Description

Technical Field

[0001] This utility model belongs to the field of automotive trim strip mold technology, and in particular relates to a precision machining mold for automotive trim strips. Background Technology

[0002] An automotive trim strip mold is a precision mold specifically designed for producing automotive trim strips. Manufactured using specific materials and processes, it boasts precise dimensions and shapes, ensuring that the produced trim strips meet design requirements. The mold typically consists of an upper and lower mold. Molten plastic material is injected into the mold cavity using injection molding, blow molding, or other molding processes, and after cooling and solidification, the automotive trim strip is formed. Automotive trim strip molds not only require high precision and high wear resistance but also excellent sealing and stability to ensure that the produced trim strips have a smooth surface, accurate dimensions, and reliable quality.

[0003] For example, Chinese patent CN219191132U discloses an automotive trim strip mold, belonging to the field of automotive trim strip molding technology. It mainly addresses the problem that existing automotive trim strip molding molds cannot cool the plastic, proposing the following technical solution: a bottom mold and a top mold, with the top of the bottom mold fitted and connected to it; a control switch is installed on the front of the bottom mold, and superconducting cooling chips are arranged inside the inner wall of the bottom mold.

[0004] The aforementioned patent has the following problems: in actual use, it does not have the function of demolding after molding, which will cause demolding difficulties, easy damage, low production efficiency, and aggravate mold wear, and may cause safety hazards, which is not conducive to the use of workers. In view of this, we propose a precision machining mold for automotive decorative strip mold. Utility Model Content

[0005] The purpose of this utility model is to provide a precision machining mold for automotive decorative strips to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a precision machining mold for automotive decorative strips, including a base, a lower mold and an upper mold. The lower mold is fixedly installed on the top of the base, and a fixing frame is fixedly connected to the top of the base. The fixing frame is 'n' shaped, and a motor is provided on the top of the fixing frame. A first threaded sleeve, the top of which is fixedly mounted on the output end of the motor, the bottom of which extends into the interior of the fixed frame, a first threaded rod is threadedly connected to the interior of the first threaded sleeve, a movable plate is fixedly connected to the bottom of the first threaded rod, and the upper mold is disposed at the bottom of the movable plate. The second threaded sleeve has its bottom rotatably mounted on the top of the base. The second threaded sleeve extends into the interior of the lower mold. The interior of the second threaded sleeve is threadedly connected to a second threaded rod, and the top of the second threaded rod is fixedly connected to a release plate. A rotating assembly is disposed on the top of the base and is used to drive the rotation of the second threaded sleeve.

[0007] In this technical solution, the production of automotive trim strip molds can be achieved through the setting of upper and lower molds. By starting the motor, the output end of the motor drives the first threaded sleeve to rotate, which in turn drives the first threaded rod, the moving plate, the upper mold, and the slider to move. At this time, the upper mold can be moved away from the lower mold, and the slider can slide outside the sliding rod, which makes the moving plate more stable when moving. With the above structure, the production and processing of automotive trim strip molds can be completed.

[0008] The rotation of the first threaded sleeve drives the rotating shaft to rotate, which in turn drives the second threaded sleeve to rotate. The rotation of the second threaded sleeve causes the second threaded rod and the demolding template to rise, thus ejecting the molded part and completing the demolding operation. When the demolding template moves, it causes the telescopic rod to slide inside the telescopic sleeve, preventing the demolding template from rotating during movement. With the above structure, the molded part can be demolded quickly, improving the mold cycle and production efficiency, and making it more convenient for operators to use.

[0009] In the above technical solution, the rotating assembly further includes a rotating shaft rotatably mounted on the top of the base, with a first synchronous wheel fixedly sleeved on the outside of the rotating shaft and the outside of the first threaded sleeve, and a second synchronous wheel fixedly sleeved on the outside of the rotating shaft and the outside of the second threaded sleeve.

[0010] In this technical solution, by using a first synchronous pulley and a first synchronous belt located outside the first threaded sleeve and the rotating shaft, the rotation of the first threaded sleeve can drive the rotating shaft to rotate. Similarly, by using a second synchronous pulley and a second synchronous belt located outside the rotating shaft and the second threaded sleeve, the rotation of the rotating shaft can drive the second threaded sleeve to rotate.

[0011] In the above technical solution, the two first synchronous pulleys are externally meshed with the same first synchronous belt, and the two second synchronous pulleys are externally meshed with the same second synchronous belt.

[0012] In this technical solution, two first synchronous pulleys can be connected by a first synchronous belt, and two second synchronous pulleys can be connected by a second synchronous belt.

[0013] In the above technical solution, a fixing plate is fixedly connected to one side of the fixing frame, and the rotating shaft is rotatably mounted on the fixing plate.

[0014] In this technical solution, the fixed plate makes the rotating shaft more stable when it rotates.

[0015] In the above technical solution, a support frame is further fixedly connected to the top of the fixed frame, and the motor is fixedly mounted on the support frame.

[0016] In this technical solution, the support frame prevents the motor from spinning idly during operation.

[0017] In the above technical solution, further, slide rods are fixedly connected to the top four corners of the base, and sliders are slidably installed on the outside of each of the four slide rods, and the outside of each of the four sliders is fixedly connected to the outside of the movable plate.

[0018] In this technical solution, by sliding the slider outside the slide bar, the moving plate can be made more stable when moving.

[0019] In the above technical solution, further, the top of the base is fixedly connected to two symmetrically distributed telescopic sleeves, and telescopic rods are slidably installed inside the two telescopic sleeves. The tops of the two telescopic rods are fixedly connected to the bottom of the template.

[0020] In this technical solution, when the demolding template moves, it causes the telescopic rod to slide inside the telescopic sleeve, which prevents the demolding template from rotating during movement.

[0021] The beneficial effects of this utility model are: 1. By setting up an upper and lower mold, the automotive trim strip mold can be produced. By starting the motor, the output end of the motor drives the first threaded sleeve to rotate, which in turn drives the first threaded rod, the moving plate, the upper mold and the slider to move. At this time, the upper mold can be moved away from the lower mold. By sliding the slider outside the slide rod, the moving plate can be made more stable when moving. With the above structure, the production and processing of the automotive trim strip mold can be completed.

[0022] 2. The rotation of the first threaded sleeve drives the rotating shaft to rotate, which in turn drives the second threaded sleeve to rotate. The rotation of the second threaded sleeve causes the second threaded rod and the demolding template to rise, thus ejecting the molded part and completing the demolding operation. When the demolding template moves, it causes the telescopic rod to slide inside the telescopic sleeve, preventing the demolding template from rotating during movement. With the above structure, the molded part can be demolded quickly, improving the mold cycle and production efficiency, and making it easier for operators to use. Attached Figure Description

[0030] Please see Figure 1 - Figure 4 As shown, this embodiment provides a precision machining mold for automotive trim strips, including a base 1, a lower mold 2 and an upper mold 6. The lower mold 2 is fixedly installed on the top of the base 1, and a fixing frame 7 is fixedly connected to the top of the base 1. The fixing frame 7 is 'n' shaped, and a motor 9 is provided on the top of the fixing frame 7. The first threaded sleeve 10 has its top fixedly mounted on the output end of the motor 9, and its bottom extends into the interior of the fixing frame 7. The first threaded sleeve 10 has a first threaded rod 11 threadedly connected inside, and a movable plate 5 is fixedly connected to the bottom of the first threaded rod 11. The upper mold 6 is located at the bottom of the movable plate 5. The second threaded sleeve 12 is rotatably mounted on the top of the base 1.

A rotating assembly is located on top of the base 1 and is used to drive the rotation of the second threaded sleeve 12.

[0031] The upper mold 6 and lower mold 2 are used to produce automotive trim strip molds. By starting the motor 9, the output end of the motor 9 drives the first threaded sleeve 10 to rotate, which in turn drives the first threaded rod 11, the moving plate 5, the upper mold 6 and the slider 4 to move. At this time, the upper mold 6 can be moved away from the lower mold 2, and the slider 4 slides outside the slide rod 3, which makes the moving plate 5 more stable when moving. With the above structure, the production and processing of automotive trim strip molds can be completed.

The rotation of the second threaded sleeve 12 causes the second threaded rod 13 and the demolding template 22 to rise, thus ejecting the molded part and completing the demolding operation. When the demolding template 22 moves, it causes the telescopic rod 15 to slide inside the telescopic sleeve 14, preventing the demolding template 22 from rotating during movement. With the above structure, the molded part can be demolded quickly, improving the mold cycle and production efficiency, and making it more convenient for workers to use. Example
