Abstract
The utility model relates to a core pulling mechanism for a PU (Polyurethane) foaming mould with a frame. The core pulling mechanism comprises an upper mould, and is characterized in that a plurality of inserts for fixing the frame are arranged in an upper mould cavity; clamping pins with end parts capable of protruding from the upper surface of the upper mould are fixed at the top ends of the inserts; annular clamping grooves are formed at the end parts of the clamping pins; a clamping air cylinder is mounted on the upper surface of the upper mould; the end part of a piston rod of the clamping air cylinder is connected with a limiting block capable of stretching into or leaving the annular clamping grooves; a push-out air cylinder is mounted on the upper surface of the upper mould; and a piston rod of the push-out air cylinder is over against the end faces of the clamping pins protruding from the upper surface of the upper mould. As the inserts are attracted by magnets and the frame is located and fixed by the inserts, the limiting block is driven by the clamping air cylinder to be embedded into the annular clamping grooves of the inserts to avoid falling-off of the inserts; after foaming is finished, the limiting block is driven by the clamping air cylinder to leave the annular clamping grooves and be pushed out by the push-out air cylinder; the inserts is detached from an upper mould surface; and the inserts are demoulded with a product. The frame is accurate to locate, and the quality of the foaming product is ensured.
Description
Technical field
The utility model relates to a kind of foaming mould, particularly a kind of band skeleton PU foaming mould core-pulling mechanism.
Background technology
During with the PU foamed products of skeleton, the steel-wire carcass of patrix can't or be difficult to be fixed to the corresponding position of patrix at all, even put up reluctantly, product can't be taken off after foaming finishes so at all in manufacturing.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of framework location accurately, the band skeleton PU foaming mould core-pulling mechanism of convenient disassembly.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of band skeleton PU foaming mould core-pulling mechanism, comprise patrix, its innovative point is: be provided with inserting of some fixedly skeletons in the described upper model cavity, described top of inserting is fixed with the clamping pin of the extended patrix upper surface in end, and the end of clamping pin has the ring gripping groove; Described patrix upper surface is equipped with gripper cylinder, and the piston rod end of described gripper cylinder is connected with the limited block that can stretch into or leave the ring gripping groove; Described patrix upper surface also is equipped with the release cylinder, and the piston rod of described release cylinder is over against the clamping pin end face that stretches out the patrix upper surface.
Further, describedly be inlaid with and the corresponding magnet of inserting in the patrix profile.
The utility model has the advantage of: hold by magnet and insert, by inserting framework location is fixed, gripper cylinder drives limited block and embeds the ring gripping groove of inserting, and avoiding inserting comes off; After foaming was finished, gripper cylinder drove limited block away from the ring gripping groove, and again by releasing cylinder ejector, will insert breaks away from the patrix profile, inserts with the product demoulding.Framework location is accurate, convenient disassembly, can utilize in addition insert with face that patrix cooperates on open little air discharge duct, be convenient to product and foam fully herein, avoid that the zone is too little can't install exhaust cylinder at all herein, cause feeling suffocated and cause the product foaming not exclusively, guarantee the foamed products quality.
Description of drawings
Fig. 1 is the utility model band skeleton PU foaming mould core-pulling mechanism structural representation.
Fig. 2 is partial enlarged drawing A among Fig. 1.
The specific embodiment
As shown in Figure 1, 2, comprise patrix 1, insert 2, clamping pin 3, gripper cylinder 4, limited block 5, release cylinder 6.
Be provided with in the die cavity of above-mentioned patrix 1 some for fixing skeleton insert 2, be fixed with clamping pin 3 on 2 the top of inserting, the end of clamping pin 3 has the ring gripping groove; Be drilled with through hole on the profile of patrix 1, insert when being close to the profile of patrix 1, the end ring gripping groove of clamping pin 3 stretches out patrix 1 upper surface.
Patrix 1 upper surface is equipped with gripper cylinder 4, and the piston rod end of gripper cylinder 4 is connected with the limited block 5 that can stretch into or leave the ring gripping groove; The patrix upper surface also is equipped with releases cylinder 6, releases the piston rod of cylinder 6 over against clamping pin 3 end faces that stretch out patrix 1 upper surface.
In addition, be inlaid with and the 2 corresponding magnet 7 of inserting in patrix 1 profile.
Operation principle: hold by magnet 7 and to insert 2,2 pairs of skeletons, 8 location are fixing by inserting, and gripper cylinder 4 drives limited blocks 5 and embeds 2 the ring gripping groove of inserting, and avoid inserting 2 coming off; After foaming was finished, gripper cylinder 4 drove limited block 5 away from the ring gripping groove, and again by releasing cylinder ejector, the 2 disengaging patrix profiles of will inserting insert 2 with the product demoulding.
