Abstract
The invention relates to a one-mold multi-cavity structure of a polyurethane (PU) foaming mold. The structure comprises a mold, wherein the mold is provided with a plurality of independent cavities and a filling port. The innovation point is that: the filling port is communicated with the cavities through a main runner and branch runners; a flow regulation mechanism is arranged on the communicated part of each branch runner and each cavity and comprises a double ejector rod cylinder; a sliding block which can be inserted into each branch runner is arranged at the lower end of a piston rod of each cylinder; and a limit nut is arranged at the upper end of each piston rod. After the mold is arranged on foaming equipment, trial production is performed, and the limit nut at the upper end of each piston rod is regulated according to the actual product condition of each cavity, so that the cross section of each branch runner is changed, the doses of foaming materials which enter the cavities are the same, and the one-mold multi-cavity structure is truly realized.
Description
Technical field
The present invention relates to a kind of foaming mould, particularly a kind of PU foaming mould a multi-cavity mold structure.
Background technology
Traditional P U (polyurethane) foaming mould is a mould one cavity configuration basically, and promptly a mould can only process a product by single, and working (machining) efficiency is very low.The PU foaming mould that a multi-cavity mold structure is also arranged on the market, the problem that its structure exists is: the dosage of PU foamed material is less, need not to fill with whole die cavity; And because the installation levelness of mould, or each branch flow passage roughness of mould, cross section and length etc. can't be in full accord; Therefore when reinforced, the foamed material that gets into each die cavity can't be accomplished in full accord, directly has influence on the quality of foamed products, can't really realize a multi-cavity mold structure.
Summary of the invention
The technical problem that the present invention will solve provides the high PU foaming mould of a kind of foamed products quality a multi-cavity mold structure.
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of PU foaming mould a multi-cavity mold structure, comprise mould, and said mould has several independent die cavities; Establish sprue on the said mould; Its innovative point is: said sprue is communicated with each die cavity through total runner and branch flow passage, and said branch flow passage is provided with flow control device with the place of connection of each die cavity, and said flow control device comprises a pair of rod cylinder; The piston-rod lower end of said cylinder is established the slide block that can insert branch flow passage, and said piston rod upper end is provided with stop nut.
The invention has the advantages that: after being installed to mould on the foaming machine; Manufacture experimently; The product situation actual according to each die cavity regulated the stop nut of cylinder piston rod upper end, thereby changes the cross section of each branch flow passage; Make that the foamed material dosage that gets into each die cavity is identical, thereby really realize a multi-cavity mold.
Description of drawings
Fig. 1 is PU foaming mould a multi-cavity mold vertical view of the present invention.
Fig. 2 is along A-A line cutaway view among Fig. 1.
The specific embodiment
Like Fig. 1, shown in 2, comprise mould 1, die cavity 2, sprue 3, total runner 4, branch flow passage 5, cylinder 6, slide block 7, stop nut 8.
Above-mentioned mould 1 has several independent die cavities 2; Establish sprue 3 on the mould 1; Sprue 3 is communicated with each die cavity 2 with branch flow passage 5 through total runner 4, and branch flow passage 5 is provided with flow control device with the place of connection of each die cavity 2, and this flow control device comprises a pair of rod cylinder 6; The piston-rod lower end of cylinder is established the slide block 7 that can insert branch flow passage 5, and the piston rod upper end is provided with stop nut 8.
During use, after being installed to mould 1 on the foaming machine, elder generation manufactures experimently the product situation actual according to each die cavity; Regulate the stop nut 8 of cylinder piston rod upper end; Thereby change the cross section of each branch flow passage 5, make that the foamed material dosage that gets into each die cavity is identical, thereby really realize a multi-cavity mold.
