Description

Technical Field

[0001] The utility model relates to the technical field of die casting production, in particular to an automatic material receiving device. Background Art

[0002] At present, in order to streamline the process, die casting is used to produce some metal parts. Die casting is a metal casting process that uses a pressure casting mechanical die casting machine equipped with a casting mold to pour heated liquid copper, zinc, aluminum or aluminum alloy metals into the inlet of the die casting machine. The die casting machine is die-cast to cast copper, zinc, aluminum or aluminum alloy parts of the shape and size limited by the mold. Such parts are usually called die castings.

[0003] After die-casting, the die-casting part needs to be taken out of the mold. The conventional method is to manually clamp the die-casting part out with a clamp. However, for the parts that have just been die-cast, their temperature is high and the parts have a certain weight. Manual operation is labor-intensive and there are certain safety hazards when facing high-temperature parts. In the vertical die-casting machine, a mechanical ejection method is used to take the material, that is, after the die-casting machine lifts the mold, the die-casting part is directly ejected from the mold and falls directly into the receiving tray below without manual clamping of the part. However, this method cannot control the falling height of the part. After the die-casting part falls, it will collide with the receiving tray, which is easy to cause damage to the die-casting part. In order to better complete the work of unloading and receiving the die-casting parts, a die-casting machine receiving device is needed. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model discloses an automatic material receiving device, and the technical solution adopted is that a telescopic slide is installed by a frame body that is tilted and fixed to support it. A material receiving basket is rotatably installed on the upper end of the telescopic slide, and the die-castings dropped from the die of the die-casting machine are received by the material receiving basket, and a cooling conveyor belt is correspondingly installed on the lower end of the telescopic slide. The upper surface of the cooling conveyor belt is lower than the lowest end of the inclined surface of the telescopic slide, so that the die-castings can slide onto the cooling conveyor belt through the telescopic slide and be transferred by the cooling conveyor belt. A bellows is fixedly connected to the upper part of the frame of the cooling conveyor belt, and a fan is installed on the bellows. The air outlet of the fan faces the upper surface of the cooling conveyor belt, so that the die-castings can be cooled by air during the conveying process. The cam is provided with a plurality of guide wheels, and the guide wheels are provided with a plurality of guide wheels, and the guide wheels are provided with a plurality of guide wheels respectively. A sliding connection column is fixedly connected to the lower inner side surface of the front end of the sliding slot, and the sliding buckle of the push-pull frame is installed on the sliding connection column, so that the sliding buckle of the push-pull frame is installed under the telescopic slide, and hook grooves are opened on both sides of the bottom of the fixed slide, and the push-pull frame corresponds to the hook grooves, and the push-pull frame is installed in meshing cooperation with the semi-gear teeth.

[0005] The bottom plate of the material receiving basket is evenly provided with air injection holes, and air injection heads are fixedly inserted in the corresponding air injection holes. Vertical columns are fixedly connected to the upper part of the bottom plate of the material receiving basket, and cross bars are fixedly connected between the vertical columns. Buffer blocking heads are linearly arranged and rotatably penetrated on the cross bars. The buffer blocking heads are arranged in two layers of upper and lower layers symmetrically on the material receiving basket, so that a buffer surface is formed by two rows of buffer blocking heads relatively arranged in the same horizontal plane. The upper and lower layers of buffer surfaces are designed, and the die-casting falls in the middle of the two rows of buffer blocking heads, which press the buffer blocking heads downward and rotate them. In the process of the die-casting falling through the two layers of buffer surface composed of the buffer blocking heads, the die-casting can be blocked and decelerated. A through hole is provided in the middle of the buffer blocking head, and the through hole is rotatably fitted and inserted into the cross bar. A blocking rod is fixedly connected to the front side of the buffer blocking head, and a buffer pad is wrapped on the blocking rod, and the buffer pad is made of high-temperature resistant cotton. A screw is fixedly connected to the rear side of the buffer blocking head, and a counterweight is threadedly connected to the screw. The position of the counterweight on the screw can be adjusted by rotating it, and it can also be removed, so that the inclination angle of the blocking rod can be adjusted by adjusting the position and number of the counterweight. When one side of the counterweight is heavier, it will cause one side of the barrier rod to tilt upward. At this time, if the die-casting wants to pass through the buffer surface, the downward pressing stroke of the barrier rod will be longer, thereby achieving a better blocking and deceleration effect, which can effectively buffer and decelerate the heavier die-casting. When one side of the counterweight is lighter, it will cause the barrier rod to tilt downward. At this time, it will be easier for the die-casting to press down on the buffer blocking head, allowing the die-casting to pass through the buffer surface more easily. The blocking and deceleration effect of the buffer surface is weakened, which can effectively buffer and decelerate the lighter die-casting, preventing the lighter die-casting from falling through the buffer surface composed of the buffer blocking head.

[0006] The cam is provided with a first latching platform and a second latching platform, and the first latching platform is provided with a second latching platform on the upper surface of the middle portion of the push-pull frame. The first latching platform is close to one end of the rack and higher than the second latching platform. The rear end of the push-pull frame is fixedly connected to a hook arm, and the upper surface of the end portion of the hook arm is fixedly connected to a hook. The sliding long hole is slidably buckled and connected to the sliding connection column, and the rack is meshed and installed with the semi-gear teeth. The upper surface of the hook arm is slidably attached to the lower surface of the fixed slide groove, and the hook and the hook groove are correspondingly buckled, and the upper surface of the second latching platform is attached to the lower surface of the sliding slide groove. After the sliding slide groove is retracted into the fixed slide groove, the second latching platform can be buckled and pressed on the front end surface of the fixed slide groove, and the rear side surface of the first latching platform corresponds to the front end surface of the sliding slide groove, so that the rear side surface of the first latching platform can be buckled and pressed on the front end surface of the sliding slide groove.

A bellows 701 is fixedly connected to the upper part of the frame of the cooling conveyor belt 7, and a fan 702 is installed on the bellows 701. The air outlet of the fan 702 faces the upper surface of the cooling conveyor belt 7, so that the die-castings can be cooled by air during the conveying process. The telescopic slide 2 includes a fixed slide 201 fixedly connected to the frame 1, and a sliding slide 202 is installed on the inner side of the fixed slide 201. Specifically, a buckle slide 207 is provided on the inner side of the fixed slide 201, and a slide rail 204 is fixedly connected to the outer side of the sliding slide 202. The slide rail 204 is installed in the buckle slide 207 corresponding to the sliding buckle. A linear drive rod 203 is fixedly connected to the middle position at the bottom of the fixed slide 201. The linear drive rod 203 uses a cylinder or an electric telescopic rod. The telescopic end is fixedly connected to the bottom of the sliding groove 202, so that the sliding groove 202 is driven to slide in the fixed groove 201 through the linear driving rod 203, and the sliding groove 202 drives the movement of the material receiving basket 3; a material receiving basket connecting shaft 205 is fixedly connected to the middle of the front end of the sliding groove 202, and a half gear 301 and a rotating connecting seat 305 are fixedly connected to the bottom of the material receiving basket 3. Concentric holes are opened at the center of the half gear 301 and the rotating connecting seat 305, and they are rotatably fitted and passed through the material receiving basket connecting shaft 205 on the telescopic slide 2.

[0021] The bottom plate of the receiving basket 3 is evenly provided with air jet holes 304, and an air jet head 5 is fixedly inserted in the air jet hole 304. The air jet head 5 includes a hollow box body 501. The bottom center of the box body 501 is connected to a connecting pipe 502, and an air pipe 503 is fixedly connected to the connecting pipe 502. The air jet head 5 is connected to the high-pressure air pump through the air pipe 503. The upper surface of the box body 501 is evenly arranged and fixedly connected with air jet nozzles 504. The high-pressure air flow generated by the high-pressure air pump enters the box body through the air pipe 503. 501, and are ejected through each air nozzle 504, the air nozzle 504 is connected to the inner cavity of the box body 501 and is plugged into the air hole 304 one by one, the upper end of the air nozzle 504 is located in the air hole 304, and is lower than the upper surface of the bottom plate of the receiving basket 3, the air nozzle 504 ejects air flow to form an upward air flow layer on the bottom plate of the receiving basket 3, and the falling die-casting will be buffered and decelerated by the air flow when it contacts the bottom plate of the receiving basket 3, thereby avoiding high-speed collision between the die-casting and the bottom plate.

[0022] A column 302 is fixedly connected to the upper part of the bottom plate of the receiving basket 3, and a cross bar 303 is fixedly connected between the columns 302. Buffer blocking heads 6 are linearly arranged and rotatably penetrated on the cross bar 303. The buffer blocking heads 6 are arranged in two layers of upper and lower layers symmetrically on the receiving basket 3, so that a buffer surface is formed by two rows of buffer blocking heads 6 arranged relatively to each other in the same horizontal plane. The upper and lower layers of buffer surfaces are designed. When the die-casting falls in the middle of the two rows of buffer blocking heads 6, the buffer blocking heads 6 are pressed down and rotated. In the process of the die-casting falling through the two layers of buffer surfaces composed of the buffer blocking heads 6, the die-casting can be blocked and decelerated. Specifically, a through hole 601 is provided in the middle of the buffer blocking head 6, and the through hole 601 is rotatably connected to the cross bar 303. A blocking rod 602 is fixedly connected to the front side of the buffer blocking head 6, and a buffer pad 605 is wrapped on the blocking rod 602. The buffer pad 605 is high-temperature resistant cotton. The die casting will contact the buffer pad 605 during the falling process to prevent the die casting from being damaged by the collision with the buffer blocking head 6. A screw rod 603 is fixedly connected to the rear side of the buffer blocking head 6, and a counterweight block 604 is threadedly connected to the screw rod 603. The counterweight block 604 can be rotated to adjust its position on the screw rod 603, or it can be removed, so that the inclination angle of the blocking rod 602 can be adjusted by adjusting the position and number of the counterweight blocks 604. When one side of the counterweight block 604 is heavier, it will cause one side of the blocking rod 602 to tilt upward. At this time, if the die-casting part wants to pass through the buffer surface, the downward pressing stroke of the blocking rod 602 will be longer, thereby achieving a better blocking and deceleration effect, which can effectively buffer and decelerate the heavier die-casting part. When one side of the counterweight block 604 is lighter, it will cause the blocking rod 602 to tilt downward. At this time, it will be easier for the die-casting part to press down on the buffer blocking head 6, allowing the die-casting part to pass through the buffer surface more easily. The blocking and deceleration effect of the buffer surface is weakened, which can effectively buffer and decelerate the lighter die-casting part, thereby preventing the lighter die-casting part from falling through the buffer surface formed by the buffer blocking head 6.

[0023] A sliding connection column 208 is fixedly connected to the lower inner side surface of the front end of the sliding slide 202, and hook grooves 206 are provided on both sides of the bottom of the fixed slide 201. The sliding buckle of the push-pull frame 4 is installed on the sliding connection column 208. Specifically, a sliding long hole 401 is provided in the middle of the side of the push-pull frame 4, and a rack 402 is fixedly connected to the front end of the push-pull frame 4. A first buckle platform 403 and a second buckle platform 404 are respectively provided on the upper surface of the middle of the push-pull frame 4. The first buckle platform 403 is close to one end of the rack 402 and is higher than the second buckle platform 404. A hook arm 405 is fixedly connected to the rear end of the push-pull frame 4, and a hook 406 is fixedly connected to the upper surface of the end of the hook arm 405. The sliding long hole 401 is slidably buckled and connected to the sliding On the connecting column 208, the rack 402 is installed in meshing engagement with the half gear 301, the upper surface of the hook arm 405 slides and fits against the lower surface of the fixed slide groove 201, the hook 406 corresponds to the hook groove 206, the upper surface of the second snap-in platform 404 fits against the lower surface of the sliding slide groove 202, the rear side surface of the second snap-in platform 404 corresponds to the front end surface of the fixed slide groove 201, after the sliding slide groove 202 is retracted into the fixed slide groove 201, the second snap-in platform 404 can be snap-in pressed against the front end surface of the fixed slide groove 201, the rear side surface of the first snap-in platform 404 corresponds to the front end surface of the sliding slide groove 202, so that the rear side surface of the first snap-in platform 404 can be snap-in pressed against the front end surface of the sliding slide groove 202.

[0024] The working principle of the utility model is as follows: the material receiving device is arranged on the side of the die-casting machine. When the die-casting machine opens the mold to unload the material, the linear driving rod 203 extends to push the sliding slot 202 to slide and extend from the fixed slot 201, and at the same time drives the material receiving basket 3 to move to the material receiving position. When just moving, the material receiving basket 3 moves forward relative to the push-pull frame 4, so that the half gear 301 pushes the rack 402 to push the push-pull frame 4 in the opposite direction of the extension of the sliding slot 202. At the same time, under the meshing drive of the half gear 301 and the rack 402, the material receiving basket 3 is rotated and vertically aligned, and the front end of the sliding long hole 401 is pressed on the sliding connecting column 208 and the push-pull frame 4 cannot continue to move relative to the sliding slot 202. At this time, the push-pull frame 4 and the material receiving basket 3 move synchronously with the sliding slot 202. When the material receiving basket 3 moves to the material receiving position, the hook 406 at the rear of the push-pull frame 4 is correspondingly hooked in the hook groove 206, and the sliding groove 202 is pressed on the front end of the sliding long hole 401 through the sliding connecting column 208, pushing the push-pull frame 4 forward, and the rear of the push-pull frame 4 is hooked in the hook groove 206 through the hook 406, thereby tightening and locking the push-pull frame 4, and through the meshing cooperation of the rack 402 and the half gear 301, the material receiving basket 3 is locked in a vertical state, so that the upper end opening of the material receiving basket 3 is opposite to the material dropping position, the die-casting falls off from the mold and falls into the material receiving basket 3, is blocked and buffered by the buffer surface composed of the buffer blocking head 6, and finally falls to the bottom plate of the material receiving basket 3, and is buffered by the upward blowing airflow of the nozzle 5 before contacting the bottom plate, further playing a buffering and deceleration role. After the die-casting machine falls onto the receiving basket 3, the linear drive rod 203 contracts and drives the sliding chute 202 and the receiving basket 3 to retract. When the action just begins, under the interaction of the half gear 301 and the rack 402, the push-pull frame 4 moves backward with the sliding chute 202, and the hook 406 is disengaged from the hook slot 206. At this time, the front end of the sliding long hole 401 is still pressed on the sliding connecting column 208, so that the push-pull frame 4 cannot move backward relative to the sliding chute 202, but can only move forward. Due to the meshing transmission effect of the half gear 301 and the rack 402, the receiving basket 3 can only tilt backward. It cannot tilt forward, thereby ensuring that the receiving basket 3 rotates and tilts toward the sliding slot 202. When the sliding slot 202 moves to the rear end, the second snap-in platform 404 will snap-in and press on the front end surface of the fixed slot 201, thereby pushing the push-pull frame 4 forward relative to the sliding slot 202, and further the rack 402 pushes the receiving basket 3 to rotate and tilt backward through the half gear 301, so that the die-casting in the receiving basket 3 slides out and falls into the telescopic slide 2, and slides onto the cooling conveyor belt 7, and is transported and transferred by the cooling conveyor belt 7, and cooled by blowing air through the fan 702.
