APG moulding process automation material feeding structure
Technical field:
The present invention relates to a kind of APG technology, relate in particular to material feeding structure in this APG technology.
Technical background:
APG technology is meant automatic pressure gel (Automatic Pressure Generator), a kind of technology of promptly using epoxide resin material to be shaped by the thermosetting mold injects.
APG produces at every turn and adopts manual mode pressurization, pressure release to carry out material feeding in the prior art.As shown in Figure 1: among the figure: batch can 1; Visor 2 on the batch can; Connect the plug valve 12 under the batch can; The make-up machine 9 that links to each other with plug valve 12; Make-up machine 9 links to each other with PLC workstation1 0; Motor 3 on batch can; Air inlet ball valve 61 links to each other respectively with main body batch can 1 with venting ball valve 62; On batch can, also connect a safety valve 7; Venting ball valve 62 links to each other with pressure valve 4; Air inlet ball valve 61 links to each other with air compressor 8 by air accumulator 71.
Said structure is manually to control main body batch can 1 to carry out material feeding production by air inlet ball valve 61 and venting ball valve 62; But owing to produce the unstability of pressure, As time goes on corresponding the variation takes place in material behavior, and then product quality stability is played certain restriction.
Summary of the invention:
The technical issues that need to address of the present invention have provided a kind of APG moulding process automation material feeding structure, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes: batch can; Visor on the batch can; Connect the plug valve under the batch can; The make-up machine that links to each other with plug valve; Make-up machine links to each other with the PLC work station; Motor on batch can; The air inlet ball valve links to each other respectively with the main body batch can with the venting ball valve; On batch can, also connect a safety valve; The venting ball valve links to each other with pressure valve; The air inlet ball valve links to each other with air compressor by air accumulator; Also comprise: the constant pressure valve between air inlet ball valve and batch can; Dynamic valve between plug valve and make-up machine; Described dynamic valve also links to each other with the PLC work station.
Compared with prior art, the invention has the beneficial effects as follows: guarantee stable processing technique, make batch can keep certain technological parameter requirement, keep injection pressure to stablize constant; Energy-saving and cost-reducing, add certain pressure to batch can after, need not pressure release.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
As seen from Figure 2: the present invention includes: batch can 1; Visor 2 on the batch can; Connect the plug valve 12 under the batch can; The make-up machine 9 that links to each other with plug valve 12; Make-up machine 9 links to each other with PLC workstation1 0; Motor 3 on batch can; Air inlet ball valve 61 links to each other respectively with main body batch can 1 with venting ball valve 62; On batch can, also connect a safety valve 7; Venting ball valve 62 links to each other with pressure valve 4; Air inlet ball valve 61 links to each other with air compressor 8 by air accumulator 71; Also comprise: the constant pressure valve 5 between air inlet ball valve 61 and batch can 1; Dynamic valve 11 between plug valve 12 and make-up machine 9; Described dynamic valve 11 also links to each other with PLC workstation1 0.
The present invention adds a control program by installing dynamic valve additional in the PLC work station, make the folding and the dynamic valve synchronous working of mould.
The present invention is compared with prior art:
