Due to the nozzle touch device with detected injection molding machine contact force, the condition that the touch force cannot be precisely detected because the compression amount of the spring is not accurate can be avoided, and meanwhile, the phenomenon of inaccurate nozzle touch force caused by the change of a spring coefficient due to long-time working can also be avoided.
Description
Technical field
The utility model relates to a kind of nozzle contact device of injection machine.
Background technology
Chinese patent document CN 2717659Y discloses the detectable nozzle contact device of a kind of injection machine contact force, and injecting assembly is installed on the guiding slide, slide through one be installed on the linear drive apparatus below it lead screw gear drive.So injecting assembly can be realized advancing on the linear drive apparatus that the leading screw tumbler is formed, backward movement.When injecting assembly advanced and contacts with mould, motor continues to drive the leading screw rotation made screw realize seesawing, and makes the advance and retreat camber of spring produce spring force.This spring force is passed to injecting assembly through connector, leading screw, and the nozzle and the mould that make the barrel front end of injecting assembly install produce a contact force, to avoid producing leakage between nozzle and the mould gate.Nozzle touch force can be adjusted through elastic constant and camber of spring stroke.The shortcoming of the detectable nozzle contact device of this injection machine contact force is, the deformation stroke of spring generally is to set through electric eye, and the desired location of electric eye is to regulate definitely through manual, so actual nozzle contact force and setting value are devious.If actual value is bigger than normal, the major accident that can cause mould to damage; If actual value is less than normal, can cause raw material to be revealed.Another shortcoming; The elastic constant of spring is not changeless; Along with the spring increase of service time, its intrinsic elastic constant can diminish, therefore under same deflection situation; The nozzle touch force of generation just is difficult for calculating than original little and this power, therefore can cause the generation of raw material leakage along with the increase of service time.
Summary of the invention
The utility model provides a kind of injection machine contact force detectable nozzle contact device for solving the problems of the technologies described above; It can accurately detect the nozzle touch force of actual generation through pressure sensor, has avoided simultaneously owing to the elastic coefficient changes the generation that produces the inaccurate phenomenon of nozzle touch force.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
The detectable nozzle contact device of injection machine contact force; It is characterized in that: parallelly on fuselage be fixed with a pair of line slideway; On the slide block of line slideway, be separately installed with penetrate the platform rear support and penetrate platform before bearing, the front and back bearing connects through guide post, and guide plate is installed on guide post; Can horizontally slip in that guide post is cofree; Ball-screw is fixed on to be penetrated on the platform rear support, and motor is installed on the bearing block and is connected with ball-screw through shaft coupling, and the nut of ball-screw is connected with guide plate; Position, the left and right sides at guide plate is equipped with connecting rod, and at the fixing a plate of the other end of two connecting rods, the center fixed of this connecting plate has another connecting rod; Another connecting rod is with a sliding panel, and another connecting rod front end is fixed a fixed head, mounting spring between fixed head and sliding panel.
Above-mentioned ball-screw is fixed on through bearing block and penetrates on the platform rear support.
Above-mentioned ball-screw nut is connected with pressure sensor through connecting ring, and pressure sensor is connected with guide plate.
Said structure drives leading screw through the motor rotation and realizes seesawing of feed screw nut, and feed screw nut is realized seesawing through the feasible platform moving-member of penetrating such as guide plate, connecting rod and spring.When nozzle touches mould,, motor produces a nozzle touch force thereby continuing to drive feasible compression spring.
The utility model is owing to installed pressure sensor; Therefore nozzle touch force can accurately be detected through the pressure sensor that is installed on the feed screw nut, thereby can avoid taking place can't accurately detecting because of amount of spring compression is inaccurate contact force, also can avoid causing the generation of the inaccurate phenomenon of nozzle touch force because of the variation of the elastic coefficient owing to work long hours simultaneously.
Description of drawings
Fig. 1 penetrates the stereogram of platform moving-member for the utility model.
Fig. 2 penetrates the vertical view of platform moving-member for the utility model.
Fig. 3 penetrates platform moving-member cutaway view for the utility model.
Mark is following among the figure: 1 whole moves motor, 2 motor shaft bearings, and 3 penetrate the platform rear support, 4 line slideways, 5 guide posts; 6 penetrate the preceding bearing of platform, 7 connecting rods, 8 connecting plates, 9 nuts, 10 connecting rods; 11 fixed heads, 12 springs, 13 sliding panels, 14 nuts, 15 shaft couplings; 16 bearings, 17 feed screw nuts, 18 connecting rings, 19 pressure sensors.
The specific embodiment
Embodiment describes the utility model with reference to the accompanying drawings.
Like Fig. 1, shown in Figure 2, about two parallel linear guides 4 be fixed on the fuselage, bearing 6 is connected on the slide block of line slideway 4 through screw before penetrating platform rear support 3 and penetrating platform, penetrates platform rear support 3 and penetrates the preceding bearing 6 of platform and also be connected through two parallel guide bars 5.
Whole move motor 1 and be fixed on the motor shaft bearing 2, motor shaft bearing 2 then is fixed on penetrates on the platform rear support 3.
Parallel in the position, the left and right sides of guide plate two connecting rods 7 are installed, connecting rod 7 is fixing with connecting plate 8 through nut 9.
In the centre position of connecting plate 8 connecting rod 10 is installed, the other end of this connecting rod is connected with sliding panel 13 through nut 14.There is spring 12 the left-right symmetric position between sliding panel 13 and fixed head 11, and fixed head 11 is fixed on the mould fixed form.
As shown in Figure 3, shaft coupling 15 connects whole motor 1 and the ball-screw bearing 16 of moving, and the leading screw bearing is fixed in the motor shaft bearing 2, and feed screw nut 17 is equipped with pressure sensor 19 through connecting ring 18.
In schematic structure, when motor is delivered to rotation on the screw mandrel, screw mandrel and feed screw nut 17 are because of screw-threaded engagement; So just can make the motion of feed screw nut before and after carrying out, when feed screw nut when moving, through guide plate and connecting rod near motor drive direction; The pulling injecting assembly moves to the mould fixed form; When nozzle contacted with mould, motor continues to export to rotate made feed screw nut continue motion, and then feed screw nut continues promotion and makes sliding panel move and the compression spring; With the locking of motor band-type brake, the compression stress that the spring compression produces detects through pressure sensor after the certain amount of compression spring.So just accurately continue to keep nozzle touch force.When feed screw nut when moving away from motor drive direction, then nozzle is away from the mould direction.
