Problems solved by technology

[0014] The several patented technologies mentioned above have not fundamentally solved the problems that the pouring riser will cause blockage similar to the bottle mouth, the difficulty of molding small batches in the same cavity at one time, and the metal molds cannot be interchanged at will.
They all use two points or one point on the top for direct feeding, and the feeding is not sufficient and perfect

Embodiment 1

[0051] Such as figure 1 and image 3 As shown, the sprue riser 2 according to the present invention goes down from the opening position to the passage into the sprue riser diversion area 5, forming a bend, so that the part connecting the sprue riser 2 and the sprue riser diversion area 5 is Inclined pathway.

[0052] The above-mentioned structure ensures that after the vent hole 9 in the diversion area of ​​the pouring riser is set, it will not interfere with the vent hole 2 in the diversion area of ​​the pouring riser, and the vent hole 9 in the diversion area of ​​the pouring riser 2 will give way to the position of the vent hole 9 in the diversion area of ​​the pouring riser, and can slow down the impact of the liquid flow. The impact of the lower part of the pouring riser 2.

Embodiment 2

[0054] Casting balls and casting section molds according to the present invention are provided with a riser sub-runner 11, a main runner splitting area 10, a main runner 3 and a split runner 4. Channel 4 communicates, and the described sprue runner 11 communicates the sprue diversion area 5 with the main runner 3, and the main runner diversion area 10 is arranged between the main runner 3 and the split sprue Road 4 connection location.

[0055] Such as figure 1 and image 3 As shown, the runner is designed as the main runner 3 and the split runner 4, and the flow of liquid metal is accelerated by using the principle of the center of gravity downward.

[0056] The main runner 3 allows the liquid metal to flow and inject quickly downwards, and the split runner 4 divides the liquid metal in the main runner 3 into the molding cavity of the casting ball and the casting segment model, and the liquid metal is instantly absorbed by the acceleration of gravity. In the cavity, during...

Embodiment 3

[0060] Such as Figure 1 to Figure 4 As shown, the main runner 3 of the present invention is vertically arranged, and its number is more than one; at the upper end of the main runner 3, a feeding riser 6 is provided.

[0061] The main sprue 3 is set vertically downward, the two sides of the split sprue 4 are placed obliquely downward from the middle to both sides, and the casting ball and the casting segment model are vertically connected to the split sprue 4 in series. The overall arrangement is vertically downward and relatively inclined. Compared with the existing vertical parting mold, the free area is small, the sand mold space is fully utilized, the space utilization rate is increased by about 8 percentage points, and the product process yield rate is relatively high. . The feed riser 6 is set above the main runner 3, which fully ensures the smooth flow and smooth exhaust of the liquid metal in the casting cavity, and can realize sufficient shrinkage during condensation...

Abstract

The invention discloses a vertical-parting casting ball and casting section die. A plurality of casting balls and casting section models and air vents (7) are arranged on a parting surface of a die body (1), shape of the casting balls and casting section models is a spherical casting section model (8), or the shape of the casting balls and casting section models is a cylindrical casting section model (21), a dead head (2) and an air vent (7) are equipped on the upper part of the parting surface, a dead head splitting area (5) which is communicated with the dead head (2) is arranged in the lower opening of the dead head (2), and a dead head splitting area air vent (9) is arranged on the upper part of the dead head splitting area (5) to cause the dead head splitting area (5) to be communicated with the outer of the die. By the technical proposal, bottle-neck blockage of the dead head during casting can be overcome, overflow of liquid metal can be avoided or reduced, smooth flow of the liquid metal in the casting cavity can be fully ensured, and the casting ball product quality can be ensured.

Description

technical field [0001] The invention belongs to the technical field of thermal processing of metal materials, and relates to technological equipment for casting and forming wear-resistant material media. More specifically, the invention relates to a vertical split mold for casting balls and casting sections. Background technique [0002] At present, the demand for grinding media used in powder engineering, such as casting balls and casting segments, is increasing, and the product quality requirements are also getting higher and higher. With the popularization of the Disha line in the production of wear-resistant casting balls and casting segments, it is required to further improve product quality, increase production capacity and efficiency, simplify the operation of the production process, and continuously reduce production costs in the production of casting balls and casting segments. Among them, it has great potential and development prospects in the improvement and innov...
