Detailed Description
In order to make the technical means, the creative features, the objectives and the functions of the present invention easily understood and appreciated, the present invention will be further described with reference to the specific drawings, and in the description of the present invention, it should be noted that unless otherwise specified and limited, the terms "mounted," "connected" and "connected" should be understood broadly, for example, they may be fixedly connected, detachably connected, integrally connected, mechanically connected or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements.
Example 1
As shown in fig. 1, a cutting head structure for use in an injection mold includes: stub bar 1, plastic product 2, cutter 3, cutter panel 4 and cutter bottom plate 5, high-pressure spring 6, spacing face 7, piston 8 and hydraulic cylinder 9, be equipped with cutter 3 below stub bar 1 and the plastic product 2, 3 lower parts of cutter are located inside cutter panel 4, 4 upper portions of cutter panel are equipped with spacing face 7, 7 lower extremes of spacing face are equipped with high-pressure spring 6, high-pressure spring 6 is located cutter 3 one side, 6 lower extremes of high-pressure spring connect inside cutter bottom plate 5, 5 lower parts of cutter bottom plate are equipped with piston 8, hydraulic cylinder 9 is connected to 8 lower extremes of piston.
Furthermore, the plane of the cutting knife 3 is 0.08mm flat.
Example 2
As shown in fig. 1, a cutting head structure for use in an injection mold includes: stub bar 1, plastic product 2, cutter 3, cutter panel 4 and cutter bottom plate 5, high-pressure spring 6, spacing face 7, piston 8 and hydraulic cylinder 9, be equipped with cutter 3 below stub bar 1 and the plastic product 2, 3 lower parts of cutter are located inside cutter panel 4, 4 upper portions of cutter panel are equipped with spacing face 7, 7 lower extremes of spacing face are equipped with high-pressure spring 6, high-pressure spring 6 is located cutter 3 one side, 6 lower extremes of high-pressure spring connect inside cutter bottom plate 5, 5 lower parts of cutter bottom plate are equipped with piston 8, hydraulic cylinder 9 is connected to 8 lower extremes of piston.
Furthermore, the plane of the cutting knife 3 is 0.08mm flat.
Further, the high-pressure spring 6 is in threaded connection with the inside of the cutter bottom plate 5.
Further, the cutter face plate 4 and the cutter bottom plate 5 are in threaded connection.
Furthermore, one side of the lower end of the cutter 3 is provided with a limiting corner 3.1.
Furthermore, a through hole 4.1 is formed in the cutter panel 4, and the shape of the through hole is matched with that of the lower end of the cutter 3.
The utility model discloses the theory of operation does: in the process of starting injection molding, the hydraulic oil cylinder 9 is not started, the side glue inlet is in an open state, the product is normally injected and molded, after pressure maintaining or before cooling of the product, high-pressure oil is started to push the hydraulic oil cylinder 9 to move upwards, and the hydraulic oil cylinder 9 pushes the cutter panel 4 and the cutter base plate 5 to integrally move upwards. The high-pressure spring 6 is stressed enough and gradually in a compressed state, when the cutter panel 4 moves to the designed limiting surface 7 and stops, the cutter 3 moves upwards by 1mm at the moment, and the flat position of 0.08mm on the cutter surface of the cutter 3 just collides with the rear mold core to separate the product from the runner and block the contact with the product, so that the cutting-off function in the product mold is realized. When the die opening signal is sent by the die, the hydraulic oil cylinder 9 stops supplying oil, the high-pressure spring 6 is not stressed and starts rebounding to drive the whole structure of the cutter 3 to retreat and be in the initial state.
