Description

Technical Field

[0001] This utility model relates to the field of injection molding equipment technology, and in particular to an injection molding machine for integral molding of washing machine control panels. Background Technology

[0002] A washing machine is a cleaning appliance that uses electrical energy to generate mechanical action to wash clothes. Based on its rated washing capacity, it is divided into two categories: household and commercial. Household washing machines mainly consist of an outer casing, control panel, washing and spin-drying tub, transmission and control system, and some also have a heating element. The washing machine control panel is usually injection molded and integrates elements such as a display screen, buttons, and knobs. It is the operation center of the washing machine, controlling all its functions. High-end washing machine control panels may also have intelligent features and touchscreen functionality.

[0003] Injection molding machines are the main molding equipment used to make various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. Injection molding machines can heat plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity.

[0004] During injection molding, the material is first fed into the melting component of the injection molding machine for melting. When injection molding a product, different types of raw materials may be used. Simply stirring during melting may not be enough to ensure uniformity. The entry of different materials may result in local accumulation, which will affect the quality of the product. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose an injection molding machine for the integrated molding of a washing machine control panel, so as to solve the problem that different types of raw materials, which are not uniformly mixed by stirring during melting, may cause local accumulation when different materials enter.

[0006] To achieve the above objectives, this utility model provides an injection molding machine for integral molding of a washing machine control panel, including a housing, an injection molding device fixedly connected to the upper end of the housing, a mold fixedly connected to the left side of the injection molding device, and a feeding mechanism provided at the upper end of the injection molding device.

[0007] The feeding mechanism includes a feeding shell fixedly connected to the upper end of the injection molding device. A shelf is fixedly connected inside the feeding shell, and a support plate is fixedly connected to the outer side of the feeding shell. A motor is fixedly connected to the upper end of the support plate, and a reciprocating lead screw is fixedly connected to the output end of the motor. A lead screw nut is engaged with the outer side of the reciprocating lead screw. Limit rods are slidably connected to both sides of the lead screw nut. The upper end of the limit rod is fixedly connected to the inner wall of the support plate. A moving rod is fixedly connected to the lower end of the lead screw nut. A cylinder is rotatably connected to the lower end of the moving rod. Feed ports are opened on both sides of the upper end of the cylinder. A rectangular rod is slidably connected inside the reciprocating lead screw, and the lower end of the rectangular rod is fixedly connected to the upper end of the cylinder.

[0008] Preferably, a horizontal block is fixedly connected to both sides of the cylinder, and a stirring rod is slidably connected inside the horizontal block.

[0009] Preferably, the lower ends of the two stirring rods are fixedly connected to a ring, and the ring is rotatably connected to the shelf.

[0010] Preferably, the shelf is tapered.

[0011] Preferably, the length of the cylinder is the same as the length of the reciprocating lead screw.

[0012] The beneficial effects of this utility model are:

[0013] The reciprocating screw and rectangular rod cause the cylinder to rotate while moving up and down, which in turn causes the position of the feed inlet to change continuously. This allows the material located at the top of the shelf to enter the injection molding unit irregularly, resulting in better mixing between different materials and improving product quality.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0022] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0023] like Figure 1-4 As shown, this utility model provides an injection molding machine for integral molding of a washing machine control panel, including a housing 1, an injection molding device 2 fixedly connected to the upper end of the housing 1, a mold 4 fixedly connected to the left side of the injection molding device 2, and a feeding mechanism provided at the upper end of the injection molding device 2.

[0024] The feeding mechanism includes a feeding shell 3 fixedly connected to the upper end of the injection molding device 2. A shelf 9 is fixedly connected inside the feeding shell 3, used for temporary material storage. The shelf 9 is tapered, providing some guidance for the material. A support plate 5 is fixedly connected to the outer side of the feeding shell 3. A motor 6 is fixedly connected to the upper end of the support plate 5. The motor 6 is a drive device. In the prior art, a reciprocating screw 8 is fixedly connected to the output end of the motor 6, driving the reciprocating screw 8 to rotate. A screw nut 16 is engaged with the outer side of the reciprocating screw 8. When the reciprocating screw 8 rotates, it drives the screw nut 16 to move up and down continuously. Limiting rods 15 are slidably connected to both sides of the screw nut 16. The upper end of the limiting rod 15 is fixedly connected to the inner wall of the support plate 5, limiting the rotation of the screw nut 16. This allows the lead screw nut 16 to move stably up and down. The lower end of the lead screw nut 16 is fixedly connected to a moving rod 7. The movement of the lead screw nut 16 drives the moving rod 7 to move. The lower end of the moving rod 7 is rotatably connected to a cylinder 13. The up and down movement of the moving rod 7 drives the cylinder 13 to move up and down. Both sides of the upper end of the cylinder 13 are provided with feed ports 14. The material enters the interior of the cylinder 13 through the feed ports 14 and then falls into the interior of the injection molding device 2. The reciprocating lead screw 8 is slidably connected to a rectangular rod 17. The rectangular rod 17 can move up and down relative to the reciprocating lead screw 8. At the same time, when the reciprocating lead screw 8 rotates, it drives the rectangular rod 17 to rotate. The lower end of the rectangular rod 17 is fixedly connected to the upper end of the cylinder 13. When the rectangular rod 17 rotates, it drives the cylinder 13 to rotate. The length of the cylinder 13 is the same as the length of the reciprocating lead screw 8.

[0025] During operation, the required materials are poured into the feed housing 3. The shelf 9 prevents the materials from moving downwards, temporarily storing them at the upper end of the feed housing 3. At this time, the motor 6 operates, driving the reciprocating screw 8 to rotate. The rotation of the reciprocating screw 8 causes the screw nut 16 to move up and down continuously under the constraint of the limit rod 15. As the screw nut 16 moves, it drives the moving rod 7 to move up and down continuously. The moving rod 7 then drives the cylinder 13 to move up and down continuously. Simultaneously, the rotation of the reciprocating screw 8 drives the rectangular rod 17 to rotate, causing the fixedly connected cylinder 13 to rotate. When the material enters the cylinder 13 through the feed port 14, it then enters the injection molding device 2. The heating device inside the injection molding device 2 melts the material, and the molten material is pushed by the spiral feed rod to be injected into the mold 4 to complete the injection molding process. The reciprocating screw 8 and the rectangular rod 17 cause the cylinder 13 to rotate while moving up and down, which makes the position of the feed port 14 constantly change. This allows the material located at the top of the shelf 9 to enter the injection molding device 2 irregularly, resulting in better mixing between different materials and improving product quality.

[0026] like Figure 3As shown, horizontal blocks 12 are fixedly connected to both sides of the cylinder 13. A stirring rod 11 is slidably connected inside the horizontal block 12. A ring 10 is fixedly connected to the lower end of the two stirring rods 11. The ring 10 is rotatably connected to the shelf 9. When the cylinder 13 rotates, it drives the horizontal blocks 12 to rotate. The rotation of the horizontal blocks 12 causes the stirring rods 11 to move. Since the stirring rods 11 and the horizontal blocks 12 are slidably connected, there is no interference. This further improves the mixing of the material inside the feed shell 3.

[0027] Working principle: During operation, the required material is poured into the feed housing 3. The shelf 9 prevents the material from moving downwards, temporarily storing it at the upper end of the feed housing 3. At this time, the motor 6 operates, driving the reciprocating screw 8 to rotate. The rotation of the reciprocating screw 8 causes the screw nut 16 to move up and down continuously under the constraint of the limit rod 15. As the screw nut 16 moves, it drives the moving rod 7 to move up and down continuously. The moving rod 7 then drives the cylinder 13 to move up and down continuously. Simultaneously, the rotation of the reciprocating screw 8 drives the rectangular rod 17 to rotate, causing the fixedly connected cylinder 13 to rotate. During the movement, the material enters the cylinder 13 through the feed port 14 and then enters the injection molding device 2. The raw material is melted by the heating device inside the injection molding device 2. The melted material is then pushed by the spiral feed rod and injected into the mold 4 to complete the injection molding process. The reciprocating screw 8 and the rectangular rod 17 cause the cylinder 13 to rotate while moving up and down. This causes the position of the feed port 14 to change continuously, so that the material located at the top of the shelf 9 can enter the injection molding device 2 irregularly, resulting in better mixing between different materials and improving product quality.
