Description
Technical field
The present invention relates to a kind of license plate manufacture field, in particular to a kind of mold for processing license plate and removal are molten
The method of wiring.
Background technique
License plate is that having for national vehicle management rules and regulations unifies format, unified pattern, by vehicle management organ
The hard number plate with registration coding that core is sent out after automobile by claiming licence plate is audited, examines, registers.
Auto License plate board is by particular manufacturing craft fusion cast process, however, in fusion-casting process, due to material flow direction and
Amount of flow is different, leads to occur weld bond in license plate, and the performances such as intensity at position with weld bond are poor, are easy to happen
Fracture.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of elimination weld bonds, simple structure and convenient processing
The method processed the mold of license plate and remove weld bond.
To achieve the above object, the present invention provides the following technical scheme that a kind of mold for processing license plate, includes
Lower die and the upper mold that can be fastened with lower die have between upper mold and lower die and are used for fill material and molding licence plate template chamber, on
There is material inlet, it is characterised in that: two material inlets, material inlet are at least offered in the upper mold on mould
There is material diversion chamber between licence plate template chamber, which includes the cavity that can cover upper mold, material diversion chamber
It is connected between licence plate template chamber by several flow-guiding channels, material heating channel is offered in lower die.
By adopting the above technical scheme, material flows into material splitter cavity by multiple and different material inlets, then by several
In the inflow licence plate template chamber of a flow-guiding channel at the uniform velocity, flows into the intracavitary speed and flow of licence plate template and controlled, and object
The flow direction of material can also be consistent, and after being arranged in this way, can still generate a small amount of weld bond.Then it is heated by material logical
Road heats the implementation of licence plate template chamber again, at this time can eliminate the weld bond in incomplete molding license plate.
The present invention is further arranged to: material heats the corrugated setting in channel, and covers entire lower die.
By adopting the above technical scheme, since the flow direction of material cannot be flowed fully according to defined direction, material adds
The passage of heat, which covers entire lower die, to be implemented to heat to entire licence plate template chamber.
The present invention is further set to: lower die be equipped with cooling medium enter channel, the cooling medium enter channel around
Lower die edge.
By adopting the above technical scheme, setting promotes the license plate after heating that can be quickly cooled down in this way, to avoid weld bond
Generation.
The present invention provides a kind of licence plates using the mold for processing license plate in claim 1 to weld line removal side
Method, feature are being that steps are as follows: a, dissolving the material for being used to process license plate implementation, then pass through each object of upper mold
Material inlet is injected separately into；B, material by material inlet enter material diversion it is intracavitary after, at the uniform velocity by several flow-guiding channels
To enter licence plate template intracavitary；C, after licence plate template is intracavitary fill up material after, pass through material heat channel injection heating medium；
D, after the reheating for completing step c, the cooling medium of cooling medium injection lower die is entered into channel；E, it after completing cooling, opens
Mould by molding license plate by the intracavitary taking-up of type, and is chemically treated its surface.
Wherein, heating temperature is 320 DEG C -380 DEG C in step c, and heating time is 5min -8min.
Chemical treatment in step e is that the surface of molding license plate is sprayed antioxidant.
By adopting the above technical scheme, by the above-mentioned means, can promote the surface for the Auto License plate board produced will not generate
Weld bond extends its service life to ensure that the intensity of Auto License plate board.
The invention will be further described below in conjunction with the accompanying drawings.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the embodiment of the present invention.
Specific embodiment
A kind of mold of processing license plate as shown in Figure 1, includes lower die 1 and the upper mold that can be fastened with lower die 12,
Have between upper mold 2 and lower die 1 and be used for fill material and molding licence plate template chamber 3, there is material inlet 21 in upper mold 2,
Two material inlets 21 are at least offered in upper mold 2, and there is material diversion chamber between material inlet 21 and licence plate template chamber 3
4, which includes the cavity that can cover upper mold 2, passes through several between material diversion chamber 4 and licence plate template chamber 3
Flow-guiding channel 5 is connected, and material heating channel 6 is offered in lower die 1.In above scheme, material is injected by multiple and different materials
Mouthfuls 21 flow into material splitter cavities 4, then by flowing into license plate in several flow-guiding channels 5 inflow licence plate template chamber 3 at the uniform velocity
Speed and flow in type chamber 3 is controlled, and the flow direction of material can also be consistent, and after being arranged in this way, can still be produced
Raw a small amount of weld bond.Then channel 6 is heated by material to heat the implementation of licence plate template chamber 3 again, it at this time can will be not complete
Weld bond in complete molding license plate is eliminated.
In embodiments of the present invention, since the flow direction of material cannot be flowed fully according to defined direction, material adds
The passage of heat 6, which covers entire lower die 1, to be implemented to heat to entire licence plate template chamber 3.Material heats the corrugated setting in channel 6, and
Cover entire lower die 1.In order to promote the license plate after heating that can be quickly cooled down, to avoid the generation of weld bond.It is set in lower die 1
There is cooling medium to enter channel 7, which enters channel 7 around 1 edge of lower die.
The present invention provides a kind of licence plates of mold using processing license plate to weld line minimizing technology, and steps are as follows:
A, the material for being used to process license plate implementation is dissolved, is then injected separately by each material inlet of upper mold；B, material by
Material inlet enter material diversion it is intracavitary after, by several flow-guiding channels at the uniform velocity to enter licence plate template intracavitary；C, to
Licence plate template is intracavitary fill up material after, pass through material heat channel injection heating medium；D, after the reheating for completing step c,
The cooling medium of cooling medium injection lower die is entered into channel；E, after completing cooling, die sinking is intracavitary by type by molding license plate
It takes out, and its surface is chemically treated.Wherein, heating temperature is 320 DEG C -380 DEG C in step c, and heating time is
5min—8min.Chemical treatment in step e is that the surface of molding license plate is sprayed antioxidant.By the above-mentioned means,
Can promote the surface for the Auto License plate board produced will not generate weld bond, to ensure that the intensity of Auto License plate board, extend
Its service life.
