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 of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: a die stripping device for metal castings comprises a top plate 1 supported by a support frame 10, the support frame 10 is positioned on two sides of the top plate 1, the support frame 10 is welded on two sides of the top plate 1, a bidirectional motor 3 is installed in the middle position inside the top plate 1, such as an existing RC360 micro motor in the market, after a power supply is connected, output shafts at two ends of the top plate can synchronously rotate and can realize positive rotation and reverse rotation of the output shafts, the output shafts on two sides of the bidirectional motor 3 are connected with first screw rods 2 through a coupling in a transmission way, power transmission between the output shaft of the bidirectional motor 3 and the first screw rods 2 is ensured through the coupling, a sliding groove 101 is formed in the bottom end face of the top plate 1, a second screw rod 6 is slidably connected in the sliding groove 101, the first screw rod 2 penetrates through the second screw rod 6, a threaded sleeve 7 is sleeved on the outer side of the second screw rod 6, a module 8 is, the output shaft at 3 both ends of two-way motor passes through the shaft coupling and drives first screw rod 2 and rotate, according to the screw thread transmission principle, drive second screw rod 6 and remove in spout 101, it is the right triangle-shaped form to play 8 vertical cross-sections of module, in the gap between mould and the bed die is gone up in the most advanced tip embedding of triangle-shaped angle, second screw rod 6 through both sides drives two vertical ends that play module 8 and moves in the center department of going up mould and bed die gradually, thereby make the gap between last mould and the bed die bigger and bigger, it is ejecting from the bed die to go up the mould, make the metal casting deviate from in last mould, again with metal part take out can, moreover, the steam generator is simple in structure, and convenient for operation, the mode of having avoided through crow bar or hammering plays the mould, the protection mould does not receive the damage, the life of extension mould.
Specifically, as shown in fig. 1 to 3, the penetration portions of the first screw rod 2 and the second screw rod 6 are connected through threads, according to the thread transmission principle, the second screw rod 6 can move on the first screw rod 2 through the rotating first screw rod 2, the second screw rod 6 is connected with the thread sleeve 7 through threads, according to the thread transmission principle, by rotating the thread sleeve 7, on one hand, the position of the mold stripping block 8 on the second screw rod 6 can be adjusted, step-by-step mold stripping is performed on the multilayer casting mold, the upper mold and the middle mold are ejected out of the lower mold, and a metal casting is convenient to take out, on the other hand, before use, the mold stripping block 8 can be rotated between the second screw rod 6 and the support frame 10, so that the mold stripping block 8 is prevented from being accurately placed under the top plate 1 to perform mold stripping.
Specifically, as shown in fig. 1 to 3, the sliding groove 101 and the second screw 6 are in clearance fit, so that on one hand, the second screw 6 can be limited to rotate along with the first screw 2, and the second screw 6 can only move horizontally in the sliding groove 101, and on the other hand, when the second screw 6 moves in the sliding groove 101, the second screw 6 is prevented from shaking due to unstable movement of the second screw 6 because the mold stripping module 8 is subjected to resistance when moving to a gap between the upper mold and the lower mold.
Specifically, as shown in fig. 1-3, a plurality of rollers 9 are disposed on the triangular slope of the mold lifting block 8, so that the mold lifting block 8 can enter the gap between the upper mold and the lower mold, and the resistance of the mold lifting block 8 in the gap between the upper mold and the lower mold is reduced, thereby accelerating the mold lifting process and improving the working efficiency.
Specifically, as shown in fig. 1-3, a power box 5 is installed on the top end face of the top plate 1, a control switch 4 is electrically connected to the outer side of the power box 5, the bidirectional motor 3, the control switch 4 and the power box 5 are electrically connected, a loop is formed among the bidirectional motor 3, the control switch 4 and the power box 5 through electric wires, the power box 5 provides power for the bidirectional motor 3, and the control switch 4 can control the start and stop of the bidirectional motor 3.
The working principle is as follows: when in use, firstly, the screw sleeve 7 is screwed in to ensure that the screw sleeve 7 is positioned between the second screw rod 6 and the support frame 10, then the whole die drawing device is placed right above a die to be drawn, then the screw sleeve 7 is continuously screwed in to ensure that a small part of the tip with the minimum angle of the die drawing module 8 is embedded into a gap between the upper die and the lower die according to the thread transmission principle, the two-way motor 3 is started through the control switch 4 to ensure that the output shafts at the two ends of the two-way motor 3 rotate positively, the output shaft of the two-way motor 3 drives the first screw rod 2 to rotate through the coupler, according to the thread transmission principle, the second screw rod 6 moves inwards in the sliding groove 101, the die drawing module 8 moves in the gap between the upper die and the lower die along with the gradual movement of the second screw rod 6 to the center of the die, the length of the vertical end of the die drawing module 8 is gradually increased, thereby the gap between the upper die, thereby ejecting the upper die from the lower die, facilitating the taking out of the metal casting, and after the stripping is finished, closing the control switch 4 and closing the bidirectional motor 3; before use, whether the second screw rods 6 on two sides are located at the outermost end of the sliding groove 101 or not is checked, if not, the bidirectional motor 3 is started, output shafts at two ends of the bidirectional motor are enabled to rotate reversely, and the second screw rods 6 are moved to the outermost end of the sliding groove 101 according to the thread transmission principle.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
