Technical Field
[0001] This utility model relates to the field of injection molding machine technology, specifically to a moving template for a two-color injection molding machine. Background Technology
[0002] Injection molding machines, also known as injection molding machines or injection machines, are mechanical devices that melt thermoplastic or thermosetting plastics by heating, inject them into a mold cavity under high pressure, and then cool and solidify them to obtain products of the desired shape. They are one of the most commonly used pieces of equipment in the plastics processing industry and are widely used in the automotive, home appliance, packaging, medical, and electronics industries. In the field of injection molding, two-color injection molding technology is particularly popular because it enables the creation of diverse designs for product appearance and function.
[0003] With the widespread application of plastic products in automobiles, home appliances, electronics, and packaging, the market has placed higher demands on the appearance, performance, and function of plastic products. Two-color injection molding technology, as an efficient process that can achieve one-piece molding of multiple colors and materials, has gradually become one of the key technologies for industry development. However, existing moving templates are usually driven by hydraulic cylinders or gear racks, which are complex in structure, have many parts, are prone to wear and failure, and have high maintenance costs. At the same time, due to mechanical transmission errors and the lag of the hydraulic system, the positioning accuracy of existing moving templates is difficult to meet the requirements of high-precision injection molding, affecting product quality. Furthermore, since existing moving templates are driven by hydraulic cylinders or gear racks, lubricating oil needs to be added to the transmission structure. However, during the use of the injection molding machine, the overflowing lubricating oil will drip down along the moving template, causing the lubricating oil to adhere to the surface of the moving template, thus affecting the aesthetics of the device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 As shown, a movable template for a two-color injection molding machine includes a base plate 1 and a back plate 2. The back plate 2 is fixed to the top of the base plate 1. A template body 3 is provided on one side of the back plate 2. The back plate 2 and the base plate 1 form an L-shape. The template body 3 is installed on the inner wall of the base plate 1 and the back plate 2, and is supported by the back plate 2 and the base plate 1, thereby improving the stability of the device. Two sets of tie rod brackets 4 are respectively provided on the outer side of the back plate 2 and the template body 3. Tie rod holes 5 are opened on the inner wall of both sets of tie rod brackets 4. Guide sleeves 6 are provided on the inner wall of the tie rod holes 5. Pressure caps 7 for limiting the guide sleeves 6 are provided on the inner wall of the tie rod holes 5. By opening tie rod holes 5 on their inner walls, the two sets of tie rod brackets 4 can be used to guide the tie rods. The guide sleeve 6 is provided on the inner wall of the pull rod hole 5 to limit the movement of the pull rod sliding on the inner wall of the pull rod hole 5. The pressure cap 7 is provided on the inner wall of the pull rod hole 5 to fix the guide sleeve 6 to the inner wall of the pull rod hole 5. It should be noted that the through groove 8 is opened on the inner wall of the template body 3, and there are three sets of through grooves 8. The inner wall of the template body 3 is provided with a horizontally arranged central deep cavity hole 9. Since the inner wall of the template body 3 is provided with through grooves 8 and central deep cavity holes 9 respectively, the template body 3 can achieve lightweight. At the same time, the central deep cavity hole 9 is provided in the center of the template body 3, so that the template body 3 can be equipped with an extended turntable shaft, making the turntable rotation accuracy higher.
[0024] Two sets of turntable roller brackets 10 are fixed to the bottom of the base plate 1. The inner walls of both sets of turntable roller brackets 10 are provided with positioning holes 11. The turntable roller brackets 10 can install the main body and the turntable rollers. At the same time, the positioning holes 11 on the inner walls of the turntable roller brackets 10 prevent the main body from shifting during installation, thus avoiding affecting the installation efficiency of the template body 3 and the turntable rollers. Four sets of locking shaft brackets 12 are installed on one side of the template body 3. The inner walls of the four sets of locking shaft brackets 12 are provided with limiting holes 13. The inner walls of the template body 3 are provided with reinforcing ribs 14, and there are two sets of reinforcing ribs 14. The multiple sets of locking shaft brackets 12 can install the template body 3 and the locking shaft. At the same time, the limiting holes 13 can connect the template body 3 and the locking shaft, thereby limiting the template body 3. Since there are corresponding reinforcing ribs 14 between the locking shaft brackets 12, the compressive strength of the template body 3 can be guaranteed.
[0025] The top of the back plate 2 is fixed with a motor bracket 15 and a positioning cylinder bracket 16, and two sets of motor brackets 15 are provided. The arrangement of the motor brackets 15 and the positioning cylinder brackets 16 allows the motor and positioning cylinder to be installed on the top of the back plate 2 respectively. A mounting plate 17 is provided on one side of the locking shaft bracket 12. The inner wall of the mounting plate 17 is provided with mounting holes 18 and through holes 19. Since the dimensions of the mounting holes 18 and through holes 19 are the same as the dimensions of the hydraulic cylinder or lead screw, it is convenient to install the hydraulic cylinder or lead screw on the outside of the template body 3. On the side, a guide platform 20 is fixed on the outer side of the template body 3, and a vertically installed oil filling hole 21 is opened on the inner wall of the tie rod bracket 4. The guide platform 20 can guide the lubricating oil, and the oil filling hole 21 can add the lubricating oil to the guide sleeve 6, thereby reducing the wear between the tie rod and the guide sleeve 6. It should be noted that a guide platform 20 for guiding the lubricating oil is added to the upper end of the template body 3, and the guide platform 20 is arc-shaped so that the overflowing lubricating oil drips down, which can effectively improve the phenomenon of lubricating oil flowing down the surface of the template body 3 from the overflow point, resulting in an unsightly machine.
[0026] When the injection molding machine is working, the template body 3 is first installed on the turntable support roller through the turntable support roller bracket 10. Then, the motor and positioning cylinder are installed on the motor bracket 15 and positioning cylinder bracket 16 in sequence. After that, the pull rod is inserted into the pull rod hole 5 opened in the inner wall of the pull rod bracket 4. Since the pull rod hole 5 is provided with a guide sleeve 6, lubricating oil can be added to the gap between the guide sleeve 6 and the pull rod hole 5 through the oiling hole 21. When the template body 3 moves and drives the pull rod bracket 4 to slide along the pull rod, the guide sleeve 6 and the lubricating oil can reduce the wear between the pull rod and the guide sleeve 6. Then, the template body 3 is connected to the locking shaft through the limiting hole 13 opened in the inner wall of the locking shaft bracket 12. At the same time, since the locking shaft bracket 12 is provided with corresponding reinforcing ribs 14, the compressive strength of the template body 3 can be guaranteed. At the same time, since the through groove 8 and the central deep cavity hole 9 are opened in the inner wall of the template body 3, the template body 3 can be lightweight and can be equipped with an extended turntable shaft, so that the turntable rotation accuracy is higher.
