[0039] Please refer to Figure 1 and Figure 2 simultaneously. Now, the positioning member for a double-cavity mold provided by the present application will be described. For the positioning member for a double-cavity mold, the double-cavity mold 8 has two symmetrically arranged mold cavities; it is characterized in that the positioning member includes a fixture body 1 coaxially arranged on a lathe 9; the fixture body 1 has an installation groove 2 eccentrically arranged with it and used for embedding the double-cavity mold 8; the bottom of the installation groove 2 has an alignment hole 3 coaxially arranged with the fixture body 1, and also has a ring platform 31 coaxially arranged with the alignment hole 3 and used for embedding into the mold cavity.

[0040] Among them, when the double-cavity mold 8 is embedded in the installation groove 2, the annular platform 31 can be inserted into one of the mold cavities and abutted against the inner peripheral wall of the mold cavity, so that the mold cavity is coaxially arranged with the alignment hole 3.

[0041] In the embodiment of the present application, the fixture body 1 is provided with an eccentrically arranged installation groove 2 for one end of the double-cavity mold 8 to be embedded. By coaxially installing the fixture body 1 on the chuck 9 of the lathe and embedding one end of the double-cavity mold 8 into the installation groove 2, the quick clamping of the double-cavity mold 8 can be completed, and the operation is simple, time-saving and labor-saving; moreover, when the double-cavity mold 8 is embedded in the installation groove 2, the annular platform 31 is inserted into one of the mold cavities on the double-cavity mold 8, and the quick centering of the mold cavity to be processed can be realized, and this operation process is also time-saving and labor-saving.

[0042] Compared with the prior art, the positioning member for the double-cavity mold provided by the embodiment of the present application can realize the quick clamping of the double-cavity mold 8 during the turning process of the double-cavity mold 8, and can respectively and accurately realize the centering adjustment of the two mold cavities, which is time-saving and labor-saving and improves the processing efficiency.

[0043] In some embodiments, please refer to Figures 3 to 5 together, as a specific implementation manner of the positioning member for the double-cavity mold provided by the present application, the positioning member further includes a plurality of counterweight blocks 4.

[0044] The plurality of counterweight blocks 4 are all arranged on the fixture body 1, and each counterweight block 4 is arranged side by side with the installation groove 2.

[0045] By adopting the above technical solution, the weight and number of the counterweight blocks 4 can be adjusted according to the weight of the double-cavity mold 8 to be processed, and the purpose is to balance the centrifugal force generated by the eccentric rotation of the eccentrically arranged double-cavity mold 8 during the turning process.

[0046] In some embodiments, please refer to Figures 1 to 5 together, as a specific implementation manner of the positioning member for the double-cavity mold provided by the present application, the counterweight block 4 has a plurality of countersunk holes 41, and the fixture body 1 has threaded grooves 11 corresponding to the plurality of countersunk holes 41 one by one; each countersunk hole 41 is inserted with a fastening bolt 42, and each fastening bolt 42 is respectively threadedly connected with the corresponding threaded groove 11.

[0047] By adopting the above technical solution, the countersunk holes 41 are provided so that when replacing the counterweight blocks 4 with different weights, only the depth of the countersunk holes 41 on different counterweight blocks 4 needs to be kept consistent, and the fastening bolts 42 do not need to be replaced.

[0048] In some embodiments, please refer to Figure 6 and Figure 7, as a specific implementation manner of the positioning member for the double-cavity mold provided in the present application, the insertion end of the annular platform 31 adopts a conical structure.

[0049] By adopting the above technical solution, during the process of embedding the double-cavity mold 8 into the installation groove 2 at the end, the conical surface on the outer wall of the annular platform 31 will first contact the inner wall of the mold cavity, thereby providing a guiding effect for the movement of the double-cavity mold 8, increasing the error tolerance during centering, and making the clamping process of the double-cavity mold 8 more convenient.

[0050] In some embodiments, please refer to Figures 1 to 4 , as a specific implementation manner of the positioning member for the double-cavity mold provided in the present application, the inner peripheral wall of the installation groove 2 has an anti-slip coating 21.

[0051] By adopting the above technical solution, the anti-slip coating 21 can increase the friction force between the inner wall of the installation groove 2 and the outer wall of the double-cavity mold 8, greatly reducing the risk of the double-cavity mold 8 disengaging from the installation groove 2.

[0052] In some embodiments, please refer to Figure 5 , as a specific implementation manner of the positioning member for the double-cavity mold provided in the present application, the fixture body 1 has a strip-shaped notch 5 that penetrates axially along the installation groove 2, and an adjustment assembly 7 that restricts the opening of the strip-shaped notch 5; wherein, the strip-shaped notch 5 extends radially along the installation groove 2 and communicates with the installation groove 2.

[0053] By adopting the above technical solution, the strip-shaped notch 5 and the adjustment assembly 7 can make the size of the installation groove 2 adjustable; when turning the double-cavity mold 8 is required, first adjust the adjustment assembly 7 to increase the opening amplitude of the strip-shaped notch 5, thereby increasing the inner diameter of the installation groove 2, then embed the end of the double-cavity mold 8 into the installation groove 2, and finally adjust the adjustment assembly 7 to reduce the opening amplitude of the strip-shaped notch 5, thereby reducing the inner diameter of the installation groove 2 to clamp the outer wall of the double-cavity mold 8; the adjustment assembly 7 and the strip-shaped notch 5 can achieve the purpose of quickly clamping the double-cavity mold 8.

[0054] It should be added that due to the existence of the strip-shaped notch 5, the above-mentioned annular platform 31 and anti-slip coating 21 are divided into two parts along the middle; the above-mentioned counterweight 4 can be multiple small counterweights 4, which are symmetrically arranged on both sides of the strip-shaped notch 5 respectively.

[0055] In some embodiments, please refer to Figure 6 and Figure 7 , as a specific implementation manner of the positioning member for the double-cavity mold provided in the present application, the strip-shaped notch 5 internally has a plurality of bosses 51 that extend axially along the installation groove 2 and are perpendicular to the side wall of the strip-shaped notch 5, and a plurality of grooves 52 for the plurality of bosses 51 to be correspondingly embedded; the distance between the bosses 51 and the grooves 52 is consistent with the width of the strip-shaped notch 5.

[0056] It should be noted that when the length of the strip-shaped notch 5 is too long, during the use of the fixture body 1, the parts of the fixture body 1 on both sides of the strip-shaped notch 5 are prone to relative swing along the axis direction of the fixture body 1.

[0057] Since both the convex platform 51 and the concave groove 52 are perpendicularly arranged relative to the side wall of the strip-shaped notch 5, when the parts of the fixture body 1 on both sides of the strip-shaped notch 5 swing relatively along the axis direction of the fixture body 1, the outer wall of the protrusion will abut against the inner wall of the concave groove 52, thereby preventing the swing from continuing; by adopting the above technical solution, the cooperation between the protrusion and the concave groove 52 can control the swing range within a reasonable range and improve the clamping accuracy of the fixture.

[0058] In some embodiments, please refer to Figures 1 to 4 , as a specific implementation manner of the positioning member for the double-cavity mold provided in this application, the fixture body 1 has two protruding parts 6 arranged side by side in the radial direction of the installation groove 2, and the arrangement direction of the two protruding parts 6 is perpendicular to the extension direction of the strip-shaped notch 5; a gap between the two protruding parts 6 communicates with the strip-shaped notch 5; each protruding part 6 has a through hole 61, and the two through holes 61 are coaxially connected; the adjusting assembly 7 includes an adjusting bolt 71 and an adjusting nut 72.

[0059] The adjusting bolt 71 is inserted into the mutually connected through holes 61; the adjusting nut 72 is threadedly connected to the adjusting bolt 71; wherein, the number of the adjusting bolts 71 and the adjusting nuts 72 can be increased or decreased according to the size of the protruding part 6.

[0060] Wherein, the head of the adjusting bolt 71 and the adjusting nut 72 respectively abut against the two protruding parts 6 to limit the opening of the strip-shaped notch 5 and cause the fixture body 1 to generate elastic deformation to adjust the size of the strip-shaped notch 5.

[0061] By adopting the above technical solution, by loosening or tightening the adjusting nut 72, the distance between the adjusting nut 72 and the adjusting bolt 71 can be increased or decreased, thereby increasing or decreasing the size of the opening of the strip-shaped notch 5.

[0062] In some embodiments, please refer to Figure 5 , as a specific implementation manner of the positioning member for the double-cavity mold provided in this application, there is a notch 62 penetrating along the axis direction of the installation groove 2 between the two protruding parts 6, and the notch 62 communicates with the strip-shaped notch 5.

[0063] By adopting the above solution, when the clamping operation of the double-cavity mold 8 needs to be performed, a tool can be inserted into the notch 62 first, and then the two convex parts 6 can be pried to increase the distance between the two convex parts 6, so as to increase the opening of the strip-shaped notch 5, and further increase the inner diameter of the installation groove 2, facilitating the insertion of the double-cavity mold 8 into the installation groove 2.

[0064] The technical solution adopted in this application also provides a turning machine tool, including the positioning member for the double-cavity mold proposed in any one of the foregoing.

[0065] The beneficial effects of the turning machine tool provided in this embodiment are the same as those of the foregoing positioning member for the double-cavity mold, and will not be elaborated here.

[0066] The above are only the preferred embodiments of this application, and are not intended to limit this application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of this application shall be included in the protection scope of this application.
