[0026] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model.

[0027] In the description of the present utility model, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality of" means two or more unless otherwise specifically defined.

[0028] Referring to Figures 1-2 As shown, a manufacturing mold for a speaker housing with a cooling function includes: a housing mold 10, including an upper mold 11 and a lower mold 12 corresponding to the upper mold 11. The upper mold 11 includes a first housing 111, an injection port is provided at the top of the first housing 111, an upper mold core 112 is installed in the first housing 111, and a number of first grooves 1121 are provided in the upper mold core 112. In this embodiment, the number of the first grooves 1121 is 2. The lower mold 12 includes a second housing 121, a lower mold core 122 is installed in the second housing 121, and an injection part 123 corresponding to the first grooves 1121 is provided in the lower mold core 122. When the upper mold 11 and the lower mold 12 are buckled, the first grooves 1121 and the injection part 123 are buckled to form an injection cavity.

[0029] Referring to Figures 1-2 As shown, a number of first through holes 1122 are provided on the side wall of the upper mold core 112, the first through holes 1122 communicate with the first grooves 1121, and a number of locking blocks 1111 are installed on the first housing 111. In this embodiment, the number of the locking blocks 1111 is 4, the locking blocks 1111 are fixed by bolts, an injection block is installed on the locking blocks 1111, a locking part 1112 is provided at the end of the injection block, the injection block passes through the through hole so that the locking part 1112 is arranged in the first groove 1121. During the injection process, due to the high injection conditions required for the locking part 1112 and the need to adjust the shape and specifications of the locking part 1112, the locking part 1112 needs to be formed by a separate mold core.

[0030] A number of spring assemblies 124 are provided on the second housing 121. The spring assemblies 124 include positioning shafts and disc springs 1241 provided on the positioning shafts. The disc springs 1241 provide a certain buffer during the pressing process of the upper mold core 112 and the lower mold core 122, preventing deformation of the upper mold core 112 and the lower mold core 122. A number of second through holes 1221 penetrating the injection part 123 are provided at the bottom of the lower mold core 122. A number of ejector pins 1211 adapted to the second through holes 1221 are provided on the second housing 121. The ejector pins 1211 are arranged in the second through holes 1221. During the demolding process, since the upper mold 11 is used as the moving mold to separate, the speaker housing is arranged on the lower mold core 122. By pressing the ejector pins 1211, the speaker housing can be quickly separated.

[0031] The core-pulling assembly 20 includes a positioning block 21 provided on the side wall of the upper mold 11. One end of the positioning block 21 away from the upper mold 11 is provided with a cylinder 22. The cylinder 22 is connected to a moving block 23 slidably arranged on the positioning block 21. The other end of the moving block 23 is connected with a number of core-pulling shafts 24. The core-pulling shafts 24 are arranged in the injection cavity. A circulation pipeline 25 is arranged in the core-pulling shafts 24. Cooling circulating water is arranged in the circulation pipeline 25. The cooling circulating water is supplied through the circulation pipeline 25 to connect to an external water source. Since the supply method of the external water source is a prior art, no more details are described here. During the injection process, the cooling circulating water can play a role in quickly cooling the core-pulling shafts, and then can quickly cool the speaker housing, enabling the speaker housing to be quickly demolded and improving the manufacturing efficiency of the speaker housing.

[0032] Refer to Figures 3-6 As shown, in this embodiment, the length of the core-pulling shaft 24 is 260 - 290 mm. Further, the length of the core-pulling shaft 24 is 262 mm. The diameter of the end of the core-pulling shaft 24 close to the moving block 23 is 17 mm. The core-pulling shaft 24 has an inward draft angle α = 0.5 - 1.5°. The core-pulling shaft 24 has an inward draft angle α = 0.5°. Therefore, the diameter of the end of the core-pulling shaft 24 is 13.6 mm. The advantage of such a setting is that, on the one hand, since the cooling circulating water flows through the internal circulation pipeline 25 of the core-pulling shaft 24 to cool the speaker housing, and since the diameter of the end of the core-pulling shaft 24 is small, the temperature at the end of the core-pulling shaft 24 is low, and the temperature inside the speaker housing cools quickly. During the demolding process, it is convenient for the core-pulling shaft 24 to be pulled out. On the other hand, since the diameter of the end of the core-pulling shaft 24 is small, the holes inside the speaker housing are small, which is convenient for clamping.

[0033] The positioning block 21 is provided with an installation groove 211, and both sides of the bottom of the installation groove 211 are provided with sliding grooves 212. The moving block 23 is provided with sliding blocks 231 corresponding to the sliding grooves 212. The sliding blocks 231 are slidably arranged in the sliding grooves 212, so that when the cylinder 22 drives the moving block 23 to perform core pulling backward, the operation is more stable, preventing the core pulling from affecting the molding of the speaker housing.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
