Detailed Description
To further illustrate the various embodiments, the present invention provides the accompanying drawings. The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the embodiments. With these references, one of ordinary skill in the art will appreciate other possible embodiments and advantages of the present invention. Elements in the figures are not drawn to scale and like reference numerals are generally used to indicate like elements.
The present invention will now be further described with reference to the accompanying drawings and detailed description.
Referring to fig. 2, as a preferred embodiment of the present invention, there is provided a four-point needle valve hot runner injection molding system for molding a mobile phone housing, comprising four vertically disposed needle valve hot runners 11, 12, 13, 14, each of which includes a hot nozzle valve port at the bottom thereof, for example, the needle valve hot runner 14 includes a hot nozzle valve port 140 at the bottom thereof. Each needle valve hot runner can independently control the needle valve to act through an electric control system, and further control whether a hot nozzle valve port is opened or not, so that in practical application, the four needle valve hot runners 11, 12, 13 and 14 can independently control the glue discharging time. In this embodiment, four needle valve hot runners 11, 12, 13, 14 are arranged at four corners to be respectively arranged at four edges of a rectangular mobile phone housing forming cavity correspondingly, so-called rectangular mobile phone housing forming cavity can be formed by closing a forming mold, and the four-point needle valve hot runner injection molding system of this embodiment is fixedly installed on the forming mold. The four-point needle valve hot runner injection molding system further comprises four glue injection cold runners 21, 22, 23 and 24 which are correspondingly arranged on the periphery of four sides of the rectangular mobile phone shell molding cavity respectively, each glue injection cold runner is connected with a corresponding hot nozzle valve port, each glue injection cold runner is provided with a glue outlet nozzle which horizontally extends and injects glue towards one side of the rectangular mobile phone shell molding cavity, and for example, the glue injection cold runner 24 is provided with a glue outlet nozzle 240.
This embodiment is through setting up as above, and a needle valve hot runner corresponds the side that sets up at rectangle cell-phone casing shaping die cavity to carry out the injecting glue through an injecting glue cold runner alone, can shorten the finished piece cycle of forming, improved injection moulding efficiency by a wide margin.
