Microneedle machine shell plastic suction mold

The utility model relates to the technical field of plastic suction molds, in particular to a plastic suction mold for a microneedle machine shell. Comprising a mold base and a microneedle machine shell arranged in the mold base, a mold cavity is formed in the microneedle machine shell and comprises a convex cavity and a slope cavity, the slope cavity is located in the middle of the convex cavity, the opening end of the slope cavity is rectangular, and the slope cavity extends downwards, and a convex groove matched with the convex cavity is formed in the mold base; according to the utility model, the padding blocks are matched with the vent holes, so that effective exhaust can be realized; effective fixing of the fixing block is achieved through the positioning protrusion and the positioning groove; the four pressing plates are effectively positioned through the limiting protrusions and the limiting grooves, and the requirement for inward flanging of products is met. Through the design of the mold, the mass p
