Embodiment Construction

[0036] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0037] Such as Figure 1 to Figure 9 As shown, a molding sand casting demolding treatment method, which uses a flipping discharge device, the flip discharge device includes a bottom plate 1, a support frame 2, a discharge mechanism 3 and a collection box 4, using the above flip discharge device The specific method for demoulding processing is as follows:

[0038] S1. Equipment adjustment: make adaptive adjustments to the size of the corresponding parts of the turning and discharging device according to the actual size of the sand box;

[0039] S2. Fixing the sand box: manually fix the sand box on the discharge mechanism 3;

[0040] S3, reciprocating flipping: through the discharge mechanism 3, the opened sand box is driven to turn back and forth, ...

Abstract

The invention provides a sand casting demolding treatment method. According to the sand casting demolding treatment method, a turnover discharging device is included, and the turnover discharging device comprises a bottom plate, a support frame, a discharging mechanism and a collecting box. The method for carrying out demolding treatment operation by using the turnover discharging device specifically comprises the steps of equipment adjustment, sand box fixing, reciprocating overturning, taking out of a casting and cleaning of the casting. The discharging mechanism comprises an overturning motor, an overturning bracket, a positioning seat, a positioning rod, a vertical plate, a jacking block and a protective branch chain. The protective branch chain comprises a fixing plate, a limiting rod, a connecting screw rod, a rotating plate, a butt-joint screw rod, a transverse stop rod, a longitudinal stop rod and an extrusion frame. After a sand box is fixed on the discharging mechanism, sandis made to continuously fall off from the sand box in a reciprocating overturning mode, in the overturning process, the casting can be protected by the protective branch chain, and the situation thatthe casting is thrown out and is thus scratched is avoided.

Description

technical field [0001] The invention relates to the field of casting, in particular to a mold-sand casting demoulding treatment method. Background technique [0002] Sand mold casting is a widely used casting form, which is to use sand to make molds. Sand mold casting needs to put the finished part model or wooden model in the sand, and then fill the sand around the pattern. After taking out the pattern from the box, the sand forms a mold, and then pours the metal liquid into the mold through the pouring system, and waits for the metal liquid to solidify. castings can be produced. [0003] After the casting is formed, the molding sand in the sand box needs to be poured out to take out the casting. At present, the cleaning of the molding sand is mainly done by turning the sand box manually. This method has the following problems in the actual operation process: [0004] (1) The overall mass of the sand box is large, and the staff consumes a lot of physical strength during t...
