Description

Technical Field

[0001] The invention relates to the technical field of washing machine control panel production, and in particular to an injection molding machine used for integrally molding a washing machine control panel. Background Art

[0002] Washing machines are cleaning appliances that use electrical energy to generate mechanical action to wash clothes. They are divided into two categories according to their rated washing capacity: household and collective. Household washing machines are mainly composed of an outer shell, a control panel, a washing and dehydrating barrel, a transmission and control system, and some are also equipped with a heating device. The control panel of a washing machine is usually injection molded by an injection molding machine, integrating elements such as a display, buttons, and knobs. It is the operating center of the washing machine and controls all functions of the washing machine. High-end washing machine control panels will also have functions such as intelligence and touch screens.

[0003] Injection molding machine is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it eject and fill the mold cavity.

[0004] Before using the injection molding machine, it is usually necessary to use drying equipment to dry the raw materials, so as to reduce the excess moisture in the raw materials and improve the injection molding quality. Although the raw materials have been dried before the injection molding machine works, the dried raw materials are stored in a relatively humid environment, resulting in moisture inside the raw materials. If the raw materials containing moisture are directly put into the injection molding machine for heating and melting, it will affect the injection molding quality of the entire washing machine control panel; if the raw materials are repeatedly dried with the help of drying equipment, the injection molding time of the washing machine control panel will be extended, thereby affecting the injection molding efficiency of the entire washing machine control panel.

[0011] Optionally, two arc plates are symmetrically arranged on the top of the filter plate, and two rotating blocks are installed on the top of the two arc plates. The two rotating blocks are rotatably connected to the first sliding block close to them, and multiple fixing rods are installed on the outer walls of both sides of the vertical plate close to the stirring blades, and the outer walls on the side where the two arc plates are close to each other are abutted against the multiple fixing rods.

[0012] Optionally, the anti-clogging mechanism includes a round block arranged below the filter plate, a second electric telescopic rod is installed at the bottom end of the rotating shaft, the telescopic end of the second electric telescopic rod passes through the filter plate and is connected to the round block, and an elastic sealing ring is installed inside the hopper, and the diameter of the elastic sealing ring is adapted to the diameter of the round block.

[0013] Optionally, two mounting seats are installed on the outer wall of the round block, and a rotating rod is rotatably installed inside the two mounting seats.

[0014] Optionally, a receiving groove is provided inside the two rotating rods, a second sliding groove is provided on one side inner wall of the two receiving grooves, and a second sliding block is installed inside the two second sliding grooves.

[0015] Optionally, a rectangular plate is installed at one end of the two second sliding blocks away from the second slide groove, and a plurality of arc blocks adapted to the filter grooves opened inside the filter plates are installed on the top of the two rectangular plates, and the two rectangular plates and the plurality of arc blocks can be stored in the corresponding storage grooves.

[0016] Optionally, a discharge pipe is installed at one end of the hopper close to the barrel, a circular shell is installed on the outer wall of the temporary storage box, the inner bottom surface of the circular shell is inclined, and a discharge channel is provided at the end of the circular shell close to the lower inner bottom surface.

[0017] The beneficial effects of the present invention are:

[0018] 1. In the present invention, a temporary storage box is arranged above the hopper, and a drying mechanism is arranged inside the temporary storage box. After the injection molding raw materials are put into the temporary storage box, the raw materials can be fully dried with the help of the drying mechanism to avoid the injection molding raw materials containing moisture, which affects the injection molding quality of the washing machine control panel. In addition, the injection molding raw materials can also be preheated at the same time, so that the injection molding raw materials can be heated more evenly when entering the barrel, thereby shortening the melting time and improving production efficiency.

[0019] 2. In the present invention, during the process of drying the injection molding raw materials, the weighed masterbatch can be simultaneously put into the temporary storage box and mixed and stirred with the aid of a plurality of rotating stirring blades, so as to facilitate sufficient mixing between the masterbatch and the injection molding raw materials, thereby ensuring good color stability after the subsequent barrel melts them, thereby improving the appearance quality of the washing machine control panel, improving the processing performance of the injection molding raw materials, and improving production efficiency.

[0020] 3. In the present invention, when the injection molding raw material passes through the bottom of the hopper downward into the interior of the barrel, the injection molding raw material is prone to blockage when passing through the discharge port. If the injection molding raw material is blocked when passing through the discharge port at the bottom of the hopper, the two rotating rods can be controlled to rotate downward to a vertical state, and the downward extension of the telescopic end of the second electric telescopic rod can be used to drive the round block and the two rotating rods to move downward together, so that the two rotating rods in a vertical state can clear the blocked part at the bottom of the hopper to avoid blockage of the injection molding raw material at the bottom of the hopper, which will slow down the speed of the injection molding raw material entering the barrel, prolong the time for the barrel to heat and melt the injection molding raw material, and thus reduce the injection molding efficiency of the washing machine control panel.

[0021] 4. In the present invention, when the filter plate is filtering the injection molding raw materials, a small amount of injection molding raw materials may be stuck inside the filter groove. The second sliders inside the two second slide grooves are controlled to drive the corresponding rectangular plates and multiple arc blocks to extend upward from the inside of the storage groove, so that the multiple arc blocks can be inserted into the corresponding filter grooves. The circular blocks and the multiple arc blocks are driven to rotate together by the rotating shaft. The multiple arc blocks can be rotated at a certain angle inside the corresponding filter grooves, so that the injection molding raw materials stuck inside the filter grooves can be removed, which is convenient for the subsequent use of the filter plate.

[0040] As a technical optimization solution of the present invention, a driving motor 9 is installed on the top of the mounting plate 8, and the output end of the driving motor 9 is connected to the rotating shaft 19 through the mounting plate 8, and the outer wall of the rotating shaft 19 is installed with a vertical plate 15, and the outer walls of both sides of the vertical plate 15 are installed with stirring blades 12. When the driving motor 9 drives the rotating shaft 19 to rotate, it can simultaneously drive the vertical plate 15 and the stirring blades 12 installed on the outer wall thereof to rotate together inside the temporary storage box 4, and stir the injection molding raw materials inside the temporary storage box 4 to make them dry evenly and fully.

[0041] As a technical optimization solution of the present invention, two first chutes 23 are provided on the other two outer walls of the vertical plate 15, and first sliders 25 are installed inside the two first chutes 23. Elastic and retractable protective cloths 24 are installed between the upper and lower outer walls of the two first sliders 25 and the inner walls of the two sides of the first chutes 23. First linear motors are preset inside the two first chutes 23, and the first linear motors can drive the first sliders 25 to move up and down inside the first chutes 23; because protective cloths 24 are provided between the upper and lower sides of the first sliders 25 and the two ends of the first chutes 23, the injection molding materials can be prevented from entering the first chutes 23 during use inside the temporary storage box 4.

[0042] As a technical optimization scheme of the present invention, two arc plates 17 are symmetrically arranged on the top of the filter plate 14, and two rotating blocks 26 are installed on the top of the two arc plates 17. The two rotating blocks 26 are rotatably connected with the first slider 25 close to them. The outer walls of the two sides of the vertical plate 15 close to the stirring blade 12 are installed with multiple fixed rods 16, and the outer walls of the two arc plates 17 close to each other are in contact with multiple fixed rods 16. A second driving device is preset on the outer wall of one side of the first slider 25, and the output end of the second driving device is connected to the rotating part of the rotating block 26, so that the arc plate 17 can be driven to rotate and adjust inside the temporary storage box 4; because the outer walls of the two sides of the vertical plate 15 are provided with three fixed rods 16, the first slider 25 moves upward, driving the arc plate 17 to move upward to a position flush with each fixed rod 16, ensuring that the two arc plates 17 cooperate with the fixed rod 16, and the interior of the temporary storage box 4 can be separated.

[0043] As a technical optimization solution of the present invention, the anti-blocking mechanism includes a round block 20 arranged below the filter plate 14, a second electric telescopic rod 27 is installed at the bottom end of the rotating shaft 19, the telescopic end of the second electric telescopic rod 27 passes through the filter plate 14 and is connected to the round block 20, and an elastic sealing ring 13 is installed inside the hopper 3, and the diameter of the elastic sealing ring 13 is adapted to the diameter of the round block 20. The telescopic end of the second electric telescopic rod 27 is extended and retracted, which can drive the position of the round block 20 below the filter plate 14 to be adjusted; after the round block 20 moves to the inside of the elastic sealing ring 13, it can cooperate with the elastic sealing ring 13 to block the bottom outlet position of the hopper 3 to prevent the injection molding raw materials from continuing to be discharged downward.

[0044] As a technical optimization solution of the present invention, two mounting seats are installed on the outer wall of the round block 20, and the interior of the two mounting seats is rotatably mounted with a rotating rod 21. A third driving device is preset on the outer wall of one side of the two mounting seats, and the output ends of the two third driving devices are respectively connected to the rotating parts of the two rotating rods 21, so as to drive the two rotating rods 21 to rotate and adjust.

[0045] As a technical optimization solution of the present invention, the two rotating rods 21 are provided with a receiving groove 35, and the inner wall of one side of the two receiving grooves 35 is provided with a second slide groove 34, and the second slider 33 is installed inside the two second slide grooves 34. The second linear motors are preset inside the two second slide grooves 34, and the two second linear motors can respectively drive the two second sliders 33 to move up and down inside the corresponding second slide grooves 34.

[0046] As a technical optimization solution of the present invention, a rectangular plate is installed at one end of the two second sliders 33 away from the second slide groove 34, and a plurality of arc blocks 32 adapted to the filter grooves opened inside the filter plate 14 are installed on the top of the two rectangular plates. The two rectangular plates and the plurality of arc blocks 32 can be stored in the corresponding storage grooves 35. In the process of the two second sliders 33 moving up and down, the two rectangular plates and the plurality of arc blocks 32 arranged on the top can be driven to move up and down inside the storage groove 35.

[0047] As a technical optimization scheme of the present invention, a discharge pipe 5 is installed at one end of the hopper 3 close to the barrel 2, and a circular shell 6 is installed on the outer wall of the temporary storage box 4. The inner bottom surface of the circular shell 6 is inclined, and a discharge channel 10 is provided at the lower end of the circular shell 6 close to the inner bottom surface. If the injection molding material inside the hopper 3 needs to be discharged, the preset valve between the hopper 3 and the barrel 2 can be controlled to be closed, and the preset valve inside the discharge pipe 5 can be controlled to be opened, so that the injection molding material inside the hopper 3 can be discharged to the outside of the machine body 1 through the discharge pipe 5; the injection molding material inside the temporary storage box 4 can be controlled by controlling the telescopic ends of the two first electric telescopic rods 7 to extend upward, pushing the mounting plate 8 and the filter plate 14 and other components to move upward from the interior of the temporary storage box 4, and pushing the injection molding material on the top of the filter plate 14 to the inside of the circular shell 6 for collection. After the injection molding material enters the interior of the circular shell 6, it will be discharged outwardly toward the discharge channel 10 at the lower end, so as to achieve the effect of automatically taking out the remaining injection molding material inside the temporary storage box 4.

[0048] In the present invention, when the user uses the device, the injection molding material is put into the temporary storage box 4 from the opening at the top of the temporary storage box 4 for temporary storage. At this time, the external preset hot air blower can be controlled to start, so that the multiple air outlets 22 at the bottom of the mounting plate 8 can discharge hot air toward the interior of the temporary storage box 4 to dry the injection molding material. While the multiple air outlets 22 discharge the hot air into the interior of the temporary storage box 4, the drive motor 9 is controlled to start, driving the multiple stirring blades 12 to stir the injection molding material, so that the hot air entering the temporary storage box 4 contacts the injection molding material more evenly and fully, thereby improving the drying effect of the injection molding material.

[0049] After the injection molding raw material is dried, the two arc plates 17 can be controlled to rotate upward to a vertical state, and the two sealing plates 28 can be controlled to rotate downward to open, so that the dried injection molding raw material can be discharged downward through the hopper 3 to the inside of the barrel 2, and the injection molding raw material is heated and melted with the help of the barrel 2, and then the melted injection molding raw material is extruded into the injection mold through the nozzle 11 through the extrusion screw arranged inside the barrel 2. After the injection mold cools it, the molded washing machine control panel is discharged downward by opening the two injection molds, and the injection molding of the washing machine control panel can be completed.

[0050] When the injection molding raw materials are put into the temporary storage box 4 as mentioned above, if half of the injection molding raw materials need to be put into the temporary storage box 4, the two groups of corresponding first sliders 25 can be controlled to move upward together inside the first slide groove 23, driving the two arc plates 17 to move upward together to a position flush with the two fixed rods 16 in the middle position. At this time, the injection molding raw materials put into the temporary storage box 4 can be automatically determined as half of the capacity, and there is no need for manual real-time monitoring of the capacity of the injection molding raw materials put.

[0051] In the above-mentioned process of drying the injection molding raw material, the injection molding raw material can also be preheated at the same time, so that the injection molding raw material can be heated more evenly when entering the barrel 2, thereby shortening the melting time and improving production efficiency. In addition, since the initial temperature of the injection molding raw material after preheating has been increased, the barrel 2 only needs to be heated a small amount to reach the required melting temperature, reducing the required heating power of the barrel 2, thereby saving energy and cost, and making the initial temperature of the injection molding raw material more stable, so as to form a more uniform melt after melting, which is conducive to maintaining the stability of the production process, and can also improve the quality of the injection molding of the washing machine control panel.

[0052] Moreover, in the above-mentioned process of drying the injection molding raw materials, the weighed masterbatch can be simultaneously put into the interior of the temporary storage box 4, and mixed and stirred with the help of multiple rotating stirring blades 12, so that the masterbatch and the injection molding raw materials are fully mixed, so that the color stability of the subsequent barrel 2 after melting is good, the appearance quality of the washing machine control panel is improved, the processing performance of the injection molding raw materials is improved, and the production efficiency is improved; and while the masterbatch and the injection molding raw materials are mixed, the two arc plates 17 are controlled to move upward inside the temporary storage box 4, so that the multiple filter grooves inside the filter plate 14 are exposed, and the injection molding raw materials at the bottom layer can be turned upward, as the multiple stirring blades 12 continue to rotate, the smaller particles in the injection molding raw materials can preferentially fall downward and enter the interior of the barrel 2 for heating and melting treatment, and then the two blocking plates 28 are controlled to rotate downward and open, and the remaining larger particles are discharged downward and sent to the interior of the barrel 2, avoiding the injection molding raw materials of different volumes being sent into the interior of the barrel 2 together, resulting in uneven heating and melting of the injection molding raw materials by the barrel 2, which affects the subsequent injection molding of the washing machine control panel.

[0053] After the two blocking plates 28 rotate downward, a large amount of injection molding material located above the filter plate 14 can be quickly discharged through the two discharge ports 29. In order to avoid the injection molding material being blocked at the discharge port 29, the two rotating rods 21 can be controlled to rotate downward together to be in a vertical state. As the rotating shaft 19 drives the round block 20 to rotate, the two rotating rods 21 can be driven to rotate together. After the two rotating rods 21 rotate to a position close to the two blocking plates 28, the two rotating rods 21 are controlled to rotate upward together, so that the two blocking plates 28 can be pushed upward to facilitate the pushing of the injection molding material passing through the discharge port 29, thereby avoiding the injection molding material being blocked inside the discharge port 29, which affects the injection molding material discharge efficiency.

[0054] Moreover, when the injection molding raw material passes through the bottom of the hopper 3 downward into the interior of the barrel 2, due to the narrow bottom discharge port of the hopper 3, the injection molding raw material is more likely to be blocked when passing through the discharge port. For example, if the injection molding raw material is blocked when passing through the discharge port at the bottom of the hopper 3, the two rotating rods 21 can be controlled to rotate downward to a vertical state, and the downward extension of the telescopic end of the second electric telescopic rod 27 can be used to drive the round block 20 and the two rotating rods 21 to move downward together, so that the two vertical rotating rods 21 can clear the blocked part at the bottom of the hopper 3 to avoid blockage of the injection molding raw material at the bottom of the hopper 3, which will slow down the speed at which the injection molding raw material enters the barrel 2, prolong the time for the barrel 2 to heat and melt the injection molding raw material, and thus reduce the injection molding efficiency of the washing machine control panel.

[0055] When the filter plate 14 is filtering the injection molding raw materials, a small amount of injection molding raw materials may be stuck inside the filter groove. At this time, the second sliders 33 inside the two second slide grooves 34 can be controlled to drive the corresponding rectangular plates and multiple arc blocks 32 to extend upward from the inside of the storage groove 35, so that the multiple arc blocks 32 can be inserted into the corresponding filter groove. With the help of the rotating shaft 19, the round block 20 and the multiple arc blocks 32 are driven to rotate together. The multiple arc blocks 32 can be rotated at a certain angle inside the corresponding filter groove, so that the injection molding raw materials stuck inside the filter groove can be removed, which is convenient for the subsequent use of the filter plate 14.

[0056] After the injection molding of the washing machine control panel is completed, there are some injection molding materials remaining inside the temporary storage box 4 and the hopper 3. If these injection molding materials are still needed next time, the valve set between the hopper 3 and the barrel 2 can be directly controlled to be closed, and the valve inside the discharge pipe 5 can be controlled to be closed together, and then the two arc plates 17 are controlled to rotate upward together to a vertical state, and then the two sets of first sliding blocks 25 are used to move upward inside the first slide groove 23, driving the two arc plates 17 to move together to a position flush with the two top fixed rods 16, and then the two arc plates 17 are controlled to rotate downward together to a horizontal state, so that the two arc plates 17 at this time cooperate with the two top fixed rods 16 to block the top opening of the temporary storage box 4, so that the remaining injection molding materials can be temporarily stored inside the temporary storage box 4 and the hopper 3.

[0057] When other injection molding materials need to be replaced next time, the valve inside the discharge pipe 5 can be controlled to open first, so that the injection molding materials inside the hopper 3 can be discharged outward through the discharge pipe 5, and after controlling the two rotating rods 21 to rotate downward to an inclined state, the rotating shaft 19 drives the round block 20 and the two rotating rods 21 to rotate together, so that the injection molding materials inside the hopper 3 can be discharged outward more quickly.

[0058] The injection molding raw material above the filter plate 14 that has not yet fallen downward into the hopper 3 can be extended upward with the help of the telescopic ends of the two first electric telescopic rods 7, pushing the mounting plate 8, the filter plate 14 and other components to move upward from the interior of the temporary storage box 4, and the injection molding raw material on the top of the filter plate 14 is pushed out to the interior of the circular shell 6 for collection. After the injection molding raw material enters the interior of the circular shell 6, it will be discharged outwardly toward the discharge channel 10 at the lower end, thereby achieving the effect of automatically taking out the remaining injection molding raw material in the temporary storage box 4, without the need for manual removal of the remaining injection molding raw material, which is convenient for the subsequent use of the machine body 1 and improves the applicability of the machine body 1.
