[0018] As a further improvement to the above solution, a drive motor is fixedly installed on the top of the stabilizing plate, and a drive gear is fixedly connected to the output end of the drive motor, and the drive gear meshes with the force-bearing gear.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention uses an electric push rod to lower the lower mold under the limit of the limiting rod. At this time, the top platen can eject the product, completing the ejection operation. Driven by the drive motor, the drive gear rotates clockwise, which can rotate the force gear counterclockwise. The mounting plate pulls the clamping rod to slide inside the lower mold, which drives the connecting rod to move closer to the center of the support rod. This ensures that multiple sets of clamping rods are close together inside the lower mold, thereby clamping the product in the forming groove. This ensures that the product is fixed by the clamping components and will not fall to the ground due to the action of the ejection mold. This greatly improves the stability of the product during the demolding process and reduces the scrap rate caused by the product falling. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] Example:

[0030] Please combine Figures 1-5 This embodiment provides a mold for producing Bluetooth earphone shells, including a top mold assembly 1. The top mold assembly 1 includes a stabilizing plate 101, a limiting rod 102 fixedly mounted on the top of the stabilizing plate 101, an upper mold 103 fixedly mounted on the outer surface of the limiting rod 102, an inlet 104 opened on the top of the upper mold 103, and a limiting plate 105 fixedly mounted on the bottom of the upper mold 103. It also includes:

[0031] Bottom mold assembly 2 includes an electric push rod 201, a lower mold 204 is provided on the top of the electric push rod 201, and a forming groove 205 is provided inside the lower mold 204;

[0032] The clamping assembly 3 includes a support rod 301, a connecting rod 306 is provided on the top of the support rod 301, and a clamping rod 307 is fixedly installed on the top of the connecting rod 306.

[0033] An electric push rod 201 is fixedly installed on the top of the stabilizing plate 101, and a mounting base 202 is fixedly installed on the top of the electric push rod 201.

[0034] A connecting seat 203 is fixedly installed on the outer surface of the mounting base 202. A lower mold 204 is fixedly installed on one side of the connecting seat 203. A clamping rod 307 is slidably installed inside the lower mold 204.

[0035] The bottom mold assembly 2 is lowered by the electric push rod 201. Since the lower mold 204 is connected to the mounting base 202 by the connecting seat 203, when the electric push rod 201 lowers the mounting base 202, it will drive the lower mold 204 to lower under the limit of the limit rod 102.

[0036] A support rod 301 is fixedly installed at the center of the top of the stabilizing plate 101, and a top template 302 is fixedly installed on the top of the support rod 301.

[0037] The dimensions of the top template 302 match the dimensions of the forming groove 205, and the limiting plate 105 is sleeved on the outer surface of the top template 302.

[0038] Since the limiting plate 105 is sleeved on the surface of the top template 302 and the limiting plate 105 is located on the inner wall of the forming groove 205, it can be ensured that the upper mold 103 and the lower mold 204 will not leak due to gaps during forming.

[0039] A force-bearing gear 303 is rotatably mounted on the outer surface of the support rod 301, and a mounting plate 304 is fixedly mounted on the top of the force-bearing gear 303.

[0040] Multiple sets of mounting rods 305 are fixedly installed on the top of the mounting plate 304, and connecting rods 306 are sleeved on the outer surface of the mounting rods 305.

[0041] A drive motor 308 is fixedly installed on the top of the stabilizing plate 101. A drive gear 309 is fixedly connected to the output end of the drive motor 308. The drive gear 309 meshes with the force-bearing gear 303.

[0042] Driven by the drive motor 308, the drive gear 309 rotates clockwise, which in turn rotates the force-bearing gear 303 counterclockwise.

[0043] The implementation principle of a mold for producing Bluetooth earphone shells in this application embodiment is as follows: molten plastic is injected into the molding groove 205 through the inlet 104. Since the limiting plate 105 is sleeved on the surface of the top template 302 and the limiting plate 105 is set in the inner wall of the molding groove 205, it can ensure that the upper mold 103 and the lower mold 204 will not leak due to gaps during molding. The stabilizing plate 101 set in the top mold assembly 1 can support the bottom mold assembly 2 and the clamping assembly 3. At the same time, the limiting rod 102 can support the inlet 104 to ensure the stability of injection molding.

[0044] The bottom mold assembly 2 is lowered by the electric push rod 201. Since the lower mold 204 is connected to the mounting base 202 by the connecting seat 203, when the electric push rod 201 lowers the mounting base 202, it will drive the lower mold 204 to lower under the limit of the limit rod 102. At this time, since the support rod 301 is fixedly installed on the top of the stabilizing plate 101, the product can be ejected by the top template 302 to complete the top mold operation. The drive motor 308 drives the drive gear 309 to rotate clockwise, which can rotate the force gear 303 counterclockwise.

[0045] Since the clamping rod 307 is rotatably mounted on the outer surface of the mounting rod 305 via the connecting rod 306, when the force-bearing gear 303 rotates, the mounting plate 304 will pull the clamping rod 307 to slide within the lower mold 204. As the force-bearing gear 303 is rotating counterclockwise at this time, it will drive the connecting rod 306 to move closer to the center of the support rod 301, ensuring that multiple sets of clamping rods 307 move closer within the lower mold 204, thereby clamping the product in the molding groove 205. This ensures that the product is fixed by the clamping assembly 3 and will not fall to the ground due to the movement of the top mold. This greatly improves the stability of the product during the demolding process and reduces the scrap rate caused by the product falling.

[0046] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
