DETAILED DESCRIPTION

[0023] The following will be described in detail below Figures 1-5 The application will be further described in detail.

[0024] The application discloses an optical injection molding piece hot cutting machine.

[0025] Reference Figure 1 An optical injection molding piece hot cutting machine comprises a rack 1 with an operation platform 11 inside, a hot cutting frame 2 slidingly arranged on the operation platform 11, and a movable frame 3 slidingly arranged on the operation platform 11 along the axis of the hot cutting frame 2, and the hot cutting frame 2 and the movable frame 3 are coaxial. A tray 31 is detachably installed on the movable frame 3 and used for containing injection molding pieces after hot cutting. A discharging manipulator 4 is slidingly arranged on the operation platform 11 at an end away from the hot cutting frame 2 and used for clamping and placing the hot-cut injection molding pieces into the tray 31. A conveying assembly 5 is arranged on the operation platform 11 and used for conveying the injection molding pieces to be processed to a cutting station. A hot cutting mechanism 6 for hot cutting the injection molding pieces is arranged on the operation platform 11 at a position away from the movable frame 3, and the hot cutting mechanism 6 coincides with the hot cutting machine in the vertical direction when the injection molding pieces are hot cut.

[0026] Reference Figure 2Specifically, the hot cutting mechanism 6 comprises a cutting platform 61 fixedly installed on the hot cutting frame 2, four vertical rods 62 fixedly arranged on the operation platform 11, a hot cutting driving member 63 fixedly installed on the ends of the four vertical rods 62 away from the operation platform 11, and a movable plate 64 slidingly arranged on the four vertical rods 62. The four vertical rods 62 are arranged in a quadrilateral array at the end of the hot cutting frame 2 away from the movable frame 3 in the sliding direction, and serve as supports. The telescopic end of the hot cutting driving member 63 is fixedly connected with the movable plate 64, so as to drive the movable plate 64 to slide along the vertical rods 62. The hot cutting head 641 is installed on the side of the movable plate 64 close to the operation platform 11. The cutting platform 61 is provided with a waste hole 611 penetrating through the middle portion and used for allowing the cutting waste to pass through. The hot cutting head 641 is matched in size with the waste hole 611.

[0027] When the injection molded part is hot cut, the injection molded part is placed on the cutting platform 61. At this time, the hot cutting head 641 cuts the injection molded part along the middle portion under the action of the hot cutting driving member 63, so that two effective injection molded parts are separated from the connecting injection molded part in the middle portion. Then, the two effective injection molded parts are respectively left on the cutting platform 61 on both sides of the waste hole 611, and the connecting injection molded part is discharged through the waste hole 611.

[0028] It is worth mentioning that the recycling hole 111 is penetratingly arranged on the operation platform 11. When the hot cutting frame 2 is located at the cutting position, the waste hole 611 coincides with the recycling hole 111, so as to facilitate the recycling of the waste.

[0029] It should be noted that the hot cutting driving member 63 in the present application serves to drive the movable plate 64 to slide along the vertical rods 62. Any driving member capable of achieving this action, such as a pneumatic cylinder, a telescopic rod, an oil cylinder, etc., shall be included in the protection scope of the present application.

[0030] With reference to Figure 2 The side of the movable plate 64 close to the hot cutting driving member 63 is fixedly installed with four rubber sleeves 642, and the four rubber sleeves 642 are respectively slidingly connected with the four vertical rods 62, so as to serve as a protection function and prevent the movable plate 64 from colliding with the hot cutting driving member 63.

[0031] With reference to Figure 3 The hot cutting head 641 is provided with a cutting groove 6411 penetratingly arranged along the length direction, and the cutting groove 6411 is in communication with the side of the hot cutting head 641 away from the movable plate 64. The injection molded part to be hot cut comprises a connecting short rod and a blank symmetrically arranged on both sides of the injection molded part. When the injection molded part is hot cut, the connecting short rod will temporarily enter the cutting groove 6411, and will not be scattered, so as to improve the safety of the overall operation of the mechanism.

[0032] It should be noted that the blank and the connecting short rod formed in the injection molding part described in the embodiment are not only one injection molding part, but also a kind of injection molding parts with similar structure. The description of the injection molding part is not a limitation of the application scope.

[0033] With reference to Figure 4 Specifically, the conveying assembly 5 includes a transverse cylinder 51 vertically installed at the end of the hot cutting frame 2 away from the movable frame 3, and a longitudinal push rod 52 installed at the end of the transverse cylinder 51 close to the hot cutting frame 2. An upper loading manipulator 53 is arranged at the end of the transverse cylinder 51 away from the longitudinal cylinder 55 on the operation platform 11, which functions to receive the injection molding part and place it on the moving station of the transverse cylinder 51. The longitudinal push rod 52 is connected with a material clamping driving part 54 and a longitudinal cylinder 55 for driving the longitudinal push rod 52 at both ends. When the transverse cylinder 51 moves the injection molding part to the axis position of the hot cutting frame 2, the material clamping driving part 54 clamps the injection molding part and places it on the cutting platform 61 under the driving of the longitudinal cylinder 55.

[0034] Further, the material clamping driving part 54 specifically includes two movable clamping rods 541 symmetrically and slidingly connected with one end of the longitudinal push rod 52, and the two movable clamping rods 541 are commonly connected with a clamping cylinder 542 for driving the two movable clamping rods 541 to move closer to or farther away from each other. In addition, the centers of the two movable clamping rods 541 are located on the axis of the hot cutting frame 2, so that the two clamping rods can place the injection molding part on the cutting platform 61 at the central position perpendicular to the sliding direction.

[0035] With reference to Figure 4 Further, the transverse cylinder 51 is a slide cylinder, which has a faster response speed and can more conveniently carry the injection molding part. The moving station of the transverse cylinder 51 is provided with a rotating seat 511 for rotating the injection molding part, so that the two movable clamping rods 541 can smoothly clamp the injection molding part without colliding with the injection molding part.

[0036] With reference to Figure 5 Specifically, the unloading manipulator 4 includes slide rails 41 symmetrically and slidingly arranged at both ends of the operation platform 11 along the length direction of the operation platform 11, a driving cylinder 42, and a vertical plate 43. The lower two ends of the vertical plate 43 are symmetrically provided with two slide seats 431, and the two slide seats 431 are slidingly connected with the slide rails 41 and drivingly connected with the cylinder, respectively. A unloading clamping jaw 44 is slidingly arranged on the vertical plate 43 along the length direction, which functions to clamp the injection molding part and put the injection molding part into the tray 31.

[0037] The implementation principle of the optical injection molding part hot cutting machine according to the embodiment of the application is as follows:

[0038] After the injection molding piece is placed on the moving station of the horizontal air cylinder 51 by the feeding mechanical arm 53, the horizontal air cylinder 51 moves and drives the injection molding piece to move through the rotating seat 511 thereon. Then the two movable clamping rods 541 on the vertical push rod 52 are clamped to the injection molding piece under the drive of the clamping air cylinder 542, and the injection molding piece is placed on the cutting platform 61 through the pushing of the vertical air cylinder 55.

[0039] At this time, the movable plate 64 cuts the injection molding piece under the power of the hot cutting driving member 63, and the remaining two injection molding pieces are clamped and placed into the tray 31 by the discharging mechanical arm 4, so as to realize the integrated hot cutting and tray loading operation of the injection molding piece, greatly improve the hot cutting efficiency and reduce the labor consumption.

[0040] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, so: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
