Description

Technical Field

[0001] The utility model relates to the technical field of casting, and more specifically, to a novel wax slurry adjusting machine. Background Art

[0002] Wax mold is a commonly used casting method. Wax mold is used to form the shape of the casting cavity. To obtain castings with high dimensional accuracy and surface finish, the wax mold itself should first have high dimensional accuracy and surface finish. Therefore, the production of wax mold requires the use of a wax slurry mixing machine to ensure that the mold material is fully mixed to form a qualified wax slurry.

[0003] However, the existing wax slurry mixing machine is usually simple in structure, and various raw materials are mixed and stirred by a single stirring shaft. However, in order to fully mix the raw materials, such a structure with a relatively simple stirring form increases the stirring time, which affects the wax slurry preparation efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a novel wax slurry mixing machine, which solves the problem of low wax slurry mixing efficiency in the prior art.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a new wax slurry mixing machine, including a shell, a partition is horizontally arranged in the shell, and the shell is located on both sides of the partition respectively. A first chamber and a second chamber, a plurality of slide grooves are opened on the partition, and the plurality of slide grooves are distributed in a circular array with the center of the partition as the center, and sliders are slidably connected in the plurality of slide grooves, and a driving mechanism for driving the slider to slide is arranged in the first chamber, and the bottom of the slider is located in the second chamber and is provided with a mounting shell, and a first motor is arranged in the mounting shell, and the output shaft of the first motor passes through the mounting shell and is transmission-connected to a stirring shaft, and a plurality of stirring rods are arranged on the stirring shaft, and an inlet is opened on the side wall of the second chamber, and a discharge port is opened at the bottom of the second chamber.

[0006] By adopting the above technical solution, in order to improve the stirring efficiency, when in use, the worker first adds each material into the second chamber through the feed port, starts the first motor, and driven by the first motor, the stirring shaft will drive multiple stirring rods to stir the materials. At the same time, the driving mechanism drives the slider to slide back and forth along the slide groove, so that the multiple stirring shafts can stir while radially displacing, thereby expanding the stirring area, allowing the stirring rods to better contact the materials, and allowing the materials to form a more complex vortex in the second chamber, increasing the impact mixing between the materials, helping to reduce the stirring time, and improving the uniformity of the wax slurry.

[0007] The utility model is further configured as follows: the stirring rods on two adjacent stirring shafts are mutually staggered in the axial direction, and the two adjacent stirring shafts rotate in opposite directions.

[0008] By adopting the above technical solution, the stirring rods are staggered with each other, so that the stirring rods can be radially displaced to a greater extent without colliding with each other, and the opposite stirring shafts can drive the materials to form swirls in different directions, effectively forming convection in the second chamber, cross-mixing each other, and further improving the mixing effect.

[0009] The utility model is further configured as follows: the driving mechanism includes a transmission plate rotatably connected to the partition, and a number of regularly distributed connecting rods are rotatably connected to the transmission plate, the number of the connecting rods is consistent with the number of sliders, and the other ends of the connecting rods are respectively rotatably connected to the corresponding sliders, and a driving mechanism for driving the transmission plate to intermittently reciprocate is arranged in the first chamber.

[0010] By adopting the above technical solution, the transmission disk can push or pull the slider to slide back and forth through the connecting rod during the reciprocating rotation, and when the slider changes direction, there is a certain pause time, which can ensure the smooth movement of the stirring shaft and the stirring rod. On the other hand, the rotation of the transmission disk can make multiple sliders slide at the same time, which can be achieved with a single driving force, saving costs.

[0011] The utility model is further configured as follows: the driving mechanism includes a groove wheel fixed concentrically with the transmission disk, the groove wheel is provided with two radial grooves, two oppositely rotating shifting rods are symmetrically arranged on both sides of the groove wheel, the shifting rods are provided with shifting pins, and the two shifting pins are respectively alternately matched with the two radial grooves to shift the groove wheel for intermittent reciprocating rotation.

[0012] The utility model is further configured as follows: the driving mechanism also includes a first gear concentrically fixed on the shifting rod, two second gears meshing in sequence are arranged between the two first gears, a second motor is arranged on the inner wall of the first chamber, and the output shaft of the second motor is transmission-connected to one of the first gears.

[0013] The utility model is further configured as follows: a concave locking arc is provided on the outer peripheral surface of the groove wheel, and a convex locking arc is coaxially fixed on the lever and is positioned and matched with the concave locking arc.

[0014] The utility model is further configured as follows: the cross section of the slide groove is a T-shaped structure, and the cross section of the slide block is an adapted "I"-shaped structure.

[0015] The utility model is further configured as follows: a plurality of mounting grooves are provided on the upper end surface of the slide groove, balls are embedded in the plurality of mounting grooves, and the slider is in rolling contact with the slide groove through the balls.

[0016] In summary, the utility model has the following beneficial effects:

[0017] 1. The driving mechanism is set to drive the slider to slide back and forth along the slide groove, so that multiple stirring shafts can move radially while stirring, expanding the stirring area, making the stirring rod better contact with the material, so that the material forms a more complex swirl in the second chamber, increasing the impact mixing between the materials, helping to reduce the stirring time and improve the uniformity of the wax slurry;

[0018] 2. Through the driving mechanism set up, the transmission disc can push or pull the slider to slide back and forth through the connecting rod during the reciprocating rotation, and when the slider changes direction, there is a certain pause time, which can ensure the smooth movement of the stirring shaft and stirring rod. On the other hand, the rotation of the transmission disc can make multiple sliders slide at the same time, which can be achieved with only a single driving force, saving costs.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] The utility model is described in detail below in conjunction with the accompanying drawings.

[0028] Reference Figure 1-Figure 4 A novel wax slurry mixing machine comprises a shell 1, a partition 2 is horizontally fixed in the shell 1, a first chamber 3 and a second chamber 4 are located on both sides of the partition 2 in the shell 1, a plurality of chutes 5 are provided on the partition 2, the plurality of chutes 5 are distributed in a circular array with the center of the partition 2 as the center, a slider 6 is slidably connected in the plurality of chutes 5, and a driving mechanism 7 for driving the slider 6 to slide is provided in the first chamber 3;

[0029] The driving mechanism 7 includes a transmission disk 701 rotatably connected to the partition 2, and a number of regularly distributed connecting rods 702 are rotatably connected to the transmission disk 701. The number of the connecting rods 702 is consistent with the number of the sliders 6, and the other ends of the connecting rods 702 are rotatably connected to the corresponding sliders 6. A driving mechanism 703 for driving the transmission disk 701 to intermittently reciprocate is provided in the first chamber 3. During the reciprocating rotation of the transmission disk 701, the connecting rod 702 can push or pull the slider 6 to slide back and forth, and when the slider 6 changes direction, it has a certain rest time, which can ensure the smooth movement of the stirring shaft 8 and the stirring rod 9. On the other hand, the rotation of the transmission disk 701 can make multiple sliders 6 slide at the same time, which can be achieved with only a single driving force, saving costs.

[0030] The driving mechanism 703 includes a groove wheel 7031 fixed concentrically with the transmission disk 701, and two radial grooves 7032 are provided on the groove wheel 7031. Two counter-rotating levers 7033 are symmetrically arranged on both sides of the groove wheel 7031. The lever 7033 is fixed with a driving pin 7034, and the driving pin 7034 is installed on a mounting frame fixed on the partition 2. The two driving pins 7034 are alternately matched with the two radial grooves 7032 to drive the groove wheel 7031 to intermittently reciprocate.

[0031] The driving mechanism 703 also includes a first gear 7035 concentrically fixed on the lever 7033, two second gears 7036 meshing in sequence are arranged between the two first gears 7035, a second motor is fixed on the inner wall of the first chamber 3, the output shaft of the second motor is connected to one of the first gears 7035, the second motor drives the first gear 7035 to rotate, the first gear 7035 is meshed in sequence through the two second gears 7036, and then drives the other first gear 7035 to rotate in the opposite direction, thereby driving the two lever pins 7034 to rotate in the opposite direction.

[0032] A concave locking arc 7037 is provided on the outer circumferential surface of the groove wheel 7031 , and a convex locking arc 7038 is coaxially fixed on the lever 7033 and is positioned and matched with the concave locking arc 7037 .

[0033] For the convenience of description, the two radial grooves 7032 are named radial groove a and radial groove b respectively, and the two detent pins 7034 are named detent pin a and detent pin b respectively. When detent pin a rotates into radial groove a, it starts to drive the groove wheel 7031 to rotate until the detent pin a rotates out of radial groove a. At this time, the groove wheel 7031 is driven to rotate 90 degrees, that is, the radial groove b also rotates forward 90 degrees, which just allows the detent pin b to rotate in and drive the groove wheel 7031 to rotate 90 degrees in the opposite direction. The radial groove a can be driven by the detent pin a again, and the cycle is repeated to realize the intermittent reciprocating rotation of the groove wheel 7031, and then the intermittent reciprocating rotation of the transmission plate 701.

[0034] When the push pin a rotates out of the radial groove a and the push pin b rotates into the radial groove b, the convex locking arc 7038 fixed concentrically with the push pin a conflicts with the concave locking arc 7037 for positioning, preventing the groove wheel 7031 from rotating by itself due to inertia during this process, resulting in the push pin b being unable to rotate into the radial groove b. Similarly, when the push pin b rotates out of the radial groove b and the push pin a rotates into the radial groove a, the convex locking arc 7038 fixed concentrically with the push pin b conflicts with the concave locking arc 7037 for positioning.

[0035] The cross section of the slide 5 is a T-shaped structure, the cross section of the slider 6 is an adapted "I"-shaped structure, and a plurality of mounting grooves are provided on the upper end surface of the slide 5, and balls 10 are embedded in the plurality of mounting grooves. The slider 6 is in rolling contact with the slide 5 through the balls 10. Since the motor, the stirring shaft 8 and the stirring rod 9 are all arranged at the bottom of the slider 6, the slider 6 is subjected to a large downward pulling force. At this time, the balls 10 are arranged to make the slider 6 in rolling contact with the slide 5, thereby greatly reducing the movement resistance.

[0036] The bottom of the slider 6 is located in the second chamber 4 and is fixedly provided with a mounting shell (not shown in the figure), in which a first motor is fixedly provided, and an output shaft of the first motor penetrates the mounting shell and is drivingly connected to a stirring shaft 8, on which a plurality of stirring rods 9 are provided;

[0037] The stirring rods 9 on two adjacent stirring shafts 8 are axially offset from each other, and the two adjacent stirring shafts 8 rotate in opposite directions. The stirring rods 9 are offset from each other, so that the stirring rods 9 can be radially displaced to a greater extent without colliding with each other, and the opposite stirring shafts 8 can drive the material to form swirls in different directions, effectively forming convection in the second chamber 4, cross-mixing each other, and further improving the mixing effect.

[0038] A material inlet is provided on the side wall of the second chamber 4 , and a material outlet is provided at the bottom of the second chamber 4 .

[0039] Working principle: In order to improve the stirring efficiency, when in use, the worker first adds the materials into the second chamber 4 through the feeding port, starts the first motor, and driven by the first motor, the stirring shaft 8 will drive multiple stirring rods 9 to stir the materials. At the same time, the driving mechanism 7 drives the slider 6 to slide back and forth along the slide 5, so that the multiple stirring shafts 8 can stir while radially displacing, expanding the stirring area, allowing the stirring rod 9 to better contact with the material, and allowing the material to form a more complex vortex in the second chamber 4, increasing the impact mixing between the materials, helping to reduce the stirring time, and improve the uniformity of the wax slurry. The evenly mixed wax slurry is discharged from the discharge port.

[0040] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
