Description

Technical Field

[0001] The invention relates to the technical field of casting, in particular to a die-casting molding device and method with rapid cooling function. Background Art

[0002] Die casting is a kind of pressure-casting part. It 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 feed port 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. Burrs are generated during the stamping process. The shape of the stamping burrs varies depending on the material of the plate, the thickness of the plate, the gap between the upper and lower dies, the shape of the stamped parts, etc., and the burrs of die-castings are usually difficult to avoid, so the die-castings need to be deburred. Usually, after the die-casting is completed, the die-casting workpiece needs to be transported to a special surface treatment device for treatment, which increases the process of die-casting treatment and also increases the treatment time.

[0014] Before the die-casting process begins, the controller controls the push cylinders in the auxiliary body and the die-casting body to start, and then the push rod of the push cylinder pushes the moving rod to move. During the movement of the moving rod, the two pressing plates are respectively driven to move toward each other, and the two pressing plates move along the moving groove. Finally, the bottoms of the two pressing plates contact each other, and then the two pressing plates are combined into a die-casting cavity. At this time, the gap between the die-casting body and the pressing plate and the gap between the auxiliary body and the pressing plate are both connected to the processing chamber;

[0015] Then the cover plate is transported to the side close to the machine body, and the conveying nozzle is driven to move while the cover plate is transported, so that the conveying nozzle moves to the die-casting cavity formed by the two pressing plates, that is, the conveying nozzle extends into the die-casting cavity, so that the two pressing plates and the cover plate cooperate with each other to form a closed pressure vessel, and the height of the conveying nozzle in the die-casting cavity is adjusted to realize the die-casting of workpieces of different sizes, thereby improving the applicability of die-casting workpiece production;

[0016] Then the molten metal is transported to the die-casting cavity through the delivery nozzle. While the die-casting process is being carried out, the controller controls the hydraulic cylinder at the bottom of the processing chamber to start, and the push rod of the hydraulic cylinder drives the lifting plate to move, and the lifting plate then moves to the side close to the limiting body. When the lifting plate moves, it drives the rotating column and the fan blades to move, so that the fan blades extend into the delivery pipe. Then the controller controls the No. 3 motor to start, and the driving shaft of the No. 3 motor drives the rotating column to rotate. When the rotating column rotates, it drives several fan blades to rotate, and then the air in the processing chamber moves to the delivery pipe under the action of the fan blades, and moves through the delivery pipe to the gap between the die-casting body and the pressing plate and the gap between the auxiliary body and the pressing plate, so that there is air flow in the gap between the die-casting body and the pressing plate and the gap between the auxiliary body and the pressing plate. When the air flows, it contacts the surface of the pressing plate, and then takes away the heat generated by the die-casting, so that the die-casting workpiece is further cooled, thereby achieving the effect of rapid cooling;

[0017] After a period of cooling, the die-cast workpiece is formed, and the controller controls the push cylinders in the die-cast body and the auxiliary body to start, and the push rods of the push cylinders immediately drive the moving rods to contract, so that the moving rods respectively drive the two pressing plates to move to the opposite sides, and then the two pressing plates separate from each other, and the die-cast workpiece immediately moves from the die-casting cavity to the limiting groove;

[0018] When the die-cast workpiece moves to the processing chamber, one end of the die-cast workpiece contacts the placement plate, and the other end of the die-cast workpiece is located in the limiting groove. After the die-cast workpiece moves, the controller controls the two pressing plates to move toward each other again, so that the pressing plates are combined into a die-casting cavity again.

[0019] While the No. 3 motor drives the fan blades to rotate, the driving shaft of the No. 3 motor also drives the main gear to rotate. When the main gear rotates, it meshes with several driven gears, so that the driven gears also generate rotational force, and then the driven gear drives the placement plate to rotate, and the rotation of the placement plate drives the die-cast workpiece to rotate. While the die-cast workpiece rotates, the controller controls the No. 2 motor to start reciprocatingly, and the driving shaft of the No. 2 motor drives the moving wheel to rotate. When the moving wheel rotates, it frictionally contacts with the vertical groove, so that the moving wheel reciprocates along the vertical groove, and then the sliding block reciprocates under the action of the moving wheel. While the sliding block moves, The controller controls the micro motor to drive the grinding roller to rotate, so that the grinding roller contacts the surface of the die-cast workpiece when rotating, and the rotation direction of the grinding roller is opposite to that of the die-cast workpiece, so that the fan blades convey the air while the placement plate drives the die-cast workpiece to rotate and contact with the grinding roller, thereby achieving the effect of air flow and workpiece grinding, thereby saving the subsequent process of die-casting, and when the fan blades rotate, the air moves the debris generated by grinding, which not only realizes the cooling of the pressing plate, but also conveys the debris generated by grinding to the impurity removal chamber through the flow channel, so that the debris is accumulated and stored in the impurity removal chamber;

[0020] After a period of grinding, the controller controls motor No. 1 to start, and the drive shaft of motor No. 1 drives the transmission wheel to rotate. The transmission wheel moves along the slide groove, so that the limit body rotates under the action of the support frame, so that the limit groove faces one side of the output plate. Finally, the output plate is separated from the machine body, so that the outside world is connected to the processing chamber, and the staff then takes the polished workpiece out of the processing chamber.

[0022] The molding method comprises the following specific steps:

[0023] S1, combining two pressing plates into a die-casting cavity;

[0024] S2, die-casting the workpiece in the die-casting cavity;

[0025] S3, the die-cast workpiece moves to the processing chamber;

[0026] S4, the die-cast workpiece is polished by the polishing roller in the limiting groove;

[0027] S5. The polished die-casting workpiece is output.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] By setting the die-casting chamber and the processing chamber, the die-casting and grinding of the workpiece can be carried out at the same time, thereby saving the processing steps of the die-casting workpiece and the processing time of the die-casting workpiece, thereby improving the processing efficiency of the die-casting workpiece, and when the No. 3 motor drives the main gear to rotate, the main gear not only drives the rotating column to rotate, thereby driving the fan blades to rotate, so that the air in the processing chamber flows to the die-casting chamber through the conveying pipe, and then the flowing air contacts the pressing plate, thereby taking away the heat generated by the die-casting, thereby achieving the effect of rapid cooling; at the same time, the rotation of the main gear also drives the driven gear to rotate, and the driven gear drives the die-casting workpiece to rotate through the placement plate, so that the die-casting workpiece is in a vertical state between the limit groove and the placement plate under the action of the limit groove and the grinding roller, and the opposite rotation directions of the grinding roller and the placement plate are used to grind the surface of the die-casting workpiece, thereby improving the surface cleanliness of the die-casting workpiece.

[0053] A molding method of a die-casting molding device with a rapid cooling function,

[0054] The molding method comprises the following specific steps:

[0055] S1, combining two pressing plates 24 into a die-casting cavity;

[0056] S2, die-casting the workpiece in the die-casting cavity;

[0057] S3, the die-cast workpiece moves to the processing chamber 12;

[0058] S4, the die-cast workpiece is polished by the polishing roller 34 in the limiting groove 32;

[0059] S5. The polished die-casting workpiece is output.

[0060] Working principle of the present invention:

[0061] Before the die-casting process begins, the controller controls the push cylinders in the auxiliary body 22 and the die-casting body 21 to start, and then the push rod of the push cylinder pushes the moving rod to move. During the movement of the moving rod, the two pressing plates 24 are respectively driven to move toward each other, and the two pressing plates 24 move along the moving groove 23. Finally, the bottoms of the two pressing plates 24 contact each other, and then the two pressing plates 24 are combined into a die-casting cavity. At this time, the gap between the die-casting body 21 and the pressing plate 24 and the gap between the auxiliary body 22 and the pressing plate 24 are both connected to the processing chamber 12;

[0062] Then, the cover plate 13 is conveyed to the side close to the machine body 1, and the conveying nozzle is driven to move while the cover plate 13 is conveyed, so that the conveying nozzle moves to the die-casting cavity formed by the two pressing plates 24, that is, the conveying nozzle extends into the die-casting cavity, so that the two pressing plates 24 and the cover plate 13 cooperate with each other to form a closed pressure vessel, and the height of the conveying nozzle in the die-casting cavity is adjusted to realize the die-casting of workpieces of different sizes, thereby improving the applicability of die-casting workpiece production;

[0063] Then the molten metal is delivered to the die casting chamber through the delivery nozzle. While the die casting process is being carried out, the controller controls the hydraulic cylinder at the bottom of the processing chamber 12 to start, and the push rod of the hydraulic cylinder drives the lifting plate 35 to move, and the lifting plate 35 then moves to the side close to the limit body 31. When the lifting plate 35 moves, it drives the rotating column and the fan blades 37 to move, so that the fan blades 37 extend into the delivery pipe 311. Then the controller controls the No. 3 motor to start, and the driving shaft of the No. 3 motor drives the rotating column to rotate. When the rotating column rotates, it drives a plurality of fan blades 37 to rotate, and then The air in the processing chamber 12 moves toward the delivery pipe 311 under the action of the fan blades 37, and moves to the gap between the die-cast body 21 and the pressing plate 24 and the gap between the auxiliary body 22 and the pressing plate 24 through the delivery pipe 311, so that air flows in the gap between the die-cast body 21 and the pressing plate 24 and the gap between the auxiliary body 22 and the pressing plate 24. When the air flows, it contacts the surface of the pressing plate 24, and then takes away the heat generated by the die-casting, so that the die-casting workpiece is further cooled, thereby achieving a rapid cooling effect;

[0064] After a period of cooling, the die-cast workpiece is formed, and the controller controls the push cylinders in the die-cast body 21 and the auxiliary body 22 to start, and the push rods of the push cylinders then drive the moving rods to contract, so that the moving rods respectively drive the two pressing plates 24 to move to the opposite sides, and then the two pressing plates 24 separate from each other, and the die-cast workpiece then moves from the die-casting cavity to the limiting groove 32;

[0065] When the die-cast workpiece moves to the processing chamber 12, one end of the die-cast workpiece contacts the placement plate, and the other end of the die-cast workpiece is located in the limiting groove 32. After the die-cast workpiece moves, the controller controls the two pressing plates 24 to move toward each other again, so that the pressing plates 24 are combined into a die-casting cavity again.

[0066] While the No. 3 motor drives the fan blades 37 to rotate, the driving shaft of the No. 3 motor also drives the main gear 36 to rotate. When the main gear 36 rotates, it meshes with a number of driven gears 38, so that the driven gears 38 also generate a rotational force, and then the driven gears 38 drive the placement plate to rotate, and when the placement plate rotates, it drives the die-cast workpiece to rotate. While the die-cast workpiece rotates, the controller controls the No. 2 motor to start reciprocatingly, and the driving shaft of the No. 2 motor drives the moving wheel to rotate. When the moving wheel rotates, it frictionally contacts the vertical groove 16, so that the moving wheel reciprocates along the vertical groove 16, and then the sliding block 33 reciprocates under the action of the moving wheel. While the sliding block 33 moves , the controller controls the micro motor to drive the grinding roller 34 to rotate, so that the grinding roller 34 contacts the surface of the die-casting workpiece when rotating, and the rotation direction of the grinding roller 34 is opposite to the rotation direction of the die-casting workpiece, so that the fan blade 37 conveys the air while the placement plate drives the die-casting workpiece to rotate and contact with the grinding roller 34, thereby achieving the effect of air flow and workpiece grinding, thereby saving the subsequent process of die-casting, and when the fan blade 37 rotates, the air moves with the debris generated by grinding, which not only realizes the cooling of the pressing plate 24, but also transports the debris generated by grinding to the impurity removal chamber 25 through the flow channel, so that the debris is accumulated and stored in the impurity removal chamber 25;

[0067] After a period of grinding, the controller controls motor No. 1 to start, and the driving shaft of motor No. 1 drives the transmission wheel to rotate. The transmission wheel moves along the slide groove 15, so that the limit body 31 rotates under the action of the support frame, so that the limit groove 32 faces one side of the output plate 14. Finally, the output plate 14 is separated from the machine body 1, so that the outside world is connected with the processing chamber 12, and the staff then takes the polished workpiece out of the processing chamber 12.

[0068] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
