The invention relates to a plastic mold facilitating product demolding. The plastic mold comprises a left mold base and a right mold base, the right mold base is arranged on a telescopic arm, a left mold plate is arranged on the right side of the left mold base, a right mold plate is arranged on the left side of the right mold base, a tensioning mechanism is arranged between the top end of the right mold plate and the top end of the right mold base, a mold cavity is formed between the left mold plate and the right mold plate, the mold cavity is used for forming a plastic product, the left moldplate comprises a main runner, a secondary runner, a gas ejection mechanism and an ejection mechanism, the main runner is horizontally arranged between the left mold base and the left mold plate, thesecondary runner is arranged in the left mold plate, the secondary runner adopts a C-shaped structure, the right end of the main runner communicates with the middle of the C-shaped structure, the mold cavity communicates with the two ends of the secondary runner, and the gas ejection mechanism is arranged in the left mold plate. According to the plastic mold facilitating product demolding, the ejection efficiency of a plastic product is high, and the ejection operation time is shortened; and the ejection quality is good, the production quality of the plastic product is improved, and the appearance quality of an assembled product is further improved.
