Embodiment 2

[0036] see Figure 4 , the movable shutter is applied in the mold with nozzle plate 9 in the present embodiment, and its working procedure is as follows:

[0037] 1. Mold closing:

[0038] 1.1. The first mold clamping: lower the movable template 6 and close the fixed template 7. At this time, the movable shutter that is movable in the movable template 6 is pushed up by the fixed template 7, so that the resin shutter 1 is embedded in the In the opening at the bottom of the movable template 6, and the position-limiting end at the lower end of the positioning rod 2 is in conflict with the upper wall of the opening at the bottom of the movable template 6 to realize positioning. Align the opening on the right side of the kernel to complete the first mold closing;

[0039] 1.2. The second mold closing: the panel 8 is lowered and the nozzle plate 9 is mold-closed. At this time, the lower end of the slider 10 connected to the bottom of the panel 8 is embedded in the opening in the m...

Abstract

The invention provides a movable shutter, and relates to the technical field of mold accessories. The movable shutter movably penetrates in a movable mold plate, and comprises a resin shutter body, apositioning rod, a meson, a first screw and a second screw; the upper end of the resin shutter body is fixedly connected with the positioning rod through the first screw; and the meson is fixed at theupper end of the positioning rod through the second screw. The movable shutter is movably arranged on a movable mold, a mold opening and closing operation sequence of the mold is controlled, it effectively ensures that mold core drawing mechanisms do not collide and products cannot be pulled when discharged from the molds, the quality of the products is improved effectively, and the practicalityis high.

Description

technical field [0001] The invention relates to the technical field of mold accessories, in particular to a movable shutter. Background technique [0002] Resin shutters are also called nylon clamps, resin mold clamps, nylon resin shutters, etc. The resin shutter is a part that adjusts the friction between the template and the nylon sleeve by locking the tapered bolt. [0003] The current resin shutter is fixedly installed on the moving platen. During the mold closing process, the slider insert collides with the rear mold core. When the mold is opened, the slider insert pulls the product and causes product damage, which needs to be improved urgently. Contents of the invention [0004] The object of the present invention is to aim at the defects and deficiencies of the prior art, to provide a movable switch with simple structure, reasonable design and convenient use, which is installed on the movable mold to control the operation sequence of mold opening and mold closing ...
