Abstract
The invention discloses a method for manufacturing a model with a mark on a lost foam pipe fitting, and belongs to the field of manufacturing of molds in casting of nodular cast iron pipe fittings. The method comprises the following two steps: A) making a foam model of the mark; B) and D) sticking the marked foam model obtained in the step A) and the pipe foam model into a whole to obtain the foam model with the mark on the pipe. The invention has the advantages of saving P-S foam beads, saving the number of moulds and reducing the production cost. And meanwhile, the foam model of the lost foam pipe fitting is more flexible to produce.
Description
Technical field
The invention discloses the preparation method that the model of sign is arranged on a kind of lost-foam pipe spare, belong to the Mold Making field in the casting nodular cast iron pipe fittings.
Background technology
Because lost-foam pipe spare product structure is complicated, specifications and models and kind are more, and the user is difficult to distinguish, and need mark product on one's body at pipe fitting for the ease of the identification of product and identify.The mark mode of the product of industry pipe fitting sign mainly adopts the mode of casting at present, directly will identify casting on the pipe shaft of pipe fitting.The mark mode of this pipe fitting sign mainly is will identify on the mould in the stamp, and on bubbles model, form sign through foaming.Its shortcoming of mark mode of this pipe fitting sign is: because pipe fitting has a hundreds of kind, as will all pipe fittings being assorted, need join the hundreds of mold.With taking a large amount of funds, increased the cost of manufacturer accordingly.Therefore be badly in need of wanting a kind of and can the product sign be cast on the pipe fitting technology that does not take a large amount of moulds and practice thrift cost again.
Summary of the invention
The invention provides a kind of saving P-S foam beads, practice thrift number of molds, and the pipe fitting model of the advantage that effectively reduces production costs.Also make the production of bubbles model of lost-foam pipe spare more flexible simultaneously.
For realizing above-mentioned technical purpose, technical scheme of the present invention is following:
The preparation method that the model of sign is arranged on a kind of lost-foam pipe spare, adopt following steps:
A), make the bubbles model of sign;
B), with A) the sign bubbles model that obtains of step and pipe fitting bubbles model are pasted is an integral body, obtain having on the pipe fitting bubbles model of sign.
A described in the present invention) step is specific as follows:
A), making thickness is the mold cavity of 20mm aluminium sheet;
B), said mold cavity inwall carved with mark;
C), in said mold cavity, charge into P-S foam beads and closed mold cavity,
D), with c) to put into temperature be 60 ℃---steam cylinder heating of 80 ℃ 40 seconds---70 seconds for the mold cavity that obtains;
E), with d) mold cavity that obtains of step takes out, and opens mold cavity, obtains identifying model.
B according to the invention) the last 851 stick is adopted in the stickup in the step.
The P-S bead is a kind of of Dragon King's board expandable polystyrene, bead diameter between 0.2mm-0.4mm by seeing that imperial chemical industry limited company produces.The last 851 stick is to be produced by the flourishing adhensive factory of Zichuan Huang Jiapu.
Adopt the beneficial effect and the principle of technique scheme to be:
At first, because with pipe fitting model and sign model foaming respectively, as long as model is the same, same sign can stick on the pipe fitting of different size, has increased compound mode, therefore, make that the production of bubbles model of lost-foam pipe spare is more flexible;
Secondly, because with pipe fitting model and sign model difference foaming, the manufacturer only needs disposable sign die sinking with different model to get final product; Produce the sign model then, as required sign is sticked on the pipe fitting model, therefore; This mode need be with the pipe fitting of different size, different model die sinking tool all, so; Practice thrift a large amount of die sinking expenses, directly reduced production cost; Reduced factory's bubbles model of 60% nearly;
The 3rd, adopt this mode, can also be used to the not sign pipe fitting model that has processed, only need identify modelling good after, stickup gets final product, and like this, can not cause waste;
Four, because the wall thickness of sign mold cavity is 20mm, reduced die cost,, adopted the mold cavity of 20mm wall thickness, will not reach the moulding requirement if sign is one-body molded with the pipe fitting employing, and then bigger loss;
Five, adopt the moulding of P-S foam beads, reduced material cost, also make model forming stable;
Six, the temperature with steam cylinder is controlled at 60 ℃---and 80 ℃; Effectively utilized the condition of P-S foam beads expansion molding; The temperature that the P-S foam beads expands is at 60 ℃---between 80 ℃; Temperature is higher than can make foam vaporization more than 85 ℃. can be so that foam expansion, and can not make the foam vaporization again and disappear, further make the bubbles model stable molding;
Seven, mold cavity was controlled at 40 seconds in the interior heat time heating time of steam cylinder---70 seconds, further ensured the bubbles model stable molding;
Eight, adopt bonding sign model of the last 851 stick and pipe fitting model, after the The model vaporization disappears, utilize the characteristic of the last 851 stick, can not stay residue or impurity,, take a firm foundation for the last moulding of pipe fitting.
