detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

Referring to Fig. 1-Fig. 7, a hot pressing mold for composite material molding with flanging structure, including an upper mold 1, a middle mold 2, a lower mold 3, and a mold core 4; the lower mold 3 is fixed on the press On the platform, the upper die 1 fixes the lower part of the press platen, the middle die 2 includes a slide block 2a and a slide block track seat matched therewith, and the slide block track seat is fixed on the upper part of the lower die 3; the mold core 4 is fixed on the slide block. On the block track seat, the mold core 4 is a rectangular body structure, and the upper part and the side of the mold core are provided with composite materials that need to be hot-pressed; on the four sides of the hot-pressing mold, at least two sides have inclined guide posts 5, and each side The number of slanted guide pillars 5 is one or multiple in parallel; when the mold closing is completed, the slanted guide pillars 5 pass through the slider 2a, the slider track seat, and the lower mold 3 obliquely from top to bottom to the outside. In the corresponding hole of the upper mold 1 and the upper surface of the mold core 4, the slider 2a slides inward under the action of the inclined guide column 5 and is pressed against the side of the mold core 4; when the mold opening is completed, the The upper mold 1 is lifted upwards, and the inclined guide column 5 is separated from the hole of the lower mold 3, and drives the slider 2a to slide outward along the slider track seat, and the composite material with flanging structure is pressed.

Referring to FIG. 1 , multiple parallel guide pillars 5 are arranged side by side in the peripheral direction of the hot pressing mold, and the number of inclined guide pillars 5 on each side is a plurality of parallel guide pillars.

Referring to FIG. 3 , the lower part of the lower mold 3 is provided with a heightening block, and the heightening block is arranged on the press platform, and the inclined guide column 5 is inserted downward into the heightening block.

Referring to Fig. 3, a slider stopper 2b is provided on the outside of the slider track seat, and the slider stopper 2b is L-shaped to limit the slider 2a.

The working process is to install and fix the mold on the press, in which the lower mold 3 and the heightening block are fixed on the press platform, the upper mold 1 is fixed with the platen of the press, and then the upper mold is raised and the guide column is inclined at the same time 5 With the slider 2a open, the operator can directly lay up and place the material in the mold. After the operator finishes the work, the upper mold 4 is slowly pressed down, and at the same time the guide post drives the slider 2a inward. , the pressure of the press is transmitted to the slider 2a through the upper mold 1, and finally all the force is applied to the material, and the mold is heated for vulcanization. After a certain vulcanization time and natural cooling, the mold is opened to obtain the product. See Figure 3-7 for details.

The utility model has composite materials with flanging structure hot press forming, the mold can be completed in one action, and the process is simple; the mold only needs the power of one-way movement; the labor intensity of the operator is reduced; the verticality and flatness of the hot press forming are effective All of them have been improved; the oblique guide pillars pass through the corresponding holes of the slider, slider track seat and lower die obliquely from top to bottom to the outside, with ingenious design and high reliability; the design of the slider stopper is ingenious, High reliability.

Further set forth innovation and the characteristic of the present utility model below:

Through the innovative design of the mold, the product can be evenly and fully stressed. Generally speaking, the traditional mold can only bear the force along the up and down direction of the press, but the force on the left and right sides cannot be exerted or the force is too small to ensure the product. Due to the requirements of the pressing process, sometimes the product cannot even be formed. This mold innovatively designed the slider, which directly transmits the force of the press to the material through the inclined surface of the slider, thus ensuring the force requirements of the material in the surrounding direction, and due to the sliding The contact between the block and the upper die is surface-to-surface, which ensures the effectiveness of force transmission. Through the adjustment of the angle of the slope, different levels of force can be transmitted to meet the process requirements of various products.

Through the innovative design of this mold, the automatic mold opening and automatic mold closing functions of the middle mold and the slider can be realized. Generally speaking, it is very difficult to open the mold of the traditional hot-pressing mold, especially the mold opening of the middle mold. When the press surface rises and takes away the upper mold, there are generally two methods for the mold opening of the middle mold: first, rely on the cylinder of the press to lift the product Ejection, which requires a high cost of the press and due to the use of hydraulic systems, oil leakage and other conditions are inevitable. Some non-metallic materials are not allowed to be polluted by external organic matter in the pressing process, which will cause the material to fail to form. The second is to manually open the mold, and use tools such as sticks to manually open the mold. For some large molds, artificial power cannot open the mold at all. The inclined guide post is innovatively designed in this mold, and the inclined guide post is installed in the upper mold to separate the middle mold from the slide block through the movement of the inclined guide post in the guide hole to achieve the purpose of mold opening, and only by pressing The self-starting function of the upper mold and the middle mold can be realized by the action of the machine rising. Because the power of the press machine is relatively large, there will be no situation that the mold cannot be opened. The labor cost is greatly reduced, and the pressing process that originally required 2 to 3 staff members can now be easily completed by only one person.

This mold adopts a structured and modular design language. The mold core, slider, and inclined guide post are all detachable. As long as the mold cores of different shapes are replaced, various other styles of products can be pressed. Due to the modular design Language, mold parts repair and replacement and post-maintenance are very convenient, only need to remove the corresponding parts can greatly reduce the maintenance cost, labor cost and time cost.
