Through the runner turns to the round pin and the common cooperation of moving valve, and production perhaps can the coproduction alone respectively can to make three kinds of products, adjusting device compact structure, it is with the obvious advantage, can help the customer to acquire high -quality mould with lower fund and time cost to realize lower product unit price, obtain bigger market and geng duo's profit.
Description
Technical field
The utility model relates to a kind of plasthetics manufacture field, particularly relates to for the runner of a multi-cavity mold and lays adjusting device.
Background technology
Plastic material is a kind of conventional organic material, is extensively incorporated in electronic apparatus and other digital equipment fields. Injection mo(u)lding be heated melt material inject die cavity by high pressure, after cooling curing, obtain the method for products formed. Injection mold should be considered a cavity per mould or a multi-cavity mold, need to design according to cavity layout. Multiple product uses mold injection molding need to open many molds at present, or use hot flow path, has yet and use large mold to go the scheme realizing, but these a few class scheme economy is not good, the mould delivery time is all longer, cannot meet the demand of market to economy and time. Meanwhile, existing scheme is had relatively high expectations to Die & Mold Manufacturing Companies, and the manufacture to mould itself and management and control all propose higher requirement. In addition, the maintenance difficulties in this class mould later stage is larger, convenience deficiency.
When 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 fill bad, weld mark obviously, the injection defect of bubble, buckling deformation, Density inhomogeneity, the excessive even lack of fill of internal stress. While selecting a mould abnormity multi-cavity mold, 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. In addition, a mould abnormity multi-cavity mold is also difficult to realize the selective injection moulding of die cavity.
For solving problems, Chinese patent 201320666576.2, flow channel of injection die flow control device is provided, formed by solid plate (1), runner (2), runner Flow-rate adjustment bolt (3) and moving platen (4), 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). The utility model structure, 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 use 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 use 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. But, using the two kinds of products of injection mold injection moulding simultaneously that comprise described mechanism, cannot realize for the requirement that requires three kinds of injecting products of injection moulding.
Summary of the invention
For solving the problem of above-mentioned existence, the purpose of this utility model is to provide a kind of runner for a multi-cavity mold to lay adjusting device.
For achieving the above object, the technical solution of the utility model is:
Runner for a multi-cavity mold lays an adjusting device, comprises left side and right-hand part, and described left side and described right-hand part are centrosymmetric about cold runner, it is characterized in that, described left side is contained:
One runner king pin, for cylindric, described runner king pin oral area is provided with " fourth " font runner of threeway;
Four classification runners, the orthogonal described runner king pin oral area outside that is arranged at, wherein three classification runners lead to respectively the die cavity of the first product, the second product, three products, and another classification runner is communicated with the cold runner of mould;
Two moving valves, are block structure, and between classification runner and die cavity, described moving valve upper surface is provided with a groove, and the size of described groove is identical with classification runner.
Again, described runner king pin is also provided with a base, and runner king pin can carry out 360 ° of rotations on base.
Separately have, described moving valve can be moved in the direction of vertical staged runner. And when described runner king pin is communicated with cold runner and classification runner, the groove of moving valve is communicated with classification runner, unimpeded between cold runner and classification runner, the product that is positioned at corresponding classification runner carries out injection moulding; The groove of moving valve leaves this position, between cold runner and classification runner, blocks, and the product that is positioned at corresponding classification runner does not carry out injection moulding; Described runner king pin is not communicated with cold runner and classification runner, and the product that is positioned at corresponding classification runner does not carry out injection moulding.
Meanwhile, described classification runner is straight tube.
The beneficial effects of the utility model are:
A kind of runner for a multi-cavity mold that the utility model provides lays adjusting device, be provided with runner king pin and moving valve, by the common cooperation of described runner king pin and moving valve, can make three kinds of products produce separately respectively or can produce simultaneously, described adjusting device compact conformation, with the obvious advantage, can help client to obtain the mould of high-quality with lower fund and time cost, thereby realize lower product unit price, obtain larger market and more profit.
