Abstract
The invention provides a flow regulation mechanism for a runner of an injection mould. The flow regulation mechanism is composed of a fixed template (1), a runner (2), a runner flow regulation bolt (3) and a movable template (4), wherein the runner (2) is arranged between the fixed template (1) and the movable template (4) to form a parting surface. The flow regulation mechanism is characterized in that the movable template (4) is provided with the runner flow regulation bolt (3). According to the flow regulation mechanism for the runner of the injection mould, an internal hexagonal wrench is used for carrying out flow regulation on the runner flow regulation bolt from the parting surface, and the flow regulation mechanism is suitable for the flow regulation when the mould is tested. When the flow regulation mechanism is used in a multi-cavity mould, the runner flow regulation bolt not only can carry out flow control, but also can cut off or reconnect a melt flow flowing to a specific cavity. When the flow regulation mechanism is used in an abnormal-shape multi-cavity mould, the runner flow regulation bolt can realize two functions of a flow regulation bolt and a runner steering pin.
Description
Technical field
The present invention relates to the running gate system of injection mold, especially the Flow-rate adjustment control structure in System of Injection Moulding.
Background technology
System of Injection Moulding is that plastic melt is from the nozzle ejaculation of injection machine, to the general name that enters the stretch journey of flowing through before the die cavity of mould.Running gate system is comprised of sprue, runner, cast gate, cold slug well etc.According to plastic size, the factors such as shape wall thickness, specification requirement, in conjunction with select die joint to consider to arrange form, charging aperture quantity and the position of running gate system simultaneously, guarantee that plastic is normally shaped.
Running gate system is set and also should be taken into account that mould is a cavity per mould or a multi-cavity mold, running gate system need to design according to cavity layout.During cavity structure distribution, should make can fill in each die cavity simultaneously, preferably adopt equalization to be arranged symmetrically with.The position of runner, size, shape, directly affect inherent quality and the presentation quality of plastic.If it is improper to design, easily produce filling badness, weld mark obviously, the injection defect of bubble, buckling deformation, Density inhomogeneity, the excessive even insufficient fill of internal stress.
When the special-shaped multi-cavity mold of design one mould, must consider mobile equilibrium problem, if each plastic part size weight difference is excessive, the injection pressure of each die cavity also has very big difference, and channel size is difficult to regulate, and melt cannot reach flow equilibrium.If imbalance of flow in the special-shaped multi-cavity mold of a mould, the plastic mold filling pressurize that will have is inadequate, and other plastic mold filling is for the special-shaped multi-cavity mold of a mould with multi-cavities and a mould, according to Runner Balance degree, the melt loading time of each die cavity easily produces deviation.When loading time produces deviation, common countermeasure is to adjust the diameter of runner, balanced loading time.In order to adjust flow diameter, need to carry out reaming to runner and append work, or die cavity is divided into some inserting, but so relatively waste time and energy.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of flow channel of injection die flow control device, in System of Injection Moulding, to runner flow, can regulate the bolt of controlling, under mould matched moulds state, by the new type fittings of inner hexagon spanner easy adjustment runner flow, be specially adapted to the mould for types such as cavity and the special-shaped multi-cavities of a mould by this part.
Technical scheme of the present invention is to realize in the following manner: flow channel of injection die flow control device, by solid plate, runner, runner Flow-rate adjustment bolt and moving platen, formed, described runner is located between solid plate and moving platen and forms die joint, it is characterized in that: described moving platen is provided with runner Flow-rate adjustment bolt.
The top of described runner Flow-rate adjustment bolt has two above runners and turns to groove.
Structure of the present invention, carries out flow adjustment from die joint to runner Flow-rate adjustment bolt by inner hexagon spanner, the Flow-rate adjustment when being applicable to mould and carrying out die trial.While using in a mould with multi-cavities, runner Flow-rate adjustment bolt not only can carry out flow-control, can also cut off or reclose the flow of melt that flows to specific die cavity.While using in the special-shaped multi-cavity mold of a mould, runner Flow-rate adjustment bolt can be realized flow adjusting pin and two kinds of functions of runner king pin.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structure distribution figure of runner Flow-rate adjustment bolt in special-shaped two cavity moulds of a mould.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
By Fig. 1, known, flow channel of injection die flow control device, solid plate 1, runner 2, runner Flow-rate adjustment bolt 3 and moving platen 4, consist of, runner 2 is located between solid plate 1 and moving platen 4 and forms die joint, and described moving platen 4 is provided with runner Flow-rate adjustment bolt 3.
By Fig. 2, being known, is the structure distribution figure of runner Flow-rate adjustment bolt in special-shaped two cavity moulds of a mould.The top of runner Flow-rate adjustment bolt 3 has at least two above runners and turns to groove 3-1.The manufactured materials of runner Flow-rate adjustment bolt 3 is SKD61, and heat treatment hardness requires to reach 48～52HRC.
In mold injection production process, can by inner hexagon spanner, from die joint, carry out flow adjustment being assembled under the state of mould, the Flow-rate adjustment when being applicable to mould and carrying out die trial.While using in a mould with multi-cavities, runner Flow-rate adjustment bolt 3 not only can carry out flow-control, can also cut off or reclose the flow of melt that flows to specific die cavity.While using in the special-shaped multi-cavity mold of a mould, runner Flow-rate adjustment bolt 3 can be realized flow adjusting pin and two kinds of functions of runner king pin.
Compare with runner Flow-rate adjustment pin in the past, runner Flow-rate adjustment bolt 3 is installed more convenient, can regulate by changing the height of bolt the flow of runner, and two template dies, three template dies are all applicable, and flow passage side, discharging push pedal side all can be installed.Installing hole processing dimension to runner Flow-rate adjustment bolt 3, sets suitable accuracy tolerance, in order to avoid produce burr.Be applicable to runner flow and adjust purposes, can not stop up runner completely, adopt the runner Flow-rate adjustment bolt 3 larger than width of flow path size more effective.
Claims (2)
1. flow channel of injection die flow control device, by solid plate (1), runner (2), runner Flow-rate adjustment bolt (3) and moving platen (4), formed, described runner (2) is located between solid plate (1) and moving platen (4) and forms die joint, it is characterized in that: described moving platen (4) is provided with runner Flow-rate adjustment bolt (3).
