The utility model discloses to little sand mould, the workman can directly remove the printer work box through hand digging to the sand mould body, avoids digging sand mould body bottom and removes the sand mould body and leads to being pressed in one's hands; 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.

Description

Casting 3D printing sand mold

Technical Field

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

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, when stripping is finished in printing, since no supporting point capable of being grasped is reserved on the outer circular surface of the sand mold, a worker can only take out the sand mold body from a printer case by picking the bottommost surface of the sand mold body by hand, and the risk that fingers are crushed by the sand mold body exists; when a large sand mold is encountered, even a plurality of workers are needed to carry out the sand mold simultaneously, so that the labor intensity of the workers is increased.

SUMMERY OF THE UTILITY MODEL

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

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

as preferred, a casting 3D prints sand mould, including the sand mould body, its characterized in that: the sand mould body adopt and pile up the setting from top to bottom in proper order, every outer disc of sand mould body all the annular be provided with a plurality of groups recess, sand mould body side bilateral symmetry be provided with two sets of lifting eyes.

Preferably, the grooves are of rectangular structures, and are arranged in parallel on each layer of the sand mold body and are positioned on a straight line.

Preferably, the lifting holes are arranged on two sides of the sand mold body in parallel and symmetrically.

Preferably, the lifting hole is provided in the sand mold body in a penetrating manner.

Preferably, one end of each lifting hole is located between two adjacent grooves, and the other end of each lifting hole is located between two adjacent grooves.

The utility model has the advantages that for the small sand mold, a worker can directly move the sand mold body out of the printer work box through hand picking, and the bottom of the sand mold body is prevented from being pressed to one hand due to the fact that the sand mold body is moved; 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.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate the position or positional relationship based on the position or positional relationship shown in the drawings, or the position or positional relationship which is usually placed when the product of the present invention is used, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.

Furthermore, the terms "horizontal", "vertical", "overhang" and the like do not imply that the components are required to be absolutely horizontal or overhang, but may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in FIG. 1, the embodiment of the present invention is

The utility model provides a casting 3D prints sand mould, includes sand mould body 1, its characterized in that: the sand mold body 1 is sequentially stacked up and down, a plurality of groups of grooves 3 are annularly formed in the outer circular surface of each layer of the sand mold body 1, and two groups of lifting holes 2 are symmetrically formed in the side surface of the sand mold body 1 in the left-right direction; the grooves 3 are of rectangular structures and are arranged in parallel on each layer of the sand mold body 1 and are positioned on a straight line; the lifting holes 2 are arranged on two sides of the sand mould body 1 in parallel and symmetrically; the lifting holes 2 are arranged in the sand mould body 1 in a penetrating manner; one end of each lifting hole 2 is positioned between two adjacent grooves 3, and the other end of each lifting hole 2 is positioned between two adjacent grooves 3.

In the specific implementation:

a groove 3 with the length of 100mm, the height of 40mm and the depth of 40mm is dug on the side surface of the sand mold body 1 and is used as a hand-picking tool during stripping; through respectively opening a through hole 2 with the diameter of 40mm on both sides of the sand mould body 1, a steel pipe is inserted into the through hole 2 and used for lifting the mould.

For small sand molds, workers can directly move the sand mold body 1 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 1 is moved at 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 1 through the lifting holes 2, so that the labor intensity of the worker is greatly reduced.

The above, only do the preferred embodiment of the present invention, not used to limit the present invention, all the technical matters of the present invention should be included in the protection scope of the present invention for any slight modification, equivalent replacement and improvement of the above embodiments.
