Lower die with transfer part

Technical Field

The utility model discloses be applied to the continuous atmosphere sintering hot briquetting device of airtight type to the hot briquetting product, especially a bed die that the utensil moved the portion of carrying.

Background

At present, hot press forming is a processing method of high polymer materials, which is mainly to place a material with a certain thickness in a mold, heat the mold or the environment to soften the material and cover the surface of the mold, then press the material by a machine, and solidify the material through a cooling stage to obtain a hot press formed product.

The material of the hot press molding is, for example, glass, which has a high light transmission property, so that display devices (such as mobile phones, watches, and other electronic products) are often used as the housing of the window portion. The surface of the handheld electronic product is usually provided with a glass shell to protect the display module inside the product. At present, most of glass shells are flat-plate shapes, so seams are formed on the upper surfaces of electronic products. Moreover, since the periphery of the electronic product must retain a mechanism portion with a certain width for holding the flat glass, the top surface of the electronic product cannot be fully utilized. Therefore, the three-dimensional or curved glass is gradually applied to the glass housing of the electronic product.

The flat plate type glass shell is easy to manufacture, and the glass shell with a three-dimensional shape is difficult to manufacture. At present, there are two general methods for manufacturing a glass housing having a three-dimensional shape: the first one is: a plurality of flat glass units are manufactured, and then a glass shell with a three-dimensional shape is formed by means of pasting edges. The second method is as follows: manufacturing cuboid glass with a certain thickness, and then grinding the cuboid glass for multiple times to form a three-dimensional shape with multiple sides. However, both of the above methods are time and labor consuming and the production speed is very slow. Generally, since the glass material is flat, if a glass having a shape is to be produced, it is preferable to dispose the flat glass material between an upper mold member and a lower mold member, and then heat the upper mold member, the lower mold member and the glass material to soften the glass material. When the glass material is softened, the upper mold part and the lower mold part can be closed, so that the upper mold part and the lower mold part jointly mold the appearance of the glass material along a mold closing direction, and the corresponding molded glass is produced. Taiwan patent publication No. M452174, "molding apparatus for manufacturing molded glass" (published as 2013, 05, and 01), includes a female mold, a first male mold, a second male mold, a supporting pin, and a pressing pin. The first male mold piece is arranged on the female mold piece in an openable and closable manner, and the second male mold piece is arranged between the female mold piece and the first male mold piece. The supporting ejector rod penetrates through the female mould piece and is used for pushing the second male mould piece so as to support the second male mould piece and the first male mould piece to clamp molded glass together. The pressure lever is arranged on one side of the first male die piece and used for pressing down the first male die piece so as to enable the first male die piece and the second male die piece to move to a die closing position relative to the female die piece, and therefore the molded glass is molded. However, the demand of continuously and rapidly manufacturing high quality molded three-dimensional glass in the industry can not be met.

Referring to fig. 1, fig. 1 is a side view of a conventional vertical heating type molding apparatus, which mainly includes an upper heating plate a, a bottom heating plate B, and a displacement mechanism C, wherein a mold D is disposed on the bottom heating plate B, and the displacement mechanism C is used to shift the displacement mold D.

Because the exchange system is arranged outside the furnace body and is displaced by the carrier plate in the furnace, the defect that the displacement mechanism is easy to deform or damage due to high temperature in the furnace in the prior art is avoided. However, since the thickness of the carrier plate is spaced from the thickness of the lower heating plate between the carrier plate and the lower heating plate, the indirect contact heating has room for improving the heating and cooling speed due to the thickness of the carrier plate between the mold and the lower heating plate, and it is necessary to provide a better design to improve the continuous hot press molding apparatus.
