Description

Heating plate for leveling die casting and shaping die thereof

Technical Field

The utility model belongs to the technical field of a plastic mould for die casting flattening and specifically relates to a board and plastic mould generate heat for die casting flattening.

Background

Nowadays, as die-casting structural parts such as mobile phone parts and the like are increasingly pursuing lightness and thinness, the flatness requirement of the die-casting parts by people is increasingly strict, and the standard of common customers is that the flatness of the outer plane is less than or equal to 0.2 mm. In the production process of die castings, the flatness of the die-cast products is deformed to cause unqualified product sizes, and a shaping die is needed to ensure that the flatness is within the specification of less than or equal to 0.2 mm.

The conventional shaping method of the shaping die is to insert several straight heating rods 200 (as shown in fig. 1) into a heating plate 100 of the hot shaping die, and to realize the hot shaping of the die casting in the shaping die by the heating of the heating rods 200, but the method has the following defects in the specific use process: the shaping die is heated unevenly, so that the temperature difference between the actually measured surface temperature of the die and the set temperature is about +/-20 degrees, the huge temperature difference causes that the product cannot reach the regulation after shaping, the yield is very low, and the yield is only about 50 percent according to the test.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model discloses to the society provide one kind make the die can thermally equivalent, the difference in temperature is littleer, the higher board that generates heat that is used for die casting flattening of yields of the hot plastic of product.

The utility model also provides a make the product can be heated even, the die surface temperature and set for between the temperature difference is less, the high yields of the hot plastic of product shaping mould that is used for the die casting flattening.

The technical scheme of the utility model is that: the utility model provides a board that generates heat for die casting flattening, including the board body and the heating pipe that generate heat, the heating pipe has anodal access point and negative pole access point, the heating pipe is snakelike setting and is in the heating board is internal.

As the improvement of the utility model, the heating pipe includes the copper pipe, sets up heater strip in the copper pipe, and pack heat conduction silicone grease in the copper pipe.

As an improvement of the utility model, the heating plate body is formed by casting.

The utility model discloses an another scheme is: the utility model provides a plastic mould for die casting flattening, includes the upper die base and with upper die base complex die holder, form a appearance chamber that is used for the holding work piece between upper die base and the upper die base be equipped with the board that generates heat above the upper die base be equipped with the board that generates heat below the die holder, the board that generates heat is foretell the board that generates heat.

The utility model discloses owing to including the board body and the heating pipe that generate heat, the heating pipe has anodal access point and negative pole access point, the heating pipe is snakelike setting and is in the heating board is originally internal. The utility model provides a heating pipe snakelike setting is in the heating plate is originally internal for the heating plate body can thermally equivalent, when putting into the plastic mould and using, the temperature difference between actual measurement's mould surface temperature and the temperature of setting for reduces by a wide margin, and hot plastic mould is heated evenly, makes the product in the mould be heated evenly, thereby can make the whole thermally equivalent plastic of product, and the hot plastic yield of product promotes by a wide margin. Therefore, the utility model has the advantages of make the die can thermally equivalent, the difference in temperature is littleer, the yields of the hot plastic of product is higher.

Detailed Description

Referring to fig. 2 to 3, fig. 2 and 3 disclose an embodiment of a heating plate for die casting leveling, which includes a heating plate body 1 and a heating tube 2, wherein the heating tube 2 has a positive electrode access point 21 and a negative electrode access point 22, and in the present invention, specifically, the heating plate body 1 is cast. Heating pipe 2 is snakelike setting and is in the heating plate body 1, the utility model discloses in, it is concrete, heating pipe 2 includes copper pipe 23, sets up heater strip 24 in the copper pipe 23, and pack heat conduction silicone grease 25 in the copper pipe 23. The utility model discloses in, because the heating pipe snakelike setting is in the heating plate body 1 for the holistic heat of heating plate body 1 is even, when using in putting into plastic mould with the board 9 that will generate heat, the temperature difference between actual measurement's mould surface temperature and the temperature of settlement reduces by a wide margin, and hot plastic mould is heated evenly, makes the product in the mould be heated evenly, thereby can make the whole thermally equivalent plastic of product, and the hot plastic yield of product promotes by a wide margin.

The utility model also provides a plastic mould (as shown in fig. 4 and 5) for die casting flattening, a plastic mould for die casting flattening, including upper die base 31 and lower die base 32 matched with upper die base 31, form a holding chamber 30 for holding the work piece between upper die base 31 and upper die base 31, be equipped with heating plate 9 above upper die base 31, be equipped with heating plate 9 below lower die base 32, this heating plate is foretell heating plate 9, fig. 4 is the state diagram that the plastic mould of the utility model is arranged in the oil pressure thermal shaping machine and is used, upper die base 31 and lower die base 32 equally divide and do not heat by corresponding heating plate 9 to carry out thermal shaping to the work piece in holding chamber 30, in the utility model, heating plate 9 is even to the heat transfer of upper die base 31 and lower die base 32, makes upper die base 31 and lower die base 32 be heated evenly, and the temperature difference between the actual measured mould surface temperature and the settlement temperature is little, the product in the die is heated uniformly, so that the product in the cavity 30 can be subjected to integral uniform heating and shaping, and the thermal shaping yield of the product is greatly improved.
