Abstract
The utility model relates to an integral mould for forming foaming machine for lost-foam casting, which comprises an upper half module and a lower half module. The utility model is characterized in that the upper half mold and the lower half mold are uniformly composed of a model of concave-convex structure and a hollow heating air chamber which are cast integrally. An airflow channel is communicated from the air chamber to the concave part of the model. The utility model has the advantages that because an integral cast structure is adopted by the utility model, the material uniformity and the wall thickness evenness of the model and the air chamber are assured, the quality of a foam module and qualified rate of production are improved, and meanwhile the service life of die is also extended.
Description
Technical field
The utility model belongs to casting technique equipment technology field, relates in particular to a kind of disappearance mold forming foaming machine unitary mould.
Background technology
Our the disappearance mould mould structure characteristics once used are aborning: on, the counterdie mould is assemblied by two parts, a part is a model, a part is an air chamber, model part and mould air chamber part are connected and fixed with bolt, air chamber is welded with angle steel, putting heat-resisting rubber in the middle of air chamber and model two parts leaks gas when preventing logical steam, this mould structure finds after a period of time that through using the subject matter that produces is: easily gas leakage in the middle of the two parts at mould when leading to steam under certain pressure, the local steaming of foam mould is not yet done, and moulding is incomplete, profile is unintelligible.Foam mould percent defective is up to more than 5%, mould is through using because different with air chamber material and wall thickness after being heated after a while, cause the cooling velocity difference, the mold former part is yielding, so the foam of producing is yielding, and the generation overlap, foam mould percent defective reaches more than 4%, reduces die life.Use very short heat-resisting rubber of a period of time just to need to change because of being subjected to corrosion and damage in addition, production cost significantly increases, and influences production efficiency.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and long service life can solve the quality problems of foam mould effectively, enhances productivity the disappearance mold forming foaming machine unitary mould that reduces production costs.
According to disappearance mold forming foaming machine unitary mould described in the utility model, comprise, following two half modules, it is characterized in that described upper and lower two half modules form by the model of casting all-in-one-piece concaveconvex structure and the heating air chamber of hollow, be communicated with gas channel by air chamber to the recess of model.
The male and female face of convex-concave structure model described in the utility model can be square or circular male and female face.
Integral casting forming model described in the utility model and hollow gas chamber can be made with aluminum alloy materials.
Because the utility model adopts the integrally casting structure, solved the perishable problem of leaking gas of causing of the heat-resisting rubber of split mould in the past effectively, the material one of having guaranteed model and the air chamber wall thickness of making peace is even, improve the quality and the product percent of pass of foam mould, also prolonged the service life of mould simultaneously.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model disappearance mold forming foaming machine with unitary mould.
Accompanying drawing 2 is the user mode figure of the utility model disappearance mold forming foaming machine with unitary mould.
The specific embodiment
With reference to the accompanying drawings, the utility model will be further described by embodiment.
Referring to attached Fig. 1 and 2, the utility model disappearance mold forming foaming machine unitary mould, comprise upper and lower two half modules, it is characterized in that described upper and lower two half modules form by the model 1 of casting all-in-one-piece concaveconvex structure and the heating air chamber 2 of hollow, be communicated with gas channel 3 by air chamber 2 to the recess of model 1.This mould is installed on the last lower platform 5 of moulding foaming machine with fixing foundary weight plate 4, makes hollow gas chamber 2 formation one confined space, stopped gas leak phenomenon effectively.Integrated model 1 of the utility model and hollow gas chamber 2 preferably adopt aluminum alloy materials to make, and can improve thermal conductivity and corrosion resistance effectively like this.Because the model and the air chamber of this mould are overall structure, not only to make simply, cost is low, and product percent of pass institute is high more than 10%, and die life is long.
The male and female face of convex-concave structure model 1 described in the utility model can be made square or circular male and female face according to the needs of making foam mould shape.
Claims (3)
1, a kind of disappearance mold forming foaming machine unitary mould, comprise upper and lower two half modules, it is characterized in that described upper and lower two half modules form by the model of casting all-in-one-piece concaveconvex structure and the heating air chamber of hollow, be communicated with gas channel by air chamber to the recess of model.
2, disappearance mold forming foaming machine unitary mould according to claim 1, the male and female face of described convex-concave structure model can be square or circular male and female face.
3, disappearance mold forming foaming machine unitary mould according to claim 1, described integral casting forming model and hollow gas chamber can adopt aluminum alloy materials to make.
