Description

A kind of injection mold
Technical field
The present invention relates to a kind of injection mold.
Background technology
During design injection mold, if when master mold has overhead kick, also accordingly there is overhead kick the same with male model, need to have 2 ejector retainner plates to coordinate oblique top to take off overhead kick.The principle of this structure is: in the time of the die sinking of male and female die, master mold needle plate due to excellent power collagen because of, start to move down, in master mold, oblique top also moves thereupon simultaneously, until disengaging overhead kick is wherein also provided with the guide pillar that runs through upper bolster, stripper plate, upper ejector retainner plate, lower ejector retainner plate and caster, guide pillar is responsible for the needle plate that leads, prevent oblique top offset, card breaks.
This type of solves overhead kick mode need to go up ejector retainner plate and lower ejector retainner plate at 2 blocks of plates of the inner increase of template, so corresponding mould bases just needs increasing, waste material and resource.
Summary of the invention
The present invention is intended at least solve one of technical problem existing in prior art.
For addressing the above problem, the present invention proposes a kind of injection mold, comprising: stripper plate; Caster, described caster is located at the below of described stripper plate; Mother module core and male die core, described mother module core is located at the below of described caster, and described male die core is located at the below of described mother module core, forms the die cavity for the treatment of injecting products between mother module core and male die core; Oblique top, described oblique top upper end is fixed on described stripper plate, oblique through described caster and mother module core downwards, and matches with master mold overhead kick position in the lower end of described oblique top; With described oblique top is upwards applied in oblique direction to the elastic mechanism of elastic force, and described oblique top is moved and carries out spacing position-limit mechanism in oblique direction.
According to injection mold of the present invention, be three template dies, utilize cleverly three template die mold-opening structures to depart from master mold overhead kick, male and female template is before die sinking, between stripper plate and caster by first die sinking, oblique top is ejected disengaging overhead kick by elastic mechanism, in the time of the die sinking of male and female template, and overhead kick has departed from, so solve master mold overhead kick problem.With respect to prior art, injection mold of the present invention need not increase upper ejector retainner plate and lower ejector retainner plate, thus the present invention have easy for installation, processing is simple, master mold overhead kick mode is ingenious, demand space is little, the feature cutting the waste.
In addition, according to injection mold of the present invention, also there is following additional technical feature:

The specific embodiment
Describe embodiments of the invention below in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has the element of identical or similar functions from start to finish.Below by the embodiment being described with reference to the drawings, be exemplary, only for explaining the present invention, and can not be interpreted as limitation of the present invention.
In description of the invention, unless otherwise prescribed and limit, it should be noted that, term " installation ", " being connected ", " connection " should be interpreted broadly, for example, can be mechanical connection or electrical connection, can be also the connection of two element internals, can be to be directly connected, also can indirectly be connected by intermediary.For the ordinary skill in the art, can understand as the case may be the concrete meaning of above-mentioned term.
Below with reference to Fig. 1,2, describe according to a kind of injection mold of the embodiment of the present invention.As shown in Figure 1, 2, injection mold of the present invention comprises female die seat 1, stripper plate 2, caster 3, mother module core 4, male die core 5, male model plate 6, male die seat 7 and oblique top 8.
Stripper plate 2 is located at the below of female die seat 1; Caster 3 is located at the below of described stripper plate 2; Described mother module core 4 is located at the below of described caster 3, and described male die core 5 is located at the below of described mother module core 4, forms the die cavity for the treatment of injecting products between mother module core 4 and male die core 5; Male model plate 6 is located at the below of male die core 5, and male die seat 7 is located at the below of male model plate 6.Oblique top 8 upper ends are fixed on described stripper plate 2, oblique through described caster 3 and mother module core 4 downwards, and match with master mold overhead kick position in the lower end of described oblique top 8; Described oblique top 8 is upwards applied to the elastic mechanism of elastic force in oblique direction, and described oblique top 8 is moved and carries out spacing position-limit mechanism in oblique direction.
According to injection mold of the present invention, be three template dies, utilize cleverly three template die mold-opening structures to depart from master mold overhead kick, male and female template 3 is before die sinking, and elastic force oblique top 8 being made progress by elastic mechanism, makes between stripper plate 2 and caster 3 by first die sinking, oblique top 8 is ejected disengaging overhead kick by elastic mechanism, meanwhile, position-limit mechanism can prevent isolated by filtration between stripper plate 2 and caster 3, when the two is separated to a certain degree, can not be separated again, naturally make 4 separation of male and female die.And in the time of 4 die sinking of male and female die, and overhead kick has departed from, so solve master mold overhead kick problem.
Particularly, as shown in Figure 2, described elastic mechanism and position-limit mechanism comprise spring groove 9, spring 10, side projection 11, stopper slot 12, caging bolt 13, set bolt 14 and bolt 15.Side projection 11 is positioned at a side of described oblique top 8, is provided with stopper slot 12 in side projection 11; Spring groove 9 is located in described caster 3 and/or mother module core 4, and spring is positioned at described spring groove 9, and the upper end of described spring is connected with described side projection 11; Caging bolt 13 upper ends have limiting stand, and limiting stand is positioned at described stopper slot 12, and lower end is fixed on the lower end of spring groove 9 through described spring.This is simple in structure, easy for installation, durable, and between stripper plate 2 and caster 3, die sinking is sensitive, rapid.Meanwhile, caging bolt 13 plays the effect of lower link bar in conventional three template dies, saves lower link bar, makes simple for structure, easy to install and use.
The installation direction of described spring is identical with the oblique moving direction of described oblique top 8.The installation direction of described caging bolt 13 is identical with the oblique moving direction of described oblique top 8.Like this, make the elastic force of spring and direction that oblique top 8 moves consistent, the installation direction of caging bolt 13 can reduce the friction between caging bolt 13 and other structure of mould.
In addition, the lower end of described caging bolt 13 is fixed on described mother module core 4.Described caging bolt 13 models are M8*50.Make like this installation of caging bolt 13 more firm, to the spacing guaranteeing role that plays.
The upper end of described oblique top 8 is fixed on stripper plate 2 by set bolt 14.Like this, make oblique top 8 detachable and replaceable.Fixing by bolt 15 between described caster 3 and mother module core 4.
