Description
Technical field
The present invention relates to a kind of foaming mould, particularly a kind of PU Car Cushion manufacturing foaming mould.
Background technology
Automobile manufacturing enterprise is when producing the PU Car Cushion, the top of PU Car Cushion is U-shaped, this kind structure is when carrying out Design of Dies, 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 during the demoulding, product can be followed patrix together, 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 affect quality; In addition, after product is opened with patrix, from fore side away from, give and to get product and bring inconvenience.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of PU Car Cushion manufacturing foaming mould that efficient is high, be convenient in demoulding of making.
for solving the problems of the technologies described above, technical scheme of the present invention is: a kind of PU Car Cushion manufacturing foaming mould, comprise top mold frame, lower mold holder and mould, the end of top mold frame and lower mold holder is hinged by hinge, the both sides of lower mold holder are equipped with mould bases upset cylinder, 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 patrix, counterdie and intermediate mass, the end of upper die and lower die is hinged, counterdie is fixed on lower mold holder, intermediate mass is arranged between upper die and lower die, be equipped with on 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 top mold frame.
Further, described separation driving mechanism comprises patrix skeleton, leading arm, guide limiting stopper, adpting flange, directive wheel and guide 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 arranges respectively guide limiting stopper, be 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 guide cylinder that drives leading arm.
Further, also be provided with automatic locking mechanism on described separation driving mechanism, automatic locking mechanism comprises locking cylinder, lock shaft, detector, and locking cylinder is arranged on the patrix skeleton by the locking cylinder holder, and the piston rod end of locking cylinder connects lock shaft; The leading arm sidewall tieholen of unblanking, detector are arranged on the patrix skeleton of locking cylinder below, control locking cylinder by control system according to detector signal and stretch into locking hole or retraction.
The invention has the advantages that: upper and lower mould is connected through the hinge, and product moves with patrix, intermediate mass, is forever one with respect to counterdie and rotatablely moves, and this moment, the possibility of lower bad product of die drawing reduced greatly; 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 when mould is opened product, ejects product together 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 coordinate 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 by detector, leading arm drives lock shaft lock core leading arm by locking cylinder when top dead centre, avoid the guide cylinder rear unexpected tenesmus of breaking down to injure operating personnel by a crashing object, improve security reliability.
