Abstract
The utility model provides a plunger chip structure for a mould pre-punching hole. The plunger chip is composed of an outer lining, an upper plunger chip, an inner lining and a lower plunger chip, the inner lining is sleeved at the lower end of the outer lining in an embedded mode, the upper plunger chip is fixed inside the outer lining and arranged at the upper end of a lower lining, and the lower plunger chip is fixed inside the inner lining. The plunger chip structure for the mould pre-punching hole has the advantages that a plunger chip structure is designed to be in a two-layer lining structure, and therefore the phenomenon that the plunger chip is broken in the process of punching due to small diameter is avoided, and durability of the plunger chip is improved.
Description
Technical field
The utility model relates to a kind of punch structure for the mould pre-punched hole.
Background technology
The existing punch structure that is used for the mould pre-punched hole is comprised of up big and down small red needle 1 and DM spring 2 as shown in Figure 1.
The drift of this spring structure at pre-punched hole hour, drift easily fractures, thereby causes repairing a die often, product quality can not be guaranteed.
The utility model content
The utility model is to overcome the above-mentioned existing shortcoming that is used for the punch structure of mould pre-punched hole, and a kind of punch structure that is difficult for losing is provided.
The utility model realizes that the technical scheme that goal of the invention adopts is, a kind of punch structure for the mould pre-punched hole, described drift is comprised of external bushing, upper punch, neck bush and low punch, described neck bush is nested in the lower end of described external bushing, described upper punch is fixed in described external bushing and is positioned at the upper end of described lower lining, and described low punch is fixed in described neck bush.
Preferably, the diameter of described upper punch equals the external diameter of described neck bush.
Preferably, described low punch is nail shape structure.
The beneficial effects of the utility model are: by punch structure being designed to by the two-layered liner structure, can prevent that drift from being fractureed in the punching process because diameter is less, improved the durability of drift.
Description of drawings
Fig. 1, existing punch structure figure for the mould pre-punched hole.
Fig. 2, the punch structure figure that is used for the mould pre-punched hole of embodiment.
The specific embodiment
A kind of punch structure for the mould pre-punched hole, its structure chart is referring to accompanying drawing 2, formed by external bushing 3, upper punch 4, neck bush 5 and low punch 6, neck bush 5 is nested in the lower end of external bushing 3, upper punch 4 is fixed in external bushing 3 and is positioned at the upper end of neck bush 5, the diameter of upper punch 4 equals the external diameter of neck bush 5, and low punch 6 is nail shape structure, and low punch 6 is fixed in neck bush 5.
The punch structure that is used for the mould pre-punched hole of the present embodiment can prevent that by punch structure being designed to by the two-layered liner structure drift from being fractureed in the punching process because diameter is less, improved the durability of drift.
It should be noted that at last: above embodiment is only in order to illustrate the utility model and the described technical scheme of unrestricted the utility model; Although therefore this specification has been described in detail the utility model with reference to each above-mentioned embodiment, it will be understood by those of skill in the art that still and can modify or be equal to replacement the utility model; And all do not break away from technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in claim scope of the present utility model.
Claims (3)
1. punch structure that is used for the mould pre-punched hole, it is characterized in that: described drift is comprised of external bushing, upper punch, neck bush and low punch, described neck bush is nested in the lower end of described external bushing, described upper punch is fixed in described external bushing and is positioned at the upper end of described lower lining, and described low punch is fixed in described neck bush.
2. the punch structure for the mould pre-punched hole according to claim 1, it is characterized in that: the diameter of described upper punch equals the external diameter of described neck bush.
