Abstract
The utility model relates to a mold insert structure of a plastic mould. The structure comprises a mold core and a mold insert, wherein the mold core comprises a mold core forming cavity region and a mold core non-forming cavity region, the mold core forming cavity region is arranged in the mold core non-forming cavity region, and a mold insert groove is formed on the mold core forming cavity region; the mold insert is provided with a mold insert forming cavity and a mold insert connecting part, the mold insert forming cavity is arranged in the mold insert groove on the mold core forming cavity region, and is in close fit with the mold insert groove; and the mold insert connecting part extends out of the mold insert forming cavity region, and is fixed on the mold insert nor-forming cavity region. Compared with the prior art, the mold insert is tightly fixed with the mold insert non-forming cavity region through the mold insert connecting part, so that threaded holes are prevented from being formed on the mold insert forming cavity region, and the forming quality of products is further guaranteed. At the same time, the mold insert can be quickly disassembled and replaced, so as to improve the production efficiency of moulds.
Description
Technical field the utility model relates to the internal structure of mould, relates in particular to a kind of mold insert structure of plastic mould.
Background technology is nearly all product such as household electrical appliance now, automobile, aircraft etc. all need to utilize mould make various parts, particularly plastics and metal die in the majority.Because the diversity of product variations, some parts has a plurality of styles, only has the difference of part between different styles.For the modification of this partial structurtes,, can process by using the different mold insert of mold collocation in order to save cost.The replacing process and the efficient of mold insert have just received much concern so.
At present, the lock mold insert generally has dual mode, and the one, lock behind from mold insert, the 2nd, by the positive locking of mold insert.Need descend machine to change when the mold insert of locking is changed from behind, such as injection mold, if because the requirement of producing need be replaced by other styles, usually need carry out machine under the mould, matched moulds is changed in form removal, steps such as last machine, and need correct die location again toward contact, the time that this process need is a large amount of, restricted the working (machining) efficiency of mould.Though from the mould of front locking can the realization machine on quick change, but because the structural limitations of mold insert, mold insert generally is to be fixed on the forming cavity zone of die by screw, therefore, the die forming cavity needs to offer the screwed hole that is used for fixing mold insert on the zone, so just may have influence on the molding effect of product in mould.
The summary of the invention the purpose of this utility model provides a kind of fast changeable mold insert and does not influence the mold insert structure of the plastic mould of formed product.
For achieving the above object, the utility model comprises die and mold insert; Described die comprises die forming cavity zone and the non-forming cavity of die zone, and die forming cavity zone is located in the non-forming cavity of the die zone, and die forming cavity zone is provided with the mold insert groove; Described mold insert is provided with mold insert forming cavity and mold insert connecting portion, and described mold insert forming cavity is arranged in the mold insert groove in die forming cavity zone, and closely cooperates with the mold insert groove; Described mold insert connecting portion extends die forming cavity zone, is fixed on the non-forming cavity of the die zone.Owing to adopt above structure, when changing mold insert, only mould need be in die opening state, can utilize common tool that mold insert is unloaded and be replaced by other mold inserts from mould, and need not machine under the mould.Because mold insert is to be connected on the non-forming cavity of the die zone by the mold insert connecting portion is dismountable, so just avoided offering screwed hole, thereby guaranteed the molding effect of product in the die in die forming cavity zone.
The non-forming cavity of die of the present utility model zone is provided with mold insert connecting portion mounting groove, and the mold insert connecting portion is provided with installing hole, and the position corresponding with installing hole, mounting groove bottom in the non-forming cavity of die zone is provided with screwed hole; The mold insert connecting portion is anchored in the mounting groove in the non-forming cavity of die zone by the installing hole that screw passes the mold insert connecting portion, the mold insert forming cavity can be anchored in the mold insert groove in die forming cavity zone accordingly.The mold insert connecting portion is fixed on by screw in the mounting groove in the non-forming cavity of die zone, during dismounting, extract mold insert after only need screw being screwed out and get final product with instrument, during installation, mold insert need be inserted the mold insert groove after DRIVE SCREWS get final product.This structure is in that to guarantee to make when mold insert is in place mold insert to change convenient.
Installing hole on the mold insert connecting portion of the present utility model is provided with the counterbore of taking in screw head.Make screw to enter fully in the mold insert connecting portion like this, thereby avoided screw to damage or make the mold insert deviation position because of collision.
In sum, compared with prior art, mold insert of the present utility model is fastening by mold insert connecting portion and the non-forming cavity of die zone, thereby has avoided offering screwed hole in die forming cavity zone, has guaranteed the Forming Quality of product.Simultaneously, realized quick detach quick change, improved the production efficiency of mould mold insert.
Description of drawings is described in further detail the utility model below in conjunction with the drawings and specific embodiments:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
The specific embodiment as shown in Figures 1 to 3, the utility model comprises die 1 and mold insert 4; Described die 1 comprises die forming cavity zone 2 and the non-forming cavity of die zone 3, and die forming cavity zone 2 is located in the non-forming cavity of the die zone 3, and die forming cavity zone 2 is provided with mold insert groove 21; Described mold insert 4 is provided with mold insert forming cavity 41 and mold insert connecting portion 42, and described mold insert forming cavity 41 is arranged in the mold insert groove 21 in die forming cavity zone 2, and closely cooperates with mold insert groove 21; Described mold insert connecting portion 42 extends die forming cavity zone 2, is fixed on the non-forming cavity of the die zone 3.
The non-forming cavity of die of the present utility model zone 3 is provided with mold insert connecting portion mounting groove 31, and mold insert connecting portion 42 is provided with installing hole 43, and mounting groove 31 bottoms in the non-forming cavity of die zone 3 and installing hole 43 corresponding positions are provided with screwed hole 32; Mold insert connecting portion 42 is anchored in the mounting groove 31 in the non-forming cavity of die zone 3 by the installing hole 43 that screw 5 passes mold insert connecting portion 42, mold insert forming cavity 41 can be anchored in the mold insert groove 21 in die forming cavity zone 2 accordingly.
Installing hole 43 on the mold insert connecting portion 42 of the present utility model is provided with the counterbore 44 that is used to take in screw head.
