Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Examples

As shown in fig. 1, the high-speed steel roll resin sand molding static pressure demolding device comprises a base 10 arranged on a horizontal ground, wherein a hydraulic machine 20 and a mold groove 30 are arranged at the top of the base 10, the hydraulic machine 20 is fixedly arranged at one end of the mold groove 30, a limiting wall 31 is arranged at the other end of the mold groove 30, the hydraulic machine 20 is arranged horizontally, a telescopic rod of the hydraulic machine 20 and the mold groove 30 are coaxially arranged, and a push disc 21 is fixedly arranged at the tail end of the telescopic rod of the hydraulic machine 20.

As shown in fig. 2, a mold 1 for molding the resin sand of the high-speed steel roll is cylindrical, a hoisting arm 3 is arranged on the outer wall of the mold, a coaxial inner core 2 is arranged in the center of the mold, one end of the inner core 2 protrudes out of the mold 1, and when the mold is manually demolded, the protruding end is placed on the ground and then the top of the mold 1 is knocked by a hammer, so that the outer mold 1 and the inner core 2 are separated by vibration. In this embodiment, be used for placing mould 1 through setting up mould groove 30, set up spacing wall 31 simultaneously and replace ground and play spacing effect, then utilize the flexible drive of hydraulic press 20's telescopic link to push away dish 21 and push the external mold of mould 1 to spacing wall 31, make mould 1's external mold and inner core 2 produce the separation, the utility model discloses a hydraulic press 20 hydraulic pressure force realizes the drawing of patterns, and is high-efficient and safe, and the drawing of patterns in-process is the static pressure drawing of patterns, has avoided the tremble and the noise of hammering.

In this embodiment, as shown in fig. 1, the groove wall of the mold groove 30 is arc-shaped. The arc-shaped die groove 30 is higher in degree of attachment with the die 1, so that the die 1 is not stably placed and swayed during demolding.

In addition, as shown in fig. 1, the arc degree of the mold groove 30 is less than 180 degrees and greater than 150 degrees. Because the additional wall of the die 1 is provided with symmetrical hoisting arms 3, when the die is hoisted to the die groove 30, in order to take out the hoisting chain, a gap needs to flow out between the hoisting arms 3 and the top of the die groove 30.

In this embodiment, as shown in fig. 1, a bull eye bearing 32 is fixedly mounted on a wall of the mold groove 30. Because mould 1 is too big in addition inside roll quality, can produce very big frictional force with between the cell wall in mould groove 30, be unfavorable for the drawing of patterns, through setting up bull's eye bearing 32, reduce the area of contact of mould 1 and mould groove 30 and reduce frictional force, utilize the rolling performance of bull's eye bearing 32 itself simultaneously, further reduce frictional force to improve the smoothness nature of drawing of patterns.

In this embodiment, as shown in fig. 1, a buffering device 33 is further fixedly mounted on the limiting wall 31, and the buffering device 33 includes a bearing plate 331 and a buffering spring 332 fixed between the bearing plate 331 and the limiting wall 31. After the die 1 is demolded, because the thrust of the hydraulic press 20 can impact the limiting wall 31, the impact limiting wall 31 can damage the limiting wall 31, the service life of the device is shortened, impact noise can be generated, and the buffering device 33 is arranged, so that the die 1 can be demolded and cannot be in direct contact with the limiting wall 31 through the buffering of the buffering spring 332, the limiting wall 31 is protected, and noise is avoided.

As shown in fig. 1, the carrier plate 331 is semi-circular. Since the inner core 2 of the mold 1 needs to abut against the limiting wall 31, the bearing plate 331 is designed to be a semicircular structure, so that the inner core 2 of the mold 1 can contact with the limiting wall 31 from above the bearing plate 331.

In this embodiment, as shown in fig. 3, the cross section of the push plate 21 is circular. In this way, the inner core 2 of the mold 1 may be positioned inside the push plate 21, and the push plate 21 is in contact with only the outer mold of the mold 1, thereby separating the inner core 2 of the mold 1 from the outer mold.
