Abstract

The invention relates to the technical field of multiple sprues of plastic products, in particular to a multi-sprue runner system. The multi-sprue runner system comprises N sprues and a runner which communicates all sprues, wherein N sprues are designed according to volume of the product to be filled and a molding process; the runner comprises multiple shunting runners for shunting from the top down; and the N sprues are uniformly distributed on the bottom shunting runner. The multi-sprue runner system can be applied to multi-cavity molds or symmetrically-structured products requiring multiple sprues, in particular to closed barrel-shaped products which are limited by mold structures or processes and therefore cannot adopt X-shaped or annular sprues under. By using the multi-stage shutting runner structure, the self balance of all sprues can be better realized while the runner waste is reduced; therefore, the self balance of pressure and the self balance of temperature are realized.

Description

Many cast gates flow passage system
Technical field
The present invention relates to many cast gates technical field of injection-molded item, relate in particular to a kind of many cast gates flow passage system.
Background technology
At present, for the multi-point mould goods, its runner distributes generally according to the O type, the I type, the H type, X type or their hybrid distributed solve the flow equilibrium problem between each cave, for same goods sometimes because the restriction of other factorses such as mould structure or moulding, must adopt a plurality of cast gates, the runner general using X type or the annular that connect each cast gate reach flow equilibrium, even passing through of having do not waited each gate area to reach the artificial equilibrium, but these are limited by mould structure and moulding process also, can only be used for specific occasions, and circular gate is difficult to remove, and artificial equilibrium's runner also can only just can reach the balance in the ideal under fixing condition of molding.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the technical problem to be solved in the present invention provides a kind of energy can realize the flow of same goods or the many cast gates of each cave goods, many cast gates flow passage system of pressure and temperature balance.
To achieve these goals, technical scheme of the present invention is:
A kind of many cast gates flow passage system, the runner that comprises N cast gate and each cast gate of connection, described a plurality of cast gate is according to the volume of want filled articles and moulding process is required is designed to constant N, described runner comprises the multi-stage diffluence road of shunting from the top down, and N cast gate is evenly distributed on bottom one-level runner.
Further, when N was even number, described runner comprised N/2 level runner; When N was odd number, described runner comprised (N+1)/2 grade runner, and runners at different levels are equipped with diverter branch, and bottom one-level runner is provided with N diverter branch, and N diverter branch is communicated with N cast gate respectively.
Further, each diverter branch equal in length of higher level's runner of N cast gate, the starting point of its projection is positioned at how much mid points of two cast gates of subordinate, the end point is positioned at the point of adjacent two diverter branch of runner at the corresponding levels, the upper level runner is with this type of example again, until 2 of the diverter branch of this grade runner.
Further, the diverter branch of described runners at different levels is planar parallel or parallel in the space.
Further, the diverter branch geometric properties of described runners at different levels is identical and shape is not limit.
The present invention with respect to the beneficial effect of prior art is:
The present invention utilizes multi-stage diffluence road structure, when reducing the runner waste material, can realize the self-balancing of each cast gate well, thereby reach the self-balancing of pressure, temperature, and the running gate system after making is easy to remove than circular gate, it is good to remove back goods apparent mass.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in detail.
Embodiment one, Fig. 1 and Fig. 2 are that 4 points (N is an even number) balance is advanced the embodiment of glue scheme, four cast gates 5 evenly distribute, four total two (4/2=2) up and down of cast gate level runners, top one-level runner is an one-level runner 1, following one-level runner is a secondary runner 2, and secondary runner 2 is provided with four diverter branch 21, and one-level runner 1 is provided with two diverter branch 11; Four diverter branch 21 are communicated with four cast gates 5 respectively, the equal in length of four diverter branch 21, be each cast gate half of combined flow channel length in twos, the starting point of diverter branch 11 projections of one-level runner 1 be arranged in secondary runner 2 adjacent two diverter branch 21 converge mid point, the terminal point of diverter branch 11 projections and one-level runner the point of adjacent two diverter branch 11 converge, link to each other with sprue then, each diverter branch geometric properties of runners at different levels is identical.
Embodiment two, Fig. 3 and Fig. 4 are that 5 points (N is an odd number) balance is advanced the embodiment of glue scheme, five cast gates 5 evenly distribute, combination in twos, form three grades of [(5+1)/2] runners up and down, be respectively one-level runner 1, secondary runner 2 and 3, three grades of runners 3 of three grades of runners and be provided with five diverter branch 31, secondary runner 2 is provided with four diverter branch 21, and one-level runner 1 is provided with two diverter branch 11; The cast gate 5 that the starting point of diverter branch 31 projections of three grades of runners is communicated with it overlaps, the terminal point of diverter branch 31 projections overlaps with how much mid points of adjacent two cast gates 5, the equal in length of five diverter branch 31, the starting point of diverter branch 21 projections of secondary runner 2 is positioned at how much mid points of two diverter branch 31, the terminal point of diverter branch 21 projections is positioned at adjacent two diverter branch, 21 points at the corresponding levels, diverter branch 11 The initial segment of one-level runner 1 and the diverter branch 21 of secondary runner 2 are roughly the same, the terminal point of its projection converges with another runner of layer at the corresponding levels, link to each other with sprue then, each diverter branch geometric properties of runners at different levels is identical.
Many cast gates of the present invention flow passage system solves the restriction because of factors such as mould structure or moulding, can not adopt traditional O type, I type, H type, X type or their mixed type to realize the flow equilibrium problem of multi-point mould goods or many cast gates goods of balance, make and not only can in the plane but also can spatially realize the runner self-balancing, thereby realize each cast gate flow between same goods or the many caves goods, pressure, the theoretic balance of temperature, and the running gate system after making is easy to remove, and it is good to remove back goods apparent mass.
Above embodiment only is used to technical scheme of the present invention is described, is not intended to limit; Although the present invention is had been described in detail with reference to preferred embodiment; those of ordinary skill in the field are to be understood that; still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present invention; and not breaking away from the spirit of technical solution of the present invention, it all should be encompassed in the middle of the technical scheme scope that the present invention asks for protection.
