Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold positioning equipment technology, specifically to a casting mold positioning device. Background Technology
[0002] Abrasives are tools used for grinding, polishing, and grinding. Most abrasives are man-made abrasives made of abrasives and binders, while there are also natural abrasives made directly from natural minerals. In addition to being widely used in machinery manufacturing and other metal processing industries, abrasives are also used in grain processing, papermaking, and the processing of non-metallic materials such as ceramics, glass, stone, plastics, rubber, and wood.
[0003] The prior art patent publication number CN220145654U describes a positioning device for mechanical casting abrasives. This patent includes a mold body, a positioning mechanism, a limiting component, a fixed cylinder, a moving groove, a clamping block, a positioning groove, a positioning plate, bolts, and a threaded groove. In use, the mold body is inserted into the fixed cylinder. The clamping block moves according to the diameter of the mold body. When the clamping block is in contact with the outer wall of the mold body, the positioning plate is inserted into the positioning groove. Then, the bolts are screwed into the threaded groove, and the mold body is clamped by the clamping block. When the fixed cylinder rotates, it does not affect the stability of the mold body. The limiting component prevents the clamping block from dislodging from the moving groove and prevents the clamping block from being lost.
[0004] Although the aforementioned patent achieves a fixed connection between the mold body and the motor output shaft when the clamping block contacts the motor output end, the surface of the clamping block will inevitably suffer severe wear after long-term use. Once worn, it will reduce the firmness to the mold body. However, the clamping block and the lead screw are directly connected by rotation, and the internal space of the connecting groove is limited, making it very inconvenient to manually replace the clamping block. Utility Model Content
[0005] To solve the above-mentioned technical problems, a casting mold positioning device is provided. This device addresses the issue that in the prior art, the surface of the clamping block inevitably suffers severe wear after long-term use, which reduces its stability to the mold body. Furthermore, the clamping block and the lead screw are directly connected by a rotary joint, and the internal space of the connecting groove is limited, making it very inconvenient to manually replace the clamping block.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a casting mold positioning device, comprising a fixed cylinder, a connecting groove disposed at the bottom end of the fixed cylinder, and a plurality of replaceable clamping parts disposed around the connecting groove;
[0007] The replaceable clamping part includes a clamping block that slides in the connecting groove and a screw threaded through the inner wall of the fixed cylinder, and an assembly assembly is provided between the screw and the clamping block.
[0008] Preferably, the assembly includes a connecting post rotatable at the end of the lead screw facing the clamping block, a positioning block vertically fixed on the side of the clamping block facing the lead screw, a notch adapted to the positioning block at the end of the connecting post, a buffer groove transversely arranged in the inner wall of the connecting post communicating with the notch, an elastic clip for locking the positioning block in the notch in the buffer groove, and a push-pull member cooperating with the elastic clip at the end of the lead screw away from the clamping block.
[0009] Preferably, the elastic locking element includes a C-shaped sliding base that slides in the buffer groove and a locking block that slides in an opening on one side of the sliding base. One end of the locking block is fixed with a compression spring between it and the innermost inner wall of the sliding base. The positioning block has a positioning socket, and the other end of the locking block is sloping and passes through the positioning socket.
[0010] Preferably, the push-pull component includes a control screw disposed on the side of the lead screw away from the connecting post, one end of the control screw being threaded through the lead screw and extending into the buffer groove to be rotatably connected to the slide block, and the other end of the control screw being fixed with a rotating block.
[0011] Preferably, the top of the clamping block is provided with a wedge-shaped groove, a connecting block is inserted into the wedge-shaped groove, and a telescopic rod is fixed between the connecting block and the inner wall of the connecting groove.
[0012] Compared with the prior art, the advantages of this utility model are: through the setting of the assembly components, the elastic clips and push-pull parts make the connection between the connecting column and the clamping block detachable, which makes it easy to quickly replace the clamping block when it wears out after long-term use, thus improving its practicality.

[0018] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0019] Reference Figure 1-3 As shown, a casting mold positioning device includes a fixed cylinder 1, a connecting groove disposed at the bottom end of the fixed cylinder 1, and a plurality of replaceable clamping parts disposed around the connecting groove.
[0020] The replaceable clamping part includes a clamping block 2 that slides in the connecting groove and a screw 3 that is threaded through the inner wall of the fixed cylinder 1. An assembly component is provided between the screw 3 and the clamping block 2.
[0021] After the motor output shaft is inserted into the connecting groove, the screw rod 3 is turned, and the screw rod 3 extends into the connecting groove under the thread structure. The push-pull clamp 2 slides in the connecting groove until it contacts the motor output shaft. In this way, the several interchangeable clamping parts cooperate with each other to achieve the effect of fixing the fixed cylinder 1 on the motor output shaft.
[0022] Furthermore, referring to Figure 2 As shown, it is worth noting that the assembly includes a connecting post 4 that rotates on the end of the lead screw 3 facing the clamping block 2. A positioning block 5 is vertically fixed on the side of the clamping block 2 facing the lead screw 3. A notch adapted to the positioning block 5 is opened at the end of the connecting post 4. A buffer groove connected to the notch is arranged horizontally in the inner wall of the connecting post 4. An elastic clip for locking the positioning block 5 in the notch is provided in the buffer groove. A push-pull member that cooperates with the elastic clip is provided at the end of the lead screw 3 away from the clamping block 2.
[0023] By assembling the components, the elastic clips and push-pull parts allow for a detachable connection between the connecting column 4 and the clamping block 2, making it easy to quickly replace the clamping block 2 when it wears out after long-term use, thus improving its practicality.
[0024] Furthermore, referring to Figure 3 As shown, it is worth noting that the elastic clip includes a C-shaped sliding base 6 that slides in the buffer groove and a locking block 7 that slides in an opening on one side of the sliding base 6. A compression spring 8 is fixed between one end of the locking block 7 and the innermost inner wall of the sliding base 6. A positioning socket is provided on the positioning block 5. The other end of the locking block 7 is sloping and passes into the positioning socket.
[0025] The push-pull component includes a control screw 10 located on the side of the lead screw 3 away from the connecting column 4. One end of the control screw 10 is threaded through the lead screw 3 and extends into the buffer groove to be rotatably connected to the slide block 6. The other end of the control screw 10 is fixed with a rotating block 9.
[0026] When the clamping block 2 wears out after long-term use, simply turn the knob to rotate the block 9 so that the control screw 10 extends outward from the inside of the lead screw 3 under the thread structure, thereby pulling the slide block 6 and removing the locking block 7 from the positioning socket on the positioning block 5, that is, releasing the fixation of the positioning block 5 so that the clamping block 2 can automatically exit from the connecting groove under gravity, thus realizing the disassembly of the clamping block 2.
[0027] When installing clamping block 2, simply insert clamping block 2 into the connecting groove, causing positioning block 5 to enter the notch and abut against the inclined surface of locking block 7. In this way, locking block 7 is squeezed and contracted to supply the inner side of slide 6 and compresses the compression spring 8. When positioning block 5 is fully inserted into the notch, locking block 7 can automatically insert into the positioning socket under the elastic force of compression spring 8, thus achieving self-fixation of clamping block 2.
[0028] Furthermore, referring to Figure 3 As shown, it is worth noting that the top of the clamping block 2 is provided with a wedge-shaped groove, and a connecting block 12 is inserted into the wedge-shaped groove. A telescopic rod 11 is fixed between the connecting block 12 and the inner wall of the connecting groove.
[0029] When the clamping block 2 is inserted into the connecting groove, the connecting block 12 can enter the wedge-shaped groove at the top of the clamping block 2, so that the telescopic rod 11 is connected to the clamping block 2 as one unit. Then, when the screw 3 is turned to push and pull the clamping block 2 through the connecting groove, the telescopic rod 11 can move the clamping block 2 in parallel, thus guiding the clamping block 2.
[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
