Description
Technical field
This utility model is related to silica gel injection molding art, and in particular to a kind of sealing structure of liquid silica gel injection.
Background technology
Liquid silastic also known as LSR, are a kind of liquid conditions of rubber；Liquid silastic injection is a kind of new sealing
Circle processing technique, refers to the processing mode molding by injection by the silicone rubber of liquid, so as to become obturator；Due to the work
Process maintains the advantage of Shooting Technique, and the obturator dimensional accuracy after molding is high, and concordance is good, and sealing function is stable,
It is widely used in the every profession and trades such as automobile, aviation, household electrical appliances, medical treatment.
As the rubber flowing of liquid is very good, part planarity requirements during injection mo(u)lding to being processed are very high
(within 0.01mm), slightly not meeting to make the bad existing picture such as product excessive glue, leak adhesive；Also largely limit just because of this
The development of LSR Shooting Techniques, can only apply in smaller part；Or product plane degree is made by rear manufacturing procedure
Reprocess after up to standard, but the method processing cost is higher.
Utility model content
The purpose of this utility model is：A kind of sealing structure of liquid silica gel injection is provided, can effectively solving liquid silica gel
Leak adhesive in injection or the problems such as excessive glue.
To achieve these goals, this utility model provides following technical scheme：
A kind of sealing structure of liquid silica gel injection, including LSR injection-moulded plastic parts, LSR injection mold sealing parts and sealing
Structure；Arrange on the LSR injection-moulded plastic parts fluted, on the size of the LSR injection molds sealing part and LSR injection-moulded plastic parts
Fit depressions, the bottom surface of the groove is LSR injection sealed glue surfaces, sets in the middle part of the LSR injection molds sealing part lower end
Die cavity is equipped with, the sealing structure of strip in the LSR injection sealed glue surfaces of the LSR injection-moulded plastic parts, is provided with.
Further, the sealing structure in the LSR injection sealeds glue surface is located in the middle part of LSR injection mold sealing parts lower end
Die cavity the left and right sides.
Further, the cross section of the sealing structure is triangle.
The beneficial effects of the utility model are：The sealing structure of this liquid silica gel injection is by being arranged at LSR injection-moulded plastic parts
The sealing structure of bottom portion of groove, the LSR injection sealeds glue surface of LSR injection-moulded plastic parts and LSR injection mold sealing parts when can make injection
Die cavity surround closed area, the problems such as leak adhesive of the effectively solving liquid silica gel in injection or excessive glue.
Description of the drawings
Fig. 1 is a kind of die opening state schematic diagram of the sealing structure of liquid silica gel injection of this utility model.
Fig. 2 is a kind of mold closing view of the sealing structure of liquid silica gel injection of this utility model.
Fig. 3 is a kind of LSR injection views of the sealing structure of liquid silica gel injection of this utility model.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, the utility model is described in further detail.It should be appreciated that specific embodiment described herein is only in order to explaining this
Utility model, is not used to limit this utility model.
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of sealing structure of liquid silica gel injection, it is molded including LSR injection-moulded plastic parts 1, LSR
Mould sealing part 2 and sealing structure 4；Fluted 7 are arranged on the LSR injection-moulded plastic parts 1, LSR injection molds sealing zero
The size of part 2 is engaged with the groove 7 on LSR injection-moulded plastic parts 1, and the bottom surface of the groove 7 is LSR injection sealeds glue surface 3, described
Die cavity 6 is provided with the middle part of 2 lower end of LSR injection mold sealings part, is set in the LSR injection sealeds glue surface 3 of the LSR injection-moulded plastic parts 1
It is equipped with the sealing structure 4 of strip.
Sealing structure 4 in the LSR injection sealeds glue surface 3 is located at the die cavity in the middle part of 2 lower end of LSR injection mold sealings part
6 left and right sides, the sealing structure 4 are used for closing in the middle part of LSR injection sealeds glue surface 3 and 2 lower end of LSR injection mold sealings part
6 area defined of die cavity.
During mold closing, LSR injection mold sealings part 2 is pressed into the groove 7 on LSR injection-moulded plastic parts 1 from the top down,
2 lower end of LSR injection mold sealings part compresses the sealing structure 4 in LSR injection sealeds glue surface 3 final compressive strain excessively, makes LSR
Die cavity 6 in the middle part of 2 lower end of injection mold sealing part forms absolute closing with the LSR injection sealeds glue surface 3 of LSR injection-moulded plastic parts 1
Space.
The cross section of the sealing structure 4 is triangle, wedge angle upward, for convenient in LSR injection mold sealings part 2
Weight under deform, so as to completely enclosed LSR injection mold sealings part 2 and LSR injection sealeds glue surface 3.
After the completion of mold closing, injection moulding process is proceeded by, ultimately form obturator 5 after LSR injections.
Above-described embodiment is used for being further described this utility model, but this utility model is not confined to these
Specific embodiment.All any modification, equivalent and improvement that is made within spirit of the present utility model and principle etc.,
It is interpreted as within protection domain of the present utility model.
