Abstract
The utility model belongs to the technical field of mould structure design, and in particular relates to an automobile foaming mould. The automobile foaming mould comprises an upper mould and a lower mould, wherein electric heating devices are respectively covered on the external surfaces of the upper mould and the lower mould, and the electric heating devices are flexible resistance cloths. According to the automobile foaming mould, the flexible resistance cloths are adopted for substituting hot water tubes and resistance wires, the flexible materials can be easily and uniformly coated on the surface of the mould, and the heating efficiencies of all parts of the resistance cloths are same, so that the mould is heated uniformly, the surface of the foamed product is smooth, and the foaming effect is good.
Description
Technical field
The utility model belongs to the mould structure design field, specifically, relates to a kind of automobile foaming mould.
Background technology
At automobile manufacturing field, the mould structure design is a very important part of design process, and wherein, foaming mould is again one of them branch, also is an important step that forms independent research and development capacity.
In existing automobile foaming mould technical field, often adopt the mode of hot water heating to foam at die surface, namely lay hot-water line on the surface of foaming mould, foam by the expanded material of hot-water line with the heat transferred mould inside in the hot water, adopt the mode of hot-water line heating to have certain limitation, such as, the stringing difficulty, can not be uniformly distributed in mold surface energy, simultaneously, the water temperature of hot water also is difficult to keep constant, all factors all can cause the die surface inequality of being heated, there is the temperature difference, thereby causes foaming product surface not bright and clean, affect attractive in appearance, also can form the foaming substandard products when serious can't use, simultaneously, the foamed time of hot water heating is long, and production efficiency is low.
Based on defects, the patent No. is that the utility model patent of ZL200920167461.2 discloses a kind of automobile foaming mould, adopts the mode at mould outer mold surface distributed resistance line, utilizes resistive conductor to heat.This mode of heating, overcome to a certain extent the limitation that adopts the hot-water line heating to exist, but, the same limitation that has self, such as, there is the space between the resistive conductor, just can cause heating to a certain extent inhomogeneous equally, resistive conductor needs one by one wiring, and step is more loaded down with trivial details, and it is inhomogeneous to connect up easily.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, adapts to the reality needs, and a kind of automobile foaming mould is provided.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of automobile foaming mould comprises upper die and lower die, all is coated with electric heater unit at the outer surface of described upper die and lower die, and described electric heater unit is flexible resistor cloth.
The two-layer up and down of described flexible resistor cloth is insulating barrier, and described insulating barrier inside is heating resistor.
Described insulating barrier is resin bed.
The heating resistor of described insulating barrier inside is the resistor disc that is arranged in order, and is conducting resinl between each resistor disc.
Described resistor disc is identical with the resistivity of conducting resinl.
The beneficial effects of the utility model are:
1. adopt flexible resistor cloth to replace hot-water line and resistive conductor, flexible material lays than being easier at die surface, and can lay evenly;
2. resistance cloth heating efficiency everywhere is identical, and mould is heated evenly, and foaming product surface is bright and clean, and foaming effect is good.
