Description

Technical Field

[0001] This utility model relates to the field of PC board production technology, specifically a PC board steel mold with a high-efficiency demolding structure. Background Technology

[0002] PC sheets are characterized by good light transmittance, high impact resistance, and light weight, and are widely used in construction, transportation, electronics, and other fields. During the production of PC sheets, steel molds are required for auxiliary operations, and the demolding process after molding directly affects production efficiency and product quality.

[0003] The prior art CN223173403U discloses a plastic cup lid molding device that facilitates demolding and prevents sticking, including a fixed plate, a support column and a support rod. A molding mold is fixedly connected to the top of the fixed plate, and an anti-overflow frame is fixedly connected to the outside of the molding mold. A cooling cavity is fixedly connected to the bottom of the anti-overflow frame. By setting a demolding component, the ejector plate welded to the top of the telescopic component ejects the plastic cup lid, which facilitates demolding of the molding device and avoids sticking during demolding.

[0004] However, the following shortcomings still exist in actual use: the injection molded part is lifted by the ejector plate, and it still needs to be manually removed after being lifted. Manual removal is not only inefficient, but also requires operators to be in close contact with the steel mold, which can easily cause burns, squeezing and other safety accidents due to the residual heat of the steel mold or accidental triggering of the equipment, resulting in poor safety.

[0005] Based on this, a PC board steel mold with a highly efficient demolding structure is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] In one embodiment, such as Figures 1-3 As shown, a PC board steel mold with a high-efficiency demolding structure includes a fixed plate 100. A support rod 101 is fixedly connected to the upper end of the fixed plate 100. A top plate 102 is fixedly connected to the upper end of the support rod 101. A fixed mold 201 is provided on the fixed plate 100. A telescopic rod 202 is fixedly connected to the upper end of the top plate 102. A movable plate 203 is fixedly connected to the output rod of the telescopic rod 202. The movable plate 203 is slidably connected to a limiting rod 204, which is fixedly connected to the fixed plate 100. A movable mold 205 is fixedly connected to the lower end of the movable plate 203. The lower end of the fixed plate 100 is connected to a support rod 205. 103 connects to the base plate 104. The lower end of the fixed plate 100 is provided with an ejection mechanism, which is connected to a transmission component. The side of the fixed plate 100 is provided with a pushing unit. The moving plate 203 is driven to move downward along the limiting rod 204 by the telescopic rod 202, so as to realize the mold closing of the moving mold 205 and the fixed mold 201. After the PC board is cooled and formed, the telescopic rod 202 retracts the output rod, pulls the moving plate 203 to reset upward along the limiting rod 204, and drives the moving mold 205 to separate from the fixed mold 201. The ejection mechanism lifts the formed PC board from the cavity, so that it is separated from the surface of the fixed mold. The pushing unit pushes the ejected PC board away from the fixed mold area.

[0022] In this embodiment, as Figure 1 and Figure 2 As shown, the ejection mechanism includes an ejection plate 301. Four guide rods 302 are fixedly connected to the upper end of the ejection plate 301. The guide rods 302 are slidably connected to the fixed plate 100. A spring 303 is provided at the outer end of the guide rod 302. The two ends of the spring 303 are respectively connected to the lower end of the ejection plate 301 and the fixed plate 100. An ejection pin 304 is fixedly connected to the upper end of the ejection plate 301. The ejection pin 304 extends into the fixed mold 201. The transmission component drives the ejection plate 301 to move upward against the elastic force of the spring 303. The ejection pin 304 on the ejection plate 301 rises synchronously and extends out of the fixed mold 201, lifting the formed PC board from the cavity and making it separate from the surface of the fixed mold.

[0023] In one embodiment, such as Figure 1 and Figure 3 As shown, the transmission component includes a guide rail 401, which is fixedly connected to the base plate 104. A slider 402 is slidably connected to the guide rail 401. Support plates 403 are fixedly connected to both sides of the slider 402. The support plates 403 are provided with two guide grooves 404. A moving rod 405 is slidably connected in the guide grooves 404. The moving rod 405 is connected to the ejector plate 301 through a connecting rod 406. A moving wheel 409 is rotatably connected to the moving rod 405. The slider 402 is provided with a protrusion corresponding to the trajectory of the guide grooves 404. Block 407, the movable wheel 409 contacts the protrusion 407, the slider 402 is fixedly connected to the output rod of the telescopic rod 408, the telescopic rod 408 is fixedly connected to the base plate 104, the telescopic rod 408 extends out of the output rod, pushes the slider 402 to slide along the guide rail 401, the protrusion 407 on the slider 402 moves with the slider, contacts the movable wheel 409 on the movable rod 405, and cooperates with the guide groove 404, pushes the movable rod 405 to move upward, thereby driving the ejector plate 301 to move upward, and lifts the formed PC board from the cavity.

[0024] In one embodiment, such as Figure 1 and Figure 2As shown, the pushing unit includes a push rod 501, which is fixedly connected to a slider 402. The push rod 501 is fixedly connected to a piston 502, which is slidably connected to a piston cylinder 503. The piston cylinder 503 is connected to a piston cylinder 504 via an air pipe. The piston cylinder 504 is fixedly connected to a fixed plate 100. A piston 505 is slidably connected to the piston cylinder 504, and the piston 505 is fixedly connected to the push rod 402. The second moving rod 506 is fixedly connected to the push plate 507. When the slider 402 moves, it drives the first pushing rod 501 to move synchronously. The first pushing rod 501 drives the first piston 502 to move into the first piston cylinder 503, squeezing the gas in the first piston cylinder 503 into the second piston cylinder 504, pushing the second piston 505 to move outward, driving the second pushing rod 506 to move. The second pushing rod 506 drives the push plate 507 to move, pushing the lifted PC plate away from the fixed mold area.

[0025] In one embodiment, such as Figure 2 As shown, the fixed mold 201 is provided with a sealing ring 600 at its upper end. When the moving mold 205 and the fixed mold 201 are closed, the sealing ring 600 can fill the tiny gap between them to form a tight sealing structure, which effectively prevents the molten PC material from overflowing from the mold gap and avoids material waste.

[0026] In one embodiment, such as Figure 1 As shown, the fixed plate 100 is provided with a guide plate 700 on the side away from the pushing unit, which can receive the pushed PC board and guide it to slide slowly towards the collection area through the inclined surface, effectively buffering the falling impact, protecting the product's appearance and structural integrity, and reducing the scrap rate.

[0027] In one embodiment, such as Figure 1 As shown, the upper end of the fixed plate 100 is fixedly connected to the controller 800. The controller 800 is electrically connected to the telescopic rod 202 and the telescopic rod 408 respectively. The controller 800 can be preset with a program to precisely control the movement rhythm of the telescopic rod 202 and the telescopic rod 408 in a logical sequence.

[0028] In one embodiment, such as Figure 1 As shown, the four guide rods 302 are evenly distributed on the fixed plate 100. When the ejector plate 301 lifts the formed PC plate through the ejector pin 304, the four evenly distributed guide rods can provide stable support to the ejector plate from different directions.

[0029] The above embodiment discloses a PC board steel mold with a high-efficiency demolding structure. The moving plate 203 is driven downwards along the limiting rod 204 by a telescopic rod 202, achieving mold closing between the moving mold 205 and the fixed mold 201. After the PC board cools and solidifies, the telescopic rod 202 retracts its output rod, pulling the moving plate 203 upwards along the limiting rod 204 to reset, causing the moving mold 205 to separate from the fixed mold 201. The telescopic rod 408 extends its output rod, pushing the slider 402 to slide along the guide rail 401. The protrusion 407 on the slider 402 moves with the slider, contacting the moving wheel 409 on the moving rod 405 and cooperating with the guide groove 404 to push the moving plate 205... The moving rod 405 moves upward, thereby driving the ejector plate 301 to move upward. The ejector pins 304 on the ejector plate 301 rise synchronously and extend out of the fixed mold 201, lifting the formed PC plate from the cavity and making it separate from the surface of the fixed mold. At the same time as the slider 402 moves, it drives the push rod 501 to move synchronously. The push rod 501 drives the piston 502 to move into the piston cylinder 503, squeezing the gas in the piston cylinder 503 into the piston cylinder 504, pushing the piston 505 to move outward, driving the push rod 506 to move. The push rod 506 drives the push plate 507 to move, pushing the lifted PC plate away from the fixed mold area.

[0030] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
