Detailed Description

One embodiment of the present utility model will be described in detail below with reference to the attached drawings, but it should be understood that the scope of the present utility model is not limited by the embodiment.

As shown in fig. 1-3, the right-angle composite material box body molding slide block mold provided by the embodiment of the utility model comprises a mold body, wherein the mold body comprises a female mold 1, a male mold 2, a mold core 3 and a guide assembly 4, one end of the mold core 3 is connected with a limiting block 5, the limiting block 5 is limited by a limiting groove 6 on the female mold 1 and the male mold 2, one side of the mold core 3 except for the limiting block 5 is respectively provided with a slide block 7, the slide block 7 is slidably connected onto the male mold 2, the outer side of the slide block 7 is provided with a first inclined surface 8, a second inclined surface 9 matched with the first inclined surface 8 is arranged at a corresponding position of the female mold 1, under the action of pressure, the second inclined surface 9 is in matched contact with the first inclined surface 8, the slide block 7 is driven to approach the mold core 3, a negative pressure channel 10 is arranged on the female mold 1, a sealing ring 12 is arranged between the negative pressure channel 10 and the female mold 1 and the male mold 2, the vacuum pumping treatment is performed in the compression molding process, the inner porosity of a product is reduced, and the product quality is improved.

Preferably, the corresponding position of the male die 2 is provided with a sliding limit groove 13, and a sliding protrusion matched with the sliding limit groove 13 is arranged below the sliding block 7.

Preferably, the guide assembly 4 comprises a guide sleeve 41 provided on the female die 1 and a guide post 42 provided on the male die 2.

The working principle of the utility model is as follows:

sequentially paving the composite prepreg on the mold cores 3 according to a design drawing, then placing the paved mold cores 3 in limit grooves 6 of the male mold 2, sequentially mounting the sliding blocks 7 on the male mold 2 respectively, and sequentially pushing the sliding blocks 7 towards the mold cores 3 to enable the sliding blocks 7 to be closely attached to the prepreg; and then the female die 1 and the male die 2 are matched, and then the die is placed on a heating press for stage pressurization, and vacuum pumping is carried out in a time-sharing manner in the pressurization process. In the pressurizing process, the sliding block 7 slides to the innermost side under the cooperation driving of the first inclined surface 8 and the second inclined surface 9, so that the vertical surface performance of the box body can be ensured, the cracking of materials is reduced, the upper die and the lower die are combined, and the final product is molded.
