Description

A New Forming Mold Outside the Furnace of Tempered Glass

technical field

The utility model relates to an automobile glass mould, in particular to a novel tempered glass out-of-furnace molding mould.

Background technique

At present, with the development of the automobile industry, the performance requirements and demand for automobile glass are getting higher and higher. Today, when energy saving, consumption reduction, high efficiency and environmental protection are advocated, the existing automobile tempered gears, side windows, triangles and skylights, etc.) production equipment and molds will be somewhat unable to cope with the increasingly high product requirements. The original GT tempering furnace has certain limitations in production capacity and production costs. Compared with For the new type of BT furnace and external forming furnace, when producing tempered glass with small area such as side window, triangle and skylight glass, there are defects such as inaccurate positioning of the glass in the furnace, high energy consumption, low production capacity, and high cost. The corresponding mold also has the same problem. The mold has a relatively high development cycle and cost, and also has the defect of a long mold change time, which obviously restricts production efficiency.

Contents of the invention

The purpose of this utility model is to provide a new type of toughened glass furnace external forming mold which can reduce the heat loss of the mold and increase the output rate per unit time in order to overcome the above-mentioned defects in the prior art.

The purpose of this utility model can be achieved through the following technical solutions:

A new tempered glass furnace forming mold, the mold is a glass furnace forming mold, the mold includes a convex mold and a concave mold, the bottom surface of the convex mold is provided with a convex mold surface, and the top surface of the concave mold is A concave mold surface is provided on the top, and the convex mold surface and the concave mold surface are set opposite to each other and contact the two sides of the glass respectively.

The punch is also provided with a punch positioning hole for fixing, a punch cavity for placing a heating rod, and a punch center positioning hole for positioning.

The convex mold surface is provided with evenly distributed convex mold vacuum holes.

The said die is also provided with a die supporting frame, a die center positioning hole and a die fine-tuning bolt, and the die supports are set up on the four corners of the die, and the center positioning hole of the die is connected with the punch Corresponding setting of center positioning hole.

The concave mold surface is an annular structure, and the concave mold fine-tuning bolts are evenly distributed around the concave mold surface.

The die supporting frame is provided with a die positioning groove for fixing.

Compared with the prior art, the utility model changes the original molding process of toughened glass in the furnace, and changes it to molding outside the furnace, which reduces the requirement on the mold temperature during glass molding; changes the structure of the mold, and uses aluminum Replacing the original stainless steel material reduces the weight of the mold and directly reduces the material cost. At the same time, because the thermal conductivity of aluminum is better than that of stainless steel, the heat loss of the mold is reduced, so the energy consumption of glass production is reduced; and the new mold structure is in the mold movement. and mold change time have been effectively improved, so that the production capacity of the equipment has been greatly improved; at the same time, because of the rapid mold change outside the furnace, the mold change time is greatly shortened, reducing downtime, and effectively reducing the unit energy consumption.

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

Example

As shown in Fig. 1-Fig. 5, a kind of molding mold outside the furnace of a kind of tempered glass, this mold is the molding mold outside the glass furnace, comprises convex mold and concave mold, and described convex mold bottom surface is provided with convex model surface 4, so The top surface of the concave mold is provided with a concave mold surface 7, and the convex mold surface 4 and the concave mold surface 7 are arranged opposite to each other and contact the two sides of the glass respectively.

The punch is also provided with a punch positioning hole 1 for fixing, a punch cavity 2 for placing a heating rod, and a punch center positioning hole 5 for positioning. Evenly distributed punch vacuum holes 3, the punch is fixed on the equipment through the punch positioning hole 1.

Also be provided with die supporting frame 6, die center positioning hole 8 and die fine-tuning bolt 9 on described die, described die supporting frame 6 is arranged on the four corners of die, is provided with for fixing on it. The positioning groove of the die, the center positioning hole 8 of the die is set corresponding to the center positioning hole 5 of the punch. The concave mold surface 7 is an annular structure, and the concave mold fine-tuning screws 9 are evenly distributed around the concave mold surface 7 .

After the above-mentioned mold is manufactured, install the punch on the equipment through the positioning hole 1 of the punch. After the installation is completed, the heating rod on the equipment will extend into the cavity 2 of the punch; The positioning groove of the die is installed on the equipment, and then the position of the die is adjusted through the center positioning hole 8 of the die and the center positioning hole 5 of the punch. When the center of the die coincides with the center of the punch completely, the position of the die is fixed. Then adjust the die gap by adjusting the die fine-tuning bolt 9 on the die, so that the gap around the die is even.

As shown in Figure 6, when producing glass, the punch is heated to the glass forming temperature through the heating rod embedded in the cavity 2 of the punch, and when the temperature sensed by the sensor on the device reaches the forming temperature, the glass passes through the ceramic roller and When the roller is transferred to the top of the die, the die will rise, use the concave model surface 7 to lift the glass to a certain height, and then the punch will drop to a suitable height at this time, and use the convex model surface 4 and the concave model surface 7 to press together At the same time, the glass is pumped through the vacuum hole 3 of the punch, so that the glass is tightly attached to the surface 4 of the convex mold to make it fully formed. For air blowing, the pressed glass is blown onto the forming ring, and the forming ring is connected to the glass and retreated to the toughened air grid, and the glass is quenched and tempered to complete the production of the whole piece of glass.
