Abstract
The utility model discloses an injection mold for tunnel slide blocks. The injection mold comprises a mold core and a mold cavity formed in the mold core, wherein a tunnel slide hole corresponding to the mold cavity is formed in the mold core, penetrates the mold cavity and runs through the mold core; the tunnel slide blocks are arranged in the tunnel slide hole located in one side of the mold cavity; and inserts corresponding to the tunnel slide blocks are arranged in the tunnel slide hole located in the other side of the mold cavity. The tunnel slide hole is set to be a through hole, the inserts are added to the other side, corresponding to the tunnel slide blocks, of the tunnel slide hole, the through tunnel slide hole is processed by wire cut slow-feeding, the processing time is short, the precision is high, and the processing efficiency and precision of the injection mold are improved effectively.
Description
Technical field
The utility model relates to a kind of injection mold, particularly a kind of injection mold with tunnel line position piece.
Background technology
For the plasthetics with the feature such as lateral aperture, side buckle, cannot be normally after injection mo(u)lding when ejecting the direction demoulding, just must be first with loosing core the demoulding from the side of type mechanism for features such as lateral aperture or side fixture blocks, and then eject, and the core-pulling mechanism adopting is generally slide block mechanism, pitched roof mechanism etc.Common slide block can be from the direct dismounting of the die joint of mould, when the structure of plasthetics more special, use common slipper block loose core, by the forming part of die joint can not the demoulding time, just need to use tunnel slipper block loose core, as shown in Figure 1, to in product 14, cannot make separately slide block from the position that ejects the normal demoulding of direction, instead of open-minded toward die joint, such slide block slot in die 11 just as a tunnel, its advantage is that volume is little, lightweight, the area of contact goods is little, when injection moulding, pressure-bearing is little, life-span is long, the required power of loosing core is little, but 12, the line position hole, tunnel of this kind of structure is positioned at the die 11 of die cavity one side, therefore in, can only process by spark machine, length consuming time, low precision, greatly increase the precision of mold cycle and reduction mould.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of tunnel line position piece injection mold, to obtain the more easily die of the tunnel line position pore structure of processing, improves production efficiency and the service precision of injection mold.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of tunnel line position piece injection mold, comprise die and be positioned at the die cavity of described die, on described die, offer the line position hole, tunnel of corresponding described die cavity, line position hole, described tunnel is through described die cavity and run through described die, the line position hole, described tunnel that is positioned at described die cavity one side is provided with tunnel line position piece, and the line position hole, described tunnel that is positioned at described die cavity opposite side is provided with the mold insert of corresponding described tunnel line position piece.
Wherein, the described mold insert one end that is positioned at described die outer wall side one end is provided with boss, and the corresponding described boss of described tunnel line position piece place is provided with draw-in groove, and described boss engages mutually with described draw-in groove.
Pass through technique scheme, the tunnel line position piece injection mold that the utility model provides, it is set to through hole by line position hole, tunnel, line position hole, the tunnel another side that tunnel line position piece is set in correspondence increases mold insert, slow wire feeding processing is cut by line in the line position hole, tunnel of this perforation, comparing non-through line position hole, tunnel needs the mach mode of spark, and this line cuts that slow wire feeding process time is short, precision is high, has effectively improved working (machining) efficiency and the precision of injection mold.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
With reference to figure 2 and 3, the tunnel line position piece injection mold that the utility model provides, comprise die 11 and be positioned at the die cavity of die 11, on die 11, offer the line position hole, tunnel 12 of corresponding die cavity, line position hole, tunnel 12 is through die cavity and run through die 11, the line position hole, tunnel 12 that is positioned at die cavity one side is provided with the tunnel line position piece 13 of corresponding product 14, and the line position hole, tunnel 12 that is positioned at die cavity opposite side is provided with the mold insert 15 of corresponding tunnel line position piece 13.
Wherein, mold insert 15 one end that are positioned at die 11 outer wall side one end are provided with boss 21, and the corresponding boss of tunnel line position piece 13 21 places are provided with draw-in groove, and boss 21 engages mutually with draw-in groove.
The tunnel line position piece injection mold that the utility model provides, it is by being set to through hole by line position hole, tunnel 12, line position hole, tunnel 12 another sides that tunnel line position piece 13 is set in correspondence increase mold insert 15, slow wire feeding processing is cut by line in the line position hole 12, tunnel of this perforation, compare non-through line position hole, tunnel and need the mach mode of spark, this line cuts that slow wire feeding process time is short, precision is high, has effectively improved working (machining) efficiency and the precision of injection mold.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.To be apparent for those skilled in the art to the multiple amendment of above-described embodiment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
