Abstract
The invention discloses a material closing device for an injection molding machine, aiming at providing the material closing device for the injection molding machine which is simple in structure, not easy to block and convenient to maintain. In order to solve the problem, the technical scheme adopted by the invention comprises a material injection cylinder, a material storage barrel and an injection head, wherein a piston of an injection oil cylinder of the material injection cylinder is connected with the material storage barrel; the bottom of the material storage barrel is connected with the injection head; and a material duct is formed in the injection head. The material closing device for the injection molding machine is characterized in that a material closing groove is formed in the injection head; the material closing groove is connected with a material closing plate in a sliding way; an open/close duct which is matched with the open/close state of the material duct is formed in the material closing plate; an oil cylinder is arranged on one side of the material closing plate; and the piston of the oil cylinder drives the material closing plate to slide backward and forward in the material closing groove. Compared with the conventional material closing device of the injection molding machine, the invention has the characteristics that the material closing device for the injection molding machine is simple and reliable in structure, convenient to maintain, not easy to block and the like.
Description
Technical field
The present invention relates to the pass materials device of a kind of injection machine, particularly a kind of injection machine.
Background technology
Injection machine has another name called injection (mo(u)lding) machine or injector.It is to utilize mould for plastics to process the main former of the plastic products of different shape thermoplastic or thermosetting material.Mainly be divided into vertical, horizontal injection press, injection machine passes on moving system, electric control system, lubricating system, heating and cooling system, safety monitoring system etc. to form by injecting systems, matched moulds system, hydraulic pressure usually.Wherein the injection head in the injecting systems is provided with the material duct that is communicated with the material stock tube, is the generation of anti-leak-stopping material situation, at the material opening of the channel pass materials device is set.The shortcoming that tradition is closed materials device is a complex structure, is prone to block up, and safeguards problems such as inconvenience, as after being blocked, the expense material that closes materials device is difficult to be cleared.
Summary of the invention
