Demoulding device for water filling nozzle of automobile water tank cover

Abstract

The invention discloses a demoulding device for a water filling nozzle of an automobile water tank cover. The demolding device comprises a sliding table base (4), first forming sliding blocks (12), a second forming sliding block (13), a sliding block insert pin (11) and a linkage drive mechanism. The linkage drive mechanism is connected to the sliding table base (4). The number of the first forming sliding blocks (12) is two, and the two first forming sliding blocks (12) form the tank cover water filling nozzle after being coupled and are both connected with the linkage drive mechanism. After the above structure is adopted, the linkage drive mechanism can be in linkage to enable demoulding of the sliding block insert pin and demoulding of the first forming sliding blocks to be conducted synchronously, then demoulding together with the second forming sliding block is achieved, and the purpose of complete demoulding is achieved. Accordingly, the action is clear, the steps are reasonable, and products are not damaged.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a demoulding device for an air intake grid assembly. Background technique [0002] The car radiator, also known as the radiator, is the main component of the car cooling system. Its function is to dissipate heat. The cooling water absorbs heat in the water jacket, flows to the radiator, dissipates the heat, and then returns to the water jacket to circulate. Wen, it is an integral part of the car engine. The tank cover of the automobile water tank is a plastic part formed by injection molding, including the water injection port on the tank cover is also integrally formed by injection molding. In the prior art, if attached figure 1 As shown in , there is often a side pipe 3 at the water injection port 2 of the water tank cover 1 of the automobile. Its function is to prevent the steam from opening the sealing valve of the water tank cover when the water tank is high temperature, an...

AI Technical Summary

Problems solved by technology

[0003] However, since the side pipe is arranged in the radial direction of the water tank cover water injection port, and the side pipe is in an inclined downward state, therefore, in the injection mold of the automobile water tank cover, the demoulding structure here Very complex, difficult to demould, and even damage the product quality of injection molded parts
