Abstract
The utility model discloses an oil-way system of an injection mold. The oil-way system comprises a template, an oil inlet pipe, an oil outlet pipe, four mold cores and four hollow oil pipes, wherein the mold cores are arranged inside the template; the lower ends of the mold cores are communicated with the oil inlet pipe and the oil outlet pipe; the hollow oil pipes is sleeved with the mold cores with clearance; four oil outlets are formed in the oil outlet pipe; the hollow oil pipes pass through the oil outlet pipe through the oil outlets; oil inlets are formed in the oil inlet pipe; the aperture of the oil inlets is equal to the diameter of the hollow oil pipes; the bottom end of each hollow pipe is connected with the oil inlet pipe through the corresponding oil inlet; a heat-conducting oil hole is formed in the top end inside each mold core. According to the technical scheme, heat-conducting oil enters through the oil inlet pipe, and then enters the hollow oil pipes through the oil inlets; the heat-conducting oil is conveyed from bottom to top under pressure action; the heat-conducting oil is discharged out of the hollow oil pipes through the heat-conducting oil holes in the upper ends of the mold cores; the heat-conducting oil flows along the clearance between the mold cores and the hollow oil pipes, and then enters the oil outlet pipe through the oil outlets to be discharged.
Description
Technical field
The utility model belongs to injection mold temperature control field, relates in particular to a kind of oil piping system of high temperature heat conductive oil importing mould.
Background technology
In precise injection mould, because mould need to keep certain temperature, tend to use automatic die temperature controller.By the oil circuit in the conduction oil medium connecting mold in die heater, make the temperature of mould controlled.Die cavity and the core of general mould all need to arrange oil piping system, comparatively speaking, oil piping system are set in die cavity, relatively convenient.But in core, design oil circuit, but very difficult.
Summary of the invention
In order to address the above problem, the utility model provides a kind of oil piping system for injection mold, thereby it is convenient to make conduction oil import mould.
Adopt following technical scheme: a kind of oil piping system for injection mold for this reason, comprise template, oil inlet pipe, flowline and core, described core is positioned at template, and core lower end is communicated with oil inlet pipe and flowline, it is characterized in that: it also comprises middle dry pipe, described middle dry pipe gap is linked in core, on flowline, be provided with oil outlet, middle dry pipe passes flowline by oil outlet, on oil inlet pipe, be provided with fuel feed hole, the aperture of fuel feed hole equals the diameter of middle dry pipe, and hollow pipeline bottom is connected with oil inlet pipe by fuel feed hole; Core inner tip has a heat conduction oilhole, and the diameter of described heat conduction oilhole is greater than the diameter of middle dry pipe; The aperture of oil outlet is greater than the diameter of heat conduction oilhole.
Further, core bottom offers cannelure, is provided with gasket seal, the thick 0.5mm of described gasket seal Thickness Ratio cannelure in cannelure.
Further, the diameter of middle dry pipe is generally 3mm-5mm, and the diameter of described heat conduction oilhole is than the large 2mm of the diameter of hollow heat-conducting oil pipes; Large 1mm-the 3mm of aperture ratio conduction oil bore dia of described oil outlet.
Further, on oil inlet pipe and flowline, be equipped with joint, described joint is positioned at the interface of oil pipe and template.
By such technical scheme, conduction oil enters by oil inlet pipe, then enters in middle dry pipe by fuel feed hole, under pressure-acting, conduction oil is carried from bottom to top, finally by the heat conduction oilhole of core upper end, conduction oil is discharged to outside middle dry pipe.Conduction oil flows down along the gap between core and middle dry pipe again, enters flowline afterwards by oil outlet, and conduction oil is discharged.The gasket seal of described core bottom can effectively prevent that conduction oil from entering mould inside and causing damage.
