[0001] This utility model relates to the field of molds, specifically to a mold with a centrally located, precisely injection-molded speaker handle assembly. Background Technology

[0002] A mold is a type of mold and tool used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. It is used to create shaped items. A speaker handle refers to a handle designed for easy handling and installation on various audio equipment.

[0003] The existing molds have the following defects:

[0004] Before the speaker handle inside the mold can be cooled, it needs to be cooled manually, which is dangerous. The speaker handle cannot be cooled quickly during molding, so the molding cycle cannot be shortened.

[0005] The purpose of this invention is to design a mold with a precisely centered speaker handle to address the problems existing in the prior art. Utility Model Content

[0006] In view of the problems existing in the prior art, the present invention provides a mold with a precision injection molding component for a centrally located speaker handle, which can effectively solve at least one of the problems existing in the prior art.

[0007] The technical solution of this utility model is:

[0008] A mold for a precision injection-molded component with a centered speaker handle, comprising:

[0009] An upper mold base is provided with an upper template on its bottom end face, a lower template is provided below the upper template, a lower mold base is provided outside the lower template, a molding cavity is provided between the upper template and the lower template, and a centrally located precision injection molding component is provided between the upper mold base, the upper template, and the molding cavity;

[0010] A cooling box is provided inside the bottom end face of the lower mold base. Interfaces are provided inside the bottom end face of the upper mold base and on the left and right sides of the cooling box. An upper cooling channel is provided inside the upper mold plate. A transition channel connecting the upper cooling channel and the interface is provided on the upper mold base. A lower cooling channel is provided inside the lower mold plate.

[0011] A receiving groove is provided on the top surface of the lower mold base and below the interface. A connector is provided in the receiving groove for rotation and lifting. A flexible hose is connected to the bottom end of the connector. A driving communication device is provided between the connector, the flexible hose, and the lower mold base and within the receiving groove. The flexible hose on the left side is connected to the cooling tank through a liquid delivery device. The flexible hose on the right side is connected to the inlet of the lower cooling channel through a connecting pipe. The outlet of the lower cooling channel is connected to the cooling tank through a connecting channel.

[0012] Furthermore, the drive communication device includes a lifting platform, which is lifted and disposed within the receiving groove and located below the connector. The bottom end of the connector is rotatably connected to the lifting platform. The lifting platform is provided with a connection channel connecting the connector and the hose. The lifting platform is connected to the lower mold base through several telescopic components. A driven gear is provided outside the connector and above the lifting platform. The driven gear meshes with a driving gear. A rotating motor is provided between the lifting platform and the driving gear.

[0013] Furthermore, the infusion device includes an infusion tube, one end of which is connected to the bottom surface of the cooling tank, and the other end of which passes through the lower mold base and is connected to a flexible tube on the left side. A pump is provided between the infusion tube and the lower mold base, and a first solenoid valve is provided on the infusion tube and to the right of the pump.

[0014] Furthermore, the centering precision injection molding component includes a centering gating nozzle disposed on the upper mold base; and a precision injection channel disposed on the upper mold plate and connecting the centering gating nozzle and the molding cavity.

[0015] Furthermore, a replacement pipe with a valve is connected to the bottom end face of the cooling box.

[0016] Furthermore, a one-way valve is provided between the interface on the left and the transition channel on the left, and a second solenoid valve is provided between the interface on the right and the transition channel on the right.

[0017] Therefore, the present invention provides the following effects and / or advantages:

[0018] 1) The upper mold base and the lower mold base approach each other until they fit together. When the upper mold base and the lower mold base fit together, the upper mold plate and the lower mold plate form a molding cavity. When the upper mold base and the lower mold base fit together, the drive connecting device drives the joint and the interface to connect. The center precision injection molding component injects the injection melt into the molding cavity when the upper mold plate and the lower mold plate fit together. Then the liquid delivery device delivers the coolant in the cooling tank to the upper cooling channel and the lower cooling channel, thereby absorbing the heat of the speaker handle in the molding cavity. The setting of the drive connecting device allows the joint and the interface to connect or disconnect.

[0019] In summary: cooling of the speaker handle inside the mold can be achieved without manual operation, eliminating the dangers associated with manual operation; rapid cooling is possible during the molding of the speaker handle, thereby shortening the molding cycle.

[0020] 2) Before the upper mold base and the lower mold base are separated, the cooperation of the one-way valve and the second solenoid valve can prevent the coolant in the transition channel and the upper cooling channel from flowing out of the upper mold base and falling into the lower mold base after the upper mold base and the lower mold base are separated, thus preventing the lower mold base from being contaminated and reducing the waste of coolant.

[0021] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention are realized and obtained through the structures particularly pointed out in the description and the drawings.
