Pallets are a kind of plastic products that are widely used in people’s daily life and transportation products in factories. Pallets are mainly made of pallet injection molds. The pallets need to adapt to different handling conditions, and usually the structure will change slightly. , In particular, there are many changes in the reinforcing ribs of the pallet. At present, people will remake a pair of molds according to each change, which will greatly increase the processing cost, and the pallet injection molds are relatively large in size, leading to replacement. Molds are very difficult.
The invention provides the following technical solutions: a tray injection mold, including a movable mold and a fixed mold, the movable mold is provided with a thimble double plate, and the thimble double plate is provided with a plurality of thimble rods penetrating the movable mold, so the The movable mold and the fixed mold are respectively provided with a first switching module and a second switching module that can interfere with each other, the cross-sections of the first switching module and the second switching module are square, and the first switching module and the second switching module are square The four identical sides of the switching module are respectively provided with forming blocks, and the movable mold and the fixed mold are respectively provided with a first fixing slot and a second fixing slot for fixing the first switching module and the second switching module.
Preferably, a first sliding rod is slidably connected to the side of the first fixing groove, the center of the first switching module is rotatably connected to the first sliding rod, and the first sliding rod is connected to the thimble double plate.
Preferably, a second sliding rod is slidably connected to the side of the second fixing groove, the center of the second switching module is rotatably connected to the second sliding rod, and a locking member is provided on the second sliding rod.
Preferably, a collision plate is provided on the side of the thimble compound plate close to the movable mold, the first sliding rod is fixedly connected to the side of the collision plate, and the collision plate and the thimble compound plate are connected by an elastic member.
