Technical field
The invention belongs to the moulds of industrial equipment designing technique, relate to a kind of method of utilizing silicone rubber tube to the sealing of mould die joint.
Background technology
The branch half hitch that vacuumizes moulding for employing constitutes pattern, divides half position generally to adopt whole subcontracting mode or beat the vacuum bag mode by the part at it and seals.
This conventional encapsulating method is seen fairly simple from a use angle, but can directly destroy hermetically-sealed construction because of decomposing the die body loose piece during each product molding, all will carry out once again after each matched moulds operation, encapsulant can only be used once, cost is higher, and complex operation.In a single day in the extrusion forming solidification process of heating, seal to go wrong in addition and cause product rejection because of handling.
Summary of the invention
The objective of the invention is to propose a kind of reusable a kind of method of utilizing silicone rubber tube to the sealing of mould die joint easy and simple to handle, with low cost.Technical solution of the present invention is,
(1) on the die joint of last shaping mould or compacted under mould, makes " Ω " type groove of placing silicone rubber tube;
(2) silicone rubber tube is placed in " Ω " type groove, the two ends of silicone rubber tube are two adapter couplings of socket respectively, and the ring flange of adapter coupling rear end is fixed on shaping mould and the compacted under mould; After silicone rubber tube passed from the centre bore of adapter coupling, counter turning on the cylindrical that is wrapped in adapter coupling was squeezed on the adapter coupling with the termination of gland with silicone rubber tube, and wherein the gland of an end is connected with loading line by one-way cock;
(3) opening source of the gas fits the last shaping mould of mould and the die joint of compacted under mould to the silicone rubber tube inflation.
The rear end of described adapter coupling is that ring flange and last shaping mould and compacted under mould are fixed, and the front end of adapter coupling is that taper is threaded with gland.
When the external diameter of silicone rubber tube is 8mm, during wall thickness 1mm, the blowing pressure is 0.5MPa.
Advantage that the present invention has and beneficial effect, the present invention is directed to and adopt the more complicated of vacuum pumping method moulding to divide the half module tool that a kind of silicone rubber tube aeration Sealing Technology is provided, by in silicone rubber tube, filling the sealing of barotropic gas realization to the mould die joint, thereby guarantee the air-tightness of entire die in the process that vacuumizes the extrusion forming product of heating, divide half module tool conventional seals method complex operation to improve, the problem of control difficulty, simplify seal operation, make the pressurization process controlled, improve the quality of products, reduce scrappage, avoided the drawback of conventional seals method when large mold is sealed.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A view of Fig. 1.
The specific embodiment
Below the present invention is described in further details.Referring to Fig. 1, silicone rubber tube aeration Sealing Technology needs a sealing system, is made up of silicone rubber tube 1, adapter coupling 2, gland 3, one-way cock 4, loading line 5.The sealing system is used to adopt the more complicated of vacuum pumping method moulding to divide the half module tool, and its encapsulating method is,
(1) on the die joint of last moulding 6 moulds or compacted under mould 7, makes " Ω " type groove of placing silicone rubber tube;
(2) silicone rubber tube 1 is placed in " Ω " type groove, the two ends of silicone rubber tube 1 are two adapter couplings 2 of socket respectively, and the ring flange of adapter coupling 2 rear ends is fixed on shaping mould 6 and the compacted under mould 7; After silicone rubber tube 1 passed from the centre bore of adapter coupling 2, counter turning on the cylindrical that is wrapped in adapter coupling 2 was squeezed on the adapter coupling 2 with the termination of gland 3 with silicone rubber tube 1, and wherein the gland 3 of an end is connected with loading line 5 by one-way cock 4;
(3) opening source of the gas fits the last shaping mould 6 of mould and the die joint of compacted under mould 7 to silicone rubber tube 1 inflation.
The rear end of described adapter coupling 2 is that ring flange and last shaping mould 6 and compacted under mould 7 are fixing, and the front end of adapter coupling is that taper is threaded with gland.
When the external diameter of silicone rubber tube 1 is 8mm, during wall thickness 1mm, the blowing pressure is 0.5MPa.
Silicone rubber tube 1 is installed in the groove of composite material mould, by in silicone rubber tube, filling the sealing of barotropic gas realization the mould die joint.The length of silicone rubber tube can be determined according to shaping mould.
Embodiment
Used silicone rubber tube 1 is an exotic material, external diameter 8mm, wall thickness 1mm.Need when making mould on the die joint of shaping mould one side, to make " Ω " type groove in advance, silicone rubber tube 1 is placed in the groove, with bolt mould is carried out matched moulds with alignment pin then and be connected, adapter coupling 2 is fixed on the two ends of mould.Adapter coupling 2 adds the steel components of structure for machine, and an end has the joint of tapering, and there is the external screw thread of M24 the back, reach 20mm, and the joint rear end is a square flange, has four through holes above, is used to install and fix screw.Is a Φ 8 through holes in the middle of the joint, silicone rubber tube 1 can be translated on the tapering face of joint front end after by this hole.Gland 3 is a steel revolving parts, and an end has the internal thread that matches with the M24 external screw thread of adapter coupling 2, and the other end is a M12 external screw thread, middle hollow-core construction for the band tapering surface of revolution.This part screws by the M24 external screw thread with adapter coupling 2, silicone rubber tube 1 flange crush seal can be lived.One-way cock 4 is a finished product, and an end has the M12 internal thread and is connected with the end of thread of gland 3, and the other end is the quick-release structure, can be connected fast with loading line.When not being connected with loading line, check valve keeps sealing state, then unidirectional opening when being connected with loading line, and pressed gas enters into silicone tube by this valve.Because the check valve of the other end is in self-styled state, so the time pressure in the silicone tube sealing system raise, silicone tube is expanded, tightly fit with the mould die joint, thereby mould is divided into inside and outside two parts pressure area, and after adopting vacuum bag will spread mould that layer product finish to seal, the zone of vacuum bag inside is sealing area like this, can finish vacuum pumping, thereby finish vacuum pressed problem composite products.
Using method of the present invention is: the silicone rubber tube of sealing system is installed in " Ω " type groove of branch half hitch structure die body, mould is carried out matched moulds to be connected, again adapter coupling 2 is fixed on the two ends of mould, glue pipe socket on joint, is installed gland 3, one-way cock 4 then successively, loading line 5 is connected on the one-way cock 4 of an end, open source of the gas, in loading line 5, charge into the pressed gas of 0.5MPa, silicone rubber tube is expanded, so just realize the sealing of sub-half-mold tool die joint.
