Description

Technical Field

[0001] This utility model relates to the field of plastic mold technology, specifically to a cutting mechanism for plastic molds. Background Technology

[0002] Plastic molds are the most common type of plastic mold, used to produce various plastic parts, such as automotive interior parts, electronic product casings, toys, etc. Their working principle is to inject molten plastic into the mold cavity through an injection molding machine, and after cooling and solidification, the desired plastic product is formed.

[0003] The cutting mechanism of plastic molds is mainly used for the separation or trimming of plastic parts after molding. Common types use a power source to synchronously drive two sets of blades to move in opposite directions, which can accurately cut the gate, flash or continuous profile of plastic parts. It has the characteristics of high cutting efficiency, flat cross-section and small positioning error. It is suitable for trimming injection molds and cutting extruded pipes and profiles. However, the current cutting mechanism of plastic molds often lacks the ability to cut plastic molds to a fixed length and classify plastic molds of different batches at the same time, so the cutting efficiency needs to be improved.

[0004] In view of this, we propose a cutting mechanism for plastic molds. Utility Model Content

[0030] Please see Figures 1-4 This utility model provides a technical solution:

[0031] A cutting mechanism for plastic molds includes a base 1, a vertical plate 2 fixedly mounted on the top of the base 1, and a bracket 3 fixedly mounted on the top of the base 1.

[0032] In one embodiment of this utility model, a cutting assembly 4 is provided on the base 1. The cutting assembly 4 includes a U-shaped frame 41. The U-shaped frame 41 is fixedly installed at one end of the vertical plate 2. A first motor 42 is fixedly installed on the side wall of the U-shaped frame 41. A driving gear 43 and a driven gear 44 are rotatably installed at one end of the vertical plate 2 via a rotating shaft 45. The rotating shaft 45 is rotatably installed inside the vertical plate 2 via bearing components. The driving gear 43 meshes with the driven gear 44. The output end of the first motor 42 is fixedly connected to the rotating shaft 45. An eccentric wheel 46 is fixedly installed on the outside of the rotating shaft 45. A ring 47 is rotatably installed on the outside of the eccentric wheel 46 via bearing components. A connecting plate 48 is fixedly installed at one end of the ring 47. A slot is opened at the other end of the connecting plate 48. One end of an L-shaped frame 49 is fixedly installed at the other end of the ring 47, and a cutting blade 410 is fixedly installed at the other end of the L-shaped frame 49. A rectangular block 411 is fixedly installed on the outer wall of the vertical plate 2. A slide rod 412 is slidably installed inside the rectangular block 411. A limit ring 413 is fixedly installed on the outside of the slide rod 412. The slide rod 412 slides against the groove inside the connecting plate 48. A first conveyor belt 414 and a second conveyor belt 415 are provided on the vertical plate 2. Two sets of rotating shaft 45, eccentric wheel 46, ring 47, connecting plate 48, L-shaped frame 49, cutting blade 410, rectangular block 411, and slide rod 412 are provided. Multiple sets of limit rings 413 are provided. The first conveyor belt 414 and the second conveyor belt 415 are located at the same horizontal height.

[0033] In this embodiment, when cutting the plastic mold is required, the first motor 42 is started. The first motor 42 drives the rotating shaft 45 to rotate. Through the meshing transmission of the driving gear 43 and the driven gear 44, the power is transmitted to another set of rotating shafts 45, so that the two sets of rotating shafts 45 rotate synchronously. As the rotating shafts 45 rotate, the eccentric wheel 46 performs eccentric circular motion, and the ring 47 performs regular reciprocating motion with the eccentric wheel 46. The slide rod 412 is installed inside the rectangular block 411 and can slide. The limiting ring 413 limits the slide rod 412. Driven by the eccentric wheel 46 and the ring 47, the connecting plate 48 moves along the slide rod 41. 2. The reciprocating linear motion drives the two sets of L-shaped frames 49 and the cutting blades 410 to move synchronously away from or towards each other. When the two sets of cutting blades 410 approach each other, the cutting action on the plastic mold is achieved. The first conveyor belt 414 and the second conveyor belt 415 transport the plastic mold at a fixed speed and distance. Since the two sets of eccentric wheels 46 in the cutting assembly 4 move away from or towards each other synchronously to cut, combined with the fixed conveying distance of the first conveyor belt 414 and the second conveyor belt 415, and the eccentric wheel 46 drives the ring 47 to rotate one revolution, the conveyed plastic mold is cut to a fixed length, thereby achieving fixed-length cutting of the plastic mold.

[0034] In one embodiment of this utility model, a sorting component 5 is provided on the base 1. The sorting component 5 includes a second motor 51. The second motor 51 is fixedly installed on the outer wall of the bracket 3. A rotating rod 52 is rotatably installed inside the bracket 3 through a bearing component. The output end of the second motor 51 is fixedly connected to the rotating rod 52. A rotating plate 53 is fixedly installed on the outside of the rotating rod 52. A collection box 54 is placed on the top of the base 1. Two sets of collection boxes 54 are provided. The collection boxes 54 are respectively placed at both ends of the rotating plate 53.

[0035] In this embodiment, when it is necessary to classify the cut plastic molds, the second motor 51 is started. As the rotating rod 52 rotates, the rotating plate 53 rotates with the rotating rod 52. By controlling the second motor 51, the operator can make the rotating plate 53 rotate to different angles via the rotating rod 52. Two sets of collection boxes 54 are located at both ends of the rotating plate 53. The cut plastic molds fall onto the rotating plate 53. When the rotating plate 53 rotates to different angles, the plastic molds fall into the corresponding collection boxes 54 under the action of gravity, thereby realizing the classified storage of plastic molds cut in different batches and improving the overall efficiency of the cutting work.

[0036] All electrical components mentioned in this application are electrically connected to the PLC controller and 220V AC mains power. The PLC controller is a conventional and known device capable of controlling the first motor 42, the first conveyor belt 414, the second conveyor belt 415, and the second motor 51. All standard parts used in this application can be purchased from the market.
