A groove is formed between the glue injection part and the extended support part.

[0009] Preferably, the boss is in a strip shape, and the glue inlet is communicated with the glue inlet channel.

[0010] Preferably, the ejector pin movably penetrates the glue inlet channel from the bottom of the glue inlet portion, the size of the boss matches the groove, and the boss is located in the groove.

[0011] (III) Beneficial effects

[0012] An extended support portion is provided at the side end of the glue inlet portion, so that all the blocks are located on the glue inlet flow channel. The sprue is not easy to fall off after mold opening, and is not easy to fly off after ejection, thereby effectively avoiding the risk of mold pressing after the sprue flies around. A boss is fixedly installed on the top of the ejector pin, and the boss is inserted into the groove. The boss is used to hold the block so that the block can stop steadily after being ejected and will not fly off. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The embodiment of the present application provides a side-glue injection mold structure for a mobile phone cover slide, which effectively solves the problem that half of the existing glue injection channel block remains on the slide and the other half is suspended, the nozzle is easy to fall off after mold opening, and it is very easy to fly off after ejection, resulting in the risk of mold compression due to nozzle flying out. The side-glue injection mold structure for a mobile phone cover slide is provided with an extended support portion at the side end of the glue injection portion, so that all the blocks are located on the glue injection channel, the nozzle is not easy to fall off after mold opening, and it is not easy to fly off after ejection, thereby effectively avoiding the risk of mold compression due to nozzle flying out, and a boss is fixedly installed at the top of the ejector pin, the boss is inserted into the groove, and the boss is used to support the block so that the block can stop steadily after ejection without flying out.

[0019] Embodiment: Figure 1 , Figure 2 and Figure 3 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that half of the existing glue inlet flow channel block is left on the slide and the other half is suspended, the nozzle is easy to fall off after mold opening, and it is very easy to fly after ejection, resulting in the risk of nozzle flying and mold pressing. The overall idea is as follows:

[0020] In view of the problems existing in the prior art, the utility model provides a side-glue injection mold structure for a mobile phone shell, comprising a glue injection part 1 and an ejector pin 4, a glue injection port 11 is provided on the side surface of the glue injection part 1, an extended support part 2 is fixedly installed on the side end of the glue injection part 1, a glue injection flow channel 3 is provided on the upper surface of the glue injection part 1, a stopper 41 is fixedly installed on the top of the ejector pin 4, the stopper 41 is located in the glue injection flow channel 3, a boss 5 is fixedly installed on the top of the ejector pin 4, a groove 12 is formed between the glue injection part 1 and the extended support part 2, the boss 5 is in a strip shape, the glue injection port 11 is communicated with the glue injection flow channel 3, and the ejector pin 4 is fixedly installed with a boss 5. The needle 4 movably penetrates the glue inlet flow channel 3 from the bottom of the glue inlet part 1. The size of the boss 5 is adapted to the groove 12. The boss 5 is located in the groove 12. An extended support part 2 is provided at the side end of the glue inlet part 1, so that the block 41 is completely located on the glue inlet flow channel 3.
