Abstract
The utility model relates to a double-heat-insulation hub die-casting mould. The double-heat-insulation hub die-casting mould comprises additional heat insulation cotton, window heat insulation cotton and annular grooves, wherein the additional heat insulation cotton is fixed on wheel arms in a wrapped mode, the window heat insulation cotton is arranged above the additional heat insulation cotton and located on the window position between every two adjacent wheel arms, and the annular grooves are formed in the cold joint parts of the wheel arms and wind in the circumferential direction. Annular heat insulation cotton is fixed in the annular grooves. For narrow wheel arms and thin wheel types, the additional heat insulation cotton and the window heat insulation cotton can effectively relieve the influence of low temperature in winter on a die-casting process; the turned annular groove structure can weaken the heat absorption capacity of die steel at the position; one layer of annular heat insulation cotton is additionally arranged on the annular groove, and then a double-heat-insulation structure is formed. The temperature loss at the cold joint parts of the middles of the wheel arms is effectively lowered, and therefore the effective implementation of the process is guaranteed. For the narrow wheel arms and thin wheel types, after the double-heat-insulation structure is additionally arranged, the temperature loss at the cold joint parts of the middles of the wheel arms is effectively lowered, and therefore it is guaranteed that the temperature at the cold joint parts of the wheel arms and the mould temperature gradient are more reasonable.
Description
Technical field
The utility model relates to wheel hub manufacturing technology field, is specifically related to a kind of wheel hub structure of cast die.
Background technology
Narrower and the thinner or narrower less wheel type of spoke for spoke, in the middle of spoke, the cold joint phenomenon of outside left is serious partially, affected obviously by ambient temperature, affect cast blank order cooling, cause spoke back of the body chamber shrinkage porosite, technique is adjusted difficulty, and therefore qualified casting is low and production efficiency is lower.
Summary of the invention
The utility model, in order to overcome the deficiency of above technology, provides a kind of wheel hub die casting that possesses two insulation constructions.
The utility model overcomes the technical scheme that its technical problem adopts:
This pair of insulation wheel hub die casting, comprise hold the thermal insulation cotton of being fixed on spoke, be arranged at thermal insulation cotton top and between every two adjacent spokes the window's position window heat-preservation cotton and be arranged on the cold joint of spoke position and along the circumferential direction around cannelure, in described cannelure, be fixed with ring-type heat-preservation cotton.。
In order further to improve spoke insulation, also comprise two insulation holes that are arranged on each spoke of patrix back of the body chamber, described each insulation is provided with heat-preservation cotton in hole.
The beneficial effects of the utility model are: thermal insulation cotton and window heat-preservation cotton be the narrower and thinner type of taking turns for spoke, can effectively reduce the impact of winter low temperature on extrusion process, the structure of turning processing cannelure, can weaken this position mould steel heat absorption capacity, on cannelure, locate again to add again one deck ring-type heat-preservation cotton, form two insulation constructions.Effectively reduce cold joint position, spoke middle part temperature and scatter and disappear, ensured effective enforcement of technique.Narrower and thinner the wheel after the two insulation constructions of type increase to spoke, effectively reduces cold joint position, spoke middle part temperature and scatters and disappears, and has ensured that the cold joint of spoke position temperature and mold temperature gradient are more reasonable, is convenient to technique adjustment, reduces foundary loss rate, enhances productivity.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model cannelure portion structure schematic diagram;
In figure, 1. the cotton 2. window heat-preservation cotton 3. of thermal insulation are incubated hole 4. cannelures.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, accompanying drawing 2, the utility model is described further.
This pair of insulation wheel hub die casting, comprise hold the thermal insulation cotton 1 of being fixed on spoke, be arranged at cotton 1 top of thermal insulation and between every two adjacent spokes the window's position window heat-preservation cotton 2 and be arranged on the cold joint of spoke position and along the circumferential direction around cannelure 4, in cannelure 4, be fixed with ring-type heat-preservation cotton.Thermal insulation cotton 1 and window heat-preservation cotton 2 be the narrower and thinner type of taking turns for spoke, can effectively reduce the impact of winter low temperature on extrusion process, the structure of turning processing cannelure 4, can weaken this position mould steel heat absorption capacity, on cannelure 4, locate again to add again one deck ring-type heat-preservation cotton, form two insulation constructions.Effectively reduce cold joint position, spoke middle part temperature and scatter and disappear, ensured effective enforcement of technique.Narrower and thinner the wheel after the two insulation constructions of type increase to spoke, effectively reduces cold joint position, spoke middle part temperature and scatters and disappears, and has ensured that the cold joint of spoke position temperature and mold temperature gradient are more reasonable, is convenient to technique adjustment, reduces foundary loss rate, enhances productivity.
Can also carry on the back on each spoke of chamber two insulation holes are set at patrix, each insulation be provided with heat-preservation cotton in hole.Like this, on the basis of original window insulation, increase again spoke insulation, effectively reduced cold joint position, spoke middle part temperature and scatter and disappear, ensured effective enforcement of technique.
