Description

Technical Field

[0001] The invention relates to the technical field of injection molding equipment, in particular to automatic injection molding feeding equipment for producing mobile phone shells. Background Art

[0002] Injection molding machines are used to make thermoplastics or thermosetting materials into plastic products of various shapes. Plastic injection molding is a method of producing plastic products. The injection mold is installed on the injection molding machine, and the molten plastic is injected into the plastic product mold under pressure. The desired plastic parts are obtained by cooling and molding.

[0003] Most of the plastic products we see in daily life are produced by injection molding machines or blow molding machines. In the production process of plastic products using injection molding machines and blow molding machines, a large amount of plastic pellets are consumed. The hoppers of injection molding machines and blow molding machines are mostly set on the top of the equipment. The opening is located at a high position, which is difficult for operators to reach. Steps or ladders are required to add materials, which is highly dangerous and labor-intensive. In addition, in the production process of large quantities of plastic products, several equipment are generally set up in the workshop to produce at the same time, requiring more operators to fill, consuming greater labor costs.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-6 , the present invention provides a technical solution:

[0031] An automatic injection molding feeding equipment for producing mobile phone cases includes a group of top slide rails 1, top hanging plates 2 are slidably connected between the top slide rails 1, a feeding barrel 3 is slidably provided at the bottom of the top hanging plate 2, an outer shaft 4 is rotatably connected inside the feeding barrel 3, and the outer shaft 4 is fixedly connected with fan blades 5 and stirring rods 6 in sequence from top to bottom, a suction pipe 7 is connected to the outer wall of the feeding barrel 3, a bellows 8 is fixedly connected to the end of the suction pipe 7, and a preheating sleeve 9 is fixedly installed on the outer wall, a partition filter fence 10 is fixedly connected inside the feeding barrel 3, a discharge valve plate 11 is slidably connected to the bottom of the feeding barrel 3, a discharge motor 12 is fixedly installed at the bottom of the top hanging plate 2, a discharge screw 13 is fixedly installed at the output end of the discharge motor 12, the discharge screw 13 passes through the outer shaft 4 and rotatably cooperates with it, and the bottom end is fixedly connected to the discharge valve plate 11.

[0032] In order to facilitate the automatic loading of each injection molding machine in the injection molding workshop, save manpower and time, and improve production efficiency, the present invention fixes a top hanging plate 2 on the top of the injection molding workshop, places a storage box 31 or other storage facilities on the workshop floor, connects the bellows 8 of the feeding barrel 3 with the storage box 31, and inserts it between the materials inside the storage box 31 to fill the bottom of the bellows 8, and then rotates by connecting the outer shaft 4, so that the internal fan blades 5 and the stirring rod 6 rotate synchronously, so that the fan blades 5 rotate rapidly to generate a large suction force to suck the material from the storage box 31 into the suction pipe 7 through the bellows 8, and then enter the feeding barrel 31 after being preheated by the preheating sleeve 9, and is blocked by the partition filter fence 10, so that it falls to the bottom, and the internal material is stirred evenly under the action of the synchronously rotating stirring rod 6, so as to achieve the effect of preheating and stirring while feeding, greatly saving manpower and material resources, and no need for manual climbing to add materials, accelerating production efficiency, improving production quality, no need for complex mechanisms, simplified structure, easy to use and control, overall flexibility, and can adapt to various workshop needs.

[0033] After a certain amount of suction is completed, the outer shaft 4 stops rotating, and then the top hanging plate 2 moves to above the feeding barrel of the machine where feeding is required, and the height of the feeding barrel 3 is driven to drop by the rotation of the unloading screw 13, thereby reducing the distance from the machine and aligning the feeding port to prevent material from scattering. When descending, the height of the unloading screw 13 remains unchanged, so the unloading valve plate 11 connected thereto moves upward relative to the feeding barrel 3, and thus moves to the inside of the feeding barrel 3, and its surroundings are not in contact with the feeding barrel 3, thereby opening the feeding barrel 3, so that the internal material automatically falls into the feeding port, realizing the automatic feeding process.

[0034] Among them, by turning on the moving motor 16, the traveling gear 17 is driven to rotate, and with the cooperation of the bottom rack 15, the moving motor 16 and the top hanging plate 2 move back and forth on the top slide rail 1, thereby realizing the function of feeding any machine in the workshop. While moving, the balance bar 18 and the auxiliary wheel 19 are used to stably connect the top hanging plate 2 between the top slide rails 1, thereby avoiding the travel gear 17 from being subjected to force, and the rolling of the auxiliary wheel 19 reduces friction, making the movement smooth; through the cooperation of the guide bar 20 with the output end of the moving motor 16 and the cooperation of the embedded slider 21 with the top slide rail 1, the top hanging plate 2 moves smoothly and will not be skewed.

[0035] The main motor 22 is started to mesh with the external gear 24 to drive the external shaft 4 to rotate rapidly, thereby making room for the unloading screw 13 to install.

[0036] The telescopic guide cylinder 25 plays a guiding and supporting role in its downward movement. When recovering, the telescopic guide cylinder 25 has a tendency to retract the top hanging plate 2 through the restoring force generated by the internal buffer spring 26, so as to facilitate its smooth retraction.

[0037] Among them, when the outer shaft 4 rotates to perform material suction and stirring, it also drives the anti-blocking scraper 27 to rotate at the bottom of the partition filter fence 10 to push off the plastic particles adsorbed thereon to avoid blocking the air outlet and affecting material suction; when the unloading screw 13 rotates the feeding barrel 3 to move downward, the partition filter fence 10 presses down the anti-blocking scraper 27 to adapt to the downward movement of the feeding barrel 3. The outer wall of the outer shaft 4 of this section is a square rod, which is slidably connected to the square hole in the middle of the anti-blocking scraper 27. A tension spring is provided between the partition filter fence 10 and the anti-blocking scraper 27 so that when the feeding barrel 3 returns to its original position, the anti-blocking scraper 27 also returns to its original position, thereby realizing the scraping effect during material suction.

[0038] Among them, a material blocking ring 28 is provided below the anti-blocking scraper strip 27. The material blocking ring 28 is bucket-shaped and fixedly connected to the inner wall of the feeding barrel 3, and is located above the connection between the suction pipe 7 and the feeding barrel 3. The material sucked into the suction pipe 7 is intercepted by the material blocking ring 28 in large quantities and enters the interior of the feeding barrel 3. A hollow material blocking plate 29 is fixedly connected to the feeding barrel 3. The hollow material blocking plate 29 is located above the stirring rod 6. During stirring, the material falling below is provided with a certain degree of protection and shielding to avoid the influence of the top airflow.

[0039] The bottom of the feed barrel 3 is bucket-shaped and fixedly connected with a discharge straight pipe 30. The discharge valve plate 11 is located in the discharge straight pipe 30 and slides with it, providing a moving space for the discharge valve plate 11, which can be synchronized with the downward movement of the feed barrel 3. The suction pipe 7 is a metal pipe, and the heating ring inside the cylinder preheating sleeve 9 is heated to transfer the heat to the suction pipe 7. When the wind passes through, it becomes hot wind, thereby preheating the passing material, reducing the melting and feeding time required for subsequent production, and improving production efficiency.

[0040] The bottom of the bellows 8 is connected to a material storage box 31, and a sealing cover 32 is slidably connected to the top of the material storage box 31. The sealing cover 32 is connected to the bellows 8, and the end of the bellows 8 is kept at a lower end position so that it can be inserted into the bottom of the material to facilitate material suction and feeding. The sealing cover 32 can move with the movement of the feeding barrel 3 through manual or electric drive, thereby reducing the length of the bellows 8, reducing losses, and facilitating feeding.
