Abstract
The invention discloses an injection mold cold runner casting system structure. The injection mold cold runner casting system structure comprises a main runner, a first grade sub-runner, a first grade cool material well, concealed type casting gates, second grade main runners, a second grade sub-runner, a third grade sub-runner, a side gate and a second grade cool mineral well; a first grade concealed type casting system is formed by the main runner, the first grade sub-runner, the first grade cool material well and the concealed type casting gate; a side gate casting system is formed by the second grade main runners, the second grade sub-runner, the third grade sub-runner, the third grade sub-runner, the side gate and the second grade cool mineral well; the first grade concealed type casting system and the side gate casting system are arranged on one side of a movable die; a low-cost two-plate mold structural mode is adopted, the casting gate is formed in the inner side of a product, by the adoption of a casting system mode formed by combining multiple casting gates, injection material flow of an injection molding machine is guided into the side gate inside the product to conduct casting on a mold cavity, it is guaranteed that injection without gate casting traces on the appearance of the product in product injection does not exist by adopting the two-plate mold structural mold, the appearance completeness of the product is protected, the runner structure design is novel, the use is convenient, the work is stable, and safety and reliability can be achieved.
Description
Technical field
The present invention relates to mould structure design field, be specially a kind of injection mold cold runner injection system structure.
Background technology
During molding injection mo(u)lding, offering of cast gate has considerable influence to product appearance, be generally the presentation quality ensureing product, the available design form of cast gate can select spot pouring mouth form or fan-shaped flake side gate form, but, above-mentioned gate form leaves injection moulding vestige more or less all the time in product appearance, can not thoroughly deal with problems, and, comparatively speaking, offering of spot pouring mouth need in conjunction with three board mold structures, die manufacturing cost sharply increases, fan-shaped flake side gate then needs to increase cast gate finishing process, add production cost, Given this, the invention provides a kind of injection mold cold runner injection system structure, can need according to the presentation quality of plastic product, avoid offering cast gate in appearance region, but adopt low cost two template die frame mode, cast gate is opened in inside product, the running gate system mode combined by multiple cast gate, injection machine is injected stream and be incorporated into side gate in product, thus die cavity is poured into a mould, ensure that product appearance is without gate vestiges injection moulding, protect the complete appearance of product, flow passage structure is novel in design, easy-to-use, working stability, safe and reliable.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of injection mold cold runner structure, comprises sprue, one-level runner, one-level slag well, sub marine gate, secondary sprue, secondary runner, three fraction runners, side gate, secondary slag well;
Described sprue, one-level runner, one-level slag well, sub marine gate composition one-level Subsidence pouring system; Secondary sprue, secondary runner, three fraction runners, side gate, secondary slag well composition side gate running gate system;
Described one-level Subsidence pouring system, side gate running gate system are opened in dynamic model side;
Described cold runner structure pour into a mould by improvement product presentation quality and adopt a kind of by Design of Runner System new method combined for multiple gate design.
Beneficial effect: a kind of injection mold cold runner injection system structure that the present invention adopts technique scheme to provide; adopt low cost two template die frame mode; cast gate is opened in inside product; the running gate system mode combined by multiple cast gate; injection machine is injected stream and be incorporated into side gate in product; thus die cavity is poured into a mould; when ensure that employing two template die structure mold injecting products, product appearance is without gate vestiges injection moulding; protect the complete appearance of product; flow passage structure is novel in design; easy-to-use, working stability, safe and reliable.
Accompanying drawing explanation
Fig. 1 is a kind of injection mold cold runner of the present invention injection system structure composition schematic diagram;
Fig. 2 is that a kind of injection mold cold runner of the present invention injection system structure is at dynamic model portion schematic diagram;
Fig. 3 is a kind of injection mold cold runner injection system structure of the present invention schematic diagram in die cavity.
Detailed description of the invention
Fig. 1-3 are structure and working principle key diagram of the present invention; As shown in Figure 1, a kind of injection mold cold runner structure, comprises sprue 1, one-level runner 2, one-level slag well 3, sub marine gate 4, secondary sprue 5, secondary runner 6, three fraction runner 7, side gate 8, secondary slag well 9;
Described sprue 1, one-level runner 2, one-level slag well 3, sub marine gate 4 form one-level Subsidence pouring system; Secondary sprue 5, secondary runner 6, three fraction runner 7, side gate 8, secondary slag well 9 form side gate running gate system, as Fig. 1 and shown in composition graphs 2;
Described one-level Subsidence pouring system, side gate running gate system are opened in dynamic model side;
Described cold runner structure pour into a mould by improvement product presentation quality and adopt a kind of by Design of Runner System new method combined for multiple gate design.
When the present invention applies in a mold, operation principle during work is:
Composition graphs 1, shown in Fig. 3, after mould is closed, injection moulding starts, stream sprays into the entry position of sprue 1 epimere from injection molding machine nozzle, be incorporated in one-level runner 2 by sprue 1, entrance cold burden will be filled with in one-level slag well 3, to ensure that subsequent thermal stream can reach and smoothly by sub marine gate 4, stream is by after sub marine gate 4, enter secondary sprue 5, being designed to space, sub marine gate 4 contact position of secondary sprue 5 is large, and its upper end outlet place, discharge area is little, shear and strengthen, thus cause stream to rub herein aggravation, material temperature gets a promotion 5-10 DEG C, stream flows strengthens, then intensification stream enters three fraction runners 7 by secondary runner 6, in three fraction runners 7, stream front end cold front enters secondary slag well 9, thus ensure that follow-up stream is reliably injected and loading mould cavity by side gate 8, side gate 8 then crypticity is opened in inside product, collateral security product appearance is without gate vestiges injection moulding, protect the complete appearance of product.
The present invention can need according to the presentation quality of plastic product; avoid offering cast gate in appearance region; and adopt low cost two template die frame mode; the running gate system mode combined by multiple cast gate; injection machine is injected stream and be incorporated into side gate in product, thus die cavity is poured into a mould, ensure that product appearance is without gate vestiges injection moulding; protect the complete appearance of product, and mould production cost and shorten die manufacturing cycle efficiently.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit, those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
