Problems solved by technology
[0003] In order to solve the problem that the corner nozzle is used in the prior art for button mold forming, the processing of the corner nozzle insert is cumbersome, and the working hours are long. At the same time, the mold core needs wire-cut insert holes, which further lengthens the working time and causes the strength of the mold core to deteriorate.

The invention discloses an improved structure of a nozzle for a key cap, which includes a ejector pin and a ejector plate, and a ejector pin is arranged on the mold ejector plate, and the ejector pin is used for ejecting a product in a mold core, and is characterized in that it also includes a nozzle needle, an inlet needle, and an ejector pin. Glue pipe and branch pipe, the glue inlet pipe is connected to one end of each branch pipe, the other end of each branch pipe is connected to the glue inlet, the glue inlet is connected to the side of the mold core, and the nozzle needle passes through the ejector plate to withstand the glue inlet pipe , a gap is provided in the ejector plate, and a bump is arranged on the part of the nozzle needle located in the gap of the ejector plate, and a gap is left between the gap of the ejector plate and the bump of the nozzle needle. The present invention solves the problem that in the prior art, the horn nozzle is used in the molding of button molds, the inserts of the horn nozzle are processed cumbersomely, and the working hours are long. At the same time, the mold core needs wire-cut insert holes, the working hours are further elongated, and the strength of the mold core is deteriorated. , providing an improved structure of the key cap nozzle which improves the strength of the mold core and saves a lot of man-hours for processing.
Description
technical field [0001] The invention relates to the technical field of molds, in particular to an improved structure of a key cap nozzle. Background technique [0002] At present, molds are widely used in production and people's daily life. Whether the structure of the mold is reasonable or not directly affects the quality of the product. At present, the corner nozzle is commonly used in button mold forming, and the corner nozzle is set at the lower part of the mold core for glue feeding, so that the product nozzle will not be higher. However, the processing of the corner nozzle inserts is cumbersome, and the working hours are long, especially if there are multiple holes in a mold, it is more time-consuming and laborious; Cap products generally have more inclined tops. Contents of the invention [0003] In order to solve the problem that the horn nozzle is used in the prior art for forming button molds, the inserts of the horn nozzle are cumbersome to process, and the wo...
