Preferably, the centre of four sides is equipped with a clamping apparatus.
Preferably, groups of springs comprises two springs.
Preferably, the contact-making surface group of locked mode button one and locked mode button two includes horizontal plane and vertical plane.
Through technique scheme, the injection machine that the utility model provided is not only through the clamping apparatus of installation site symmetry on template, makes the stressed relatively balance of template, avoided template deformation, to improve machining accuracy; And through locked mode button two and the locked mode button one incompatible increase clamp force that matches, to improve machining accuracy; Also rise or descend through controlling latch segment with spring when matched moulds and the die sinking, with the mutual frictional force of effective minimizing locked mode button two and locked mode button one, so this injection machine has the machining accuracy height, and the advantage grown of life-span.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Front view when Fig. 1 is the disclosed a kind of injection moulding machine mould open of the utility model embodiment;
Fig. 2 is the three-dimensional assembly diagram of the disclosed clamping apparatus of the utility model embodiment.
The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of injection machine, comprises template and clamping apparatus.With reference to figure 1, template comprises patrix 11, middle mould 21, counterdie 31; Clamping apparatus comprises the piece 12 of unblanking, latch segment 23, matrix holder 22, and is inserted in the U type pull bar 32 in the middle of the matrix holder 22.The side of mould 21 during two arms of matrix holder 22 vertically are installed in, the part end face of its two arm all contacts with latch segment 23; The closing end level of U type pull bar 32 is installed in the side of counterdie 31, and the termination of its two arm is provided with projection 321 in the face of the face of counterdie 31; Width between 32 liang of arms of U type pull bar is greater than the width of piece 12 of unblanking, so the piece 12 of unblanking can not have moving around of interfering between two arms of U type pull bar 32.A unblank end of piece 12 is installed in the side of patrix 11, and its other end is provided with locked mode button one, and is suspended on outside the patrix 11.Latch segment 23 bottoms are provided with two springs 231, and its top is provided with locked mode button two; Latch segment 23 is during the locating slot through middle mould 21 sides is fixed on the mould 21.
During injection moulding machine mould open, patrix 11, middle mould 21, and counterdie 31 moves under cylinder or oil cylinder effect; Because the 321 pairs of latch segments 23 of projection on the U type pull bar 32 are exerted pressure; Spring 231 is pressed short, and latch segment 23 is descended rapidly, thereby locked mode button two breaks away from locked mode button one; That is, lost cooperation between them.At this moment unblank piece 12 rises, and has realized die sinking.Rise or descend owing to control latch segment 23, thereby locked mode button two is cooperated with locked mode button two or separate, can effectively reduce the frictional force of unblanking between piece 12 and the latch segment 23, so the life-span of this injection machine is long through spring 231.
During the injection machine matched moulds; Patrix 11, middle mould 21, and counterdie 31 moves under cylinder or oil cylinder effect, when locked mode button one moves to locked mode button two tops; Because the projection 321 on the U type pull bar 32 is not being exerted pressure to latch segment 23; Latch segment 23 moves upward under the elastic force effect of spring 231, locked mode button two is matched with locked mode button one, thereby realized locked mode.In addition, the contact-making surface group of locked mode button one and locked mode button two includes horizontal plane 121 and vertical plane 122, because horizontal plane 121 is orthogonal with vertical plane 122, makes clamp force bigger, so the machining accuracy of this injection machine is than higher.
In addition, four sides of template are equipped with a clamping apparatus, and clamping apparatus is located at the centre of side, have reached dynamic balance with regard to the clamp force that makes template receive like this.Thereby avoided template to deform because of unbalance stress, so the machining accuracy of this injection machine is than higher.
It should be noted that present embodiment do not do qualification to the number of clamping apparatus, its number also can be eight except being four, 12 etc.; Present embodiment is not done qualification to the number of spring 231 yet, and its number also can be three except being two, four etc.
Can find out that through technique scheme injection machine disclosed in the utility model has been installed the clamping apparatus of position symmetry on template, make the stressed balance that reaches of template, has avoided template to be out of shape because of unbalance stress, thereby has improved machining accuracy; And on the piece 12 of unblanking, locked mode button two is set, locked mode button one is set, through mould button two and the locked mode button one incompatible increase clamp force that matches, to improve machining accuracy on latch segment 23; Also be provided with groups of springs in the bottom of latch segment 23; When matched moulds and die sinking, control latch segment 23 with groups of springs and rise or descend, can effectively reduce the frictional force that locked mode button two and locked mode button one receive; Therefore this injection machine has the machining accuracy height, and long advantage of life-span.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
