[0021] As an implementation manner in this embodiment, as Figure 1As shown in the figure, the downward movement mechanism includes a first cylinder 4, which is fixedly connected to the top end of the frame 1. The bottom end of the first cylinder 4 is fixedly connected with a fixed plate 401. Both the left and right side ends of the fixed plate 401 are fixedly connected with side plates 402. The bottom end of each side plate 402 is fixedly connected with a pressing rod 403. The downward pressing mechanism includes a second cylinder 5, which is fixedly connected to the bottom end of the fixed plate 401. The bottom end of the second cylinder 5 is fixedly connected with an upper mold 501. A heating wire is installed inside the upper mold 501. During implementation, after placing the material for manufacturing the car lamp into the lower mold 201, by starting the first cylinder 4 to drive the fixed plate 401 and the whole downward pressing mechanism to move downward, and by starting the second cylinder 5 to drive the upper mold 501 to move downward, and then by starting the heating wire to heat the upper mold 501, the upper mold 501 and the lower mold 201 can cooperate to heat and extrude the internal material, so as to form the workpiece required for car lamp production.

[0022] As an implementation manner in this embodiment, such as Figure 2 、 Figure 3 and Figure 4As shown in the figure, the ejector mechanism includes a first round rod 3, the first round rod 3 is fixedly connected to the bottom end of the frame 1, a first spring 301 is sleeved on the outer end of the first round rod 3, a limiting plate 302 is fixedly connected to the top end of the first round rod 3, a second round rod 303 is fixedly connected between the bottom end of the lower die 201 and the bottom end of the frame 1, a second spring 304 is sleeved on the outer end of the second round rod 303, a bent plate 305 is sleeved between the outer end of the first round rod 3 and the outer end of the second round rod 303, the bottom end of the first spring 301 is fixedly connected to the bottom end of the frame 1, and the top end of the first spring 301 is fixedly connected to the bottom end of the bent plate 305, which can make the installation of the first spring 301 more stable. The bottom end of the second spring 304 is fixedly connected to the bottom end of the frame 1, and the top end of the second spring 304 is fixedly connected to the bottom end of the bent plate 305, which can make the installation of the second spring 304 more stable. A straight rod 306 is fixedly connected to the top end of the bent plate 305, a push plate 307 is fixedly connected to the top end of the straight rod 306, and the shape of the bent plate 305 is set in a Z shape, which is convenient for adapting to the shape of the lower die 201. The straight rod 306 is inserted into the notch 202, and the push plate 307 is located inside the lower die 201, which is convenient for pushing the workpiece to be discharged. During implementation, when it is necessary to strip and discharge the workpiece, the upper die 501 is driven to move upward by starting the second cylinder 5. At this time, the fixed plate 401, the pressing rod 403 and the upper die 501 are driven to move upward by starting the first cylinder 4. At this time, if there is an undischarged workpiece at the outer end of the upper die 501, when the workpiece passes through the bottom end of the scraper 101 and the upper die 501 continues to move upward, the scraper 101 can push the workpiece from the outer end of the upper die 501 for discharging. If there is an undischarged workpiece inside the lower die 201, when the pressing rod 403 continues to move upward until it no longer presses against the bent plate 305, the first spring 301 and the second spring 304 will push the bent plate 305 upward and drive the straight rod 306 and the push plate 307 upward, so as to eject the workpiece in the lower die 201. Therefore, through the setting of this device, no matter whether the workpiece is tightly connected to the upper die 501 or the lower die 201, it is convenient to discharge the workpiece, and it is not necessary to wait until the workpiece is completely cooled to facilitate discharging, and it can also avoid scalding the staff, and at the same time improve the production efficiency of the car lamp workpiece.

[0023] Working principle: After placing the material for manufacturing the vehicle lamp inside the lower die 201, start the first cylinder 4 to drive the fixing plate 401 and the entire pressing mechanism to move downward. At this time, since the bottom of the pressure rod 403 is lower than the bottom end of the upper die 501, the pressure rod 403 first abuts against the top of each bent plate 305 after moving downward. When the first cylinder 4 continuously drives the fixing plate 401 and the pressure rod 403 to move downward, the pressure rod 403 can press the bent plate 305 to move downward. At this time, the bent plate 305 will press the first spring 301 and the second spring 304 to contract. At this time, the downward movement of the bent plate 305 drives the straight rod 306 and the push plate 307 to move downward. At this time, the push plate 307 can be located in the notch 202 and flush with the bottom of the lower die 201. At this time, a part of the upper die 501 enters the lower die 201. By starting the second cylinder 5 to drive the upper die 501 to move downward and then starting the heating wire to heat the upper die 501, the upper die 501 and the lower die 201 can cooperate to heat and extrude the internal material, so as to form the workpiece required for vehicle lamp manufacturing. When it is necessary to strip and unload the workpiece, start the second cylinder 5 to drive the upper die 501 to move upward. At this time, start the first cylinder 4 to drive the fixing plate 401, the pressure rod 403 and the upper die 501 to move upward. At this time, if there is an unloaded workpiece at the outer end of the upper die 501, when the workpiece passes through the bottom end of the scraping plate 101 and the upper die 501 continues to move upward, the scraping plate 101 can push the workpiece from the outer end of the upper die 501 for unloading. If there is an unloaded workpiece inside the lower die 201, when the pressure rod 403 continues to move upward until it no longer abuts against the bent plate 305, the first spring 301 and the second spring 304 will push the bent plate 305 upward and drive the straight rod 306 and the push plate 307 upward, so as to eject the workpiece inside the lower die 201. Therefore, through the setting of this device, no matter whether the workpiece is tightly connected to the upper die 501 or the lower die 201, it is convenient to unload the workpiece. It is not necessary to wait until the workpiece is completely cooled to facilitate unloading, and it can also avoid scalding the staff. At the same time, the efficiency of manufacturing the vehicle lamp workpiece is improved.
