Description

Technical Field

[0001] The utility model relates to a mould, in particular to an inclined ejection mould of a lamp panel, belonging to the technical field of moulds. Background Art

[0002] The lamp panel is the mounting plate of the car headlights and is a key component in the production of headlights. With the increase in the scale of vehicle production, the production of lamp panels has gradually become standardized and scaled. Under this production model, molds have become an irreplaceable task.

[0003] For example, the existing patent application number is: CN201110412074.2. The present invention proposes an injection mold, which includes a fixed mold plate and a movable mold plate. A core pulling mechanism is provided on the movable mold plate, a locking member is provided on the outer side of the fixed mold plate, and a locking member fixing seat is provided on the movable mold plate in connection with the core pulling mechanism. One end of the locking member is connected to the fixed mold plate, and the other end thereof forms a movable connection with the locking member fixing seat. Moreover, when the injection mold is in a mold closing state, the locking member and the locking member fixing seat are in a connected state, which can prevent the core pulling mechanism from being knocked back due to excessive injection force during the injection molding process. Since the locking member is provided on the outer side of the fixed mold plate, the setting of the locking member is not limited by the internal space of the mold, which can solve the problem that the locking mechanism is difficult to connect due to the limitation of the setting space. At the same time, it can also save space inside the mold.

[0004] The molds used in the factory are generally equipped with push rods and cylinders on the movable mold side to automatically demold the mold. Due to the requirements of lamp panel products, it is necessary to form inclined plates, barbs, clips, etc. on the lamp panel. At this time, the mold cannot be formed in one time and needs to be completed through secondary processing, which is costly. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The purpose of the utility model is to provide an inclined ejection mold for a lamp panel in order to solve the above-mentioned problem, so as to solve the problem in the prior art that when an inclined plate, a barb and a snap-in part are formed on the lamp panel, the mold cannot be formed in one step and secondary processing is required to complete the production of the product, which results in high cost.

[0007] (II) Technical solution

[0008] The utility model is realized through the following technical scheme: the oblique ejection mold of the lamp panel comprises a processing platform, an upper mold and a lower mold, and special-shaped shaping cavities are opened on both sides inside the lower mold, and a forming block is arranged inside the special-shaped shaping cavity, and a supporting structure is fixedly connected on both sides of the forming block, and the supporting structure obliquely penetrates the lower mold and the processing platform, and a supporting circular plate is arranged at the bottom of the processing platform, and a plurality of reset springs are fixedly connected between the bottom of the supporting circular plate and the bottom of the processing platform.

[0009] Preferably, a telescopic pneumatic cylinder is fixedly connected to the top of the upper mold, and a sealing block is fixedly connected to the bottom of the upper mold.

[0010] Preferably, an injection port is provided at the top of the upper mold, and a regular shaping cavity is provided at the bottom of the upper mold.

[0011] Preferably, a square support beam is fixedly connected to the bottom of the processing platform. The square support beam whose bottom end passes through the supporting circular plate limits the movement of the supporting circular plate so that the supporting circular plate can only move up and down, thereby ensuring the stability of the force on the supporting structure. The bottom end of the square support beam passes through the supporting circular plate.

[0012] Preferably, the bottom end of the square support beam is fixedly connected to a limiting plate, which limits the downward position of the supporting circular plate to prevent the supporting circular plate from separating from the limiting plate and controls the movement trajectory of the supporting circular plate. The top of the supporting circular plate is fixedly connected to a limiting ring, which blocks and limits the bottom of the supporting structure to prevent the bottom of the supporting structure from leaving the top of the supporting circular plate, causing the supporting circular plate to be unable to reset.

[0013] Preferably, the supporting structure includes a supporting inclined plate, which is fixedly connected to the forming block, and both ends of the supporting inclined plate are fixedly connected with a curved block and a supporting ball, respectively. The curved block contacts the upper mold or the sealing block, thereby reducing the wear on the supporting inclined plate when the upper mold and the sealing block move downward to push the supporting inclined plate to reset, thereby ensuring the smoothness of the bottom of the upper mold and the lower mold. The supporting ball is arranged on the top of the supporting circular plate, and the supporting ball reduces the friction force on the supporting circular plate, while applying the upward force applied by the supporting circular plate to the supporting inclined plate, so that the supporting inclined plate tilts and moves upward.

[0014] Preferably, both the top of the lower mold and the top of the processing platform are provided with installation bevel grooves, and the support bevel plate passes through the two installation bevel grooves. When the support bevel plate is tilted, the movement trajectory of the support bevel plate is restricted by the processing platform and the lower mold.

[0015] The utility model provides an inclined ejection mold for a lamp panel, which has the following beneficial effects:

[0016] 1. The lamp panel is inclinedly ejected from the mold, and the telescopic pneumatic cylinder is controlled to work to drive the upper mold and the lower mold to move upward. The molding block and the top of the supporting structure lose support. A plurality of reset springs are fixedly connected between the supporting circular plate arranged at the bottom of the supporting structure and the bottom of the processing platform. The plurality of reset springs rebound and drive the supporting circular plate to move upward. The upwardly moved supporting circular plate pushes the inclined supporting structure to move upward, so that the molding block moves upward and pushes the lamp panel with the barb out of the lower mold, completing the mold opening and the blanking of the lamp panel, achieving the one-time molding effect of the lamp panel with a special-shaped structure, and improving the processing efficiency.

[0017] 2. The lamp panel is inclinedly ejected from the mold, and the sealing block blocks and limits the forming block, and seals one side of the special-shaped molding cavity to prevent the raw material from entering the lower mold. The regular molding cavity opened at the bottom of the upper mold is set at the top of the special-shaped molding cavity, so it is far away from entering the regular molding cavity and the special-shaped molding cavity. After cooling, the raw material becomes a lamp panel with a barb at the bottom under the shaping of the regular molding cavity, the special-shaped molding cavity and the forming block.

[0024] The embodiment of the utility model provides an oblique ejection mold for a lamp panel.

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4, including a processing platform 1, an upper mold 7 and a lower mold 11, a telescopic pneumatic cylinder 9 is fixedly connected to the top of the upper mold 7, a sealing block 17 is fixedly connected to the bottom of the upper mold 7, an injection port 8 is opened at the top of the upper mold 7, a regular shaping cavity 10 is opened at the bottom of the upper mold 7, and special-shaped shaping cavities 12 are opened on both sides of the lower mold 11, and a forming block 13 is arranged inside the special-shaped shaping cavity 12. A supporting structure is fixedly connected to both sides of the forming block 13, and the supporting structure obliquely penetrates the lower mold 11 and the processing platform 1. The supporting structure includes a supporting inclined plate 14, and the supporting inclined plate 14 is fixedly connected to the forming block 13. The two ends of the supporting inclined plate 14 are respectively fixedly connected with a curved surface block 15 and a supporting ball 16, and the curved surface block 15 contacts with the upper mold 7 or the sealing block 17, so as to reduce the wear of the upper mold 7 and the sealing block 17 when the upper mold 7 and the sealing block 17 move downward to push the supporting inclined plate 14 to reset, thereby ensuring the smoothness of the bottom of the upper mold 7 and the lower mold 11. , the supporting ball 16 is arranged on the top of the supporting circular plate 4, and the supporting ball 16 reduces the friction force exerted on the supporting circular plate 4. At the same time, the upward moving force exerted by the supporting circular plate 4 is applied to the supporting inclined plate 14, so that the supporting inclined plate 14 is tilted and moved upward. A supporting circular plate 4 is arranged at the bottom of the processing platform 1, and a plurality of reset springs 6 are fixedly connected between the bottom of the supporting circular plate 4 and the bottom of the processing platform 1. A square supporting beam 2 is fixedly connected to the bottom of the processing platform 1, and the square supporting beam 2 whose bottom end passes through the supporting circular plate 4 limits the movement of the supporting circular plate 4, so that the supporting circular plate 4 can only move up and down, ensuring the stability of the force of the supporting structure. The bottom end of the square supporting beam 2 passes through the supporting circular plate 4, and the bottom end of the square supporting beam 2 is fixedly connected to the limiting plate 3, and the top of the supporting circular plate 4 is fixedly connected to the limiting ring 5. The limiting ring 5 blocks and limits the bottom of the supporting structure to avoid the situation that the supporting circular plate 4 cannot be reset due to the bottom of the supporting structure leaving the top of the supporting circular plate 4.

[0026] When the utility model is in use: the lower mold 11 fixed on the top of the processing platform 1 is a fixed mold, and the upper mold 7 fixedly connected to the top with a telescopic pneumatic cylinder 9 is a movable mold. The processing platform 1 and the telescopic pneumatic cylinder 9 are fixedly installed together with the equipment, bracket or cavity. By controlling the telescopic pneumatic cylinder 9 to work, the upper and lower positions of the upper mold 7 fixed at the bottom of the telescopic pneumatic cylinder 9 can be controlled. When the upper mold 7 moves to the bottom of the lower mold 11 and is tightly attached to the lower mold 11, the sealing block 17 fixedly connected to the bottom of the upper mold 7 enters the lower mold 11. Special-shaped shaping cavities 12 are provided on both sides of the lower mold 11, and a movable molding block 13 is provided inside the special-shaped shaping cavity 12. At this time, the sealing block 17 blocks and limits the molding block 13, and seals one side of the special-shaped shaping cavity 12 to prevent the raw material from entering the lower mold 11. At this time, the upper mold 7 and the lower mold 11 are in a mold closing state, such as Figure 1 shown.

[0027] After the raw material is injected into the injection port 8 opened at the top of the upper mold 7, since the regular shaping cavity 10 opened at the bottom of the upper mold 7 is set on the top of the special-shaped shaping cavity 12 at this time, the raw material enters the regular shaping cavity 10 and the special-shaped shaping cavity 12 away from the regular shaping cavity 10. After cooling, the raw material is shaped by the regular shaping cavity 10, the special-shaped shaping cavity 12 and the forming block 13 to become a lamp plate with a barb on the bottom.

[0028] After the lamp panel is formed, the telescopic pneumatic cylinder 9 is controlled to work and drive the upper mold 7 and the lower mold 11 to move upward, so that the upper mold 7 is away from the lower mold 11, and the supporting structures fixedly connected on both sides of the forming block 13 are tilted to penetrate the lower mold 11 and the processing platform 1. At this time, the forming block 13 and the top of the supporting structure lose support, and a plurality of reset springs 6 are fixedly connected between the supporting circular plate 4 set at the bottom of the supporting structure and the bottom of the processing platform 1. The plurality of reset springs 6 rebound and drive the supporting circular plate 4 to move upward. The upwardly moved supporting circular plate 4 pushes the tilted supporting structure to move upward, so that the forming block 13 moves upward to push the lamp panel with the barb out of the lower mold 11, complete the mold opening and the unloading of the lamp panel, and achieve the one-time molding effect of the lamp panel with a special-shaped structure, thereby improving the processing efficiency.

[0029] A square support beam 2 is fixedly connected to the bottom of the processing platform 1. The square support beam 2, which passes through the support circular plate 4 at the bottom, limits the movement of the support circular plate 4, so that the support circular plate 4 can only move up and down, ensuring the stability of the force of the support structure. A limit plate 3 is fixedly connected to the bottom of the square support beam 2. The limit plate 3 limits the downward position of the support circular plate 4 to prevent the support circular plate 4 from separating from the limit plate 3, control the movement trajectory of the support circular plate 4, and ensure the stability of the support circular plate 4. A limit ring 5 is fixedly connected to the top of the support circular plate 4. The limit ring 5 blocks and limits the bottom of the support structure to prevent the bottom of the support structure from leaving the top of the support circular plate 4, resulting in the inability of the support circular plate 4 to reset, thereby improving the stability of the cooperation between the support circular plate 4 and the support structure.

[0030] The supporting inclined plate 14 in the supporting structure is fixedly connected to the forming block 13, and the two ends of the supporting inclined plate 14 are respectively fixedly connected with a curved block 15 and a supporting ball 16. The supporting ball 16 is arranged on the top of the supporting circular plate 4. The supporting ball 16 reduces the friction force on the supporting circular plate 4 and at the same time, acts the upward force applied by the supporting circular plate 4 on the supporting inclined plate 14, so that the supporting inclined plate 14 tilts and moves upward. The curved block 15 on the top of the upwardly moved supporting inclined plate 14 contacts the upper mold 7 or the sealing block 17, reducing the wear of the upper mold 7 and the sealing block 17 when they move downward to push the supporting inclined plate 14 to reset, thereby ensuring the smoothness of the bottom of the upper mold 7 and the lower mold 11.

[0031] Mounting bevel grooves 18 are provided at the top of the lower mold 11 and the top of the processing platform 1 , and one end of the support bevel plate 14 passes through the two mounting bevel grooves 18 , so that the support bevel plate 14 is tilted while its movement trajectory is restricted by the processing platform 1 and the lower mold 11 .
