Description

Casting 3D printing sand mold locking device

Technical Field

The utility model relates to a 3D prints sand casting field, concretely relates to casting 3D prints sand mould locking device.

Background

At present, with the gradual industrialization of the 3D printing technology, a method for casting and producing by using a 3D printing sand mold is widely used. The 3D technology can realize high-precision printing of various sand cores with complex structures, and the problems of mold stripping and material withdrawal in the traditional process are not required to be considered, so that the process method is suitable for production of castings with various complex structures.

In the prior art, the weight placed on a sand mold in the sand mold pouring process is required to be 3-5 times of the pouring quality, and if the pouring quality is close to 1 ton, the weight to be placed exceeds the quality of the sand mold, so that the labor intensity of the operation of workers is high.

SUMMERY OF THE UTILITY MODEL

To the above problem, the utility model aims at providing a casting 3D prints sand mould locking device.

In order to realize the technical purpose, the utility model discloses a scheme is:

as preferred, a casting 3D prints sand mould locking device, including the sand mould body, its characterized in that: the sand mould body include mould and lower mould, the outer ring of mould and lower mould evenly be provided with a plurality of groups recess, last mould and lower mould excircle both sides around run through the symmetry and be provided with the lifting eye, last mould circular symmetry all around be provided with a plurality of groups arc recess, last mould and lower mould circular symmetry all around be provided with the bolt hole that a plurality of groups run through, bolt hole bottom be provided with the reservation tank.

Preferably, the arc-shaped groove is communicated with the bolt hole.

Preferably, the bolt hole can be either a dug-in type or an extended type.

The utility model has the advantages that:

1. the area for installing the mold locking device is dug or grown on the mold, so that the quality of the weights required to be placed on the sand mold can be reduced, and the labor intensity of workers is reduced.

2. For small sand molds, workers can directly move the sand mold body out of a printer work box through hand picking, and the situation that the hand is pressed due to the fact that the sand mold body is moved from the bottom of the sand mold body is prevented from being picked; for a heavier sand mold, a worker can hang out the sand mold body through the lifting hole, so that the labor intensity of the worker is greatly reduced.
