Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

The embodiment of the present invention as shown in fig. 1 to 5 provides a die for trimming forged parts, which comprises an upper die holder 1, a base 7, and a crude casting product 9, wherein an upper die core 2 is fixedly installed at the bottom of the upper die holder 1, and a guide sleeve 3 is fixedly installed at the bottom of the upper die holder 1;

the improved guide sleeve structure is characterized in that a lower die holder 6 is fixedly mounted at the top of the base 7, a lower die core 5 is fixedly mounted at the top of the lower die holder 6, a guide pillar 4 is fixedly mounted at the top of the lower die holder 6, the guide pillar 4 is movably sleeved inside the guide sleeve 3, and a collecting box 8 is placed at the top of the base 7.

As shown in fig. 2 to 5, an upper limit column 11 is fixedly installed on the bottom surface of the upper die holder 1, an upper pressure groove 21 is formed on the bottom surface of the upper die core 2, a positioning column 22 is fixedly installed on the bottom of the upper die core 2, a lower pressure groove 51 is formed on the top of the lower die core 5, a positioning hole 52 is formed on the top of the lower die core 5, a lower limit column 61 is fixedly installed on the top of the lower die holder 6, the position of the upper limit column 11 corresponds to the position of the lower limit column 61, the size of the positioning column 22 matches with the size of the positioning hole 52, the position of the upper pressure groove 21 corresponds to the position of the positioning hole 52, the crude casting 9 includes a finished casting 91, burrs 92 are fixedly connected to the outside of the finished casting 91, an inclined square block 911 is fixedly sleeved in the middle of the finished casting 91, circular holes 912 are formed on both sides of the top surface and the bottom surface of the finished casting 91, the size of the upper pressure groove 21 matches with the size of the crude casting 9, and the size of the lower pressure groove 51 matches with the size of the finished casting 91;

specifically, at first place foundry goods crude 9 at the top of indent 51, then die core 2 whereabouts is gone up in the whereabouts drive of upper die base 1, reference column 22 slides in the inside of locating hole 52, guide pin bushing 3 slides in the outside of guide pillar 4 simultaneously, then go up die core 2 and the extrusion of lower die core 5 and cut off finished product foundry goods 91 and deckle edge 92, then finished product foundry goods 91 drops from indent 51 down, it is collected to fall into in collecting box 8, upper limit post 11 makes the upper die base 1 whereabouts stop with the touching of lower limit post 61 at last, make outside deckle edge once amputate, time is saved, production efficiency is promoted, and the consumptive material is reduced simultaneously.
