Description

Technical Field

[0001] This utility model relates to the field of Bluetooth headset technology, and in particular to a mold for producing Bluetooth headset shells. Background Technology

[0002] Bluetooth earphone shells are outer shells that enclose the earphone's sound unit, battery, and other components. They are mostly made of ABS, PC, and other plastic materials through injection molding, serving both to protect the internal components and for aesthetic purposes. Their appearance is often treated with processes such as frosting and high gloss. Some high-end models will use metal or ceramic materials. They need to meet requirements such as lightweight, drop resistance, and acoustic structural compatibility, and are an important carrier for the industrial design and functional realization of earphones.

[0003] A search revealed that the document with publication number "CN216001179U" states that "this utility model relates to the field of mold technology, specifically to a mold for producing Bluetooth headset shells with a buffer function, including a main mold chamber. The main mold chamber has symmetrically opened grooves inside. A first fixing rod is inserted into the grooves inside the main mold chamber. Buffer supports are symmetrically sleeved on the surface of the first fixing rod. The buffer supports are slidably connected to the grooves inside the main mold chamber. A first spring is sleeved on the surface of the first fixing rod, and both ends of the first spring are welded to the inner wall of the main mold chamber and the surface of the buffer supports, respectively." In use, this utility model, through its structure, enables the stamping mold used for the Bluetooth headset shell to play a certain buffering role during the stamping process, thereby reducing the internal damage to the mold caused by the large impact force generated during mold use. Simultaneously, it can accelerate demolding and storage inside the mold after a single molding process, thus accelerating production efficiency.

[0004] However, in the production process of Bluetooth headset shells, most existing molds use casting molds. However, during the casting process, the internal temperature of the mold is high, the cooling is slow, and natural cooling and demolding are difficult, which can easily lead to shell damage and make it difficult to remove the shell from the mold. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a mold for producing Bluetooth headset shells, aiming to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A mold for producing Bluetooth headset shells includes a fixed base, an headset shell production assembly on the upper side of the fixed base, a sliding groove on the inner side of the fixed base, a movable slider installed on the inner side of the sliding groove, a casting tank welded to the upper side of the movable slider, tank guide pipes installed at both ends of the inner side of the casting tank, a casting liner in the middle of the tank guide pipes, a fixing groove welded to the upper side of the casting tank, a top cover installed on the upper side of the fixing groove, an extrusion shaping block on the inner side of the casting liner, a glue injection port on the upper side of the top cover, an exhaust port on the opposite side of the glue injection port, and a shaping block guide pipe on the inner side of the extrusion shaping block.

[0008] Furthermore: the movable slider and the slide groove are connected by a slot, the movable slider and the slide groove are tightly fitted together, and the movable slider is arranged in four groups.

[0009] Furthermore: the tank guide pipe is located between the casting tank and the casting inner liner, and the tank guide pipe has a honeycomb structure.

[0010] Furthermore: a lifting diaphragm is bonded to the lower inner end of the casting liner, an air rod is connected to the lower side of the lifting diaphragm, an air inlet pipe is connected to the lower side of the air rod, the lifting diaphragm is made of silicone rubber, and the lifting diaphragm forms a lifting structure through the air rod.

[0011] Furthermore: the upper cover and the fixing slot are connected by a slot, the upper cover and the fixing slot fit tightly together, and there is a one-to-one correspondence between the upper cover and the fixing slot.

[0012] Furthermore: the extrusion molding block and the top cover are welded together, and a casting gap is left between the extrusion molding block and the casting inner liner. The vent and the glue injection port are used for glue injection through the casting gap between the extrusion molding block and the casting inner liner.

[0013] Furthermore: the shaping block guide tubes are arranged in two groups, left and right, about the extrusion shaping block, and the two groups of extrusion shaping blocks are connected by pipes, and the shaping block guide tubes have a honeycomb structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By setting up the headphone shell production assembly, after the casting is completed and solidified, gas is injected into the air rod through the air inlet pipe. As the air rod rises, the lifting film will push the headphone shell out of the casting inner cylinder, achieving rapid demolding. The extrusion shaping block is inserted into the inside of the casting inner cylinder through the top cover. At this time, the plastic solution is injected into the gap between the casting inner cylinder and the extrusion shaping block through the injection port, and the air is discharged through the vent to ensure that the plastic solution is evenly filled. After cooling and solidification, the extrusion shaping block is tightly bonded to the headphone shell, improving molding accuracy and structural stability.

[0016] 2. By setting up the headphone shell production assembly, when needed, after the casting of the inner liner in the casting tank is completed, coolant can be poured into the honeycomb structure of the tank's guide pipe, thereby reducing the surface temperature of the inner liner. This not only accelerates the solidification speed but also makes the surface of the solidified headphone shell smoother and more delicate, and facilitates demolding. Furthermore, the coolant is injected into the extrusion molding block through the molding block guide pipe, which rapidly cools the extrusion molding block and accelerates the solidification process of the plastic solution.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-5 As shown, this utility model provides a technical solution: a mold for producing Bluetooth headset shells, including a fixed base 1, a headset shell production component 2 on the upper side of the fixed base 1, a sliding groove 201 on the inner side of the fixed base 1, a movable slider 202 installed on the inner side of the sliding groove 201, a casting tank 203 welded to the upper side of the movable slider 202, a tank guide pipe 204 installed on both the left and right ends of the inner side of the casting tank 203, a casting inner liner 205 in the middle of the tank guide pipe 204, a fixing slot 209 welded to the upper side of the casting tank 203, a top cover 210 installed on the upper side of the fixing slot 209, an extrusion shaping block 211 on the inner side of the casting inner liner 205, a glue injection port 212 on the upper side of the top cover 210, an exhaust port 213 on the opposite side of the glue injection port 212, and a shaping block guide pipe 214 on the inner side of the extrusion shaping block 211.

[0027] The upper cover 210 and the fixed slot 209 are connected by a slot, and the upper cover 210 and the fixed slot 209 fit tightly together. Each upper cover 210 and the fixed slot 209 corresponds to the other. When needed, simply insert the upper cover 210 into the fixed slot 209 to ensure a tight seal and prevent liquid leakage during the pouring process. This also facilitates quick opening and closing, improving production efficiency. The movable slider 202 and the slide 201 are connected by a slot, and the movable slider 202 fits tightly together with the slide 201. Four sets of movable sliders 202 are arranged. When needed, the corresponding pouring tank 203 is selected according to the required headphone shell size, and the movable slider 202 is fixed into the slide 201 within the fixed base 1. The fixed base 1 is then directly fixed to the production position.

[0028] In addition, a lifting film 206 is bonded to the lower inner end of the casting inner tube 205. An air rod 207 is connected to the lower side of the lifting film 206, and an air inlet pipe 208 is connected to the lower side of the air rod 207. The lifting film 206 is made of silicone rubber. The lifting film 206 forms a lifting structure through the air rod 207. After the casting is completed and solidified, gas is injected into the air rod 207 through the air inlet pipe 208. As the air rod 207 is lifted upward, the lifting film 206 will push out the earphone shell inside the casting inner tube 205, achieving rapid demolding.

[0029] like Figure 1-5As shown, the extrusion molding block 211 and the top cover 210 are welded together. A casting gap is left between the extrusion molding block 211 and the casting inner liner 205. The vent 213 and the injection port 212 are used for injection through the casting gap between the extrusion molding block 211 and the casting inner liner 205. When needed, the extrusion molding block 211 is inserted into the inside of the casting inner liner 205 through the top cover 210. At this time, the plastic solution is injected into the gap between the casting inner liner 205 and the extrusion molding block 211 through the injection port 212, and the air is discharged through the vent 213 to ensure that the plastic solution is evenly filled. After cooling and solidification, the extrusion molding block 211 is tightly bonded to the headphone shell, improving the molding accuracy and structural stability.

[0030] The shaping block guide pipes 214 are arranged in two groups, left and right, around the extrusion shaping blocks 211. The two groups of extrusion shaping blocks 211 are connected by pipes. The shaping block guide pipes 214 have a honeycomb structure. After the glue injection is completed, coolant is injected into the extrusion shaping blocks 211 through the shaping block guide pipes 214 to rapidly cool the extrusion shaping blocks 211 and accelerate the solidification process of the plastic solution. The tank guide pipe 204 is located between the casting tank 203 and the casting liner 205. The tank guide pipe 204 has a honeycomb structure. When needed, after the casting liner 205 in the casting tank 203 is poured, coolant can be poured into the honeycomb structure of the tank guide pipe 204, thereby reducing the surface temperature of the casting liner 205. This accelerates the solidification speed, makes the surface of the solidified earphone shell smoother and more delicate, and facilitates demolding.

[0031] Working principle: When needed, first fix the fixed base 1 to the required position, then select the corresponding casting tank 203 according to the earphone shell to be produced, and fix it in the slide groove 201 by moving the slider 202. Then, put the top cover 210 on the fixed slot 209, insert the extrusion shaping block 211 into the casting liner 205. After preparation, the molten plastic solution is injected into the gap between the extrusion shaping block 211 and the casting liner 205 through the injection port 212. As it is injected, air is discharged from the exhaust port 213. After the injection is completed, coolant is injected into the tank guide pipe 204 and the shaping block guide pipe 214 respectively to cool and shape the earphone shell. After the shaping is completed, the top cover 210 is opened, and then air is injected into the air rod 207 through the air inlet pipe 208. The air rod 207 lifts the lifting film 206, thereby pushing the earphone shell out from the casting liner 205. This completes the process of using a mold for producing Bluetooth earphone shells.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
