Description

Technical Field

[0001] This utility model relates to the field of casting technology, specifically to a spherical riser sleeve connection device. Background Technology

[0002] A riser is an additional portion attached to the top or side of a casting to prevent defects. Functionally, in a mold, the riser cavity is a cavity that stores molten metal. It supplies metal during casting formation, preventing shrinkage cavities and porosity, venting air, and collecting slag. The primary function of a riser is feeding. Different risers have different forms, sizes, and locations.

[0003] Spherical risers are suitable for horizontal molding. Compared to vertical molding lines, horizontal molding lines have the following advantages: lowering the core and chiller is easier in horizontal molding; in horizontal molding, the sprue is perpendicular to the parting surface, resulting in high effective utilization of the mold plate area, while the gating system of vertical lines is located on the parting surface, leading to low utilization of the mold plate area. However, because it is a spherical riser, the riser sleeve is made of two halves that fit together to enclose the riser. This is typically fixed with bolts, which is cumbersome and inconvenient for both fixing and disassembly. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a spherical riser sleeve connection device to solve the problem of cumbersome riser sleeve connection.

[0005] A spherical riser sleeve connection device includes a riser and a riser sleeve, wherein the riser sleeve is sleeved on the outside of the riser;

[0006] The riser sleeve includes a first template and a second template. A mold closing device is connected between the first template and the second template. The mold closing device includes a rotating ring, an insertion block, a locking block, a spring, and a sliding rod. The rotating ring is rotatably connected to the second template and has a notch. The insertion block is fixedly connected to the side of the rotating ring. A first groove is formed on the side of the first template, and the insertion block can be inserted into the first groove. A second groove is formed on the side of the insertion block. One end of the locking block is located in the second groove and is slidably connected to the second groove. The spring is located between the second groove and the locking block. The sliding rod is sleeved on the outside of the spring and passes through the locking block and is slidably connected to the locking block. A third groove is formed on the inner side of the first groove, and the locking block can be locked into the third groove.

[0007] Furthermore, it also includes: the length of the first groove is greater than the length of the insertion block, and the insertion block can slide within the first groove.

[0008] Furthermore, it also includes: one end of the card block is arc-shaped, and one side of the third groove is arc-shaped.

[0009] Furthermore, the end of the card block near the first groove is arc-shaped.

[0010] Furthermore, the spring is normally in a supporting position.

[0011] The beneficial effects of this utility model are as follows:

[0012] As can be seen from the above technical solution, the spherical riser sleeve connecting device provided by this utility model can quickly close the riser sleeve together through the mold closing device, and can prevent the riser sleeve from falling off during use; by rotating the rotating ring, the locking block is made to abut against the side of the third groove, so that the locking block is retracted into the second groove, thereby so that the locking block is no longer locked with the third groove, and the riser sleeve can be quickly disassembled.

[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0026] like Figure 1-9 As shown in the figure, the spherical riser sleeve connection device provided in this embodiment includes: a riser 2 and a riser sleeve 1, wherein the riser sleeve 1 is sleeved on the outside of the riser 2; the riser 2 can be connected to the outside of the casting.

[0027] The riser sleeve 1 includes a first template 112 and a second template 111. A mold closing device 3 for enclosing the riser sleeve 1 is connected between the first template 112 and the second template 111. The mold closing device 3 includes a rotating ring 31, an insertion block 32, a locking block 33, a spring 34, and a sliding rod 35.

[0028] The rotating ring 31 is rotatably connected to the second template 111, and the rotating ring 31 has a notch along its length, allowing it to rotate outside the second template 111. The insertion block 32 is fixedly connected to the side of the rotating ring 31, and the rotating ring 31 can drive the insertion block 32 to rotate. The first template 112 has a first groove 4 on its side, and the insertion block 32 can be inserted into the first groove 4. The length of the first groove 4 is greater than the length of the insertion block 32, allowing the insertion block 32 to slide within the first groove 4. This allows the locking block 33 located within the insertion block 32 to move, causing the locking block 33 to abut against the side of the third groove 7. Under force, the locking block 33 can retract into the second groove 5.

[0029] The insertion block 32 has a second groove 5 on its side. One end of the locking block 33 is located inside the second groove 5 and is slidably connected to it. The locking block 33 can retract into the second groove 5. The spring 34 is located between the second groove 5 and the locking block 33. In its normal state, the spring 34 is in a supporting position, allowing one end of the locking block 33 to extend out of the second groove 5. The sliding rod 35 is sleeved on the outside of the spring 34, limiting the spring 34 and preventing it from twisting. The sliding rod 35 passes through the locking block 33 and is slidably connected to it, so that the locking block 33 can only slide along the outside of the sliding rod 35. A third groove 7 is provided inside the first groove 4. The locking block 33 can be inserted into the third groove 7, so that the rotating ring 31 and the second template 111 will not separate from the first template 112. One end of the locking block 33 is arc-shaped, and one side of the third groove 7 is arc-shaped, so that the arc end of the locking block 33 can abut against the arc end of the third groove 7. The end of the locking block 33 near the first groove 4 is arc-shaped, so that when the locking block 33 contacts the first groove 4, the locking block 33 can be stretched into the second groove 5 under force.

[0030] The method of using this utility model is as follows: When it is necessary to place the riser sleeve 1 on the outside of the riser 2, align the first template 112 and the second template 111, and then snap the first template 112 and the second template 111 together. The insertion block 32 extends into the first groove 4, at which point the arc end of the locking block 33 abuts against the side of the first groove 4, and the locking block 33 retracts into the second groove 5 under force. When the insertion block 32 continues to be inserted, the locking block 33 moves to the third groove 7, the spring 34 is no longer compressed, and the spring 34 drives the locking block 33 to pop out. At this time, the locking block 33 is locked into the third groove 7, so that the first template 112 and the second template 111 are locked together and no longer separated. When it is necessary to separate the riser sleeve 1, rotate the rotating ring 31 to make the locking block 33 abut against the side of the third groove 7, so that the locking block 33 retracts into the second groove 5, so that the locking block 33 is no longer locked with the third groove 7, and the riser sleeve 1 can be quickly disassembled.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
