Abstract

The invention provides an injection mold for processing a product with an oblique hole, and belongs to the technical field of molds. The injection mold comprises a fixed mold middle plate, a movable mold middle plate and a movable mold seat plate, wherein an injection molding cavity for forming a product with an oblique hole is formed by buckling the fixed mold middle plate and the movable mold middle plate; a pushing assembly is movably mounted between the movable mold middle plate and the movable mold seat plate; a straight ejection block connected with the pushing assembly is embedded into the movable mold middle plate; a mounting slot is formed in the straight ejection block, and an inclined core pulling needle is mounted in the mounting slot; a resetting piece sleeving the core pulling needle is also mounted in the mounting slot; during mold assembling, one end of the core pulling needle penetrates through the straight ejection block and is inserted into the oblique hole of the product, and the other end of the core pulling needle is pressed against the movable mold middle plate; during mold opening, the pushing assembly upwards ejects the product and simultaneously drives the straight ejection block to move upwards; at the moment, the resetting piece works and drives the core pulling needle to be separated from the oblique hole of the product. The injection mold has the advantages of simple structure, high working efficiency and convenience in maintenance.
