Abstract
The utility model discloses a mold capable of realizing a novel casting process, which comprises a sand box, an upper mold and a lower mold with a bottom mold cavity, wherein the upper mold can form a top mold cavity in the sand box through resin sand fixation, the top mold cavity can be spliced and communicated with the bottom mold cavity, the lower mold is made of metal, so that the solidification sequence from bottom to top is facilitated, the quality of a casting is ensured, the surface quality of the casting is high, and the internal structure is compact.
Description
Technical Field
The utility model relates to a mold, in particular to a mold capable of realizing a novel casting process, and belongs to the field of casting.
Background
The sand mould process has no special requirements on the structure of the casting, and is particularly superior to other casting process modes due to the complex structure and the thick wall and large wall thickness. For heavy mining machinery cylinder aluminum alloy casting, it is extremely high to the leakproofness requirement, but at present mainly adopt traditional sand casting to heavy mining machinery cylinder aluminum alloy casting sealed face, place the chill chilling at its sealed face (promptly the sealed face described in this application), because the chill absorbs the heat limited, sealed face quality improves limitedly, and sealed face machined back surface has a lot of intensive tiny holes, and the production efficiency of sand mould technology can't satisfy customer's demand. For parts with extremely thick wall thickness, the metal mold gravity casting process is adopted, the mold chilling is strong, the surface of the casting is solidified too fast, and effective means cannot be adopted to supplement the casting to cause internal shrinkage porosity, so that the casting scrapping cannot meet the use requirement.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems in the prior art, the utility model provides the die which has the technical characteristics of simple structure, strong practicability, high casting quality and the like and can realize a novel casting process.
In order to achieve the purpose, the utility model is realized by the following technical scheme:
the utility model provides a can realize mould of novel casting process, includes sand box, cope match-mould and the bed die that has bottom model chamber, the cope match-mould can be formed with top model chamber through the resin sand fixed telephone in the sand box, top model chamber can be with bottom model chamber amalgamation and intercommunication, the bed die is the metal.
Preferably, the profile of the lower die is a metal of QT 500.
Preferably, a channel hole is formed in the top model cavity, a cold iron loose piece 4 is arranged on the inner wall of the channel hole, and the cold iron loose piece can be assembled and connected with the lower die.
Preferably, the contact position of the lower end surface of the top model cavity and the upper end surface of the bottom model cavity is a sealing surface of a cast casting.
Has the advantages that: the solidification sequence from bottom to top is facilitated, the quality of the casting is guaranteed, the surface quality of the casting is high, and the internal structure is compact.

FIG. 2 is a cross-sectional view of the utility model A-A.
Detailed Description
The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following examples.
Fig. 1-2 show a specific embodiment of a mold capable of implementing a novel casting process, which includes a sand box 1, an upper mold and a lower mold 3 with a bottom mold cavity, wherein the upper mold is capable of forming a top mold cavity 2 in the sand box 1 by resin sand fixation, the top mold cavity 2 is capable of being spliced and communicated with the bottom mold cavity, and the lower mold 3 is made of metal.
The novel metal mold casting device is simple in structure, complex process tool requirements are not needed, sand casting and metal mold casting are creatively combined, the feeding requirements of sand casting castings are met, and the high efficiency and the high internal quality of metal molds are also met.
Specifically, the method comprises the following steps: the upper half casting mould section is resin sand, a top mould cavity 2 is formed through resin sand fixation, the lower half casting mould is directly formed section which is QT500 metal, the top mould cavity 2 is matched with the bottom mould cavity, and the structure of the sealing surface 5 is compact by adopting the composite casting process form (the characteristics of metal casting are utilized, namely the efficiency is high, the surface quality of the casting is high, and the internal structure is compact).
The principle of the application is as follows: the top model cavity 2 of the upper half-casting type section is resin sand, the heat dissipation speed of the top model cavity is lower than that of the top model cavity 2 made of the lower half-casting type metal material, so that a temperature gradient that the temperature of the upper casting type is high and the temperature of the lower casting type is low is formed, the solidification sequence from bottom to top is facilitated, and the casting quality is guaranteed. The upper casting molds with a certain number can be manufactured according to production arrangement, the efficiency is greatly improved, process tools are almost not required to be adjusted, the qualified rate of castings is obviously improved, and the economic benefit is high.
In a preferred embodiment, the profile of the lower die 3 is a metal of QT 500.
In a preferable embodiment mode, a channel hole is formed in the top model cavity 2, a cold iron loose piece 4 is arranged on the inner wall of the channel hole, and the cold iron loose piece 4 can be assembled and connected with the lower die 3, so that the top model cavity 2 is conveniently matched with the bottom model cavity of the lower die 3.
In a preferable embodiment mode, the contact part of the lower end surface of the top model cavity 2 and the upper end surface of the bottom model cavity is a sealing surface 5 for casting a casting, and by adopting the composite casting mode, the characteristics of high efficiency, high casting surface quality and compact internal structure of a metal mold are utilized, so that the structure of the sealing surface 5 of the final casting is compact.
Finally, it should be noted that the present invention is not limited to the above embodiments, and many variations are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the present invention are to be considered within the scope of the utility model.
