Detailed Description
The technical solution provided by the present invention is explained in more detail with reference to fig. 1 to 3.
As shown in fig. 1, the utility model discloses a tripping device with five section type guide rails 3, it includes: the inner side of the front mould 1 is provided with a back-off area of the front mould 1 matched with the back-off outer side of the product; the inclined ejecting component 2 comprises an inclined ejecting block and an inclined ejecting rod, and the inclined ejecting rod is used for pushing the inclined ejecting block to move upwards and inwards;
the five-section guide rail 3 is divided into five sections, namely a first section 31, a second section 32, a third section 33 and a fourth section 34 which are connected in sequence; the end of the first section 31 is arranged obliquely towards the center of the mould, the second section 32 is arranged vertically, the end of the third section 33 is arranged obliquely towards the center of the mould, and the end of the fourth section 34 is arranged obliquely towards the center of the mould; the fifth section 35 is vertically arranged;
the push rod assembly 4 is arranged in the inclined top assembly 2, the push rod assembly 4 comprises a push rod 41 and a pull block 42, one end of the push rod 41 is matched with the five-section type guide rail 3, and the other end of the push rod 41 is connected with the pull block 42; the pulling block 42 is provided with a projection 421 inserted with the buckling position 51 on the product; the push rod 41 moves along the five-section type guide rail 3 to pull the product to be separated from the back-off area of the front mold 1.
The utility model discloses a tripping device with five section formula guide rails 3 is applicable to the injection mold who makes the injection molding that has the back-off part, like household electrical appliances shell, automobile parts etc. in this embodiment interior parting bumper is the example, explains the utility model discloses a tripping device's concrete structure.
The utility model discloses a dropout structure passes through push rod assembly 4 and removes along five section formula guide rails 3, thereby pulls out the product deformation from the back-off region of front mould 1 with the product, and the product can break away from the mould smoothly. Wherein when the push rod 41 moves along the first section 31 of the five-section guide rail 3, the pulling block 42 pulls the product to deform towards the inner side of the mold; when the push rod 41 moves along the second section 32 of the five-section type guide rail 3, the inclined ejector block moves towards the inner side of the mold so as to be separated from the inner wall of a product; when the push rod 41 moves along the third section 33 of the five-section type guide rail 3, the pull block 42 pushes out a product, so that the reverse buckling position 51 of the product is separated from the inclined ejecting block;
when the push rod 41 moves along the fourth section 34 and the fifth section 35, the lifter continues to move towards the inner side of the mold, so that the lifter does not interfere with the back-off of the internal parting bumper, and the internal parting bumper is smoothly ejected out of the mold. The fourth section 34 is set to be in a shape that the tail end inclines towards the center of the mold, namely the fourth section 34 is consistent with the inclination direction of the lifter rod, so that the relative movement of the lifter and the pull block 42 can be slowed down, and the pull injury of the reversed buckle part caused by the lifter can be avoided.
The end part of the push rod is provided with a groove, and the five-section type guide rail is embedded into the groove, so that the push rod can move along the five-section type guide rail.
The angle of inclination of the fourth section 34 is less than the angle of inclination of the pitched roof. Because when push rod 41 is followed during the walking of four-section type guide rail, simultaneously the oblique top is along the incline direction inward movement of oblique ejector pin, if the inclination of fourth section 34 is greater than the inclination of oblique ejector pin, draw the piece 42 can with the chucking in the oblique top outside, the dead condition of oblique top subassembly 2 and push rod subassembly 4 card appears. Preferably, the fourth section 34 is inclined at an angle α of 2 ° ≦ α ≦ 5 °. Through a plurality of experiments, the inventor finds that when the inclination angle of the fourth section 34 is alpha and alpha is more than or equal to 2 degrees and less than or equal to 5 degrees, the phase speed of the pulling block 42 and the inclined top is reduced, and the product has no pull injury phenomenon.
Similarly, the inclination angle of the first section 31 is smaller than that of the oblique mandril. Because when push rod 41 is followed during the walking of five section formula guide rails 3, simultaneously the oblique top is along the incline direction inward movement of oblique ejector pin, if the inclination of first section 31 is greater than the inclination of oblique ejector pin, draw the piece 42 can with the chucking of the oblique top outside, the dead condition of oblique top subassembly 2 and push rod subassembly 4 card appears. Preferably, the difference between the inclination angle of the first segment 31 and the inclination angle of the oblique mandril is 1-4 degrees.
