Abstract
The invention discloses a three-way hot runner direction-changing device controlled by a rocker arm type heat insulated oil cylinder. The device is characterized by comprising a changing basal body, a heat insulated changing oil cylinder and a rocker arm, wherein the changing basal body is provided with a T-shaped three-way changing valve core connected with the heat insulated changing oil cylinder by the rocker arm. By swinging of the rocker arm, each two runners of the T-shaped three-way changing valve core are communicated, material permeation is avoided, the changing valve core is provided with a metallic sealing member, and the changing of the runner of the valve core is realized by rotation, so that the material permeation phenomenon caused by possible material carrying existing in the common drawing-inserting type valve core is eliminated; in addition, an interlayer is arranged in the heat insulated cylinder body and cooling water flows by the interlayer, so the heat insulated oil cylinder has the cooling effect, the temperature of an oil seal in the oil cylinder does not rise along with the rise of the outside temperature, and the problem that the oil seal is aged caused by heating is solved.
Description
Technical field
The present invention relates to a kind of three-way hot runner direction-changing device of rocker arm type heat insulated oil cylinder control, this device is mainly used in conversion or the sealing of heating liquid runner, and this device is applicable to plastics machine that plastics machine, injection and preformed that extrusion injection molding machine, injection and pressurize separate separate and other need the occasion of three-way hot runner direction conversion.
Background technique
Generally, just change the position of runner by the way of spool axial displacement in the conversion of injection machine industry runner, in order to make liquid change flow direction, but when liquid is the liquid of the higher liquid of temperature or melting, the defectives such as this kind changing valve exists that the conversion body volume is large, three-way valve can produce the bleed phenomenon and owing to being subjected to the impact of high temperature, and the oil sealing of power source (such as oil cylinder) is aging fast.
Summary of the invention
Technical problem to be solved by this invention is bleed and the oil sealing problem of aging that overcomes three-way valve in the prior art, and a kind of heat insulated oil cylinder control three-way hot runner direction-changing device that uses rocker structure is provided.When this covering device satisfies the runner conversion, solve bleed problem and oil sealing aging, and compact structure.
The technological scheme that the present invention solves the problems of the technologies described above employing is: the three-way hot runner direction-changing device of this rocker arm type heat insulated oil cylinder control, be characterized in: comprise conversion matrix, heat insulation conversion oil cylinder and rocking arm, be provided with T-shaped three-way change-over valve core on the conversion matrix, the conversion spool is connected with heat insulation conversion oil cylinder by rocking arm.Thereby realize the in twos connection of T-shaped three-way change-over valve core by the swing of rocking arm, for guaranteeing not bleed, be provided with metal seal at the conversion spool, and spool is the conversion that reaches runner through rotation, eliminated the bleed phenomenon that conventional draw and insert-type spool conversion may cause with material.In addition owing in the middle of the heat insulation cylinder body interlayer being arranged, and can lead to cooling water, therefore heat insulated oil cylinder has cooling effect, so the oil sealing of oil cylinder inside can not raise because of the temperature of outside and raise, and is heated and aging problem therefore solved oil sealing.
On the conversion spool of the present invention metal seal is housed, this metal seal is arranged on the right and left of conversion spool, conversion spool two ends are arranged on the conversion matrix by screw by end cap and connecting plate respectively, and the changing valve mandrel radially freely rotates to fixing.The effect of metal seal is to guarantee that spool plastics of its inner molten state in course of action are non-leakage.
Heat insulation conversion oil cylinder of the present invention comprises cylinder cover, oil cylinder protecgulum, piston rod, heat insulation cylinder body, piston, oil cylinder bonnet, is provided with thermal-protective coating in the middle of the heat insulation cylinder body, and is provided with intake-outlet at heat insulation cylinder body upper and lower end.Heat insulation cylinder body two ends are provided with oil cylinder protecgulum and oil cylinder bonnet, be connected by connecting bolt between oil cylinder protecgulum, oil cylinder bonnet and the heat insulation cylinder body, make heat insulation cylinder body, oil cylinder protecgulum, oil cylinder bonnet form one, be provided with cylinder cover on the oil cylinder protecgulum, be used for fixing seals.Piston rod passes the oil cylinder protecgulum, cylinder cover is arranged on heat insulation cylinder interior, and piston rod one end connects piston, and the other end is provided with connecting sleeve.Be respectively arranged with oil inlet and outlet on oil cylinder protecgulum and the oil cylinder bonnet, when the oil inlet and outlet of pressure oil from the oil cylinder bonnet enters, and when fuel-displaced from the oil inlet and outlet of oil cylinder protecgulum, can drive piston to move, by piston rod, connecting sleeve transferring power, the final conversion valve core rotation that drives.When the oil inlet and outlet of pressure oil from the oil cylinder protecgulum enters, and when fuel-displaced from the oil inlet and outlet of oil cylinder bonnet, drive piston to move, by piston rod, connecting sleeve transferring power, band movable valve plug counter-rotation namely resets.
For reaching effect of heat insulation, be provided with thermal-protective coating in the middle of the heat insulation cylinder body, and at the upper and lower intake-outlet that is provided with of cylinder body, can when temperature is high, use the water quench oil cylinder, thereby reach better effect of heat insulation, can be good at playing the effect of protection oil cylinder oil seal.
Oil cylinder bonnet of the present invention is arranged on the connecting plate by rotating shaft and set screw nut, connecting plate is connected with the conversion matrix, piston rod and connecting sleeve one end are with being threaded, setscrew nut is arranged on the piston rod, the connecting sleeve the other end is connected by link pin with rocking arm; be in transmission connection by key between rocking arm and the conversion spool, also be provided with baffle plate on the conversion spool.The effect of baffle plate is to guarantee in course of action, and rocking arm can not thrown off with the conversion spool.
Be provided with oilless bearing between rotating shaft of the present invention and the oil cylinder bonnet, its effect is that heat insulation conversion oil cylinder can freely be rotated around rotating shaft.
Being equipped with between connecting sleeve of the present invention and the link pin, between rocking arm and the link pin is Spielpassung, its objective is to make between connecting sleeve, the rocking arm and can freely relatively rotate.
The present invention compared with prior art has the following advantages: three-way hot runner spool switch technology is that the draw and insert-type spool is main at present, compared to existing technology, changing valve is by changing spool, eliminated the possibility of the bleed that pulls and pushes spool and cause, and be provided with metal seal on the spool, guaranteed the bleed phenomenon that rotation produces.And the action that rocking arm type makes oil cylinder drive Spool rotating more easily realizes.Owing to changing by three-way hot runner direction, therefore oil cylinder has the danger of being heated, the oil cylinder inner oil seal is heated and accelerated ageing, and heat insulation cylinder body of the present invention is to lead to cooling water by interlayer or in necessity, therefore outside heat can't import in the oil cylinder substantially, is heated and the hidden danger of accelerated ageing thereby eliminated oil sealing.
