[0001] This utility model relates to the field of injection molding equipment technology, specifically to an injection molding particle material mixing platform. Background Technology

[0002] In the injection molding process of automotive interior parts, it is often necessary to mix plastic particles of different colors and types, or with added color masterbatch or functional masterbatch, in order to achieve specific product colors or performance. Currently, the common mixing method mainly relies on simple electric mixers.

[0003] For example, Chinese patent application number CN202322325922.7 discloses a novel plastic particle mixer, including a mixing chamber comprising a feeding chamber and a mixing chamber. A guide baffle is provided between the feeding chamber and the mixing chamber. The feeding chamber contains a feeding and mixing assembly, which includes a feeding motor fixed to the guide baffle, a feeding shaft fixed to the feeding motor, and multiple staggered mixing rods fixed to the feeding shaft. This design is intended to improve the thoroughness of plastic particle mixing. However, the mixing rods are fixed. During mixing, when the material bulk density or resistance changes, the fixed mixing rods are prone to excessive lateral force and jamming, resulting in poor mixing effect or even dead zones in the mixing process. Summary of the Invention

[0004] The purpose of this utility model is to provide a mixing platform for injection molding particles to solve the technical problem that in the prior art, the mixing rod is fixed in a fixed manner. During the mixing process, when the material bulk density or resistance changes, the fixed mixing rod is easily subjected to excessive lateral force and becomes stuck, resulting in poor mixing effect or even the formation of mixing dead zones.

[0005] A mixing platform for injection molding particles includes a base frame and a fixed seat on top of the base frame. A lifting plate is mounted on the fixed seat via a drive unit. The lifting plate corresponds to a particle receiving tank placed at the bottom of the base frame. A cross mounting frame is provided on the lifting plate. A longitudinal stirring rod is provided at the end of the cross mounting frame. A plurality of transverse stirring rods are evenly distributed on the longitudinal stirring rod.

The cylinder is vertically mounted on the fixed base, the output end of the cylinder is connected to the lifting plate, the guide rod is connected to the lifting plate, and the guide rod is also slidably disposed on the fixed base.

[0007] Preferably, there are two guide rods, both of which are parallel to the output shaft of the cylinder.

[0008] Preferably, the second drive unit includes a drive motor, a drive wheel, and a gear ring. The drive motor is mounted on the lifting plate, the drive wheel is located on the output end of the drive motor, and a driven wheel is rotatably mounted on the lifting plate. The driven wheel is connected to the drive wheel via a synchronous belt. The cross mounting bracket is coaxially fixed on the driven wheel, the gear ring is fixed on the lifting plate, and a gear is provided on the longitudinal stirring rod, which meshes with the gear ring.

[0009] Preferably, a top rod is slidably provided inside the cross mounting bracket, and a spring is also provided inside the cross mounting bracket, with the spring abutting against the end of the top rod.

[0010] Preferably, the transverse stirring rods are adjustablely mounted on the longitudinal stirring rods via fastening bolts.

[0011] Preferably, the transverse stirring rods on two adjacent longitudinal stirring rods are staggered.

[0012] The advantages of this utility model are as follows: by setting up a liftable lifting plate, and cooperating with a cross mounting frame equipped with longitudinal stirring rods and transverse stirring rods, under the joint drive of the first drive unit, the longitudinal stirring rod at the end of the cross mounting frame revolves and rotates synchronously in the container, thereby driving the transverse stirring rod to rotate.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1 to 4 As shown, an injection molding particle mixing platform includes a base frame 1 and a fixed seat 2 located on the top of the base frame 1. A lifting plate 3 is provided on the fixed seat 2 via a drive unit 1. The lifting plate 3 corresponds to a particle receiving tank located at the bottom of the base frame 1. A cross mounting frame 4 is provided on the lifting plate 3. A longitudinal stirring rod 5 is provided at the end of the cross mounting frame 4. Several transverse stirring rods 6 are evenly distributed on the longitudinal stirring rod 5. A drive unit 2 is provided on the lifting plate 3 to drive the cross mounting frame 4 to rotate.

[0020] In this embodiment, the drive unit includes a cylinder 7 and a guide rod 8. The cylinder 7 is vertically mounted on the fixed base 2, and the output end of the cylinder 7 is connected to the lifting plate 3. The guide rod 8 is connected to the lifting plate 3 and is also slidably mounted on the fixed base 2.

[0021] In this embodiment, there are two guide rods 8, both of which are parallel to the output shaft of the cylinder 7, ensuring consistency in the direction of movement, reducing unnecessary friction and wear, and making the lifting action smoother and more reliable.

[0022] In this embodiment, the second drive unit includes a drive motor 9, a drive wheel 10, and a gear ring 11. The drive motor 9 is mounted on the lifting plate 3, the drive wheel 10 is located on the output end of the drive motor 9, and a driven wheel 12 is rotatably mounted on the lifting plate 3. The driven wheel 12 is connected to the drive wheel 10 through a synchronous belt 13. The cross mounting bracket 4 is coaxially fixed on the driven wheel 12, and the gear ring 11 is fixed on the lifting plate 3. A gear 14 is provided on the longitudinal stirring rod 5, and the gear 14 meshes with the gear ring 11.

[0023] In this embodiment, a push rod 15 is slidably provided inside the cross mounting bracket 4, and a spring 16 is also provided inside the cross mounting bracket 4. The spring 16 abuts against the end of the push rod 15. The elastic preload provided by the spring 16 can ensure that the gear 14 and the gear ring 11 always maintain a good meshing state, eliminating the shaking and noise that may be caused by manufacturing gaps.

[0024] In this embodiment, the transverse stirring rods 6 are all adjustablely mounted on the longitudinal stirring rods 5 by fastening bolts. The height distribution, extension length or tilt angle of the transverse stirring rods 6 on the longitudinal stirring rods 5 can be flexibly adjusted according to the characteristics of the material being stirred and the desired mixing intensity, making it highly adaptable.

[0025] In this embodiment, the transverse stirring rods 6 on the two adjacent longitudinal stirring rods 5 are staggered, which effectively disrupts the flow pattern of the material and forces the material to generate more complex cross convection and mutual penetration in the radial, circumferential and axial directions. This significantly reduces the mixing dead angles, accelerates the mixing process, and thus achieves higher mixing uniformity in a shorter time, improving stirring efficiency and quality.

[0026] Working process and principle: In this embodiment, the container holding the mixed plastic particles is first placed at the bottom of the base frame 1, directly below the lifting plate 3. The lifting plate 3 is lowered by the output end of the cylinder 7, so that the longitudinal stirring rod 5 and the transverse stirring rod 6 are immersed in the material to a suitable depth. Subsequently, the output of the drive motor 9 drives the drive wheel 10 to rotate, which in turn drives the cross mounting frame 4 to rotate via the synchronous belt 13 and the driven wheel 12. This allows the longitudinal stirring rods 5 at the ends of the cross mounting frame 4 to revolve within the container. Simultaneously, under the action of the gear ring 11, the corresponding longitudinal stirring rods 5 are driven to rotate synchronously via the gears 14 on each longitudinal stirring rod 5. This, in turn, drives the transverse stirring rods 6 to rotate. Under the combined action of the revolution, rotation, and the staggered transverse stirring rods 6, the material is fully stirred and rapidly mixed. After the stirring is completed, the output of the cylinder 7 drives the lifting plate 3 to rise, allowing the container of mixed plastic particles to be removed.

[0027] Based on the above, this utility model, by setting up a liftable lifting plate 3, and cooperating with a cross mounting frame 4 equipped with a longitudinal stirring rod 5 and a transverse stirring rod 6, under the joint drive of the first drive unit, enables the longitudinal stirring rod 5 at the end of the cross mounting frame 4 to revolve around the container and rotate synchronously on its own axis, thereby driving the transverse stirring rod 6 to rotate. Under the combined action of the revolution, rotation, and the staggered transverse stirring rod 6, the material is fully stirred and quickly mixed, avoiding the occurrence of stirring dead zones.

[0028] As is known from common technical knowledge, this utility model can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
