Detailed Description

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the embodiment.

As shown in fig. 1-4, the mold for producing a civil air-proof airtight door and the molded product thereof provided by the embodiment of the present invention include a lower mold 1 and a cavity 2 engaged with the lower mold 1, where the lower mold 1 includes a lower cover plate 11, a lower mold leg 12 and a lower movable mold 13, the upper surface of the lower mold 1 (i.e. the upper surface of the lower movable mold 13) is provided with a product reinforced molding structure, the reinforced molding structure includes a plurality of inserts 3 with smooth surfaces, a gap 4 exists between adjacent inserts 3, the surface of each insert 3 is independently subjected to a smoothing treatment and then fixed on the upper surface of the lower movable mold 13, the smoothing treatment can include polishing, chrome plating and other common forms, and can ensure that the surface of each insert is smooth and easy to remove, so that the height of the insert can be greatly increased, the depth of the product reinforced structure can be correspondingly greatly increased, and materials can be greatly saved, reduce the weight of the product and be beneficial to enterprises to save the cost.

Strengthen the forming structure and strengthen the forming structure for cellular, insert 3 is the hexagon structure, the cellular additional strengthening of product, and its structural style is more stable, and the resistance to deformation ability is stronger, and intensity is higher.

The insert 3 is 5-12 cm high, so that on the premise of ensuring the strength of a product, materials are saved, the weight of the product is reduced, and the insert 3 is fixed on the lower moving die 13 of the lower die 1 through a plurality of long screws 22.

A plurality of air exhaust holes 5 and a plurality of sealing strips 6 are uniformly formed in the periphery of the upper portion of the lower die 1, the sealing strips 6 are arranged in sealing strip grooves, the air exhaust holes 5 are communicated with a main air channel 7, the main air channel 7 is connected with a vacuum pump through a connecting air hole 8, vacuumizing is performed through the structure, the space between the lower die 1 and the cavity 2 is guaranteed to be in a vacuum state, sufficient flowing of feed liquid can be guaranteed, bubbles are prevented from being generated, the quality of products is guaranteed, and the strength of the products is guaranteed.
