Abstract
The present invention discloses a fast precise injection table structure which comprises an injection table head plate component, a glue-injecting tail plate, two glue-injecting oil cylinder components and a glue-melting cylinder component. The glue-injecting oil cylinder components are arranged at two sides of the injection table head component. The glue-injecting tail plate is equipped with an oil motor. The glue-injecting oil cylinder component comprises a cylinder body, the inside of which is provided with a piston cavity which is equipped with a piston rod at the inside, the piston rod is fixedly equipped with a piston, and one end of the piston rod is fixed at the glue-injecting tail plate. The fast precise injection table structure is characterized in that the other side of the piston is equipped with a piston rod without a rod cavity, which extends outside the piston cavity. The additional piston rod of the fast precise injection table structure occupies a certain cubage of the piston cavity and reduces the hydraulic oil quantity of the piston cavity of the part correspondingly, and accordingly, the fast precise injection table structure can reduce the oil return quantity of the piston cavity of the part when glue is injected at a high speed, reduces the oil return speed and further solves the problem of too high noise caused by too high oil return pressure and speed when the original injection table injects the glue at a high speed.
Description
Technical field
The present invention relates to a kind of injection machine and penetrate the platform structure, particularly a kind of twin-tub balance is penetrated the platform structure.
Background technology
The platform mechanism of penetrating of injection machine constitutes by penetrating title board component, injection tailgate, two injection cylinder components and rubber melting cylinder assembly and oil motor, traditional injection cylinder component comprises cylinder body, be provided with plunger shaft in the cylinder body, piston rod is installed in the plunger shaft, be installed with piston on the piston rod, an end of piston rod is fixed on the injection tailgate.The piston-less lumen of injection oil cylinder produced high noisy because return pressure and speed are crossed conference when the high speed injection, thereby operating environment is caused noise pollution.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of quick precise injection platform, this penetrate the platform structure can solve the rodless piston chamber when the high speed injection owing to return pressure and the too high problem of the excessive noise that causes of speed.
The technical solution adopted for the present invention to solve the technical problems is:
Quick precise injection platform, comprise and penetrate title board component, injection tailgate, two injection cylinder components and a rubber melting cylinder assembly, described injection cylinder component is arranged on the both sides of penetrating the title board component, on the described injection tailgate oil motor is installed, described injection cylinder component comprises cylinder body, be provided with plunger shaft in the cylinder body, piston rod is installed in the plunger shaft, be installed with piston on the piston rod, one end of piston rod is fixed on the injection tailgate, the opposite side that it is characterized in that piston is equipped with the rodless cavity piston rod, and the rodless cavity piston rod extends to outside the plunger shaft.
As the preferred embodiment of the present invention, described piston rod interts and is fixed on the piston, and an end of described rodless cavity piston rod is sleeved on the piston rod, and the diameter of rodless cavity piston rod is consistent with the maximum gauge of piston rod.
Above-mentioned rubber melting cylinder assembly comprises a rubber melting cylinder, and screw rod is installed in the rubber melting cylinder, and an end of described screw rod is connected with oil motor.
What the present invention adopted is the cycloid oil motor.
On the described injection cylinder component copper sheathing is installed, described injection tailgate is installed on the injection cylinder component by copper sheathing.
The invention has the beneficial effects as follows: the present invention has additional piston rod in the rodless piston chamber of piston one side, because the piston rod of setting up has occupied a constant volume of plunger shaft, correspondingly reduced the hydraulic pressure oil mass of this part plunger shaft, thereby can reduce the recirculating oil quantity of this part plunger shaft when the high speed injection, reduce oil return speed, and then solve original excessive and too high problem of noise that cause of platform return pressure and speed when the high speed injection of penetrating.
