Embodiments of this application are shown in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this application more thorough and comprehensive.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the description of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

It should also be understood that the terms "include" or "comprise" or "have" etc. specify the presence of the stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0034] Referring to Figures 1-2 As shown in FIGS. and 7, the present utility model provides a technical solution: an internal chiller 10, and an anti-loosening groove 11 is formed on the internal chiller 10.

[0035] In this embodiment, during use, the internal chill 10 is placed in the reserved hole of the wear-resistant plate wax pattern, and high-temperature wax liquid is dropped into the reserved hole. The high-temperature wax liquid flows into the anti-loosening groove 11 along the gap between the internal chill 10 and the reserved hole. The anti-loosening groove 11 is filled with the high-temperature wax liquid. After the high-temperature wax liquid cools and solidifies, the internal chill 10 is fixed in the wear-resistant plate wax pattern, which can prevent the internal chill 10 from loosening.

[0036] Refer to the appendix Figures 1-2 As shown, in some embodiments, the cross-section of the internal chill 10 is a racetrack shape.

[0037] In this embodiment, such a shape can form an accommodation space approximately in the shape of a semi-circle between the plane of the internal chill 10 and the reserved hole, so that after the high-temperature wax liquid is dropped in, the accommodation space can hold more high-temperature wax liquid. After the high-temperature wax liquid solidifies in the accommodation space, it can form a wax block approximately in the shape of a semi-circle, which can play a role in preventing the internal chill 10 from rotating.

[0038] Refer to the appendix Figures 1-2 As shown in FIGS. 3 and 4, in some embodiments, it includes a connecting seat 20, and the connecting seat 20 is arranged on the internal chill 10.

[0039] In this embodiment, when the reserved hole is stepped, after the internal chill 10 is assembled and before the high-temperature wax liquid solidifies, by matching the connecting seat 20 with the larger space of the reserved hole, the internal chill 10 can be prevented from rotating.

[0040] Refer to the appendix Figures 1-5 As shown, in some embodiments, it includes a plurality of fasteners 30. A plurality of first connection holes 12 are formed at one end of the internal chill 10 close to the connecting seat 20. The connecting seat 20 is provided with second connection holes 21 corresponding to each internal chill 10. The fasteners 30 correspond to the first connection holes 12 and the second connection holes 21 one by one. When the connecting seat 20 and the internal chill 10 are assembled, the fasteners 30 are matched with the second connection holes 21 and the first connection holes 12, and the connecting seat 20 and the internal chill 10 can be fastened.

[0041] Exemplarily, both the first connection holes 12 and the second connection holes 21 can be threaded holes, and the fasteners 30 can be bolts or screws, etc.

[0042] In this embodiment, by matching the fasteners 30 with the second connection holes 21 and the first connection holes 12, the disassembly and assembly of the connecting seat 20 and the internal chill 10 are realized, so that the internal chill 10 can adapt to the assembly environment of different reserved holes.

[0043] Refer to the appendix Figures 1-6As shown, in some embodiments, the first connection hole 12 includes a limiting space 121 and a long slot 122. The long slot 122 communicates with the limiting space 121. The second connection hole 21 is a stepped hole. The fastener 30 includes a stepped rod 31, a limiting plate 32, and an elastic part 33. The stepped rod 31 is movably disposed in the stepped hole. The limiting plate 32 is disposed at one end of the stepped rod 31 close to the chill 10, and the limiting plate 32 extends into the long slot 122. The elastic part 33 abuts between the extrusion section of the stepped rod 31 and the compressed section of the stepped hole.

[0044] It should be noted that the extrusion section of the stepped rod 31 refers to the section with a larger diameter of the stepped rod 31; the compressed section of the stepped hole refers to the section with a larger diameter of the stepped hole.

[0045] Exemplarily, the elastic part 33 can be a spring or a rubber elastic ring, etc.

[0046] According to this embodiment, when the connecting seat 20 is assembled, the stepped rod 31 moves towards the limiting space 121, the elastic part 33 deforms gradually, and the limiting plate 32 gradually enters the limiting space 121 from the long slot 122. After the limiting plate 32 completely enters the limiting space 121, by rotating the stepped rod 31, the limiting plate 32 is fitted with the top wall of the limiting space 121 to realize the fastening of the connecting seat 20 and the chill 10. When disassembling and assembling the connecting seat 20, by rotating the stepped rod 31, the limiting plate 32 is aligned with the long slot 122, and then through the extension action of the elastic part 33, the limiting plate 32 can quickly withdraw from the limiting space 121. In this way, the time for repeatedly screwing bolts or screws can be saved, thereby improving work efficiency.

[0047] Refer to the attached Figure 1 and 4 As shown, in some embodiments, at least one pair of anti-rotation protrusions 22 are provided on the connecting seat 20, and each pair of anti-rotation protrusions 22 is axisymmetric about the central axis of the connecting seat 20.

[0048] According to this embodiment, after the connecting seat 20 is assembled with the reserved hole, the anti-rotation protrusions 22 generate a frictional effect with the hole wall of the reserved hole, which can improve the effect of preventing the chill 10 from rotating.

[0049] Refer to the attached Figure 5 As shown, in some embodiments, a plum blossom groove 311 is provided at one end of the stepped rod 31 far from the limiting plate 32.

[0050] According to this embodiment, it is convenient to apply force to the stepped rod 31.

[0051] Optionally, the chill 10 and / or the connecting seat 20 is made of stainless steel.

[0052] Exemplarily, the stainless steel material can be 303 stainless steel, etc.

[0053] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
