Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to an injection molding mold structure for sound network implantation. Background Art

[0002] During the production of injection molds, some products often need to implant foreign materials such as mesh, nylon, steel wire, etc. in order to improve strength and tensile strength. In some cases, the flexible material is combined with the plastic part through injection molding to fix the flexible material, such as the sound mesh of headphones. The traditional way of fixing the sound mesh is to apply glue to the plastic part and then stick the sound mesh on. However, in this structure fixed by glue, the glue can easily lose its viscosity or reduce its viscosity, causing the sound mesh to fall off, and the firmness of the glue itself is relatively low. Therefore, the method of implanting injection molding to fix the sound mesh came into being. The sound mesh implantation technology is to implant the sound mesh directly into the mold for injection molding, and fix the sound mesh with plastic, breaking the traditional mode of sticking the sound mesh with glue. The shape of the sound mesh on the plastic has increased from the initial vertical, parallel, and angle to the current number and more shapes, such as compound angles, various angles plus arc combinations to meet market demand; however, with the increase in demand, the sound mesh is prone to displacement or falling off in the mold cavity during the implantation injection molding process, which increases the difficulty of molding the finished sound mesh and reduces the molding quality of the sound mesh, which in turn leads to low yield.

DETAILED DESCRIPTION

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] like Figure 1-9 As shown, an injection molding mold structure for sound mesh implantation is used. By implanting the sound mesh into the injection molding mold, the plastic product and the sound mesh are combined, and the sound mesh is fixed by plastic. The injection molding mold includes a male mold structure 1 and a female mold structure 2. The male mold structure and the female mold structure 2 are matched to achieve injection molding.

[0026] The male mold structure 1 comprises a male mold pad 11, a male mold plate 12 and a male mold core 13. The male mold core 13 is provided with a male mold cavity 131. A male mold insert 15 is inserted into the male mold cavity 131. The male mold insert 15 is provided with a plurality of suction holes 151. A plurality of male mold springs 18 are provided between the male mold pad 11 and the male mold plate 12. The female mold structure 2 comprises a female mold pad 21, a female mold plate 22 and a female mold core 23. A female mold cavity 231 is provided on the female mold core 23. A plurality of female mold inserts 25 are inserted into the female mold cavity 231. The side of the female mold insert 25 close to the female mold pad 21 is abutted with a female mold insert pin 26. The female mold insert pin 26 is inserted into the female mold pad 21. A female mold spring 27 is sleeved on the female mold insert pin 26. The injection molding of the product is achieved by the mold combination of the male mold core 13 and the female mold core 23. The male mold structure 1 opens and closes the mold with the female mold structure 2 under the push of the injection molding machine. The male mold cavity 131 on the male mold core 13 and the female mold cavity 231 on the female mold core 23 form the injection cavity of the product, which is used for molding molten liquid plastic; the male mold insert 15 is used to fix the sound net, and air is sucked through the suction hole 15 to achieve adsorption and fixation of the sound net; the male mold spring 18 can apply an elastic force to the male mold plate 12, so that before the mold is closed, a groove can be formed between the male mold core 13 and the male mold insert 15, which is used to limit the sound net adsorbed by the male mold insert 15 to prevent the sound net from tilting and causing the net to deviate. The female mold insert 25 is used for the male mold structure 1 and the female mold structure 2 to first contact with the sound net adsorbed by the male mold insert 15 during the mold closing process, to ensure that the sound net is not skewed during the mold closing process, and to make the sound net attached to the male mold insert 15, to shape the sound net, and to ensure the quality of the sound net implantation; the female mold spring 27 is used to provide an elastic force to the female mold insert pin 26, and the female mold insert 25 is pushed by the female mold insert pin 26 to move and extend out of the female mold cavity 231 on the female mold core 23, so that the female mold insert 25 first contacts the sound net with the female mold core 23, and as the mold closing continues, the female mold spring 27 can be compressed, so that the female mold insert pin 26 and the female mold insert 25 can retreat, that is, the female mold insert 25 can retreat into the female mold core 23, and will not affect the implantation injection molding operation of the sound net.

[0027] In the present application, a male mold core pad 14 is provided on the side of the male mold core 13 close to the male mold pad 11, and the male mold core pad 14 is installed on the male mold plate 12. A male mold insert pad 16 is sleeved on the male mold insert 15, and the male mold insert pad 16 is installed on the male mold pad 11. The male mold pad 11 and the male mold plate 12 are connected with equal height screws 17. Among them, the male mold core pad 14 is used to fix the male mold core 13 on the male mold plate 12, and the side of the male mold plate 12 is provided with a mounting groove for the installation of the male mold core pad 14, and the male mold core pad 14 is fixed to the male mold plate 12 by screws; the male mold pad 11 is provided with a mounting groove for the installation of the male mold insert pad 16, and the male mold insert pad 16 is fixed by screws, and the male mold insert 15 passes through the male mold insert pad 16 to achieve the connection and fixation of the male mold insert 15 and the male mold pad 11. The male mold pad 11 is provided with a plurality of mounting holes for matching the male mold spring 18, which are used for limiting and mounting the male mold spring 18. In the present application, there are four male mold springs 18, which are arranged in a rectangular array at the four corners of the male mold pad 11 to ensure that the male mold spring 18 exerts a stable force on the male mold plate 12.

[0028] In the present application, a male mold cavity 131 is provided with a male mold core hole 132 that penetrates through the male mold core hole 132, and the male mold insert 15 is provided in the male mold core hole 132. The setting of the male mold core hole 132 facilitates the installation and movement of the male mold insert 15. Before the mold is closed, the male mold spring 18 applies an elastic force to the male mold plate 12, so that there is a gap between the male mold pad 11 and the male mold plate 12, and then the male mold insert 15 retreats a distance in the male mold core hole 132 of the male mold core 13, thereby forming a groove. When the sound net is implanted on the male mold insert 15, the sound net is in the groove, so that the sound net is limited by the groove to prevent the sound net from being skewed and causing the net to be biased. The end face of the male mold insert 15 is arc-shaped, which is used for the implantation and injection molding of the arc-shaped sound net; three suction holes 151 are evenly arranged on the male mold insert 15 to ensure that the sound net is firmly adsorbed.

[0029] In the present application, a mother mold core pad 24 is provided on the side of the mother mold core 23 close to the mother mold pad 21, and the mother mold core pad 24 is installed on the mother mold pad 21. The mother mold core pad 24 is used to limit the mother mold core 23, the mother mold insert 25 and the mother mold insert pin. The mother mold core pad 24 is fixed to the mother mold pad 21 by screws, and can limit the mother mold insert pin 26 to ensure that the mother mold insert pin 26 only moves within a set range. At the same time, the side of the mother mold core pad 24 away from the mother mold pad 21 abuts against the mother mold plate 22, and can limit the mother mold core 23 to ensure that the mother mold core 23 is firmly fixed; at the same time, the mother mold insert 25 is limited in the mother mold core hole 233 on the mother mold core 23, which does not hinder the movement of the mother mold insert 25, and at the same time, the position of the mother mold insert 25 is limited to ensure that the mother mold insert 25 can only move within a specific range.

[0030] In the present application, a circular step 261 is provided in the middle of the mother mold insert pin 26, and the mother mold spring 27 is provided between the circular step 261 and the mother mold pad 21. The end of the mother mold insert pin 26 away from the mother mold pad 21 passes through the mother mold core pad 24 and abuts against the mother mold insert 25. The provision of the circular step 261 ensures that the mother mold spring 27 can apply elastic force to the mother mold insert pin 26, ensuring that the mother mold insert pin 26 can move left and right, thereby ensuring that the mother mold insert 25 can move left and right.

[0031] In the present application, a profiling protrusion 232 is provided in the female mold cavity 231, and the profiling protrusion 232 matches the end face of the male mold insert 15. The profiling protrusion 232 is a protruding concave arc surface, which matches the arc-shaped protruding end face of the male mold insert 15. After the mold is closed, the sound net can be clamped between the profiling protrusion 232 and the end face of the male mold insert 15 to ensure the contact surface with the sound net, so that the sound net can be completely attached to the end face of the male mold insert 15, and the sound net is shaped to form an arc structure, which ensures the quality of the sound net implantation injection molding. The profiling protrusion 232 is provided with a female mold core hole 233, which is used for the female mold insert 25 to pass through, ensuring that the end face of the female mold insert 25 can pass through the female mold core 23.

[0032] In the present application, a female mold screw 28 is connected between the female mold pad 21 and the female mold plate 22 to realize the installation and fixation of the female mold plate 22. The sides of the male mold core 13, the male mold insert 15 and the female mold core 23 are all provided with limiting protrusions, which are used for limiting and positioning the male mold core 13, the male mold insert 15 and the female mold core 23 during installation, so as to facilitate the rapid installation of the male mold core 13, the male mold insert 15 and the female mold core 23.

[0033] In this application, the workflow of the injection molding mold structure is:

[0034] The sound net is implanted in the male mold structure: under the action of the male mold spring 18, there is a gap between the male mold plate 12 and the male mold pad 11, so that the male mold core 13 connected to the male mold plate 12 is relatively displaced relative to the male mold insert 15 connected to the male mold pad 11, that is, the male mold core hole 132 and the male mold insert 15 form a groove for limiting the sound net, and the sound net is placed in the groove through the external transport mechanism, and then the sound net is sucked and fixed in the groove and attached to the end face of the male mold insert 15 through the suction hole 151;

[0035] In-mold shaping and injection molding of the sound net: the female mold insert 25 of the female mold structure 2 extends out of the female mold core 23 for a certain distance under the action of the female mold spring 27 and the female mold insert pin 26, and the male mold structure 1 is gradually molded with the female mold structure 2 under the push of the injection molding machine. The end face of the female mold insert 25 first contacts the sound net, and then as the mold closing continues, the male mold plate 12 and the female mold plate 22 gradually approach each other, and the contoured protrusion 232 in the female model cavity 231 of the female mold core 23 contacts the sound net, and the sound net is completely pressed against the end face of the male mold insert 15 to achieve the shaping of the sound net. When the male mold plate 12 and the female mold plate 22 are completely fitted, the mold closing is completed, and liquid plastic is injected into the mold cavity formed by the male model cavity 131 and the female model cavity 231 through the injection molding machine to complete the implantation injection molding of the sound net.
