Detailed Description

The technical solution of the present invention will be further described with reference to fig. 1 to 5 by way of specific embodiments.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

A mold convenient for demolding, which comprises a top mold 1 and a bottom mold 2,

the top die 1 is a female die, a profiling concave part 1a is arranged in the middle of the front surface of the top die 1, and a locking part 1b is arranged in the middle of the back surface of the top die 1; the middle part of the locking part 1b is further sunken, the sunken shape is a cone-shaped funnel 1c, and the large caliber of the funnel 1c is positioned at the bottom of the locking part 1 b;

as shown in fig. 4, the top die 1 is provided with a plurality of groups of curved channels 1 d; the tube body of the channel 1d is arranged in the top die 1; the inlet of the channel 1d is communicated with the bottom of the funnel 1c, the outlet of the channel 1d is arranged on the surface of the profiling recess 1a, and the channel 1d is communicated with the funnel 1c and the profiling recess 1 a;

the bottom die 2 is a male die, and the middle part of the front surface of the bottom die 2 is provided with a profiling bulge 2 a; the profiling protrusion 2a is matched with the profiling recess 1 a.

When a fan mold is pressed, iron sheets are usually placed in the mold, the iron sheets are pressed through the cooperation of the top mold 1 and the bottom mold 2 to form a finished fan blade, and then the finished fan blade is taken out. But because the thickness of flabellum is thinner, can produce in the in-process of suppression, the iron sheet has received the suppression deformation and has produced the heat to the inflation card is in the die. When the finished product is clamped on the female die, manual intervention is needed, and the production efficiency is greatly influenced. In order to solve the problem, the top die 1 is internally provided with a plurality of groups of channels 1d and funnels 1c, and lubricating liquid can be filled into the funnels 1c in the using process; preferably, an inorganic lubricating fluid should be selected, the surface tension of the inorganic lubricating fluid being greater than the surface tension of the organic lubricating fluid; the lubricating liquid flows to the surface of the profile recess 1a with the passage 1 d. Because the lubricating liquid is sticky, when the lubricating liquid flows to the outlet of the channel 1d, the lubricating liquid stays at the outlet of the channel 1d due to the surface tension of the liquid, when the die is pressed, the iron sheet contacts the outlet of the channel 1d, the surface tension of the lubricating liquid is broken, the lubricating liquid flows to the surface of the profiling concave part 1a and covers the iron sheet, the lubricating liquid can absorb part of heat, the expansion of the iron sheet is reduced, the profiling concave part 1a can be lubricated, and the die demoulding is facilitated. When the pressing die is stopped, clean rags are used for wiping off the lubricating liquid on the surface of the profiling concave part 1a, so that the lubricating liquid generates surface tension at the outlet of the channel 1d again, and the lubricating liquid is prevented from flowing out all the time.

Preferably, the channel 1d is a circular channel 1d, and the diameter of the channel 1d is between 1mm and 3 mm.

The circular structure is a symmetrical structure, so that when the lubricating liquid contacts the outlet of the channel 1d, the generated surface layer is more uniform and is not easy to break.

The diameter of the channel 1d is set to be 1 mm-3 mm most suitably; if the diameter of the passage 1d is larger than this interval, first, it is possible that the surface tension is reduced because the surface layer of the lubricating liquid is drawn up at the outlet of the passage 1 d. The outflow of the lubricating fluid cannot be effectively controlled, resulting in the waste of the lubricating fluid. If the diameter of the passage 1d is smaller than this interval, the lubricant will not be stuck in the passage 1 d.

Preferably, the locking part 1b is a square groove body; the four walls of the square groove body are provided with a plurality of groups of locking holes 1ba, and the locking holes 1ba are provided with threads.

The locking part 1b has two functions, the first function is used for sealing the lubricating liquid poured into the funnel 1 c; secondly, a machine is needed to lift the top die 1 in the process of producing and pressing. The hoisting device is inserted into the locking part 1b and extends out of a screw to be screwed into the locking hole 1ba, so that the hoisting device and the top die 1 are fixed.

Preferably, the top die 1 and the bottom die 2 are rectangular dies, and through holes 1e are formed in four corners of the rectangular dies; four corners of die block 2 all are provided with cylinder 2b, cylinder 2b with through-hole 1e phase-match.

Through-hole 1e and cylinder 2b between correspond each other when the top mould 1 falls, the device of whereabouts only need aim at through-hole 1e cylinder 2b, and location die block 2 that just can be accurate can not take place the skew at the in-process of suppression.

Preferably, the middle part of the bottom die is provided with an air pressure hole 2 c; the air pressure hole 2c is used for balancing air pressure during die pressing, and the air pressure hole 2c penetrates through the whole bottom die 2.

The in-process of suppression can be with the gaseous discharge in the mould for pressure in the mould reduces, inconvenient die sinking, sets up atmospheric pressure hole 2c can toward let in the air in the die block 2, makes the inside and outside atmospheric pressure of mould keep unanimous, has improved the efficiency of die sinking.

The technical principle of the present invention is described above with reference to specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without any inventive effort, which would fall within the scope of the present invention.
