Abstract
The invention discloses a connecting structure for a sand box body and a box cover. The connecting structure comprises the box body and the box cover, wherein bolt via holes opposite to bolt via holes on convex plates at a lower port of the box cover are formed in convex plates at an upper port of the box body, and nuts are matched with threads of bolts. Compared with the prior art, the connecting structure has the advantages of low labor intensity and stable and reliable connection.
Description
Technical field:
The present invention relates to a kind of casting sandbox, the particularly syndeton of sandbox casing and case lid.
Background technology:
Foundry goods is blank commonly used in the machinery, consumption is very large, and foundry goods is in casting cycle, because the weight of molten iron and its coefficient of expansion are larger, can cause case lid by jack-up, the lighter's casting deformation and plate are useless, and the overflow of severe one molten iron is accidents caused, for avoiding moving the defects that causes on the case lid, existing measure is to place weight at case lid, and weight leans on workman's experience, the shortcoming of this scheme to be, labour intensity is large and efficient is low.
Summary of the invention:
The purpose of this invention is to provide a kind of labour intensity is low, efficient is high and safe and reliable sandbox casing and the syndeton of case lid.
The technical scheme that realizes the object of the invention is, the syndeton of sandbox casing and case lid, comprise casing and case lid, it is characterized in that: be provided with the relative bolt through-hole of bolt through-hole on the outer flange with the case lid lower port at the outer flange of casing upper port, the screw thread of nut and described bolt matches.
The present invention has advantages of that compared with the prior art labour intensity hangs down and firm and reliable connection.
Description of drawings:
Fig. 1 is structural representation of the present invention.
The specific embodiment:
In conjunction with above-mentioned accompanying drawing the present invention is elaborated, be provided with the relative screw via hole of screw via hole on the outer flange 3 with case lid 4 lower port at the outer flange 2 of casing 1 upper port, bolt 5 is through at above-mentioned casing port evagination plate and the outer flange screwing via hole of case lid port, and nut therewith bolt matches.The quantity of above-mentioned bolt is uniform a plurality of along the wall of casing according to the size of sandbox specification.
Method of operating of the present invention: when pouring molten iron, at first with bolt case lid is fixed on the upper end of casing after, just can carry out pouring molten iron, at first back out the nut of bolt when getting foundry goods, remove bolt after, can remove case lid and take out foundry goods.
