Embodiment Construction

[0032] 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.

[0033] Such as Figure 1 to Figure 6 Shown, a kind of method for sand unloading treatment after casting casting molding, comprises the following production steps:

[0034] Step 1: Casting molding process, injecting molten metal into the sand box with the mold, wait until the molten metal is solidified, and obtain the casting sand box;

[0035] In step 2, the molding sand is drilled and dropped, and the casting sand box obtained in step 1 is passed through the drill bit mechanism 31, and the molding sand in the sand box is drilled and dropped to obtain the residual molding sand flask;

[0036] In step 3, the molding sand is vibrated and scattered, and the residual molding sand box obtained in step 2 is vibrated and sand-cleaned to obtain an empty sa...

Abstract

The invention relates to a sand discharging treatment method used after the casting molding of castings. The method mainly comprises the following procedures of casting molding treatment, molding sanddrilling-off treatment, molding sand ramming treatment, casting fetching treatment, casting stacking treatment and the like. The following problems, namely that a, in the process that molding sand iscleared by adopting a common manual sand clearing mode after the casting of the castings is finished, high worker labor intensity, incomplete sand clearing and inconvenient casting fetching result from firm molding sand bonding and difficult manual clearing, and b, in the process that the molding sand is cleared after the casting of the castings is finished, the existence of molding sand residuesin a sand box after sand clearing causes the following difficult repeated use of the sand box and the increase of clearing cost, which occur in the existing casting processing process, can be solved.

Description

technical field [0001] The invention relates to the technical field of casting processing, in particular to a method for unloading sand after casting of castings. Background technique [0002] Casting is a method in which liquid metal is poured into a casting cavity adapted to the shape of the part, and after it is cooled and solidified, the part or blank is obtained. The material to be cast is mostly a metal that was originally solid but heated to a liquid state (for example: copper, iron, aluminum, tin, lead, etc.), and the material of the mold can be sand, metal or even ceramics. [0003] The main steps of casting are divided into: mold production, sand mixing stage, modeling stage, melting stage, pouring stage, cleaning stage and other steps. [0004] The following problems exist in the processing of existing castings, a. In the process of cleaning the molding sand after the casting is finished, the method of manual sand cleaning is usually adopted, the molding sand is ...
