Abstract
Description
Technical Field
[0001] This utility model relates to the field of headphone mold technology, and in particular to an integrated molding mold for producing ear hook headphones. Background Technology
[0002] In the production of ear-hook headphones, one-piece injection molding technology has become a key process for improving product structural integrity and production efficiency. Traditional production processes typically employ a modular injection molding and reassembly approach. For example, with behind-the-ear headphones, the ear hook and back hook sections need to be injection molded separately before being assembled with components like magnets. This process is not only cumbersome but also affects overall strength and aesthetics. Currently, in the one-piece molding process for ear hook structures, workers typically need to fix the semi-finished ear hook onto an insert, then insert the insert into a positioning groove in the lower mold for positioning and fixation. After the mold is closed, injection molding can begin. Afterward, workers need to manually pull the insert out of the positioning groove. Because the positioning groove has a certain depth, workers need to pull the insert out vertically upwards, which is difficult for workers and affects efficiency. Therefore, it is necessary to propose a new solution to address these problems. Utility Model Content
[0003] In view of the above, the present invention addresses the deficiencies of the prior art by providing an integrated molding mold for the production of ear-hook headphones, which solves the aforementioned problems.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] An integrated molding die for producing ear-hook headphones includes an upper mold plate, a lower mold plate, and an insert for auxiliary molding. The lower mold plate has a lower positioning groove on its opening and closing surface for inserting and positioning the lower part of the insert. The lower positioning groove limits the left and right sides of the insert and has a lower reserved space for the insert to move back and forth. The upper mold plate has an upper positioning groove on its opening and closing surface that corresponds to the upper part of the insert. The upper positioning groove limits the front, back, left, and right sides of the insert.
[0006] As a preferred embodiment, the top face of the insert has an inclined surface, and the upper mold plate has a pushing part. When the mold is closed, the pushing part abuts against the inclined surface, thereby applying a rearward pushing force to the insert and fixing the insert.
[0007] As a preferred embodiment, a pusher is fixed in the upper positioning groove of the upper template by screws, and the pusher has the aforementioned pusher portion.
[0008] As a preferred embodiment, the front side of the upper positioning groove is a low side, and the pushing part is higher than the rear side of the upper positioning groove.
[0009] As a preferred embodiment, the insert has a protrusion extending from its rear side. Correspondingly, the lower template has a lower groove, the upper template has an upper groove, and the upper and lower parts of the protrusion are respectively confined within the upper and lower grooves. The protrusion has a working part for assisting in forming.
[0010] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, its main features are:
[0011] By combining the left and right limiting and front and back movable design of the lower positioning groove with the all-round constraint of the upper positioning groove, a "dynamic positioning mechanism" is formed. Specifically, the lower positioning groove provides basic positioning for the insert, retains space for front and back movement, and avoids the disassembly difficulties caused by traditional tight fits; the upper positioning groove provides circumferential constraints in the front, back, left and right directions when the mold is closed, ensuring that the position of the insert is fixed during the molding process; after the mold is opened, because the insert is less restricted in the front and back direction, the operator can apply force in the front and back direction to directly remove the insert, which is very simple and quick.
[0012] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.
[0023] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.
[0024] Please see Figures 1 to 7 This utility model provides an integrated molding die for producing ear-hook headphones, including an upper template 10, a lower template 20, and an insert 30 for auxiliary molding. The lower template 20 has a lower positioning groove 21 on its opening and closing surface for insert 30 to be inserted and for positioning the lower part of insert 30. The lower positioning groove 21 limits the left and right sides of insert 30 and has a lower reserved space 22 for insert 30 to move back and forth. The upper template 10 has an upper positioning groove 11 on its opening and closing surface corresponding to the upper part of insert 30. The upper positioning groove 11 limits the front, back, left and right sides of insert 30.
[0025] By using the left and right limiting and front and back movable design of the lower positioning groove 21, combined with the all-round constraint of the upper positioning groove 11, a "dynamic positioning mechanism" is formed. Specifically, the lower positioning groove 21 provides basic positioning for the insert 30, retains front and back movement space, and avoids the disassembly difficulties caused by traditional tight fit; the upper positioning groove 11 provides circumferential constraints in the front, back, left and right directions when the mold is closed, ensuring that the position of the insert 30 is fixed during the molding process; when the mold is opened, since the insert 30 is less restricted in the front and back direction, the operator can apply force in the front and back direction to directly remove the insert 30, which is very simple and quick.
[0026] Furthermore, the top face of the insert 30 has an inclined surface 31, and the upper mold plate 10 has a pushing part 12. When the mold is closed, the pushing part 12 abuts against the inclined surface 31, thereby applying a rearward pushing force to the insert 30 and fixing the insert 30.
[0027] Furthermore, a pusher 13 is fixed in the upper positioning groove 11 of the upper template 10 by screws. The pusher 13 has the aforementioned pusher portion 12. The pusher 13 is fixed to the upper template 10 by screws. When the inclined surface 31 is worn or the angle needs to be adjusted, only the pusher 13 needs to be replaced instead of the entire upper template, thus reducing maintenance costs.
[0028] Furthermore, the front side of the upper positioning groove 11 is a low surface 111, and the pushing part 12 is higher than the rear side of the upper positioning groove 11. The low surface 111 is designed to facilitate mold opening while ensuring the fixing effect.
[0029] Furthermore, a protrusion 32 extends from the rear side of the insert 30. Correspondingly, the lower template 20 has a lower groove 23, and the upper template 10 has an upper groove 14. The upper and lower parts of the protrusion 32 are respectively confined within the upper groove 14 and the lower groove 23. The protrusion 32 has a working part 321 for auxiliary forming. The cooperative design of the protrusion 32 and the groove can further ensure the stability of the insert 30. In practice, the ear loop is connected to the working part 321 and thus positioned on the insert 30.
[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
