As shown in Figure 1, the utility model provides the injecting molding die 100 of a kind of oil field compression type packer tubling, for the sulfidization molding of compression type packer tubling, with injection (mo(u)lding) machine (not shown on figure) with the use of; Injecting molding die 100 is provided with pressurize mould 1, patrix 2, middle mould 3 and counterdie 4 from top to bottom successively; Middle mould 3 has the circular inner wall adapted with packing element outer wall shape, and the top and bottom of middle mould 3 seal with counterdie 4 with patrix 2 respectively and contact; Be arranged in mould 3 and be also coaxially provided with module 5 between patrix 2 and counterdie 4, interior module 5 has cylindrical outer wall, the external diameter of interior module 5 is less than the internal diameter of middle mould 3, the top and bottom of interior module 5 seal with counterdie 4 with patrix 2 respectively and contact, and form the annular die cavity 6 adapted with packing element shape between patrix 2, counterdie 4 and middle mould 3 inwall and interior module 5 outer wall; The upper surface of patrix 2 seals with pressurize mould 1 and contacts, and pressurize mould 1, patrix 2, middle mould 3, interior module 5 and counterdie 4 are by being connected hold-down mechanism compact siro spinning technology together; Pressurize mould 1 is provided with first injection channel 11 of accepting and injecting sizing material, and patrix 2 is provided with the second injection channel 21 be communicated with annular die cavity 6, is provided with the clearance portion 7 of connection first injection channel 11 and the second injection channel 21 between pressurize mould 1 and patrix 2; Clamping mechanism connectivity part being blocked or be communicated with is provided with in clearance portion 7 and the connectivity part of the first injection channel 11.
Concrete, as shown in Figure 1, Figure 3 and Figure 4, clamping mechanism comprises locked mode ring 8, locked mode post 9 and flexible member 10; Locked mode ring 8 is annular element (as shown in Figure 3), and the sidewall of locked mode ring 8 is evenly distributed with multiple open-work 81, and locked mode ring 8 is arranged between pressurize mould 1 and patrix 2, and the first injection channel 11 is communicated with clearance portion 7 by open-work 81; Locked mode post 9 is cylindrical, and what locked mode post 9 slided up and down is set in locked mode ring 8, and the open-work 81 on locked mode ring 8 is closed or opens by the sidewall of locked mode post 9; As shown in Figure 4, patrix 2 is provided with the through hole 22 adapted with locked mode post 9 external diameter, and locked mode post 9, through through hole 22, is provided with flexible member 10 between locked mode post 9 and interior module 5; Locked mode post 9 bottom outer wall is provided with stopper section 91.
Operation principle of the present utility model is: enter in the first injection channel 11 of pressurize mould 1 from injection nozzle 99 sizing material out; During original state, locked mode post 9 is stable under the effect of flexible member 10 and stopper section 91 is positioned at the position closed by the open-work 81 on locked mode ring 8; The sizing material entered in the first injection channel 11 heads on locked mode post 9 downwards, when downward power is greater than the elastic force of flexible member, sizing material forces locked mode post 9 to move down, after locked mode post 9 is moved down into the open-work 81 exposing locked mode ring 8, sizing material is entered in clearance portion 7 by open-work 81, and enters in annular die cavity 6 by the second injection channel 21 of patrix 2; Injection sizing material is stopped after annular die cavity 6 is full of and reaches certain pressure; the connectivity part of clearance portion 7 and the first injection channel 11 is blocked by clamping mechanism; namely locked mode post 9 moves up under the elastic force effect of flexible member 10; be returned to the position closed by the open-work 81 of locked mode ring 8, ensure that the pressure in die cavity 6 and then guarantee continuation sulfidation.Because pressurize mould 1, patrix 2, middle mould 3, interior module 5 and counterdie 4 are by being connected hold-down mechanism compact siro spinning technology together, formed moveable overall, therefore the dull and stereotyped (not shown) of this entirety from injection (mo(u)lding) machine can be taken out, put into baking oven and continue sulfuration, put a set of pressurize mould 1, patrix 2, middle mould 3, interior module 5 and counterdie 4 linked together in addition simultaneously, carry out the injection moulding of next packing element.Set up 5-6 die assembly like this and form circulation process, constantly substitute, significantly can heighten production efficiency.
Further, injecting molding die is also provided with and is connected to upper positioning disk 17 in the upper and lower dull and stereotyped (not shown) of injection (mo(u)lding) machine and lower positioning disk 18 by bolt, nut; Upper positioning disk 17 is provided with the central through hole 171 coordinated with injection nozzle 99; Lower positioning disk 18 is provided with location indentations 181, and counterdie 4 is positioned at location indentations 181.The upper flat plate of injection (mo(u)lding) machine is connected with upper positioning disk 17 bolt, thus plays positioning action, and injection nozzle 99 is inserted in the central through hole 171 of positioning disk 17, plays a protective role to injection nozzle, also serves the effect of flow guiding disc in addition; The entirety that pressurize mould 1, patrix 2, middle mould 3, interior module 5 and counterdie 4 are connected to form is by positioning in the location indentations 181 of counterdie 4 on lower positioning disk 18.
Further, as shown in Figure 1, the circumferential contact surface between middle mould 3 and counterdie 4, interior module 5 and upper and lower mould 2,4 is inclined-plane, is beneficial to aligning and being separated between each die assembly, to rise in mold process can convenient, more save time, the working time in the middle of shortening.The symmetrical both sides of counterdie 4 outside are fixedly installed jug 15, and handle can be welded on counterdie, contribute to the carrying of mould.Second injection channel 21 is the multiple up big and down small conical through-hole (as shown in Figure 4) along the distribution of patrix even circumferential; In order to increase elastic force, flexible member 10 comprises an outer spring and an inner spring.
Further, pressurize mould, patrix, middle mould and counterdie all have circumferential outer wall; Connect hold-down mechanism and comprise screw bolt and nut, as depicted in figs. 1 and 2, pressurize mould, upper die and lower die exterior periphery are evenly equipped with four corresponding bolts hole 19, and bolt passing through bolt hole is connected with nut check.
From the above mentioned; the utility model is by arranging clamping mechanism; realize the maintenance to mold cure pressure; runner is closed while sizing material has mobility; mould is made to be provided with moveable condition; the remaining most of cure time of mould can be allowed to transfer in baking oven complete, save the service time of injection (mo(u)lding) machine, increased substantially production efficiency.And the structural design of mould is conducive to placement, the installation and removal of mould, save the time of molding, ensure the yield rate of packing element.
The foregoing is only the schematic detailed description of the invention of the utility model, and be not used to limit scope of the present utility model.Any those skilled in the art, equivalent variations done under the prerequisite not departing from design of the present utility model and principle and amendment, all should belong to the scope of the utility model protection.
