[0034] Reference Figures 2-9 As shown, a manufacturing mold with an inclined draft structure includes a shell mold 10. The shell mold 10 includes an upper mold and a lower mold corresponding to the upper mold. The upper mold includes a first shell 11, which includes a first mounting plate 111 and a first mounting block 112 connected to the first mounting plate 111. The first mounting plate 111 and the first mounting block 112 are fixed by bolts. A pouring gate is provided on the first mounting plate. A first receiving groove 1121 is provided in the first mounting block 112. An upper mold core 12 is provided in the first receiving groove 1121. A plurality of first grooves 121 are provided in the upper mold core 12. A first mounting groove 1122 is provided on the side wall of the first shell 11. The lower mold includes a second shell 11. 3. The second housing 13 includes a second mounting plate 131 and a second mounting block 132 fixedly connected to the second mounting plate 131. The second mounting plate 131 and the second mounting block 132 are fixed by bolts. The second mounting block 132 is provided with a second receiving groove 1321. The second receiving groove 1321 is provided with a lower mold core 14. The lower mold core 14 is installed in the second housing 13. The lower mold core 14 is provided with an injection part 141 corresponding to the first groove 121. The side wall of the second housing 13 is provided with a second mounting groove 1322 that is adapted to the first mounting groove 1122. When the upper mold and the lower mold are engaged, the first groove 121 and the injection part 141 are engaged to form an injection cavity. The pouring port penetrates the injection cavity for pouring.

[0035] Reference Figures 3-5As shown, the draft assembly 20 includes a first positioning block 21 that can be slidably disposed laterally within a second mounting groove 1322. A first sliding groove 1324 is provided at the bottom of the second mounting groove 1322. A first slider 212 corresponding to the sliding groove is provided at the bottom of the first positioning block 21. The first slider 212 is disposed within the first sliding groove 1324, allowing the first positioning block 21 to slide relative to the second mounting groove 1322. The first positioning block 21 is disposed within the first mounting groove 1322 and is tightly locked to the first housing 11. A second positioning block 22 that slides longitudinally relative to the first positioning block 21 is connected to the rear of the first positioning block 21. A longitudinal second slide groove 213 is provided behind a positioning block 21. The second positioning block 22 is provided with a second slider 222 corresponding to the second slide groove 213. The second slider 222 is slidably disposed in the second slide groove 213, so that the second positioning block 22 slides relative to the first positioning block 21. The second positioning block 22 is inclined. An injection block 221 is provided at the end of the second positioning block 22 away from the first positioning block 21. An inclined sliding groove 144 adapted to the second positioning block 22 is provided on the lower mold core 14. The second positioning block 22 is disposed in the inclined sliding groove 144. The injection block 221 is disposed in the injection cavity.

[0036] The demolding principle of this utility model is as follows: When the speaker housing is molded and cured, and demolding is required, the upper mold is first removed so that the first positioning block 21 can slide freely. The first positioning block 21 moves laterally away from the lower mold core 14. During this process, the second positioning block 22 moves downward relative to the first positioning block 21. The second positioning block 22 presses tightly against the inclined sliding groove 144, so that the second positioning block 22 moves downward at an angle, which facilitates smooth demolding and prevents product defects caused by demolding.

[0037] Reference Figures 3-5 As shown, the first positioning block 21 has a longitudinally penetrating inclined fixing groove 211 in the middle. An inclined mounting block 23 is slidably disposed in the inclined fixing groove 211. The bottom of the first mounting block 112 has a placement groove 1123 corresponding to the inclined mounting block 23. The inclined mounting block 23 is disposed in the placement groove 1123 and is locked and fixed to the first mounting block 112 with bolts. First, the first positioning block 21 is placed in the second mounting groove 1322, then the inclined mounting block 23 is placed in the placement groove 1123, and then the first mounting block 112 is placed above the second mounting block 132, so that the inclined mounting block 23 and the first positioning block 21 are accommodated in the mounting groove. The inclined mounting block 23 is locked and fixed to the first mounting block 112 with bolts. The advantage of this arrangement is that during injection molding, not only can the lateral movement of the first positioning block 21 be restricted, but also, because the inclined mounting block 23 is inclined, the longitudinal movement of the first mounting block 112 and the second mounting block 132 can be prevented.

[0038] Reference Figure 3 As shown, a transverse slot 1323 is provided in the second receiving groove 1321. Several first springs 15 are provided in the transverse slot 1323. The other end of the first spring 15 is connected to a positioning plate 16. Several positioning rods 17 are provided on the positioning plate 16. The lower mold core 14 is provided with a first positioning hole 142 corresponding to the positioning rod 17. The upper mold core 12 is provided with a second positioning hole 122 corresponding to the positioning rod 17. The lower mold core 14 presses tightly against the positioning plate 16, so that the positioning rod 17 passes through the first positioning hole 142 and is set in the second positioning hole 122. The positioning rod 17 can not only position the upper mold core 12 and the lower mold core 14, but also, the positioning rod 17 is set on one side of the second mounting plate 131, which can play a good role in preventing mistakes and preventing the upper mold core 12 and the lower mold core 14 from being installed in the wrong direction, resulting in waste of the speaker housing molding.

[0039] Reference Figure 5 As shown, a sliding groove 161 is provided horizontally on the positioning plate 16, and a sliding block 171 adapted to the sliding groove 161 is provided on the positioning rod 17. The sliding block 171 is disposed in the sliding groove 161. The positioning rod 17 can be adjusted in position according to the sliding groove 161, thereby adapting to upper mold core 12 and lower mold core 14 of different specifications.

[0040] The second housing 13 is provided with several spring assemblies 30. Each spring assembly 30 includes a positioning shaft and a disc spring disposed on the positioning shaft. The disc spring provides a certain buffer during the pressing process of the upper mold core 12 and the lower mold core 14, preventing deformation of the upper mold core 12 and the lower mold core 14. The first housing 11 is provided with several first through holes. The bottom of the lower mold core 14 is provided with several second through holes penetrating the injection part 141. The second housing 13 is provided with several ejector pins that are adapted to the first through holes and the second through holes. The ejector pins are disposed in the second through holes. During the demolding process, since the upper mold is the moving mold for demolding, the speaker housing is disposed on the lower mold core 14. By pressing the ejector pins, the speaker housing can be quickly demolded.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
