Example Embodiment

[0050] Example one:

[0051] Such as figure 1 with image 3 As shown, the pouring riser 2 of the present invention forms a bend from the opening position down to the passage that enters the pouring riser branching area 5, so that the connecting part of the pouring riser 2 and the pouring riser branching area 5 is Inclined pathway.

[0052] The above structure ensures that after the vent 9 of the pouring riser splitter area is set, it will not interfere with the pouring riser 2. The pouring riser 2 gives way to the pouring riser splitter vent 9 and can slow down the flow of liquid. The impact force of the lower part of the pouring riser 2.

Example Embodiment

[0053] Embodiment two:

[0054] The casting ball and casting section mold of the present invention is provided with a riser split runner 11, a main runner splitter area 10, a main runner 3 and a split runner 4. The casting ball, the casting section model and the split runner The runner 4 is connected, and the sprue sprue 11 connects the sprue sprue area 5 and the main sprue 3, and the main sprue sprue area 10 is provided in the main sprue 3 and split pouring. Lane 4 connection position.

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

[0056] The main runner 3 allows the liquid metal to flow down and inject quickly, and the split runner 4 separates the liquid metal from the main runner 3 into the molding cavity of the casting ball and casting section model. The liquid metal is instantly contained under the acceleration of gr...

Example Embodiment

[0059] Embodiment three:

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

[0061] The main runner 3 is set vertically downward, the split runner 4 is inclined downward from the middle to the two sides on both sides, and the casting ball and casting section models are connected to the split runner 4 vertically upwards. The overall arrangement is vertically downward and relatively obliquely arranged. 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%, and the product process yield rate is relatively high. . A feeding riser 6 is set above the main runner 3 to fully ensure the smooth flow and smooth exhaust of the liquid metal in the casting cavity, and it can achieve sufficient feeding 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...
