Abstract
The utility model relates to a three-layer sand box for foundry casting for a copper furnace. The sand box comprises an upper-layer casting box and a lower-layer casting box, wherein the lower-layer casting box is positioned below the upper-layer casting box, and a middle-layer casting box is arranged between the upper-layer casting box and the lower-layer casting box of the sand box and is of a split structure. The three-layer sand box provided by the utility model can be used for casting various types of copper wares and is particularly suitable for casting symmetric copper wares, the application range is wide, the production cycle of copper castings is speeded up, and the demoulding casting problem of three-dimensional and complex copper wares is solved. The low cost of appliances and materials is favorable for substantially reducing the production cost of copper furnace casting, the success rate of copper furnace casting can reach 90% above, and the production efficiency is substantially improved.
Description
Technical field
The utility model relates to a kind of improvement of foundry casting sandbox, relates in particular to a kind of copper stove foundry casting three-part flask.
Background technology
Tradition foundry casting technique sandbox used is 2 layers of up and down, and this sandbox can not be used for the founding foundry goods of three-dimensional and complicated type.After the back-up sand of shape mould, can only upwards pull out the shape mould, in this case, it is symmetrical that the shape die topography must satisfy the center line horizontal and vertical simultaneously, otherwise can't keep taking out the shape mould in the indeformable situation of sandbox internal shape cavity.Foundry casting is used for coin and bronze mirror casting in ancient times, but never is used for the casting of the complicated and three-dimensional type such as copper stove.Main cause is, founding in ancient times sandbox used is 2 layers of up and down, is subjected to the restriction of die joint, only can be used for the casting of simple flat type, and the ejection technique of the three-dimensional types such as copper stove does not solve in ancient times, so foundry casting can not be used for the production of copper stove.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and a kind of copper stove foundry casting equipment that is applicable to is provided.
The purpose of this utility model is to adopt following technical scheme to realize:
A kind of copper stove foundry casting three-part flask, described sandbox has upper strata molding box and lower floor's molding box, lower floor's molding box is positioned at the below of upper strata molding box, it is characterized in that: be provided with the middle level molding box between the upper strata molding box of described sandbox and lower floor's molding box, this middle level molding box is split-type structural.
Described middle level molding box has two symmetrically arranged minute molding boxes.
Described upper strata molding box, lower floor's molding box and middle level molding box are respectively equipped with door handle device.
The copper stove foundry casting three-part flask that the utility model provides, increased the middle level molding box, sandbox is divided into the design of upper, middle and lower-ranking molding box, and the intermediate layer molding box can be split to both sides by the sandbox middle part, in knockout course, can pull to the relative both sides of horizontal direction two symmetrically arranged minute molding boxes, this operation makes sandbox can be used for the demoulding that outer wall is irregular, curvature and three-dimensional shape shape mould are arranged.Owing to can pull open sandbox after moulding to horizontal direction, thereby make the shape chamber in sandbox can keep moulding original shape, and easily take out the shape mould after pulling open sandbox.Thereby solved the demoulding casting problem of three-dimensional and complicated type.
The copper stove foundry casting sandbox that the utility model provides can be used for the bronze, brass or copper ware casting of various types, is particularly useful for the bronze, brass or copper ware casting of symmetrical type, has wide range of applications, and has accelerated the copper casting production cycle.Tradition lost-wax process casting copper stove overall process needs 20 days, and after the foundry casting that employing the utility model provides, the casting process of copper stove can shorten to 3 days.The utility model casting technique apparatus used and lower cost for material help significantly to reduce the production cost that the copper stove is cast, and copper stove casting success ratio can reach more than 90%, has significantly improved production efficiency.

The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described:
See also shown in Fig. 1, figure, the present embodiment three-part flask is comprised of upper strata molding box 1, middle level molding box 2 and lower floor's molding box 3, upper strata molding box 1, middle level molding box 2 and lower floor's molding box 3 are made by aluminum alloy material respectively, and each layer volume is respectively: the high 36cm of the wide 25cmX of long 30cmX, each floor height 12cm.During use, upper strata molding box 1, middle level molding box 2 and lower floor's molding box 3 be overlapping combining successively from top to bottom.Middle level molding box 2 is split-type structural, in the present embodiment, middle level molding box 2 is combined by two symmetrically arranged minute molding boxes 21 and 22, and minute molding box 21 is identical with 22 shapes, be open to the left or to the right cavity during horizontal positioned, will divide molding box 21 and 22 symmetries to be bolted together during use and get final product.
For convenience of operation, upper strata molding box 1, middle level molding box 2 and lower floor's molding box 3 can arrange respectively door handle device, and the present embodiment is provided with handle 4.
Copper stove foundry casting technique based on above-mentioned copper stove foundry casting three-part flask comprises the steps:
(1) with lower floor's molding box 3 horizontal positioned, the shape mould of the copper casting of needs castings is placed in the middle of lower floor's molding box 3, then insert back-up sand in lower floor's molding box 3 and compress real, strike off, lower floor's molding box 3 is made complete;
(2) evenly lay the thin layer tap sand on lower floor's molding box 3 that above-mentioned steps (1) is completed, two minutes molding box Symmetric Composites of middle level molding box 2 are placed on lower floor's molding box 3, insert back-up sand again in middle level molding box 2, and compress real, strike off, complete middle level molding box 2 and make;
