There is complex structure in existing motorcar air conditioner shell cast mould, is not easy to the demoulding, the shortcoming that mold height is large.

The utility model content

The utility model provides a kind of squeeze casting mould of motorcar air conditioner housing, and the utility model has solved existing motorcar air conditioner shell cast mould and had complex structure, is not easy to the demoulding, the problem that mold height is large.

For addressing the above problem, the utility model adopts following technical scheme: the squeeze casting mould of motorcar air conditioner housing, comprise movable pressing board, moving platen, solid plate and cover half seat, solid plate is fixedly installed in above the cover half seat, moving platen is installed on the solid plate top, and movable pressing board is installed on the moving platen top;

Also comprise the taper pin side core-drawing mechanism, this mechanism is made of taper pin, slide block, intermediate plate and baffle plate, and intermediate plate and guide plate are installed between moving platen and the solid plate, and baffle plate is fixed in the guide plate two ends, and slide block is arranged in the groove below the intermediate plate; At moving platen and intermediate plate the hole of oblique perforation is arranged, taper pin is arranged in this hole, taper pin lower end connection sliding block;

Also comprise guiding mechanism, this mechanism comprises locking block, inserts, and is provided with backing plate and gripper shoe between movable pressing board and the moving platen, and four locking blocks are fixed on the gripper shoe; Insert and be embedded on the moving platen.

The utlity model has following advantage:: 1. mould structure is simple, is convenient to the demoulding; 2. be conducive to the pressure transmission; 3. be convenient to cast, exhaust and exert pressure; 4. can effectively reduce extrusion casint power; 5. can effectively reduce mold height, extrusion casint stroke, stripping stroke and knockout press, foundry goods can be vertically placed in the mould.

The specific embodiment

The below is described in detail the utility model with best embodiment.

As Figure 1-3, the squeeze casting mould of motorcar air conditioner housing comprises movable pressing board, moving platen, solid plate and cover half seat, and solid plate is fixedly installed in above the cover half seat, and moving platen is installed on the solid plate top, and movable pressing board is installed on the moving platen top;

Also comprise the taper pin side core-drawing mechanism, this mechanism is made of taper pin, slide block, intermediate plate and baffle plate, and intermediate plate and guide plate are installed between moving platen and the solid plate, and baffle plate is fixed in the guide plate two ends, and slide block is arranged in the groove below the intermediate plate; At moving platen and intermediate plate the hole of oblique perforation is arranged, taper pin is arranged in this hole, taper pin lower end connection sliding block; The effect of wedge block and postive stop baffle is to loose core action accurately and reliably in order to guarantee;

Also comprise guiding mechanism, this mechanism comprises locking block, inserts, and is provided with backing plate and gripper shoe between movable pressing board and the moving platen, and four locking blocks are fixed on the gripper shoe; Insert and be embedded on the moving platen.Move upward with moving platen during die sinking; The link plate double-screw bolt lays respectively at moving platen, intermediate plate and mould and pulls, and in order to realize two-time parting, shedding mechanism is comprised of push pedal, ejector pin retaining plate, push pedal and back-moving spring.Push rod resets under the effect of back-moving spring after foundry goods is released.

The course of work of the present utility model is: with link plate moving platen 5 and intermediate plate 26 are connected, fully upper cylinder drives the part release backhauls such as movable pressing board, cushion block, core after the pressurize, mould at first at A die joint somatotype, is broken the cast gate clout, realizes for the first time somatotype; Matched moulds is taken away the link plate that connects 5 and 26, solid plate 9 and intermediate plate 26 is connected again, again die sinking, intermediate plate then rests on top clamping plate one side, realizes for the second time somatotype (B die joint) thereby foundry goods moves upward with core, and slide block is followed a little pins and realized side core-pulling to two lateral movements simultaneously.Take out foundry goods and clout, sprayed coating enters next circulation.

It should be noted that at last: obviously, above-described embodiment only is for the utility model example clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And the apparent variation of being amplified out thus or change still are among the protection domain of the present utility model.
