[0002] Currently, the impeller mold sprue sleeve is a mold component used in the manufacture of impeller parts. It is mainly responsible for guiding the molten material into the mold cavity and controlling the flow path and rate of the molten material.

[0003] Among them, after searching, the Chinese patent with the announcement number CN216096280U discloses a gate sleeve for an impeller mold. The above patent uses the structural scheme of a sealing cover to realize the function of protecting the top of the gate sleeve. However, since the rotation point between the gate sleeve and the sealing cover is located at the end of the gate sleeve, it will affect the insertion of the casting head into the gate sleeve, resulting in insufficient plug-in sealing between the casting head and the gate sleeve. Therefore, in order to advance the technology of the industry, better realize the protection function of the top of the gate sleeve, and improve the competitiveness of the core technology, this application proposes a new implementation plan that is different from the gate sleeve protection structure and usage method in the prior art. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the rotation point between the existing sprue sleeve and the sealing cover is located at the end of the sprue sleeve, which affects the insertion of the casting head into the sprue sleeve and causes insufficient sealing between the casting head and the sprue sleeve. A sprue sleeve for an impeller mold is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A sprue sleeve for an impeller mold comprises a sprue sleeve body, a mounting plate provided on the outer surface of the sprue sleeve body, and a rear base fixedly connected to the upper surface of the mounting plate, a protective assembly provided above the sprue sleeve body, the protective assembly comprising a top plate, the bottom of the top plate contacts the upper surface of the sprue sleeve body, and a protective cover fixedly connected to the bottom of the top plate, the two ends of the top plate are respectively fixedly connected to a connecting block and a handle, and the bottom end of the connecting block is rotatably connected to the top end of the rear base.

[0007] Furthermore, the protective cover is an annular structure, and the top end of the sprue sleeve body is located inside the protective cover.

[0008] Furthermore, the upper surface of the mounting plate is fixedly connected to the front base, and the top of the front base is in contact with the bottom of the handle.

[0009] Furthermore, the upper surface of the front base and the bottom of the handle are respectively embedded with magnet blocks, and the two magnet blocks are attracted to each other.

[0010] Furthermore, a rubber pad is fixedly connected to the upper surface of the mounting plate, and the position of the rubber pad corresponds to that of the protective component.

[0011] Furthermore, a plurality of mounting holes are provided on the upper surface of the mounting plate.

[0012] Furthermore, a connecting ring is fixedly connected to the upper surface of the mounting plate, the sprue sleeve body is located in the connecting ring, and the connecting ring and the sprue sleeve body are fixed by bolts.

[0013] The beneficial effects of the utility model are:

[0014] 1. The design of the rotatable connection between the connecting block on the protective component and the rear base on the mounting plate allows the height of the rear base and the connecting block to be lower than the sprue bushing body after the protective component is flipped open. This prevents the protective component from blocking the sprue bushing body when in use, ensuring a sealed connection between the sprue bushing body and the casting head.

[0015] 2. Through the design of the protective component, the top plate and protective cover in the protective component can protect the top and sides of the sprue bushing body respectively to prevent dust and impurities from entering the sprue bushing body, ensuring the cleanliness of the sprue bushing body when not in use.

[0016] 3. Through the design of the magnet blocks on the handle and the front base, the two magnet blocks can pre-fix the protective component to prevent the protective component from being easily opened, thereby ensuring the protective effect of the protective component on the gate sleeve body.

[0017] 4. Through the design of the connecting ring, since the connecting ring and the gate sleeve body are connected by bolts, and the bolt connection part is located on the outside of the connecting ring, it is convenient for the operator to screw the bolt connection part, thereby facilitating the disassembly and assembly between the gate sleeve body and the connecting ring.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1

[0026] Reference Figures 1-4 A sprue sleeve for an impeller mold includes a sprue sleeve body 1, a mounting plate 2 is provided on the outer surface of the sprue sleeve body 1, and a rear base 3 is welded to the upper surface of the mounting plate 2. A protective component 4 is provided above the sprue sleeve body 1, and the protective component 4 includes a top plate 401, the bottom of the top plate 401 contacts the upper surface of the sprue sleeve body 1, and a protective cover 402 is welded to the bottom of the top plate 401. The top plate 401 and the protective cover 402 can protect the top and side of the sprue sleeve body 1 respectively. To prevent dust and impurities from entering the sprue sleeve body 1, a connecting block 403 and a handle 404 are welded to both ends of the top plate 401, and the bottom end of the connecting block 403 is rotatably connected to the top end of the rear base 3. Through the design of the rotatable connection between the connecting block 403 and the rear base 3, after the protective component 4 is flipped open, the heights of the rear base 3 and the connecting block 403 are lower than the sprue sleeve body 1, thereby preventing the protective component 4 from blocking the sprue sleeve body 1 when in use and ensuring a sealed connection between the sprue sleeve body 1 and the casting head.

[0027] Among them, the protective cover 402 is an annular structure, and the top of the gate sleeve body 1 is located in the protective cover 402. The annular protective cover 402 can better protect the top outer side of the gate sleeve body 1, ensuring the protective performance of the protective component 4.

[0028] A front base 5 is welded to the upper surface of the mounting plate 2, and the top of the front base 5 is in contact with the bottom of the handle 404. The handle 404 is used for the operator to hold the protective component 4 when it is flipped over. The upper surface of the front base 5 and the bottom of the handle 404 are respectively embedded with magnet blocks 6, and the two magnet blocks 6 are adsorbed on each other. Through the design of the magnet blocks 6 on the handle 404 and the front base 5, the two magnet blocks 6 can pre-fix the protective component 4 to prevent the protective component 4 from being easily opened, thereby ensuring the protective effect of the protective component 4 on the gate sleeve body 1.

[0029] At the same time, a rubber pad 7 is bonded to the upper surface of the mounting plate 2, and the rubber pad 7 corresponds to the position of the protective component 4. The rubber pad 7 is used to support the protective component 4 after it is flipped over. A plurality of mounting holes 8 are opened on the upper surface of the mounting plate 2. The mounting holes 8 are used to connect and fix the mounting plate 2 and the upper mold of the impeller.

[0030] The working principle of this embodiment is as follows: when in use, the operator first installs the mounting plate 2 on the upper surface of the impeller upper mold. At this time, the sprue sleeve body 1 is sealed and plugged into the impeller upper mold, and the flow channel in the sprue sleeve body 1 is connected to the mold core cavity of the impeller mold; when it is necessary to produce the impeller, the operator first holds the handle 404 and flips the protective component 4 open until the top plate 401 is located on the rubber pad 7, and then inserts the casting head into the sprue sleeve body 1, and the molten material can be injected into the mold core cavity through the sprue sleeve body 1. In this way, The installation and use of the sprue sleeve are completed; during the non-impeller production period, the operator can cover the protective component 4 on the sprue sleeve body 1, and the two magnet blocks 6 can pre-fix the protective component 4 to prevent the protective component 4 from being easily opened, thereby ensuring the protective effect of the protective component 4 on the sprue sleeve body 1, and the top plate 401 and the protective cover 402 in the protective component 4 can respectively protect the top and sides of the sprue sleeve body 1 to prevent dust and impurities from entering the sprue sleeve body 1, thereby ensuring the cleanliness of the sprue sleeve body 1 when not in use.

[0032] Reference Figure 5 A connecting ring 9 is welded on the upper surface of the mounting plate 2, the sprue sleeve body 1 is located in the connecting ring 9, and the connecting ring 9 and the sprue sleeve body 1 are fixed by bolts. The connecting ring 9 is used to connect the mounting plate 2 and the sprue sleeve body 1, which facilitates the replacement of the sprue sleeve body 1.

[0033] The working principle of this embodiment is as follows: when in use, the connecting ring 9 and the sprue sleeve body 1 are connected by bolts, and the bolt connection part is located on the outside of the connecting ring 9, which is convenient for the operator to screw the bolt connection part, thereby facilitating the disassembly and assembly between the sprue sleeve body 1 and the connecting ring 9, and facilitating the replacement and maintenance of the sprue sleeve body 1.
