Problems solved by technology

[0005] One of the main disadvantages of this kind of injection molding machine is: since the mold clamping cylinder is set under the disc, in order to complete the mold clamping and delay pressure maintaining work, the piston of the mold clamping cylinder must move from the bottom to the top of the mold clamping hole of the disc. out and higher than the disk until the mold is pressed against the storage cylinder, but in order not to affect the normal rotation of the disk, the distance between the piston of the mold clamping cylinder and the storage cylinder above the disk is relatively long. That is, the stroke of the mold clamping cylinder piston is relatively long, so it takes a long time for this type of injection molding machine to complete an injection molding work, and the production efficiency is low

The described rotary disk device includes rotatable circular disk and drive device for driving circular disk and making it be rotated; The described injection moulding device includes horizontal pre-injection mechanism and vertical injection mechanism; and the mould-closing device includes a mould-closing hydraulic cylinder over the circular disk. Said invention also provides its working principle and operation method.

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 plastic injection. The molding machine injects and molds the molds with the same style and different code numbers in stages, and facilitates the mold opening and taking out the molded soles. [0003] Chinese patent 00229774.4 discloses a disc type injection molding machine for producing plastic shoe soles, including screw pre-molding mechanism, injection mechanism, mold clamping mechanism, hydraulic energy storage system and turntable part; The material end is connected with a switching seat equipped with a s...
