Abstract
The invention provides a reset structure for a floating insert of a forced demolding mould, which is characterized in that on the premise of ensuring the appearance requirement of a product, the reliable reset of the floating insert is ensured. The reset structure for the floating insert of the forced demolding mould comprises a plate A, a front mould core, a rear mould core, a plate B, an ejector plate, an ejector base plate, a lower fixed plate and the floating insert, wherein the upper end of the floating insert extends into a cavity body formed when mould closing is carried out on the front mould core and the rear mould core; the rear mould core is provided with a floating insert linear hole; an ejector at the lower part of the floating insert penetrates through the floating insert linear hole; and floating distance slot bodies are respectively arranged in an ejector at the lower part of the floating insert and the floating insert linear hole. The reset structure for the floating insert of the forced demolding mould is characterized in that a through hole is arranged at the position on the ejector base plate, which corresponds to the ejector at the lower part of the floating insert; an ejector supporting piece is arranged in the through hole; the ejector supporting piece is fastened and connected with the lower fixed plate; and the ejector at the lower part of the floating insert is supported onto a top pillar supporting piece after penetrating through the rear mould core, the plate B and the ejector plate in sequence.
Description
Technical field
The present invention relates to the technical field of structures of injection mould mould, be specially the unsteady mold insert resetting structure of forced stripper mechanism mould.
Background technology
In the mould structure design, can run into the product structure of forced stripper mechanism once in a while.Usually all be the structure that adopts the mold insert that floats, mold insert is under the effect of product back-off, and after product ejected a segment distance, after die cavity was deviate from the back-off periphery of product, after the mold insert that floats was limited, ejecting mechanism ejected product by force from the back-off mold insert.But this structure receives the limitation of product structure design, and a through hole (bumping perforation) must be arranged near the product back-off, is used for resetting to the unsteady mold insert that is ejected die surface; When matched moulds; Dependence is bumped the perforation structure mold insert that will float and is pushed back the initial position in when design, but for the product that strict appearance requirement is arranged, can not design near its back-off and bump perforation; If we adopt common structure again, just can't guarantee the reliable reset of unsteady mold insert.
Summary of the invention
To the problems referred to above, the invention provides the unsteady mold insert resetting structure of forced stripper mechanism mould, it makes is guaranteeing to guarantee the reliable reset of unsteady mold insert under the prerequisite that product appearance requires.
The unsteady mold insert resetting structure of forced stripper mechanism mould; Its technical scheme is such: it comprises A plate, preceding die, back die, B plate, ejector retainner plate, end needle plate, bottom plate, mold insert floats; The cavity that the upper end of said unsteady mold insert forms when stretching into said preceding die, back die matched moulds; Said back die has the mold insert straight hole that floats; The bottom thimble of said unsteady mold insert runs through said unsteady mold insert straight hole; Be provided with in the bottom thimble of said unsteady mold insert and the said unsteady mold insert straight hole and float apart from cell body, it is characterized in that: the position of the bottom thimble of the corresponding said unsteady mold insert of needle plate of the said end has through hole, and the thimble support member is housed in the said through hole; Said thimble support member is fastenedly connected said bottom plate; The bottom thimble of said unsteady mold insert is supported on said fore-set support member after running through said back die, B plate, ejector retainner plate successively, and the bottom of the bottom thimble of said unsteady mold insert is a male structure outside the both sides, and said both sides evagination respective outer side edges is installed in the bottom evagination cell body of said ejector retainner plate.
It is further characterized in that: the cross section structure of the bottom thimble of said unsteady mold insert is up-small and down-big structure; Said unsteady mold insert straight hole is up-small and down-big structure, the cell body that distance constituted that exists between the little big interface of the said unsteady bottom thimble that is specially said unsteady mold insert apart from cell body and the little big interface of said unsteady mold insert straight hole.
After adopting said structure of the present invention; Because the position of the bottom thimble of the corresponding said unsteady mold insert of end needle plate has through hole, ejector retainner plate can not have active force to the bottom thimble of the mold insert that floats when ejecting state. the bottom thimble of the mold insert that floats becomes quick condition; Lean on back-off on the product to float after mold insert takes mold cavity one segment distance together out of; After the mold insert that floats was limited, product continued to be ejected by thimble, accomplishes out the demoulding of product; After product was ejected die cavity by thimble, ejector retainner plate was understood the bottom thimble of the mold insert that will float and is taken back original initial position in reseting procedure, no longer need bump perforation, was guaranteeing to guarantee the reliable reset of unsteady mold insert under the prerequisite that product appearance requires so it makes.
Description of drawings
Fig. 1 is a front view structural representation of the present invention;
Fig. 2 is the A place partial enlarged drawing structural representation of Fig. 1.
The specific embodiment
See Fig. 1, Fig. 2; It comprises A plate 1, preceding die 2, back die 3, B plate 4, ejector retainner plate 5, end needle plate 6, bottom plate 7, mold insert floats; The cavity 9 that the mold insert part 8 of unsteady mold insert forms when stretching into preceding die 2, back die 3 matched moulds; Back die 3 has the mold insert straight hole 10 that floats, and the bottom thimble 11 of the mold insert that floats runs through the mold insert straight hole 10 that floats, and is provided with in the bottom thimble 11 of the mold insert that floats and the unsteady mold insert straight hole 10 and floats apart from cell body 18; The position of the bottom thimble 11 of the end needle plate 6 corresponding mold inserts that float has through hole 12; Thimble support member 13 is housed in the through hole 12, and thimble support member 13 is fastenedly connected bottom plate 7, and the bottom thimble 11 of the mold insert that floats is supported on fore-set support member 13 after running through back die 3, B plate 4, ejector retainner plate 5 successively; The bottom of the bottom thimble 11 of unsteady mold insert is a male structure 14 outside the both sides, and male structure 14 cooperations are installed in the bottom evagination cell body 15 of ejector retainner plate 5 outside the both sides.The cross section structure of the bottom thimble 11 of unsteady mold insert is up-small and down-big structure; The mold insert straight hole 10 that floats be up-small and down-big structure, floats and is specially the cell body that distance constituted of 17 existence of little big interface of little big interface 16 and unsteady mold insert straight hole 10 of the bottom thimble 11 of unsteady mold insert apart from cell body 18.
