Abstract
The invention relates to an injection molding device for an injection molding machine, in particular to a single-cylinder and single-action injection molding device. The outside of an injection molding oil cylinder is provided with a plurality of auxiliary oil cylinders additionally, and each auxiliary oil cylinder consists of a spline shaft, an oil cylinder back cover and a plastic injection piston. The injection molding device has the characteristics of reasonable and simple structure, lower production cost, smaller axial length of the injection molding device, lower sealing technology requirement, and the like.
Description
Technical field
The present invention relates to a kind of injection machine injection moulding apparatus, especially relate to a kind of injection moulding apparatus of single-cylinder single-acting.
Background technology
Existing injection machine major part all adopts the single cylinder injection moulding, and injection cylinder need be born two actions, realizes that injection and notes move back two actions.When realize annotating deactuate and do, need be in the rodless cavity oil-feed, so to the length requirement of rodless cavity be sealed and matched and require to have increased the raising of manufacturing cost virtually all than higher, and influence the otherwise technical parameter of injection machine and design.The utility model patent of a single-oil-jar injection device of injection machine by name, the patent No. is: CN200520013429.0, by the oil cylinder bonnet that is fixed with oil motor and the band sealing ring the injection piston cooperate with injection cylinder, power transmission shaft respectively and power transmission shaft and barrel in screw rod connect and compose, injection piston two ends are supported by bearing, bearing is connected on the power transmission shaft, power transmission shaft connects into integral body by power input shaft and oil motor, and an end of power transmission shaft and power input shaft are joined to be incorporated in the injection cylinder and moved.No matter be plasticizing, injecting program, power transmission shaft is left and right in injection cylinder always to be moved, rotation cooperates with splined shaft, be sealed and matched and require the technical need height, notes move back pressure and injection pressure about equally, production cost is higher, and constantly changing of axial length makes it to be not suitable for the injection machine of various models.
Summary of the invention
The present invention mainly is at the existing in prior technology complex structure, production cost is higher, the injection moulding apparatus axial length is bigger, the technical problem that Sealing Technology is had relatively high expectations etc., provide a kind of simple in structure, production cost is lower, and the injection moulding apparatus axial length is less, and Sealing Technology requires lower single-cylinder single-acting injection mould apparatus.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: described injection cylinder is set up some auxiliary cylinders outward, and auxiliary cylinder is made up of splined shaft, oil cylinder bonnet and injection piston.The injection moulding oil cylinder affords action of injection separately, and auxiliary cylinder affords separately annotates the deactuate work, can oversimplify on the structure of injection moulding oil cylinder.
As preferably, the internal diameter of described auxiliary cylinder is less than the internal diameter of injection cylinder.The notes of auxiliary cylinder move back the injection pressure of pressure less than injection cylinder, save many production energy resource consumptions.
As preferably, described injection cylinder is located on the separate different axis with the auxiliary cylinder branch.Can reduce the length of injection moulding apparatus.
As preferably, described injection cylinder one end connects oil motor, and the other end has oil pipe and connects auxiliary cylinder.
Therefore, the present invention has rational in infrastructure simple, and production cost is lower, and the injection moulding apparatus axial length is less, and Sealing Technology requires characteristics such as lower.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present invention;
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, technical scheme of the present invention is described in further detail.
Embodiment 1: set up two auxiliary cylinders 2 outside common injection cylinder 1, injection cylinder 1 was located on the separate different axis with auxiliary cylinder in 2 minutes, can reduce the length of injection moulding apparatus, and auxiliary cylinder 2 is made up of splined shaft, oil cylinder bonnet and injection piston.Injection moulding oil cylinder 1 affords action of injection separately, and auxiliary cylinder 2 affords separately annotates the deactuate work, can oversimplify on the structure of injection moulding oil cylinder 1.The internal diameter of auxiliary cylinder 2 is less than the internal diameter of injection cylinder 1.The notes of auxiliary cylinder 2 move back the injection pressure of pressure less than injection cylinder 1, save many production energy resource consumptions.Injection cylinder 1 one ends connect oil motor 3, and the other end has oil pipe and connects auxiliary cylinder 2 (as shown in Figure 1).
