The invention discloses a delivery spray jig for robot extrusion casting. The delivery spray jig comprises a connection seat, a pneumatic clamping jaw and a multi-head spray module, wherein the pneumatic clamping jaw and the multi-head spray module are arranged on the connection seat. The delivery spray jig is ingenious in structural design, and the pneumatic clamping jaw and the multi-head spray module are reasonably arranged, so that spray action can be carried out immediately after realizing a deliver function, the delivery and spray actions can be completely rapidly, the whole completion action is continuous and smooth, the working efficiency is effectively improved and the working stability is good; the multi-head spray module adopts a multi-head structure, so that the liquid spray is refined and uniform, the adhesion effect of a parting agent on modular surfaces is improved, the spray effect is good, the using of the parting agent is decreased, the production cost is reduced and the factory production is more energy-saving and environment-friendly; moreover, the delivery spray jig is simple and compact in whole structure, small in volume and easy to mount and maintain in daily life, can be adapted to multi-axis robots to realize high flexibility, can be used for realizing multi-dimensional multi-angle delivery spray action, and is wide in application range and beneficial for wide popularization and application.
