Detailed ways

In order to further illustrate each embodiment, the present invention provides accompanying drawings, which are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments, and can be used to explain the operation principles of the embodiments in conjunction with the relevant descriptions in the specification, With reference to these contents, those of ordinary skill in the art will understand other possible implementations and advantages of the present invention. Components in the figures are not drawn to scale, and similar component symbols are generally used to denote similar components.

According to an embodiment of the present invention, a molding die for buttons of an earphone control box is provided.

Example 1:

As shown in Figures 1-2, according to an embodiment of the present invention, the molding die for the buttons of the earphone control box includes a fixed template 1. The bottom end of the fixed template 1 is provided with a backing plate 2 matched with it. The backing plate The bottom end of the 2 is provided with a movable template 3, the fixed template 1 and the movable template 3 are provided with a runner 4, and the middle position of the movable template 3 is provided with a molding matched with the runner 4. Hole 5, the interior of the movable template 3 is provided with a number of mold cavities 6 that are all distributed, the bottom end of the movable template 3 is provided with a top plate 7 that matches with it, and the top of the top plate 7 is provided with a number of For the top block 8 matched with the mold cavity 6 , the bottom end of the top plate 7 is provided with a seat plate 9 matched with it, and the middle position of the seat plate 9 is provided with a top rod 10 matched with the top plate 7 .

The specific settings and functions of the fixed template 1, the positioning rod 11, the runner 4, the mold cavity 6, the backing plate 2 and the runner 14 will be described in detail below.

As shown in Figure 1, when the equipment is in use, after the equipment is clamped, the injection material starts to inject plastic into the equipment through the runner 4. At this time, the injection plastic fills the molding hole 5 and slowly enters the mold cavity 6 through the runner 14. , and cooperate with the top block 8 to form a key shape. During the mold clamping process, the positioning rod 11 can effectively assist the mold clamping positioning, and the cushion block 13 can also protect the equipment. After the mold is closed, the fixed template and the movable template 3 are separated. , the connecting device pushes the top plate 7 through the ejector rod 10 so that the ejector block pushes out the molding button, and then the remaining molding material in the flow channel 14 drives the remaining material inside the molding hole 5 to be ejected together to complete the entire process.

Embodiment 2:

As shown in FIG. 1-2 , both sides of the top of the top plate 7 are respectively provided with positioning rods 11 that cooperate with the movable template 3 , and a connecting sleeve 12 that cooperates with the fixed template 1 . , there are spacers 13 on both sides between the seat plate 9 and the fixed plate 1, respectively, and a flow channel 14 is arranged between the mold cavity 6 and the forming hole 5, and the runner 4 is The top is provided with a gate 15 matched with the fixed template 1, and a number of cooling water channels 16 are arranged inside the movable template 3. It is not difficult to see from the above design that the cooling water channels 16 can make the equipment run better. Avoid the injection molding temperature is too high and cannot be formed immediately, and control the molding temperature of the equipment.

In order to facilitate the understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in the actual process will be described in detail below.

In practical application, after the equipment is closed, the injection agent starts to inject plastic into the equipment through the runner 4. At this time, the injection plastic fills the molding hole 5 and slowly enters the mold cavity 6 through the runner 14, and cooperates with the top The block 8 forms a key shape. During the clamping process, the positioning rod 11 can effectively assist the clamping and positioning, and the cushion block 13 can also protect the equipment. After the clamping is formed, the fixed template and the movable template 3 are separated, and the connecting device The rod 10 pushes the top plate 7 so that the top block pushes out the forming button, and then the residual material in the forming hole 5 is driven out together by the residual forming material in the flow channel 14 to complete the whole process.

To sum up, with the help of the above technical solutions of the present invention, it is effectively ensured that the equipment can realize the formation of a plurality of control box buttons of the same model or different models, and the structure of the equipment is simple, which can effectively reduce the production cost, and also It is convenient for maintenance and replacement. At the same time, the movable mold can be quickly replaced, and the mold can be quickly removed after the mold is formed, thereby increasing the overall work efficiency and making the equipment more practical.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the within the protection scope of the present invention.
