Description

Technical Field

[0001] The utility model belongs to the field of hot runner molds, and specifically relates to a hot runner mold manifold. Background Art

[0002] The manifold is also called the hot runner mold manifold. The manifold can make the mold cavity evenly filled, the plastic flow balanced, and the system heat balanced.

[0003] A Chinese patent with publication number CN215921160U discloses an injection hot runner manifold for precision molds, including an upper manifold and a lower manifold. The bottom of the upper manifold is tightly fitted with the lower manifold, the outer wall of the pull rod is slidably connected to the lower manifold through a slide groove, one end of the pull rod is fixedly connected to a fixed block, the bottom of the fixed block is slidably connected to the lower manifold through a slide groove, the top of the fixed block is fixedly connected to a first bayonet, and the outer wall of the first bayonet is tightly fitted with the second bayonet. Although the above-mentioned hot runner manifold is coordinated between the pull rod, the first pin and the second pin, when the internal flow channel is blocked, the user pulls the two pull rods on the left side toward the middle, and the pull rod drives the fixed block to move toward the middle. The fixed block compresses the spring and drives the first pin to move, so that the first pin and the second pin are separated, which solves the problem that the injection molding hot runner manifold for precision molds is inconvenient to disassemble when the internal flow channel is blocked. However, when assembling the upper manifold and the lower manifold, it is necessary to pull the two pull rods on the left and right sides at the same time, and then place the upper manifold on top of the lower manifold, and then loosen the two pull rods on the left and right sides to assemble. At least two people are required to operate, and the operation steps are cumbersome, which affects work efficiency.

[0004] In view of this, the present utility model is proposed. Utility Model Content
