Abstract
The invention discloses a lithium-battery mold and a low-pressure injection molding method. The lithium-battery mold mainly comprises a front mold, a rear mold, an ejection system, a feed gate and a runner, wherein two mold cavities are respectively arranged in the front mold and the rear mold; the ejection mechanism is arranged in the mold cavity of the rear mold; the front end of the die cavity in the rear mold is respectively provided with a slide cavity and a slider; the front part of the die cavity in the front mold is provided with a buckle table which can be buckled on the outer wall of the slider; and the middle part of the front mold and the rear mold is provided with the feed gate and the runner. The low-pressure injection molding method comprises the following steps: sheathing an ABS engineering plastic molded part on the lithium battery and the protective plate connecting component, and putting into the mold cavity of the rear mold; closing the mold, injecting plastics, and injecting a resin material into the gaps among the components in the mold cavity; and opening the mold. The invention has the advantages of simple structure and convenient use, and can enhance the hardness and the smoothness of the battery surface as well as the battery capacity.
Description
Technical field
The present invention relates to the injection mold of cellular li-ion battery, refer more particularly to a kind of lithium battery low-pressure injection molding mould and low-pressure injection molding method.
Background technology
The preparation method of cellular li-ion battery is at present; in mould, battery and circuit protection plate are put into the directly low injected plastics material direct forming of employing of back; its weak point is: it is not enough to be prone to outward appearance hardness; the battery surface flatness is not good; simultaneously owing to be subjected to the injection pressure effect; the smaller volume of battery own causes battery capacity to reduce.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point of the prior art and provide a kind of simple in structure, the convenient use, and can make battery surface hardness height, flatness is good, battery capacity improves a kind of novel lithium battery low-pressure injection molding mould and low-pressure injection molding method.
The present invention realizes in the following way: the present invention mainly includes: mould, injection mold ejecting mechanism, injection mold advance cast gate and runner behind injection mold front mould, the injection mold; Wherein: behind injection mold front mould and injection mold, be respectively equipped with two die cavitys in the mould; Behind injection mold, be respectively equipped with an injection mold ejecting mechanism in the die cavity of mould; The die cavity front end of mould is respectively equipped with a sliding chamber behind injection mold, is respectively equipped with a slide block in it, is provided with chute in the both sides in sliding chamber, and described slide block is contained in also in sliding the chamber in can slippage in the chute in this cunning chamber; The corresponding front portion at injection mold front mould die cavity is respectively equipped with a button platform, and when mould behind injection mold front mould and the injection mold fastened, this button platform can be buckled in the outer wall of slide block, makes slide block to skid off in the sliding chamber of mould behind the injection mold; The mould pars intermedia is provided with injection mold and advances cast gate and runner behind injection mold front mould and injection mold, and described runner links to each other with die cavity respectively.
Low-pressure injection molding method: process mould behind injection mold front mould and the injection mold earlier; after before injection moulding, earlier lithium ion battery and baffle coupling assembling being put ABS engineering plastics drip molding; put into mould die cavity behind the injection mold; with front mould and back mould closure, advance cast gate and runner injection plastic cement by injection mold then.Resin material is injected in the gap of each assembly in the die cavity, play filling, bonding, fixation.Die sinking is then taken out two batteries by mold liftout attachment.
In sum, the present invention is simple in structure, and convenient the use adopted ABS engineering material elder generation shaping shell, again low pressure material injected each component intermediate gaps position of battery, reach flat appearance, hardness good, be difficult for damaging.
