In the actual production process, with the increase in labor costs, the molding cycle of plastic parts has increasingly become a hot topic of concern for enterprises. How to effectively optimize and improve the injection molding cycle has begun to become the key research object of various technical personnel; When processing automobile decorative strips, first, the raw materials need to be processed to make them melt, and then put into the corresponding mold or forming groove so that the decorative strips can be injection molded. However, in the existing injection molding equipment, after injection molding, there will be certain particles or burrs on the surface. If there are burrs on the surface of the decorative strip, it will cause the surface display effect of the decorative strip to be relatively poor after painting, which will further affect the finished product of the decorative strip.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1.

When the cooling component is in use, through an external water pump, the liquid can continuously circulate in the circulation pipeline to accelerate the molding of the decorative strips. At the same time, the heat absorption plate of the device will absorb the heat at the material inlet. Because the heat absorption plate is connected to the cooling plate, the carrier electrons in the heat absorption plate will move into the cooling plate, resulting in a temperature difference between the heat absorption plate and the cooling plate. Combined with the circulation pipeline, the molding of the decorative strips can be assisted more quickly.

[0016] 4. When the grinding component of the device is in use, it can grind the display surface and corners of the decorative strips to reduce the particles and burrs on the display surface.

At the same time, because there is a belt installed between the pulleys, it can drive the grinding wheel to rotate together. When the grinding wheel grinds the decorative strips, the clamping component can adjust the tightness of the decorative strips, and then cooperate with the grinding wheel to more effectively polish and grind the decorative strips, so that when the decorative strips are painted later, the painting effect will not be affected by the uneven surface.

Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment: As Figures 1-8 shown, the present invention provides a technical solution for an injection molding equipment for vehicle decorative strips with a burr grinding function, including an injection molding equipment main body 1 and a controller 11. It is characterized in that: the injection molding equipment main body 1 includes a pretreatment tank 2 and a forming block 3. A support frame 41 is installed outside the pretreatment tank 2, and the forming block 3 is installed at the bottom of the pretreatment tank 2. A grinding assembly 4 is installed at the output end of the injection molding equipment main body 1, a cooling assembly 8 is installed inside the forming block 3, and a stirring assembly 5 is installed inside the pretreatment tank 2. The pretreatment tank 2 can pre-treat the raw materials, the forming block 3 can cooperate with the pretreatment tank 2 to process and form the decorative strip, and the grinding assembly 4 can grind and polish the decorative strip; When in use, the device can injection-mold the decorative strips for vehicles through the main body 1 of the injection molding equipment. Specifically, when in use, the pretreatment box 2 can process the raw materials. During the processing, the pretreatment box 2 can continuously heat the raw materials inside it so that the raw materials can melt. After the raw materials enter the forming block 3, they can be formed through the forming groove 31 of the forming block 3. During the process of forming the decorative strip by the forming block 3, the cooling component 8 can also accelerate the forming of the decorative strip. After the formed decorative strip is discharged, the grinding component 4 can grind the outer surface and side surface of the decorative strip to remove the burrs on the decorative strip, so that when the decorative strip is painted later, color difference of the decorative strip will not occur. At the same time, during the grinding process of the decorative strip, the clamping component 9 can tighten or loosen the decorative strip by itself, so that when the decorative strip is being ground, the decorative strip can be prevented from breaking due to excessive force.

[0020] As Figure 2 and Figure 7 shown, in this embodiment, specifically, a stirring motor 21 is installed above the pretreatment box 2. A chute 22 is formed on the inner wall of the pretreatment box 2. The output end of the stirring motor 21 is provided with the stirring component 5. The stirring component 5 is matched with the chute 22. The stirring component 5 includes a transmission rod 51. The transmission rod 51 is connected to the stirring motor 21. A plurality of stirring rods 52 are installed on the transmission rod 51. The other ends of the plurality of stirring rods 52 are respectively installed inside the chute 22. A scraper 53 is installed between two adjacent stirring rods 52. The scraper 53 is in contact with the inner wall of the pretreatment box 2. When the pretreatment box 2 of the device is in use, it can melt the raw materials and stir the raw materials. Specifically, when in use, the stirring motor 21 can drive the stirring component 5 in the pretreatment box 2. When the stirring motor 21 drives the transmission rod 51 to rotate, the transmission rod 51 will drive the stirring rods 52 to rotate together. Since the other end of the stirring rod 52 is connected to the chute 22 of the pretreatment box 2, the stirring rod 52 can be prevented from tilting due to excessive force during the stirring process. At the same time, a scraper 53 is installed between two adjacent stirring rods 52. Therefore, when the transmission rod 51 drives the stirring rods 52 to rotate, the scraper 53 will be driven to rotate together. The scraper 53 will rotate along the inner wall of the pretreatment box 2. Thus, during the rotation of the scraper 53, the inner wall of the pretreatment box 2 can be cleaned to prevent the inner wall of the pretreatment box 2 from adhering to the raw materials. Therefore, through this device, not only the cleaning effect can be achieved, but also the reduction of raw materials can be prevented.

[0021] As Figures 1-2 and Figure 8As shown in the figure, in this embodiment, specifically, a filtering component 6 is provided above the pretreatment tank 2. The filtering component 6 includes a filtering pipe 61. A plurality of filter plates are installed inside the filtering pipe 61. A negative ion generator 62 is installed on the side of the pretreatment tank 2. The output end of the negative ion generator 62 is connected to the filtering pipe 61; Since plastics may produce a small amount of harmful gases when heated, when the pretreatment tank 2 of the device processes the material raw materials, it can also process the harmful gases, eliminate certain harmful gases, make the finally discharged gas meet the emission standards, and reduce the pollution to the external environment. During specific use, the negative ion generator 62 can generate negative ions and supply them into the filtering pipe 61. When the generated waste gas is discharged from the filtering pipe 61, it will first pass through a plurality of filter plates, thereby preliminarily filtering the gas. Then, during the discharge of the waste gas, part of it will combine with the negative ions, causing part of the waste gas to sink, thereby reducing the discharge of harmful gases.

[0022] As Figure 3 As shown in the figure, in this embodiment, specifically, a feeding component 7 is installed between the forming block 3 and the pretreatment tank 2. The feeding component 7 includes a feeding motor 71 and a feeding pipe 72. The feeding motor 71 is connected to one end of the feeding pipe 72. The other end of the feeding pipe 72 is connected to the forming block 3. A feeding screw 73 is installed inside the feeding pipe 72; After the pretreatment tank 2 of the device finishes the pretreatment of the raw materials, it will transport the raw materials through the feeding component 7 so that the raw materials can be provided into the forming block 3, so that the forming block 3 can inject the decorative strip. During specific use, when the raw materials enter the feeding pipe 72, since the feeding motor 71 can drive the feeding screw 73 to rotate, and due to the direction of the screw blades, the screw blades can drive the raw materials to move towards the discharge port when rotating, and then supply them into the forming block 3.

[0023] As Figure 4 As shown in the figure, in this embodiment, specifically, a forming groove 31 and two groups of cooling components 8 are provided inside the forming block 3. The cooling components 8 are arranged around the forming groove 31. The cooling components 8 include a circulation pipeline 81, a plurality of heat absorption plates 82 and a plurality of cooling plates 83. The circulation pipeline 81 is arranged between the plurality of heat absorption plates 82 and the cooling plates 83. The heat absorption plates 82 are installed at the input end of the forming groove 31. The cooling plates 83 are installed at the output end of the forming groove 31. The cooling plates 83 are connected to the heat absorption plates 82 through wires. The controller 11 is also connected to the cooling plates 83 and the heat absorption plates 82 through wires; The main function of the forming block 3 is to define the shape of the decorative strip. During specific use, when the raw material is supplied into the forming block 3 through the feeding component 7, the raw material will be injection-molded into a decorative strip following the shape of the forming groove 31. When the forming block 3 forms the raw material, the raw material will pass through the cooling component 8. The cooling component 8 can accelerate the forming of the raw material. When the cooling component 8 is in use, through an external water pump, the liquid can be continuously circulated in the circulation pipeline 81 to accelerate the forming of the decorative strip. At the same time, the heat absorption plate 82 of the device will absorb heat at the feeding port. Since the heat absorption plate 82 is connected to the cooling plate 83, the carrier electrons in the heat absorption plate 82 will move into the cooling plate 83, thereby generating a temperature difference between the heat absorption plate 82 and the cooling plate 83. Combined with the circulation pipeline 81, it can assist in forming the decorative strip faster.

[0024] As Figure 4 shown, in this embodiment, specifically, the cooling plate 83 and the heat absorption plate 82 are composed of metal plates and semiconductors of different materials. The heat absorption plate 82 is the hot end, and the cooling plate 83 is the cold end; Since the heat absorption plate 82 of the device is the hot end, it mainly absorbs heat through the heat absorption plate 82. Since the cooling plate 83 is the cold end, when the heat absorption plate 82 absorbs heat, the carrier electrons in the heat absorption plate 82 will move into the cooling plate 83 and accumulate in the cooling plate 83, thereby generating a temperature difference between the heat absorption plate 82 and the cooling plate 83. Since the controller 11 is connected to the heat absorption plate 82 and the cooling plate 83, the cooling component 8 can be detected in real time through control to make up for the cooling component 8.

[0025] As Figures 5-6 shown, in this embodiment, specifically, the grinding component 4 includes a support frame 41. A clamping component 9 is arranged at the bottom of the support frame 41. The clamping component 9 can clamp and limit the decorative strip. A grinding motor 42 is installed above the support frame 41. A transmission shaft 43 is installed at the output end of the grinding motor 42. Pulley wheels are respectively arranged at both ends of the transmission shaft 43. Two groups of limit blocks 44 are respectively installed at the lower edge of the support frame 41. A grinding wheel 45 is installed between the two groups of limit blocks 44. Pulley wheels are also installed at both ends of the grinding wheel 45. A belt is connected between the pulley wheels. The grinding wheel 45 can grind the decorative strip; When the grinding component 4 of the device is in use, it can grind the display surface and corners of the decorative strip, thereby reducing the particles and burrs on the display surface. Specifically, when the grinding motor 42 rotates, it can drive the pulley to rotate. At the same time, because a belt is installed between the pulleys, it can drive the grinding wheel 45 to rotate together. When the grinding wheel 45 grinds the decorative strip, the clamping component 9 can adjust the tightness of the decorative strip, and then cooperate with the grinding wheel 45 to more effectively polish and grind the decorative strip, so that when the decorative strip is painted later, the painting effect will not be affected by the uneven surface.

[0026] As Figure 5 shown, in this embodiment, specifically, the clamping component 9 includes two groups of limit frames 91. Clamping rollers 92 and clamping motors are respectively arranged on the two groups of limit frames 91. The clamping motor is connected to the clamping roller 92. One group of limit frames 91 is fixedly installed at the bottom of the support frame 41, and a driving plate 93 is installed at the bottom of the other group of limit frames 91. The driving plate 93 can slide at the bottom of the support frame 41; When the clamping component 9 of the device is in use, it can clamp the formed decorative strip and at the same time can also pull the decorative strip out. Specifically, when the formed decorative strip passes between the clamping rollers 92, the clamping motor will drive the clamping rollers 92 to rotate, and then can drive the decorative strip to move. Because one group of limit frames 91 is fixedly installed at the bottom of the support frame 41, and the other group of limit frames 91 can move back and forth at the bottom of the support frame 41, the un-fixed group of limit frames 91 can adjust the tightness of the decorative strip according to the state of the decorative strip.

[0027] As Figure 5 shown, in this embodiment, specifically, a driving groove is formed in the middle of the driving plate 93. A driving motor 94 is installed at the bottom of the support frame 41. A driving rod is installed at the output end of the driving motor 94. The driving rod is threadedly connected to the driving groove; When the movable limit frame 91 is in use, it is mainly driven by an external driving motor 94 to drive the driving rod to rotate. Because the driving rod is connected to the driving groove in the driving plate 93, and because the moving direction of the limit frame 91 is limited, when the driving motor 94 drives the driving rod to rotate, it can drive the limit frame 91 to move.

[0028] As Figure 1 shown, in this embodiment, specifically, a controller 11 is installed on the side of the injection molding equipment main body 1. A control platform is arranged on the controller 11; When the injection molding equipment main body 1 is in use, it can be controlled by the controller 11. At the same time, because a control platform is arranged on the controller 11, the staff can control the injection molding equipment main body 1 through the control panel on the controller 11.

[0029] Working principle: When this device is in use, the injection molding equipment main body 1 can perform injection molding on the decorative strips for vehicles. Specifically, during use, the pretreatment box 2 can process the raw materials. During the processing, the pretreatment box 2 can continuously heat the raw materials inside it so that the raw materials can melt. After the raw materials enter the forming block 3, they can be formed through the forming grooves 31 of the forming block 3. During the process of forming the decorative strips by the forming block 3, the cooling component 8 can also accelerate the forming of the decorative strips. After the formed decorative strips are discharged, the grinding component 4 can grind the outer surface and side surfaces of the decorative strips to remove the burrs on the decorative strips, so that when the decorative strips are spray-painted later, color differences on the decorative strips will not occur. At the same time, during the process of grinding the decorative strips, the clamping component 9 can tighten or loosen the decorative strips by itself, so that when the decorative strips are being ground, the situation that the decorative strips break due to excessive force can be prevented.
