Description

Technical Field

[0001] The utility model particularly relates to an induction power-off device for cutting the sprue of a toy tire. Background Art

[0002] In the mold industry, sprue material refers to the waste material from the injection molding machine nozzle to the mold and all the way to the finished product. After the entire injection molding process is completed, the finished product is often connected to the sprue material. This material requires shearing or other secondary processing equipment to remove any remaining plastic material from the plastic product and the sprue runner, separating the product from the sprue material and obtaining a complete injection molded product.

[0003] Therefore, after injection molding, toy tires need to be manually placed on the equipment, and then the machine is operated to cut the sprue inside the toy tires. However, these production equipments lack protective devices. After manually placing the toy tires on the equipment, improper operation can easily lead to accidental contact and injury, thus increasing the risk of production accidents. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an induction power-off device for cutting the sprue of a toy tire.

The infrared sensing frame comprises a support arm with a track groove assembled with the guide frame, a metal cross bar welded to the front end of the support arm, a push-pull handle welded to the middle of the front end of the metal cross bar, an infrared sensing rod fixedly mounted below both ends of the metal cross bar, and a wire extending from the infrared sensing rod to the infrared safety protector.

[0007] Preferably, the infrared ports of the infrared sensing rods are arranged relative to each other.

[0008] Preferably, the guide frame includes a C-shaped frame body, fixed ends bent upward at both ends of the C-shaped frame body, track bars integrally formed at the upper and lower ends inside the C-shaped frame body for matching the track grooves on the support arm, and a spun stud arranged in the middle of the side of the C-shaped frame body for squeezing and fixing the support arm.

[0009] Preferably, a reinforcing rib is welded between the fixed end and the C-shaped frame.

[0010] Preferably, four guide frames are provided.

[0011] Preferably, the nozzle cutting mechanism includes a workbench, a pillar welded to the rear end of the workbench, a support plate welded to the upper end of the pillar, a stamping cylinder fixedly mounted on the support plate with the output end facing downward, an electromagnetic valve mounted on the side of the stamping cylinder, and a nozzle cutter mounted on the output end of the stamping cylinder.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0019] Example

[0020] An induction power-off device for cutting the water nozzle of a toy tire, such as Figure 1-5 As shown, it includes a nozzle cutting mechanism 1, an infrared safety protector 2 assembled on the nozzle cutting mechanism 1 and capable of automatically controlling the start and stop of the nozzle cutting mechanism 1, a plurality of guide frames 3 fixedly mounted on both sides of the nozzle cutting mechanism 1 by bolts, and an infrared sensing frame 4 assembled from the nozzle cutting mechanism 1 through the guide frame 3 and electrically connected to the infrared safety protector 2.

[0021] The sprue cutting mechanism 1 includes a workbench 11, a pillar 12 welded to the rear end of the workbench 11, a supporting plate 13 welded to the upper end of the pillar 12, a stamping cylinder 14 fixedly mounted on the supporting plate 13 with the output end facing downward, an electromagnetic valve 15 mounted on the side of the stamping cylinder 14, and a sprue cutter 16 mounted on the output end of the stamping cylinder 14. Specifically, the sprue cutter 16 is close to the workbench 11 and can perform sprue cutting processing on the toy tire placed on the workbench 11.

[0022] The guide frame 3 comprises a C-shaped frame body 31, fixed ends 32 bent upward at both ends of the C-shaped frame body 31, track bars 33 integrally formed at the upper and lower ends of the C-shaped frame body 31 for engaging with the track grooves on the support arms 41, and a spun stud 34 provided in the middle of the side of the C-shaped frame body 31 for squeezing and securing the support arms 41. Specifically, the fixed ends 32 abut against the side of the support plate 13 and are secured thereto by bolts.

[0023] A reinforcing rib 321 is welded between the fixed end 32 and the C-shaped frame 31 .

[0024] In this embodiment, four guide frames 3 are provided, specifically, to stably mount the infrared sensor frame 4 .

[0025] The infrared sensing frame 4 includes a support arm 41 with a track groove assembled with the guide frame 3, a metal cross bar 42 welded to the front end of the support arm 41, a push-pull handle 43 welded to the middle of the front end of the metal cross bar 42, an infrared sensing rod 44 fixedly installed below the two ends of the metal cross bar 42, and a wire 45 extending from the infrared sensing rod 44 to the infrared safety protector 2.

[0026] It should be further explained that by pulling the metal crossbar 42 through the push-pull handle 43, the support arm 41 slides in the guide frame 3, and the entire infrared sensor frame 4 can be adjusted to move forward and backward, thereby setting the operator's safe operating distance.

[0027] The infrared ports of the infrared sensing rods 44 are arranged relative to each other. Specifically, the distance between the two infrared sensing rods 44 is the operating area of the sprue cutting mechanism 1 where the toy tire is manually placed. Therefore, the two infrared sensing rods 44 can timely sense the operator's hands, and feedback is given to the infrared safety protector 2 to control the sprue cutting mechanism 1 to cut off the power and pause. After detecting that the operator's hands are removed, the infrared safety protector 2 is fed back again to control the sprue cutting mechanism 1 to power on and operate.

[0028] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention, and the implementation methods of the present invention are not limited thereto. All other modifications, replacements or changes made to the above structure of the present invention based on the above contents of the present invention, in accordance with common technical knowledge and customary means in this field, without departing from the above basic technical ideas of the present invention, should fall within the scope of protection of the present invention.
