[0030] The following description, in conjunction with the accompanying drawings, describes a mold for manufacturing a wax mold for a face mask frame according to an embodiment of the present invention.

[0031] This utility model aims to provide an embodiment of a mold for manufacturing wax molds for mask frames.

[0032] In the structure of the mask frame 100, refer to Figure 1 The mask frame 100 includes a contour frame 110 and two face frames 120 connected to the contour frame 110. The two face frames 120 are distributed in the left and right direction within the contour frame 110. The left and right sides of the contour frame 110 have first connecting portions 130, and the first connecting portions 130 are provided with first mounting holes 140. The top side of the contour frame 110 has a second connecting portion 150, and the second connecting portion 150 is provided with a second mounting hole 160 and a third mounting hole 170. The second mounting hole 160 is on a first plane and on a second plane. The first plane and the second plane are arranged at 90°.

[0033] Understandably, the first mounting hole 140, the second mounting hole 160, and the third mounting hole 170 of the mask holder 100 are used to connect to the mounting position of the helmet.

[0034] This utility model provides a mold for manufacturing a wax model of a mask frame 100, referring to... Figure 2 It includes an upper mold 180, a first middle mold 190, a second middle mold 200 and a lower mold 210. The first middle mold 190 and the second middle mold 200 are arranged opposite to each other. A cavity is formed between the upper mold 180, the first middle mold 190, the second middle mold 200 and the lower mold 210. The cavity is used to form a wax model of the mask frame 100.

[0035] Because the outline frame 110 and the two face outline frames 120 have complex shapes and are all curved structures, the upper mold 180, the first middle mold 190, the second middle mold 200 and the lower mold 210 are used to form a cavity. Wax liquid is injected into the cavity, and after the wax liquid cools, it forms a wax model of the mask frame 100. The upper mold 180, the first middle mold 190 and the second middle mold 200 are separated, and the wax model of the mask frame 100 can be taken out from the lower mold 210. The mask frame 100 does not need to be manufactured by welding, which improves the consistency of the shape and size of each mask frame 100 and reduces the defects of the mask frame 100.

[0036] Furthermore, a first insert 230 is provided between the first middle mold 190 and the lower mold 210, and a second insert 240 is provided between the second middle mold 200 and the lower mold 210. Both the first insert 230 and the second insert 240 have a first core-pulling portion 220, which is used to form a first mounting hole 140.

[0037] Furthermore, referring to Figure 6 The upper mold 180 has a second core-pulling portion 250, which is used to form a second mounting hole 160. The lower mold 210 is provided with a third insert 260, which has a third core-pulling portion 270, which is used to form a third mounting hole 170.

[0038] Therefore, both the first insert 230 and the second insert 240 have a first core-pulling portion 220, which is inserted into the cavity to form a first mounting hole 140 for the wax model of the mask frame 100. The upper mold 180 has a second core-pulling portion 250, which is inserted into the cavity to form a second mounting hole 160 for the wax model of the mask frame 100. The third insert 260 has a third core-pulling portion 270 to form a third mounting hole 170 for the wax model of the mask frame 100. This ensures that the positions of the first mounting hole 140, the second mounting hole 160, and the third mounting hole 170 of each mask frame 100 are accurate, and that the mounting holes of the mask frame 100 can be well matched with the mounting position of the helmet.

[0039] In some embodiments of this utility model, reference is made to Figure 3 The lower mold 210 includes a first lower module 280 and a second lower module 290, which are arranged opposite to each other and are connected by a first bolt.

[0040] Understandably, due to the complex structure of the mask frame 100, the first lower module 280 and the second lower module 290 are designed as separate parts. The lower mold 210 is composed of the first lower module 280 and the second lower module 290. After the first lower module 280 and the second lower module 290 are manufactured separately, they are connected and fixed by the first bolt, thereby reducing the manufacturing difficulty of the lower mold 210.

[0041] In some embodiments of this utility model, reference is made to Figure 4 and Figure 5 The first lower module 280 is provided with a first through hole 300, and a fourth insert 310 is installed in the first through hole 300. The first through hole 300 is located close to the first insert 230.

[0042] Since the structure of the first connecting part 130 is relatively complex, the manufacturing difficulty of the first lower module 280 is reduced by setting a fourth insert 310, which is fixed to the first lower module 280 through the first through hole 300.

[0043] Similarly, the second lower module 290 is provided with a second through hole, and a fifth insert is installed in the second through hole. The second through hole is located close to the second insert 240.

[0044] In some embodiments of this utility model, the fourth insert 310 is provided with a square portion 340, and the first through hole 300 has a positioning section 350 that matches the square portion 340.

[0045] It is understandable that the outer dimensions of the square part 340 are larger than those of the fourth insert 310. Positioning the square part 340 in the positioning section 350 of the first through hole 300 can improve the installation accuracy of the fourth insert 310.

[0046] In some embodiments of this utility model, the first lower module 280 has a first guide groove 360, and the first insert 230 is slidably disposed in the first guide groove 360; the second lower module 290 has a second guide groove 370, and the second insert 240 is slidably disposed in the second guide groove 370.

[0047] Therefore, the first insert 230 can slide in the first guide groove 360, and the second insert 240 can slide in the second guide groove 370, so that the first insert 230 and the second insert 240 can be smoothly molded or demolded.

[0048] In some embodiments of this utility model, both the first insert 230 and the second insert 240 are provided with a hand grip 380, thereby facilitating the demolding and removal of the first insert 230 and the second insert 240.

[0049] In some embodiments of this utility model, the first intermediate mold 190 and the second intermediate mold 200 are both provided with a positioning part 390 on the side near the upper mold 180, and the upper mold 180 is provided with a positioning groove 400 that cooperates with the positioning part 390. Therefore, the positioning part 390 and the positioning groove 400 cooperate to position, ensuring that the first intermediate mold 190 and the second intermediate mold 200 are accurately molded together.

[0050] In the description of this specification, references to terms such as "an embodiment," "some embodiments," "illustrative embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0051] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
