[0002] Mold processing refers to the process of manufacturing various types of molds, which are used to produce a large number of products of the same shape. Molds play an important role in the manufacturing industry and can be used in the production of plastic products, metal parts, glass products, etc. In the process of mold processing, sometimes it is necessary to use a stamping molding device to process the mold into a specific shape;

[0003] A stamping device is a common metal processing equipment, which is used to apply high pressure force to metal sheets or strips through a die to cause plastic deformation, thereby forming parts or products of desired shapes. Stamping devices are widely used in automobile manufacturing, electronic products, home appliances, aerospace and other industries. Common die stamping devices are usually composed of an upper die assembly and a lower die assembly, and may also include modules of multiple steps to achieve complex forming processes. The existing stamping devices are found to have the following problems in the prior art during use:

[0004] 1. After stamping, the mold cannot be automatically demolded and discharged. The mold is generally embedded in the lower mold assembly and fits together with the inner wall of the lower mold assembly. When demolding, the staff needs to reach into the lower mold assembly to pull out the mold;

[0005] 2. After each stamping is completed, when the staff takes the mold, if a mold fits tightly with the lower mold assembly, the removal process will take a long time, and the upper mold assembly on the top may press down at any time and injure the staff's hands, which poses a certain risk. Utility Model Content

[0006] The purpose of the utility model is to provide a stamping and forming device that is easy to demould, so as to solve the problems mentioned in the above background technology that ordinary stamping and forming cannot be automatically demoulded and discharged after stamping is completed, and there are certain risks in the discharge process of manual discharge. In order to achieve the above purpose, the utility model provides the following technical solutions: a stamping and forming device that is easy to demould, including a base, a lifting cylinder is installed on the top of the base, an upper die seat is provided at one end of the lifting cylinder, a lower die seat is provided below the upper die seat, a discharge mechanism is installed on one side of the lower die seat, and a demoulding mechanism is installed inside the lower die seat.

[0007] The discharging mechanism comprises a discharging tray, the surface of which is rotatably connected with a shifting rod, one end of which is mounted with an output shaft of a first motor, and a receiving tray is inserted into the lower surface of the discharging tray.

[0008] The demoulding mechanism includes a base plate, the bottom of the base plate is slidably connected to a rotating rod, the front of the rotating rod is welded with a rotating shaft, one end of the rotating shaft is installed with a small gear, the bottom of the small gear is meshed with a large gear, and the inner wall of the large gear is installed with the output shaft of the second motor.

[0009] Further preferably, the lever is rotated by a first motor.

[0010] Further preferably, the front side of the receiving tray is configured as an open structure.

[0011] Further preferably, the large gear is an incomplete gear that is partially toothless, and the large gear is rotated by a second motor.

[0012] Further preferably, a meshing transmission structure is provided between the large gear and the small gear.

[0013] Further preferably, a sliding connection is adopted between the base plate and the lower die base, and the base plate is configured to perform linear reciprocating motion via a second motor.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the utility model, a demoulding mechanism is added inside the lower die seat, so that the stamped mold can be quickly pushed out of the lower die seat after the stamping is completed. The bottom plate can reciprocate up and down along the lower die seat, and the rotation of the pinion can drive the rotation of the rotating shaft. During stamping, the bottom plate is located inside the lower die seat. After the stamping is completed, the bottom plate is driven by the second motor to slide to the top along the lower die seat, so that it is separated from the lower die seat, and the material is discharged faster.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a stamping forming device that is easy to demould, including a base 1, a lifting cylinder 2 is installed on the top of the base 1, an upper die seat 3 is provided at one end of the lifting cylinder 2, a lower die seat 4 is provided below the upper die seat 3, a discharge mechanism 5 is installed on one side of the lower die seat 4, and a demoulding mechanism 6 is installed inside the lower die seat 4.

[0024] The discharging mechanism 5 comprises a discharging tray 501 , the surface of which is rotatably connected to a lever 502 , one end of which is mounted with an output shaft of a first motor 503 , and a receiving tray 504 is plugged into the lower surface of the discharging tray 501 .

[0025] The demoulding mechanism 6 includes a base plate 601, the bottom of the base plate 601 is slidably connected to a rotating rod 602, the front of the rotating rod 602 is welded with a rotating shaft 603, one end of the rotating shaft 603 is installed with a small gear 604, the bottom of the small gear 604 is meshed with a large gear 605, and the inner wall of the large gear 605 is installed with the output shaft of the second motor 606.

[0026] In this embodiment, Figure 1 and Figure 2 As shown, the lever 502 is rotated by the first motor 503; it should be noted that the lever 502 is rotated clockwise at a constant speed by the first motor 503. When the lever 502 rotates to the surface of the lower mold base 4, it can drive the mold on the surface of the bottom plate 601 to separate from the bottom plate 601 and move together with the lever 502.

[0027] In this embodiment, Figure 1As shown, the front of the receiving tray 504 is set as an open structure; it should be noted that when the lever 502 moves the mold to the top of the receiving tray 504, it automatically falls into the receiving tray 504, and the staff can take the mold out from the opening on the front of the receiving tray 504 without having to put their hands under the lower mold base 4, which is safer.

[0028] In this embodiment, Figure 3 As shown, the large gear 605 adopts an incomplete gear without some teeth, and the large gear 605 rotates through the second motor 606; it should be noted that the large gear 605 can be driven to rotate by the second motor 606, and the small gear 604 can be driven to rotate intermittently by the incomplete gear without some teeth.

[0029] In this embodiment, Figure 3 As shown, a meshing transmission structure is set between the large gear 605 and the small gear 604; it should be noted that when the toothed side of the large gear 605 meshes with the small gear 604, the large gear 605 rotates continuously, which can drive the small gear 604 to rotate, and the rotation of the small gear 604 can drive the rotating shaft 603 to rotate. The meshing transmission of the large gear 605 and the small gear 604 has higher transmission efficiency, increases the service life of the equipment, and is more stable.

[0030] In this embodiment, Figure 3 and Figure 4 As shown, a sliding connection is adopted between the bottom plate 601 and the lower die base 4, and the bottom plate 601 performs a linear reciprocating motion through the second motor 606; it should be noted that under the drive of the second motor 606, the bottom plate 601 performs an up and down reciprocating motion along the lower die base 4, and the sliding of the bottom plate 601 is limited by the lower die base 4, and is always located in the same vertical line during the movement. A slideway is provided on the inner wall of the lower die base 4, and when the bottom plate 601 slides to the bottom, it fits with the bottom of the slideway to support the bottom plate 601, and prevents the bottom plate 601 from continuing to slide down when the upper die base 3 is stamped.

[0031] The use method and advantages of the utility model: When the stamping forming device which is easy to demould is used, the working process is as follows:

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first start the second motor 606, and the second motor 606 drives the large gear 605 to rotate. When the toothed side of the large gear 605 fits with the small gear 604, the small gear 604 is turned to rotate 180°, driving the rotating shaft 603 and the rotating rod 602 to rotate 180°. The rotating shaft 603 and the lower die seat 4 are supported by connecting rods and bearings. When the rotating rod 602 rotates 180°, the bottom plate 601 slides from the top to the bottom along the lower die seat 4. At this time, the toothless side of the large gear 605 fits with the small gear 604, and the small gear 604 stops rotating. The mold to be stamped is placed above the bottom plate 601 in the remaining gap, and the lifting cylinder 2 is started to drive the lower die seat 4 to press down. After stamping, the large gear 605 rotates back once, and the toothed side of the large gear 605 meshes with the small gear 604 again, and the small gear 604 is turned to rotate 180° again, further driving the bottom plate 601 to slide to a position flush with the upper surface of the lower die base 4. At this time, the lever 502 on one side just rotates back once, and the mold on the surface of the bottom plate 601 is turned into the receiving tray 504 on one side. The first motor 503 and the second motor 606 both use servo motors, which can adjust the speed of the first motor 503 and the second motor 606. At the same time, the movement gap of the lifting cylinder 2 is adjusted, and the movement rhythm of each mechanism is adjusted to achieve automatic discharge after each stamping is completed.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
