Casting mould.
Background technology
New energy automobile motor shell is structure critically important in automobile engine using new energy resources, because new energy car battery continues
The limitation of boat, to mitigate the weight of part as much as possible, existing New energy automobile motor shell is mostly using fuselage and end cap point
Do not process, then assembling coordinates, and such design not only causes motor casing processed complex, and most important such mechanism causes most
Whole motor casing quality is larger.
The content of the invention
In view of the above the shortcomings that prior art, it is an object of the invention to provide a kind of new-energy automobile with end cap
Motor casing low pressure casting die, the fuselage of motor casing and end cap integrally casting shaping can be simplified the production of motor casing
Process, while mitigate the weight of motor casing.
In order to achieve the above objects and other related objects, it is low to provide a kind of New energy automobile motor shell with end cap by the present invention
Casting mould, including upper mould, side form group and lower mould, the upper mould is pressed to include upper bolster, upper die head and upper mold core, the lower mould bag
Die shoe and lower mold core are included, the upper mold core is stretched into the cavity that side form group surrounds, and bottom envelope is surrounded with side form group and lower mold core
Close the open tubular in end and pour die cavity, the side form group in the vertical direction is made up of the polylith matrix being laminated, adjacent two layers
Reinforcement is formed between on the inside of matrix and pours chamber.
Beneficial effect using the invention of such scheme is that the maximum side form of volume is divided into the overlapping diaphragm group of polylith
Into both having simplified side form manufacture difficulty, and can solves the problems, such as the exhaust problem of large volume casting.
Further, there is exhaust clearance between matrix described in adjacent two layers.
Further, the side form is made up of side form more than two, and every group of side form is configured with side form backboard and promotes side form to move
Dynamic drive mechanism.
Further, the side form both sides are provided with side form positioning seat, the side form backboard be located at adjacent two side forms positioning seat it
Between.
Further, every group of side form includes multilayer matrix, and matrix is integral by the bolt connection vertically worn described in multilayer.
Further, it is provided with cavity inside the side form.
Further, the upper mold core lower end is provided with spreader, and the position that the lower mold core corresponds to spreader is provided with
Cast gate.
Further, the spreader, which stands upside down, is arranged on lower mold core lower end, and to be located at pouring for lower mold core intraoral for conehead.
Further, guiding mechanism and lubricating structure are provided between the side form backboard and die shoe.
Further, the cast gate is externally connected with sprue cup, and mold pushing mechanism is provided between the upper bolster and upper die head.
In summary, using the invention of such scheme, because reinforcement is very thin, it is easy to asking for misrun occur
Topic, by the way of the superposition of polylith diaphragm, the gas in forming process can be quickly excluded, allow aluminium liquid smoothly to fill up reinforcement
Muscle, casing integrated design, the production technology of motor casing is simplified, adds the tightness of product, end cap and casing are integrally cast
Making reduces the weight of motor casing, positioning and guiding mechanism between side form, can effectively control open-close module precision.
