Technical Field

[0001] The utility model belongs to the technical field of the production of plastic fittings for household appliances, and relates to a compression molding device, in particular to a compression molding device for highly durable plastic fittings for household appliances. Background Art

[0002] Highly durable plastic fittings for household appliances refer to plastic parts used in household appliances, which have excellent mechanical properties, wear resistance, aging resistance, chemical corrosion resistance and other characteristics, and can maintain a good service state for a long time. These fittings are usually used in key parts of household appliances, such as motor brackets, gears, bearing brackets, shells, etc., and have an important impact on the overall performance and service life of household appliances. The production methods of highly durable plastic fittings for household appliances mainly include molding processes such as injection molding, extrusion, and compression molding.

[0003] The compression molding device for highly durable plastic fittings for household appliances is a mechanical device specifically used for processing and manufacturing highly durable plastic fittings. This device presses plastic raw materials into fittings with specific shapes, sizes and performance requirements through the action of high pressure and heat to meet the needs of the household appliance industry for high-quality and highly durable plastic fittings.

[0004] The existing compression molding devices for highly durable plastic fittings for household appliances have problems such as low production efficiency, inability to achieve continuous operation, low production quality, and inability to adapt to different plastic fittings for household appliances.

[0005] Based on this, we propose a compression molding device for highly durable plastic fittings for household appliances, which has high production efficiency, can realize continuous operations of spraying mold release agent, injecting material, compression molding and ejecting, and has high production quality, and can adapt to different plastic fittings for household appliances. Summary of the Utility Model

[0006] The purpose of the utility model is to address the above problems in the existing technology and propose a compression molding device for highly durable plastic fittings for household appliances. The technical problem to be solved by this utility model is: how to achieve continuous operations of spraying mold release agent, injecting material, compression molding and ejecting for highly durable plastic fittings for household appliances with high quality and high efficiency, and can adapt to different plastic fittings for household appliances.

[0007] The purpose of the utility model can be achieved by the following technical solutions:

[0008] A compression molding device for a highly durable plastic fitting of household appliances, comprising a main rotation mechanism and a hydraulic pushing mechanism. The main rotation mechanism includes a bottom plate, on which a support column is fixed. A rotating column is rotatably provided on the support column, and a top plate is fixed on the support column. The hydraulic pushing mechanism is arranged on the bottom plate. Lower mold mechanisms are rotatably provided on four end faces of the rotating column. An injection mechanism, a lifting spray mechanism, a flipping and discharging mechanism, and a compression molding mechanism are sequentially arranged on the lower side of the top plate. Among them, the compression molding mechanism is directly opposite to the hydraulic pushing mechanism; the injection mechanism is connected to an injection barrel, and the lifting spray mechanism and the compression molding mechanism are connected to a mold release agent storage tank.

[0009] The working principle of the present utility model is: select a suitable lower mold body, injection part, and upper mold according to the shape production requirements of the plastic fitting of household appliances;

[0010] The motor drives the driving wheel to rotate, thereby driving the driven wheel to rotate 90°, thereby driving the rotating column to rotate 90°, and rotating the position of the first lower mold mechanism to directly below the lifting spray mechanism. The hydraulic component 1 adjusts the vertical distance between the spray component 1 and the lower mold body, and the spray component 1 sprays the mold release agent on the inner surface of the lower mold body. This is the mold release agent spraying action;

[0011] After completion, the main rotation mechanism drives the lower mold mechanism to rotate to directly below the injection mechanism. The transverse movement screw rod component adjusts the front and rear positions of the injection part, and the longitudinal movement screw rod component adjusts the left and right positions of the injection part, so that the injection part can inject the compression molding raw material evenly at a suitable position. The injection part is used to inject the compression molding raw material into the lower mold body. This is the injection action. At this time, the second lower mold mechanism is directly opposite to the lifting spray mechanism, and the lifting spray mechanism repeats the mold release agent spraying action on the second lower mold mechanism;

[0012] After completion, the main rotation mechanism continues to drive the first lower mold mechanism to rotate to directly below the compression molding mechanism. The hydraulic component 3 pushes the force receiving plate upward until it abuts against the lower mold plate. The hydraulic component 2 pushes the upper mold to tightly abut against the lower mold plate for compression molding. After molding, the hydraulic component 2 drives the upper mold to rise and reset. The electric push rod is pushed out, and the push plate is pushed upward, thereby driving the push rod to eject the lower mold body. This is the compression molding action, so that the plastic fitting of household appliances formed in the lower mold body does not adhere to the inner surface of the lower mold body;

[0013] At this time, the lifting spray mechanism continues to repeat the mold release agent spraying action on the third lower mold mechanism, and the injection mechanism continues to repeat the injection action on the second lower mold mechanism, and so on;

[0014] After completion, the rotating column drives the lower die mechanism to rotate to directly below the flipping and discharging mechanism, causing the insertion block to be inserted into the insertion slot block. The cam rotating part drives the insertion slot block to flip 180°, thereby driving the insertion block to rotate 180°, driving the entire lower die mechanism to rotate 180°, causing the household appliance plastic fittings formed within the lower die body to fall off onto the conveyor belt. After completion, the rotating part drives the insertion slot block to flip back to its original position again, thereby driving the insertion block to rotate 180°, causing the entire lower die mechanism to return to its original position. The flipping and discharging mechanism flips the lower die mechanism, causing the household appliance plastic fittings within the lower die mechanism to fall onto the conveyor belt. The flipping and discharging mechanism flips the lower die mechanism again to reset the lower die mechanism. This is the discharging action;

[0015] After completion, the main rotating mechanism drives the first lower die mechanism to rotate to directly below the lifting and spraying mechanism, and the lifting and spraying mechanism repeats the demoulding agent spraying action on this lower die mechanism, and so on.

[0016] The main rotating mechanism includes a motor, a driven wheel, and a driving wheel. The driven wheel and the driving wheel mesh with each other. The motor is fixed inside the bottom plate, the output shaft of the motor is fixedly connected to the driving wheel, the driven wheel is fixed at the bottom of the rotating column, and the driven wheel is rotatably arranged on the support column.

[0017] With the above structure, the output shaft of the motor drives the driving wheel to rotate intermittently, and the interval time is the time of the action with the longest duration among them, thereby driving the driven wheel to rotate 90°, thereby driving the rotating column to rotate 90°, thereby driving the four lower die mechanisms to rotate to the designated positions.

[0018] The lower die mechanism includes a lower die plate. The lower die plate is rotatably arranged on the end surface of the corresponding position of the rotating column. A detachable lower die body is provided inside the lower die plate. A push plate is slidably provided at the bottom of the lower die plate. A number of push rods are provided at corresponding positions on the push plate. The push rods penetrate through the lower die plate and the lower die body, and at the initial position, the front ends of the number of push rods are flush with the inner surface of the lower die body. An insertion block is fixed on the outer wall of the lower die plate.

[0019] With the above structure, a suitable lower die body is selected according to the shape production requirements of the household appliance plastic fittings; after the compression molding action, the hydraulic jacking mechanism jacks the push plate upward, thereby jacking the number of push rods out of the lower die body, so that the household appliance plastic fittings formed within the lower die body do not adhere to the inner surface of the lower die body; after completion, the hydraulic jacking mechanism resets, driving the number of push rods to reset, enabling the flipping block to cooperate with the flipping and feeding mechanism to drive the lower die mechanism to rotate 180°, causing the household appliance plastic fittings formed within the lower die body to fall off.

[0020] The injection mechanism includes a transverse translation screw member fixed to the lower side of the top plate. A longitudinal translation screw member is fixed to the sliding block of the transverse translation screw member. A sliding plate is fixed to the sliding block of the longitudinal translation screw member. A detachable injection member is vertically provided on the sliding plate, and the injection member is connected to the injection cylinder.

[0021] With the above structure, a suitable injection member is selected according to the shape production requirements of the household appliance plastic parts, and the installation height of the injection member is adjusted; the transverse translation screw member adjusts the front and back positions of the injection member, and the longitudinal translation screw member adjusts the left and right positions of the injection member, so that the injection member can inject materials evenly at a suitable position. The injection member is used to inject the compression molding raw materials into the lower mold body.

[0022] The lifting and spraying mechanism includes a first hydraulic member fixed to the lower side of the top plate. A first spraying member is fixed to the pushing rod of the first hydraulic member, and the first spraying member is connected to the release agent storage tank.

[0023] With the above structure, the first hydraulic member adjusts the vertical distance between the first spraying member and the lower mold body, and the first spraying member sprays the release agent on the inner surface of the lower mold body.

[0024] The flipping and discharging mechanism includes a cam rotating member fixed to the top plate. The cam rotating member is horizontally arranged, and the axis of the output shaft of the cam rotating member coincides with the axis of rotation of the lower mold plate. An insertion groove block is fixed to the output shaft of the cam rotating member, and the thickness of the insertion groove of the insertion groove block is the same as the height of the insertion block.

[0025] With the above structure, the rotating column drives the lower mold mechanism to rotate to directly below the flipping and discharging mechanism, so that the insertion block is inserted into the insertion groove block. The cam rotating member drives the insertion groove block to flip 180°, thereby driving the insertion block to rotate 180°, driving the entire lower mold mechanism to rotate 180°, so that the household appliance plastic parts formed in the lower mold body fall off. After completion, the rotating member drives the insertion groove block to flip back to its original position again, thereby driving the insertion block to rotate 180°, and resetting the entire lower mold mechanism.

[0026] The compression molding mechanism includes a second hydraulic member and a second spraying member. The second spraying member is connected to the release agent storage tank. The second hydraulic member and the second spraying member are both fixed to the lower side of the top plate. A detachable upper mold is provided on the pushing rod of the second hydraulic member. In the initial position, the upper mold is located above the second spraying member.

[0027] With the above structure, a suitable upper mold is selected according to the shape production requirements of the household appliance plastic parts;

[0028] During the compression molding operation, the second hydraulic member pushes the upper mold to tightly abut against the lower mold plate, forming a closed compression molding space, so that the compression molding raw materials inside the lower mold body are molded. After molding, the second hydraulic member drives the upper mold to rise and reset, and the second spraying member sprays the release agent on the lower side of the upper mold.

[0029] The hydraulic jacking mechanism includes a third hydraulic component, which is fixed on the bottom plate. A force-bearing plate is fixed on the third hydraulic component, and the force-bearing plate is directly opposite to the position of the upper mold. A number of vertically upward electric push rods are provided on the force-bearing plate, and the electric push rods are directly opposite to the position of the push plate.

[0030] With the above structure, during the compression molding operation, the third hydraulic component pushes the force-bearing plate upward until it abuts against the lower mold plate. The second hydraulic component pushes the upper mold tightly against the lower mold plate for the compression molding operation. After molding, the upper mold disengages from the lower mold plate, and the electric push rods are pushed out to push the push plate upward, thereby driving the push rod to eject the lower mold body.

[0031] Compared with the prior art, the compression molding device for high-durability household appliance plastic parts has the following advantages:

[0032] 1. The main rotation mechanism drives the four lower mold mechanisms to rotate to the designated positions, realizing continuous operations such as spraying mold release agent, injecting material, compression molding and ejection, and discharging simultaneously, improving production efficiency;

[0042] The following are specific embodiments of the present utility model and, in conjunction with the accompanying drawings, further describe the technical solutions of the present utility model, but the present utility model is not limited to these embodiments.

[0043] As Figures 1-4 shown, the compression molding device for high-durability household appliance plastic parts includes a main rotating mechanism 1 and a hydraulic pushing mechanism 7. The main rotating mechanism 1 includes a bottom plate 101. A support column 104 is fixed on the bottom plate 101. A rotating column 106 is rotatably provided on the support column 104. A top plate 105 is fixed on the support column 104. The hydraulic pushing mechanism 7 is arranged on the bottom plate 101. Lower mold mechanisms 2 are rotatably provided on four end faces of the rotating column 106. Below the top plate 105, a material injection mechanism 3, a lifting and spraying mechanism 4, a flipping and discharging mechanism 5, and a compression molding mechanism 6 are sequentially provided. Among them, the position of the compression molding mechanism 6 is directly opposite to that of the hydraulic pushing mechanism 7; the material injection mechanism 3 is connected to a material injection cylinder, and the lifting and spraying mechanism 4 and the compression molding mechanism 6 are connected to a mold release agent storage tank.

[0044] In this embodiment, appropriate lower mold mechanisms 2, material injection mechanisms 3, and compression molding mechanisms 6 are selected according to the shape production requirements of the household appliance plastic parts;

[0045] The main rotating mechanism 1 rotates the position of the first lower mold mechanism 2 to directly below the lifting and spraying mechanism 4, and the lifting and spraying mechanism 4 sprays the mold release agent onto the lower mold mechanism 2. This is the mold release agent spraying action;

[0046] After completion, the main rotating mechanism 1 drives the lower mold mechanism 2 to rotate to directly below the material injection mechanism 3, and the material injection mechanism 3 uniformly injects the compression molding raw material into the lower mold mechanism 2. This is the material injection action. At this time, the second lower mold mechanism 2 is directly opposite to the lifting and spraying mechanism 4, and the lifting and spraying mechanism 4 repeats the mold release agent spraying action on the second lower mold mechanism 2;

[0047] After completion, the main rotation mechanism 1 continues to drive the first lower die mechanism 2 to rotate to directly below the compression molding mechanism 6. The hydraulic jacking mechanism 7 pushes upward to a suitable height. The compression molding mechanism 6 pushes downward so that the compression molding mechanism 6, the first lower die mechanism 2, and the hydraulic jacking mechanism 7 are pressed tightly to form a closed compression molding space until the compression molding raw materials in the lower die mechanism 2 are molded. This is the compression molding action. After completion, the compression molding mechanism 6 resets. Then, the hydraulic jacking mechanism 7 jacks up the household appliance plastic fittings in the lower die mechanism 2 by a certain distance so that the household appliance plastic fittings do not adhere to the lower die mechanism 2. The hydraulic jacking mechanism 7 resets. This is the demolding action;

[0048] At this time, the lifting and spraying mechanism 4 continues to repeat the demolding agent spraying action on the third lower die mechanism 2, and the feeding mechanism 3 continues to repeat the feeding action on the second lower die mechanism 2, and so on;

[0049] After completion, the main rotation mechanism 1 continues to drive the first lower die mechanism 2 to rotate to directly below the flipping and discharging mechanism 5, so that the lower die mechanism 2 is clamped into the flipping and discharging mechanism 5. The flipping and discharging mechanism 5 flips the lower die mechanism 2 by 180°, so that the household appliance plastic fittings in the lower die mechanism 2 fall onto the conveyor belt. The flipping and discharging mechanism 5 flips the lower die mechanism 2 by 180° again to reset the lower die mechanism 2. This is the discharging action;

[0050] After completion, the main rotation mechanism 1 drives the first lower die mechanism 2 to rotate to directly below the lifting and spraying mechanism 4, and the lifting and spraying mechanism 4 repeats the demolding agent spraying action on the lower die mechanism 2, and so on.

[0053] The lower die mechanism 2 includes a lower die plate 202 which is rotatably arranged on the end surface of the corresponding position of the rotating column 106. A detachable lower die body 203 is arranged inside the lower die plate 202. A push plate 204 is slidably arranged at the bottom of the lower die plate 202. A number of push rods are arranged at corresponding positions on the push plate 204. The push rods penetrate through the lower die plate 202 and the lower die body 203, and the front ends of the number of push rods are flush with the inner surface of the lower die body 203 at the initial position. An insertion block 201 is fixed on the outer wall of the lower die plate 202.

[0054] In this embodiment, a suitable lower die body 203 is selected according to the shape production requirements of the household appliance plastic fittings;

[0055] After the compression molding action, the hydraulic jacking mechanism 7 jacks up the push plate 204 upwards, so as to jack up a number of push rods out of the lower die body 203, so that the household appliance plastic fittings formed in the lower die body 203 are not adhered to the inner surface of the lower die body 203;

[0056] After completion, the hydraulic jacking mechanism 7 resets, drives a number of push rods to reset, and enables the flipping block 201 to cooperate with the flipping feeding mechanism 5 to drive the lower die mechanism 2 to rotate 180°, so that the household appliance plastic fittings formed in the lower die body 203 fall off.

An insertion groove block 502 is fixed on the output shaft of the cam rotating member 501, and the thickness of the insertion groove of the insertion groove block 502 is the same as the height of the insertion block 201.

[0063] In this embodiment, the rotating column 106 drives the lower die mechanism 2 to rotate to directly below the flipping and discharging mechanism 5, so that the insertion block 201 is inserted into the insertion groove block 502. The cam rotating member 501 drives the insertion groove block 502 to flip 180°, thereby driving the insertion block 201 to rotate 180°, driving the entire lower die mechanism 2 to rotate 180°, causing the formed household appliance plastic parts in the lower die body 203 to fall off. After completion, the rotating member 501 drives the insertion groove block 502 to flip and reset again, thereby driving the insertion block 201 to rotate 180°, and resetting the entire lower die mechanism 2.

A detachable upper die 602 is provided on the push rod of the second hydraulic component 601. In the initial position, the upper die 602 is located above the second spraying component.

[0065] In this embodiment, a suitable upper die 602 is selected according to the shape production requirements of the household appliance plastic parts;

[0066] During the compression molding action, the second hydraulic component 601 pushes the upper die 602 to tightly abut against the lower die plate 202, forming a closed compression molding space, so that the compression molding raw materials inside the lower die body 203 are molded. After molding, the second hydraulic component 601 drives the upper die 602 to rise and reset, and the second spraying component sprays the release agent on the lower side of the upper die 602.

[0067] The hydraulic jacking mechanism 7 includes a third hydraulic component 703 which is fixed on the bottom plate 101. A force-bearing plate 701 is fixed on the third hydraulic component 703.

A number of vertically upward electric push rods 702 are provided on the force-bearing plate 701, and the electric push rods 702 are directly opposite to the position of the push plate 204.

[0068] In this embodiment, during the compression molding action, the third hydraulic component 703 pushes the force-bearing plate 701 upward until it abuts against the lower die plate 202. The second hydraulic component 601 pushes the upper die 602 to tightly abut against the lower die plate 202 for the compression molding action. After molding, the upper die 602 is separated from the lower die plate 202, and the electric push rods 702 are pushed out to push the push plate 204 upward, thereby driving the push rod to push out the lower die body 203.

[0069] Working principle of the utility model: Select a suitable lower die body 203, a material injection part 303 and an upper die 602 according to the shape production requirements of household appliance plastic fittings;

The first hydraulic component 401 adjusts the vertical distance between the first spray part 402 and the lower die body 203, and the first spray part 402 sprays the release agent onto the inner surface of the lower die body 203. This is the release agent spraying action;

[0071] After completion, the main rotation mechanism 1 drives the lower die mechanism 2 to rotate to directly below the material injection mechanism 3. The transverse movement lead screw part 301 adjusts the front and rear positions of the material injection part 303, and the longitudinal movement lead screw part 304 adjusts the left and right positions of the material injection part 303, so that the material injection part 303 can uniformly inject materials at a suitable position. The material injection part 303 is used to inject compression molding raw materials into the lower die body 203. This is the material injection action. At this time, the second lower die mechanism 2 is directly opposite to the lifting spray mechanism 4, and the lifting spray mechanism 4 repeats the release agent spraying action on the second lower die mechanism 2;

[0072] After completion, the main rotation mechanism 1 continues to drive the first lower die mechanism 2 to rotate to directly below the compression molding mechanism 6. The third hydraulic component 703 pushes the force receiving plate 701 upward until it abuts against the lower die plate 202. The second hydraulic component 601 pushes the upper die 602 to tightly abut against the lower die plate 202 for compression molding. After molding, the second hydraulic component 601 drives the upper die 602 to rise and reset. The electric push rod 702 is pushed out to push the push plate 204 upward, thereby driving the push rod to eject the lower die body 203. This is the compression molding action, so that the household appliance plastic fittings molded in the lower die body 203 do not adhere to the inner surface of the lower die body 203;

[0073] At this time, the lifting spray mechanism 4 continues to repeat the release agent spraying action on the third lower die mechanism 2, and the material injection mechanism 3 continues to repeat the material injection action on the second lower die mechanism 2, and so on;

[0074] After completion, the rotating column 106 drives the lower die mechanism 2 to rotate to directly below the flipping and discharging mechanism 5, causing the insertion block 201 to be inserted into the insertion slot block 502. The cam rotating part 501 drives the insertion slot block 502 to flip 180°, thereby driving the insertion block 201 to rotate 180°, driving the entire lower die mechanism 2 to rotate 180°, causing the formed household appliance plastic fittings in the lower die body 203 to fall off onto the conveyor belt. After completion, the rotating part 501 drives the insertion slot block 502 to flip and reset again, thereby driving the insertion block 201 to rotate 180°, causing the entire lower die mechanism 2 to reset. The flipping and discharging mechanism 5 flips the lower die mechanism 2, causing the household appliance plastic fittings in the lower die mechanism 2 to fall onto the conveyor belt. The flipping and discharging mechanism 5 flips the lower die mechanism 2 again to reset the lower die mechanism 2. This is the discharging action;

[0075] After completion, the main rotating mechanism 1 drives the first lower die mechanism 2 to rotate to directly below the lifting and spraying mechanism 4, and the lifting and spraying mechanism 4 repeats the release agent spraying action on the lower die mechanism 2, and so on.

[0076] In summary, the main rotating mechanism 1 drives the four lower die mechanisms 2 to rotate to the designated positions, realizing continuous operations of spraying release agent, injecting material, compression molding and ejection, and discharging simultaneously, improving production efficiency;

[0077] By adjusting the injection position through the injection mechanism 3, uniform injection into the lower die mechanism 2 is realized, improving production quality;

[0078] During the compression molding action, the compression molding mechanism 6 cooperates with the hydraulic jacking mechanism 7. The compression molding mechanism 6 presses downwards, and the hydraulic jacking mechanism 7 jacks upwards to achieve force balance, making the compression molding effect better and effectively protecting the equipment and extending the service life of the equipment. After the compression molding action is completed, the hydraulic jacking mechanism 7 cooperates with the lower die mechanism 2, and the electric push rod 702 ejects the lower die body 203 through the push rod, so that the formed household appliance plastic fittings in the lower die body 203 do not adhere to the inner surface of the lower die body 203, improving the discharging efficiency;

[0079] Through the cooperation of the flipping and discharging mechanism 5 and the lower die mechanism 2, the lower die mechanism 2 is reciprocally flipped to realize finished product discharging, and at the same time, it is convenient for the lifting and spraying mechanism 4 to spray the release agent on the lower die mechanism 2, improving production efficiency;

[0080] Through the cooperation of the lifting and spraying mechanism 4 and the lower die mechanism 2, the lifting and spraying mechanism 4 sprays the release agent on the lower die mechanism 2, making the release agent better for demolding and improving production efficiency.
