Anticollision upper blocking machine

Abstract

The invention relates to an anticollision upper blocking machine and belongs to the field of sand faced iron mold casting equipment. The machine comprises an upright, a rack, an air cylinder articulated seat, a telescopic air cylinder, an air cylinder articulated joint, a driving connecting rod, a driven connecting rod I, a driven connecting rod II and a baffle, wherein an articulation seat I and an articulation seat II are arranged on the rack; the air cylinder articulated seat is fixed on the upright; one end of the telescopic air cylinder is connected with the air cylinder articulated seat; the other end of the telescopic air cylinder is connected with the air cylinder articulated joint; the driving connecting rod is connected with the air cylinder articulated joint; one end of the driven connecting rod II is connected with the driving connecting rod; the other end of the driven connecting rod II is connected with the articulation seat I; one end of the driven connecting rod II is connected with the driving connecting rod; the other end of the driven connecting rod II is connected with the articulation seat II; and the baffle is fixed on the driven connecting rod. The machine is reasonable in structure, can realize an anticollision function; the baffle cannot be burst through when the traveling speed of an iron mold is too high or the air pressure is insufficient; and smooth operation of a production line is ensured.

Description

Technical field [0001] The invention relates to a box stopper, in particular to an anti-collision type upper box stopper, which belongs to the field of iron-type sand-coated casting equipment. Background technique [0002] In the iron mold sand-coated casting production line, the upper box machine is fixed above the roller table of the production line to block the moving iron mold and play the role of positioning and accumulating iron molds. Attached figure 1 It is an upper box machine with a traditional structure. It is designed with two hinge points. The disadvantage of this box machine is that when the moving iron type runs too fast or the air pressure of the telescopic cylinder 4 is insufficient, the baffle 9 will be opened. Cause the iron type to slip out of the positioning position and disturb the normal operation of the production line. figure 1 Middle: There is an offset between the blocking iron sign and the open sign.

Problems solved by technology

attached figure 1 It is a box-up machine with a traditional structure, designed for two hinge points. The disadvantage of this box-up box machine is: when the moving iron mold runs too fast or the air pressure of the telescopic cylinder 4 is insufficient, the baffle plate 9 will be flushed open. Cause the iron mold to slip out of the positioning position, disturb the normal operation of the production line, and figure 1 Middle: There is an offset between the blocking iron signal and the rushing signal

The patent frame includes a top box and a column connected to the bottom of the top box. The bottom of the top box is provided with a sand-covered cover, and a support roller table is provided under the sand-covered cover for sand-covered molding. The iron type in it plays the role of locating the iron type and accumulating the iron type. Obviously, the function and content structure cannot be compared
