Mold ejection mechanism and injection mold

The utility model provides a mold ejection mechanism and an injection mold. The mold ejection mechanism comprises a mold core insert and an ejection block. An air inlet channel is arranged in the mold core insert; and the ejection block is arranged at the top of the air inlet channel and abuts against a product, so that high-pressure air drives the ejection block through the air inlet channel to separate the product from the mold core insert. According to the mold ejection mechanism, the ejection block is additionally arranged at the air inlet channel of the mold core insert, ejection is achieved by driving the ejection block through high-pressure air, movement of a mold core and an oil cylinder core pulling mechanism are omitted, the mold structure is simpler, and meanwhile the requirement for large inward bending of a product structure is met. 本实用新型提供了一种模具顶出机构和注塑模具。该模具顶出机构包括型芯镶件和顶出块。所述型芯镶件内设置有进气通道；所述顶出块设置于所述进气通道的顶部且与产品抵接，以使高压气体通过所述进气通道驱动所述顶出块将所述产品与所述型芯镶件分离。该模具顶出机构在型芯镶件的进气通道处增加顶出块，通过高压气体驱动顶出块实现顶出，没有型芯的运动和油缸抽
