Abstract
The utility model discloses a double-stroke direction battery sealing die structure, include: the mould comprises an upper mould and a lower mould which are matched with each other, wherein a punch is arranged inside a mould cavity of the upper mould, a punch head of the punch head faces downwards, an ejector rod is arranged in the mould cavity of the lower mould, a side ring of the ejector rod is provided with an insert, the top end of the ejector rod is provided with a forming cavity for forming a battery, the lower end of the ejector rod is narrowed and extends downwards, a small spring is nested at the lower end of the ejector rod, a large spring is nested at the lower half section of the small spring, the small spring can avoid overlarge spring force feedback during extrusion and pop out the battery in the forming cavity, the large spring is extruded during continuous compression and is formed, and the large spring guarantees the die parting force during die parting, so that the production quality of the battery necking is effectively guaranteed, and the die opening force is guaranteed.
Description
Technical Field
The utility model belongs to the technical field of the mould and specifically relates to a two stroke direction battery sealing die structure is related to.
Background
In the stamping forming of battery throat, present shaping is single stroke stamping die structure mostly, all has a spring on such structure ejector pin, when compound die production, when this spring has great spring force for big spring, great spring feedback power can push up the ejector pin upwards for the battery with the mold insert condition of off tracking appears easily, when the spring is less spring feedback power spring, the power of spring is not enough to support the dynamics that the mould divides the mould, thereby influences the die sinking.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an it is not enough to overcome above-mentioned condition, aims at providing the technical scheme that can solve above-mentioned problem.
A kind of double-stroke direction battery seals the mould structure, including: the battery forming die comprises an upper die and a lower die which are matched with each other, wherein a punch is arranged inside a die cavity of the upper die, a punch head of the punch is downward, an ejector rod is arranged in the die cavity of the lower die, an insert is arranged on a side ring of the ejector rod, a forming cavity for forming a battery is arranged at the top end of the ejector rod, the lower end of the ejector rod is narrowed and extends downward, a small spring is nested at the lower end of the ejector rod, and a large spring is nested at the lower half section of.
As a further aspect of the present invention: the insert is an annular seal insert.
Compared with the prior art, the beneficial effects of the utility model are that: the small spring can avoid too large spring force feedback during extrusion and pop up the battery in the forming cavity, the large spring is extruded during continuous compression to form, and the large spring guarantees the die parting force during die parting, so that the production quality of battery necking is effectively guaranteed, and the die opening force is guaranteed while the production precision and concentricity are guaranteed through the double-stroke spring structure.
Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a sectional view of the internal structure of the present invention.
In the figure: 1. the die comprises an upper die, a lower die, 11, a punch, 12, a forming cavity, 13, a mandril, 14, a small spring, 15, a large spring, 16 and an insert.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
A kind of double-stroke direction battery seals the mould structure, including: the battery forming die comprises an upper die 1 and a lower die 2 which are matched with each other, wherein a punch 11 is arranged inside a die cavity of the upper die 1, a punch head of the punch 11 faces downwards, an ejector rod 13 is arranged in the die cavity of the lower die 2, a side ring of the ejector rod 13 is provided with an insert 16, a forming cavity 12 for forming a battery is arranged at the top end of the ejector rod 13, the lower end of the ejector rod 13 is narrowed and extends downwards, a small spring 14 is nested at the lower end of the ejector rod 13, and a large spring 15 is nested at the lower half section of.
Insert 16 is an annular seal insert 16.
The utility model discloses a theory of operation is: when the battery is produced and assembled, the battery is placed in the forming cavity 12, the upper die 1 and the lower die 2 are assembled, the upper die 1 is extruded downwards by the stamping force of stamping equipment, so that the punch 11 is pushed to stamp downwards, when the ejector rod 13 bears the stamping force, the ejector rod 13 extrudes the spring downwards, the ejector rod 13 extrudes the small spring 14 firstly, the battery is corrected concentrically by the insert 16, the phenomenon that the spring force is fed back too much to eject the battery in the forming cavity 12 when the extrusion is avoided, the large spring 15 is extruded when the compression is continued, the forming is carried out, and the large spring 15 ensures the die parting force when the die is parted.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
