Abstract
The utility model discloses the low pressure casting water-cooled bed die of a kind of improvement, including bed die, water annulus, cooling water block, technical cooling boss and Graphite pad, bed die arranges technical cooling boss, and technical cooling projection width is set to 30mm, arranges groove on technical cooling boss, technical cooling boss is divided into two by groove, recess width is more than 15mm, and cooling water block is fitted with Graphite pad, and Graphite pad is annulus, width is 25mm, and thickness is 2mm.This utility model is obviously improved for finish turning and polishing class wheel product presentation quality, can effectively reduce bed die temperature, improve wheel surface quality.And verified by batch production, water-cooling process is easy to control and implement, it is ensured that substantially increase qualified casting while the consecutive solidification of foundry goods.
Description
Technical field
This utility model relates to a kind of mould, particularly relates to a kind of low pressure casting water cooling mould for aluminum wheels.
Background technology
Along with the variation day by day of the aesthetic requirement of wheel outward appearance and apparent condition, complication, therefore to Foundry Production work
Skill controls to have higher requirement.Especially surface finish turning and polishing class wheel product in low pressure casting, if Foundry Production
Middle improper process control will add at follow-up machine and runs into spoke surface pinholes class defect in surface treatment process, ultimately results in product
Product are scrapped, and cause the huge waste of enterprise's production cost.
Spoke is as Feeding channel, and in casting process, hot and cold control is particularly important, how to ensure the overall one-tenth smoothly of wheel
On the basis of type, improving and eliminating the surface defect of particular appearance state becomes an important technique problem.
Summary of the invention
This utility model is for above-mentioned production problem, it is provided that the low pressure casting water-cooled bed die of a kind of improvement, can guarantee that wheel
Overall casting smoothly, also can reduce bed die local temperature simultaneously and improve finish turning, the surface quality of polishing class wheel.
This technical scheme is: the low pressure casting water-cooled bed die of improvement, cold including bed die, water annulus, cooling water block, technique
But boss and Graphite pad.Bed die arranges technical cooling boss, limits cooling by water region and plays the effect of Local cooling bed die,
Avoid due to the feeding to other positions of the water-cooled intensity big obstruction spoke, make foundry goods produce defect.
Technical cooling projection width is set to 30mm.For ensureing that spoke zone line Feeding channel is not directly cooled,
Arranging groove on technical cooling boss, technical cooling boss is divided into two by groove, and recess width is more than 15mm.
Cooling water block is loop configuration, assembles with technical cooling boss.Water annulus is arranged in cooling water block, Inlet and outlet water
Mode is two to enter scene 2, two semicircle water channels of Milling Machining, and the most through between water channel, finally water channel is blocked up sealing dead.
Cooling water block and Graphite pad are fitted, then the fastening inside and outside cooling water block and Graphite pad and bed die being passed through
It is bolted together, it is ensured that cooling water block and the levelness of Graphite pad, more conducively with the form dress of plane between three
Join the cooling effect needed for realization.Graphite pad is annulus, and width is 25mm, and thickness is 2mm.
This utility model is obviously improved for finish turning and polishing class wheel product presentation quality, can effectively reduce bed die temperature
Degree, improves wheel surface quality.And verified by batch production, water-cooling process is easy to control and implement, it is ensured that the order of foundry goods
Qualified casting is substantially increased while solidification.

1. spoke in figure, 2. bed die, 3. technical cooling boss, 4. Graphite pad, 5. cooling water block, 6. bolt,
7. water annulus, 8. water inlet pipe and water outlet pipe.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in fig. 1, the low pressure casting die of improvement, including bed die 2, water annulus 7, cooling water block 5, technical cooling
Boss 3 and Graphite pad 4.
The effect of Local cooling bed die 2 is played, it is to avoid due to water-cooled intensity big obstruction spoke 1 for controlling cooling by water region
Feeding to other positions, makes foundry goods produce defect.For bed die 2 spoke 1 appearance surfaces, pin hole class defective locations easily occurs
Place, design technology cooling boss 3, depending on technical cooling boss 3 circumference scope is according to spoke 1 width, its width is 30mm.
For ensureing that spoke 1 zone line Feeding channel is not directly cooled, Milling Machining groove is needed to make technical cooling boss 3 be divided into two, groove
Width should be more than more than 15mm as far as possible.
Making for ease of batch machining, Graphite pad 4 is circular ring structure, and its width of standardization is 25mm, and thickness is 2mm.
Graphite pad 4, as cooling medium, has good heat conductivity, bed die 2 and the derivation of spoke 1 heat is taken away by it.
Effectively cooling down for realizing water-cooled, cooling water block 5 is loop configuration, uses concave structure matching bottom mould 2
Technical cooling boss 3.Water annulus 7 is arranged in cooling water block 5, and Inlet and outlet water mode is two to enter scene 2, two semicircles of Milling Machining
Shape water channel, and the most through between water channel, finally water channel is blocked up sealing dead.
For ensureing the levelness of cooling water block 5 and Graphite pad 4, more conducively assemble with the form of plane between three and realize
Required cooling effect.It is embodied as fitting Graphite pad 4 with bed die 2, then will cooling water block 5 and Graphite pad 4 and bed die 2
Fastening bolt 6 inside and outside by links together.
