Description

TECHNICAL FIELD

[0001] The utility model relates to a plastic injection molding edge material removal device, and particularly relates to a plastic injection molding edge material removal device. BACKGROUND

[0002] At present, in the plastic injection molding production process, the plastic products of injection molding are prone to edge material phenomenon at the die butt joint position, resulting in a circle of burr edge material formed at the side edge of the product, and then the burr at the outer edge of the plastic product needs to be removed before the plastic product is packaged and sold.

[0003] However, when removing the edge material at the edge of the plastic product, a corresponding scraper is used to remove the burr edge material adhered to the outer side of the edge of the plastic product. However, during the removal process, the plastic product itself is relatively light in material, and thus after removal, it is easy to float to the outside of the processing site, thereby polluting the environment of the processing site and affecting the normal operation of subsequent machinery. Therefore, we propose a plastic injection molding edge material removal device. UTILITY MODEL CONTENT

[0004] The main purpose of the utility model is to provide a plastic injection molding edge material removal device that can effectively solve the problems in the background art.

[0005] To achieve the above-mentioned purpose, the technical scheme adopted by the utility model is as follows:

[0006] A plastic injection molding edge material removal device, comprising a processing table, a rotating table is rotatably installed on the inner side of the processing table, an installation frame is fixedly installed on the top of the rotating table, a hydraulic cylinder is fixedly installed vertically on the middle end of the installation frame, and a pressing plate is installed on the bottom of the piston rod of the hydraulic cylinder;

[0007] A fixed plate is fixedly installed on the middle end of the side edge of the top of the processing table, an electric push rod is fixedly installed on the side edge of the fixed plate, an installation plate is fixedly installed on the side edge of the transmission shaft of the electric push rod through a coupling, and a scraper is fixedly installed on the middle end of the side edge of the installation plate;

[0008] A connecting plate is fixedly installed on the surface of both ends of the side edge of the installation plate, a material extraction mechanism is arranged on the outer side of the connecting plate, a waste storage tank is fixedly installed on both sides of the top of the processing table, and the material extraction mechanism and the waste storage tank are connected.

[0009] Through the above technical scheme, through the communication effect of the material suction mechanism, when the scraper is scraped at the outside edge of the plastic product placed on the surface of the rotating table, the burr edge material is immediately sucked into the inside of the feeding pipe by negative pressure after falling, and then is transported to the inside of the waste storage tank through the connecting pipe and the conveying hose, so that the burr edge material is collected and processed, and the burr edge material of the plastic product is prevented from being scattered randomly to pollute the construction environment and damage other machines.

[0010] As an optional solution of the technical scheme of the application, the material suction mechanism comprises a material collecting pipe and a conveying hose, each side middle end of the connecting plate is vertically fixedly installed with a feeding pipe, each side middle end of the feeding pipe is fixedly communicated with a connecting pipe, each side of the connecting pipe is fixedly communicated with a conveying hose, the top of the processing table is fixedly installed with an air suction pump, the air inlet of the air suction pump is fixedly communicated with the side of the conveying hose, the side of the feeding pipe is provided with a feeding groove, the number of the feeding grooves is several groups, and the exhaust port of the air suction pump is communicated with the bottom of the waste storage tank.

[0011] Through the above technical scheme, through the operation of the air suction pump and the communication and conveying effect of the feeding pipe and the conveying hose, the burr edge material scraped and separated by the scraper can be sucked and transported to the inside of the waste storage tank for collection, so that the burr edge material is prevented from being scattered randomly to interfere with the construction site.

[0012] As an optional solution of the technical scheme of the application, the bottom middle end of the processing table is fixedly installed with a fixed frame, the inside middle end of the fixed frame is fixedly installed with a rotating motor, and the top of the transmission shaft of the rotating motor is fixedly connected with the bottom of the rotating table through a shaft coupling.

[0013] Through the above technical scheme, the rotating motor can provide the power required for the rotation of the rotating table and the plastic product placed on the surface thereof.

[0014] As an optional solution of the technical scheme of the application, the outside middle end of the rotating table is fixedly installed with a guide sliding block, and the inside of the processing table is provided with a guide sliding groove, and the guide sliding block is slidingly inserted into the guide sliding groove.

[0015] Through the above technical scheme, through the guide sliding effect of the guide sliding groove on the guide sliding block, the rotation stability of the rotating table can be ensured.

[0016] Compared with the prior art, the application has the following beneficial effects:

[0017] 1. The present application discloses a plastic injection molding edge removal device, which includes a rotating table inside the processing table and a scraper outside the rotating table. Feeding pipes are installed on the sides of connecting plates on both sides of the scraper. During the operation of the vacuum pump, negative pressure suction is generated inside the feeding pipe and feeding trough through the conveying hose and connecting pipe. This causes the scraper to scrape and deburr the outer edge of the plastic product placed on the rotating table surface. As the scraper falls off, the burr edge material is immediately sucked into the feeding pipe by the negative pressure and then transported to a waste storage tank through the connecting pipe and conveying hose for collection. This prevents the burr edge material from scattering and polluting the construction environment or damaging other machinery.

[0018] 2. The edge removal device for plastic injection molding according to the present application connects the feed pipe and the waste storage tank through a corrugated conveying hose. With the extension and deformation of the corrugated conveying hose itself, the connection between the feed pipe and the waste storage tank can still be maintained after the horizontal position of the scraper is adjusted by the operation of the electric push rod, thereby ensuring the stability of the overall mechanism in absorbing and conveying plastic edge burrs.

[0023] like Figures 1-3 As shown, this utility model provides a technical solution: a plastic injection molding edge removal device, wherein a rotating table 11 is rotatably installed on the inner side of the processing table 1, a mounting frame 12 is fixedly installed on the top of the rotating table 11, a hydraulic cylinder 13 is vertically fixedly installed in the middle of the mounting frame 12, and a pressure plate 14 is installed at the bottom of the piston rod of the hydraulic cylinder 13.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a fixing plate 2 is fixedly installed on the middle of the top side of the processing table 1. An electric push rod 21 is fixedly installed on the side of the fixing plate 2. An mounting plate 22 is fixedly installed on the side of the drive shaft of the electric push rod 21 through a coupling. A scraper 23 is fixedly installed on the middle of the side of the mounting plate 22.

[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), a fixed frame 15 is fixedly installed at the bottom center of the processing table 1. A rotating motor 16 is fixedly installed at the inner center of the fixed frame 15. The top of the drive shaft of the rotating motor 16 is fixedly connected to the bottom of the rotating table 11 through a coupling. A guide slider 4 is fixedly installed at the outer center of the rotating table 11. A guide groove 41 is opened on the inner side of the processing table 1, and the guide slider 4 is slidably inserted into the guide groove 41.

[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), the material extraction mechanism includes a material collection pipe and a conveying hose 31. Each connecting plate 24 has a feeding pipe 25 fixedly installed vertically at the middle of its side. Each feeding pipe 25 has a connecting pipe 27 fixedly connected to its middle of its side. Each connecting pipe 27 has a conveying hose 31 fixedly connected to its side. Both sides of the top of the processing table 1 are fixedly installed with air pumps 28, and the air inlet of the air pump 28 is fixedly connected to the side of the conveying hose 31. The side of the feeding pipe 25 has a feeding groove 26, and there are several sets of feeding grooves 26. The exhaust port of the air pump 28 is connected to the bottom of the waste storage tank 3.

[0027] During operation, the plastic product requiring edge removal is placed on the surface of the rotating table 11. Then, the hydraulic cylinder 13 is activated via an external control switch, causing it to rotate and drive the pressing plate 14 to descend vertically in sync. This allows the bottom surface of the pressing plate 14 to adhere to the top surface of the plastic product, ensuring the product is stably placed on the rotating table 11. Next, the electric actuator 21 is activated via an external control switch, causing it to rotate and move the mounting plate 22 and connecting plate 24 horizontally in sync until the side of the scraper 23 adheres to the outer side of the plastic product. Finally, the rotating motor 16 is activated via an external control switch, causing it to rotate under the guiding sliding action of the guide groove 41 on the guide slider 4. This allows the rotating table 11 to rotate synchronously inside the processing table 1, so that the plastic products placed on its surface can be scraped and removed by the scraper 23 during the rotation. At the same time, the vacuum pump 28 is started, which causes the conveying hose 31 and connecting pipe 27 to generate negative pressure suction inside the feeding pipe and feeding trough 26. As the scraper 23 scrapes and removes burrs from the outer edge of the plastic products placed on the rotating table 11, the burrs that fall off are immediately sucked into the feeding pipe by the negative pressure, and then transported to the waste storage tank 3 for collection and treatment through the connecting pipe 27 and conveying hose 31.
