Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, in an embodiment of the present invention, a T-iron part mold structure for a car horn includes: the die comprises an upper die holder 1 and a bottom die holder 2, when the die is used, the upper die holder 1 is fixed on a sliding block at the top of a punch press, the bottom die holder 2 is fixed on a workbench below the punch press, an upper die 3 is installed below the upper die holder 1, a bottom die 4 is installed above the bottom die holder 2, a thimble 5 is arranged on the bottom die 4, a cushion block 6 is arranged below the thimble 5, an ejection mechanism 7 is arranged below the cushion block 6, the upper die 3 and the bottom die 4 jointly form a die cavity, the die cavity is cylindrical, the radius of the die cavity is 100 mm, the thimble 5 is positioned below the die cavity, a material to be forged and pressed is placed in the die cavity, the thimble 5 abuts against the lower part of the material to limit the material, the height of the material in the die cavity can be adjusted by adjusting the cushion block 6, and after the material enters the die cavity, enough vertical height can be reserved to ensure that the next, after the material is placed into the die cavity, the punch is started to forge and press the material, the material can deform according to the die cavity under the action of forging and pressing equipment to obtain the required size, an extruding process after turning the column base is not needed, the production efficiency and the quality are improved, and the production cost and the delivery cycle of the product are reduced.

The mold-entering angle R a of the mold cavity is 5mm in radius, the proper mold-entering angle R can improve the fluidity of the material and enable the material to be extruded into the mold cavity more easily, the mold-entering angle b of the mold cavity is 73 degrees and is suitable for the mold-entering angle, under the condition of ensuring that the material smoothly and stably enters a die cavity, the phenomena of surface crack, material overlapping and the like in the next deformation process are not caused, the traditional process of extruding after turning a column base by machining has long production period, great variation, unstable quality and low material utilization rate, the process of extruding and necking adopted by the utility model greatly improves the production efficiency and the material utilization rate, stabilizes the product quality, reduces the production cost and the probability of product variation, ensures that the product has stronger competitiveness, and after the forging and pressing are finished, the ejection mechanism 7 can eject the material formed by forging and pressing out of the die cavity, so that the product can be smoothly demoulded.
