Abstract
The utility model provides a secondary demolding ejector pin mounting structure of a mold. The mounting structure allows the mold to be simple in structure and low in manufacturing cost when a product requires secondary demolding. The mounting structure comprises a B plate, insert ejector pins, a product ejector pin, a surface pin plate and a bottom pin plate, wherein the upper end face of the product ejector pin is clung to the lower end face of the product, and the upper end faces of the insert ejector pins fasten the lower end faces of inserts. The mounting structure is characterized in that the surface pin plate comprises an upper surface pin plate and a lower surface pin plate; the upper surface pin plate and the lower surface pin plate are fastened, mounted and connected; the product ejector pin is fixedly mounted in a mounting groove formed by combining the upper surface pin plate and the lower surface pin plate; a nylon shutter is connected with the lower surface pin plate and the bottom pin plate; the lower parts of the insert ejector pins penetrate through the upper surface pin plate and the lower surface pin plate respectively, and then are fastened with the bottom pin plate; and a cavity is reserved between the B plate and the upper surface pin plate.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is specially a kind of secondary demoulding thimble mounting structure of mould.
Background technology
The secondary demolding structure of existing mould, it will use two groups of face needle plates, end needle plate, and it needs the volume of mould large, and structure installation is complicated, makes the cost of mould high.
Summary of the invention
The utility model provides a kind of secondary demoulding thimble mounting structure of mould, and when it makes the demoulding of product needed secondary, mould structure is simple, cost of manufacture is low.
A secondary demoulding thimble mounting structure for mould, its technical scheme is such: it comprises B plate, mold insert thimble, product thimble, face needle plate, end needle plate, the lower surface of product is close in the upper surface of described product thimble, and the lower surface of the fastening mold insert in upper surface of described mold insert thimble, is characterized in that: described needle plate comprises needle plate above, needle plate below, described needle plate above, the fastening installation of needle plate below connects, and described product thimble is installed in described needle plate above, in the mounting groove that needle plate is combined to form below, nylon shutter connects described needle plate below, end needle plate, described needle plate is above run through respectively in the bottom of described mold insert thimble, after needle plate, be anchored on needle plate of the described end below, described B plate, between needle plate, leave cavity above, the lower surface of described B plate is fastenedly connected with the block of arranging downward vertically, and the bottom of described block is described needle plate above deeply, in the perforation gathering sill of needle plate, needle plate of the described end has top roller through hole below, and top roller is fastenedly connected described needle plate below after running through described top roller through hole.
It is further characterized in that: the top of described nylon shutter is the described inside of needle plate above deeply.
Adopt after structure of the present utility model, after the moulding/demoulding of front and back, top rod promotes needle plate below and rises, due to the effect of nylon shutter, end needle plate is also driven together, and then a up top lifting, now, mold insert thimble, product thimble is by product, mold insert ejects together, top is after certain distance, the upper surface of end needle plate is close in the lower surface of block, mold insert thimble no longer rises, under top rod drives, needle plate below, end needle plate separates, thimble has the glue position in outside to go out rear mold, needle plate above, needle plate is again toward rising below, utilize the power of product thimble, product can be spun off by force from mold insert, it needs to use needle plate above, needle plate below, needle plate totally three blocks of plates in the end can form secondary demolding structure, mould structure is simple, cost of manufacture is low.
