Center casting type production system for manually casting ACE line

Technical Field

The utility model belongs to the technical field of casting, and particularly relates to a center casting type production system for manually casting an ACE line.

Background

An ACE static pressure automatic molding line is one of automatic production lines. A casting ladle of the manual casting ACE line is hoisted by a crown block in a factory building to inject soup, the side part of a sand box is opposite to a soup injection port of the casting ladle, and casting materials enter a sand mold of the sand box from the soup injection port on the upper side part of the sand box. At present, a pouring gate serving as a casting production system in a sand mold comprises a sprue channel extending downwards at the side part of the sand mold, a horizontal sprue hole extending transversely and communicated with the lower end of the sprue channel is formed in a sand box, a plurality of casting cavities are distributed in the sand box in a straight line and in a double row at two sides of the horizontal sprue hole, and the horizontal sprue hole is communicated with the casting cavities through branch pouring gate holes. The pouring gate system of the manual casting ACE line in the traditional mode is large in whole length of a pouring gate hole, high in waste material yield and waste in materials, and is not beneficial to environmental protection. Because the distance between the casting cavity and the sprue is different, the quality of the formed casting is difficult to unify. The crown block which is matched with the ACE for working is manually cast, the position of the crown block in a factory building is fixed, the position is difficult to modify, and the method for overcoming the problems by changing the position of pouring soup is difficult to realize.

The utility model has the advantages and effects that:

according to the center casting type production system for manually casting the ACE line, disclosed by the utility model, the casting cavity is annularly arranged by taking the vertical center pouring channel hole as a center, and the casting material in the ladle of the manually casting ACE line is guided to the vertical center pouring channel hole by the transverse pouring channel at the upper end part of the sand mold, so that the center casting mode is realized in the manually casting ACE line, and the complicated equipment structure in a production line is not required to be modified. Compare the casting system of traditional double in-line mode foundry goods die cavity, this system not only can reduce the waste material production volume, avoids extravagant, reduces environmental pollution, and the quality of foundry goods is unified, and product quality is high.

On the other hand, the sprue gate at the upper part of the transverse pouring gate in the system is of a closing-up structure, so that the condition that casting materials with large weight are splashed outwards when falling into the transverse pouring gate can be effectively avoided, the casting quality is ensured, and meanwhile, the waste is further avoided.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

In order to solve the problems of material waste and environmental pollution of the conventional manual casting ACE line, the utility model particularly provides a central casting type production system for the manual casting ACE line, which can reduce the casting material waste, reduce the environmental pollution and improve the product quality. To further illustrate the structure of the present invention, the following detailed description is made with reference to the accompanying drawings:

referring to fig. 1-3, a center casting type production system for manually casting an ACE line includes a sand mold. As is well known to those skilled in the art of foundry practice, a sand mold is a casting mold made of sand. The sand mold casting requires placing a finished part mold or a wooden mold in sand, filling the sand around the pattern, opening the box and removing the pattern to form a mold.

The sand mould has horizontal runner 1, and horizontal runner 1 is located sand mould up end and transversely extends to the sand mould middle part from the sand mould lateral part. The transverse runners 1 are open-ended flow channels for the flow of liquid casting material.

The end part of the transverse pouring gate 1 close to the edge of the sand mould is provided with a soup pouring port 1-1, the position of the soup pouring port 1-1 is opposite to the blanking port of a ladle of a manual casting ACE line, the ladle of the manual casting ACE line is hung by a crown block, and the crown block hangs the ladle to the soup pouring position.

The other end of the transverse pouring gate 1 is communicated with a vertical central pouring passage hole 2 which vertically extends downwards in the sand mould, and the vertical central pouring passage hole 2 is a vertical circular hole passage and is positioned in the sand mould. The liquid casting material guided by the transverse pouring gate 1 enters the sand mould from the vertical central pouring gate hole 2.

The lower end of the vertical central runner hole 2 is connected with a plurality of branch runner holes 3 which are distributed radially, each branch runner hole 3 is communicated with a casting cavity 4, and the casting cavities 4 are distributed circumferentially by taking the vertical central runner hole 2 as the center. The casting cavity 4 can be provided with a sand core on the inner side according to the requirement of the casting. The sand mould is also provided with a riser with an opening at the upper end communicated with the casting cavity 4. The liquid casting material in the vertical central runner hole 2 is drained from the branch runner hole 3 to each casting cavity 4. Compared with the horizontal runner hole extended in a traditional horizontal straight line, the vertical central runner hole 2 is greatly shortened in length, so that waste materials generated after the central runner hole is cast are reduced.

The upper part of the transverse pouring gate 1 is a transversely extending gate opening 1-2, two sides of the gate opening 1-2 extend inwards, and the side wall of the transverse pouring gate 1 close to the gate opening 1-2 forms a concave structure. Namely, the sprue gate 1-2 is an inward-closing structure with two sides extending inwards, and the cross section of the inner side surface of the horizontal sprue gate 1 is arc-shaped. The liquid casting material falls into the transverse pouring gate 1 from the soup pouring port 1-1 of the transverse pouring gate 1 and is guided by the transverse pouring gate 1, namely, the closing-up structure of the pouring gate port 1-2 enables the liquid casting material to be inwards splashed under the guiding action of the arc-shaped side surface in the transverse pouring gate 1, so that the liquid casting material is completely prevented from being splashed to the outer side of the transverse pouring gate, the liquid casting material can stably flow in the transverse pouring gate, and the casting quality is improved to a certain extent.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
