Embodiment Construction

[0007] A kind of sand-cleaning device for iron mold shot holes in iron mold sand covering process, such as figure 1 As shown, it includes base plate 1, ejector rod distribution plate 2, pad cover 3, screw 4, ejector rod 5, spring 6 and iron type 7, base plate 1, ejector rod distribution plate 2, and pad cover 3 are connected by screws 4, and the base plate 1 is set above the ejector pin distribution plate 2, and the pad cover 3 is set between the bottom plate 1 and the ejector pin distribution plate 2. The pad cover 3 is used to adjust the gap between the bottom plate 1 and the ejector pin distribution plate 2. There is a circular through hole consistent with the sand shooting hole on the iron type 7, and the ejector rod 5 is arranged in the circular through hole on the ejector rod distribution plate 2, and the gap between the ejector rod 5 and the circular through hole is 1mm; The upper end of the rod 5 is provided with a circular hole, and the spring 6 is arranged in the cir...

Abstract

The invention relates to a cleaning device of an iron mould sand-covering process iron mould sand ejecting hole. A base board (1), an ejector rob distribution board (2) and a cushion sleeve (3) are connected through bolts (4), the base board (1) is arranged above the ejector rob distribution board (2), the cushion sleeve (3) is arranged between the cushion sleeve (3) and the base board (1), a circular through hole is arranged on the ejector rob distribution board (2), an ejector rob (5) is arranged in the circular through hole, a circular hole is arranged at the upper end of the ejector rob (5), a spring (6) is arranged in the circular hole at the upper end of the ejector rob (5), the upper end of the spring (6) is connected with the base board (1), an iron mould (7) is arranged below the ejector rob distribution board (2), and the sand ejecting hole on the iron mould (7) right faces to the circular through hole on the ejector rob distribution board (2). The ejector rob of the device is in flexible connection with the ejector rob distribution board, the device can be applicable to various changes of positions of the sand ejecting hole at different temperature, breaking rate of the ejector rob can be effectively reduced, normal use of cleaning equipment is guaranteed, and production efficiency is improved.

Description

technical field [0001] The invention relates to an iron mold sand-coated mold, in particular to a sand cleaning device for iron mold sand-shooting holes in the iron mold sand-coating process. Background technique [0002] The casting of the nodular cast iron crankshaft adopts the iron mold sand-covering process, and the iron mold sand cleaning uses sand cleaning equipment. Since the iron mold is in a hot state when used, the ejector pin and the ejector pin distribution of the sand shooting hole will be cleaned during sand cleaning tooling. The plates are rigidly connected with threads. When the iron mold is heated and elongated, the position of the sand shooting hole changes, but the ejector rod distribution plate is not heated, and the position of the ejector rod does not change correspondingly to the position of the sand shooting hole. When the sand hole is sanded, the ejector pin is broken, so that the sand cleaning equipment cannot be used normally, and it is necessary t...
