The foaming mold for manufacturing the PU (polyurethane) automobile back cushion is characterized in that the mold comprises an upper mold, a lower mold and an intermediate mold; tail ends of the upper mold and the lower mold are articulated; the lower mold is fixed on the lower mold frame; the intermediate block is arranged between the upper mold and the lower mold; a separating driving mechanism for driving the intermediate block is installed on the upper mold; and a mold opening chain is arranged between the back surface of the upper mold and the upper mold frame. The upper mold and the lower mold are connected through an articulated chain, the product acts along with the upper mold and the intermediate block together, the product moves rotatably permanently relative to the lower mold, and at the same time, the possibility for pulling the product to be damaged by the lower mold is reduced greatly; and additionally, when the mold is opened and the product is removed, the product and the intermediate block are projected out together, and the foamed product is more convenient to be taken down by the operation personnel.
Description
Technical field
The present invention relates to a kind of foaming mould, foaming mould is used in the manufacturing of particularly a kind of PU Car Cushion.
Background technology
Automobile manufacturing enterprise is when producing the PU Car Cushion, and the top of PU Car Cushion is a U-shaped, and this kind structure is when carrying out the mould design; There is certain shortcoming: because the product top is into the U-shaped shape; First element during die sinking is moving both vertically of mould bases, and product can be followed patrix together during the demoulding, and product equally also moves both vertically with respect to counterdie; This moment, counterdie had the place of overhead kick can hold product, and demoulding difficulty is easy to draw product bad; While is very poor at the top exhaust effect of the product of patrix, and exhaust cylinder can't be installed, and finally causes the product foaming not exclusively to influence quality; In addition, far away after product is opened with patrix from fore side, bring inconvenience to getting product.
Summary of the invention
The technical problem that the present invention will solve provides a kind of PU Car Cushion manufacturing of making the efficient height, being convenient in demoulding and uses foaming mould.
For solving the problems of the technologies described above, technical scheme of the present invention is: foaming mould is used in the manufacturing of a kind of PU Car Cushion, comprises top mold frame, following mould bases and mould; The end of top mold frame and following mould bases is hinged through hinge, and the both sides of following mould bases are equipped with mould bases upset cylinder, and the piston rod of mould bases upset cylinder and two middle side parts of top mold frame are hinged; Its innovative point is: mould comprises upper die and lower die and intermediate mass; Upper die and lower die terminal hinged, counterdie is fixed on down on the mould bases, and intermediate mass is arranged between the upper die and lower die; Be equipped with on the patrix drive intermediate mass near or away from the separation driving mechanism of patrix, be provided with the die sinking chain between the back side of patrix and the top mold frame.
Further; Said separation driving mechanism comprises patrix skeleton, leading arm, guide and limit piece, adpting flange, directive wheel and guiding cylinder; The patrix skeleton is built-in with the leading arm that stretch out at a pair of two ends; The adpting flange that the front end setting of two leading arms is connected with intermediate mass; The leading arm end is provided with the guide and limit piece respectively, is equipped with in the patrix skeleton of each leading arm both sides that array clamps leading arm and to its directive wheel that leads, the upper end of patrix skeleton is equipped with the guiding cylinder that drives leading arm.
Further; Also be provided with automatic locking mechanism on the said separation driving mechanism; Automatic locking mechanism comprises locking cylinder, lock shaft, detector, and locking cylinder is installed on the patrix skeleton through the locking cylinder holder, and the piston rod end of locking cylinder connects lock shaft; The leading arm sidewall tieholen of unblanking, detector are installed on the patrix skeleton of locking cylinder below, stretch into locking hole or withdrawal by the control system according to detector signal control locking cylinder.
The invention has the advantages that: upper and lower mould is connected through the hinge, and product moves with patrix, intermediate mass, is one forever with respect to counterdie and rotatablely moves, and this moment, the possibility of bad product of die drawing reduced greatly down; The intermediate mass that increases simultaneously and the die joint of patrix also can play the effect of exhaust, are convenient to simultaneously come exhaust at the top of product installation exhaust cylinder; The separation driving mechanism of design ejects product when moulds open is removed product with intermediate mass in addition, is more convenient for the product that it is good that operating personnel will foam to take off.
Separate driving mechanism and adopt leading arm and directive wheel to cooperate realization, leading arm can be arranged to arc, guarantees to rest on after intermediate mass is opened suitable angle and is convenient to take off the PU foamed products.
The self-closing retaining mechanism that separates driving mechanism can detect the leading arm position through detector; Leading arm drives lock shaft lock core leading arm through locking cylinder when top dead centre; Tenesmus suddenly injured operating personnel by a crashing object after the cylinder of avoiding leading broke down, and improved security reliability.
