摘要：分析了外螺紋噴水槍座的結構，塑件上的外螺紋采用滑塊成型，4個小孔采用鑲件成型，塑件內表面的扣位采用斜推結構成型，模具采用1模2腔結構，成型的塑件由斜推結構推出。經生產實踐證明，模具結構合理，生產效率高，成型的塑件脫模順利，可為同類塑件的成型提供參考。

Design of injection mould for water gun base with external thread
HUANG Zhi (Zhongshan Polytechnic, Zhongshan, Guangdong 528400, China)
Abstract: The structure of water gun base with external thread was analyzed, the outer thread of the product was moulded by using slider, and the 4 holes were moulded by insert parts, and the buckles in the inner surface of product were moulded by inclined block. It designed two cavities in the mould, and the plastics were pushed through the inclined ejection mechanism. The production practice has proved that the mould structure was reasonable, and the plastics were ejected smoothly, which could provide reference for similar parts.
Key words: water gun base with external thread; injection mould; inclined ejection components; slider; pin-point gate
