Description

Combined dental plate mould

This creation is directed to a combination dental plate mold, and more particularly to a combined dental plate mold for machining a screw to form a thread.

The conventional screw manufacturing method uses a conventional dental plate mold to hold a screw to be processed, and is rolled on the outer edge of the round bar material to form a spirally extending convex tooth pattern to produce a desired screw product. Wherein, the dental plate mold comprises a plurality of obliquely extending rib grooves for pressing to form a ridge protruding from the outer edge of the screw, and the sequence of contact between the rib groove and the screw to be processed is different due to operation, resulting in proximity The ridge groove at the specific end of the dental plate mold is relatively easy to lose. However, once some of the sipe grooves are damaged, it is necessary to replace the entire slab mold, which greatly increases the manufacturing cost.

In order to solve the above problem, please refer to FIG. 1 and the Republic of China Announcement No. M345667, which discloses a conventional combination dental plate mold 9, which comprises a dental plate mold 91 and a dental plate head 92.

Please refer to the fourth and fifth figures, which is a schematic diagram of a preferred embodiment of the present combined dental plate mold which is actually installed in a conventional boring machine M. The tamper M can hold the combined stencil mold with a clamp C to fix it to the squeegee M. In detail, the clamp C has a clamping surface C1, and the first positioning member 141 and the second positioning member 142 are continuously screwed in, respectively. The accommodating space S can force the second abutting surfaces 212 and 222 of the two dental plate members 21 and 22 to abut against the clamping surface C1 to fix the two dental plate members 21 and 22 by pressing. In the accommodation space S and the clamp C. In addition, the clamp C can clamp the first joint surfaces 213 and 223 of the two tooth plate members 21 and 22 through a clamping member C2 and a baffle C3 to further position the combined dental plate mold.

Please refer to FIG. 6 , which is a use diagram of a preferred embodiment of the present combined dental plate mold. In an ideal state, when the two dental plate members 21 and 22 are firmly fixed in the accommodating space S, the rib grooves 215 of the dental plate member 21 should be corresponding to the corresponding dental plate members 22, respectively. The grooving grooves 225 are aligned in order to form a seamless continuous connection. However, there may be tolerances in the production process of the two dental plates 21, 22 such that the ridges 215 and the corresponding ribs 225 are misaligned. For example, the plurality of rib grooves 215 as shown in the figure are slightly offset from the side wall 12 of the holder 1 with respect to the plurality of rib grooves 225. By rotating the first positioning member 141 to continuously screw it into the accommodating space S, the force of the dental plate member 21 being clamped by the first positioning member 141 and the clamping surface C1 can be compared with the dental plate. The force of the piece 22 being clamped by the second positioning member 142 and the clamping surface C1 is large. Accordingly, the plurality of rib grooves 215 can be slightly adjusted toward the clamping surface C1 to align the plurality of rib grooves 225, and as shown in FIG. 7, each of the ridge grooves 215 are located oppositely. Corresponding to the rib groove 225.

More specifically, when the preferred embodiment of the present combination dental plate mold is mounted on the boring machine M, the positioning member 14 and the clamping surface C1 of the clamp C can be used to respectively fix and fix the dental plate assembly. 2, and the clamping member C2 can further position the dental plate member set 2 via the baffle C3. When the user completes the fine adjustment of the dental plate assembly 2 by rotating the positioning member 14, it is ensured that the ridges 215, 225 of the respective dental plate members 21, 22 in the dental plate assembly 2 are accurately aligned with each other. The clamping member C2 can be controlled (for example, screwed) to strengthen the clamping positioning force of the dental plate member set 2, thereby firmly clamping the first bonding surface 213 of the dental plate member 21 and the dental plate member 22 The first bonding surface 223 is such that the ridge groove 215 and the corresponding rib groove 225 are no longer generated. Misplaced situation.

It is to be noted that the dental plate member 21 is fixed between the first positioning member 141 and the clamping surface C1, and the dental plate member 22 is fixed between the second positioning member 142 and the clamping surface C1. Therefore, the distance L1 between the side wall 12 and the clamping surface C1 is greater than the length L2 of the two dental plate members 21, 22, so that the two dental plate members 21, 22 can be placed on the side wall 12 and the clamping surface C1. Between the two, the plurality of positioning members 14 are respectively fixed and fixed. In addition, when the preferred embodiment of the present combination dental plate mold is actually used, the second bonding surfaces 213 and 223 of the two dental plate members 21 and 22 are respectively clamped by the conventional clamping machine M for fixing. The combined dental plate mold is applied to the dentition machine. Therefore, the widest portion of the fixing frame 1, that is, the maximum width H1 of the bottom plate 11 and the side wall 12, is preferably smaller than the total width H2 of the dental plate member group 2. Thereby, the first bonding surface 213 of the dental plate member 21 and the first bonding surface 223 of the dental plate member 22 are located outside the accommodating space S, so as to prevent the clamp C from improperly clamping the fixing frame 1, and cannot The two dental plates 21, 22 are indeed clamped.

With the above structure, the two dental plate members 21 and 22 of the preferred embodiment of the combination dental plate mold are located in at least one positioning hole 13 through which the plurality of positioning members 14 are inserted and fixed to the plurality of positioning positions. The hole 13 can be respectively clamped by the positioning member 14 and the clamping surface C1 of the clamp C to fix the two dental plate members 21 and 22 to the fixing frame 1 respectively. At the same time, the relative positions of the sipe 215 and the sipe 225 can be adjusted to align the rib grooves 215 with the corresponding rib grooves 225 to form a seamless connection. Using the conventional boring machine M, the two sets of the combined stencil molds of the preferred embodiment of the present invention are respectively clamped by the clamp C and formed into a counter pressure, and a screw to be processed is placed between the combined dies of the pair of pressing dies. Pressing, it is possible to squeeze the ridges required to form the screw.

In summary, the creative combination dental plate mold comprises a dental plate assembly 2, and the dental plate assembly 2 comprises a plurality of dental plate members, and if one of the dental plate members is excessively worn during the processing of the positioning member, it needs to be replaced. It is only necessary to replace the damaged tooth plate member to be used normally, and the remaining intact dental plate member can be retained, thereby effectively reducing the manufacturing cost of the dental plate member group 2. Furthermore, the creative combination dental plate mold Although a plurality of dental plate members are included, the relative positions between the plurality of dental plate members are adjusted through a plurality of positioning members, so that the ridge grooves of the dental plate members can be aligned with each other to form a seamless connection. Compared with the conventional combination dental plate mold, the quality of the produced positioning parts can be effectively improved.

Although the present invention has been disclosed by the above-described preferred embodiments, it is not intended to limit the present invention, and it is still within the spirit and scope of the present invention to make various changes and modifications to the above embodiments. The technical scope of the protection is created, so the scope of protection of this creation is subject to the definition of the patent application scope attached.
