Abstract

The utility model relates to a two-plate type injection molding machine, in particular to an adjustment device for a movable template of an injection molding machine. The adjustment device comprises a movable template, a braking nut, a pull rod, a positioning frame, a transmission gear group and a wedge block, wherein the positioning frame is arranged on the movable template on the braking nut side; transmission gears are arranged on the positioning frame and the transmission gear group comprises a driving gear and a tail end output gear; the driving gear is connected with the movable template; a cam is coaxially arranged on the tail end output gear; the wedge block is arranged on the positioning frame through a spring; and the spring enables the wedge block to intend to move toward the positioning frame. The adjustment device is rational in structural design; an automatic pitch adjustment mechanism linked with the pull rod can automatically adjust the distance between the braking nut and the pull rod, so that a requirement on the braking precision of the two-plate type injection molding machine is met; furthermore, an extra power device is not required, so that a large sum of cost is reduced; and the adjustment device has obvious economic benefit.

Description

The adjusting device of Injection Motor Template

Technical field

The utility model relates to a kind of double-plate injection molding material machine, and the precision that specifically relates to moving platen is regulated.

Background technology

The clamping of existing double-plate is mainly by two kinds of the straight locking-type of hydraulic pressure and combined types.The straight locking-type two plate machine matched moulds structures of hydraulic pressure mainly are to promote moving platen through the rapid mould-moving structure to move, and pass through Mode-locking oil cylinder then with mold-locked.Exemplary complex formula two plate matched moulds structure course of action are following: be fixed on quick hydraulic oil cylinder driving moving platen fast moving on the quiet template, with mould closes; Pass through positioning and locking device relative fixed between moving platen and the pull bar this moment, spurs pull bar with mold-locked through Mode-locking oil cylinder then.

The straight locking-type two plate facility of hydraulic pressure have the automatic mold-adjustment function, but the hydraulic system relative complex of the straight locking-type two plate machines of hydraulic pressure, reliability is relatively poor, and the size that takes up room is compared three plate machines does not have obvious advantages.In combined type two plate machine structures, the mode transfer structure generally is divided into following several kinds: 1. in Mode-locking oil cylinder, pass through the fine adjustment draw rod positions, pull bar tooth top and the tooth root position of going into the lock nut are agreed with, location and then locking pull bar; 2. regulate into the lock nut location through actuating units such as motors, pull bar and the position of going into the lock nut are agreed with, location and then locking pull bar.Four pull bars or nut all need increase independent power set in these two kinds of structures, and oil piping system complicates simultaneously, has increased sizable cost.If be used for middle-size and small-size two-plate injection machine, there is not tangible benefit on the integrated cost.

Summary of the invention

Therefore, the purpose of the utility model is to provide a kind of moving platen of realizing in making process, to carry out the adjusting device that the Injection Motor Template of actuating unit was regulated and do not needed to increase separately to precision automatically.

The purpose of the utility model realizes through following technical scheme.

A kind of adjusting device of Injection Motor Template comprises moving platen, goes into lock nut and pull bar.

Also comprise locating rack, locating rack is installed on the moving platen of lock nut side.

Also comprise driving gear set, travelling gear is installed on the locating rack, and driving gear set comprises driving wheel and terminal output wheel again, driving wheel and moving platen interlock, and terminal output wheel is provided with cam coaxially.

Also comprise voussoir, voussoir is installed on the locating rack through spring, and spring makes voussoir have the trend to the locating rack motion.Be provided with drive link between said cam and the voussoir, drive link one end cooperates with cam, and the drive link other end is connected with voussoir.Said voussoir moves with drive link under the acting in conjunction power of drive link and spring and moves, voussoir overcomes spring tension pushed to the lock nut by drive link after, voussoir with go into the lock nut each other against.

Technique scheme also can be done further perfect as follows.

The teeth of said driving wheel and pull rod screw engagement.

Or be installed on the pull bar driving wheel and band teeth engagement synchronously through being with synchronously.

Said driving gear set is a train of reduction gears.

The utility model reasonable in design with the automatic regulating tooth spacing mechanism that pull bar has the interlock function, can be regulated the position between lock nut and the pull bar automatically, and realization two-plate injection machine band-type brake precision is sent out requirement.Need not increase extra power set, practice thrift sizable cost, have tangible economic benefit.

The specific embodiment mode.

Below in conjunction with accompanying drawing and embodiment the utility model is done further to detail.

Embodiment 1, and in conjunction with Fig. 1 to Fig. 3, a kind of adjusting device of Injection Motor Template comprises moving platen 1, goes into lock nut 2, pull bar 3, locating rack 4, driving gear set, voussoir 5, drive link 6.

Said locating rack 4 is installed on the moving platen 1 of lock nut 2 sides.

Said driving gear set is installed on the locating rack 4; Driving gear set is a train of reduction gears, and it comprises driving wheel 7 and terminal output wheel 8 again, and the teeth of driving wheel 7 are connected with the screw-threaded engagement of pull bar 3; So that driving wheel 7 and moving platen 1 interlock, terminal output wheel 8 is provided with cam 9 coaxially.

Said voussoir 5 is installed on the locating rack 4 through spring 10.

Said drive link 6 is located between cam 9 and the voussoir 5, and drive link 6 one ends cooperate with cam 9, and drive link 6 other ends are connected with voussoir 5.Said terminal output wheel rotates with driving cam 9 in driving wheel 7 rotation processes, under acting force of the spring, makes drive link 6 on 0 position to maximum position, do reciprocal variation simultaneously.When go into lock nut 2 with pull rod shaft on vertical direction in the motion process; Voussoir makes the axial location into the lock nut change; Make tooth top and tooth root aligned in position into lock nut and pull bar; Go into lock nut upper sensor and send signal and go into that lock nut and pull bar are last accomplishes lock locking, carry out the locked mode action, moving platen of the present invention is only transferred moving platen in a pitch scope.During the demoulding, go into lock nut 2 and outwards move, get back to initial position.

Embodiment 2, and in conjunction with Fig. 4 and Fig. 5, embodiment 2 is that with the difference of embodiment 1 driving wheel is not to mesh with pull bar; Be with 12 synchronously but on pull bar 3, install one; Be with synchronously 12 with driving wheel 7 teeth engagements, when moving platen move, band and driving wheel relative position changed synchronously; Driving wheel 7 is rotated, and other structure is then consistent with embodiment 1.
