Description

A mold pressing device

technical field

The utility model relates to a die frame pressing device.

Background technique

The trunk cover for car trunk decoration is generally formed by cold pressing of PP board hot material. Due to the complex shape of the suitcase and the large stretching depth of the material, once the local uneven stretching is formed, the material will be torn. And because the shape of the luggage cover is too complicated, it is easy to produce local uneven stretching during the production process. In the previous production, in order to avoid tearing, the only way to avoid breaking was to increase the thickness of the PP sheet raw material, which greatly increased the manufacturing cost of the product and reduced the competitiveness of the product.

As shown in Figure 1, the prior art provides a mold pressing frame device, including: upper mold cylinder 100, upper mold 200, upper mold pressing frame 300, lower mold pressing frame 400, lower mold 500 and lower mold cylinder 600, upper mold The cylinder 100 is fixed on the upper mold 200, the lower mold cylinder 600 is fixed on the lower mold, the piston rod of the upper mold cylinder 100 is fixedly connected with the upper mold pressing frame 300, and the upper mold cylinder 100 is used for the piston rod of the lower mold cylinder 600 and the lower mold pressing frame 400 is fixedly connected, the profile of the product is arranged on the upper die 200, and the profile of the product is also correspondingly provided on the lower die 500. During the mold clamping process of the mold press frame device, the upper mold cylinder 100 pushes the upper mold press frame 300 to move downward, the lower mold cylinder 600 pushes the lower mold press frame 400 to move upward, and the upper mold 200 gradually moves downward under the drive of the press, The upper mold press frame 300 and the lower mold press frame 400 gradually contact and tighten the material plate. Since the pressure of the press is far greater than the supporting force provided by the lower mold cylinder 600, when the upper mold continues to move down, the upper mold 100 and the upper mold press frame 300 will Gradually press the lower molding frame 400 to the limit position (that is, the piston rod of the lower molding cylinder 600 is gradually retracted into the lower molding cylinder 600), during this process, the material plate also moves downward with the upper molding frame 300 and the lower molding frame 400 , which will cause the material plate to come into contact with the lower die prematurely. Due to the complex profile and large drop of luggage products, some sharp protrusions (ie hanging points) will hang the material tightly. When the upper mold product is formed, the entire material plate cannot be stretched freely after the material is hung. It can only be stretched between the material hanging points, so the thickness of the entire product will be uneven and cracks will occur.

As shown in Figure 2-5, the dotted line in the figure represents the profile of the product. According to an embodiment of the utility model, the working process of the mold pressing device of the utility model is as follows:

During the initial state, the air cylinder of the lower mold is controlled to inflate, and the piston rod of the lower mold cylinder pushes the lower mold pressing frame 6 to move upward until the piston rod of the lower mold cylinder fully stretches out. Due to the self-gravity of the upper molding frame 2, and the guide rod 8 and the guide seat 7 can slide relatively freely, the upper molding frame 2 slides downward until the guide block 72 of the guide seat 7 touches the anti-off structure 81 on the guide rod 8 (raised).

At this time, the material plate, such as a PP plate, can be heated and placed on the lower molding frame 6 . The upper mold 1 moves down slowly under the drive of the press, and when the upper molding frame 2 and the lower molding frame 6 contact, the upper molding frame 2 and the lower molding frame 6 cooperate to clamp the material plate.

Thereafter, the upper die 1 continues to move down, and the guide seat 7 moves downward along the guide bar 8, that is, the upper die pressing frame 2 moves upward relative to the upper die 1 (at this time, the upper die pressing frame 2 is motionless, and the upper die pressing frame 2 and the lower die pressing frame 2 move upward. Frame 6 is always in contact), the material plate is gradually stretched to fit the profile of the upper die 1, when the guide seat 7 slides to the bottom end of the guide rod 8 (that is, the threaded end), the material plate is basically in line with the profile of the upper die 1 fit.

Afterwards, the upper mold 1 moves down further. Since the pressure of the press is much greater than the thrust provided by the cylinder of the lower mold, the upper mold pressing frame 2 and the lower mold pressing frame 6 move downward together at this time, and the material plate gradually contacts the profile surface of the lower mold 5 , and finally, the upper mold 1 and the lower mold 5 are bonded together, and the material plate is pressed into shape.

During the working process of the die frame pressing device of the present utility model, since the material plate is first stretched by the upper die 1, when it comes into contact with the lower die 5 and in the subsequent bonding process, the influence of the material hanging point on the stretching of the material plate has already It is greatly reduced, so the thickness of the product is more uniform, and there will be no phenomenon of material tearing, which effectively improves the quality of the product; at the same time, it is not necessary to thicken the material to prevent material tearing, so the cost is also effectively reduced.

The mold pressing frame device of the utility model is provided with an upper mold guiding mechanism 3, so that the upper mold pressing frame 2 and the upper mold pressing frame 1 can slide relatively. The mold 1 can slide upwards, that is, the material is first uniformly stretched by the upper mold 1 and then formed under the action of the upper mold 1 and the lower mold 5, so the mold pressing device of the utility model can make the thickness of the product more uniform.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model.
