Embodiment 1

[0021] as attached figure 1 And attached figure 2 As shown, a cooling mold for fuse box cover includes a frame, an upper mold 1 and a lower mold 10, the upper mold 1 is a concave mold and is slidably connected with the frame, and the upper mold 1 can slide vertically on the frame. Lower mold 10 is punch and is fixed with frame. When the upper mold 1 and the lower mold 10 are engaged, a molding cavity is formed between the upper mold 1 and the lower mold 10 . The upper mold 1 is provided with an injection port 3 connected to the molding cavity, through which the thermoplastic is injected into the molding cavity. The upper mold 1 is provided with a cooling channel 2 to prevent the plastic melt from entering the cooling channel 2. The cooling channel 2 and the thickness of the side wall of the molding cavity is 3cm. Both ends of the cooling channel 2 are provided with wedges 4 slidably connected to the upper mold 1 , and the wedges 4 can slide horizontally relative to the upp...

Abstract

The invention relates to the technical field of die processing and discloses a cooling die for a fuse box cover body. The cooling die comprises a rack, an upper die and a lower die; the upper die is aconcave die; the lower die is a convex die; a formation cavity is formed between the upper die and the lower die when the upper die is locked with the lower die; the upper die is provided with an injection molding hole which is communicated with the formation cavity and is internally provided with a cooling channel; the lower die is internally provided with a water storage channel and an air cavity; the water storage channel is internally provided with a pushing plate; venturi pipes are arranged at the two ends of the water storage channel respectively and are communicated with the water storage channel; an air pipe which is communicated with each venturi pipe is arranged at a throat pipe of each venturi pipe; the air cavity is internally provided with a sliding plate which is in verticalsliding connection with the lower die; the air cavity below the sliding plate is communicated with the water storage channel below the pushing plate, and an electromagnetic valve is arranged at the communication part; the sliding plate is provided with a connection rod; one end of the connection rod is arranged in the cooling channel; the air cavity below the sliding plate is provided with an airinlet one-way valve; and a bulge of the upper die is provided with a heat conduction sheet which extends into the air cavity. The cooling die is simple in structure and can rapidly perform cooling ona product in the die.

Description

technical field [0001] The invention relates to the technical field of mold processing, in particular to a cooling mold for a fuse box cover. Background technique [0002] The fuse box refers to the box where the fuse is installed, also known as the fuse holder. In order to facilitate the installation of the fuse, some fuse boxes also have the performance characteristics of waterproof and high temperature resistance. [0003] In order to achieve the waterproof function of the fuse box, the fuse box cover plate is required to seal the fuse box, and the cover plate used to seal the fuse box needs to be made of a mold. Molds are used in industrial production to obtain various molds and tools required by accommodation, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods. It is mainly a tool that makes the blank Chen Wei have a specific shape and size under the action of external force. The traditional mold is mainly composed of an uppe...
