The invention provides a rear-mold reverse inclined-top pushing-out mechanism. Core-pulling of a product with an inclined hole in a demolding direction is guaranteed, and the mechanism is simple in structure, and easy to produce and assemble. The mechanism comprises a front mold core, a rear mold core, a pushing plate and a supporting plate, wherein a cavity is defined by a front mold core and a rear mold core, the rear mold core supports the pushing plate, and the inclined top penetrates through the pushing plate in an inclined mode and is installed in an inclined hole of a product of the cavity in a pushing mode. The mechanism is characterized in that a linear sliding groove is arranged at the bottom of the inclined top, the linear sliding groove is clamped in a linear rail of a linear guide sliding block, the linear guide sliding block supports a face needle plate, the linear guide sliding block is located in an inner installation cavity of the supporting plate, and the bottom of the inclined top is located in the inner installation cavity of the supporting plate.
Description
technical field [0001] The invention relates to the technical field of mold structures, in particular to a reverse inclined ejection mechanism for a rear mold. Background technique [0002] When designing injection molds, you will encounter some products that need to use some demoulding mechanisms before they can be released from the mold. For products with an oblique hole in the mold ejection direction, the oblique core-pulling mechanism adopted in the existing structure has a complex structure and troublesome manufacture and assembly. Contents of the invention [0003] In view of the above problems, the present invention provides a rear mold reverse inclined ejection mechanism, which ensures the core-pulling of products with inclined holes in the mold ejection direction, and at the same time has a simple structure, simple manufacture and assembly. [0004] The technical scheme of the ejection mechanism of the rear mold is as follows: it includes a front mold core, a...
