Description

Technical Field

[0001] This utility model relates to the field of safe operation technology, specifically a safe operation sensing device for a molding machine. Background Technology

[0002] As a core piece of equipment in the manufacturing industry for shaping materials and processing components, molding machines are widely used in injection molding, stamping, die casting, rubber vulcanization and other fields. Their working principle is usually to drive the mold to close, apply pressure or heat through mechanical mechanisms, so that the raw materials can be formed in the mold cavity. In the actual production process, the operation of molding machines involves high-speed moving mechanical parts (such as sliders, injection rods, mold opening and closing mechanisms) and high pressure and high temperature conditions. There are significant safety risks in the operating area. If operators accidentally come into contact with the dangerous area, it is easy to cause safety accidents such as pinching and burns. Therefore, extremely high requirements are placed on the safety protection design of molding machines.

[0003] Most existing molding machines are only protected by safety doors. However, in order to improve work efficiency, many workers open the safety doors while the molding machine is still running. Without a protective structure, personnel can easily get close to the molding machine, which can easily lead to work accidents and injuries. Utility Model Content

[0004] The purpose of this invention is to provide a safety operation sensing device for a molding machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a stepping assembly is included, a housing assembly for protecting the circuit is installed on one side of the stepping assembly, and a power supply assembly for moving and controlling the on / off state is installed inside the housing assembly. A power supply protection assembly for connecting to electrical equipment is connected to one side of the power supply assembly, and an insulation isolation assembly for insulating and isolating the power supply assembly after power failure is provided at the lower end of the power supply assembly.

[0006] Preferably, the pedal assembly includes a lower housing, an airbag, a first spring, and a pedal block, wherein the airbag is installed inside the lower housing, the first spring is installed inside the airbag, and the pedal block is connected above the airbag.

[0007] By adopting the above technical solution, the power supply components can be controlled to cut off power when someone approaches.

[0008] Preferably, the box assembly includes a storage box, a vertical partition plate, and a horizontal partition plate, and the horizontal partition plate is installed inside the storage box, with the vertical partition plate connected to the front and rear sides of the horizontal partition plate;

[0009] By adopting the above technical solutions, the circuit structure of the equipment can be protected.

[0010] Preferably, the power supply component includes a telescopic rod, a movable plate, a mounting plate, a first electrode block, and a first wire. The telescopic end of the telescopic rod is connected to the movable plate. The movable plate is connected to the mounting plate on the side near the central axis of the housing component. The first electrode block is mounted on one side of the mounting plate. The terminal of the first electrode block is connected to the first wire.

[0011] By adopting the above technical solution, the power supply can be automatically cut off when someone approaches the molding machine, thus providing power outage protection.

[0012] Preferably, the power protection component includes a second electrode block, a second wire, a surge protector, and a third wire, wherein the power receiving end of the second electrode block is connected to the second wire, the end of the second wire away from the second electrode block is connected to the surge protector, and the power output end of the surge protector is connected to the third wire.

[0013] By adopting the above technical solution, damage to equipment caused by instantaneous high voltage can be avoided during power supply.

[0014] Preferably, the insulating isolation assembly includes an insulating block, a connecting plate, a guide rod, a second spring, and a pressing block, wherein the front and rear ends of the insulating block are connected to the connecting plate, the upper end of the connecting plate is connected to the guide rod, the guide rod is provided with a second spring on its outside, and the upper end of the guide rod is connected to the pressing block;

[0015] By adopting the above technical solution, the danger of the equipment automatically resetting without manual reset can be avoided.

[0016] Compared with the prior art, the beneficial effects of this application are: the device has a proximity power-off function, thereby preventing workers from approaching the molding machine before it stops, which could cause danger. After the power is cut off, the device will isolate the energized area, which can prevent the power from being turned on before the approaching personnel move to a safe position, thus preventing danger.

[0017] When someone approaches the equipment during operation, this invention will trigger the stepping component. The change in air pressure of the stepping component will separate the power supply component from the power protection component, thus directly cutting off the power supply to the molding machine and stopping the molding machine from working, ensuring the safety of personnel approaching the equipment.

[0018] After the power supply component and the power protection component are separated, the insulating block will rise elastically in contact with the second spring, thereby placing the insulating block between the second electrode block and the first electrode block. This isolates the power supply component and the power protection component, preventing them from reconnecting. This ensures that nearby personnel are in a safe position before power is applied, thus guaranteeing the safe operation of the equipment. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-3 The present invention provides a technical solution: including a stepping component 1, a box component 2 for protecting the circuit is installed on one side of the stepping component 1, and a power supply component 3 for moving and controlling the on and off is installed inside the box component 2. A power supply component 4 for connecting to electrical equipment is connected to one side of the power supply component 3, and an insulation isolation component 5 for insulation isolation after power failure is provided at the lower end of the power supply component 3.

[0025] If someone approaches the equipment during operation, the stepping component 1 will be triggered. The change in air pressure of the stepping component 1 will cause the power supply component 3 to separate from the power protection component 4, which will directly cut off the power supply to the molding machine, thereby stopping the molding machine from working and ensuring the safety of personnel approaching the equipment.

[0026] The pedal assembly 1 includes a lower housing 101, an airbag 102, a first spring 103, and a pedal block 104. The airbag 102 is installed inside the lower housing 101, the first spring 103 is installed inside the airbag 102, and the pedal block 104 is connected above the airbag 102.

[0027] The step block 104 forms an elastic structure with the lower housing 101 through the first spring 103, which makes it easy for the step block 104 to reset after being stepped on, thus facilitating the next operation of the equipment. The size of the airbag 102 is the same as the internal size of the lower housing 101, so that when the step block 104 is stepped on, the air inside the airbag 102 will be compressed, causing the power supply component 3 to work.

[0028] The box assembly 2 includes a storage box 201, a vertical partition 202 and a horizontal partition 203, and the horizontal partition 203 is installed inside the storage box 201, with the vertical partition 202 connected to the front and rear sides of the horizontal partition 203.

[0029] The vertical partition 202 and the horizontal partition 203 divide the storage box 201 into multiple areas for operation, preventing the parts from being disturbed while working inside the storage box 201.

[0030] The power supply assembly 3 includes a telescopic rod 301, a movable plate 302, a mounting plate 303, a first electrode block 304, and a first wire 305. The telescopic end of the telescopic rod 301 is connected to the movable plate 302. The side of the movable plate 302 near the central axis of the housing assembly 2 is connected to the mounting plate 303. The first electrode block 304 is mounted on one side of the mounting plate 303. The terminal of the first electrode block 304 is connected to the first wire 305.

[0031] When the pedal assembly 1 is stepped on, gas enters the telescopic rod 301, causing the telescopic rod 301 to push the moving plate 302, thereby moving the mounting plate 303, separating the first electrode block 304 from the second electrode block 401, and causing the equipment to shut down. The first wire 305 is connected to the power supply to power the molding machine.

[0032] The power protection component 4 includes a second electrode block 401, a second wire 402, a surge protector 403 and a third wire 404. The power receiving end of the second electrode block 401 is connected to the second wire 402, the end of the second wire 402 away from the second electrode block 401 is connected to the surge protector 403, and the power output end of the surge protector 403 is connected to the third wire 404.

[0033] When the first electrode block 304 and the second electrode block 401 are reconnected, the current will be transmitted to the surge protector 403 through the second wire 402. At this time, the surge protector 403 will absorb the instantaneous high voltage generated in the power grid to prevent the high voltage generated when the equipment is powered on again from breaking down the circuit in the molding machine and causing damage to the molding machine. The third wire 404 is connected to the molding machine.

[0034] The insulating isolation assembly 5 includes an insulating block 501, a connecting plate 502, a guide rod 503, a second spring 504, and a pressing block 505. The front and rear ends of the insulating block 501 are connected to the connecting plate 502, the upper end of the connecting plate 502 is connected to the guide rod 503, the second spring 504 is provided on the outside of the guide rod 503, and the upper end of the guide rod 503 is connected to the pressing block 505.

[0035] After the power supply component 3 is separated from the power protection component 4, the insulating block 501 will contact the elastic rise of the second spring 504, thereby placing the insulating block 501 between the second electrode block 401 and the first electrode block 304. This isolates the power supply component 3 and the power protection component 4, preventing them from reconnecting. This ensures that personnel nearby are in a safe position before power is applied, thus ensuring the safe operation of the equipment.

[0036] Relying on the elastic structure formed between the connecting plate 502 and the storage box 201 through the guide rod 503 and the second spring 504, the insulating block 501 will rise after it loses its shielding, blocking the power supply component 3 and the power protection component 4, thus preventing the equipment from being suddenly connected to the power supply and causing danger.

[0037] The implementation principle of this application is as follows: First, connect the first wire 305 to the power supply and connect the third wire 404 to the molding machine. Then, place the equipment in front of the molding machine. When someone approaches the molding machine, they will step on the foot block 104, which will cause the gas inside the airbag 102 to be delivered to the telescopic rod 301, causing the telescopic rod 301 to extend and drive the mounting plate 303 to move, thus separating the first electrode block 304 from the second electrode block 401 to cut off the power. At the same time, the insulating block 501 will also rise under the elastic influence of the second spring 504, blocking the first electrode block 304 and the second electrode block 401. After confirming that it is safe for the approaching personnel, the insulating block 501 will be reset by pressing down the pressing block 505. At this time, the foot block 104 will be reset by the elastic force of the first spring 103, causing the first electrode block 304 to automatically reset.
