Description

Combined dental plate mould

The present invention relates to a combined dental plate mold, and more particularly to a combined dental plate mold for processing 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.

The guiding groove 226 has a wedge shape and is a conventional structure of the dental plate mold for positioning a screw to be processed.

Please refer to Figures 2 and 3, wherein Figure 3 is a plan view of a preferred embodiment of the combined dental plate mold of the present invention. When the two dental plate members 21 and 22 are installed in the accommodating space S of the fixing frame 1, the dental plate member 21 is disposed opposite to the dental plate member 22, and the two dental plate members 21 and 22 are disposed. The second bonding faces 214, 224 are attached to each other. The first positioning member 151 is screwed into the first positioning hole 141 to protrude into the accommodating space S and abuts the first abutting surface 211 of the dental plate member 21; the second positioning member 152 is screwed into the The second positioning hole 141 protrudes into the accommodating space S and abuts against the first abutting surface 221 of the plate member 22 . By continuously screwing the first positioning member 151 and the second positioning member 152 into the accommodating space S, the second abutting surface of the two dental plate members 21 and 22 can be forced. 221 and 222 are respectively abutted against the second side wall 13 to fix the two dental plate members 21 and 22 in the accommodating space S by the pressing method.

It is to be noted that the dental plate member 21 is fixed between the first positioning member 141 and the second side wall 13 , and the dental plate member 22 is fixed between the second positioning member 142 and the second side wall 13 . Therefore, the distance L1 between the first side wall 12 and the second side wall 13 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 first side wall 12 and The second side walls 13 are respectively fixed by the plurality of positioning members 14 . In addition, when the preferred embodiment of the combined dental plate mold of the present invention is actually used, the second bonding surface 213 of the two dental plate members 21 and 22 is respectively clamped by a conventional clamping machine with a clamp (not shown). 223, for fixing the combined dental plate mold to the boring machine. Therefore, the widest portion of the fixing frame, that is, the maximum width H1 of the bottom plate 11, the first side wall 12 and the second side wall 13 is preferably smaller than the total width H2 of the dental plate member set 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 can be located outside the accommodating space S, so as to prevent the clamp from improperly clamping the fixing frame 1, and cannot be sure The two plate members 21, 22 are clamped.

Referring to Figure 4, there is shown a use diagram of a preferred embodiment of the combined dental plate mold of the present invention. 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 first side wall 12 of the holder 1 with respect to the plurality of rib grooves 225. The first positioning member 151 is continuously rotated in the clockwise direction C to continuously rotate into the accommodating space S, so that the dental plate member 21 can be clamped by the first positioning member 151 and the second side wall 13 The force is greater than the force of the second plate member 152 and the second side wall 13 being sandwiched by the tooth plate member 22. Accordingly, the plurality of sipe grooves 215 can be slightly adjusted toward the second side wall 13 to align the plurality of ridges. Slot 225.

With the above structure, the two dental plate members 21, 22 of the preferred embodiment of the combined dental plate mold of the present invention are located in at least one positioning hole 14 through which the plurality of positioning members 15 are inserted and fixed to the plurality of positioning positions. The hole 14 can be fixedly fixed to the fixing frame 1 at the same time, and the relative position of the rib groove 215 and the rib groove 225 can be adjusted to move each of the rib grooves 215. The corresponding grooving grooves 225 are aligned to form a seamless continuous connection. Using a conventional boring machine, two sets of the combined stencil mold of the preferred embodiment of the present invention are respectively clamped by two clamps to form a counter-pressure, and a locating member to be processed is placed between the pair of pressed dies Pressing, it is possible to squeeze the ridges required to form the positioning member. In addition, since the clamp can firmly hold the first joint surface 213 of the dental plate member 21 and the first joint surface 223 of the dental plate member 22, the combined dental plate mold of the preferred embodiment of the present invention is finely adjusted to make each After the pair of ribs 215 are located in the corresponding ridges 225 and fixed to the conventional boring machine, the ridges 215 and the corresponding ridges 225 are no longer misaligned.

In summary, the combined dental plate mold of the present invention comprises a dental plate assembly 2, which 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 positioning member. Furthermore, although the combined dental plate mold of the present invention includes a plurality of dental plate members, the plurality of positioning members are used to adjust the relative positions between the plurality of dental plate members, thereby ensuring that the ridges of the dental plate members are aligned with each other. The seamless connection is formed, which can effectively improve the quality of the produced positioning parts compared with the conventional combined dental plate mold.

While the invention has been described in connection with the preferred embodiments described above, it is not intended to limit the scope of the invention. The technical scope of the invention is protected, and therefore the scope of the invention is defined by the scope of the appended claims.
