Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of casting, in particular to a casting mould for a vertical line shell which changes double risers into a single riser. Background Art
[0002] Casting is a method of pouring liquid metal into a casting cavity that adapts to the shape of the part, and then cooling and solidifying it to obtain a part or blank. The cast material is mostly metal that was originally solid but heated to liquid state (for example: copper, iron, aluminum, tin, lead, etc.), and the mold material can be sand, metal or even ceramic. The methods used will vary depending on different requirements. The runner is the channel for transporting molten metal from the ladle to the mold, and the riser is a cavity reserved in the casting to accommodate defects such as gas, inclusions and shrinkage cavities generated during the solidification process.
[0003] In traditional casting molds, it is generally necessary to set a riser on each side of a single casting. However, after the casting is completed, it is necessary to dismantle the riser and the casting and grind the riser neck. There is a problem that two risers are required for the production of a single casting, resulting in low process yield and low production efficiency. Therefore, it does not meet the existing needs, and a vertical line shell double-riser single-riser casting mold is proposed. Utility Model Content
[0004] The purpose of the utility model is to provide a casting mold for a vertical line shell that changes the double risers into a single riser. By providing a riser on each side of a single casting instead of providing a riser in the middle of the two castings, the production efficiency and process yield are improved. At the same time, the water entry angle of the riser neck is adjusted and the front neck and the supplementary portion of the riser neck are increased, thereby reducing the shrinkage inside the casting and solving the problems in the prior art.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-riser-to-single-riser casting mold for a vertical line shell, comprising a first runner and a second runner, and also comprising a first riser and a second riser, and at least two first risers and second risers are provided. The first riser is located below the first runner, and first castings are provided on both sides of the first riser. A first riser neck is provided on the lower side of the first riser, and a first breaking position is provided on the upper side of the first riser. The second riser is located on one side of the second runner, and second castings are provided on both sides of the second riser. A second riser neck is provided on the lower side of the second riser, and a second breaking position is provided on the upper side of the second riser.
[0006] Preferably, the first riser is connected to the first casting via a first riser neck, the second riser is connected to the second casting via a second riser neck, and the diameter of the first casting is smaller than that of the second casting.
[0007] Preferably, the first runner includes a first main runner, a first drainage runner, a first filter residue sheet, a first auxiliary runner and a first pouring cup, and the first risers are connected to each other through the first drainage runner.
[0008] Preferably, the second runner includes a second main horizontal runner, a second drainage runner, a second filter residue sheet, a second auxiliary horizontal runner, a main vertical runner, an inner runner and a second pouring cup, and the second riser is connected to the second riser through the second drainage runner.
[0009] Preferably, the first main runner is located below the first auxiliary runner, the first main runner is connected to the first pouring cup, at least two first filter residue sheets are provided, and both first filter residue sheets are connected to the first auxiliary runner.
[0010] Preferably, the second main horizontal runner is located above the second auxiliary horizontal runner, the second main horizontal runner is connected to the second pouring cup mouth, the second auxiliary horizontal runner is connected to the second filter residue sheet, and there are at least two main vertical runners, which are respectively located on both sides of the second auxiliary horizontal runner, one end of the ingrown runner is connected to the main vertical runner, and the other end of the ingrown runner is connected to the second casting.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] 1. The utility model provides a riser in the middle of the two first castings, so that only two risers are needed to produce four first castings, that is, a single riser solution. Compared with the traditional method of providing a riser on each side of a single first casting, which requires six risers to produce four first castings, that is, a double riser solution, the production efficiency and process yield are improved. At the same time, due to the limitation of mold size, the traditional double riser solution can only place two second casting cavities inside the mold when producing a second casting with a larger diameter, while the single riser solution can place four second casting cavities inside the same mold, which directly doubles the production efficiency.
[0013] 2. The utility model reduces the shrinkage inside the casting by adjusting the water entry angle of the riser neck and increasing the front neck and the supplementary portion of the riser neck. At the same time, after the casting is produced, each riser needs to be broken apart from the casting and the riser neck polished. The traditional double-riser solution requires grinding the riser neck twice for each casting and using hydraulic pliers to break it apart twice, while the single-riser solution of the utility model only requires grinding the riser neck once for each casting and using hydraulic pliers to break it apart once, thereby improving production efficiency.

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] In order to solve the problem that two risers are required for the production of a single casting, resulting in low process yield and low production efficiency, please refer to Figure 1-4 The utility model provides an embodiment: a double-riser-to-single-riser casting mold for a vertical line shell, comprising a first runner 1 and a second runner 4, and also comprising a first riser 2 and a second riser 5. There are at least two first risers 2 and second risers 5. The first riser 2 is located below the first runner 1, and first castings 3 are provided on both sides of the first riser 2. A first riser neck 201 is provided on the lower side of the first riser 2, and a first breaking position 202 is provided on the upper side of the first riser 2. The second riser 5 is located on one side of the second runner 4, and second castings 6 are provided on both sides of the second riser 5. A second riser neck 501 is provided on the lower side of the second riser 5, and a second breaking position 502 is provided on the upper side of the second riser 5.
[0021] The first riser 2 is connected to the first casting 3 via a first riser neck 201 , and the second riser 5 is connected to the second casting 6 via a second riser neck 501 . The diameter of the first casting 3 is smaller than that of the second casting 6 .
[0022] The first runner 1 includes a first main runner 101, a first drainage runner 102, a first filter residue sheet 103, a first auxiliary runner 104 and a first pouring cup 105. The first riser 2 is connected to the first riser 2 through the first drainage runner 102. The first main runner 101 is located below the first auxiliary runner 104. The first main runner 101 is connected to the first pouring cup 105. At least two first filter residue sheets 103 are provided, and both first filter residue sheets 103 are connected to the first auxiliary runner 104.
[0023] A first riser 2 is set in the middle of the two first castings 3, so that only two first risers 2 are needed to produce four first castings 3, that is, a single first riser 2 solution. Compared with the traditional method of setting a first riser 2 on each side of a single first casting 3, so that six first risers 2 are needed to produce four first castings 3, that is, a double first riser 2 solution, the production efficiency is improved and the process yield is further improved.
[0024] The second runner 4 includes a second main horizontal runner 401, a second drainage runner 402, a second filter residue sheet 403, a second auxiliary horizontal runner 404, a main vertical runner 405, an ingrown runner 406 and a second pouring cup 407. The second riser 5 is connected to the second riser 5 through the second drainage runner 402. The second main horizontal runner 401 is located above the second auxiliary horizontal runner 404. The second main horizontal runner 401 is connected to the second pouring cup 407. The second auxiliary horizontal runner 404 is connected to the second filter residue sheet 403. There are at least two main vertical runners 405, and the two main vertical runners 405 are respectively located on both sides of the second auxiliary horizontal runner 404. One end of the ingrown runner 406 is connected to the main vertical runner 405, and the other end of the ingrown runner 406 is connected to the second casting 6.
[0025] Due to the limitation of mold size, the traditional method of producing the second casting 6 requires setting a second riser 5 on both sides of the second casting 6, so that only two cavities of the second casting 6 can be placed inside the mold during production. However, the present invention uses a new solution, that is, setting a second riser 5 between the two second castings 6, so that four cavities of the second casting 6 can be placed inside the same mold, which directly doubles the production efficiency and further improves the process output rate.
[0026] The utility model adjusts the water entry angle of the first riser neck 201 and the second riser neck 501 and increases the front neck and the subsidy of the first riser neck 201 and the second riser neck 501, thereby reducing the shrinkage inside the casting; at the same time, after the casting is produced, each first riser 2 or the second riser 5 needs to be broken between the riser and the casting and the riser neck is polished. The traditional double-riser solution requires grinding the riser neck twice for each casting and using hydraulic pliers to break it twice, while the single-riser solution of the utility model only requires grinding the riser neck once for each casting and using hydraulic pliers to break it once, thereby further improving production efficiency.
[0027] Working principle: Instead of setting a first riser 2 or a second riser 5 on both sides of a single first casting 3 or a second casting 6, a first riser 2 or a second riser 5 is set in the middle of two first castings 3 or second castings 6, thereby improving production efficiency and process yield. At the same time, the water entry angle of the first riser neck 201 or the second riser neck 501 is adjusted and the front neck and the subsidy of the first riser neck 201 or the second riser neck 501 are increased, thereby reducing the internal shrinkage of the first casting 3 or the second casting 6.
