Description

Technical Field

[0001] The utility model relates to the technical field of plastic injection molding machines, and particularly relates to a plastic injection molding machine which is convenient to adjust. Background Art

[0002] A plastic injection molding machine, also called a plastic injection forming machine or a plastic injection machine, is the main molding equipment for making various shaped plastic products by using a plastic molding die with thermoplastic or thermosetting materials, and is divided into vertical, horizontal, and all-electric types. The plastic injection molding machine can heat the plastic, apply high pressure to the molten plastic, and eject it to fill the mold cavity. The position of the feed inlet of the plastic injection molding machine is usually fixed. When pouring the material in the container into the feed inlet, due to the height difference between the container and the feed inlet, the material is likely to spill out, which is not conducive to feeding. Therefore, a plastic injection molding machine which is convenient to adjust is proposed to facilitate the entry of the material. Summary of the Utility Model

[0003] Aiming at the problems in the prior art, the utility model provides a plastic injection molding machine which is convenient to adjust.

[0004] The technical solution adopted by the utility model to solve its technical problems is a plastic injection molding machine which is convenient to adjust, including an injection molding machine body. A feed hopper is arranged at the feed inlet of the injection molding machine body. A sleeve is arranged in the feed hopper. An auxiliary feeding member is arranged in the sleeve. Clamping seats are fixed on both sides of the feed hopper. Blocks are fixed on both sides of the sleeve. Vertical rods are fixed at the bottom ends of the two blocks. Through grooves adapted to the vertical rods are formed on both clamping seats. A handle is hinged on the sleeve. A pull rod is arranged below the handle. Through holes for the ends of the pull rod to pass through are formed on both clamping seats. Limit blocks are fixed at both ends of the pull rod. Two springs are sleeved on the pull rod. Two inserting rods are fixed on the pull rod. Through holes for the ends of the inserting rods to pass through are formed on both clamping seats. A plurality of slots adapted to the inserting rods are formed on the side walls of the two vertical rods.

[0005] By adopting the above technical solution, pulling the pull rod drives the two inserting rods to move horizontally, the ends of the two inserting rods are disengaged from the two vertical rods, holding the handle to lift the sleeve, and after releasing the pull rod, the two springs push the two limit blocks to reset, and the ends of the two inserting rods are inserted into the slots on the side walls of the two vertical rods, so that the height of the sleeve can be adjusted according to the height of the container, which is conducive to the entry of the material.

[0006] Specifically, a plurality of support columns are fixed on the feed hopper, and the bottom ends of the plurality of support columns are connected to the injection molding machine body.

[0007] By adopting the above technical solution, the setting of the support columns improves the stability of the feed hopper.

[0008] Specifically, the auxiliary feeding member includes a motor and a support. The motor is fixed to the top of the support. Cross bars are fixed to both sides of the support, and both cross bars are connected to a sleeve. The output shaft of the motor penetrates through the support and is connected to a vertical rod through a coupling.

[0009] A sleeve is sleeved on the bottom end of the vertical rod. An adjusting bolt is provided below the support. A threaded hole adapted to the adjusting bolt is formed in the side wall of the sleeve, and a plurality of slots adapted to the adjusting bolt are formed in the side wall of the vertical rod. A spiral blade is fixed to the sleeve.

[0010] The output shaft of the motor drives the vertical rod to rotate, and the sleeve and the spiral blade rotate therewith, which can prevent materials from accumulating in the feed hopper and causing the materials to fail to smoothly enter the injection molding machine body. Loosen the adjusting bolt and pull out the sleeve, and screw the end of the adjusting bolt into the slot in the side wall of the vertical rod, so that the height of the spiral blade can be adjusted as needed.

[0011] Specifically, a conical protective cover is fixed to the top of the motor.

[0012] By adopting the above technical solution, the protective cover can protect the motor and prevent materials from accumulating on the top of the motor during feeding.

[0013] Specifically, the feed hopper is welded to two clamping seats, and both the two stoppers are welded to the sleeve.
