Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, specifically to an auxiliary injection molding box for an injection molding machine. Background Technology

[0002] The auxiliary injection molding box is indispensable in injection molding production. It can pre-treat plastic raw materials, such as drying, heating, and conveying, to ensure stable raw material quality.

[0003] Utility model patent CN221212551U discloses an auxiliary injection molding box for an injection molding machine. This auxiliary injection molding box includes a support frame and an injection molding storage box located inside the support frame. A conical funnel is provided at the bottom of the injection molding storage box, and one end of its air blower pipe, away from the fan blade box, is inserted into the interior of the conical funnel. A power motor is located at the bottom of the auxiliary injection molding box, with a feeding screw and a fan blade box connected to its two ends respectively. The fan blade box and the conical funnel are connected by air blowing... In the auxiliary feeding process of the injection molding machine, the feed screw of the auxiliary injection box can feed the injection material, and the fan box can blow air to the conical funnel through the air pipe. Under the action of air blowing, the injection material can move more smoothly towards the discharge pipe. With the dual auxiliary feeding action of the feed screw and the fan box, the bottom of the auxiliary injection box of the injection molding machine is prevented from jamming or blocking, thus making the feeding of the auxiliary injection box of the injection molding machine smoother.

[0004] When this injection molding machine auxiliary injection box is in use, the plastic granules accumulate together, making it easy for the plastic granules to be heated unevenly during heating, resulting in clumping. Once the plastic granules clump together, if they are not dealt with in time, they will cause blockage of the material conveying pipe. In view of this, we propose an injection molding machine auxiliary injection box. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary injection box for injection molding machines to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An auxiliary injection molding box for an injection molding machine includes a box body, a material conveying mechanism at the bottom of the box body, a material separating structure for dispersing plastic particles inside the box body, and a material dispersing mechanism for breaking up plastic particles at the bottom of the box body.

[0009] The bulk material mechanism includes a baffle fixed inside the conveying mechanism, a stirring shaft extending into the box body, and a motor for driving the stirring shaft to rotate.

[0010] The bottom end of the baffle is provided with a base plate, and the base plate is provided with a plurality of slots;

[0011] The stirring shaft runs longitudinally through the base plate and is rotatably connected to the base plate. Several stirring rods are provided around the periphery of the stirring shaft.

[0012] Preferably, the top of the box body is provided with a box cover, and the top of the vertical cylinder passes through the box cover;

[0013] In this design, the lid prevents dust and other impurities from entering the chamber, keeping the interior clean; the vertical cylinder penetrating the lid facilitates connection to the hot air duct, allowing for the introduction of hot air.

[0014] Preferably, the top of the vertical cylinder is connected to a hot air pipe for introducing hot air, the dispersion plate is a hollow plate structure, and the outer surface of the dispersion plate is a mesh plate.

[0016] Preferably, the material conveying mechanism includes a sleeve fixed to the bottom of the box and communicating with the box body, and an auger for conveying materials. The front end of the sleeve is provided with a material conveying pipe, and the auger extends into the material conveying pipe.

[0017] In this setup, the sleeve connects the housing and the conveying pipe to form a material conveying channel. The auger rotates inside the conveying pipe and conveys the plastic granules to the subsequent equipment in a spiral pushing manner.

[0018] Preferably, the top of the base plate is provided with a conical guide cone, and the stirring shaft passes through the guide cone;

[0019] In this setup, the guide cone uses its conical structure to guide the material towards the groove in the bottom plate, making the flow of plastic granules smoother.

[0020] Preferably, a driven bevel gear is coaxially connected to the bottom end of the stirring shaft, and a driving bevel gear is coaxially connected to the end of the output shaft of the motor, wherein the driving bevel gear meshes with the driven bevel gear;

[0021] In this setup, the motor transmits power to the stirring shaft via bevel gear meshing, causing the stirring shaft to drive the stirring rod to break up the clumps of plastic particles.

[0022] Preferably, an end sleeve is fitted and fixed to the top of the stirring shaft, the stirring rod is fixedly connected to the end sleeve, and a plurality of shovels are fixed on the stirring rod;

[0023] In this configuration, the end sleeve enhances the connection stability between the stirring rod and the stirring shaft, and the shovel plate increases the contact area and force with the plastic granules, enabling the stirring rod to more powerfully scoop up and turn the granules, further improving the dispersing effect.

[0024] Preferably, the bottom end of the base plate is provided with a partition, which covers the driven bevel gear and the driving bevel gear.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0041] Please see Figures 1-7 An auxiliary injection molding box for an injection molding machine includes a box body 1. The bottom of the box body 1 is provided with a material conveying mechanism 3, and the top of the box body 1 is provided with a box cover 11. The material conveying mechanism 3 includes a sleeve 31 fixed to the bottom of the box body 1 and communicating with the inside of the box body 1, and an auger 32 for conveying materials. The front end of the sleeve 31 is provided with a material conveying pipe 311. The auger 32 extends into the material conveying pipe 311 and rotates inside the material conveying pipe 311. The plastic particles in the box body 1 are conveyed to the subsequent processing equipment through the material conveying pipe 311 by a spiral pushing method.

[0042] like Figure 1 and Figure 2 As shown, in this invention, a separating structure 2 for dispersing plastic particles is provided inside the housing 1. The separating structure 2 includes a hollow vertical cylinder 21 and several dispersing plates 22 disposed around the periphery of the vertical cylinder 21 and connected to the interior of the vertical cylinder 21. The dispersing plates 22 serve to separate the plastic particles. The top of the vertical cylinder 21 passes through the housing cover 11 and is connected to a hot air pipe 211 for introducing hot air. The hot air pipe 211 introduces hot air into the housing 1 to heat the plastic particles. The dispersing plates 22 separate the plastic particles, making the particle distribution more uniform and increasing the contact area with hot air, thereby achieving uniform heating of the plastic particles and reducing the occurrence of agglomeration. The dispersing plates 22 are hollow plate-shaped structures, and the outer surface of the dispersing plates 22 is a mesh plate, which can increase the contact area between hot air and plastic particles while preventing larger particles or agglomerated materials from entering the dispersing plates 22.

[0043] like Figure 1 and Figure 3As shown, specifically, a material dispersing mechanism 4 for dispersing plastic granules is provided at the bottom of the box body 1. The material dispersing mechanism 4 includes a baffle 41 fixed in the material conveying mechanism 3, a stirring shaft 42 extending into the box body 1, and a motor 43 for driving the stirring shaft 42 to rotate.

[0044] like Figure 3 and 4 - Figure 6 As shown, further, the baffle 41 is fixed inside the sleeve 31, and the bottom end of the baffle 41 is provided with a base plate 411. The base plate 411 has several grooves 412, which allow the broken plastic particles to fall smoothly into the conveying mechanism 3. The top end of the base plate 411 is provided with a conical guide cone 413. The conical structure of the guide cone 413 helps to guide the material to concentrate in the grooves 412, making the material flow smoother and preventing the material from accumulating inside the baffle 41.

[0045] like Figures 4-7 As shown, the stirring shaft 42 extends longitudinally through the base plate 411, and the guide cone 413 passes through it. The stirring shaft 42 is rotatably connected to the base plate 411. Several stirring rods 423 are provided around the periphery of the stirring shaft 42. An end sleeve 422 is fitted and fixed to the top of the stirring shaft 42, and the stirring rods 423 are fixedly connected to the end sleeve 422, so that the stirring shaft 42 can drive the stirring rods 423 to rotate when it rotates. A driven bevel gear 421 is coaxially connected to the bottom end of the stirring shaft 42, and a driving bevel gear 431 is coaxially connected to the end of the output shaft of the motor 43. The driving bevel gear 431 meshes with the driven bevel gear 421. When the motor 43 is working, it drives the driving bevel gear 431 to rotate. Under the action of bevel gear transmission, the driving bevel gear 431 drives the driven bevel gear 421 to rotate, thereby causing the stirring shaft 42 to drive the stirring rods 423 to stir and disperse the plastic particles, preventing the plastic particles from clumping.

[0046] like Figure 7 As shown, it is worth noting that several shovels 424 are fixed on the stirring rod 423. The shovels 424 increase the contact area and force between the stirring rod 423 and the plastic particles. During the stirring process, the shovels 424 can more forcefully scoop up and turn the plastic particles, further improving the dispersing effect, effectively breaking up larger clumps, and making the plastic particles achieve a more uniform dispersion state.

[0047] like Figure 5 As shown, it is worth noting that the bottom end of the base plate 411 is provided with a partition 44, which covers the driven bevel gear 421 and the driving bevel gear 431. The partition 44 protects the driven bevel gear 421 and the driving bevel gear 431, preventing impurities such as plastic particles from entering the gear transmission parts and avoiding gear wear, jamming and other malfunctions.

[0048] It is worth noting that the motor 43 involved in this utility model is a conventional technology and will not be described in detail here.

[0049] In this embodiment, when the auxiliary injection molding box for the injection molding machine is in use, firstly, plastic granules enter the box body 1 from the box cover 11, and are separated by the dispersion plate 22 in the material separation structure 2. At this time, the vertical cylinder 21 introduces hot air through the hot air pipe 211, so that the plastic granules are fully in contact with the hot air in a dispersed state for uniform heating, reducing the agglomeration of the plastic granules. Then, as the material dispersing mechanism 4 starts to work, the motor 43 drives the driving bevel gear 431 to rotate, so that the driving bevel gear 431 interacts with the driven bevel gear 421. The meshing drives the stirring shaft 42 to rotate; finally, the stirring rod 423 and the shovel plate 424 on the stirring shaft 42 stir and disperse the plastic particles, break up the clumps, and make them uniformly dispersed. During the stirring process, the auger 32 in the sleeve 31 rotates in the conveying pipe 311 and steadily conveys the plastic particles to the subsequent injection molding equipment in a spiral pushing manner, so that the dispersed plastic particles are continuously guided by the guide cone 413 to the trough 412 of the bottom plate 411 and fall into the conveying mechanism 3 for conveying.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
