Abstract
The invention discloses an experimental apparatus for simulating a cooling system of a mold, which is characterized in that the cooling system is made into an independent module and then inserted into the mold; metal powder is filled in the mold by utilizing the fluidity of the metal powder, so that one mold changes a plurality of cooling systems as needed, then the problems of the cooling systems of a hot stamping mold and an injection mold are discovered and researched, and accuracy of simulation and analogue results of the cooling system of the mold is verified.
Description
Technical field
Patent of the present invention relates to a kind of experimental provision of simulating mold cooling system, especially is applicable to the cooling system of hot stamping die and injection mold.
Background technology
Automotive light weight technology is promoting the fast development of super-high strength steel hot technology.Hot stamping die is the core component in the drop stamping production line, and its effect is in the hot forming process, finishes high-temperature steel plate and is shaped and Quenching Treatment, and therefore need to process cooling pipe in mould improves cooling velocity, finishes the martensite transfor mation of heat-punch member.Therefore the cooling of mold temperature and dwell time take the time more than 1/2 in the production process in the industrial production, improve cooling velocity and be the effective means of enhancing productivity and reducing production costs.In addition, be subjected to the restriction of mould structure and heat-punch member shape, cooling pipe can not be evenly arranged in the mould, thereby causes quenching velocity inhomogeneous, affect heat-punch member forming accuracy and performance, therefore be badly in need of carrying out mold cools down pipeline and the research of cooling velocity optimal design.
In the injection mold, it is calculated that 95% of molten plastic heat is taken away by cooling system, inject time, dwell time and cool time account for more than 3/4 of whole injection cycle, thereby cooling system is determining injection molded efficient.And good cooling system can realize that molten plastic evenly cools off, and reduces the buckling deformation of injection-molded item, improves dimensional accuracy, improves surface quality, improves combination property, thereby also extremely important to the research of injection mould cooling system.
Development along with computer technology, the researcher can change arbitrarily the cooling system parameter by the CAD modeling, carry out the aspect researchs such as temperature field, flow velocity of cooling system by CAE, the research paper of the analog simulation aspect of many hot stamping dies and injection mould cooling system therefore occurred.Yet in the reality, because the Mould Machining somewhat expensive, the cooling system parameter is more, and is complex-shaped, is difficult for the difficult problems such as processing, so it is less to carry out the research of mold cooling system experiment.Yet theoretical research need to be tested to prove, and only have experiment could verify analog simulation result's accuracy, so the experimental study of mold cooling system also need be caught up with theoretical paces.
Summary of the invention
In order to carry out the experimental study of mold cooling system, overcome the deficiency that a mold can only be processed a cover or less cooling system, patent of the present invention provides a kind of experimental provision of simulating mold cooling system, and this device is any conversion cooling system as required.
Patent of the present invention solves the technical scheme that its technical problem adopts: process base plate according to die face, in base plate thickness remains on more among a small circle (about 10mm), at base plate both sides resting guide, be assembled into a housing, cooling pipe, guide plate, spacer are dressed up cooling system by the demand der group, cooling system is inserted in the housing, insert metal dust, utilize the flowability of metal dust, enclosure interior is enriched, the housing seal of again metal dust being enriched is assembled into the hot stamping die or the injection mold that contain cooling system.
When changing cooling system, open housing, remove metal dust, take out and the dismounting cooling system, re-assembly as requested new cooling system, new cooling system is inserted in the housing, insert metal dust, utilize the flowability of metal dust, enclosure interior is enriched, the housing seal of again metal dust being enriched is assembled into the hot stamping die or the injection mold that contain new cooling system.
According to demand, change guide plate, spacer or cooling pipe, can realize that a secondary mould changes multiple cooling system as required, and then find and problem that the research cooling system occurs the accuracy of checking cooling system emulation and analog result.
