Description

Technical Field

[0001] The invention relates to the technical field of tail plate transportation of injection molding machines, in particular to a lifting device in injection molding machine tail plate casting production equipment. Background Art

[0002] In the casting production process of the tail plate of the injection molding machine, the lifting device plays a vital role. They are not only responsible for efficiently and safely transporting the cast tail plate from the production line to the sand-falling machine for subsequent processing, but also directly affect the automation degree and production efficiency of the entire production line. Traditionally, the lifting device of the tail plate of the injection molding machine is mainly transported by a conveyor roller. However, during the transportation process, the contact area between the conveyor roller and the tail plate of the injection molding machine is small, resulting in insufficient friction between the conveyor roller and the tail plate of the injection molding machine during transportation, causing the tail plate of the injection molding machine to slide backwards, causing the tail plate of the injection molding machine to Slipping off the conveyor roller can easily cause harm to the safety of the operator, or cause multiple injection molding machine tail plates to collide with each other on the conveyor roller, causing the injection molding machine tail plate to be damaged and unable to meet the use requirements. In addition, the injection molding machine tail plate after casting is transported to the sand drop machine through the conveyor roller. During the transportation process, the injection molding machine tail plate will be pre-treated with sand cleaning, causing the molding sand outside and inside the injection molding machine tail plate to fall to the outer wall of the conveyor roller, which can easily cause the friction between the conveyor roller and the injection molding machine tail plate to further reduce, and the fallen molding sand enters the inside of the conveyor roller shaft, thereby causing damage to the equipment.

[0014] Compared with the prior art, the advantages of the present invention are:

[0015] 1. The present invention cooperates between the eccentric roller and the sliding frame. During the process of transporting the tail plate of the injection molding machine by the conveyor belt, the motor three drives the eccentric roller to rotate, so that the eccentric roller drives the upper tail plate of the injection molding machine to vibrate, and performs sand removal pretreatment through vibration. At the same time, the motor one drives the two sliding frames to slide alternately, so that the two sliding frames drive the tail plate of the injection molding machine to collide in the left and right directions in sequence. The tail plate of the injection molding machine improves the vibration effect and the effect of sand removal pretreatment during the transportation of the conveyor belt through collision. The eccentric roller and the sliding frame drive the tail plate of the injection molding machine to perform sand removal pretreatment, which can ensure that during the transportation process, the molding sand outside the tail plate of the injection molding machine falls off and the molding sand inside is loose.

[0016] 2. The present invention designs a spring 1, a scraper hole, a spring 2 and a rotating ring. When the sliding frame slides, the sliding frame drives the scraper hole and the rotating ring to scrape off the molding sand on the outer peripheral walls of the rotating roller and the eccentric roller. At the same time, the spring 1 and the spring 2 cooperate with the rotation of the rotating roller and the eccentric roller, so that the spiral steel rings of the spring 1 and the spring 2 further clean the molding sand on the outer peripheral walls of the rotating roller and the eccentric roller. By cleaning the rotating roller with the spring 1 and the scraper hole and cleaning the eccentric roller with the spring 2 and the rotating ring, the cleanliness of the outer peripheral walls of the rotating roller and the eccentric roller can be ensured, and the molding sand can be prevented from entering the interior of the rotating roller and the eccentric roller shaft to cause equipment damage.

[0017] 3. The present invention cooperates between the conveyor belt and the sliding frame. During the process of transporting the tail plate of the injection molding machine by the conveyor belt, when the sliding frame moves, the sliding frame drives the second side plate to move, so that the second side plate hits the tail plate of the injection molding machine above the feeding conveyor. After the two sliding frames hit the tail plate of the injection molding machine once in turn, the two sliding frames return to their positions and remain stationary. At this time, the feeding conveyor transports the tail plate of the injection molding machine to the top of the conveyor belt. When the tail plate of the injection molding machine is pre-treated by sand removal, the baffle plate of the side wall of the conveyor belt hits the side wall of the tail plate of the injection molding machine, so that the tail plate of the injection molding machine is stationary relative to the conveyor belt. Through the contact between the second side plate and the baffle plate, the distance between the tail plate of the injection molding machine above the conveyor belt is ensured to be constant, thereby avoiding the tail plates of the injection molding machine from hitting each other above the conveyor belt.

[0029] A lifting assembly is movably installed between the fixing frame 13 and the fixing seat 1, and the lifting assembly is used to adapt to the height of the discharge platform when the tail plate is transported to the sand shakeout machine.

[0030] Among them, the rotating roller 31 drives the conveyor belt 22 to transport the tail plate of the injection molding machine. During the process of the conveyor belt 22 transporting the tail plate of the injection molding machine, the eccentric roller 32 rotates and intermittently contacts the conveyor belt 22, causing the tail plate of the injection molding machine to vibrate and desand. The baffle 221 contacts the side wall of the tail plate of the injection molding machine to prevent the tail plate of the injection molding machine from sliding backward during the vibration process.

[0031] like Figure 6 and Figure 7 As shown, a sliding ball 215 is integrally formed at the connection between the two side panels 3 212 and the rotating rod 213, and a sliding groove 3 216, an annular groove 217 and a spiral groove 218 are provided on the side wall of the rotating rod 213. The sliding groove 3 216, the annular groove 217 and the spiral groove 218 are interconnected, and the sliding ball 215 is slidably installed inside the sliding groove 3 216, the annular groove 217 and the spiral groove 218. The side wall of the side panel 1 131 is fixedly installed with a motor 132, and the output shaft of the motor 132 is fixedly connected with an intermittent gear 133, and the side wall of the rotating rod 213 is fixedly installed with a gear 1 214, and the intermittent gear 133 and the gear 1 214 are meshed.

[0032] Among them, the working principle of the sliding frame 21 is: start the motor 132, the intermittent gear 133 and the gear 1 214 are meshed with each other, the rotating rod 213 rotates, the sliding groove 3 216 and the spiral groove 218 are both one-fifth of the circle of the outer peripheral wall of the rotating rod 213, and the annular groove 217 is three-fifths of the circle of the outer peripheral wall of the rotating rod 213. When the sliding ball 215 slides from the inside of the annular groove 217 to the inside of the sliding groove 3 216, the sliding frame 21 moves in the direction of the conveyor belt 22. When the sliding ball 215 slides from the inside of the sliding groove 3 216 to the inside of the spiral groove 218, the sliding frame 21 is reset. When the sliding ball 215 slides in the inside of the annular groove 217, the sliding frame 21 is stationary. Each time the intermittent gear 133 and the gear 1 214 are meshed, the gear 1 214 only rotates one circle. Every time the rotating rod 213 rotates one circle, the two sliding frames 21 move alternately once and stand still for one-fifth of a circle.

[0033] like Figure 3-Figure 5 As shown, a rotating hole 231 and a scraping hole 232 are provided on the side wall of the sliding frame 21, and the rotating roller 31 is rotatably installed inside the scraping hole 232. A plurality of uniformly distributed springs 1 314 are provided between the fixed frame 13 and the scraping hole 232, and the spring 1 314 corresponds to the rotating roller 31 one to one, and the rotating roller 31 is rotatably installed inside the spring 1 314. A rotating ring 325 is fixedly installed on the side wall of the eccentric roller 32, and the rotating ring 325 is rotatably installed inside the rotating hole 231. A plurality of uniformly distributed springs 2 324 are provided between the sliding frame 21 and the fixed frame 13, and the spring 2 324 corresponds to the eccentric roller 32 one to one, and the rotating ring 325 is rotatably installed on the side wall of the spring 2 324, and the eccentric roller 32 is rotatably installed inside the spring 2 324. A protrusion 326 is integrally formed on the side wall of the spring 2 324, and a sliding groove 135 is provided on the side wall of the fixed frame 13, and the protrusion 326 is slidably installed inside the sliding groove 135.

[0034] Among them, when the sliding frame 21 slides into the interior of the sliding groove three 216, the spring one 314 and the spring two 324 both release their elastic force, so that the sliding frame 21 quickly slides toward the conveyor belt 22 and contacts the tail plate of the injection molding machine, so that the tail plate of the injection molding machine shakes and removes sand, thereby improving the sand removal efficiency in the process of the conveyor belt 22 transporting the tail plate of the injection molding machine. During the sliding process of the sliding frame 21, the scraping hole 232 and the rotating ring 325 respectively scrape the molding sand on the outer peripheral wall of the rotating roller 31 and the eccentric roller 32, and the spring one 314 and the spring two 324 are tightly attached to the outer peripheral wall of the rotating roller 31 and the eccentric roller 32, so that the rotating roller 31 and the eccentric roller 32 are located on the outer peripheral wall between the sliding frame 21 and the fixed frame 13, and the molding sand is scraped off by the spiral steel rings on the side walls of the spring one 314 and the spring two 324, so as to prevent the molding sand from entering the rotating shaft of the rotating roller 31 and the eccentric roller 32.

[0035] Further references Figure 3 and Figure 4To explain, the working principle of the protrusion 326 is: during the rotation of the eccentric roller 32, the eccentric roller 32 drives the spring 324 to move, and the protrusion 326 slides inside the slide groove 135, so that the eccentric roller 32 rotates inside the spring 324.

[0036] like Figure 1 and Figure 6 As shown, the side walls of the two sliding frames 21 are integrally formed with a second side plate 211 , and the second side plate 211 is located on a side close to the feeding platform 12 .

[0037] Among them, when the sliding frame 21 slides, the side plate 211 contacts the tail plate of the injection molding machine on one side of the feed table 12 to prevent the tail plate of the injection molding machine from colliding inside the vibration assembly. When the two sliding frames 21 are both stationary, the tail plate of the injection molding machine moves to the top of the conveyor belt 22. Through the contact of the side plate 211, the distance between the tail plates of the injection molding machines on the outside of the conveyor belt 22 is ensured to prevent the tail plates of the injection molding machines from stacking and colliding during transportation.

[0038] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the side walls of the two fixed frames 13 are respectively fixedly installed with motor 2 311 and motor 3 321, the output shaft of motor 2 311 is fixedly connected to the side wall of one of the rotating rollers 31, the side wall of each rotating roller 31 is fixedly installed with sprocket 1 312, the outer side of sprocket 1 312 is wound with chain 1 313, the output shaft of motor 321 is fixedly connected to the side wall of one of the eccentric rollers 32, the side wall of each eccentric roller 32 is fixedly installed with sprocket 2 322, the outer side of sprocket 2 322 is wound with chain 2 323.

[0039] like Figure 1 As shown, the lifting assembly includes a jack 11 and a connecting frame 112. The jack 11 is fixedly installed at the bottom of the fixing base 1. The connecting frame 112 is rotatably installed on the side wall of the fixing frame 13. The output end of the jack 11 and the side wall of the connecting frame 112 are rotatably connected. A slide groove 111 is provided on the side wall of the fixing base 1. A slider 134 is integrally formed on the side wall of the fixing frame 13. The slider 134 is slidably installed inside the slide groove 111.

[0040] The specific working principle and use method of the present invention are explained in detail below: start the motor 132, the motor 2 311 and the motor 321, the motor 2 311 drives the rotating roller 31 to rotate, the rotating roller 31 rotates and drives the conveyor belt 22 to move, the conveyor belt 22 drives the tail plate of the injection molding machine above to move toward the sand falling machine, the motor 321 drives the eccentric roller 32 to rotate, when the conveyor belt 22 drives the tail plate of the injection molding machine above to move above the eccentric roller 32, the eccentric roller 3 2 drives the tail plate of the injection molding machine to vibrate, so that the tail plate of the injection molding machine cleans the molding sand on the outside through vibration and loosens the molding sand inside. The motor 132 drives the rotating rod 213 to rotate, so that the sliding ball 215 slides from the ring groove 217 into the sliding groove 3 216. At this time, the spring 1 314 and the spring 2 324 drive the sliding frame 21 to move quickly toward the conveyor belt 22. The sliding frame 21 resists and pushes the tail plate of the injection molding machine, so that the tail plate of the injection molding machine hits the sliding frame 21 on the other side, and the injection molding machine is improved by the impact of the tail plate of the injection molding machine. In order to loosen the molding sand inside the tail plate of the molding machine, when the sliding frame 21 moves toward the conveyor belt 22, the sliding frame 21 uses the scraping hole 232 and the rotating ring 325 to scrape the molding sand on the outer peripheral wall of the rotating roller 31 and the eccentric roller 32 to prevent the molding sand from entering the interior of the rotating shaft of the rotating roller 31 and the eccentric roller 32. At the same time, through the rotation of the rotating roller 31 and the eccentric roller 32, the spiral steel rings of the spring 1 314 and the spring 2 324 further clean the molding sand on the outer peripheral wall of the rotating roller 31 and the eccentric roller 32, thereby improving the cleaning effect of the molding sand on the outer peripheral wall of the rotating roller 31 and the eccentric roller 32. The cleanliness of the core roller 32, in the process of the two sliding frames 21 moving in sequence, the side plate 211 contacts the tail plate of the injection molding machine above the feeding conveyor 121, when the two sliding frames 21 hit the tail plate of the injection molding machine in sequence, the two sliding frames 21 return to their positions and remain stationary, at this time the feeding conveyor 121 conveys the tail plate of the injection molding machine to the top of the conveyor belt 22, through the contact of the side plate 211, the spacing of the tail plate of the injection molding machine above the conveyor belt 22 is ensured, avoiding the tail plates of the injection molding machine from colliding with each other above the conveyor belt 22.

[0041] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.
