on the movable trolley and is rotatably connected with a rotary column in a sleeving manner; the rotary column is fixedly connected with a lazy arm; a movable hoisting assembly is arranged on the lazy arm and comprises a movable rack; a winding roller and a hoisting motor driving the winding roller to rotate are mounted on the movable rack; a hoisting line for hoisting a mould weight is connected onto the winding roller in a winding manner; an overhead rail is further arranged on the lazy arm; and the movable rack is further connected with a movable wheel capable of moving along the overhead rail. According to the horizontal line mould weight placing mechanism, the lazy arm capable of rotating horizontally is arranged on the movable trolley, and the hoisting assembly is arranged on the lazy arm; an operator utilizes the hoisting assembly to place the mould weight on a sand mould to increase pressure of the sand mould, the possibility of box swelling or the gunfire phenomenon is greatly reduced, and the appearance inclination of a shrink hole in a casting is also reduced; and the horizontal line mould weight placing mechanism is low in operating strength, can hoista heavier mould weight, improves the technological safety and ensures the casting quality.

Description

technical field [0001] The invention belongs to the technical field of casting equipment, and in particular relates to a horizontal line weight placing mechanism. Background technique [0002] With the improvement of casting automation, the use of horizontal lines is becoming more and more extensive. Among them, the boxless molding line is widely used in the casting production of small and medium pieces. [0003] In recent years, with the transformation of the economy, various foundry manufacturers have undertaken a large number of different types of products in order to adapt to the market. Although boxless molding will place a box on the sand mold, for some products, due to their structure or weight, the box will expand or run out during pouring, which also leads to an increased tendency of shrinkage defects inside the casting. The reason for these phenomena is mainly due to the insufficient rigidity of the sand mold that lacks the fastening of the sand box. [0004] Th...

Problems solved by technology

However, the replacement cost of this method is too high, which is unbearable for small-scale manufacturers. Therefore, most of these products are abandoned or transferred to the traditional production method with sand boxes, which increases the production cost.

[0005] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
