[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: to design a keyboard keycap injection molding mold that can improve the yield rate, including a carrier, a lower mold body is fixedly connected to the middle of the carrier, a plurality of cavities are opened inside the lower mold body, model blocks of matching sizes are installed inside the cavities, the bottom of the model block is connected to the connecting plate through a top column, the bottom end of the push plate is fixedly connected to the output end of the first electric push rod, the edge of the carrier is fixedly connected to a mounting plate, the mounting plate is connected to a push plate through a second electric push rod, and both sides of the push plate are fixedly connected to limiting plates.

[0006] Preferably, support frames are fixedly connected to both sides of the carrier, and the support frames are connected to two fixed plates through two hydraulic rods. An upper mold body is fixedly installed between the two fixed plates, and an injection port is fixedly connected to the middle of the top of the upper mold body.

[0007] Preferably, the mounting ends of the two hydraulic rods are fixedly connected to both sides of the top end of the support frame, and the output ends of the hydraulic rods are fixedly connected to the top end of the fixing plate.

[0012] The utility model combines the model block, the push column, the connecting plate, the first electric push rod, the ramp plate, the collecting box, the second electric push rod, the pushing plate and the limit plate. After the key cap is formed, the hydraulic rod first drives the upper mold body to separate from the lower mold body, and then the first electric push rod drives the connecting plate to move upward. At this time, the connecting plate drives the model block in the cavity to move upward through a plurality of push columns, so that the manufactured key cap is pushed out of the cavity, so that the key cap in the molding mold can be taken out at one time, which speeds up the speed of taking the key cap out of the molding mold.

[0013] When the keycap is moved out of the cavity, the second electric push rod drives the push plate to move. At this time, the push plate will push the keycap on the lower template into the ramp plate, and then the ramp plate will guide the keycap into the collection box, thereby realizing the automatic collection of the manufactured keycaps and improving the efficiency of collecting the keycaps. In this process, the limit plate will block the two sides of the lower template to prevent the keycap from falling off the lower template during the pushing process.
