[0026] As Figs. 1-2 The mold thread core cooling jacket clamping tool 100 of the utility model is used to clamp the mold thread core cooling jacket 200 for convenient processing.

[0027] The mold thread core cooling jacket 200 is divided into two sections, namely a front section 201 and a rear section 202, and both are cylindrical bodies, wherein the front section 201 has a larger diameter.

[0028] The mold thread core cooling jacket clamping tool 100 comprises a tool body 1, an arc pressing block 2, a pull pin 3 and a jack 4.

[0029] The tool body 1 is provided with a clamping groove 11, a pressing block groove 12 communicated with the clamping groove 11, a jack hole 14 and a pull pin hole 13 communicated with the pressing block groove 12 in the radial direction.

[0030] The tool body 1 is provided with a first part 15 and a second part 16 along the axial direction, and the insertion end is arranged on the first part 15. The first part 15 and the second part 16 are both cylindrical and coaxially arranged, and the diameter of the second part 16 is larger than that of the first part 15. The second part 16 is arranged to have a larger diameter, which can facilitate clamping by a machine tool and facilitate the user to distinguish the front and back.

[0031] In this embodiment, the jackscrew 4 is arranged on the first part 15, and the pull pin 3 is arranged on the second part 16. Specifically, the jackscrew hole 14 is arranged on the first part 15, and the pull pin hole 13 is arranged on the second part 16.

[0032] The insertion end is provided with a guide portion. The guide portion facilitates the insertion of the mold threaded core cooling sleeve 200, especially the rear section 202 of the mold threaded core cooling sleeve 200.

[0033] The clamping groove 11 is used for the insertion of the mold threaded core cooling sleeve 200. The diameter of the clamping groove 11 is slightly larger than the diameter of the rear section 202 of the mold threaded core cooling sleeve 200 and smaller than the diameter of the front section 201. The front section 201 is inserted into the clamping groove 11, and the rear section 202 remains outside the tool body 1, which can play a limiting role.

[0034] The arc-shaped pressing block 2 is arranged in the pressing block groove 12. In this embodiment, the cross section of the pressing block groove 12 is a rectangle with one side open. The pressing block groove 12 extends along the axial direction and penetrates the tool body 1 along the axial direction.

[0035] The arc-shaped pressing block 2 is provided with an arc surface 21 on the side facing the clamping groove 11, and a connecting screw hole 22 on the side away from the clamping groove 11. The arc surface 21 is used to abut against the mold threaded core cooling sleeve 200.

[0036] The mold threaded core cooling sleeve 200 is provided with grooves 203 spaced apart in the circumferential direction. The curvature of the arc surface 21 is greater than that of the groove 203, so as to avoid the arc-shaped pressing block 2 from being stuck in the groove 203. The grooves 203 can be uniformly arranged or non-uniformly arranged, which is not limited in this embodiment.

[0037] The puller 3 is screwed with the connecting screw hole 22 through the puller hole 13, so as to drive the arc block 2 to move away from the clamping groove 11. In the embodiment, the top screw hole 14 is a threaded hole. Through the rotation of the puller 3, the arc block 2 can be driven to move away from the clamping groove 11, so as to reserve enough space in the clamping groove 11 for the mold screw core cooling jacket 200 to enter.

[0038] The top screw 4 is in abutment with the arc block 2 through the top screw hole 14, so as to drive the arc block 2 to move towards the clamping groove 11. After the mold screw core cooling jacket 200 is accommodated in the clamping groove 11, the top screw 4 can drive the arc block 2 to move towards the clamping groove 11, so that the arc block 2 abuts against the mold screw core cooling jacket 200, avoiding the axial and radial movement of the mold screw core cooling jacket 200.

[0039] The number of the top screw 4 is two, and the number of the puller 3 is one. The two top screws 4 and the puller 3 are arranged along the axial direction of the tool body 1. In the embodiment, the two top screws 4 and the puller 3 are located on the same straight line.

[0040] Further, the two top screws 4 are arranged on the side close to the insertion end, and the puller 3 is arranged on the side away from the insertion end.

[0041] The arc surface 21 of the arc block 2 is provided with a step to divide the arc surface 21 into a first surface 23 and a second surface 24. The first surface 23 and the second surface 24 are connected along the axial direction, and the first surface 23 protrudes towards the clamping groove 11 relative to the second surface 24. That is, in the embodiment, when the side of the arc block 2 away from the clamping groove 11 abuts against the tool body 1, the first surface 23 is closer to the clamping groove 11, and when the mold screw core cooling jacket 200 is inserted into the clamping groove 11, the second surface 24 is away from the mold screw core cooling jacket 200, leaving a clearance between the second surface 24 and the mold screw core cooling jacket 200. The first surface 23 and the second surface 24 correspond to the first part 15 and the second part 16 of the tool body 1 along the radial direction, respectively. Therefore, when the puller 3 is arranged on the second part 16, because there is a clearance, pulling the arc block 2 from one side will not cause an imbalance problem.

[0042] Further, when the mold screw core cooling jacket 200 is inserted into the clamping groove 11, the diameter of the clamping groove 11 is 0.002 mm larger than that of the mold screw core cooling jacket 200, and the distance between the first surface 23 and the mold screw core cooling jacket 200 is at least 0.05 mm, facilitating clamping of the mold screw core cooling jacket 200.

[0043] The mold thread core cooling sleeve clamping tool 100 of the utility model processes using method as follows:

[0044] The tool body 1 is processed on the grinding machine once, including the outer surface, the inner hole and the end surface of the two ends, guaranteeing the concentricity, roundness and perpendicularity; the pull nail 3 is used to pull the arc pressing block 2, guaranteeing that there is enough gap between the arc pressing block 2 and the clamping groove 11 for the mold thread core cooling sleeve 200 to be inserted; when the mold thread core cooling sleeve 200 is inserted and reaches the processing position along the axial direction, the top pin 4 can be screwed to press the mold thread core cooling sleeve 200, and after correction, the mold thread core cooling sleeve 200 can be processed; and after processing is completed, the top pin 4 can be unscrewed in the reverse direction to remove the mold thread core cooling sleeve 200, and the next mold thread core cooling sleeve 200 only needs to be clamped for processing, without the need for secondary correction.

[0045] The mold thread core cooling sleeve clamping tool 100 of the utility model does not need to be corrected for subsequent processing after completing the first clamping correction, achieving the effect of quick and stable clamping; the clamping of the mold thread core cooling sleeve 200 is completed through the pull nail 3 and the top pin 4, and the mold thread core cooling sleeve 200 is not easy to be damaged.

[0046] The technical features of the above-described embodiments can be combined in any manner, and to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0047] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but it should not be understood as the limitation of the scope of the utility model patent. It should be pointed out that for ordinary skilled persons in the art, on the premise of not departing from the concept of the utility model, a number of modifications and improvements can be made, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
