Description
Technical field
The present invention relates to mould applications, specific field is a kind of structure for improving polychrome mould product trapped gas.
Background technique
Daytime running lights lampshade mostly uses sealing cover type moulding in modern car light industry, this moulding in injection molding, it is general first at
Type black reshaping Transparent color, this molding mode will appear trapped gas phenomenon in process of production, cause to go out in product sealing glue position
Existing burr increases production cost so as to cause product defect rate rising.
Trapped gas is generally solved the problems, such as by production air discharge duct in the prior art, air discharge duct is generally provided with die joint
Place, and at trapped gas at typeable face, gas can not exclude still cause product trapped gas completely.
Summary of the invention
The purpose of the present invention is to provide a kind of structures for improving polychrome mould product trapped gas, to solve to infuse in the prior art
Molding product is easy the problem of trapped gas.
To achieve the above object, the invention provides the following technical scheme: it is a kind of improve polychrome mould product trapped gas structure,
Including the first upper die and lower die, it is inserted with mold insert in the lower die, the air discharge duct being connected at die joint is offered on the mold insert；
First upper mold matches with the first injection molded layers, and first upper die forming end is equipped with the angle R molding structure, first note
It moulds layer and is forming the angle R with the stitching portion of the second injection molded layers.
Preferably, the mold insert is fixedly connected by pin with lower die.
Preferably, the depth of the air discharge duct is 0.15-0.2mm.
Compared with prior art, the beneficial effects of the present invention are: the application is solved by the way that insert structure is arranged in lower die
It is some because of product trapped gas problem caused by product structure, to meet product appearance requirement；The application is set in the first injection molded layers
The angle R is set, second expects that end flows through at the angle R when being molded formable layer, and rounding off mitigates trapped gas and generates；The processing is simple for this structure, can
Disassembly, later period replacement are convenient and efficient.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the structural schematic diagram of the first injection molded layers in the present invention；
Fig. 3 is partial structure diagram in the present invention.
In figure: 1. lower dies, 2. mold inserts, 21. air discharge ducts, 3. first injection molded layers, the angle 31.R, 4. second injection molded layers, 5. partings
Face.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-3 is please referred to, the present invention provides a kind of technical solution: a kind of structure improving polychrome mould product trapped gas, packet
The first upper mold (not shown) and lower die 1 are included, mold insert 2 is inserted in lower die 1, the exhaust being connected at die joint 5 is offered on mold insert 2
Slot 21；First upper mold matches with the first injection molded layers 3, and the first upper die forming end is equipped with 31 molding structure of the angle R, the first injection molded layers
3 are forming the angle R 31 with the stitching portions of the second injection molded layers 4, as shown in Fig. 2, there is an angle R 31 in end after the molding of the first injection molded layers 3, second
Injection molding material flows through at the angle R 31 when injection molded layers 4 form, and can mitigate trapped gas with rounding off and generate, 2 air discharge duct 21 of mold insert is connected to
At die joint 5, in the molding of the second injection molded layers 4 if end trapped gas, institute's trapped gas body is flowed to point by the air discharge duct 21 on mold insert 2
It is discharged at type face 5, can effectively improve trapped gas problem when multi-colored product injection molding, guarantee that product sealing glue position does not run burr.
Preferably, mold insert 2 is fixedly connected by pin with lower die 1, and installing and dismounting is convenient, convenient for later period replacement maintenance.
Preferably, the depth of air discharge duct 21 is 0.15-0.2mm, and the depth of air discharge duct 2142 is preferably in the present invention
The depth setting of 0.2mm, air discharge duct 21 are suitable, and product sealing glue position can be effectively ensured and do not run burr, while also ensuring that smooth in exhaust.
Working principle: the first upper mold and lower die 1 cooperate, and are molded the first color, form the first injection molded layers 3, the first injection molded layers 3
End forms the angle R 31, is cooperated using the second upper mold (not shown) and lower die 1, is molded the second color, when injected plastics material flows through the angle 31 R,
It can mitigate trapped gas with rounding off and generate, when being molded the second color, the gas that end is stranded is discharged by air discharge duct 21, due to row
Air drain 21 and die joint 5 circulate, and the gas being stranded can drain into die joint 5, the effective trapped gas improved when multi-colored product is molded
Problem.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
