Abstract
The utility model discloses an easily-de-molded polyurethane foaming mould comprising an upper mould and a lower mould, wherein after the upper mould and the lower mould are closed, the interior is provided with a mold cavity; and the lower mould is provided with an air blowing hole which is communicated with the bottom of the mold cavity. The easily-de-molded polyurethane foaming mould has the characteristic of easiness for de-molding, guarantees that molded composite sponge is not damaged in a de-molding process, and simultaneously has the advantages of reducing the appearance deformation of the composite sponge and improving the quality of the composite sponge.
Description
Technical field
The utility model belongs to technical field of mold, relates to a kind of polyurethane foam mould.
Background technology
Generally auxiliary stripper apparatus all was artificial free-hand delivery when polyurethane foam closed continuous die sinking pickup.Because the particularization of some special type die structure, the time when demoulding is arranged the product part tear situation, influence the product appearance quality, reduce operating efficiency, increase bad result such as extra artificial repairing cost.
The utility model content
The utility model technical problem to be solved provides a kind ofly can not close the polyurethane foam mould of the continuous hurtful easy demoulding to moulding when the demoulding, to overcome the deficiency that prior art exists.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of polyurethane foam mould of the easy demoulding comprises upper die and lower die, inner tool die cavity after the said upper die and lower die closure, and it is characterized in that: said counterdie has the gas hole that is communicated to cavity bottom.
The air auxiliary valve is installed on the said gas hole.
In the specific embodiment of the utility model; Said air auxiliary valve by cylinder, be located at the piston in the cylinder and the plug that is connected on the piston constitutes; Said cylinder is positioned at piston one side and has first air inlet; Be positioned at the piston opposite side and have second air inlet, the position of the corresponding plug of said cylinder has the gas outlet.
Adopt technique scheme, during the mould die sinking, under the instruction of travel switch, the air auxiliary valve is opened, and air blows to moulding in the die cavity and closes silk floss and it is boosted in channel set, eliminated the problem of tearing during again by the staff pickup.Simultaneously, have higher hot gas generation owing to close continuous in the mold cavity of closure, the foaming, closing silk floss often has the air heave phenomenon; And the cold air that air valve blows out can be with the local cooling of product; Make and close continuous deliquescing, be convenient to the demoulding, involutory silk floss plays cytoclastic effect simultaneously, reduces and closes continuous outward appearance distortion.
Therefore, the utlity model has the characteristics that are prone to the demoulding, moulding is closed continuous injury-freely when having guaranteed the demoulding, and has simultaneously to reduce and closes continuous outward appearance distortion, improves the advantage that continuous quality is closed in moulding.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is an air auxiliary valve closed condition sketch map;
Fig. 3 is an air auxiliary valve opening sketch map;
Among the figure:
The 100-patrix, the 200-counterdie, the 300-die cavity, 400-closes silk floss, 500-gas hole, 600-air auxiliary valve, 601-cylinder, 602-piston, 603-plug, 604-first air inlet, 605-second air inlet, 606-gas outlet.
The specific embodiment
As shown in Figure 1, the polyurethane foam mould of the easy demoulding of the utility model comprises patrix 100 and counterdie 200, and patrix 100 and the inner tool die cavity 300 in counterdie 200 closed backs should carry out polyurethane foam in this die cavity 300, close continuous 400 with formation.
The improvements of the utility model type are on counterdie 200, to offer the gas hole 500 that is communicated to die cavity 300 bottoms, and air auxiliary valve 600 is installed on gas hole 500.
In conjunction with shown in Figure 2; Air auxiliary valve 600 by cylinder 601, be located at the piston 602 in the cylinder 601 and the plug 603 that is connected on the piston 602 constitutes; Cylinder 601 is positioned at piston 602 1 sides and has first air inlet 604; Be positioned at piston 602 opposite sides and have second air inlet 605, the position of corresponding plug 603 has gas outlet 606 on the cylinder 601, and this gas outlet 606 is connected on the gas hole 500 of counterdie 200.
More than be exactly the polyurethane foam mould of the easy demoulding of the utility model, its working method is following:
As shown in Figure 2, during mold closing, let air get into cylinder 601 from first air inlet 604, air push piston 602 drives plug 603 gas outlet 606 is blocked.At this moment mould gets into and closes continuous foaming stages.
As shown in Figure 3, during die sinking, let air get into cylinder 601 from second air inlet 605; Air push piston 602 drives plug 603 to be separated with gas outlet 606; Let air-flow get into the die cavities 300 from gas hole 500, thus with moulding close that silk floss boosts and simultaneously involutory silk floss cool off, as shown in Figure 1.
The utility model closes continuous problem of tearing easily when having solved the demoulding.Have higher hot gas generation owing to close continuous in the mold cavity of closure, the foaming simultaneously; Closing silk floss often has the air heave phenomenon, and the cold air that air valve blows out can make the local cooling of product close continuous deliquescing, be convenient to the demoulding; Involutory silk floss plays cytoclastic effect simultaneously, reduces and closes continuous outward appearance distortion.
Through measuring and calculating; It is 120pcs that continuous quantity is closed in average every secondary mould daily output; Each closes silk floss has 1 place to tear spent manual work to repair and can improve through blowning installation; Can practice thrift so and repair glue consume expense and be: 120pcs * 0.3 yuan/PCS (every is closed continuous glue expense)=36 yuan, manual work expends: it is 36+3.3=39.3 unit that 120pcs * 10s/pc (every place repairs consuming time) * 10 yuan/H=3.3 unit, then single mould practice thrift total cost every day.The existing 20 secondary moulds of company have the die sinking tearing defect; And scrap 4pcs average every day; Close 250 yuan/pc of continuous cost; Then year benefit=(39.3 yuan/day+4pcs/ days * 250 yuan/pc) * 26 day/month (every month producing days) * December-600 (air valve unit price) * 20 (the mould number is torn in the existing die sinking of company)=312261.6 yuan, benefit is considerable!
But; Those skilled in the art will recognize that; The above-mentioned specific embodiment is exemplary, is to be the restriction to this patent protection domain in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope of this patent protection.
