Embodiment

[0023] refer to Figure 1-3 As shown, this embodiment is a secondary ejection mold structure for anti-sticking products, including the lower mold core 11 embedded in the lower template 1, the ejector plate 12 arranged under the lower template 1, and the ejector plate 12 at the bottom of the ejector plate 12. Bottom plate 13, a number of thimbles 2 and a number of tubes 3 arranged on the ejector plate 12 and extending to the surface through the lower mold core 11, inclined rods 4 arranged on the ejector plate 12 and extending to the surface of the lower mold core 11, set on the bottom plate 13 and runs through the inner needle 31 of the cylinder 3; when the mold is opened, the product in the lower mold core 11 is absorbed by the manipulator (not shown in the figure), and the inner needle 31, thimble 2 and inclined rod 4 are pre-balanced to eject the product. The cylinder 3 is lifted higher than the surface of the inner needle 31 to eject the product twice, and the surface of th...

Abstract

The invention discloses a die structure for secondary ejection of an anti-sticking product. The die structure comprises a lower die core embedded in a lower die plate, a thimble plate arranged below the lower die plate, a bottom plate arranged at the bottom of the thimble plate, a plurality of thimbles and a plurality of ejector sleeves both arranged on the thimble plate and penetrating through the lower die core to extend to the surface, an inclined rod arranged on the thimble plate and penetrating through the lower die core to extend to the surface, and inner needles arranged on the bottom plate and penetrating through the ejector sleeves. In a die opening state, the product on the surface of the lower die core is adsorbed by a mechanical arm, the inner needles, the thimbles and the inclined rod are balanced in advance to eject the product, the ejector sleeves are jacked to be higher than the surface of the inner needles for secondary ejection of the product, and the surfaces of theinner needles and the thimbles are each provided with a grid reverse buckling structure. Balanced ejection of the product reverse buckling structures is realized, the precision is guaranteed, and dieopening is stable.

Description

technical field [0001] The invention belongs to the technical field of molds, and in particular relates to a secondary ejection mold structure for anti-adhesive products. Background technique [0002] For anti-sticking products on the mirror surface, due to its special structure, the product has an undercut structure, and the inclined top column can exit the side mold without hindrance in the avoidance position. Guarantee the molding quality of the product. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned technical problems, and provide a secondary ejection mold structure for anti-sticking products, so as to realize the balanced ejection of the undercut structure of the product, ensure the precision, and stabilize the mold opening. In order to achieve the above object, the technical scheme of the present invention is as follows: [0004] Anti-sticking product secondary ejection mold structure, including the lower mold...
