Abstract
A kind of synchronous hook mould emptier being applied to interior division buffer bar, include mould bases, draw hook system and ejection system, this mechanism ejects motion by oil cylinder pushing ejection system, because drag hook is fixed on push rod base plate and its head hooks die cavity, cavity plate is moved together with ejection system with product, instead of the direct disengaging of die cavity and core, ensure that the back-off face of die cavity is not pulled, after ejecting one section, due to the effect of oblique top system and shift rail mechanism, deformation of products is driven to deviate from die cavity, now synchronous hook is due to after varied orbit, drag hook deviates from die cavity to inner rotary, make the normal die sinking of die cavity, the complete demoulding of product is realized again by the secondary ejecting mechanism of oil cylinder.
Description
Technical field
The utility model belongs to injection mould field, is specifically related to a kind of synchronous hook mould emptier being applied to interior division buffer bar.
Background technology
The front/rear collision bumper of car is its appearance ornamental pieces, adopts outer somatotype parting, production out after on its visible surface, have one to breathe out furan line, have impact on the presentation quality of car.This Appearance quality defect makes manufacturer not accept, and requirement must adopt the interior parting structure demoulding, eliminates parting line in product external surfaces.Interior parting structure requires that first die cavity and product are synchronized with the movement, and when driving bumper distortion to deviate from die cavity after the oblique top demoulding to a certain extent, therefore application of synchronized demoulding with hooks mechanism makes product smooth demoulding from die cavity be the key of current Project Technical.
Utility model content
For Problems existing in above-mentioned technology; the purpose of this utility model is to provide a kind of synchronous hook mould emptier being applied to interior division buffer bar; achieve die cavity and product is synchronized with the movement, enable the parting line of bumper product turn to interior somatotype to realize, improve the quality of product.
Above-mentioned purpose, is achieved through the following technical solutions:
A kind of synchronous hook mould emptier being applied to interior division buffer bar, include mould bases, draw hook system and ejection system, mould bases comprises cavity plate, core plate, mould pin, push rod panel, push rod baffle plate and core fixing plate, it is characterized in that: described draw hook system includes die cavity locating piece, spring, inside contracts bullet block, limited block, drag hook locating piece, drag hook, fixed block, positioning guide rail block, locating piece, guiding rail block, bearing, bearing dowel, drag hook rotating dog, jump ring and drag hook location backing plate; Drag hook lower end is fixed on top board base plate and drag hook head hooks cavity plate.
This mechanism ejects motion by oil cylinder pushing ejection system, because drag hook is fixed on push rod base plate and its head hooks die cavity, cavity plate is moved together with ejection system with product, instead of the direct disengaging of die cavity and core, ensure that the back-off face of die cavity is not pulled, after ejecting one section, due to the effect of oblique top system and shift rail mechanism, drive deformation of products to deviate from die cavity, now synchronous hook is due to after varied orbit, drag hook deviates from die cavity to inner rotary, makes the normal die sinking of die cavity; The complete demoulding of product is realized again by the secondary ejecting mechanism of oil cylinder.
Eject motion by push rod baffle plate, drive straight jacking block to be pressed in by product die cavity keeps static and synchronously do die sinking campaign with die cavity, and deviating from die cavity by deformation of products, solving the release problems in interior typing mechanism cavity side back-off face.The application of synchronous mold-opening mechanism; outer for bumper parting structure design has been risen to designing and developing of interior parting structure; improve the quality of bumper product, make the research and development space of product serviceability and appearance design effect more open, there is DEVELOPMENT PROSPECT and business development meaning widely.
Superiority of the present utility model is:
1, synchronous hook structure is simple, easy for installation, and product, die cavity and ejecting mechanism are synchronized with the movement to adopt frame for movement to ensure, make mould safe and efficient and can ensure the mold use life-span.
2, synchronous hook structure ensure that the smooth realization of other labyrinth, uses this mechanism to reduce die cost; Avoid using more loose core of oil cylinder installing hole, and oil cylinder accounts for too many die space too much, affect Hoisting Security and the oil circuit arrangement of mould.
3, the synchronous hook mechanism of interior division buffer bar is the mechanism used in mould widely, and this structure is not only confined to the application of bumper mold mechanism, has novel innovative significance and market application foreground widely.
Accompanying drawing explanation
Fig. 1 is the interior somatotype schematic diagram of division buffer bar in the utility model.
Fig. 2 is the synchronous hook mould emptier structural representation of division buffer bar in the utility model;
Fig. 3 is the axle side diagram of the synchronous hook mould emptier of division buffer bar in the utility model;
Fig. 4 is the utility model draw hook system structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, for the utility model needs die joint somatotype process in realization, object product external surfaces being eliminated parting line is reached.
As in Figure 2-4, a kind of synchronous hook mould emptier being applied to interior division buffer bar, includes mould bases, draw hook system and ejection system, and wherein mould bases comprises cavity plate 1, core plate 2, mould pin 3, push rod panel 4, push rod baffle plate 5 and core fixing plate 6; Draw hook system comprises die cavity locating piece 7, spring 8, inside contracts bullet block 9, limited block 10, drag hook locating piece 11, drag hook 12, fixed block 13, positioning guide rail block 14, locating piece 15, guiding rail block 16, bearing 17, bearing dowel 18, drag hook rotating dog 19, jump ring 20, drag hook location backing plate 21.When oil cylinder drives push rod panel 4, when push rod baffle plate 5 and draw hook system upwards eject motion, because drag hook locating piece 11 hooks die cavity locating piece 7, and the starting stage of guiding rail block 16 is vertical, bearing 17 does upward vertical movement along guiding rail block 16, drag hook effect makes the straight jacking block of ejection system product be pressed to cavity plate 1 to be synchronized with the movement as geo-stationary, pitched roof mechanism then ejects simultaneously to be done with interior twitch, and the deformation space of product is provided, after bearing 17 outwards becomes rail along guiding rail block 16, drag hook 12 is because drag hook rotating dog 19 is to inner rotary, drag hook locating piece 11 exits die cavity locating piece 7, after making cavity plate 1 depart from drag hook, automatic die sinking departs from product, ejection system continues to eject product.When mould resets, first eject reset, until ejection system reset to drag hook 12 inwardly spinning reduction time, cavity plate 1 starts matched moulds, and drag hook 12 head inclined-plane first contacts with the inclined-plane, bottom side inside contracting bullet block 9, makes to inside contract bullet block 9 and acts on to inside contracting by spring 8, drag hook locating piece 11 is by after inside contracting bullet block 9, spring 8 makes to inside contract the fast band of bullet block 9 and resets, after drag hook locating piece 11 and die cavity locating piece 7 are accurately located, and cavity plate 1 and ejection system synchronous reset.
