Detailed Description

In order to explain the technical content, the objects and the effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.

Referring to fig. 1 to 4, the casting forming device based on molten steel according to the present invention includes a horizontally disposed base 1, and a liquid injection pipe 2 and a forming mold 3 vertically disposed on the base 1, respectively; and the horizontal height of the topmost end of the liquid injection pipeline is higher than the horizontal height of the topmost end of the forming die.

In this embodiment, base 1 is squarely, annotate liquid pipeline 2 and be located the base corresponds square central point and puts the setting, forming die 3's quantity is eight, and eight forming die 3 encircle respectively and annotate liquid pipeline 2 periphery and evenly arrange.

It should be noted that, because the casting formed by the molten steel is bulky and heavy, the base and the liquid injection pipeline are made of steel, so as to improve the structural strength of the base and the liquid injection pipeline, and in order to avoid the reaction between the molten steel and the base or the liquid injection pipeline, the channel pile made of argil is used as the molten steel conveying pipeline in the following process.

Promptly annotate 2 upper ends of liquid pipeline and be equipped with into the liquid mouth, it is equipped with the liquid outlet to annotate 2 lower tip of liquid pipeline, 3 lower tip of forming die are equipped with opening 31, 1 upper surface of base is equipped with runner 4, runner 4's quantity is eight, and distributes with "rice" font, annotate liquid pipeline 2 and correspond "rice" font central point and put the setting, eight forming die 3 corresponds eight free end tip position settings of "rice" font.

One end of each of the eight flow passages 4 is communicated with the liquid outlet, and the other end of each of the eight flow passages 4 is communicated with the corresponding opening 31 of the forming die 3.

Specifically, argil pipe fittings 5 are laid inside the liquid injection pipeline 2 and inside the flow channel 4, the argil pipe fittings 5 are formed by sequentially splicing multiple sections of argil channel piles 51, and in the actual design process, gaps between the outer side walls of the argil pipe fittings and the inner side walls of the liquid injection pipeline or the inner side walls of the flow channel are required to be as small as possible, so that the argil channel piles are not prone to shifting in the molten steel injection process, and the sealing performance of the liquid injection pipeline is ensured. In particular, through holes are respectively arranged at the two axial ends of the liquid injection pipeline of the pottery clay channel pile positioned in the middle of the liquid injection pipeline, a convex edge 52 which protrudes along the axial direction is arranged at the through hole at one end, and a step 53 which is formed by sinking along the axial direction and is matched with the convex edge is arranged at the through hole at the other end. The design can further improve the assembly stability among the clay channel piles.

The liquid inlet is a horn mouth with a large upper part and a small lower part, a horn-shaped pottery clay pipe fitting is laid on the inner wall of the horn mouth, and the pottery clay pipe fitting at the liquid inlet is butted with the pottery clay pipe fitting inside the liquid injection pipeline. The pottery clay pipe fitting is adopted, firstly, the pottery clay pipe fitting has the characteristic of high temperature resistance and is suitable for a molten steel environment, and secondly, the direct contact between molten steel and a liquid injection pipeline and the inner wall of a flow passage is isolated, so that the structural performance is influenced.

In this embodiment, the upper end surface of the forming mold 3 is an opening 32, the size from the upper end surface to the lower end surface of the forming mold 3 is gradually smaller, before the casting is formed, the anti-adhesion agent is firstly adhered to the inner surface of the forming mold, and a side plate 33 made of clay material is disposed on the inner side wall of the opening of the forming mold and surrounds the opening. During the drawing of patterns, the hoist and mount that adopt earlier on the portal frame is fixed with the last lug 34 installation that is located the top on the forming die lateral wall, can carry, and the transport is regional to the drawing of patterns, and the regional shop front of drawing of patterns is thick sand bed. And then the side plate is pulled out, the hoisting on the portal frame and the lower lug 35 positioned below the outer side wall of the forming mold are adopted to be installed and fixed, the forming mold can be reversely buckled, and the casting can be separated from the mold to complete demolding. When molten steel enters the forming die from the runner, in order to prevent the surface of the molten steel from reacting with air, carbon powder is manually covered on the surface of the molten steel of the forming die and floats on the surface of the molten steel to achieve the effect of isolating the air as far as possible, and certainly, the carbon powder slowly reacts with the molten steel to gradually reduce the carbon powder, so that the carbon powder is periodically added. It should be noted that the reaction of the carbon powder and the molten steel does not affect the casting performance, which is actually detected.

The above mentioned is only the embodiment of the present invention, and not the limitation of the patent scope of the present invention, all the equivalent transformations made by the contents of the specification and the drawings, or the direct or indirect application in the related technical field, are included in the patent protection scope of the present invention.
