Description

Technical Field

[0001] The present application relates to the technical field of molding machines, and in particular to a molding machine and a control method thereof. Background Art

[0002] A molding machine is a device used in industrial production to process materials into a specific shape. Its working principle usually involves heating the material to a certain temperature to make it soft or molten, then injecting or pressing it into a mold under pressure, and forming the desired shape after cooling.

[0003] The existing molding machine is connected to many pipes, and it is impossible to use a mechanical arm to clamp the molded product. The temperature of the molded product is high, and it is necessary to wait for the product to cool down before taking the product manually. Although the existing molding machine has a cooling structure, the temperature of the entire mold is still relatively high, and it is still necessary to wait for a period of time before taking the product. At this time, the equipment cannot continue to work, resulting in low overall production efficiency of the product, which needs to be improved. Summary of the invention

[0004] The purpose of this application is to provide a molding machine and a control method in order to improve the overall production efficiency of the product.

[0005] A molding machine and a control method provided in the present application adopt the following technical scheme: comprising a clamping frame, wherein the clamping frame is connected to a feed barrel, rotatably connected to a fixed mold and slidably connected to a movable mold, the fixed mold and the movable mold are both connected to a compressed air pipe, a steam pipe and a cooling water pipe, the movable mold and the fixed mold are both connected to the feed barrel, the clamping frame is connected to a first driving member for driving the movable mold to slide toward or away from the fixed mold, the fixed mold is connected to a locking mechanism for locking the fixed mold and the movable mold, and the clamping frame is connected to a driving component for driving the fixed mold to rotate.

[0006] By adopting the above technical solution, the compressed air in the compressed air pipe enters the fixed mold and the movable mold to air-cool the fixed mold and the movable mold; the cooling water in the cooling water pipe enters the fixed mold and the movable mold to water-cool the fixed mold and the movable mold, and the fixed mold and the movable mold are initially cooled. The first driving member drives the movable mold to slide in the direction away from the fixed mold, so that the movable mold is separated from the fixed mold, and the driving component drives the fixed mold to rotate. The molded product rotates with the rotation of the fixed mold, so that the side of the fixed mold equipped with the product is separated from the movable mold, and the other side corresponds to the movable mold. The side of the fixed mold without the product can continue to cooperate with the movable mold and mold the product, which saves the time of waiting for the product to cool down and improves the overall production efficiency of the product.

[0007] Optionally, the locking mechanism includes a locking column slidably connected to the movable mold, a second driving member connected to the movable mold, and a locking assembly connected to the fixed mold, the second driving member is used to drive the locking column to slide toward or away from the fixed mold, the locking assembly is used to fix or release the locking column, and the locking assembly is connected to both opposite sides of the fixed mold.

[0008] By adopting the above technical solution, the second driving member drives the locking column to move toward the fixed mold until the locking column moves to the locking assembly, and the locking assembly fixes the locking column on the fixed mold. Foam particles are filled between the mobile mold and the fixed mold, and then high-temperature steam is filled between the mobile mold and the fixed mold. The pressure between the mobile mold and the fixed mold is relatively large, and the mobile mold and the fixed mold have a force to move away from each other. The second driving member drives the end of the locking column away from the mobile mold to move toward the fixed mold, so that the mobile mold and the fixed mold have a force to move toward each other. The fixed mold is subjected to two forces in opposite directions, thereby reducing the force on the rotating part of the fixed mold, and protecting the rotating part of the fixed mold.

[0009] Optionally, the locking assembly includes a locking plate slidably connected to the side of the fixed mold away from the movable mold and a third driving member for driving the locking plate to slide, the third driving member is connected to the fixed mold, the locking column is provided with an annular groove, the locking column is formed with a convex column, the radius of the convex column is smaller than the radius of the locking column, the locking plate is provided with a through hole for the locking column to pass through and a locking hole for cooperating with the convex column, the through hole is connected to the locking hole, and the radius of the locking hole is smaller than the radius of the through hole.

[0010] By adopting the above technical solution, when the locking assembly is required to fix the locking column on the fixed mold, one end of the locking column passes through the fixed mold and the through hole, and the convex column at this time corresponds to the locking hole, and the locking plate is moved so that the convex column is stuck in the locking hole. The movable mold is pressurized so that the locking column has a force to move toward the fixed mold, the locking column abuts against the locking plate, the locking plate abuts against the fixed mold, the locking column applies force to the locking plate, the locking plate applies force to the fixed mold, and the locking plate and the fixed mold limit the movement of the locking column. When high-temperature steam is filled between the movable mold and the fixed mold, the stability of the movable mold is improved compared to the fixed mold.

[0011] Optionally, a direct abutment ring and an indirect abutment ring are sleeved on one side of the boss away from the locking column, the direct abutment ring is located between the indirect abutment ring and the boss, the direct abutment ring and the indirect abutment ring abut, the locking column is provided with a receiving groove for the indirect abutment ring to be snapped in, the locking column is threadedly connected with a stop block, and the stop block is provided with a stop groove for the indirect abutment ring to be snapped in.

[0012] By adopting the above technical solution, when the direct abutment ring is subjected to force, the direct abutment ring applies force to the indirect abutment ring, and the indirect abutment ring is subjected to force and applies force to the inner wall of the accommodating groove, thereby reducing the force on the stop block and protecting the internal thread of the stop block and the external thread of the third boss.

[0013] Optionally, the positioning assembly includes a connecting rod slidably connected to the mold clamping frame and a fourth driving member for driving the connecting rod to slide toward or away from the movable mold, the fourth driving member is connected to the mold clamping frame, the output end of the fourth driving member is threadedly connected with a zero-point positioning block, the connecting rod is threadedly connected to the output end of the fourth driving member, the zero-point positioning block is located between the fourth driving member and the connecting rod, and the connecting rod is threadedly connected with a rotating sleeve.

[0014] By adopting the above technical solution, before the first production, it is necessary to perform the zero-position alignment operation. First, fit the mobile mold and the fixed mold together, and rotate the rotating sleeve shell so that the rotating sleeve shell is located at the end of the connecting rod closest to the zero-point positioning block. The fourth driving member drives the output end of the fourth driving member to extend, and the output end of the fourth driving member moves the maximum stroke, and the connecting rod is rotated so that the side of the rotating sleeve shell away from the zero-point positioning block abuts against the mobile mold. At this time, the zero-point positioning block is rotated in the direction close to the rotating sleeve shell, so that the zero-point positioning block abuts against the connecting rod, and the zero-point alignment is completed. When the distance between the mobile mold and the fixed mold needs to be adjusted, the rotating sleeve shell is rotated in the direction away from the zero-point positioning block until the rotating sleeve shell moves to the corresponding position, and the moving distance of the rotating sleeve shell is the spacing between the mobile mold and the fixed mold. When the mobile mold moves in the direction close to the fixed mold, the mobile mold abuts against the rotating sleeve shell, and the rotating sleeve shell limits the movement of the mobile mold, so as to better control the spacing between the mobile mold and the fixed mold.

[0015] Optionally, one end of the connecting rod away from the fourth driving member is detachably connected to a fixing block, the rotating sleeve is located between the zero point positioning block and the fixing block, and the fixing block is used to abut against the rotating sleeve.

[0016] By adopting the above technical solution, when the position of the rotating shell is moved, the fixed block is installed on the connecting rod. The fixed block limits the movement of the rotating shell toward the fixed block, thereby improving the stability of the rotating shell installed on the connecting rod.

[0017] Optionally, the feed barrel includes a barrel connected to the clamping frame, a feed pipe connected to the top of the barrel and a feed pipe connected to the bottom of the barrel, the fixed mold and the movable mold are both connected to the feed pipe, a dividing plate is connected to the barrel, the dividing plate is provided with dividing holes, a control plate for covering the dividing holes is rotatably connected to the barrel, a rotating assembly for driving the control plate to rotate is connected to the barrel, and the control plate is located between the dividing plate and the feed port of the feed pipe.

[0018] By adopting the above technical solution, the foam plastic enters the cylinder through the feeding pipe and falls on the dividing plate, and part of the foam plastic falls into the dividing hole. When it is necessary to feed into the feeding pipe, the rotating assembly drives the control plate to rotate so that the control plate and the dividing hole are staggered, and the foam plastic in the dividing hole and the foam plastic on the dividing plate pass through the dividing hole and enter the feeding pipe. When the foam plastic in the feeding pipe reaches a corresponding amount, the rotating assembly drives the control plate to rotate so that the control plate covers the dividing hole, thereby limiting the foam plastic from passing through the dividing hole. By controlling the amount of foam plastic in the feeding pipe, the occurrence of feed pipe blockage is reduced.

[0019] Optionally, the rotating assembly includes a rotating column rotatably connected to the cylinder body and a rotating structure for driving the rotating column to rotate, the rotating structure is connected to the cylinder body, the control plate is connected to the rotating column, the rotating column passes through the dividing plate, one end of the rotating column is connected to a plurality of stirring plates, and the dividing plate is located between the stirring plate and the control plate.

[0020] By adopting the above technical solution, the rotating structure drives the rotating column to rotate, so that the control plate is staggered with the material distribution hole or the control plate covers the material distribution hole, which is convenient for controlling the amount of foam plastic entering the feeding pipe. The stirring plate rotates with the rotation of the rotating column, and the rotation of the stirring plate is connected through the rotating column, the connecting rod and the rotating structure, which reduces the drive and increases the relevance of the overall structure.

[0021] Optionally, a reflux box is connected between the cylinder and the feed pipe, the reflux box is connected to the cylinder through a connecting pipe, one end of the feed pipe is connected to the reflux box, the reflux box is connected to the conveying pipe through a reflux pipe, and the reflux pipe is connected to a reflux pump.

[0022] By adopting the above technical solution, when there is too much foam plastic in the reflux box, the reflux pump sucks the foam plastic in the reflux box back to the feed pipe through the reflux pipe, preventing excessive foam plastic from entering the feed pipe and reducing the occurrence of feed pipe blockage.

[0023] Optionally, a control method,

[0024] Step A, zero-position alignment: first fit the movable mold and the fixed mold together, rotate the rotating shell so that the rotating shell is located at the end of the connecting rod closest to the zero-point positioning block, rotate the fixed block so that the fixed block abuts against the rotating shell, the fourth driving member drives the output end of the fourth driving member to extend, the output end of the fourth driving member moves to the maximum stroke, rotate the connecting rod so that the side of the fixed block away from the rotating shell abuts against the movable mold, and at this time rotate the zero-point positioning block in the direction close to the rotating shell so that the zero-point positioning block abuts against the connecting rod, completing the zero-point alignment;

[0025] Step B, adjusting the distance between the movable mold and the fixed mold: first loosen the fixed block so that the fixed block is separated from the rotating shell, then rotate the rotating shell, and know the moving distance of the rotating shell according to the first scale line and the second scale line. When the rotating shell moves to the corresponding position, rotate the fixed block in the direction close to the rotating shell so that the fixed block abuts against the rotating shell. The moving distance of the rotating shell is the distance between the movable mold and the fixed mold;

[0026] Step C, mold closing: the first driving member drives the movable mold to slide in a direction close to the fixed mold until the movable mold abuts against the fixed block;

[0027] Step D, locking: the second driving member drives the locking column to slide in a direction close to the fixed mold, and one end of the locking column passes through the fixed mold and the through hole until the protruding column corresponds to the locking hole, and the third driving member drives the locking plate to move so that the protruding column is stuck in the locking hole, thereby locking the fixed mold and the movable mold;

[0028] Step E, feeding: the foam plastic in the feeding cylinder enters the fixed mold and the movable mold respectively through the feeding pipe;

[0029] Step F, steam charging: high-temperature steam is charged into the fixed mold and the movable mold through the steam pipe, and the second driving member drives the end of the locking column away from the movable mold to slide toward the fixed mold, and the fixed mold and the movable mold discharge steam;

[0030] Step G, cooling: cooling water enters the movable mold and the fixed mold through the cooling water pipe for water cooling; compressed air enters the movable mold and the fixed mold through the compressed air pipe for air cooling.

[0032] Step I, flipping the fixed mold: the driving assembly drives the fixed mold to rotate so that the other side of the fixed mold corresponds to the movable mold.

[0033] By adopting the above technical solution, the first driving member drives the movable mold to slide in the direction away from the fixed mold, so that the movable mold is separated from the fixed mold, and the driving component drives the fixed mold to rotate. The molded product rotates with the rotation of the fixed mold, so that the side of the fixed mold with the product is away from the movable mold, and the other side corresponds to the movable mold.
