Description

Technical Field

[0001] This utility model relates to the field of panel-type molding die, and in particular to a panel-type molding die that is easy to demold. Background Technology

[0002] Panel-type molding molds are specialized molds used in molding processes. They are mainly used for the packaging of electronic components, LEDs, optoelectronic products, etc. Their main function is to mold plastic materials by heating and pressure, and to encapsulate electronic components in the plastic to provide protection and insulation.

[0003] Application No. CN202222944614.8 discloses a molding die. By setting a clearance mechanism, during the mold closing process, when the positioning element reaches the position of the second mold, it can retract towards the first mold, thereby reducing the pressure between the positioning element and the second mold and preventing puncture of the surface structure of the second mold (e.g., release film). Thus, after mold closing, the positioning element can be positioned above the second mold, avoiding contamination by overflowing molding compound, thereby ensuring the molding quality of the part to be molded.

[0004] However, compared with the plastic sealing mold in the patent, it is difficult to apply a release agent to the inner wall of the mold, especially the inner wall of the lower mold, before use. Therefore, during the subsequent demolding process, the workpiece may be difficult to separate from the mold quickly, and the demolding is difficult. To this end, we propose a panel-type plastic sealing mold that is easy to demold. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a panel-type plastic sealing mold that facilitates demolding. By setting up a demolding component, a linear motor drive, a support, and a brush plate move to the right along the linear motor guide rail, bringing them directly above the mold release agent tank. Then, an electric push rod drives the brush plate downwards, allowing it to enter the mold release agent tank through a groove and pick up the mold release agent. Next, the electric push rod drives the brush plate upwards, and the linear motor drive, a support, and the brush plate move to the left along the linear motor guide rail, bringing the brush plate above the lower mold. The electric push rod then drives the brush plate downwards, allowing the bottom of the brush plate to fit against the bottom of the lower mold. The process continues to move to the left, using the mold release agent on the brush plate to coat the lower mold, facilitating subsequent demolding and reducing demolding difficulty.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A panel-type plastic sealing mold that facilitates demolding includes a base, a lower mold provided at the upper end of the base, a first demolding component connected to the upper end of the base, a second demolding component connected to the outside of the lower mold, and a mold assembly connected to the upper end of the base.

[0008] The demolding assembly includes a linear motor guide rail, which is fixedly connected to the upper end of the base. A linear motor actuator is slidably connected to the upper end of the linear motor guide rail. A guide rod is fixedly connected to the upper end of the base. A guide block is slidably connected to the outside of the guide rod. A bracket is fixedly connected to the upper end of the guide block and the linear motor actuator. An electric push rod is fixedly connected to the lower end of the bracket. A brush plate is fixedly connected to the output end of the electric push rod. A mold release agent tank is fixedly connected to the upper end of the base. A groove is formed at the upper end of the mold release agent tank, which is adapted to the brush plate. The brush plate is adapted to the lower mold.

[0009] By setting up demolding component one, the linear motor mover base drives the bracket, brush plate, etc. to move to the right along the linear motor guide rail, so that it is directly above the mold release agent tank. Then, the electric push rod one drives the brush plate to move downward, so that the brush plate enters the mold release agent tank from the groove and dips into the mold release agent. Then, the electric push rod one drives the brush plate to move upward, and the linear motor mover base drives the bracket, brush plate, etc. to move to the left along the linear motor guide rail, so that the brush plate is above the lower mold. The electric push rod one drives the brush plate to move downward, so that the bottom of the brush plate fits against the bottom of the lower mold. Then, it continues to move to the left, using the mold release agent on the brush plate to coat the lower mold, so as to facilitate subsequent demolding and reduce the difficulty of demolding.

[0010] Furthermore, the demolding assembly two includes an electric push rod two, which is fixedly connected inside the base, and a telescopic rod is fixedly connected inside the base.

[0011] By setting up demolding component two, the lower mold can be flipped and inverted after the plastic material is formed, thereby using gravity to accelerate demolding.

[0012] Furthermore, the output end of the electric push rod 2 and the telescopic end of the telescopic rod are both fixedly connected to connecting blocks, which are symmetrically distributed from left to right.

[0013] Furthermore, a drive motor is fixedly connected inside the connecting block on the left, and an output shaft is fixedly connected to the output end of the drive motor.

[0014] Furthermore, the output shaft is rotatably connected to the connecting block, the output shaft is fixedly connected to the lower mold, and the lower mold is rotatably connected to the connecting block.

[0015] Furthermore, the mold assembly includes a support rod, which is fixedly connected to the upper end of the base, and a top plate is fixedly connected to the upper end of the support rod.

[0016] Furthermore, a hydraulic cylinder is fixedly connected to the upper end of the top plate, and an output rod is fixedly connected to the lower end of the output end of the hydraulic cylinder, with the output rod slidably connected to the top plate.

[0017] Furthermore, the lower end of the output rod is fixedly connected to an upper mold, which is adapted to the lower mold.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. By setting up demolding component one, the linear motor moving base drives the bracket, brush plate, etc. to move to the right along the linear motor guide rail, and come to the top of the mold release agent tank. Then, the electric push rod one drives the brush plate to move downward, allowing the brush plate to enter the mold release agent tank from the groove and dip into the mold release agent. Then, the electric push rod one drives the brush plate to move upward, and the linear motor moving base drives the bracket, brush plate, etc. to move to the left along the linear motor guide rail, allowing the brush plate to come to the top of the lower mold. The electric push rod one drives the brush plate to move downward, allowing the bottom of the brush plate to fit against the bottom of the lower mold. Then, it continues to move to the left, using the mold release agent on the brush plate to apply to the lower mold, so as to facilitate subsequent demolding and reduce the difficulty of demolding.

[0020] 2. By setting up demolding component two, the lower mold can be flipped and inverted after the plastic material is formed, so that gravity can be used to accelerate demolding. Attached Figure Description

A linear motor mover seat 302 is slidably connected to the upper end of the linear motor guide rail 301. A guide rod 303 is fixedly connected to the upper end of the base 1. A guide block 304 is slidably connected to the outside of the guide rod 303. A bracket 305 is fixedly connected to the upper end of the guide block 304 and the linear motor mover seat 302. An electric push rod 306 is fixedly connected to the lower end of the bracket 305. A brush plate 307 is fixedly connected to the output end of the electric push rod 306.

The groove 309 is adapted to the brush plate 307, and the brush plate 307 is adapted to the lower mold 2.

[0031] By setting the demolding component 3, the linear motor mover 302 drives the bracket 305, brush plate 307, etc. to move to the right along the linear motor guide rail 301, and they come to the top of the mold release agent tank 308. Then, the electric push rod 306 drives the brush plate 307 to move downward, so that the brush plate 307 enters the mold release agent tank 308 through the groove 309 to pick up the mold release agent. Then, the electric push rod 306 drives the brush plate 307 to move upward, and the linear motor mover 302 drives the bracket 305, brush plate 307, etc. to move to the left along the linear motor guide rail 301, so that the brush plate 307 comes to the top of the lower mold 2.

Then, it continues to move to the left, using the mold release agent on the brush plate 307 to apply to the lower mold 2, so as to facilitate subsequent demolding and reduce the demolding difficulty.

[0033] By setting the demolding component 2 4, the lower mold 2 can be flipped and inverted after the plastic material is molded, thereby using gravity to accelerate demolding.

[0034] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the output end of the electric push rod 401 and the telescopic end of the telescopic rod 402 are both fixedly connected to connecting blocks 403, which are symmetrically distributed on the left and right.

[0037] After the plastic is molded, the electric push rod 401 drives the connecting block 403 and the lower mold 2 to move upward, and at the same time drives the telescopic rod 402 to extend and retract, leaving appropriate space for the lower mold 2 to flip. Then the drive motor 404 drives the output shaft 405 and the lower mold 2 to rotate, so that the lower mold 2 can be flipped 180 degrees and inverted, allowing the workpiece to be demolded faster by gravity.

[0038] Reference Figure 1 and Figure 5 As shown, the mold assembly 5 includes a support rod 501, which is fixedly connected to the upper end of the base 1, and a top plate 502 is fixedly connected to the upper end of the support rod 501.

The output rod 504 is slidably connected to the top plate 502.

[0040] After the plastic material is injected into the lower mold 2, the hydraulic cylinder 503 drives the output rod 504 and the upper mold 505 to move downward, applying pressure to the lower mold 2 and the plastic material to form it.

[0041] Specific implementation process: Before injecting plastic material, the linear motor actuator 302 drives the bracket 305, brush plate 307, etc. to move to the right along the linear motor guide rail 301, and arrives directly above the mold release agent tank 308. Then, the electric push rod 306 drives the brush plate 307 to move downward, allowing the brush plate 307 to enter the mold release agent tank 308 through the groove 309 to pick up the mold release agent. Then, the electric push rod 306 drives the brush plate 307 to move upward, and the linear motor actuator 302 drives the bracket 305, brush plate 307, etc. to move to the left along the linear motor guide rail 301, allowing the brush plate 307 to come above the lower mold 2. The electric push rod 306 drives the brush plate 307 to move downward, allowing the bottom of the brush plate 307 to fit against the bottom of the lower mold 2. Then, it continues to move to the left, using the mold release agent on the brush plate 307 to coat the lower mold 2, so as to facilitate subsequent demolding and reduce the difficulty of demolding.

[0042] After the plastic material is injected into the lower mold 2, the hydraulic cylinder 503 drives the output rod 504 and the upper mold 505 to move downward, applying pressure to the lower mold 2 and the plastic material to shape it.

[0043] After the plastic is molded, the upper mold 505 separates from the lower mold 2. The electric push rod 401 drives the connecting block 403 and the lower mold 2 to move upward, while simultaneously driving the telescopic rod 402 to extend and retract, leaving appropriate space for the lower mold 2 to flip. Then, the drive motor 404 drives the output shaft 405 and the lower mold 2 to rotate, so that the lower mold 2 can be flipped 180 degrees and inverted, allowing the workpiece to be demolded faster by gravity.
