Drawings
FIG. 1 is a schematic view of a moving mold;
FIG. 2 is a schematic view of a stationary mold structure;
reference numbers in the figures:
the device comprises a movable mould 1, a fixed mould 2, a vacuum negative pressure device 3, an air passage 4, a flow passage 5, a movable top block 6, a sealing ring 7, a first sealing ring 8, a second sealing ring 9, a body cavity 10, a hydraulic cylinder 11 and a piston rod 12.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
1-2, cover half 2 is the cylinder structure, be equipped with a plurality of vacuum negative pressure ware 3 on the movable mould 1, the inside mosaic of cover half 2 is equipped with movable kicking block 6, movable kicking block 6 with cover half 2 is movable to be connected, vacuum negative pressure ware 3 is equipped with air flue 4, vacuum negative pressure ware 3 pass through air flue 4 with movable mould 1 through connection, movable kicking block 6 can not move at the in-process of moulding plastics, also can not be in ejecting state suddenly, can exist in the inside of cover half 2 when not using, places can expend with heat and contract with cold when the product cools off at the inside reason of cover half 2, then will wrap up on the surface of cover half 2 tighter, and the movable kicking block 6 that just needs at this moment the drawing of patterns pushes up the product out.
