Problems solved by technology
At present, the swing hook type mold opening sequence controller is often used. This commonly used swing hook type mold opening sequence controller has poor reliability in action, and its dimensions vary with different molds. It is difficult to install and adjust, and it is difficult to achieve standardization.

Embodiment Construction
[0016] Such as figure 1 refer to figure 2 As shown, the present invention is a novel mold opening sequence controller, which is mainly composed of a pull rod 1, a pull rod fixing block 2, a pull rod limit block 3, a dial pin 4, a swing rod 5, a swing rod fixing seat 6, and a pin shaft 7 And spring 8 composition.
[0017] The upper part of the tie rod 1 is fixed on the upper first template (panel) 10 of the mould, and its lower part has a boss 11, and the two sides of the boss 11 along the longitudinal direction are slopes 12; the tie rod fixing block 2 It is fixed on the upper second template 20 of the mould, and there is a parting surface between the first template 10 and the second template 20 .
[0018] In order to make the upper end of the swing rod 5 engage with the upper end surface of the tie rod fixing block 2, a convex edge must be provided on the upper part of the swing rod 5. This convex edge can be directly processed on the upper part of the swing rod 5, or a pu...

The invention discloses a novel mould opening sequence controller which is mainly composed of a draw bar, a draw bar fixed block, a draw bar stop block, a dial pin, an oscillating bar, an oscillating bar permanent seat, a pin roll and a spring. The invention is characterized in that the round dial pin passing through the upper end of the oscillating bar is mutually abutted with a boss with an inclined plane on the lower part of the draw bar so as to separate the projecting edge of the upper end of the oscillating bar from the draw bar fixed block. Because the dial pin is a cylinder and the boss of the lower part of the draw bar is provided with a slope, the dial pin and the boss have smooth contact and reliable and stable action after being abutted and do not have action dead point. In addition, because the lower part of the oscillating bar is sheathed in the U-shaped groove of the oscillating bar permanent seat, the controller does not horizontally swing, so that action precision and reliability are higher.
Description
technical field [0001] The invention relates to a mold accessory, in particular to a novel mold opening sequence controller. Background technique [0002] Plastic injection molds are tools for producing plastic products and are widely used. In the injection molding of plastic products, in order to meet the needs of the molding process, the opening sequence of the mold parting surface should be controlled. When the mold has two parting surfaces, it must be opened in a certain order according to the requirements of the molding process. Therefore, it is necessary to control the mold opening forces on different parting surfaces so that the mold with the smaller mold opening force should be opened first. The parting surface is opened, and then the parting surface with a larger mold opening force is opened to facilitate the removal of the pouring system aggregate and plastic products from the mold. At present, the swing hook type mold opening sequence controller is often used. T...
