Description
Technical field
The utility model belongs to the technical field of moulding machine, specifically relates to a kind of mould emptier of moulding machine.
Background technology
At present, the mould emptier of moulding machine comprises demoulding pin, die sinking crossbeam, two cylinders, guide pin bushings and the guide pillar matching with this guide pin bushing.Wherein, die sinking crossbeam has two, is symmetrical mode setting and is fixed on the body both sides of moulding machine.Specifically, die sinking crossbeam is fixed on guide pin bushing, and guide pin bushing is enclosed within on guide pillar, and guide pillar is fixed on body by guide pillar support, and demoulding pin is arranged on die sinking crossbeam.Each die sinking crossbeam is promoted by a cylinder, and die sinking crossbeam is moved up and down.Be understandable that, two die sinking crossbeams of this moulding machine are promoted by two separate cylinders respectively, and therefore die sinking crossbeam easily occurs that in reciprocating motion process motion is asynchronous.
Summary of the invention
The purpose of this utility model is to provide a kind of mould emptier of moulding machine, and it can make the die sinking crossbeam of body both sides be synchronized with the movement.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of mould emptier of moulding machine, comprise two die sinking crossbeams of the both sides that are positioned at body, die sinking crossbeam is fixedly connected with guide pin bushing, guide pin bushing is enclosed within on guide pillar, and guide pillar is fixedly connected with body, on described die sinking crossbeam, is fixed with demoulding pin, synchronizing shaft is arranged on body by bearing block, and synchronizing shaft is rotatable with respect to bearing block; The two ends of synchronizing shaft are all connected by front arm, connecting rod and the die sinking crossbeam that is positioned at body one side, and described front arm is fixedly connected with described synchronizing shaft, and described front arm and described connecting rod are hinged, and described connecting rod and described die sinking crossbeam are hinged; Rear arm is fixedly connected with synchronizing shaft, and the output of linear reciprocating mechanism swings rear arm.
On the basis of such scheme and as the preferred version of such scheme: described linear reciprocating mechanism is hinged on body, and output and the rear arm of described linear reciprocating mechanism are hinged.
On the basis of such scheme and as the preferred version of such scheme: described linear reciprocating mechanism is fixed on body, and the output of linear reciprocating mechanism is pressed on rear arm and the output of linear reciprocating mechanism can slide on rear arm.
On the basis of such scheme and as the preferred version of such scheme: described linear reciprocating mechanism is cylinder.
The utility model compared to existing technology outstanding and useful technique effect is:
1, mould emptier of the present utility model; the transmission mechanism consisting of two route front arms and connecting rod same synchronizing shaft drives two die sinking crossbeams; and this synchronizing shaft is controlled rotation by same cylinder, two synchronisms that die sinking crossbeam moves up and down are ensured.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the side view of Fig. 1
Detailed description of the invention
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1;
The mould emptier of the moulding machine that embodiment mono-, the present embodiment provide has two die sinking crossbeams 2, and it is positioned at the both sides of body 1.Die sinking crossbeam also can be called the up and down support of the demoulding.Die sinking crossbeam 2 is fixedly connected with guide pin bushing 3.Guide pin bushing 3 is enclosed within on guide pillar 4, and guide pin bushing 3 can slide along guide pillar 4.Guide pillar 4 is fixedly connected with body 1, and in the present embodiment, guide pillar 4 is arranged on body 1 by guide pillar support 5.On described die sinking crossbeam 2, be fixed with demoulding pin 6, this demoulding pin is for being connected with the patrix of mould.In the time of work, on demoulding pin, move, patrix is opened.Synchronizing shaft 7 is arranged on body 1 by bearing block 8, and synchronizing shaft 7 is rotatable with respect to bearing block 8.The two ends of synchronizing shaft 7 are respectively connected by front arm 9, connecting rod 10 and the die sinking crossbeam 2 that is positioned at body one side, specifically, the transmission mechanism that all has front arm 9 and connecting rod 10 to form in the both sides of body 1, one transmission mechanism and drive one die sinking crossbeam 2, can synchronously drive at the die sinking crossbeam 2 of body 1 both sides synchronizing shaft 7 and work.Move back and forth in the given direction of guide pillar by making that the synchronizing shaft of reciprocating rotation can be realized to die sinking crossbeam by front arm and connecting rod, front arm 9 is fixedly connected with described synchronizing shaft 7, described front arm 9 is hinged with described connecting rod 10, and described connecting rod 10 is hinged with described die sinking crossbeam 2.The housing of cylinder 11 is installed in rotation on body 1, and the output of cylinder 11 and rear arm 12 are hinged, and rear arm 12 is fixedly connected with synchronizing shaft 7.Certainly, cylinder also can adopt other structure.When the mould emptier of this moulding machine is worked, by utilizing cylinder and rear arm structure to make synchronizing shaft reciprocating rotation, relend the structure that helps front arm, connecting rod, guide pin bushing and guide pillar, the rotation of synchronizing shaft is converted into pumping of die sinking crossbeam.As can be seen here, being driven by same cylinder of the die sinking crossbeam of body both sides, therefore pumping of die sinking crossbeam is synchronous.In the present embodiment, cylinder also can replace with other linear reciprocating mechanism.Such as oil cylinder, cam mechanism etc.
Mould emptier in the mould emptier of the moulding machine that embodiment bis-, the present embodiment provide and embodiment mono-is similar, its two only distinct on the mounting structure of cylinder.In the present embodiment, the housing of cylinder is fixed on body, and the output of cylinder top is pressed on rear arm, and the output of cylinder on rear arm slidably.
Above-described embodiment is only preferred embodiment of the present utility model, not limits according to this protection domain of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, within all should being covered by protection domain of the present utility model.
