Abstract
The utility model belongs to the technical field of an injection charge head for an injection moulding machine, and relates to an improvement on the prior art, particularly an injection charge head for a needle valve thermal insulating jacket injected and formed by liquid silica gel. The injection charge head comprises a needle nozzle jacket, a sealing ring, a cold channel water transport jacket, a cold channel jacket, a cylinder attaching jacket, a cylinder bottom cover, a needle valve, a cylinder piston, a cylinder jacket, a screw, a hollow injection charge channel, a water inlet and a water outlet. The injection charge head is characterized in that firstly, the needle valve is arranged and sealed without dripping glue; secondly, the dosage is accurate; thirdly, burrs do not exist; and fourthly, a charge nozzle is directly aligned with a cavity. The utility model saves the raw materials and reduces the labor cost.
Description
Technical field
The utility model belongs to ejection shaping apparatus material injection head technical field, is improvements over the prior art, the needle-valve insulation jacket that the is specifically related to a kind of liquid silica gel ejection formation head that shoots material.
Technical background
Existing liquid silica gel injects to mould, and weak point is that this head that shoots material does not have a needle-valve setting, can not sealing, and tear drop when die sinking makes the product viscose glue bad easily; Dosage is accurate inadequately; Burr are many, waste bigger; Material is chewed and is separated with product etc.
The utility model content
The purpose of this utility model is the head of avoiding above-mentioned weak point of the prior art and the needle-valve insulation jacket of a kind of liquid silica gel ejection formation of providing shoots material, the needle-valve insulation jacket of this liquid silica gel ejection formation head that shoots material has a needle-valve setting, the needle-valve sealing, rubber drop-free; Dosage is accurate; No burr; Expect the outspoken characteristics such as aiming at the product die cavity that connect.
The purpose of this utility model can realize by following measure:
The utility model is chewed overcoat by pin, sealing ring, cold runner fortune water jacket, the cold runner overcoat, cylinder pastes cover, cylinder bottom head, needle-valve, steam-cylinder piston, steam-cylinder lagging, screw, hollow shoots material, water inlet, delivery port is formed, be provided with in the cold runner fortune water jacket that hollow shoots material and needle-valve, outside cold runner, put water inlet and delivery port are set, in cold runner fortune water jacket periphery the cold runner overcoat is set, in the end, lower end that shoots material pin is set and chews overcoat, in the periphery, upper end that shoots material of hollow cylinder is set and pastes cover, paste to put at cylinder cylinder bottom head is set, steam-cylinder piston is set on cylinder bottom head, in the steam-cylinder piston periphery steam-cylinder lagging is set, shoot material and the needle-valve of hollow together is arranged in the cold runner fortune water mantle.
Above-mentioned described needle-valve can be up and down or front and back control stroke shoot material and sealing.
The above-mentioned described material that shoots material head is chewed direct aligning product die cavity.
The utility model has following advantage compared to existing technology:
The one, needle-valve is set, needle-valve sealing, rubber drop-free; The 2nd, dosage is accurate; The 3rd, no burr; The 4th, material is chewed direct aligning product die cavity, the utlity model has conservation and cost of labor.
