[0001] This utility model relates to the field of shell injection molding technology, and more specifically, to a wireless earphone shell injection molding device. Background Technology

[0002] The injection molding machine for wireless earphone shells is a specialized piece of equipment used to manufacture wireless earphone shells. It plays a crucial role in the production of wireless earphones, primarily by enabling efficient mass production. The injection molding machine can quickly produce a large number of wireless earphone shells, greatly improving production efficiency and meeting the large-scale market demand for wireless earphones.

[0003] During the injection molding process of wireless earphone shells, molten injection liquid needs to be poured into the mold, and the injection molding operation is completed by closing the upper and lower molds. However, it is difficult to adjust and switch the connection depth between the two shells according to actual use needs during the injection molding process, resulting in poor adjustability and applicability of injection molding. Summary of the Invention

[0005] Preferably, each of the multiple partition blocks is slidably connected to the injection-molded base shell, and the upper surface of the linkage plate is parallel to the lower surface of the partition blocks. The adjusting screw is rotatably connected to the support frame, and both the support frame and the adjusting screw are made of stainless steel. A support plate is fixedly connected to the lower surface of the injection-molded base shell, and a base plate is fixedly connected to the lower surface of the support plate, with the base plate fixedly connected to the support frame. An injection port is inserted into the outer wall of the injection-molded base shell, and the inner wall of the injection port is a smooth surface.

[0006] In use, this technology involves rotating an adjusting screw, which causes the sleeve block to move downwards under the force of the threaded transmission. Simultaneously, the sleeve block causes the linkage plate to move downwards, and the dividing block moves downwards between two adjacent molding grooves. This allows for adjustment of the connection depth between two adjacent molding grooves. The material is then injected through the injection port into multiple molding grooves inside the injection molding base shell, as well as into the gaps between two adjacent molding grooves.

[0007] Preferably, a pressure plate is provided above the injection-molded bottom shell, and a counterweight plate is fixedly connected to the top of the pressure plate; positioning blocks are fixedly connected to the lower surface of the counterweight plate near its four corners, and the positioning blocks are inserted into the injection-molded bottom shell; corner blocks are fixedly connected to the outer wall of the injection-molded bottom shell near its four corners, a guide strip is fixedly connected to the upper surface of each corner block, a support column is fixedly installed on the lower surface of the corner block, and a support ring is fixedly connected to the outer wall of the support column. The corner block has an L-shaped cross-section, and the cross-sectional area of ​​the upper surface of the guide strip is smaller than the area of ​​its lower surface.

[0008] When in use, this technology guides the counterweight plate into the corner block via a guide bar. The support ring supports the pillar, and the corner block supports the guide bar. The guide bar guides the counterweight plate to the corner position on the outer wall of the counterweight plate and moves it downward. The counterweight plate is guided along the inner wall of the guide bar into the inner wall of the corner block, which can firmly and stably limit the counterweight plate at multiple corner positions.

[0009] The technical effects and advantages of this utility model are as follows:

[0010] 1. This utility model adopts an interval adjustment component. The adjustment screw rotates inside the support frame. At the same time, the adjustment screw drives the sleeve block to move down under the action of the thread transmission force. The sleeve block drives the linkage plate to move down. The linkage plate drives multiple partition blocks to move down. The partition blocks move down between two adjacent molding grooves. The depth of the connection between two adjacent molding grooves can be adjusted to realize the adjustable gap depth between two adjacent molding grooves.

[0011] 2. This utility model uses a counterweight plate to drive the positioning block to be inserted into the edge position inside the injection molded bottom shell. The counterweight plate is inserted into the outer wall of the guide strip and guided into the corner block through the guide strip. The support column supports the corner block, the corner block supports the guide strip, and the counterweight plate is guided along the inner wall of the guide strip to the inner wall of the corner block, which greatly improves the stability of the injection molded bottom shell and the counterweight plate in multi-corner positions.

Detailed Implementation

[0018] 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.

[0019] As shown in Figures 1-5, a wireless earphone shell injection molding device is provided with an interval adjustment component. The interval adjustment component allows the depth of the connection between two adjacent molding grooves 2 to be adjusted, realizing adjustable injection molding of the gap depth between the two adjacent molding grooves 2. The specific structure of the interval adjustment component is as follows.

[0020] In this embodiment, as shown in Figures 1-4, the injection-molded base shell 1 is internally equipped with an interval adjustment assembly. The interval adjustment assembly includes multiple molding grooves 2, multiple dividing blocks 3, a linkage plate 4, a connecting block 5, an adjusting screw 6, and a support frame 7. The multiple molding grooves 2 are all located at the bottom of the inner wall of the injection-molded base shell 1. Each dividing block 3 is located between two adjacent molding grooves 2.

The adjusting screw 6 is rotatably connected to the support frame 7, and both the support frame 7 and the adjusting screw 6 are made of stainless steel.

[0021] In this embodiment, as shown in Figures 1-3, a support plate 8 is fixedly connected to the lower surface of the injection-molded bottom shell 1, and a base plate 9 is fixedly connected to the lower surface of the support plate 8. The base plate 9 is fixedly connected to the support frame 7 so that the base plate 9 supports the support plate 8, and the support plate 8 supports the injection-molded bottom shell 1, thereby increasing the stability of the injection-molded bottom shell 1. An injection port 10 is inserted and connected to the outer wall of the injection-molded bottom shell 1. The inner wall of the injection port 10 is a smooth surface so that the injection pipe can be connected to the injection port 10 to achieve docking and injection into the injection port, resulting in a better injection effect.

[0022] In use, this technology involves connecting an injection pipe to the injection port 10. Rotating the adjusting screw 6 within the support frame 7 causes the connecting block 5 to move downwards under the force transmitted through the thread. The connecting block 5 moves downwards along the inner wall of the support frame 7, simultaneously causing the linkage plate 4 to move downwards. The linkage plate 4 then moves multiple dividing blocks 3 downwards, positioning them between adjacent molding grooves 2. This allows for adjustment of the connection depth between adjacent molding grooves 2. After adjustment, stop rotating the adjusting screw 6, and then move the counterweight plate 13 downward. The counterweight plate 13 drives the pressure plate 11 to be inserted into the hole inside the injection molding base shell 1.

The cross-sectional shape of the corner block 14 is L-shaped, and the cross-sectional area of ​​the upper surface of the guide strip 15 is smaller than the area of ​​its lower surface.

[0024] In use, the counterweight plate 13 simultaneously drives the positioning block 12 to insert into the edge position inside the injection-molded bottom shell 1, and the counterweight plate 13 is inserted into the outer wall of the guide strip 15. It is guided into the corner block 14 by the guide strip 15.
