Hot press forming device

The present invention relates to the technical field of the structure of a hot press forming apparatus, and more particularly to a hot press forming apparatus which can quickly and accurately position without injecting a position or a mark line during feeding, and can avoid stacking order errors.

A conventional hot press forming apparatus, as disclosed in Taiwan Patent No. M420424, in which an operator needs to stack a plurality of thermoplastic materials pre-cut into a specific shape on a stage in order to complete the action of feeding. Then, the plurality of stacked thermoplastic materials are transported to the lower side of the upper mold by the stage, and the upper mold is pressed down onto the stage by the booster cylinder while using the heater pair disposed on the top of the upper mold. The plurality of thermoplastic materials on the stage are heated to complete the hot press forming operation, whereby the plurality of thermoplastic materials can be pressed and hot-melt combined into a thermoplastic composite.

In the conventional hot press forming device, in order to avoid skewing when stacking the thermoplastic material, the operator can usually only make a positioning mark on each layer of the thermoplastic material beforehand, and then the operator can then use the thermoplastic material of each layer. The tokens are stacked in sequence. However, not only does it take a lot of time to affect the processing efficiency in the process of presetting the positioning mark, but in order to prevent the positioning mark from affecting the appearance and quality of the formed thermoplastic composite, the positioning mark is usually impossible. Bright It is obvious that it can be easily painted, so it is easy to cause the operator to be difficult to locate or make the positioning inaccurate when feeding, for example, the positioning mark is made smaller than the upper layer of the thermoplastic material, so that after hot press forming The positioning marks will be covered by the upper layer of thermoplastic material, but the upper layer of the thermoplastic material will also be difficult to locate and inaccurate due to the positioning of the positioning marks when it is stacked. In particular, when the thermoplastic material of the upper layer is larger than the thermoplastic material of the lower layer, it is impossible to pre-set the mark on the thermoplastic material of the lower layer, and this causes troubles in the feeding, and seriously affects the quality. In addition, in order to make the thermoplastic composite have different characteristics and various patterns, it is usually required to stack a plurality of layers of different materials and shapes of thermoplastic materials on the stage, and the thermoplastic materials of the layers are thermoplastic. The different characteristics and patterns of the composite materials are also different in stacking order. However, this is not obvious and the positioning marks that are easy to be coated are more likely to cause confusion in the stacking order when feeding, which leads to a large increase in the defect rate.

Conventional hot press forming apparatuses have many problems such as inconvenient positioning, time consuming, inaccurate, and confusing order when feeding.

The present invention provides a hot press forming apparatus comprising a machine table, a stage, a projector, a heater and an upper mold. Wherein, the machine comprises a feeding zone and a forming zone. The loading platform can be moved from the feeding zone to the forming zone, and the loading platform can be used by the operator to sequentially stack the plurality of bonding materials on the table surface thereof as needed. The projector is disposed above the feeding area, and sequentially projects corresponding positioning images onto the table of the loading table according to the stacking order of the plurality of bonding materials, so that the operator The corresponding bonding material stacks may be sequentially positioned on the mesa of the stage according to the positions of the positioning images. The heater is disposed on the machine and can heat the plurality of bonding materials on the surface of the stage. The upper mold is disposed above the molding area, and when the stage and the plurality of bonding materials on the table surface thereof are moved to the molding area, the upper mold and the stage can press the plurality of bonding materials relative to each other to make the plural combination The material is hot pressed and combined into a composite material.

The hot press forming device provided by the present invention projects the corresponding positioning image onto the table surface of the stage in sequence according to the stacking order of the plurality of bonding materials, so that the operator can perform the positioning according to the positioning The position of the image sequentially positions the corresponding bonding material stack on the table surface of the stage. Therefore, it is possible to quickly and accurately position the material without printing the position or the marking line, and also avoid the stacking order error, thereby greatly improving the processing efficiency, the processing quality and the defect rate.
