Description

Technical Field

[0001] The utility model relates to the technical field of flow control components, in particular to an injection molding flow control component for a mobile phone battery cover. Background Technique

[0002] The main functions of the mobile phone battery cover include fixing and sealing, current conduction, pressure relief, fuse protection and reducing electro-corrosion. The battery cover is laser welded with the aluminum shell to fix and seal the internal battery core, preventing safety accidents such as internal short circuit or explosion of the battery. The pole column and the adapter plate on the battery cover are welded with the battery core tab to ensure the conduction of the charging and discharging current of the battery core. However, when the existing mobile phone battery cover is injection molded, an injection molding device is used for assistance.

[0003] When the existing mobile phone battery cover is injection molded, an injection molding device is used for assistance. However, when the existing injection molding device is in use, it is unable to monitor the flow rate, which easily causes overflow due to too fast flow rate, resulting in waste of materials. Content of the Utility Model

[0004] The purpose of the utility model is to provide an injection molding flow control component for a mobile phone battery cover, so as to solve the problem that the existing injection molding device is unable to monitor the flow rate during use, which easily causes overflow due to too fast flow rate, resulting in waste of materials as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution, an injection molding flow control component for a mobile phone battery cover, including a diversion pipe:

[0006] One end outer wall of the diversion pipe is sleeved with a threaded sleeve, the inner surface of the threaded sleeve is connected with a fixing ring, one end of the fixing ring is connected with a support ring, one end surface of the support ring is connected with a support spring, one end of the support spring is connected with a pressure ball, and a sealing pad is arranged on one end surface of the pressure ball.

[0007] Preferably, the outer surface of one end of the diversion pipe is provided with threads, and the threaded sleeve is connected and fixed by using the threads arranged on the outer surface of the diversion pipe.

[0008] Preferably, the support ring and the pressure ball are elastically connected by a support spring, and the diameter of the sealing pad is the same as the inner diameter of the outlet of the diversion pipe.

[0009] Preferably, the pressure ball is inserted into the diversion pipe and is slidably connected with the diversion pipe. A plurality of groups of through holes are arranged on the surface of the pressure ball, and the through holes opened on the pressure ball are used for assisting in diversion.

[0010] Preferably, one end surface of the threaded sleeve is connected with a bearing, one end of the bearing is movably connected with a fixing screw sleeve, a rubber pad is arranged on the inner surface of the fixing screw sleeve, and a positioning rod is connected to one end of the fixing screw sleeve.

[0011] Preferably, one end of the positioning rod is inserted into the inside of the diversion pipe, and the fixed sleeve is used to dock with the feeding pipe.

[0012] Preferably, the threaded sleeve and the fixed sleeve are movably connected by a bearing, and the rubber pad is used for buffering between the fixed sleeve and the feeding pipe.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By inserting the pressure ball into the inside of the diversion pipe, then rotating the threaded sleeve to be connected to the outer wall of one end of the diversion pipe, and using the thread provided on the outer surface of the diversion pipe to limit the threaded sleeve, thereby supporting the support spring and the pressure ball connected to one end of the support ring through the fixing ring. When the injected liquid passes through the inside of the diversion pipe, the liquid pressure will support the movement of the pressure ball, causing the support spring to extend. When the liquid pressure is too high, the sealing pad provided at one end of the pressure ball moves towards the outlet of the diversion pipe, thereby reducing the outlet of the diversion pipe. After adjusting the flow rate subsequently, the support spring pulls the pressure ball to reset, thereby restoring the normal supply speed, avoiding the problem that existing equipment cannot monitor the flow rate, easily causing overflow due to too fast flow rate and resulting in material waste.

[0015] 2. When inserting the feeding pipe into the inside of the fixed sleeve, rotate the angle of the fixed sleeve to make it rotate on its own at one end of the bearing. Use the fixed sleeve to connect and fix the feeding pipe, and use the rubber pad to fill the gap between the fixed sleeve and the feeding pipe for buffering, making the two in flexible contact. Thus, the material is supplied into the inside of the fixed sleeve through the feeding pipe, and is guided to the inside of the threaded sleeve and the diversion pipe through the positioning rod for subsequent output.

[0027] Further, the support ring 4 and the pressure ball 6 are elastically connected by a support spring 5, and the diameter of the sealing gasket 7 is the same as the inner diameter of the outlet of the diversion pipe 1, so as to realize the filling and sealing of the outlet of the diversion pipe 1 by the sealing gasket 7.

[0028] Further, the pressure ball 6 is inserted into the diversion pipe 1 and is slidably connected with the diversion pipe 1. A plurality of groups of through holes are provided on the surface of the pressure ball 6, and the through holes provided on the pressure ball 6 are used to assist in diversion, so as to realize the guiding effect on the liquid through the through holes provided on the pressure ball 6.

[0029] Further, a bearing 8 is connected to one end surface of the threaded sleeve 2, a fixed screw sleeve 9 is movably connected to one end of the bearing 8, a rubber gasket 10 is arranged on the inner surface of the fixed screw sleeve 9, and a positioning rod 11 is connected to one end of the fixed screw sleeve 9, so as to realize the limitation of the feeding pipeline by adjusting the angle of the fixed screw sleeve 9.

[0030] Further, one end of the positioning rod 11 is inserted into the inside of the diversion pipe 1, and the fixed sleeve 9 is used to dock with the feeding pipe to realize the connection and fixation of the feeding pipe through the fixed sleeve 9.

[0032] Working principle: When controlling the flow during the injection molding of the mobile phone battery cover, the pressure ball 6 is inserted into the inside of the diversion pipe 1, and then the threaded sleeve 2 is rotatably connected to the outer wall of one end of the diversion pipe 1. The threaded sleeve 2 is limited by the thread provided on the outer surface of the diversion pipe 1, so as to support the support spring 5 and the pressure ball 6 connected to one end of the support ring 4 through the fixing ring 3. When the liquid for injection molding passes through the inside of the diversion pipe 1, the liquid pressure will support the pressure ball 6 to move, causing the support spring 5 to extend. When the liquid pressure is too high, the sealing pad 7 provided at one end of the pressure ball 6 moves towards the outlet of the diversion pipe 1, so that the outlet of the diversion pipe 1 becomes smaller. After adjusting the flow rate subsequently, the support spring 5 pulls the pressure ball 6 to reset, so as to restore the normal supply speed.

The feeding pipe is connected and fixed by the fixed sleeve 9, and the rubber pad 10 is used to fill the gap between the fixed sleeve 9 and the feeding pipe for buffering, so that the two are in flexible contact. Thus, the material is supplied into the inside of the fixed sleeve 9 through the feeding pipe and is guided to the inside of the threaded sleeve 2 and the diversion pipe 1 by the positioning rod 11 for subsequent output.
