Abstract
The invention discloses a novel mould opening sequence controller which is mainly composed of a draw bar, a draw bar fixed block, a draw bar stop block, a dial pin, an oscillating bar, an oscillating bar permanent seat, a pin roll and a spring. The invention is characterized in that the round dial pin passing through the upper end of the oscillating bar is mutually abutted with a boss with an inclined plane on the lower part of the draw bar so as to separate the projecting edge of the upper end of the oscillating bar from the draw bar fixed block. Because the dial pin is a cylinder and the boss of the lower part of the draw bar is provided with a slope, the dial pin and the boss have smooth contact and reliable and stable action after being abutted and do not have action dead point. In addition, because the lower part of the oscillating bar is sheathed in the U-shaped groove of the oscillating bar permanent seat, the controller does not horizontally swing, so that action precision and reliability are higher.
Description
Technical field
The present invention relates to a kind of mould accessory, particularly relate to a kind of novel mould opening sequence controller.
Background technology
Plastic injection mould is an instrument of producing plastic products, uses very extensive.In plastic products injection moulding, should control the opening sequence of mould die joint for the needs that satisfy moulding process.When mould has two die joints; When it is opened by the requirement of moulding technology certain sequence to be arranged; To control the mould opening force on the different die joints for this reason; Open from the less die joint of mould opening force earlier when making moulds open, and then open the bigger die joint of mould opening force, coagulate material and plastic products with the convenient running gate system of from mould, taking out.What often adopt at present is the swinging hook type mould opening sequence controller, and this swinging hook type mould opening sequence controller reliable in action property of commonly using is relatively poor, and its appearance and size is different with the difference of mould, and the adjustment difficulty is installed, and is difficult to realize standardization.
Summary of the invention
The object of the present invention is to provide a kind of reliable in action and level and smooth, easy-to-install novel mould opening sequence controller.
For realizing above-mentioned purpose, technical solution of the present invention is:
The present invention is a kind of novel mould opening sequence controller, and it mainly is made up of pull bar, pull bar fixed block, pull bar limited block, finger, fork, fork holder, bearing pin and spring; The top of described pull bar is fixed on top first template of mould, and its underpart has a boss, and this boss dual-side longitudinally is the inclined-plane; Described pull bar fixed block is fixed on top second template of mould, between first template and second template, has die joint; Described fork upper end has a horizontal convex edge, but this horizontal convex edge holding is on the pull bar fixed block; Described finger crosswise fixed is set in fork upper end and two ends pass, and the boss of itself and pull bar bottom is relative, in the process of moving up and down, can lean with the boss of pull bar bottom; The fork bottom is hinged on the fork holder through bearing pin, and the fork holder is fixed on the lower bolster; Described spring is nested with in the spring eye of fork holder, and the two ends of spring lean respectively on fork tail end and lower bolster.
The present invention also comprises a pull bar limited block, and this pull bar limited block is fixed on the upper end of fork, and its width forms cascaded surface greater than fork upper end width with the fork upper end, and this cascaded surface constitutes the horizontal convex edge of above-mentioned fork upper end.
Described fork holder is the grooved member with U-lag, and the bottom of fork is movable to be nested with in this U-lag, and can teeter.
Described finger is a cylinder.
After adopting such scheme, the present invention leans through circular finger that passes the fork upper end and the boss that the pull bar bottom has the inclined-plane each other, and the convex edge on the fork is separated with the pull bar fixed block.Because finger is cylinder, the boss of pull bar bottom has the inclined-plane, and both lean very level and smooth, smooth and easy of back contact, moves reliable and stablely, the dead point can not occur moving.In addition, because the bottom of fork is nested with in the U-lag of fork holder, and can teeter, operation precision and reliability are higher.
Below in conjunction with accompanying drawing and specific embodiment the present invention is further described.
Description of drawings
Fig. 1 is an axonometric drawing of the present invention;
Fig. 2 is a front view of the present invention;
Fig. 3 is that top of the present invention first template and second template begin the state diagram of branch mould;
Fig. 4 is that finger of the present invention and pull bar lower boss lean state diagram;
Fig. 5 is pull bar of the present invention and the complete released state figure of fork.
The specific embodiment
With reference to shown in Figure 2, the present invention is a kind of novel mould opening sequence controller like Fig. 1, and it mainly is made up of pull bar 1, pull bar fixed block 2, pull bar limited block 3, finger 4, fork 5, fork holder 6, bearing pin 7 and spring 8.
The top of described pull bar 1 is fixed on top first template (panel) 10 of mould, and its underpart has a boss 11, and this boss 11 dual-side longitudinally is inclined-plane 12; Described pull bar fixed block 2 is fixed on top second template 20 of mould, between first template 10 and second template 20, has die joint.
For upper end and pull bar fixed block 2 upper surfaces that make fork 5 form clamping, need have a convex edge on fork 5 tops, this convex edge can directly be processed to form on fork 5 tops, also can use the mode that adds pull bar limited block 3 always and form.In the present embodiment, commonly used is the mode that adds pull bar limited block 3.Described pull bar limited block 3 is fixed on the upper end of fork 5, and its width forms cascaded surface 31 greater than fork 5 upper end width with fork 5 upper ends, and this cascaded surface 31 constitutes the convex edge on fork 5 tops, but cascaded surface 31 holdings are in pull bar fixed block 2 upper surfaces.
Described finger 4 is a cylinder, and crosswise fixed is set on the pull bar limited block 3 and two ends pass, and the boss 11 of itself and pull bar 1 bottom is relative, in upper and lower moving process, can lean with the boss 11 of pull bar 1 bottom.
Described fork holder 6 is fixed on the lower bolster 30; Fork holder 6 is for having the grooved member of U-lag 61; Movable being nested with in this U-lag 61 and through bearing pin 7 in the bottom of fork 5 is hinged on the fork holder 6, because the restriction fork 5 of U-lag 61 can teeter.Described spring 8 is nested with in the spring eye 62 of fork holder 6, and the two ends of spring 8 lean respectively on the sidewall of fork 5 tail ends and lower bolster 30, makes fork 5 to swing for fulcrum by bearing pin 7.
Operation principle of the present invention:
1, as shown in Figure 3, step surface 31 holdings of pull bar limited block 3 of upper end that are fixed on fork 5 are in pull bar fixed block 2 upper surfaces;
2, as shown in Figure 4, finger 4 leans with pull bar 1 lower boss 11, and fork 5 is outwards swung around bearing pin 7, and the step surface 31 of pull bar limited block 3 separates with pull bar fixed block 2 upper surfaces;
3, as shown in Figure 5, pull bar 1 separates with fork 5 fully, and fork 5 is inwardly swung around bearing pin 7 under the effect of the spring force of spring 8.
