One end of the collecting cavity is provided with an injection plunger piston connected with an oil cylinder driver and the other end is provided with a nozzle. The outlet of the nozzle is provided in matching with a control valve. With skillful design, simple and reasonable structure, the injection mechanism of the injection molding machine helps to shorten the process flow and obviously reduce the time for injection and keeping pressure, thereby improve the production efficiency and produce production cost.
Description
Technical field
The utility model relates to the injection machine technical field, is specially the injection mechanism of injection machine.
Background technology
Existing injection machine is provided with the feed hopper that is communicated with it on the heating cylinder, be equipped with rotating screw bolt in the heating cylinder, and injection barrel outside is equipped with heating cylinder.Injection process is meant the injection barrel of plastic material being supplied with heating by the feed hopper of injection machine, the screw rod of raw material by continuing to rotate, barrel through external heat produces shear heat again, makes plastic raw materials be fused into flow-like, is pooled in the collection chamber of barrel with the nozzle connection.Because of the lasting rotation of screw rod constantly pools together the plastic raw materials that is flow-like, compiling volume constantly increases, thereby the screw rod that makes rotation moves after oppositely, is similar to when once injecting in the mold cavity when the fluid plastic cement is pooled to some, and then screw rod stops operating.The front end of screw rod is provided with non-return backflow lock, the rear end is provided with the hydraulic jack for the lead-screw reach, the hydraulic cylinder lead-screw of rear end reach like this, and the non-return backflow lock of screw front end cuts out, make screw rod bear injection ram, the propelling fluid raw material enters by nozzle and carries out filling in the shaping mold cavity.Also to continue after the sand off to keep regular hour and pressure, be commonly referred to pressurize.Pressurize also is a crux very, if this procedure time, pressure are improper, goods can occur owing to fill and cause shrink mark so, directly influence Products Quality.Screw rod carried out continuing the second time to rotate to prepare for next technology after injection pressurize program was finished.When fluid material is pooled to when being similar in the injection moulding die cavity once more, machine carries out next driven by program, product cooling in the die cavity, die sinking, holder finished product etc.Therefore, injection is undertaken by the front and back program respectively with two actions that compile of raw material, needs very long process time, and production efficiency is low, and the production cost height directly has influence on economic benefit.
The utility model content
At the above-mentioned problems in the prior art, the technical scheme that the utility model design provides the injection mechanism of injection machine has shortened technological process greatly, has improved production efficiency, has reduced production cost.
The injection mechanism of described injection machine, the feed hopper that is communicated with it is set on heating cylinder, be equipped with rotating screw bolt in the heating cylinder, the outlet that it is characterized in that heating cylinder is communicated with the collection chamber of injection barrel, its exit position is equipped with non-return backflow lock, collection chamber one end is equipped with the injection piston that is connected with hydraulic oil cylinder driving, and the other end is provided with nozzle, and the jet expansion position is equipped with control valve.
The injection mechanism of described injection machine is characterized in that the collection chamber main body is a cylindrical structural, the tapered structure of its right-hand member.
The injection mechanism of described injection machine is characterized in that non-return backflow lock and oil cylinder are connected.
The injection mechanism of described injection machine is characterized in that control valve and oil cylinder are connected.
The injection mechanism of above-mentioned injection machine is skillfully constructed, and is simple and reasonable for structure, shortened technological process, significantly reduced the process time of injection pressurize, improved production efficiency, reduced production cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, the feed hopper 1 that is communicated with it is set on heating cylinder 2, be equipped with rotating screw bolt 3 in the heating cylinder 2, the outlet of heating cylinder 2 is communicated with the collection chamber 9 of injection barrel 11, its exit position is equipped with non-return backflow lock 4, collection chamber 9 one ends are equipped with oil cylinder 12 and drive the injection piston 10 that is connected, and the other end is provided with nozzle 6, and nozzle 6 exit positions are equipped with control valve 7.Non-return backflow lock 4 is connected with cylinder or oil cylinder 5, and control valve 7 is connected with cylinder or oil cylinder 8.Collection chamber 9 main bodys are cylindrical structural, and injection piston 10 is slidingly matched with collection chamber 9 circular cylindrical cavities.The tapered structure of collection chamber 9 right-hand members, narrow gradually to outlet, so that when injection produces faster speed, also be convenient to improve the raising of 7 pairs of nozzles of control valve, 6 outlet envelope material sensitivity.The structure of rotating screw bolt 3 and operation principle thereof do not repeat them here for existing known technology.
During injection pressurize work, non-return backflow lock 4 is sealed heating cylinder 2 and is exported, control valve 7 unlatchings, and oil cylinder 12 drives injection piston 10 work, makes the expulsion pressure of past nozzle 6 directions of fluid material generation in the collection chamber 9.Nozzle 6 connects with the mould charging aperture, raw material is injected typing in the die cavity, raw material in the feed hopper 1 heats through heating cylinder 2 by rotating screw bolt 3 simultaneously, make the raw material fluidify that is heated collect in rotating screw bolt 3 front ends, raw material compiles volume and constantly increases rotating screw bolt 3 is axially dropped back, and reaches that rotating screw bolt 3 stops operating when injecting required fluid material next time.The injection dwell time finishes, and control valve 7 is closed, and the while, non-return backflow lock 4 was opened, and rotating screw bolt 3 promotion front end fluid materials enter in the collection chamber 9 to be prepared for next injection moulding pressurize, so moves in circles.
Adopt above-mentioned injection mechanism, can carry out melten gel in the time of injection, pressurize, plastic material is in heating cylinder 2 heating when being injection, pressurize, raw material is pooled to rotating screw bolt 3 front ends through heating, rotating screw bolt 3 propelling fluid raw materials enter in the collection chamber 9 to injection next time and prepare when carrying out next technology, thereby shortened the technological process cycle greatly, improved production efficiency.
