Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a long-life injection mold for a car headlight bracket. Background Technology

[0002] In modern automotive manufacturing, headlights, as a crucial component of vehicles, not only fulfill the key functions of illumination and signal indication but also directly impact the vehicle's appearance design and driving safety. Therefore, the manufacturing quality and precision requirements for headlight components are extremely high. Injection molding, as one of the main production processes for headlight brackets, directly determines the quality of the final product through the design and manufacturing level of its molds.

[0003] Injection molds are the core tool in the production process of automotive headlight brackets. They are used to inject molten plastic into the mold cavity, which then cools and solidifies to form the headlight bracket of the desired shape. However, in actual production, residual plastic on the mold has become a problem that urgently needs to be solved. This residual plastic mainly comes from overflow, flash, and tiny gaps on the mold parting surface during the injection molding process. It gradually accumulates during continuous production, leading to contamination of the mold surface.

[0004] The existing solution involves using a handheld high-pressure air gun to blow and clean the mold cavity, but this has the following problems in actual operation:

[0005] Manually holding a high-pressure air gun requires the operator to constantly move the air gun to ensure that every corner of the mold cavity is thoroughly flushed, which greatly increases the complexity and workload of the operation and reduces work efficiency.

[0006] High-pressure airflow and flying plastic fragments can cause damage to the operator's eyes and skin; at the same time, holding a high-pressure air gun for a long time can easily lead to muscle fatigue and strain. Utility Model Content

[0007] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0008] Specifically, the technical problem to be solved by this utility model is to provide a long-life injection mold for a car headlight bracket, so as to solve the technical problem of using a handheld high-pressure air gun to blow and clean the mold cavity.

[0009] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0010] A long-life injection mold for a car headlight bracket includes a mold and a cleaning component installed on the side of the mold. The cleaning component is used to clean the mold cavity. The mold is composed of an upper mold base and a lower mold base arranged opposite to each other.

[0011] The cleaning assembly includes a horizontal plate fixed to one side of the upper mold base, a sliding plate slidably mounted on the horizontal plate, a reciprocating structure fixed to the top of the sliding plate, two pipe supports fixed to the movable end of the reciprocating structure, an air jet pipe fixed between the two pipe supports, a row of high-pressure nozzles fixed to the upper and lower surfaces of the air jet pipe, a fan fixed to the top of the horizontal plate, and a hose installed between the air outlet of the fan and the air inlet of the air jet pipe.

[0012] As an improved technical solution, two linear motors are fixed to the top of the horizontal plate, and the translation plate is fixed between the movable ends of the two linear motors.

[0013] As an improved technical solution, the reciprocating structure includes a reciprocating plate slidably disposed on the top of the reciprocating structure, with sliding plates welded to both sides of the bottom of the reciprocating plate, and drive motors fixed to both sides of the top of the reciprocating structure, with a cam plate fixedly connected to the drive end of the drive motor.

[0014] As an improved technical solution, the reciprocating structure has rods welded to both sides of its top, a guide rod fixed between the two rods, and a sliding hole for the guide rod to pass through on the slide plate.

[0015] As an improved technical solution, springs are fitted on both the guide rod and the opposite surfaces of the rod frame and the slide plate, and the number of springs is two.

[0016] As an improved technical solution, the tube rack is L-shaped, and the end of the tube rack away from the translation plate has a tube hole for the jet pipe to pass through.

[0017] After adopting the above technical solution, the beneficial effects of this utility model are:

[0018] 1. In this utility model, the jet pipe enters between the opposing surfaces of the upper and lower mold bases, and the high-pressure nozzles on both the upper and lower mold bases simultaneously clean the mold cavities. When the linear motor drives the translation plate to move away from the mold, it causes the high-pressure nozzles to disengage from the upper and lower mold bases and reset. During the reset process, the high-pressure nozzles also clean the mold cavity again. This double cleaning helps improve the cleanliness of the mold cavity. While the high-pressure nozzles are cleaning the mold cavity, the reciprocating structure drives the tube frame to move back and forth, keeping the high-pressure nozzles in a position... The repeated back-and-forth movement disrupts the air outlets of the high-pressure nozzles, reducing blind spots in the cleaning of the mold cavity and improving the cleaning effect. A linear motor drives the high-pressure nozzles into the mold cavity for high-pressure air cleaning, eliminating the need for manual hand-held operation. This not only improves work efficiency but also prevents injury to the operator's eyes and skin from high-pressure airflow and splashing plastic fragments. Furthermore, the high-pressure airflow provides comprehensive cleaning of the mold cavity, ensuring effective cleaning, maintaining mold precision, and extending mold lifespan.

[0029] like Figures 1 to 3 As shown in the figure, this embodiment provides a long-life injection mold for a car headlight bracket. This long-life injection mold for a car headlight bracket includes a mold 1 and a cleaning component 2 installed on the side of the mold 1. The cleaning component 2 is used to clean the mold cavity of the mold 1. The mold 1 is composed of an upper mold base 11 and a lower mold base 12 arranged opposite to each other. The upper mold base 11 and the lower mold base 12 are both existing mature technologies, so they will not be described in detail.

[0030] The cleaning component 2 includes a horizontal plate 21 fixed to one side of the upper mold base 11. A translation plate 23 is slidably mounted on the horizontal plate 21. A reciprocating structure 24 is fixed to the top of the translation plate 23. Two tube supports 25 are fixed at the movable end of the reciprocating structure 24. An air jet pipe 29 is fixed between the two tube supports 25. A row of high-pressure nozzles 28 is fixed on both the upper and lower surfaces of the air jet pipe 29. The high-pressure nozzles 28 on the upper and lower mold base 11 and the lower mold base 12 are cleaned simultaneously through the upper and lower high-pressure nozzles 28. A fan 26 is fixed to the top of the horizontal plate 21. A hose 27 is installed between the air outlet of the fan 26 and the air inlet of the air jet pipe 29.

[0031] A linear motor 22 drives a high-pressure nozzle 28 to enter the mold cavity and perform high-pressure air blowing for cleaning. This eliminates the need for manual hand operation, improving work efficiency and preventing damage to the operator's eyes and skin from high-pressure airflow and splashing plastic fragments. Furthermore, the high-pressure airflow can clean the mold cavity from all angles, ensuring a thorough cleaning effect, thus guaranteeing the mold's precision and extending its service life.

[0032] like Figures 1 to 2 As shown in the figure, in this embodiment, two linear motors 22 are fixed to the top of the horizontal plate 21, and the translation plate 23 is fixed between the movable ends of the two linear motors 22. As the linear motors 22 continuously drive the translation plate 23 to move towards the mold 1, the high-pressure nozzle 28 moves along the mold cavity, expanding the area of ​​the high-pressure nozzle 28 to clean the mold cavity, thereby performing a comprehensive cleaning operation on the mold cavity. When the linear motors 22 drive the translation plate 23 to move away from the mold 1, the high-pressure nozzle 28 is driven to disengage from the upper mold base 11 and the lower mold base 12 and reset. During the reset process of the high-pressure nozzle 28, the high-pressure nozzle 28 will also clean the mold cavity again. The two cleanings help to improve the cleanliness of the mold cavity.

[0033] like Figures 2 to 3 As shown in the figure, in this embodiment, the reciprocating structure 24 includes a reciprocating plate 246 slidably disposed on the top of the reciprocating structure 24, and a tube frame 25 is welded on the reciprocating plate 246. Slide plates 243 are welded on both sides of the bottom of the reciprocating plate 246. Drive motors 247 are fixed on both sides of the top of the reciprocating structure 24, and a cam plate 244 is fixedly connected to the drive end of the drive motor 247.

[0034] like Figure 3 As shown, in this embodiment, rods 241 are welded to both sides of the top of the reciprocating structure 24, a guide rod 245 is fixed between the two rods 241, and a sliding hole is provided on the slide plate 243 for the guide rod 245 to pass through.

[0035] like Figure 3 As shown, in this embodiment, springs 242 are fitted on the guide rod 245 and between the opposing surfaces of the rod frame 241 and the slide plate 243, and there are two springs 242.

[0036] When the high-pressure nozzle 28 cleans the mold cavity, the reciprocating structure 24 drives the tube frame 25 to move back and forth, so that the high-pressure nozzle 28 is in a back-and-forth reciprocating motion, which disrupts the air outlet of the high-pressure nozzle 28, thereby reducing the dead angles of the high-pressure nozzle 28 in cleaning the mold cavity, and thus improving the cleaning effect of the high-pressure nozzle 28 on the mold cavity.

[0037] like Figure 2As shown, in this embodiment, the tube rack 25 is L-shaped, and the end of the tube rack 25 away from the translation plate 23 has a tube hole for the jet pipe 29 to pass through.

[0038] During use, after injection molding is completed and the upper mold base 11 and lower mold base 12 are separated, the cleaning component 2 cleans the mold cavities of the upper mold base 11 and lower mold base 12. The process is as follows: the blower 26 is turned on and airflow is continuously delivered to the inside of the air jet pipe 29 through the hose 27. The airflow is blown out through the high-pressure nozzle 28. At the same time, the linear motor 22 drives the translation plate 23 to move towards the upper mold base 11, so that the air jet pipe 29 enters between the opposite surfaces of the upper mold base 11 and lower mold base 12. The high-pressure nozzles 28 set at the top and bottom clean the mold cavities on the upper mold base 11 and lower mold base 12 at the same time.

[0039] As the linear motor 22 continuously drives the translation plate 23 to move towards the mold 1, the high-pressure nozzle 28 travels along the mold cavity to perform a comprehensive cleaning operation on the mold cavity.

[0040] The drive motor 247 drives the cam plate 244 to rotate at high frequency. During the rotation of the cam plate 244, it will press the slide plate 243 towards the rod 241, which will drive the reciprocating plate 246 to move towards the rod 241 and compress the spring 242. When the cam plate 244 releases the pressure on the slide plate 243, the reciprocating plate 246 will be reset under the elastic reset of the spring 242. Therefore, in the rotating state of the cam plate 244, the reciprocating plate 246 is driven to move back and forth, so that the high-pressure nozzle 28 is in the back and forth reciprocating motion, which disrupts the air outlet of the high-pressure nozzle 28.

[0041] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
