Abstract
The utility model relates to a mould with insulation riser, including left mould, right mould, left mould and the inside die cavity that is equipped with of right mould junction, the die cavity top is equipped with the neck that contracts, and the neck top of contracting is equipped with the open riser, is equipped with the asbestos board on the inside lateral wall of open riser, and the die cavity middle part is equipped with the blind riser, is equipped with the asbestos board on the lateral wall of blind riser inside, and one side of blind riser is equipped with the core vent, the utility model provides a not thorough problems of feeding at the thick big and thermal center positions of all kinds of aluminum alloy metal mold gravity casting foundry goods, saved the quantity of rising head aluminium material simultaneously, increase substantially technology product rate.
Description
Technical field
The utility model relates to aluminum alloy metal-type gravity casting die technical field, particularly relates to a kind of mould with insulated feeder.
Background technology
Aluminum alloy metal-type gravitational casting foundry goods often there will be in process makes foundry goods easily produce the problem of shrinkage cavity and porosity, draw because of thick large, hot-spot.Use common riser head heat-preserving device cannot solve the difficult problem reaching feeding effect.
Summary of the invention
The utility model is intended to solve the deficiencies in the prior art, and provides a kind of mould with insulated feeder.
The utility model for achieving the above object, by the following technical solutions: a kind of mould with insulated feeder, it is characterized in that, comprise left mould, right mould, left mould and right mould joint inside are provided with die cavity, contracting neck is provided with above die cavity, be provided with open riser above contracting neck, the internal side wall of open riser is provided with asbestos board, is provided with blind riser in the middle part of die cavity, blind riser internal side wall is provided with asbestos board, and the side of blind riser is provided with venting plug.
Described contracting neck is of a size of 5mm ~ 10mm.
The material of described left mould and described right mould is the one in mould steel, gray iron.
Described asbestos board surface scribbles thermal insulation coatings.
The beneficial effects of the utility model are: the utility model solves the halfway problem of feeding of the thick large and heat energy-saving position of all kinds of aluminum alloy metal-type gravitational casting foundry goods, saves the consumption of rising head aluminium material simultaneously, increases substantially product yield.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: the left mould of 1-; 2-asbestos board; The right mould of 3-; 4-open riser; 5-die cavity; 6-blind riser; 7-contracting neck; 8-venting plug; The thick general goal thermal center of 9-foundry goods; 10-foundry goods local thermal center;
Be described in detail with reference to accompanying drawing below with reference to embodiment of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, a kind of mould with insulated feeder, comprise left mould 1, right mould 3, left mould 1 is provided with die cavity 5 with right mould 3 joint inside, is provided with contracting neck 7, is provided with open riser 4 above contracting neck 7 above die cavity 5, the internal side wall of open riser 4 is provided with asbestos board 2, be provided with blind riser 6 in the middle part of die cavity 5, blind riser 6 internal side wall is provided with asbestos board 2, and the side of blind riser 6 is provided with venting plug 8.
Described contracting neck 7 is of a size of 5mm ~ 10mm.
The material of described left mould 1 and described right mould 3 is the one in mould steel, gray iron.
Described asbestos board 2 surface scribbles thermal insulation coatings.
After injecting aluminium liquid in die cavity 5, form product foundry goods, product foundry goods is in forming process, and the thick general goal thermal center 9 of foundry goods appears in cast top, occurs foundry goods local thermal center 10 in the middle part of foundry goods.
The thick general goal thermal center 9 of foundry goods with open riser 4 finish dimensional ratio is: 1:0.8 ~ 1:1.
Foundry goods local thermal center 10 with blind riser 6 finish dimensional ratio is: 1:1.2 ~ 1:1.4.
Operation principle of the present utility model is as follows:
Left mould 1 and right mould 3 open riser 4, blind riser 6 surface steel are carved hacking (contracting neck 7 is not beaten); surface sand-blasting is cleaned out; be heated to 150 ± 30 DEG C; asbestos board 2 water-soaked; skim waterglass is smeared in side; (contracting neck 7 does not glue) inside open riser 4 and blind riser 6 is sticked to type; then beat solid with iron staff with type always; until parch; clean out the unnecessary asbestos board in rising head edge; one deck asbestos board 2 can be glued again in blind riser 6 bottom, commonly use thermal insulation coatings protection at asbestos board 2 external coating one deck more afterwards.By above-mentioned steps after open riser 4 and blind riser 6 glue asbestos board 2, close tight left mould 1 and right mould 3, mold heated, to requiring temperature, injects aluminium liquid at die cavity 5, after the time to be solidified arrives, open left mould 1 and right mould 3, take out product foundry goods, at this moment, open riser 4, blind riser 6 first half outward appearance have turn white normally shrinkage porosite or shrinkage cavity, illustrate that riser head heat-preserving feeding effect is very good, completely the defect at thick for foundry goods general goal thermal center 9 or thermal center 10 place, foundry goods local is transferred in rising head.
Wherein asbestos board 2 is special asbestos board, scaling loss amount≤20%; High temperature resistant more than 800 DEG C; Medium density; 5 ~ 7 grades of asbestos mixed pressures make.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the various improvement that method of the present utility model is conceived and technical scheme is carried out; or directly apply to other occasion, all within protection domain of the present utility model without improving.
