Background Art

[0002] Hot pressing forming is a commonly used composite material forming process. Its basic principle is to cure prefabricated reinforcing materials and matrix resins under high temperature and high pressure to form the final composite material products.

[0003] Consumer products are gradually developing towards a more complex design direction. End users have higher standards for the dimensional accuracy and appearance texture of such products. The hot pressing forming process can meet the design of such products. However, in the face of different production requirements, different mold structures need to be designed to produce such products to meet the production goals of different products.

[0004] In view of this, it is necessary to provide a rotating slider mechanism for hot pressing forming to solve the above problems.

Summary of the Invention

[0005] The technical problem to be solved by the present invention is that in the face of the production requirements of different products, different mold structures need to be designed to produce such products to meet the production goals of different products. Therefore, creating a new type of mechanism is the direction of our research and development. Thus, the present invention provides a rotating slider mechanism for hot pressing forming to solve the above problems.

[0006] The solution of the present invention to solve its technical problem is: a rotating slider mechanism for hot pressing forming, comprising:

[0007] A lower mold base, the lower mold base is fixed on the machine table through a fixing member. One side of the lower mold base is fixed with a guide sleeve through a fixing member. The guide sleeve can cooperate with the guide post of the upper mold base for positioning the upper mold base. The lower mold base is fixed with a balance block through a fixing member. The balance block is used for balancing and supporting the upper mold core. The lower mold base is fixed with a lower mold core through a fixing member. One end of the lower mold core is shaped like the product and can cooperate with the upper mold core to form the product;

[0008] An upper mold base, one end of the upper mold base can be fixedly connected to a power device for moving the upper mold base under the control and drive of the power device. The other end of the upper mold base is fixed with a guide post through a fixing member. The guide post can be inserted into the guide sleeve of the lower mold base for positioning the upper mold base. The upper mold base is movably connected with an upper mold core through a movable member. The upper mold core can move on the movable member through an elastic member. The upper mold core is shaped like the other end of the product and is used for cooperating with the lower mold core to form the product. A rotating slider and a pressing plate are arranged between the upper mold core and the upper mold base; wherein,

[0009] Rotate the slider. The rotating slider is divided into a first rotating slider and a second rotating slider. One end of the first rotating slider and the second rotating slider is movably connected by a rotating member, and the other end is provided with a sliding shaft.

The other end of the upper die base 200 is fixed with a guide post 210 through a fixing member 110. In this embodiment, there are four groups of the guide posts 210, which can be respectively inserted into the four groups of guide sleeves 120 of the lower die base 100 for positioning the upper die base 200. The upper die base 200 is movably connected to an upper die core 230 through a movable member 220. The upper die core 230 can move on the movable member 220 through an elastic member 240. In this embodiment, there are four groups of the movable members 220 and six groups of the elastic members 240, which can enable the upper die core 230 to stably move on the movable member 220 through the elastic member 240. The upper die core 230 is shaped to fit the other end of the product 300 and is used to cooperate with the lower die core 140 to form the product 300. There is a rotary slider 250 and a pressing plate 260 between the upper die core 230 and the upper die base 200; wherein,

[0034] A rotary slider 250, the rotary slider 250 is divided into a first rotary slider 251 and a second rotary slider 252.
