Problems solved by technology

[0005] One of the main disadvantages of this kind of plastic injection molding machine is: since the mold clamping cylinder is set under the disk, in order to complete the mold clamping and delay pressure maintenance work, the piston of the mold clamping cylinder must be moved from the bottom to the mold clamping hole of the disk. Eject out and exceed the disc until the mold is pressed against the storage cylinder. At the same time, after the injection molding is completed, but in order not to affect the normal rotation of the disc, the piston of the mold clamping cylinder must be moved from the top to the bottom. The mold clamping hole of the disc is completely lowered, resulting in a long stroke of the mold clamping cylinder piston, and it takes a long time to move from the beginning to the process that does not affect the normal rotation of the disc, resulting in low production efficiency

Embodiment 1

[0040] 1 to 7 show a first embodiment of the present invention. Wherein, Fig. 1 is a schematic view of the first structure of the present invention; Fig. 2 is a view to A of Fig. 1; Fig. 3 is a view to B of Fig. 1; Fig. 4 is a partially enlarged schematic view at C in Fig. 1; Fig. 5 is a view of Fig. 4; Figure 6 is a schematic structural view of the injection head in Figure 1; Figure 7 is a schematic structural view of the injection nozzle in Figure 1.

[0041] See Fig. 1 to Fig. 3, this embodiment is a kind of monochromatic vertical disc plastic injection molding machine, comprises turntable device 1, injection device 2 and clamping device 3; Said turntable device 1 comprises rotatable disc 11, A fixed stand 15 for lifting the disc 11 and a drive device 12 for driving the disc 11 to rotate, the drive device 12 can be driven by an electric motor or a hydraulic motor; the injection device 2 Including injection frame 21 and vertical pre-molding mechanism 22, injection cylinder ...

Embodiment 2

[0057] 8 to 10 show a second embodiment of the present invention. Among them, Fig. 8 is a schematic diagram of the second structure of the present invention; Fig. 9 is a view taken along the direction D of Fig. 8; Fig. 10 is a schematic diagram of the structure of the injection nozzle in the vertical disc plastic injection molding machine shown in Fig. 8 .

[0058] This embodiment is basically the same as Embodiment 1, the difference is: see Fig. 8 to Fig. 9, the vertical disc plastic injection molding machine of this embodiment is no longer equipped with a spare oil cylinder, but the injection plate 214 is fixedly arranged In the middle of the column 213.

[0059]See Fig. 10, in addition, the discharge channel 24321 in the injection nozzle in this embodiment is a groove arranged on the outer surface of the discharge part 2432 along the vertical direction.

[0060] The working process of this embodiment is the same as that of Embodiment 1, except that when maintaining and cle...

Embodiment 3

[0062] Figure 11 shows a third embodiment of the present invention.

[0063] This embodiment is basically the same as Embodiment 1, the difference is that, as shown in Figure 11, the turntable device 12 also has a fixed position relative to the mold clamping frame 31 during injection molding, that is, when the injection head is pressed against the mold. The pressure-bearing tray 13 for supporting the disc 11 is used to lift the disc 11 and be higher than the pressure-bearing tray 13 during non-injection molding, that is, when the injection head is no longer pressed against the mold. There are two elastic standoffs 14 and four rigid fixed standoffs 15 on the upper surface of the tray 13 .

[0064] In the vertical disc plastic injection molding machine of this embodiment, when the disc 11 is not pressed downward by the injection head 24, the elastic standoff 14 lifts the disc 11 up and out of the The upper surface of the pressure-bearing tray 13 is 2 mm to 5 mm, so that the rot...

Abstract

The prevention discloses a vertical disk plastic injection molding machine and includes a dial device, an injection device and a molding device. The dial device comprises a rotary disk and a drive device driving the rotation of the rotary disk. The injection device comprises an injection rack and a vertical preplasticizing device, an injection fuel tank and an injection head arranged on the injection rack. The molding device comprises a molded rack and a molded fuel tank positioned on the molded rank and under the disk. A molded fuel tank piston can be moved up and down. The molded fuel tank piston and the injection head is fixedly connected through the injection rack. The molded fuel tank piston drives the injection head to do the up-and-down movement through the injection rack. The invention can reduce a travel path of the molded fuel tank piston, reduce the travel time and thereby, and effectively enhance the production efficiency.

Description

technical field [0001] The invention belongs to a plastic injection molding machine, in particular to a disc type plastic injection molding machine. Background technique [0002] Disc type plastic injection molding machine is a kind of equipment specially used for manufacturing plastic soles. The discs used are often equipped with multiple sole molds of the same style and different sizes at the same time. Therefore, it is necessary to set the molds on the turntable for plastics. The plastic injection molding machine injects and molds molds with the same style and different code numbers in stages, and facilitates the process of opening the mold and taking out the molded sole. [0003] Chinese patent 00229774.4 discloses a disc-type plastic injection molding machine for producing plastic shoe soles, including a screw pre-molding mechanism, an injection device, a mold clamping device, a hydraulic energy storage system and a turntable part; the pre-molding screw is horizontally ...
