[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] This utility model provides two technical solutions:

[0026] Figure 1-Figure 5 The first embodiment is shown: a lunch box production trimming mold, comprising a base plate 1, a motorized slide 2 is provided at the top of the base plate 1, the motorized slide 2 is a prior art, and can drive a lower die base 3 to move on the base plate 1, the output end of the motorized slide 2 is fixedly connected to the lower die base 3, a group of concave dies 4 is provided at the top of the lower die base 3, a trimming assembly 5 is provided at the top of the base plate 1 for trimming the lunch box, and a limiting assembly 6 is provided at the top of the base plate 1 for limiting the position of the lunch box;

[0027] The trimming assembly 5 includes a mounting frame 51, an electric push rod 52 is fixedly mounted on the top of the inner wall of the mounting frame 51, an upper die base 54 is fixedly mounted on the output end of the electric push rod 52, and a group of punches 55 are fixedly mounted on the bottom end of the upper die base 54. The electric push rod 52 is a prior art and can drive the upper die base 54 and the punches 55 to move, so as to facilitate trimming of the plastic lunch box below. A protective frame 56 is fixedly mounted on the bottom end of the upper die base 54;

[0028] The limiting assembly 6 includes a bracket 61 , which is fixedly connected to the base plate 1 , and two rotating rods 63 are rotatably mounted between opposite sides of the bracket 61 .

[0029] The mounting frame 51 is fixedly connected to the base plate 1, and four sliding rods 53 are fixedly installed on the top of the upper mold base 54. The top ends of the four sliding rods 53 slide through the top end of the mounting frame 51, and the sliding rods 53 play a guiding role in the movement of the upper mold base 54, so that the upper mold base 54 moves more smoothly. A flexible protective cover 57 is fixedly installed on the bottom end of the protective frame 56. The bottom end horizontal plane of the flexible protective cover 57 is lower than the bottom end horizontal plane of the punch 55. When the flexible protective cover 57 descends, it will first contact the lower mold base 3, so that the flexible protective cover 57 can fit tightly with the lower mold base 3, and the flexible protective cover 57 has a certain flexibility, so it will not hinder the punch 55 from contacting the plastic lunch box. The bottom end horizontal plane of the protective frame 56 is higher than the bottom end horizontal plane of the punch 55. When the protective frame 56 and the punch 55 move downward together, the punch 55 will contact the plastic lunch box below, while the protective frame 56 will not contact it, so that the protective frame 56 and the flexible protective cover 57 can prevent plastic particles from splashing everywhere.

[0030] An exhaust fan 58 and a filter box 59 are fixedly installed on the top of the mounting frame 51, and the exhaust fan 58 and the filter box 59 are fixedly connected. A filtering device is provided inside the filter box 59, and the filtering device can filter and collect the sucked-up plastic particles. The output end of the filter box 59 is fixedly connected to a connecting pipe 510, and the output end of the connecting pipe 510 is fixedly connected to a dust hood 511. The exhaust fan 58 generates negative pressure, and then absorbs the plastic particles on the lower mold base 3 moving below into the filter box 59 through the connecting pipe 510 and the dust hood 511, and then collects these plastic particles.

[0031] Figure 1-Figure 5 A second embodiment is shown, which mainly differs from the first embodiment in that one end of the outer wall of the two rotating rods 63 passes through one side of the outer wall of the bracket 61, and is fixedly installed with a gear 64. The two gears 64 are meshed with each other, and an L-shaped plate 65 is fixedly installed on one side of the outer wall of the bracket 61. Since the two gears 64 are meshed, when one gear 64 and the rotating rod 63 rotate, it will drive the other gear 64 and the rotating rod 63 to rotate in the opposite direction.

[0032] A motor 66 is fixedly mounted on the outer wall of the L-shaped plate 65 . The output end of the motor 66 passes through the outer wall of the L-shaped plate 65 and is fixedly connected to the outer wall of one of the two gears 64 .

[0033] The outer walls of the two rotating rods 63 are fixedly sleeved with two connecting plates 67, and a limiting roller 68 is rotatably installed between the opposite sides of each two of the four connecting plates 67. When the two rotating rods 63 rotate in opposite directions, they will drive the two limiting rollers 68 to rotate in opposite directions, so that the two limiting rollers 68 approach each other or move away from each other. When the two limiting rollers 68 move away from each other, the two limiting rollers 68 will rise. When the limiting rollers 68 do not limit the plastic lunch box below, the two limiting rollers 68 can be raised to a certain height to prevent the limiting rollers 68 from being too low and affecting the movement of the lower mold base 3. When the plastic lunch box below needs to be limited, the two limiting rollers 68 can be made to rotate close to each other, thereby causing the two limiting rollers 68 to descend until they contact the plastic lunch box below. This causes the limiting rollers 68 to be above the plastic lunch box during movement.

[0034] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0035] During operation, when it is necessary to trim the plastic lunch boxes, first place multiple plastic lunch boxes in the die 4 respectively, then turn on the electric slide 2, move the lower die base 3 and the plastic lunch boxes to the other end of the electric slide 2, at this time the lower die base 3 and the upper die base 54 are aligned, then turn on the electric push rod 52, the electric push rod 52 drives the upper die base 54 and a set of punches 55 to descend, and then the punch 55 trims the plastic lunch boxes below. Since a protective frame 56 and a flexible protective cover 57 are provided under the upper die base 54, the punch When the mold 55 is trimming, the flexible protective cover 57 will fit tightly with the lower mold base 3 below, so that the splashing plastic particles generated by the trimming of the plastic lunch box will be blocked by the protective frame 56 and the flexible protective cover 57 and will not splash everywhere, preventing the splashing plastic particles from causing harm to the nearby personnel, and also facilitating the subsequent collection of the plastic particles. When the trimming of the plastic lunch box is completed, the electric push rod 52 is turned on again, and the electric push rod 52 drives the upper mold base 54 to rise, and the splashing plastic particles will fall on the lower mold base 3, and then the electric slide rail 2 is turned on, and the electric slide rail 2 drives the lower mold base 3 and the trimmed lunch box to move outward. At this time, the exhaust fan 58 can be turned on, and the exhaust fan 58 generates negative pressure, and then through the connecting pipe 510 and the dust cover 511, the plastic particles on the lower moving mold base 3 are adsorbed into the filter box 59, and then these plastic particles are collected. At the same time, in order to prevent the suction force of the dust cover 511 from being too strong to cause the plastic lunch box to move, the motor 66 can be turned on, and the motor 66 drives a gear 64 and a rotating rod 63 Rotation, when one gear 64 rotates, it will drive the other gear 64 and the rotating rod 63 to rotate in the opposite direction. When the two rotating rods 63 rotate in the opposite direction, the two limiting rollers 68 below will be driven to approach each other, thereby causing the two limiting rollers 68 to drop until they contact the plastic lunch box below. In this way, the limiting rollers 68 are above the plastic lunch box during the movement of the plastic lunch box, which can limit the plastic lunch box under the dust cover 511, preventing the plastic lunch box from moving due to excessive suction of the dust cover 511.
