The specific embodiment
Below in conjunction with accompanying drawing, provide preferred embodiment of the present utility model, and described in detail, enable to understand better function, the characteristics with the bumper injection mold that plays pin mechanism of the present utility model.
As shown in Figures 2 and 3, the utlity model has the bumper injection mold that plays pin mechanism and comprise pulling block 10, lower drawing block 20, upper connecting rod 12, lower link 22 and oblique top 30, upper connecting rod 12 is fixed on a side of pulling block 10, and lower link 22 is fixed on a side of lower drawing block 20.Be provided with first mounting groove 11 in the last pulling block 10, in first mounting groove 11, be provided with first and play pin mechanism.Lower drawing block 20 is provided with second mounting groove 21 and step 201, and step 201 is provided with second and plays pin mechanism on the top of lower drawing block 20 in second mounting groove 21.First plays pin mechanism comprises that first plays pin 311, first spring 312 and first holder 313, first spring 312 is enclosed within first and plays on the pin 311, first bottom that plays pin 311 is fixed on first holder 313, and the diameter of first holder 313 is greater than the diameter of the first bullet pin 311.Second plays pin mechanism comprises that second plays pin 321, second spring 322 and second holder 323, second spring 322 is enclosed within second and plays on the pin 321, second bottom that plays pin 321 is fixed on second holder 323, and the diameter of second holder 323 is greater than the diameter of the second bullet pin 321.Product 5 comprises first flanging 51 and second flanging 52, and during matched moulds, first plays the below that pin 311 is resisted against second flanging 52, and second plays the below that pin 321 is resisted against first holder 313, and first flanging 51 is between last pulling block 10 and lower drawing block 20.Oblique top 30 has the ccontaining fluting 31 of going up pulling block 10 and lower drawing block 20, wherein, the lower surface of fluting 31 is inclined-plane 32, inclined-plane 32 is lower near near the angle the opening of fluting 31, preferably, inclined-plane 32 angle the best with respect to the horizontal plane is that second holder 323 is resisted against on the inclined-plane 32 about 30 degree.Above-mentioned inclined-plane 32 angle with respect to the horizontal plane also can be not more than 50 degree at most greater than 30 degree.If exceed this angular range, run into second during this face return and play pin 321 and may not upwards hit second on the contrary and play pin 321 and it is severed block in the top playing pin, promptly when the entire mechanism return, cause easily to play pin and block locked.
As shown in Figure 3, the die sinking process that the utlity model has the bumper injection mold that plays pin mechanism is as follows: in the die sinking operation, oblique top 30 moves to right-hand, because inclined-plane 32 is on oblique top 30, this moment, oblique top 30 moved to right, inclined-plane 32 and lower drawing block 20 have produced the gap, the power that the second bullet pin 321 is subjected to second spring 322 moves downward, originally the second bullet pin 321 heads on first and plays pin 311, the first bullet pin 311 is used for the hole on moulding second flanging, play this moment second and can't withstand the first bullet pin 311 after pin 321 moves downward, and first play the power that pin 311 is subjected to first spring 312 and also move downward, so from second flanging, deviate from, upper connecting rod 12 hauls pulling block 10 and leaves second flanging fully along moving to right then, relative lower link 22 is pushing away lower drawing block 20 and is withstanding product not allow product turn right moving, and after going up pulling block 10 by the time and leaving the second flanging zone, product just can upwards be ejected by the ejecting mechanism of mould.In the time of return, oblique top 30 is to left side motion, and last pulling block 10 moves to the left side, because the effect on inclined-plane 32 plays upwards top of pin 321 to second, the second bullet pin 321 plays pin 311 with first and also upwards pushes up, and the first bullet pin, 311 quilt tops put in place static, are used for the hole on moulding second flanging.The utility model solves prior art single bullet pin when two flangings are arranged and is difficult to reach under the situation of demoulding product, need not change shape of product and the successful demoulding.
Above-described, be preferred embodiment of the present utility model only, be not in order to limiting scope of the present utility model, the foregoing description of the present utility model can also be made various variations.Be that every simple, equivalence of doing according to the claims and the description of the utility model application changes and modification, all fall into the claim protection domain of the utility model patent.The utility model not detailed description be the routine techniques content.
