Furthermore, a pouring section is arranged on the parallel surface, and the diameter of the pouring section is gradually increased from top to bottom and is in a circular truncated cone shape.

Further, the width of the exhaust section gradually increases from the direction close to the casting main body to the direction far away from the casting main body.

Further, the thickness of the exhaust section is gradually reduced from the center to two sides.

Furthermore, the slag collecting block is connected with the side edge and integrally formed.

Compared with the prior art, the beneficial effects of the utility model reside in that:

1. the design position of the pouring gate avoids the weak part of the product, and the reserved part can be used as shrinkage supplement and backfill for the casting main body in the casting cooling process;

meanwhile, the designed position of the pouring gate is a plane, so that later-stage processing and cutting are facilitated.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 2, the round magnesium alloy casting with high yield comprises a casting main body 1, and a plurality of slag collecting blocks 2 and exhaust sections 3 which are located around the casting main body 1, wherein the casting main body 1 is of a hollow thin-wall structure, a projection plane in the vertical direction is round, holes or grooves with different sizes and structures are formed in the surface of the casting main body 1, and the casting main body comprises a convex parallel plane 6, and the parallel plane 6 is located at the highest point of the casting main body 1.

Casting main part 1 is including the ring form, and with self integrated into one piece's side 4, and this embodiment with each exhaust section 3 evenly distributed around side 4 and with side 4 integrated into one piece, each collect 2 homogeneous one of cinder block and correspond the bottom of locating exhaust section 3 and with the exhaust section 3 integrated into one piece that corresponds. Because a part of the side edge 4 has a convex structure, the exhaust section 3 and the slag collecting block 2 are not arranged at the part.

The bottoms of the grooves on the casting main body 1 are integrally formed with the surface of the casting main body 1 through the side walls, so that the metal quality on the casting main body 1 is improved in a phase-changing manner, and the structural strength is improved.

The pouring section 5 is designed on the parallel surface 6, the diameter of the pouring section 5 is gradually increased from top to bottom and is in a circular truncated cone shape, the diameter of the bottom of the pouring section 5 corresponds to the size of the parallel surface 6, and the impact of injected molten liquid on the cavity and other parts of the casting main body 1 is reduced by increasing the flow area under the condition that the pressure of the molten liquid is unchanged as far as possible.

The width of exhaust section 3 is from being close to casting main part 1 to keeping away from casting main part 1 direction crescent, under the prerequisite in assurance exhaust space, reduces exhaust section 3 and the horizontal connection area of side 4, makes things convenient for the later stage to exhaust section 3, collect the segmentation between sediment piece 2 and casting main part 1 and tailor and polish.

And the thickness of the exhaust section 3 is gradually reduced from the center to two sides, which means that the contact area between the side surface of the exhaust section 3 and the side wall of the exhaust groove at the upper end of the mold is small, and the friction and the resistance between the exhaust section 3 and the mold are reduced when the mold is removed, so that the mold removal of the casting main body 1 is more labor-saving.

In order to avoid the fracture or bending of the casting main body 1 and the exhaust section 3 in the demolding process, in the embodiment, the slag collecting block 2 and the exhaust section 3 are integrally formed and connected, and meanwhile, the slag collecting block 2 and the side edge 4 of the casting main body 1 are connected and integrally formed, so that the structural strength of the position is enhanced, and the casting main body 1 can be smoothly supported when the slag collecting block 2 is jacked up by a mold thimble.

The structural design in the embodiment combines the characteristics of magnesium alloy materials, a mold is matched, a thimble for demolding is not designed below the casting main body 1, demolding depends on the slag collecting block 2 and the exhaust section 3, the risk that the casting main body 1 is contacted with external force and surface abrasion occurs is reduced, the yield of self casting is improved, the exhaust section 3, the slag collecting block 2, the pouring section 5 and the like can be cut off at the later stage, all cutting points of the embodiment are planes, the processing is convenient, and the casting main body 1 is not damaged.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
