Abstract
The utility model provides a structure for preventing abrasion between an insert on one side and a rear mold. By means of the structure, the abrasion between the insert on one side and the rear mold is decreased, the accuracy of the mold is guaranteed, the service life of the mold is long, the quality of an injection product is good, and the production cost is finally reduced. The structure comprises a front mold, a rear mold, a plate A and a plate B, wherein a cavity is formed between the front mold and the rear mold, a hole-type insert is located in the cavity on the corresponding side, and the hole-type insert is supported on the rear mold during mold closing. The structure is characterized in that a gap is reserved between a base plate at the bottom and the plate B, and the base plate is tightly connected with a lower panel; bottoms of at least two ejector pins are fastened in positioning cavities formed by the panel and the base plate, tops of the ejector pins penetrate through the plate B and the rear mold and then are abutted against the bottom end surface of the hole-type insert, and abrasion-resistant rubber cushions are arranged at the tops of the ejector pins; and the top of an upper ejector rod is propped against the bottom end surfaces of the ejector pins and located in a lower limiting cavity formed by the panel and the base plate.
Description
Technical field
The utility model relates to the technical field of structures of product mold, is specially the anti-wear structure between a side mold insert and rear mold.
Background technology
The mould of the product of one side band through hole, die cavity one side that is specially mould arranges pass mold insert, and pass mold insert is fastenedly connected the line position piece of a side, during the demoulding, line position piece makes pass mold insert complete to loose core under the drive of Angle Pin, the bottom face of pass mold insert directly contacts with rear mold, in bottom face and the rear mold generation wearing and tearing of knockout course mesothyrid mold insert, of long duration, the precision of mould will decline, and then make the of poor quality of injecting products, and the life-span of mould is short, and production cost is high.
Summary of the invention
The utility model provides the anti-wear structure between a side mold insert and rear mold, and it diminishes the wearing and tearing between a side mold insert and rear mold, has guaranteed the precision of mould, makes the life-span of mould long, and the quality of injecting products is good, has finally reduced production cost.
Anti-wear structure between one side mold insert and rear mold, its technical scheme is such: it comprises front mould, rear mold, A plate, B plate, described front mould, it between rear mold, is die cavity, pass mold insert is positioned at the die cavity of respective side, described pass mold insert during matched moulds is supported on described rear mold, it is characterized in that: between the backing plate of bottom and B plate, leave gap, described backing plate is fastenedly connected the panel of bottom, the bottom of thimble is anchored on described panel, in the formed positioning chamber of backing plate, described thimble has at least two, described B plate is run through at the top of described thimble, after rear mold, be mounted on the bottom face of described pass mold insert, the top of described thimble is provided with abrasion-proof rubber cushion, the top of upper ejector pin is mounted on the bottom face of described thimble, the top of described upper ejector pin is positioned at described panel, in the limit chamber of the formed bottom of backing plate.
Adopt after structure of the present utility model, because the top of thimble is mounted on pass mold insert after running through B plate, rear mold, and the top of thimble is provided with abrasion-proof rubber cushion, it makes the bottom face part gravity of pass mold insert be supported on abrasion-proof rubber cushion, when pass mold insert and rear mold generation wearing and tearing, it diminishes wearing and tearing, and abrasion-proof rubber cushion is convenient for changing, it guarantees the longitudinal register of pass mold insert, guaranteed the precision of mould, make the life-span of mould long, the quality of injecting products is good, has finally reduced production cost; In addition, after pass mold insert completes and looses core, under the effect of upper ejector pin, panel, backing plate drive thimble to rise, until thimble ejects rear mold by the product in die cavity, complete product stripping, because the top of thimble is provided with abrasion-proof rubber cushion, it can not destroy the surface of product.
Accompanying drawing explanation
Fig. 1 is front view structural representation of the present utility model.
The specific embodiment
See Fig. 1, it comprises front mould 1, rear mold 2, A plate 3, B plate 4, front mould 1, it between rear mold 2, is die cavity 5, pass mold insert 6 is positioned at the die cavity 5 of respective side, pass mold insert 6 during matched moulds is supported on rear mold 2, backing plate 7 and 4 of the B plates of bottom leave gap, backing plate 7 is fastenedly connected the panel 8 of bottom, the bottom of thimble 9 is anchored on panel 8, in the formed positioning chamber 10 of backing plate 7, B plate 4 is run through at the top of thimble 9, after rear mold 2, be mounted on the bottom face of pass mold insert 6, thimble 9 has at least two, the top of thimble 9 is provided with abrasion-proof rubber cushion 11, the top of upper ejector pin 12 is mounted on the bottom face of thimble 9, the top of upper ejector pin 12 is positioned at panel 8, in the formed bottom of backing plate 7 limit chamber 13.
