Abstract
The utility model discloses a kind of punch retainer fast replacing structure, it comprises holder, fixed head, die cavity mold insert, adjusts pad, bolt; Described fixed head is fixed on holder, die cavity mold insert is nested with in the embedding piece groove of fixed head and is bolted on holder, between the embedding piece groove cell wall of die cavity mold insert two side and fixed head, there is gap, in this gap, be provided with one and adjust pad or polylith adjustment pad.Because the utility model is locked inverted hanging platform on fixed head die cavity mold insert on holder by bolt, and the pad direction both sides that mold insert need adjust that are placed in will be adjusted, when stamping-out cavity positions in need are adjusted die cavity mold insert, die cavity mold insert can be pulled down, in gap between the embedding piece groove cell wall of die cavity mold insert two side and fixed head, pad processing is adjusted in increase and decrease, thereby has saved a large amount of dismounting man-hours.
Description
Technical field
The utility model relates to a kind of cold-punching mold, particularly relates to a kind of punch retainer fast replacing structure.
Background technology
Along with lead frame structure develops to microminiature, encapsulation client is more and more higher to the dimension precision requirement of product.For the fluctuation that the external factors such as reply part processing precision and raw material size cause product size, a lot of moulds are all designed to adjustable structure in stamping-out key component (fixed head, stripper).As shown in Figure 1, early stage fixed head 1 ', mold insert 2 ' are all made extension mesa structure, and mold insert 2 ' is nested with in fixed head 1 ' in the mode of interference fit, and fixed head 1 ' is bolted on holder 3 '.This mould of commonly using, if will adjust position dimension in producing, adds and subtracts pad processing after fixed head 1 ' need being pulled down, and operates comparatively loaded down with trivial details.
Utility model content
The purpose of this utility model is to provide a kind of and changes more simply, punch retainer fast replacing structure efficiently.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of punch retainer fast replacing structure, and it comprises holder, fixed head, die cavity mold insert, adjusts pad, bolt; Described fixed head is fixed on holder, die cavity mold insert is nested with in the embedding piece groove of fixed head and is bolted on holder, between the embedding piece groove cell wall of die cavity mold insert two side and fixed head, there is gap, in this gap, be provided with one and adjust pad or polylith adjustment pad.
Described die cavity mold insert middle part is provided with die cavity, and its one end is provided with hanging platform, and the hanging platform of die cavity mold insert is inverted and is fixed on holder.
Adopt after such scheme, because the utility model is locked inverted hanging platform on fixed head die cavity mold insert on holder by bolt, and the pad direction both sides that mold insert need adjust that are placed in will be adjusted, when stamping-out cavity positions in need are adjusted die cavity mold insert, die cavity mold insert can be pulled down, in gap between the embedding piece groove cell wall of die cavity mold insert two side and fixed head, pad processing is adjusted in increase and decrease, thereby has saved a large amount of dismounting man-hours.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Brief description of the drawings
Fig. 1 commonly uses punch retainer structural representation;
Fig. 2 is schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 2, the utility model is a kind of punch retainer fast replacing structure, and it comprises holder 1, fixed head 2, die cavity mold insert 3, adjusts pad 4, bolt 5.
Described fixed head 2 is fixed on holder 1.Described die cavity mold insert 3 middle parts are provided with die cavity 31, its one end is provided with hanging platform 32, die cavity mold insert 3 is nested with in the embedding piece groove 21 of fixed head 2 and the hanging platform 32 of die cavity mold insert 3 is inversion shape, die cavity mold insert 3 is fixed on holder 1 by bolt 5, need to there is gap between the adjustment two side of direction and embedding piece groove 21 cell walls of fixed head 2 at die cavity mold insert 3, in this gap, be provided with one and adjust pad 4 or polylith adjustment pad 4.
Method of adjustment of the present utility model:
When stamping-out cavity positions in need are adjusted die cavity mold insert 3, die cavity mold insert 3 can be pulled down, in gap between embedding piece groove 21 cell walls of die cavity mold insert 3 two sides and fixed head 2, pad 4 is adjusted in increase and decrease, and the adjustment pad 4 of increase and decrease can adopt the pad of varying number or different-thickness.
Emphasis of the present utility model is just: at die cavity mold insert and fixed head embedding piece groove, adjustment pad is set.
The above, it is only the utility model preferred embodiment, therefore can not limit the scope that the utility model is implemented with this, the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
