Description

Technical Field

[0001] This utility model relates to the field of filling and molding technology for washing machine counterweights, and in particular to a filling and molding device for washing machine counterweights. Background Technology

[0002] Many washing machines are equipped with counterweights to increase the overall inertia of the machine's movement and reduce vibration during operation. Currently, counterweights are generally made of high-density cement. The raw materials are first mixed using a mixer, and then poured into molds to form counterweights of the required shape and size.

[0003] Existing filling and molding equipment has the following shortcomings in use:

[0004] Existing filling and molding equipment first clamps and fixes the mold on the equipment before filling. However, different washing machine molds have different mold inlet positions, making it impossible to ensure that the inlet of the clamped mold is aligned with the filling port of the filling equipment, which makes it inconvenient to fill different counterweight molds. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that existing filling and molding equipment requires clamping and fixing the mold on the equipment before filling. However, different washing machine molds have different mold inlet positions, making it impossible to ensure that the inlet of the clamped mold is aligned with the filling port of the filling equipment, which makes it inconvenient to fill different counterweight molds. Therefore, this utility model proposes a filling and molding equipment for washing machine counterweights.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A filling and molding device for a washing machine counterweight includes a U-shaped support frame, a concave plate welded to the top of the support frame, a T-shaped fixing plate slidably connected to the inner wall of the concave plate, a placement plate for placing a counterweight mold on the top of the fixing plate, and a clamping mechanism for clamping and fixing the mold on the placement plate.

[0008] The concave plate has supports welded to both sides, and the same sleeve plate is welded to the side of the two supports that are close to each other. The sleeve plate has a round hole, and a filling box is welded to the inner wall of the round hole. The bottom of the filling box is conical, and a filling pipe is fixedly installed at the bottom of the filling box and connected to it. A valve is installed at the bottom of the filling pipe. The top of the filling box has a feed port and a cover is installed by a hinge. The filling box is equipped with a conveying mechanism for conveying cement material downward.

[0009] The fixed plate is equipped with an adjustment mechanism for moving the clamping mechanism left, right, forward, and backward so that the mold inlet can be aligned with the filling tube.

[0010] In one possible design, the clamping mechanism includes a first clamping plate, a second clamping plate, a short plate, and a first threaded rod. The bottom of the first clamping plate is fixedly connected to one side of the top of the placement plate, the bottom of the second clamping plate is slidably connected to the top of the placement plate, the bottom of the short plate is fixedly connected to the other side of the top of the placement plate, a first nut is embedded in one side of the short plate, the first threaded rod is threadedly connected to the first nut, and one end of the first threaded rod is rotatably connected to one side of the second clamping plate. A knob for easy rotation is fixedly provided at one end of the first threaded rod.

[0011] In one possible design, the adjustment mechanism includes a first movable plate, a third motor for driving the placement plate to move back and forth, and a second motor for driving the placement plate to move left and right. The top of the fixed plate has a first groove, and the inner walls of both sides of the first groove are rotatably connected to the same third lead screw. One side of the third motor is fixedly connected to one side of the fixed plate, and its output end passes through one side of the fixed plate and is fixedly connected to one end of the third lead screw. A first slider is slidably connected to the inner wall of the first groove, and a third lead screw nut is embedded in one side of the first slider. The third lead screw nut is threadedly connected to the third lead screw. The bottom of the first movable plate is slidably connected to the top of the fixed plate, and the top of the first slider is fixedly connected to the bottom of the first movable plate.

[0012] The top of the first movable plate is provided with a second groove, and the inner walls of both sides of the second groove are rotatably connected to the same second lead screw. One side of the second motor is fixedly connected to one side of the first movable plate, and the output end passes through one side of the first movable plate and is fixedly connected to one end of the second lead screw. The inner wall of the second groove is slidably connected to a second slider, and one side of the second slider is embedded with a second lead screw nut. The second lead screw nut is threadedly connected to the second lead screw. The top of the second slider is fixedly connected to the bottom of the placement plate.

[0013] In one possible design, the conveying mechanism includes a first motor, a rotating rod, and a spiral conveying blade. The bottom of the first motor is fixedly connected to the top of the filling tank, the top of the rotating rod is rotatably connected to the inner wall of the top of the filling tank, the output end of the first motor passes through the top of the filling tank and is fixedly connected to the top of the rotating rod, the bottom end of the rotating rod is located inside the filling tube, the spiral conveying blade is welded to the rotating rod, and a stirring blade for preventing sedimentation is welded to the rotating rod.

[0014] In one possible design, the bottom inner wall of the support frame is fixedly provided with a driving component that facilitates adjusting the distance between the placement plate and the filling tube according to the mold size. The telescopic part of the driving component passes through the bottom of the concave plate and is fixedly connected to the bottom of the fixed plate.

[0015] In one possible design, a groove is provided on one side of the placement plate to improve the stability of the movement of the second clamping plate, and a U-shaped plate is fixedly provided on one side of the second clamping plate, with one end of the U-shaped plate slidably connected to the inner wall of the groove.

[0016] In this application, during use, the distance between the placement plate and the filling tube is adjusted by the drive component according to the size of the counterweight mold to be filled. The telescopic part of the drive component pushes the fixed plate to slide within the concave plate, thereby adjusting the height of the placement plate. The counterweight mold is placed on the placement plate (located between the first and second clamping plates), and the mold is fixed using a clamping mechanism. Rotating the knob drives the first threaded rod to rotate. Since the first threaded rod is threadedly connected to the first nut on the short plate, the first threaded rod pushes the second clamping plate closer to the first clamping plate, thereby clamping the mold. Then, the position of the mold inlet is adjusted according to the position of the filling tube. The third motor is started, driving the third lead screw to rotate. Since the first slider is connected to the nut of the third lead screw, the first slider drives the first moving plate to move back and forth on the fixed plate. The second motor is started, driving the second lead screw to rotate. Since the second slider is connected to the nut of the second lead screw, the second slider drives the placement plate to move left and right on the first moving plate. Through the cooperation of the third and second motors, the position of the mold can be precisely adjusted. Align the mold's inlet with the filling pipe to adjust its position, ensuring the inlet of the clamped mold is directly opposite the filling port of the filling equipment. This facilitates filling different counterweight molds. Open the cover and pour cement or other counterweight materials into the filling tank. Then, open the valve and start the first motor. The first motor drives the rotating rod to rotate, and the spiral conveying blades on the rotating rod push the material downwards and pour it into the mold through the filling pipe. The stirring blades prevent material from settling in the filling tank. Once the mold is full, close the valve to stop filling. After filling, release the clamps on the mold and remove it. Note that the first, second, and third motors, as well as the drive components (which can be electric push rods, hydraulic cylinders, or pneumatic cylinders), require an external controller and external power supply. The first, third, and second motors can be stepper motors, which can rotate in both directions. The material, type, and size of the first, third, and second threaded rods can be selected according to actual needs.

[0017] In this utility model, the filling and molding equipment for a washing machine counterweight block, through an adjustment mechanism, starts a third motor to drive a third lead screw to rotate. Since the first slider is connected to the third lead screw nut, the first slider will drive the first moving plate to move back and forth on the fixed plate. Start a second motor to drive a second lead screw to rotate. Since the second slider is connected to the second lead screw nut, the second slider will drive the placement plate to move left and right on the first moving plate. Through the cooperation of the third motor and the second motor, the position of the mold can be precisely adjusted so that the inlet of the mold is aligned with the filling tube. Thus, the position of the mold can be adjusted so that the inlet of the clamped mold is directly opposite the filling port of the filling equipment, so as to facilitate the filling of different counterweight block molds.

[0018] In this utility model, the filling and molding equipment for a washing machine counterweight block uses a clamping mechanism to rotate a knob, which drives the first threaded rod to rotate. Since the first threaded rod is threadedly connected to the first nut on the short plate, the first threaded rod will push the second clamping plate closer to the first clamping plate, thereby clamping the mold.

[0019] In this invention, the position of the mold (front, back, left, and right) can be adjusted by the adjustment mechanism so that the feed port of the clamped mold is aligned with the filling port of the filling equipment, so as to facilitate filling of different counterweight molds. The clamping mechanism can clamp the mold tightly to prevent shaking. Attached Figure Description
