FIELD: process engineering.
SUBSTANCE: invention relates to injection or compression moulds with cooling channels. Injection or compression mould intended for moulding bottle performs comprises two parts of female die. Note here that each said part comprises recess formed by bottle perform neck shaping surface and channel appliance for cooling for coolant to flow there through. Note also that channel appliance defines coolant trajectory and comprises curved channel surrounding said recess, inlet channel provided with feed section running into curved channel provided with outlet section turning out of curved channel. Note that curved channel, inlet and outlet sections are arranged so that they are crossed by common plane including aforesaid trajectory.
EFFECT: higher cooling efficiency, simplified design.
