Abstract
The utility model discloses a multi-section ejection die-opening component for a cigarette lighter outer cover. The die-opening component has a multi-layer structure based on a rear die, wherein the rear die is provided with a mould core and an insert which correspond to the shape of the cigarette lighter outer cover; and the insert is sleeved at the periphery of the mould core and is matched with a clamping pin of the cigarette lighter outer cover. In particular, the insert comprises a first insert opposite to the outer side of the clamping pin and a second insert opposite to the inner side of the clamping pin; the die-opening component comprises a first base plate, a second base plate and a core-withdrawing plate, which are combined with the first insert, the second insert and the mould core respectively and are driven by a rear die driving device program-controlled by an injection moulding machine to depart from or move towards the front die; and the first base plate is a part subjected to die withdrawing firstly by the die-opening component. According to application of the die-opening component, the defect that the mould core is difficult to withdraw during die opening because the product is clamped by the clamping pin tightly can be effectively overcome; and possibility of die-withdrawing damage of the product is reduced and the whole qualification rate is increased.
Description
Technical field
The utility model relates to a kind of injection mold to be improved, and relates in particular to a kind of die sinking assembly of injection mold.
Background technology
The cigar lighter enclosing cover is a kind of auxiliary part that is used to make automobile cigarette lighter, under the cap structure of circle, has two above card bases, is used for the cigar lighter clamping and makes cigar lighter dust, moisture contamination.This cigar lighter enclosing cover is generally plastic cement material, through the integrated through injection molding moulding.
Because card base keeps the inwardly state of clamping in injection moulding process; Thereby the die sinking after moulding, move back in the mold process; Can mold insert take place usually, card base only wraps core, and the unusual increase of moving back the mould resistance is caused in the space that the card base outside does not have elasticity to open outward; What is more in moving back mold process, be easy to the to wear and tear cigar lighter enclosing cover of moulding causes the deviation of finished product and cigar lighter clamping performance.
Summary of the invention
In view of the defective that above-mentioned prior art injection mold partly exists in die sinking, the purpose of the utility model is to propose a kind of novel multistage to eject the die sinking assembly, improves the moulding quality of automobile cigarette lighter enclosing cover.
The purpose of the utility model will be achieved through following technical scheme:
The multistage of cigar lighter enclosing cover ejects the die sinking assembly; This die sinking assembly is the multi-layer compound structure based on the back mould; Said back mould is provided with core and mold insert corresponding to cigar lighter enclosing cover shape; It is peripheral and agree with the card base of cigar lighter enclosing cover that said mold insert is socketed in core, it is characterized in that: said mold insert comprises first mold insert in the relative card base outside and the second inboard mold insert of card base relatively, and said die sinking assembly comprises:
First backing plate, combining also with first mold insert, the one edge deviates from or moves towards the direction of front mould;
Second backing plate, combining also with second mold insert, the one edge deviates from or moves towards the direction of front mould;
Move back central layer, combine also the one edge deviates from or moves towards the direction of front mould with core;
Said first backing plate, second backing plate and move back central layer and be connected the program control back mould drive unit of injection machine respectively.
Further, said first backing plate is combined as a whole through fixed head and screw and first mold insert.
The application of the utility model die sinking assembly; Adjustment to Shooting Technique die sinking part; Compare to prior art: the core that causes because of product card base banding in the time of effectively overcoming die sinking moves back the mould difficulty, has reduced product simultaneously and has moved back the possibility that wear is hindered, and has improved whole yields.
Following constipation closes the embodiment accompanying drawing, the specific embodiment of the utility model is done further to detail, so that the utility model technical scheme is easier to understand, grasp.
Description of drawings
Fig. 1 is the utility model cigar lighter enclosing cover injection moulding processed mould structural representation.
The specific embodiment
As shown in Figure 1, be cigar lighter enclosing cover injection moulding processed mould structural representation.Visible from illustrating: the product of mould structure under this matched moulds state and wherein injection mo(u)lding comes into plain view.Mainly comprise front mould 1, back mould 2 is located at a core 8, mold insert on the mould of back, and the cigar lighter enclosing cover of injection mo(u)lding therebetween.The die sinking assembly of the utility model then is the multi-layer compound structure based on back mould 2.Especially; The utility model is done the separate type design to traditional mold insert; The interior outside of card base that is relative cigar lighter enclosing cover is provided with mutually independently two mold inserts respectively, and first mold insert 3 in the card base outside is socketed on the second inboard mold insert 7 of card base, and second mold insert 7 is socketed in again on the core 8.Wherein second mold insert 7 is longer than first mold insert 3.
For further be convenient to mold insert, core moves back mould; Be provided with first backing plate 9 corresponding to above-mentioned first mold insert 3; And this first backing plate 9 is combined as a whole with first mold insert through fixed head 4 and screw (not sign), and this first backing plate 9 links to each other with the program control back mould drive unit of injection machine and be controlled; Be provided with second backing plate 10 and second fixed head 5 is integrated as one with it corresponding to above-mentioned second mold insert 7, this second backing plate 10 links to each other with the program control back mould drive unit of injection machine and is controlled; Be provided with corresponding to above-mentioned core 8 and move back central layer (not shown) and core fixing plate 6, this moves back that central layer also links to each other with the program control back mould drive unit of injection machine and is controlled.
During die sinking; By first backing plate 9 running in advance of injection machine program control driving; First mold insert 3 is separated from the card base outside of cigar lighter enclosing cover, reduce coating power with this, so that when next withdrawing from second mold insert 7 to core; Card base can have enough spaces outwards to part a little, and is unlikely to the scratch card base or causes cigar lighter enclosing cover finished product to scrap.Cigar lighter enclosing cover finished product after this ejects with traditional handicraft consistent, will not give unnecessary details now.
Visible through above description: the application of the utility model die sinking assembly; Adjustment to Shooting Technique die sinking part; The core that causes because of product card base banding in the time of effectively overcoming die sinking moves back the mould difficulty, has reduced product simultaneously and has moved back the possibility that wear is hindered, and has improved whole yields.
