Abstract
The utility model relates to an upper and lower die PCD (Poly Crystal Diamond) column water cooling structure of a low-pressure casting mold. Vertical cold water holes are drilled at the positions of upper and lower dies of each PCD column corresponding to an aluminum alloy wheel respectively; taper pipes are arranged on the cold water holes through threaded engagement; each taper pipe is coaxially communicated with a water inlet pipe; the taper pipe is radially communicated with a water outlet pipe. The water cooling structure can effectively solve the problems of shrinkage cavity and porosity and low yield caused by greater and non-uniform wall thickness at the PCD column position of the mold and poor cooling in the aluminum alloy wheel casting production; compared with the conventional air cooling mold, the water cooling structure has the advantages that the mold cooling speed is greatly improved and the hub shaping time is shortened; compared with a water cooling mold using a water cooling tank, the water cooling structure has the advantages that the defects of shrinkage cavity and porosity of a product caused by non-uniform wall thickness but same cooling degree of the PCD column and a back cavity of the mold are avoided, the mold machining cost is also reduced, and the water cooling structure is simple and practicable.
Description
Technical field
The utility model belongs to mould applications, relates to the cooling of aluminum-alloy wheel casting mould, the upper and lower mould PCD post of especially a kind of low-pressure casting die of aluminium alloy wheel position cooling.
Background technology
In the aluminum-alloy wheel casting industry, the cooling of cast blank is a very crucial technology, and this section processes is improper is easy to cause the cast blank shrinkage cavity shrinkage porosity of producing, and causes and scraps.Present stage China aluminum-alloy wheel in casting process because Yu Bei chamber, PCD post position wall unevenness is even, and near Lv Ye center pouring position, temperature is high than other positions, more difficult cooling and difficult control, being subjected to this to affect cast blank cooling velocity and cooling gradient when cooling can not be controlled preferably, easily produce and scrap, the performance of cast article and yield rate are difficult to guarantee.
Summary of the invention
The purpose of this utility model is to make up the deficiencies in the prior art part, and the upper and lower mould PCD post water-cooling structure of a kind of good cooling results, low pressure casting die that cooling effectiveness is high is provided.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of upper and lower mould PCD post water-cooling structure of low pressure casting die, in the corresponding aluminum-alloy wheel upper and lower mould of each PCD post position, drill respectively vertical cold water hole, screw-threaded engagement is equipped with Taper Pipe on this cold water hole, on each Taper Pipe, equal coaxial communication is installed into water pipe, in the radial communication of Taper Pipe, outlet pipe is installed.
And, on the Taper Pipe in cold water hole, coaxially with water inlet pipe, be communicated with cold water pipe is installed.
Advantage of the present utility model and beneficial effect are:
1, this water-cooling structure is the part change on the pressure common casting mould structure, in upper and lower mould PCD post position, bore cold water hole, adopt the taper pipe thread connected mode, by the quick cooling die PCD post of water-cooled new technology position, improve the bad problem of cast blank moulding, be skillfully constructed, design science, workable.
2, this water-cooling structure can effectively solve in the aluminum-alloy wheel Foundry Production due to thicker and inhomogeneous, the cooling bad generation shrinkage cavity shrinkage porosity of mould PCD post position wall thickness, cause the problem that yield rate is low, compared to the air-cooled mould of tradition (for Zuan Feng hole, PCD post position), greatly improve mold cools down speed, shortened the wheel hub molding time; Compared to the water cooling mold that adopts water-cooling groove, mould PCD post and back of the body chamber the same product shrinkage cavity and the shrinkage defect caused of degree of catching a cold because wall unevenness is even have namely been avoided, reduced again the Mould Machining cost, simple in structure, practical, improve widely performance and the yield rate of cast blank, saved cost, improved efficiency.
The accompanying drawing explanation
Fig. 1 is that the utility model partly cuts open schematic diagram at the mounting structure of low pressure casting die;
Fig. 2 is the upward view (part) of Fig. 1.
The specific embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of upper and lower mould PCD post water-cooling structure of low pressure casting die, its mounting structure is referring to Fig. 1, at the upper and lower mould 1(of each PCD post of corresponding aluminum-alloy wheel the present embodiment accompanying drawing, being depicted as counterdie) position drills respectively vertical cold water hole 2, screw-threaded engagement is equipped with Taper Pipe 3 on this cold water hole, on each Taper Pipe, equal coaxial communication is installed into water pipe 5, on this Taper Pipe in cold water hole, coaxially with water inlet pipe, be communicated with cold water pipe 4 is installed, in the radial communication of Taper Pipe, outlet pipe 6 is installed.
Because aluminum-alloy wheel is uniform on diametric plane, be shaped with a plurality of PCD posts, therefore uniformly in the upper and lower mould position of corresponding PCD post be shaped with a plurality of cold water holes, shown in the present embodiment accompanying drawing 2, be five.
At the bottom of the hole of each cold water hole, be circular hole, and guarantee apart from counterdie cavity surface minimum wall thickness (MINI W.), to be not less than 15mm at the bottom of hole; Under the principle that as far as possible guarantees same pitch circle, in the position of distance counterdie apopore 15mm, thermometer hole is set, facilitate Measurement die temperature in its use procedure, to reach temperature control effect.In the foundry production of mould, by upper and lower mould water flowing, according to actual conditions, water yield and water flowing time are adjusted, made it the effect that reaches optimum.
At upper and lower mould, can adopt series connection/parallel way to connect for the outlet pipe of each Taper Pipe of answering PCD post position to install and water inlet pipe: the mode that is connected in series namely enters water by Taper Pipe one side, by side one side opening water outlet, between Taper Pipe, interconnects circulation one circle; Parallel way namely enters water by a water inlet pipe, by the water inlet pipe of each Taper Pipe, is connected respectively, then by the side of Taper Pipe, connects outlet pipe and form circulation in parallel.
