Problems solved by technology

However, if the casting speed is too fast or too slow during the casting process, it will have a great impact on the real casting, which will affect the quality of the casting.

Embodiment Construction

[0014] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] like Figure 1 to Figure 3 As shown, a kind of solid casting mold provided by the present invention includes an upper mold 1 and a lower mold 2. When casting, the foam model is filled in the lower mold 2, and is tamped and buried with glass sand, and the upper mold 1 is closed and cast forming. The upper mold 1 is provided with a sprue cup 3, a casting channel 4 and a riser 5, the sprue cup 3 is funnel-shaped, and the lower end of the sprue cup 3 is connected with the casting channel 4, and the casting channel 4 can be a sprue , can also be other forms of channels, here we take the sprue as an example for specific description. A connecting pipe 6 is arranged above the sprue cup 3, and the connecting pipe 6 is fixedly connected with the upper mold 1. A horizontal plate 7 is erected above the connecting pipe 6, and the horizontal plate 7 is co...

Abstract

The invention specifically relates to a solid casting mold, which includes an upper mold and a lower mold. The upper mold is provided with a sprue cup, a casting channel and a riser. The sprue cup is funnel-shaped, and the lower end of the sprue cup is in contact with the casting The channel is connected, and a connecting pipe is provided above the sprue cup, and the connecting pipe is fixedly connected with the upper mold. A horizontal plate is erected above the connecting pipe, and the horizontal plate is connected with the connecting pipe through bolts. There is a threaded hole on the horizontal plate. , a screw is provided in the threaded hole, the axis of the screw coincides with the axis of the sprue cup, and a flow limiting block is provided at the lower end of the screw, and the flow limiting block is matched with the sprue cup. An additional mold is arranged on the upper mold, and an additional riser is arranged in the additional mold. The flow limiting block is adjusted by turning the screw to control the casting speed of the casting liquid, thereby ensuring the molding quality of the casting. When the size of the casting is large, increasing the riser can fully supplement the shrinkage of the casting when it is finally solidified, so as to ensure the quality of the casting.

Description

technical field [0001] The present invention relates to the technical field of full mold casting, in particular to a full mold casting mold, comprising an upper mold and a lower mold, the upper mold is provided with a sprue cup, a casting channel and a riser, and the sprue cup is funnel-shaped , the lower end of the sprue cup communicates with the casting channel. Background technique [0002] The full mold casting adopts the polystyrene foamed plastic pattern instead of the ordinary wooden mold. After the mold is made, the mold is not taken out, and the molten metal is directly poured into it. Under the action of ordinary molten metal, the plastic pattern burns, vaporizes, and disappears. The molten metal replaces the space occupied by the original plastic film, and the required casting is obtained after cooling and solidification. Full mold casting has obvious advantages, simplifies the production process, reduces the cost of castings, shortens the production cycle, and i...
