The present invention aims to provide a kind of pipe hoop of transmitter, transmitter and preparation method thereof, can make the connection of support portion on transmitter and transmitter body closely, firmly, damping and material-saving.Below in conjunction with drawings and Examples, the present invention is described in detail.
Shown in Fig. 1 and 5, structure of a kind of pipe hoop of transmitter of the embodiment of the present invention and preparation method thereof,
23 is pipe collar body; 28 is the hole on pipe collar body, is located between outer surface 29 and inner peripheral surface 33, for damping and saving material, does not destroy its Joint strenght again.29 is cambered surface; 28 can be the various cavity or the hole that are located at outer surface and transmitter body contacts face, do not destroy its Joint strenght again for damping and material-saving.
Method for making comprises step:
S10, the metal insert of annular is put into the die cavity of mould;
First by the metal insert of annular, as the ironware of annular, steel part, alloy steel piece or copper piece etc., the die cavity of injection machine mould is put into, then mold closing.
S11, in the die cavity of described mould, inject the shock proof injection raw material of melting as polypropylene or poly-carbon etc.;
Polypropylene GRANULES is added feeding cylinder from hopper, polypropylene GRANULES is under the effect of screw rod, be fed forward and compacting along screw channel, polypropylene GRANULES little by little plastifies under the double action of external heat and screw rod shearing, melting and homogenizing, when screw rod rotates, the polypropylene of melting is shifted onto the head of screw rod, meanwhile, screw rod retreats under polyacrylic counteraction, screw head is made to form storing space, complete plasticizing process, then, screw rod is under the effect of the piston thrust of injection cylinder, with high speed, high pressure, by the melt polypropylene in storage compartment by nozzle injection in the die cavity of mould.
S12, pressurize and cooling are carried out to the polypropylene of melting in described mold cavity, form the tubular transmitter body with described metal insert;
The polypropylene of melting in described mold cavity, after pressurize, cooling, solidifying and setting, forms the tubular transmitter body with described metal insert.
S13, around described metal insert, inject melting wear-resisting if to have elasticity better as polyurethane or rubber etc.;
S14, pressurize and cooling are carried out to the polyurethane of described melting, form the support portion of described tubular transmitter body.
About the concrete injection molding process of polypropylene and polyurethane in the present embodiment, identical with the injection molding process of polyurethane with polypropylene in prior art, do not repeat them here.
Due to the physicochemical property of polypropylene and polyurethane itself, method not by melting makes the two directly closely be combined as a whole, the method for making of transmitter of the present invention, first form the tubular transmitter body with metal insert, then around described metal insert, inject the polyurethane of melting, and pressurize and cooling are carried out to the polyurethane of described melting, form the support of described tubular transmitter body.Make described polyurethane by described metal insert closely and be connected to securely on described transmitter body like this.
Further, in order to make the combination of polyurethane and metal insert more closely with firm, inject the polyurethane of melting around described metal insert before, be included in the step of the exterior periphery coating cementing medium of described metal insert.
In one embodiment of the invention, the injection moulding of described polypropylene and polyurethane carries out in different moulds.Therefore in this embodiment, comprise after described step S12:
S120, open described mould, take out the tubular transmitter body with described metal insert;
In a mould, injection mo(u)lding is carried out to polypropylene, formed after being embedded with the tubular transmitter body of described metal insert, take out the tubular transmitter body with described metal insert.
S121, the described tubular transmitter body with metal insert is put into the die cavity of another mould.
The described tubular transmitter body with metal insert is put into the die cavity of another mould, so that inject the polyurethane of melting around described metal insert.
S122, in the die cavity of another mould described, around described metal insert, inject the polyurethane of melting.
Certain polyurethane also can adopt cast liquid polyurethane in mold cavity, and then heating and thermal insulation is shaping.
In figure 6,30 is seal ring, is located at the two ends of pipe collar 23, for improving sealing effectiveness.
In another embodiment of the present invention, the injection moulding of described polypropylene and polyurethane is carried out in same mould.The time of die change can be saved like this, improve operating efficiency.Described mould comprises the first die cavity and the second die cavity; Wherein said first die cavity is used for polyacrylic injection mo(u)lding, and described second die cavity is used for the injection mo(u)lding of polyurethane.In order to form spaced and be arranged in parallel two support portions on described transmitter body, described second die cavity is two, spaced and be arranged in parallel.
In this embodiment, the die cavity that the described metal insert by annular puts into mould is specially: the first die cavity metal insert of annular being put into mould;
Correspondingly, the polypropylene injecting melting in the die cavity of described mould is specially: the polypropylene injecting melting in the first die cavity of described mould;
Correspondingly, the polyurethane injecting melting around described metal insert is specially: the polyurethane injecting melting in the second die cavity of described mould.
The embodiment of the present invention also provides a kind of transmitter, and the support component on it can be made to be combined with transmitter body closely with firm.
Referring to shown in Fig. 2 to Fig. 4, the present embodiment transmitter, comprising:
