Abstract
The utility model discloses a runner structure for multiple cavities. The runner structure comprises an upper runner plate and a low runner plate facing to the upper runner plate, wherein, a runner is arranged between the upper and the lower runner plates; the runner comprises a first runner and a second runner; and the first runner and the second runner are distributed on a joint surface of the upper and the lower runner plates in a central symmetrical manner. The runner structure has the technical effects that through the runner structure disclosed by the utility model, rubber can be injected to multiple cavities at the same time, the production efficiency is high, and the working hours are saved.
Description
Technical field
This patent relates to a kind of mould, relates in particular to a kind of flow passage structure that is used for many types of chamber.
Background technology
Injection mold is an important process equipment of producing various industrial products; Along with plastic mould design industry developing rapidly and plasthetics aviation, boat too, the applying of industrial departments such as electronics, machinery, boats and ships and automobile; Product is to the requirement that requires increasingly high, traditional plastic mould method for designing can't adapt to model change and improve the quality of mould.The computer aided engineering technology become these weak links in plastic cement products exploitation, mould design and the product processing the most effectively by way of.
Mould design and manufacturing and plastic processing have substantial connection.The success or failure of plastic processing depend on mould design effect and mould workmanship to a great extent, and Design of Plastic Mould are designed to the basis with correct plastic products.
The structural element that Design of Plastic Mould will be considered has:
1. die joint, the contact surface that promptly die and punch cooperatively interact during mould closes.Selecting of its position and form receives the influence of factors such as article shape and outward appearance, wall thickness, forming method, after-processing technology, mould-type and structure, release method and shaping machine structure.
2. running gate system promptly by the feeding-passage between injection machine nozzle to the die cavity, comprises sprue, runner, cast gate and cold slug well.Particularly gate location selected should help molten plastic and under the good flow state, be full of die cavity, and the solid-state runner and the cast gate cold burden that are attached on the goods are easy in mould, eject and remove when die sinking.
3. plastic shrink rate and each item factor of influencing product's dimensional precision are like mould manufacturing and rigging error, die wear etc.In addition, when design compression mould and injection mould, go back the technology of considered make-up machine and the coupling of structural parameters.Extensive use Computer-aided Design Technology in Design of Plastic Mould.
The utility model content
This patent technical problem to be solved provides a kind of flow passage structure that is used for many types of chamber, has higher production efficiency, practices thrift man-hour.
To achieve these goals; This patent provides a kind of flow passage structure that is used for many types of chamber; Comprise a upper reaches guidance tape and in the face of the dirty guidance tape of said upper reaches guidance tape; Be provided with runner between said upper reaches guidance tape and the said dirty guidance tape, said runner comprises the first flow and second runner, and the said first flow and second runner center on the composition surface of said upper reaches guidance tape and said dirty guidance tape is symmetrically distributed.
The above-mentioned flow passage structure that is used for many types of chamber, said first flow comprise three first branch flow passages, and said three first branch flow passages are intersected in one first hand-hole.
The above-mentioned flow passage structure that is used for many types of chamber, said second runner comprises three second branch flow passages, said three second branch flow passages are intersected in one second hand-hole.
The above-mentioned flow passage structure that is used for many types of chamber; The end that said first branch flow passage deviates from said first hand-hole be provided with one be used to connect die cavity first-class inlet, the end that second branch flow passage of telling deviates from said second hand-hole be provided with one be used to connect die cavity second inflow entrance.
The above-mentioned flow passage structure that is used for many types of chamber, the diameter of said first-class inlet are less than the diameter of said first hand-hole, and the diameter of said second ostium is less than the diameter of said second hand-hole.
The technique effect of this patent is: through the flow passage structure of this patent, can carry out injecting glue to a plurality of die cavities simultaneously, have higher production efficiency, practice thrift man-hour.
Description of drawings
Fig. 1 is a this patent upper reaches guidance tape sketch map;
Fig. 2 is the dirty guidance tape sketch map of this patent;
Fig. 3 is used for the sketch map of many cavity plate for the flow passage structure of this patent.
The specific embodiment
Below, in conjunction with accompanying drawing this patent is done further explanation.
Please refer to Fig. 1 and Fig. 2, Fig. 1 is a this patent upper reaches guidance tape sketch map, and Fig. 2 is the dirty guidance tape sketch map of this patent.A kind of flow passage structure that is used for many types of chamber; Comprise a upper reaches guidance tape and in the face of the dirty guidance tape of upper reaches guidance tape; Be provided with runner between upper reaches guidance tape and the dirty guidance tape; Runner comprises the first flow and second runner, and the first flow and second runner center on the composition surface of upper reaches guidance tape and dirty guidance tape is symmetrically distributed.
Please refer to Fig. 3, Fig. 3 is used for the sketch map of many cavity plate for the flow passage structure of this patent.First flow comprises three first branch flow passages, and three first branch flow passages are intersected in one first hand-hole.Second runner comprises three second branch flow passages, and three second branch flow passages are intersected in one second hand-hole.The end that first branch flow passage deviates from first hand-hole be provided with one be used to connect die cavity first-class inlet, the end that second branch flow passage of telling deviates from second hand-hole be provided with one be used to connect die cavity second inflow entrance.The diameter of first-class inlet is less than the diameter of first hand-hole, and the diameter of second ostium is less than the diameter of second hand-hole.
The flow passage structure of this patent also can comprise a plurality of branch flow passages, and the number of branch flow passage and die cavity number coupling like this can be simultaneously to a plurality of die cavity injecting glues.In addition, through regulate hand-hole and with the diameter proportion of the corresponding inflow entrance of this hand-hole, can also control the flow velocity of melten gel.
Though oneself discloses this patent as above with preferred embodiment, this patent is not to be defined in this.Any those skilled in the art in spirit that does not break away from this patent and scope, all can do various changes and modification, so the protection domain of this patent should be as the criterion with claim institute restricted portion.
