Description
Technical field
The utility model relates to die casting technical fields, more particularly to a kind of delayed ejection applied to die casting
Structure.
Background technique
Aluminium horizontal board mount just can determine that whether its quality is qualified, influences flat aluminium alloy plate branch in in-mold molding
The principal element of frame quality comes from the structure of mold, mold design it is structurally reasonable, flat aluminium alloy plate can be substantially reduced
The disqualification rate of bracket.When producing aluminium horizontal board mount, since blank product reverse side muscle is thicker, answered after product die casting
Power contraction causes the deformation of blank middle section larger, and product sticks out.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of delayed ejection structure applied to die casting, knots
The advantages that structure inferior rate simple, easy to use, that reduce aluminium horizontal board mount.
The technical scheme adopted by the utility model to solve the technical problem is as follows: providing a kind of prolonging applied to die casting
Slow ejecting structure, including upper die holder, upper mold core and lower mold core are equipped with lower die holder on the lower end surface of the upper die holder, described
Upper die holder and lower die holder between be equipped in stacking the upper mold core and lower mold core of installation, between the upper mold core and lower mold core
Form die cavity, the lower die holder lower end two sides are mounted on support block, between two support blocks from top to bottom successively upper plate and under
Top plate, the lower end of two support blocks are equipped with back cover plate, several upper ends are provided in the middle part of the upper plate and are inserted into die cavity
Central ejector rod, the two sides of the upper plate are provided with the side mandril that several upper ends are inserted into die cavity, position in the lower roof plate
It is vertically arranged with through-hole below each central ejector rod, a circle avoiding hollow groove, the envelope are provided at the through-hole upper end opening
Several pad posts to match with central ejector rod are provided on bottom plate, which passes through through-hole and withstand central ejector rod lower end.
As a kind of supplement to technical solution described in the utility model, the depth of the avoiding hollow groove is 5mm.
As a kind of supplement to technical solution described in the utility model, pass through between the upper plate and lower roof plate
Screw is fixed.
The utility model has the advantages that the utility model relates to a kind of delayed ejection structure applied to die casting, pad post is fixed on envelope
Central ejector rod is withstood on bottom plate, when upper plate and lower roof plate eject together, central ejector rod lower end is trapped in avoiding hollow groove before this
Interior, central ejector rod, which just rises, later to eject in the middle part of product, and then direct products two sides eject the side mandril of two sides, central ejector rod
It is fewer than side mandril to eject 5mm, mechanism is withstood in this way to guarantee the product depth of parallelism, so that the depth of parallelism of blank is all in 0.8mm
Within.This is practical also to have many advantages, such as that structure is simple, inferior rate easy to use, reducing aluminium horizontal board mount.

Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
The embodiments of the present invention is related to a kind of delayed ejection structure applied to die casting, as shown in Figs. 1-2,
Including upper die holder, upper mold core and lower mold core 1, lower die holder is installed on the lower end surface of the upper die holder, the upper die holder and
It is equipped between lower die holder in the upper mold core and lower mold core 1 for stacking installation, forms mould between the upper mold core and lower mold core 1
Chamber, the lower die holder lower end two sides are mounted on support block, successively upper plate 3 and lower roof plate 4 from top to bottom between two support blocks,
The lower end of two support blocks is equipped with back cover plate 5, and the middle part of the upper plate 3 is provided with several upper ends and is inserted into die cavity
Heart mandril 8, the two sides of the upper plate 3 are provided with the side mandril 2 that several upper ends are inserted into die cavity, position in the lower roof plate 4
It is vertically arranged with through-hole 9 in each 8 lower section of central ejector rod, a circle avoiding hollow groove 6 is provided at 9 upper end opening of through-hole, it is described
Back cover plate 5 on be provided with the pad post 7 that several and central ejector rod 8 match, which passes through through-hole 9 and withstands central term
8 lower end of bar.Pad post 7, which is fixed on back cover plate 5, withstands central ejector rod 8, when upper plate 3 and lower roof plate 4 eject together, center
8 lower end of mandril was trapped in front of this in avoiding hollow groove 6, and central ejector rod 8, which just rises, later to eject in the middle part of product, and the side mandril of two sides
2 direct products two sides ejections, central ejector rod 8 is fewer than side mandril 2 to eject 5mm, withstands mechanism in this way to guarantee that product is flat
Row degree, so that the depth of parallelism of blank is all within 0.8mm.Pad post 7 can be replaced, and the pad post 7 of different height in a disguised form changes
The depth of avoiding hollow groove 6, for example, central ejector rod 8 is than the few ejection of side mandril 2 when 7 upper end of pad post is flushed with 6 bottom surface of avoiding hollow groove
5mm, when 7 upper end of pad post is higher than 6 bottom surface 1mm of avoiding hollow groove, central ejector rod 8 is fewer than side mandril 2 to eject 4mm.
The depth of the avoiding hollow groove 6 is 5mm.
It is fixed between the upper plate 3 and lower roof plate 4 by screw.
Above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；Although referring to aforementioned reality
It applies example the utility model is described in detail, it will be understood by those of skill in the art that it still can be to aforementioned each
Technical solution documented by embodiment is modified, or is replaced on an equal basis to part of technical characteristic；And these are modified
Or replacement, the spirit and scope for various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution.
