Description

Hollow style forming apparatus and forming method of blow molding machine}

The present invention relates to a hollow body forming apparatus and a molding method of a blow molding machine, and more particularly, the ram is raised together with the discharge tube while extruding the material to produce a parison from the inlet mold upwards In order to prevent the tensile force from working in the process, and by realizing a structure in which a certain amount of material required for forming the product is injected into the discharge pipe and extruded into the ram, the functionality of the device according to the material supply method is greatly improved. The present invention relates to a hollow body molding apparatus and a molding method of blow blow molding machine.

Blow molding machines are generally used for mass production of hollow products made of rubber or plastic, which is usually the method of pulling the parison from the nozzle upwards before the molding. It is applied.

Therefore, when the parison is pulled out, deformation due to the tensile force becomes thin and the molding state becomes unstable, but it acts as a factor that decreases the life of the product. Recently, in order to prevent the deformation of the thickness due to the tension, the molding method has been diversified. There is a trend.

Meanwhile, referring to FIGS. 1A, 1B, and 1C, a conventional apparatus for manufacturing a plastic hollow body having a slide mandrel, which is a conventional patent registration No. 10-92305, first, the nozzle unit 2, which is a fixed body, has an opening 10. It is configured while forming the upper end, and the conical portion (3) for cutting the lower end of the segment 36 while being lifted by the cylinder inside the nozzle portion 2 is coupled, the compressed air passage inside the conical portion (3) The mandrel 30 forming the phosphorus pipe 6 is coupled to the cylinder device 31 while slidingly coupled.

At this time, a passage 9 through which the plastic 34 to be injected is provided between the nozzle portion 2 and the conical portion 3. An exit device 13 which pulls up the segment 36 while lifting up and down by a cylinder is positioned above the nozzle part 2, and the head part 35 of the injected segment 36 is located at the bottom of the exit device 13. Inflow grooves 16 are formed.

In addition, the exit device 13 penetrates the groove 16 while being fitted with a pipe 25 forming a passage of the compressed air 28.

On the outside of the nozzle unit 2 and the evacuation apparatus 13, a pair of mold units 19 for forming the segments 36 are disposed to face each other, so as to be movable forward and backward.

Referring to the operation of the conventional technology configured as described above are as follows.

First, when the plastic 34 is supplied through the raw material supply part while the exit device 13 is seated on the top of the nozzle part 2, the plastic 34 is a passage provided between the nozzle part 2 and the conical part 3. Passing through the opening (9) through the opening 10 is introduced into the groove 16 of the exit device 13 to form a head portion 35.

After the evacuation device 13 rises to a predetermined position and stops thereafter, the plastic 34 is continuously discharged through the opening 10 and upwardly along the exit device 13 to form a hollow segment 36. Is formed on the nozzle portion 2, and at the same time, the evacuation device 13 is raised in a state in which the head portion 35 is embedded in the groove 16. As shown in FIG.

Afterwards, the oppositely disposed molds 19 move forward to face each other to contain the segments 36, and at the same time, the pipes 6 formed on the mandrel 30 and the pipes 25 of the exit device 13 are disposed. Through the compressed air is simultaneously supplied to the hollow side of the segment (36).

Therefore, the segment 36 is formed to be in close contact with the inner surface while being opened toward the mold portion 19, and then the supply of the compressed air is stopped and the mold portion 19 is returned to its original position.

Then, when the gripper advances and grasps the formed segment 36, the exit device 13 is raised while separating the head 35, and at the same time the cone 3 is lifted by the cylinder. The upper end part cuts the lower end part of the segment 36 on the opening part 10, which causes the segment 36 to move freely on the nozzle part 2.

After that, the gripper is separated from the nozzle unit 2 while holding the segment 36, and at the same time, the exit device 13 is lowered to repeat the same process as described above.

In the conventional technique as described above, since the exit device 13 is pulled up while pulling the segment 36, the middle portion of the segment 36 becomes thin due to the deformation of the tensile force. As a result, when the middle portion of the segment 36 is formed into an uneven shape, the molding state becomes unstable, and thus the quality of the product is significantly reduced.

Another problem is that the structure of supplying the plastic 34 necessary for forming the segment 36 in the air continuously, when the heating device is turned off, the plastic 34 remaining on the passage is cured. The discomfort associated with the removal of 34) significantly reduces the functionality of the device.

First, the raw material (plastic plastic material) is put into the hopper 74 (see FIG. 2), and then the start button is turned on through the operation unit 94 (see FIG. 6), and the control unit 92 commands to turn on the heater 76. (S1)

Therefore, the heater 76 (see FIG. 2) is sufficiently heated so that the material introduced into the hopper 74 can pass in a state of good fluidity, and this heat is transferred to the discharge pipe 46.

After the step S1, the control unit 92 (see FIG. 6) transmits an on and off command to the screw motor 68, and a rising and stopping command of the lifting cylinder 20 rod 22, respectively (S2).

When the screw motor 68 (see Fig. 2) is operated by the command transmitted from the control unit 92 as described above, the screw shaft 70 rotates to move the material in the hopper 74, wherein the material is As it moves along the guide tube 72, it is heated by the heater 76, and fluidity becomes favorable.

Thereafter, the material is injected into the discharge pipe 46 through the guide hole 64 as shown in FIG. 8A.

When the material is injected into the discharge tube 46, the ram 58 is raised, the guide hole 64 is opened, the rod 56 of the adjustment cylinder 54 is lowered to discharge tube 46 The outlet of the nozzle 48 installed at the lower part is closed, and the amount of material to be injected is to fill the space as much as "L" which is the extrusion range of the ram 58.

As described above, since the material injected from the supply unit 66 is directly supplied to the discharge pipe 46 by a limited amount required for molding, there is no remaining material, and when the heater 76 is turned off and on, Most of the material staying in the guide tube 72 is heated by the heater 76 to have fluidity.

Therefore, the functionality of the device according to the material supply method is significantly improved.

In addition, the lifting cylinder 20 (see Fig. 4) is operated by the command of the control unit 92 (see Fig. 6) to raise the rod 22 so that the nozzle head 18 enters the inlet forming part 24. do.

After the step S2, the control unit 92 (see Fig. 6) transmits the reverse rotation on, off command to the servo motor 90 (S3).

When the servo motor 90 constituting the elevating portion 78 (see FIG. 2) provides the reverse rotational power by the command transmitted from the controller 92 as described above, the power passes through the gearbox 88 and the screw shaft. While reaching 86, the bed 80 is lowered as shown in FIG. 8B, which causes the slider 82 installed on both sides of the bed 80 to move downward along the guide rail 84.

Therefore, the supply unit 66 installed on the bed 80 is lowered together, and at the same time, the discharge tube 46 connected to the tip of the guide tube 72 of the supply unit 66 is lowered. The nozzle 48 installed at the lower part is in contact with the upper surface of the inlet mold 10, and a part of the upper side of the nozzle head 18 is accommodated in the groove 57 formed at the lower end of the rod 56.

After the step S3, the control unit 92 (see Fig. 6) is a command for raising and stopping the rod 56 of the adjustment cylinder 54, the command for lowering and stopping the ram 58 of the supply cylinder 60, and the servomotor. A forward rotation on and off command of 90 is transmitted, respectively (S4).

When the rod 56 of the adjustment cylinder 54 is raised and stopped by the command transmitted from the controller 92 as described above, as shown in FIG. 8C, the lower portion of the rod 56 is the outlet of the nozzle 48. Will open.

After the above, when the supply cylinder 60 is operated by the command of the control unit 92 (see FIG. 6), the rod 62 (see FIG. 3) lowers the ram 58, which causes the ram 58 to be lowered. Is lowered along the rod 56 of the adjustment cylinder 54 to extrude the material filled in the discharge pipe 46 to the inlet mold 10 (see Fig. 5) located below.

In the above state, when the servo motor 90 of the elevating unit 78 (see FIG. 2) provides the forward rotational power by the command of the control unit 92 (see FIG. 6), the power is applied to the gear box 88. The bed 80 is raised as shown in FIG. 8D while reaching the screw shaft 86, and the slider 82 installed at both sides of the bed 80 moves upward along the guide rail 84. do.

Therefore, the supply unit 66 installed on the upper portion of the bed 80 is raised together, and at the same time, the discharge tube 46 connected to the tip of the guide tube 72 of the supply unit 66 is raised. The nozzle 48 installed at the lower portion of the) rises apart from the top surface of the inlet mold 10.

When the discharge pipe 46 is raised as described above, the ram 58 is continuously lowered to extrude the material, so that the material to be extruded as described above is the parison (2) in the upward direction from the inlet forming portion (24) In this case, since the parison 2 is not a pull-out method but is generated in an upward direction, the thickness deformation does not occur due to the tensile force not acting on the parison 2.

Thus, molding the product 4 with the parison 2 results in a good product 4 of uniform thickness.

The height of the parison 2 (refer to FIG. 5) is such that the inlet mold 10 extends from the inlet mold 10 to the upper end of the body forming portion 19 formed in the first and second move molds 12 and 14.

After the step S4, the control unit 92 (see Fig. 6) transmits the forward and stop commands of the rod 38 of the mold cylinder 36. (S5)

When the mold cylinder 36 is operated by the command transmitted from the controller 92 as described above, as shown in FIG. 8E, as the rod 38 moves forward, the second move mold 14 moves toward the inlet mold 10. In this case, the guide cylinder 30 is pulled while the mold cylinder 36 and the fixed plate 40 move backward in proportion to the distance that the second move mold 14 is advanced.

Accordingly, the guide shaft 30 pulls the first move mold 12 toward the inlet mold 10 by a distance proportional to the moving distance of the second move mold 14 while moving horizontally in the other direction.

At this time, the pinions 32 and 34 installed below the first and second move molds 12 and 14 are moved while rotating along the rack 42 coupled with the gears, and the first and second move molds 12 and 14 are moved. Is moved toward the inlet mold 10 to face each other while containing the parison 2 into the body forming portion 19, at the same time the nozzle 48 of the discharge pipe 46 is the first, second move mold (12,14) is in contact with the top.

As described above, when the second move mold 14 is advanced by the mold cylinder 36, a device in which the oppositely disposed first move molds 12 are adjacent or spaced at the same distance at the same time is generally referred to as a synchronization device.

After the step S5, the control unit 92 (see Fig. 6) transmits an on, off command to the air pump 26 (S6).

When the air pump 26 is operated by the command transmitted from the controller 92 as described above, and compressed air is supplied through the nozzle head 18 as shown in FIG. 8F, the compressed air is inside the parison 2. It is supplied to the to raise the pressure, so that the parison 2 in the flow state is opened to the outside by the increased internal pressure, each body forming part 19 formed on the front of the first and second move molds (12, 14) ) Close to the inner surface.

Thus, the parison 2 is made in the form of the product 4 to be molded.

After the step S6, the control unit 92 (see Fig. 6) transmits the command to lower and stop the rod 56 of the adjustment cylinder 54. (S7)

When the adjustment cylinder 54 is operated and the rod 56 is lowered as described above, the upper end of the parison 2 is closed while closing the outlet of the nozzle 48 as shown in FIG. 8G. Will cut.

After the step S7, the control unit 92 (see Fig. 6) transmits a forward rotation on, off command to the servo motor 90 (S8).

As described above, when the servo motor 90 (see FIG. 2) provides the forward rotational power by the control unit 92 command as described above, the supply unit 66 and the discharge tube 46 are raised as shown in FIG. 8H. As shown in the drawing, the nozzle 48 provided at the lower portion of the discharge pipe 46 is spaced apart from the upper end of the first and second move molds 12 and 14 to return to its original position.

After the step S8, the control unit 92 (see FIG. 6) transmits the reverse and stop commands of the rod 38 of the mold cylinder 36 and the lower and stop commands of the rod 22 of the lifting cylinder 20, respectively. (S9)

When the mold cylinder 36 is operated by the control unit 92 command as described above and the rod 38 is reversed as shown in FIG. 8I, the first and second move molds 12 and 14 are reversed as described above. It is separated from the inlet mold (10).

Accordingly, the body forming part 19 of the first and second move molds 12 and 14 is separated from the product 4 and at the same time, the pinions 32 and 34 installed under the first and second move molds 12 and 14. Moves along the rack 42 and returns to its original position.

If the rod 22 is lowered while the elevating cylinder 20 is operated by the command of the control unit 92 (see FIG. 6) in the above state, the nozzle head formed on the top of the rod 22 (see FIG. 8I) ( 18 is positioned below the inlet mold 10 to be separated from the inlet forming part 24.

As a result, the product 4 is separated from the first and second move molds 12 and 14, and the nozzle head 18 to support the local area is separated, thereby freeing the movement.

After the step S9, the control unit 92 (see Fig. 6) transmits an on, off command to the carrying member 43. (S10)

As described above, the gripper 44 constituting the discharging member 43 enters the inlet mold 10 by the command of the controller 92 to hold the product 4 and move it to the outside.

Thus, the molding process of one product 4 is finished.

After the step S10, the control unit 92 (see Fig. 6) determines whether or not the end mode. (S11)

If it is determined that the control unit 92 is not in the end mode, the control unit 92 returns to step S1 and repeats the above operation.

After the step S11, if it is determined that the controller 92 is in the end mode, the controller 92 transmits an off command to the heater 76 (S12).

As described above, when the heater 76 is turned off by the command of the controller 92, the material is no longer heated, and thus the molding operation becomes difficult because the material is no longer fluidized.

Thus, the actual molding operation is finished.
