The hot flow path heater embeds assembly tooling
Technical field
The present invention relates to a kind of processing tool of hot runner mould, relate to the embedded heater assembly tooling that a kind of hot runner mould is used specifically.
Background technology
Compare with traditional cold runner mould; Hot runner mould has advantages such as economizing in raw materials, enhances productivity and is extensively adopted; Nozzle is as the critical piece in the hot runner mould; Usually in the groove of its nozzle body outer surface, be embedded with winding heater, heater coil has three faces to paste mutually with nozzle body, and heating properties improves greatly.The existing interior manual mode that adopts usually of groove that is embedded into embedded heater the nozzle body outer surface: embed the heater of vertical bar and be wrapped in the groove of nozzle body outer surface earlier through manual; Because the material stiffness of heater is bigger; Whole assembling process not only efficient is lower, and assembly quality is also bad, and the applying degree that is embodied in heater and groove is relatively poor; Have the part heater can be above the nozzle body outer surface, also need through strike, means such as pressure repair.
Summary of the invention
For overcoming above-mentioned defective, the present invention aims to provide and a kind ofly can improve efficiency of assembling greatly, also can guarantee that the hot flow path heater of assembly quality embeds assembly tooling simultaneously.
For achieving the above object; The technical scheme that the present invention adopts is: a kind of hot flow path heater embeds assembly tooling; Comprise a pedestal be fixed on the pedestal and with parallel plane two guide rails of pedestal; An end that it is characterized in that said pedestal is fixed with an adjustable hold down gag, and said adjustable hold down gag comprises a scroll chuck that compresses that is fixed on the pedestal, is fixed with a pressure roller free to rotate respectively on said three movable claws that compress scroll chuck; The axis of said pressure roller is with to compress scroll chuck axle centre distance identical, and the axis of said pressure roller is parallel to each other; Can move along guide rail on the said guide rail and be connected with a reducing motor; Said reducing motor and a floor push control connection; The output shaft of said reducing motor is connected with a fixedly scroll chuck with one heart towards adjustable hold down gag on the output shaft of said reducing motor; Saidly compress scroll chuck and fixedly the center of scroll chuck is on same axis, said to compress scroll chuck parallel with guide rail respectively with the central axis of fixing scroll chuck.
Be connected with a cylinder on the end of said reducing motor away from output shaft, said cylinder and a gauge tap control connection, the cylinder body of said cylinder is fixed on the pedestal.
The base of said reducing motor is provided with a linear bearing, and said linear bearing and guide rail are slidingly connected.
Adopted hot flow path heater of the present invention to embed assembly tooling; Fix nozzle to be assembled or sleeve through fixing scroll chuck; Be pressed into heater wire in the groove of nozzle or sleeve body outer surface through three pressure rollers that compress on the scroll chuck again; Because fixedly scroll chuck slowly rotation under the driving of reducing motor when being pressed into heater wire; Thereby make heater wire all embed in the groove of nozzle or sleeve body outer surface, the whole operation process was both convenient, and assembly quality also is guaranteed.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: the 1-pedestal, the 2-guide rail, the adjustable hold down gag of 3-, the 4-reducing motor, the 5-cylinder, the 6-floor push, the 7-gauge tap, the 8-linear bearing, the 9-nozzle, 11-compresses scroll chuck, the 12-pressure roller, 21-is scroll chuck fixedly.
The specific embodiment
As shown in Figure 1; The invention discloses a kind of hot flow path heater and embed assembly tooling, comprise a pedestal 1 be fixed on the pedestal 1 and with pedestal 1 parallel plane two guide rails 2, its innovative point is that mainly an end of said pedestal 1 is fixed with an adjustable hold down gag 3; Said adjustable hold down gag 3 comprises that one is fixed on and compresses scroll chuck 11 on the pedestal 1; Be fixed with a pressure roller free to rotate 12 respectively on said three movable claws that compress scroll chuck 11, the axis of said pressure roller 12 is with to compress 11 centre distances of scroll chuck identical, and the axis of said pressure roller 12 is parallel to each other; Like this; Compress scroll chuck 11 through adjusting, make three pressure rollers 12 do simultaneously to move leaving in opposite directions or mutually of scroll chuck 11 centers, so that regulate the distance between three pressure rollers 12 and the nozzle to be assembled 9 to compressing with movable claw;
Can move along guide rail 2 on the said guide rail 2 and be connected with a reducing motor 4; Said reducing motor 4 and floor push 6 control connections; The output shaft of said reducing motor 4 is connected with a fixedly scroll chuck 21 with one heart towards adjustable hold down gag 3 on the output shaft of said reducing motor 4; The said center that compresses scroll chuck 11 and fixing scroll chuck 21 is on same axis, and said to compress scroll chuck 11 parallel with guide rail 2 respectively with the central axis of fixing scroll chuck 21.
During concrete operations; Earlier reducing motor 4 and connection fixedly scroll chuck 21 above that to moving away from adjustable hold down gag 3 directions; And there is not nozzle 9 to be assembled an end of groove to be clamped in fixedly on the scroll chuck 21; Make the axis of nozzle 9 and fixedly after the dead in line of scroll chuck 21, the scroll chuck 21 that is fixedly clamped is fixed on fixedly on the scroll chuck 21 nozzle 9;
Move reducing motor 4 and connection fixedly scroll chuck 21 above that to adjustable hold down gag 3 directions then; One section that on nozzle 9, has groove gets in three pressure rollers 12 fully; And adjusting compresses scroll chuck 11; Make the tangent applying of periphery of the periphery and the nozzle 9 of three pressure rollers 12, and put into the head of nozzle 9 outer surface grooves to a stature of heater wire;
At last, press the direction of rotation of nozzle 9 outer surface grooves, through floor push 6 operation reducing motors 4 forward or reverse; Drive is fixed on nozzle 9 forward or reverse on the fixing scroll chuck 21; In nozzle 9 rotating process, three pressure rollers 12 are done reverse rotation simultaneously under the drive of nozzle 9, and heater wire twines and embed in nozzle 9 outer surface grooves with the rotation of nozzle 9; And under the compressing of three pressure rollers 12, embed fully in nozzle 9 outer surface grooves, promptly accomplished embedded heater assembling.
In order to make the mobile convenient of reducing motor 4 and connection fixedly scroll chuck 21 above that; Also be in order to prevent that nozzle 9 damages because of collision in moving process simultaneously; Another innovative point that hot flow path heater of the present invention embeds assembly tooling is to be connected with a cylinder 5 on the end of said reducing motor 4 away from output shaft; Said cylinder 5 and gauge tap 7 control connections, the cylinder body of said cylinder 5 is fixed on the pedestal 1.Like this, operating personnel only need pass through the flexible of gauge tap 7 control cylinders 5, just can realize reducing motor 4 moving along guide rail 2 easily.
In order to make the resistance of reducing motor 4 when guide rail 2 moves littler; Simultaneously also assurance reducing motor 4 along in guide rail 2 moving process; Fixedly the center of scroll chuck 21 and the center that compresses scroll chuck 11 are all the time on same axis; The base of said reducing motor 4 is provided with a linear bearing 8, and said linear bearing 8 is slidingly connected with guide rail 2.
