Description

A kind of New energy automobile motor end cover die

Technical field

The utility model belongs to technical field of new energy, specifically designs a kind of New energy automobile motor end cover die.

Background technology

Electric motor of automobile end cap is since shape is irregular, and intensity requirement is not high, therefore is used in auto-parts production One of spare and accessory parts formed are cast, for other more complicated cast articles, since automobile end cover structure is relatively easy, Therefore mold design is also relatively easy, mostly using centre into molten aluminum, mould structure, although however, end cover structure is more simple It is single, but ending cover thickness is smaller, this causes casting cavity passage small, so that flow rate of aluminium liquid reduces, heat in flow process Loss is big, and end cap shaping is slow, and casting quality is undesirable.

Utility model content

In view of the foregoing deficiencies of prior art, the purpose of this utility model is to provide a kind of New energy automobile motor End cover die, has the characteristics of cast molding is fast, and casting quality is good.

In order to achieve the above objects and other related objects, the utility model provides a kind of New energy automobile motor end cap mould Tool, a kind of New energy automobile motor end cover die, including upper die and lower die, the upper mold include upper mold seat, upper die head and upper mold Plate, the lower die include lower template and lower mold core, and sand core is equipped between cope plate and lower mold core, and the upper mold and the lower die are closed During mould, required casting cavity is surrounded between the cope plate, lower mold core and sand core, two are symmetrically offered in the lower template Connect the cast gate of casting type cavity edge.

The beneficial effect of the use of the new type using the above scheme is：Using the structure design of both sides double cast gate so that aluminium Liquid energy reaches Fast Filling casting cavity, and shaping is quick, and casting quality is good.

Further, centered on the cope plate perforate rotary structure, the cope plate core is to away from cavity One end protrusion of side.

Further, the lower mold core is circular ring structure, and the lower mold core is fixed on die holder and is coaxially set with cope plate Put.Further, it is provided with sand core in the cope plate and the circle center hole of lower mold core.

Further, the sand core is up-small and down-big rotary structure, and the sand core lower end outside is equipped with round flange, institute Flange is stated to be fixed between lower mold core and die holder.

Further, the sand core flange top outer sheath is equipped with steel bushing.

Further, mold pushing mechanism is equipped between the upper mold seat and upper die head.

Further, the cast gate is externally provided with sprue cup.

Further, light weight hole is offered on the upper mold seat.

In conclusion utility model using the above scheme, the structure using the double stalk mouths of low pressure casting into aluminium water, by It is very thin in end cap product wall thickness, traditional middle single port is changed to both ends twoport into aluminium into aluminium, shaping speed is accelerated, solves Product wall thickness is owed the problem of thin, and steel bushing is preset in mould so that steel bushing and product are integrally formed.

Embodiment

Illustrate the embodiment of the utility model by particular specific embodiment below, those skilled in the art can be by this Content disclosed by specification understands other advantages and effect of the utility model easily.

It should be clear that cited such as " on ", " under " in this specification, "left", "right", the term of " centre " and " one ", also Only understanding for ease of narration, and be not used to limit the enforceable scope of the utility model, its relativeness is altered or modified, In the case where changing technology contents without essence, when being also considered as the enforceable category of the utility model.

As shown in Figure 1 to Figure 3, a kind of new energy motor end cover mould, including upper die and lower die, upper mold include upper mold seat 1, Upper die head 2 and cope plate 3, lower die include lower template 4 and lower mold core 5, sand core 6, upper mold are equipped between cope plate 3 and lower mold core 5 When being molded with lower die, required casting cavity 7 is surrounded between cope plate 3, lower mold core 5 and sand core 6, is symmetrically opened up in lower template 4 There is the cast gate 41 at two 7 edges of connection casting cavity.

Specifically, 1 lower end of upper mold seat is fixedly connected by middle upper die head 2 with the cope plate 3 of lower section, upper mold seat 1 wraps Rectangular flat and the rectangular side panels positioned at rectangular flat lower end both sides are included, light weight hole 11 is offered on side plate, upper mold seat lower end connects It is connected to upper die head 2, the rectangular flat structure of perforate, 2 lower face center of upper die head are connected with cope plate 3 centered on upper die head 2, on The rotary structure of perforate centered on template 3,3 center hole of cope plate close on part and are protruded to upside.

Specifically, 4 upper surface center of lower template is connected with lower mold core 5, lower mold core 5 is circular ring structure, lower mold core 5 and upper mold Plate 3 is coaxial, and 5 diameter of bore size of lower mold core is more than 3 center hole diameter dimension of cope plate, lower mold core 5 and 3 endoporus of cope plate it Between be equipped with the sand core 6 of a up-small and down-big rotary structure, 6 lower end of sand core is equipped with flange, which is nested in lower mold core 5 with Between die holder 4,6 lower outside of sand core is arranged with annular steel bushing 61.

Specifically, 4 lower face of die holder offers two cast gates 41 connected with casting cavity 7, it is arranged with outside cast gate 41 Sprue cup 42, cast gate 41 are connected with 7 both sides of casting cavity respectively.
