Description

Technical Field

[0001] The invention relates to the technical field of jewelry wax model tree production, in particular to a jewelry wax model tree positioning molding steel mold and a method thereof. Background Art

[0002] Planting the wax tree is the second step in jewelry lost wax casting. Planting the wax tree is to weld the prepared wax molds on a wax stick in layers along the circumferential direction in a certain order using an electric soldering iron. Finally, a wax mold tree shaped like a tree is obtained and the wax tree is then filled with plaster.

[0003] Under current conditions, artificial wax tree production is mostly done by first preparing the wax plates needed for batch production, then manually welding each wax ring to a wax stick, and finally getting a wax tree that looks like a big tree; put the planted wax tree and the chassis together with the stainless steel cylinder, and slowly inject the corresponding weight of gypsum slurry along the inner wall of the steel cylinder until it covers the wax tree, and then evacuate the wax and leave it naturally for 6-12 hours to allow the gypsum to solidify. For example, a jewelry processing equipment disclosed in the announcement number CN207272092U uses a pressure rod at the front end of a quick clamp to press and fix the wax model tree in a positioning plate. When the operator welds the wax model on the wax rod, the structure is movable and adjustable, which is convenient for the operator to adjust the inclination angle of the wax rod when welding the wax model; similarly, a jewelry lost wax casting method disclosed in the announcement number CN114769510B has openings at both ends of the steel cup to facilitate the ejection of the plaster jewelry rough piece in the steel cup, and a limit ring is provided to facilitate the hanging of the steel cup on the box frame. The bases of the two are connected with each other. A fixed single-point connection structure is adopted between the wax trees, and the height of the wax trees is much higher than the base. When the former connects the mold tube on the base to fit the wax tree, due to the lack of support and limiting effect between the wax tree and the mold tube, the gypsum slurry poured into the mold tube will impact and squeeze the wax tree and the wax mold, which can easily cause the wax tree and the wax mold to tilt, displace or even separate, thereby affecting the quality of gypsum molding; the latter hangs a steel cup on the steel cylinder, which is flexible and convenient, but it is difficult to ensure the stability of the entire steel cup, especially when the gypsum has not yet solidified and formed, it is easy to cause structural changes, and the structural differences will also have a negative impact on the later demolding. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that the fixed structure of the jewelry wax tree affects the level of plaster molding and demoulding, and to propose a jewelry wax model tree positioning molding steel mold and method.

[0138] The second internal thread 70403 is integrally arranged on the inner wall of the limiting tube 70401 , and the second internal thread 70403 is meshedly connected with the second external thread 709 by screwing the booster 704 .

[0139] The annular wedge plate 70404 is integrally connected to the lower end of the shrink sleeve 70402 . The annular wedge plate 70404 moves downward with the spiral of the booster 704 , thereby applying progressive pressure to the wedge opening 70805 of the locking member 708 , so that the locking member 708 extends further into the heightening boss 702 .

[0140] On the other hand, the locking member 708 includes a telescopic outer rod 70801 and a telescopic inner rod 70802 corresponding to the locking opening 707, a limiting flange 70803 and a strong spring 70804, and a wedge opening 70805 of a sliding sleeve annular wedge plate 70404:

[0143] The wedge opening 70805 is provided in the outer end of the telescopic outer rod 70801 outside the receiving through hole 706. Figure 8 With attached Fig. 9 The wedge opening 70805 is matched with the annular wedge plate 70404. The annular wedge plate 70404 can be used to apply pressure to the wedge opening 70805. Under the elastic support of the strong spring 70804, the locking member 708 tends to extend outward from the heightened boss 702.

[0144] It should be noted that the specific models and specifications of the limiting base 1 and the wax tree wax stick 5 need to be selected and determined according to the actual specifications of the device, and the specific selection and calculation method adopts the existing technology in this field, so it is not repeated here.

[0145] The present invention can be explained by the following operation mode:

[0146] The first step is to vertically fit the bottom end of the wax tree wax stick 5 on the sunken mouth 701, the heightening boss 702 and the limiting column 703, and then fit the booster 704 on the heightening boss 702 and the limiting column 703 through the wax tree wax stick 5, and rotate the booster 704 on the heightening boss 702 and the limiting column 703, so that the second internal thread 70403 is meshed and connected with the second external thread 709, and the annular wedge plate 70404 in the booster 704 rotates in the wedge opening 70805 in the locking member 708, and squeezes the telescopic outer rod 70801 and the strong spring 70804, so that the telescopic inner rod 70802 extends from the receiving through hole 706 to the locking mouth 707. It should be noted that when the booster 704 moves up and down in the spiral, the annular wedge plate 70404 is always movably fitted in the wedge opening 70805;

[0147] The second step is to open an oblique hole 601 on the wax tree wax stick 5, and obliquely insert the isotropic wax rod 602 into the oblique hole 601 to fix the isotropic ring 603 and the heightening frame 604, so as to set the required number of wax molds 6 on the wax tree wax stick 5;

[0148] The third step is to sleeve the mold tube 3 on the load-bearing base 2 so that the top of the wax tree wax stick 5 is sleeved in the lower sealing ring groove 803 of the inner bracket 802, and the load-bearing base 2 and the mold tube 3 are rotated in the opposite direction so that the third internal thread 805 is meshed and connected with the third external thread 806, so as to realize the combined connection between the load-bearing base 2 and the mold tube 3, and the wax tree wax stick 5 and the wax mold 6 are sleeved in the mold tube 3;

[0149] Step 4: Using the inner bracket 802 as a fulcrum, screw the reinforcing member 4 so that the lengthened threaded rod 401 extends into the recessed opening 701, so that the first inner thread 705 is meshed with the first outer thread 710 to strengthen and fix the wax tree and wax stick 5 from the inside.

[0150] The fifth step is to push the boost column 901 into the lower opening 905 to squeeze the driving piston 911 and the return spring 910, so as to squeeze the driven piston 912, so that the locking plug 913 extends from the sealing cavity 907 to the locking socket 904, and drive the load-bearing base 2 and the mold tube 3 to rotate 45° clockwise or counterclockwise, so that the limit baffle 908 is deflected to the position corresponding to the limit pressure plate 902, and under the tension of the return spring 910, the limit plug 903 is installed in the limit socket 909, which can prevent the load-bearing base 2 from rotating and causing it to separate from the limit base 1.

[0151] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
