As preferably, described wedge is one piece, and the bottom surface of described wedge is horizontally disposed with, and the top surface inclination of described wedge is arranged, and after installation, the end face of described wedge is compressed by described upper pinching end, or, described wedge is two pieces, i.e. the first wedge and the second wedge, the bottom surface of the first described wedge and the second described wedge is all horizontally disposed with, the end face of the first described wedge and the second described wedge is all obliquely installed, the oblique angle of the end face of the first described wedge differs 0.5 ~ 10 ° with the oblique angle of the end face of the second described wedge, after installation, first wedge and the second wedge mounted on top, the end face of the first wedge leans on mutually with the end face of the second wedge, upper flange limit described in upper pinching end described in the first wedge stacked and the second wedge coordinate compresses.One piece of wedge, is convenient to be knocked in by this wedge hammer in the gap between the upper surface on upper pinching end and upper flange limit, this wedge of abate in the other direction when being simultaneously convenient to dismantle.When one piece of wedge insufficient height, polylith wedge can be stacked use, the quantity of wedge preferably two pieces, i.e. the first wedge and the second wedge, and guarantee that the oblique angle of the end face of the first wedge differs 0.5 ~ 10 ° with the oblique angle of the end face of the second wedge, first wedge and the second wedge are mutually struck like this tightly, both relative fastnesses are strong, effectively can avoid the mutual slippage in use procedure.
As preferably, described locking clamp is shaping by cast iron integrally casting, can reduce the cost of manufacture of retaining mechanism further.
As preferably, the both sides of described locking clamp are respectively provided with a groove, and one end of each described groove is connected with described upper pinching end, and the other end is connected with described lower pinching end.Groove reduce locking clamp materials while, the Stress Release of retaining mechanism in process easy to use.
As preferably, described locking clamp entirety is C type.
Compared with prior art, the utility model has the advantage of: the locking mechanism structure of the utility model disclosed casting sandbox is simple, with low cost, easy accessibility, laborsaving, can labor strength be alleviated, save man-hour, increase work efficiency; Consume little in this retaining mechanism use procedure, can Reusability, avoid the impact of sandbox flange intensity and the adhesion phenomenon that produces because molten metal drippage simultaneously; For a set of casting sandbox, quantity and the locked position of locking unit in retaining mechanism can be selected flexibly, convenient and practical.
