Description

A kind of lithium ion battery Soft Roll rushes shell mold tool
Technical field
The present invention relates to lithium ion battery production moulds, rush shell mold tool more particularly to a kind of lithium ion battery Soft Roll.
Background technique
At present polymer Li-ion battery in process of production, if aluminum plastic film is cheated deep excessive (>=3.9mm), aluminum plastic film at The angle R position has the hidden danger of excessive tensile after type, so as to cause angle position aluminium layer residual quantity phenomenon not up to standard;Die springs are lacked then excessively Bolster is uneven to plastic-aluminum film pressure during punching press aluminum plastic film, and causing, which influences battery appearance etc. in aluminum plastic film corrugation, asks Topic, so must assure that bolster can accurately and uniformly compress aluminum plastic film, 4 sides can be with Uniform Tension, at present when cheating punching Since mould punching precision is not enough extremely difficult to require.
Summary of the invention
The purpose of the present invention is to the above problem, a kind of lithium ion battery Soft Roll is provided and rushes shell mold tool.
The technical scheme adopted by the invention is that: a kind of lithium ion battery Soft Roll rushes shell mold tool, comprising: cope plate, lower die Plate, cope plate are equipped with mold and punching head, mold and punching head pedestal, die springs, limit for height screw and pin, cope plate and lower template it Between be equipped with positioning and guiding mould, set that there are two pilot holes identical with lower template cavity dimension on guiding module, guiding hole site is under The die cavity position of mould is corresponding up and down;The upper surface of the mold and punching head is equipped with guide pad, and guide pad passes through mold and punching head pedestal It is fixedly connected with cope plate, guide pad is inserted into the pilot hole of guiding module from top to bottom and moves up and down in press work;It is described Four sides of guide pad be respectively equipped with vertical air discharge duct;Divide on the front side of the mold and punching head and the cope plate of rear side The identical die springs of two professional etiquette lattice are not set, and the spacing of adjacent die springs is less than the diameter of spring.
The mold and punching head is Teflon formed punch.
Two air discharge ducts are at least arranged in each side of the air discharge duct of the guiding module.
Beneficial effects of the present invention: it due to being equipped with positioning and guiding mould, stretches more uniform when aluminum plastic film can be made to form, mentions Aluminum plastic film final product quality is risen, and can significantly save debug time when remodeling, it is required when reducing commissioning device to scrap Plastic-aluminum film raw material, to save cost.
Detailed description of the invention
Fig. 1 is the stereoscopic schematic diagram that the one of embodiment upper and lower mould of the present invention is separately shown.
Fig. 2 is the schematic diagram that cope plate removes die springs, limit for height screw and pin.
Fig. 3 is the schematic diagram of mold and punching head.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiment is only a part of the embodiments of the present invention, instead of all the embodiments.Base Embodiment in the present invention, those of ordinary skill in the art are obtained all without making creative work Other embodiments shall fall within the protection scope of the present invention.
As shown in Figure 1 to Figure 3, the present invention includes: cope plate 1, lower template 3, and cope plate 1 is equipped with mold and punching head 11, mould Have formed punch pedestal 12, die springs 13, limit for height screw 14 and pin 15, positioning and guiding mould is equipped between cope plate 1 and lower template 3 2, it sets on guiding module there are two pilot hole 21 identical with cavity dimension, is oriented to hole site and 31 position of die cavity of lower template or more It is corresponding;The upper surface of the mold and punching head is equipped with guide pad 111, and guide pad connects by the way that mold and punching head pedestal and cope plate are fixed It connects, guide pad is inserted into from top to bottom in pilot hole in press work and guide pad horizontal direction is not shaken, at this time mold and punching head It is positioned with pilot hole inner wall precision-fit, mold and punching head plays the role of guiding, makes the gap of mold and punching head Yu type chamber both sides Higher precision is kept, four sides more uniform can stretch in aluminum plastic film forming process, promote aluminum plastic film final product quality.Institute Four sides are respectively equipped with two vertical air discharge ducts 1111 on the guide pad stated;As shown in Fig. 2, before the mold and punching head Side and rear side are respectively set the identical die springs of two professional etiquette lattice, and the spacing of adjacent die springs is less than the diameter of spring, and two The each position stress of aluminum plastic film is more evenly when row spring makes mould punching.Mold and punching head material is Teflon, i.e. polytetrafluoroethylene (PTFE). Teflon formed punch and pilot hole precision-fit, pilot hole play the guiding role, and are consistent mold and punching head with type chamber both sides gap, And mold and punching head and guiding hole wall guarantee smoothness come frictional force when reducing punch forming between Teflon formed punch and inner wall, To have the function that extend the Teflon formed punch service life.
When work, upper template pin passes through the pin hole 22 of positioning and guiding mould and the pin hole 32 of lower template,
Aluminum plastic film uniformly compresses between the pin hole of guiding module and the pin hole of lower template, and by cylinder, upper template is pushed, Teflon formed punch carries out punch forming to aluminum plastic film.It is connected with limit for height screw between upper template 1 and guiding module 2, uses limit for height spiral shell Silk can make two pieces of templates keeping parallelism in a non-operative state, and each spring stress is equal, extend spring life.
