Abstract
The utility model discloses a kind of offhand device for injection-molded item mounting hole, comprise a pliers, on two jaws of described pliers, be installed with respectively die and punch, described die is provided with the poroid groove of kidney-shaped, and punch is provided with the projection matching with described groove.Between projection location by punch and groove and projection, shear action cuts off the plastic cement at mounting hole place, reaches quickly and easily needing the mounting hole of following process moulding to carry out moulding on moulding, improves shaping efficiency, reduces manufacturing expense.
Description
technical field
The utility model relates to plastic products processing technique field, is specifically related to a kind of offhand device for injection-molded item mounting hole.
Background technology
Injection-molded item, because of the needs with other accessory assemblings, needs a lot of kidney-shapeds of moulding or circular screw hole, through hole in its periphery, inside.Generally under normal circumstances, these holes are all to take mould disposal molding, but on specific position, mould is cannot be to its straight forming, as be positioned at runner most end stomidium and exist weld mark position intensity cannot meet assembling, also have two kinds of the porose and atresias of product needed etc. and above state, following process moulding all need to be carried out to it in these holes after product injection mo(u)lding.Wherein less circular hole takes drill bit directly to hole conventionally, and high due to difficult location, its position, assembly precision requirement for mounting hole, needs to take frock clamp to position, and then carrys out punching with punch press.Cumbersome for the hole operation that is positioned at edge like this, and Meteorological is large, efficiency is low.
utility model contentfor above-mentioned problems of the prior art, the purpose of this utility model is to propose a kind of offhand device for injection-molded item mounting hole, and it not only invests little, easy to use, also can when finishing is produced in injection moulding, complete together.
The technical scheme that the utility model is taked in order to realize its object:
An offhand device for injection-molded item mounting hole, comprises a pliers, on two jaws of described pliers, is installed with respectively die and punch, and described die is provided with the poroid groove of kidney-shaped, and punch is provided with the projection matching with described groove.
Preferred version is that described pliers is ratchet-type Press Plier.
More preferably scheme is, the inner side of described die and punch offers respectively draw-in groove, and die and punch are fastened on jaw and are bolted by draw-in groove symmetry respectively.
In shaped device of the present utility model, die, punch be according to requirements such as the shape of the mounting hole of wanted moulding, wall thickness, by metal wire cutting processing, and joins mould and be made.Ratchet-type Press Plier is existing instrument on market, on the die that is positioned at groove one side, offer the draw-in groove matching for the mouth with ratchet-type Press Plier, equally be positioned at projection one side punch on open draw-in groove, and the mouth of ratchet-type Press Plier is processed, to coordinate draw-in groove on die, punch; Then die, punch symmetry are arranged on to jaw and are fixed with bolt.
After the moulding that need to process is produced, utilize projection on punch to locate the position that will offer mounting hole of moulding, then the handle that grasps ratchet-type Press Plier firmly clamps, utilize shear action between groove on die and the projection on punch that the plastic cement at mounting hole place is cut off, reach the object of moulding mounting hole, unclamp after the handle of ratchet-type Press Plier, can again to the mounting hole of other positions, carry out forming operation.
This device manufacturing expense is low, volume is little, and can improve shaping efficiency quickly and easily to needing the mounting hole of following process moulding to carry out moulding on moulding, reduces manufacturing expense.
In addition, according to need of production, the groove on die and the projection shape on punch can be designed to circle, square etc., thereby reach the requirement in the hole that forms various shapes.And in the time of can carrying out moulding to difform hole, as long as be replaced with corresponding die and punch, easy and simple to handle.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Fig. 1 is the utility model structural representation;
Fig. 2 is cavity die structure schematic diagram of the present utility model;
Fig. 3 is the right view of Fig. 2;
Fig. 4 is punch structure schematic diagram of the present utility model;
Fig. 5 is the left view of Fig. 4.
In figure: 1-ratchet-type Press Plier, 2-jaw, 3-punch, 4-die, 5-bolt, 6-draw-in groove, 7-groove, 8-projection.
The specific embodiment
As shown in Figure 1, a kind of offhand device for injection-molded item mounting hole, comprise ratchet-type Press Plier 1, on two jaws 2 of described ratchet-type Press Plier 1, be installed with respectively die 4 and punch 3, described die 4 is provided with the poroid groove 7 of kidney-shaped, and punch 3 is provided with the projection 8 matching with described groove.As shown in Figure 2,3, the inner side of die 4 and punch 3 offers respectively draw-in groove 6, and die 4 and punch 3 are fastened on jaw 2 and by bolt 5 and are fixed by draw-in groove 6 symmetries respectively.
Add man-hour, utilize projection 8 on punch 3 to locate the position that will offer mounting hole of moulding, then the handle that grasps ratchet-type Press Plier 1 firmly clamps, utilize shear action between groove 7 on die 4 and the projection 8 on punch 3 that the plastic cement at mounting hole place is cut off, reach the object of moulding mounting hole.
Above embodiment is not limited only to protection domain of the present utility model, all based on basic thought of the present utility model, modify or change all belong to protection domain of the present utility model.
