Abstract
The invention discloses an injection mold. The injection mold has an upper mold and a lower mold. The upper mold and the lower mold cooperate with each other to form a middle injection molding cavity. The middle of the upper mold has an injection molding opening. A pipeline layer is arranged inside the upper mold and the lower mold. The pipeline layer surrounds the injection molding cavity and is uniformly distributed. The pipeline layer has pipelines which communicate with each other. One end of the pipeline layer is connected with an input main, and the other end of the pipeline layer is connected with an output main. During moulding of an injection-molded part, the inside of the injection mold can be effectively cooled. Thus, the inside structure of the mold is protected, structural distortion of the mold is avoided, quality of the injection-molded part is enhanced, resources are saved, and production cost is reduced.
Description
Technical field
The present invention relates to a kind of injection mold, the injection mold of cooling pipe device is especially housed.
Background technology
Moulding adopts injection mold to carry out injection molding usually, the structure of mould is generally have upper and lower two modules, injection moulding cavity is formed in the middle of after the airtight combination of upper die and lower die, owing to adding the plastic pellet of melting during cast, easily make the malformations such as mold cores, be therefore necessary to accelerate cool and make moulding shaping sooner after casting complete.Also having some cooling systems at present, is arrange some through holes at mould inside, then inject water in through-holes and make it cooling, but the cooling effect of this structure is bad, can make cooling point skewness, probably makes moulding be out of shape, adds scrappage.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of injection mold, this mould inside is equipped with cooling pipe device, moulding can be made to accelerate when shaping and uniform cooling, core rod is made not to be in the condition of high temperature for a long time, avoid mould inside malformation, improve the quality of moulding, reduce scrappage, saving resource and reduction production cost.
For solving the problems of the technologies described above, injection mold of the present invention has upper die and lower die, described upper die and lower die coordinate the injection moulding cavity in the middle of composition, in the middle of described patrix, there is injection hole, it is characterized in that: the inside of described upper die and lower die has pipe layers, described pipe layers is centered around around injection moulding cavity, and pipe layers has the pipeline interconnected, pipe layers one end connects input total pipeline, and the other end of pipe layers connects delivery trunk road.
Described pipe layers can be netted.
Described pipe layers is evenly distributed on around injection moulding cavity.
Described pipeline is can be columned.
Described pipeline is flat-shaped.
After adopting such structure, cooling fluid can be flowed into from input total pipeline when moulding is shaping, cooling fluid is by carrying out heat exchange when pipe layers, then cooling fluid flows out from delivery trunk road, the internal structure of mould can be lowered the temperature fast, avoid mould inside structure deformed damaged under long high temperature, and due to pipe layers be equally distributed around injection moulding cavity, so not easily make moulding produce the quality problems such as distortion.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the schematic diagram of the embodiment of injection mold of the present invention.
In figure, 1 is input total pipeline, and 2 is delivery trunk roads, and 3 is pipelines, and 4 is injection holes, and 5 is patrixes, and 6 is counterdies, and 7 is injection moulding cavitys, and 8 is pipe layers.
Detailed description of the invention
Injection mold according to Fig. 1 has patrix 5, counterdie 6, in the middle of patrix 5, there is injection hole 4, patrix 5 and the closed rear middle formation injection moulding cavity 7 of counterdie 6, have pipe layers 8 in the inside of patrix 5 and counterdie 6, this pipe layers 8 is centered around injection moulding cavity 7 around, and pipe layers 8 has the pipeline 3 be interconnected, pipe layers 8 while be equipped with input total pipeline 1, another side is equipped with delivery trunk road 2.
During use, the plastics of high-temperature fusion flow into injection moulding cavity 7 from injection hole 4, and when injection moulding completes, flow into cooling fluid from input total pipeline 1, cooling fluid is by taking away heat of high temperature during pipe layers 8, and then cooling fluid flows out from delivery trunk road 2.
Above-described embodiment does not limit the present invention in any form, the technical scheme that the mode that all employings are equal to replacement or equivalent transformation obtains, and all drops in protection scope of the present invention.
