Abstract
The utility model discloses a kind of gasket silica gel waterproof layer injection molding upper die structures, including cope plate, the cope plate side is symmetrically arranged with two groups of cavity plates, the number of cavity plate described in every group is two, the cavity plate is made of limiting slot and rectangular aperture, the limiting slot is located at rectangular aperture side, and the length and width of limiting slot is all larger than rectangular aperture.The utility model is by being provided with the cope plate of cavity plate, the frame of workpiece is put into cavity plate when being produced, then it is combined cope plate with lower template under the action of hydraulic cylinder, the pressing for just completing workpiece in the process, is then sprayed to silica gel on the substrate of workpiece by rectangular aperture.
Description
Technical field
The utility model relates to molding die technical field, specially a kind of gasket silica gel waterproof layer injection molding upper mold knot
Structure.
Background technique
Silica gel alias silicic acid gel is a kind of high activity adsorbent material, belongs to amorphous substance.Silica gel main component is dioxy
SiClx, chemical property are stablized, do not burn.Since silica gel has good film forming and water resistance, in some electronic products
Accessory, as this gasket being made of frame and substrate of attached drawing 3 production process in, silica gel often does waterproof coating use.Silica gel
Waterproof layer is usually to be machined by silica gel injection molding, and first the gasket processed is put into mold, is then passed through
Silica gel spray-moulding machine then sprays silica gel heating to molten condition by high pressure gas through nozzle, thus in workpiece surface
Form a thin layer of waterproof layer.Although such production technology technology is more mature, process is complex, production efficiency
It is low, if the molding of gasket and the molding of waterproof layer can be integrated, production efficiency will be greatly improved.
For this purpose, we release a kind of higher gasket silica gel waterproof layer injection molding upper die structure of production efficiency to solve
State problem.
Utility model content
It is above-mentioned to solve the purpose of this utility model is to provide a kind of gasket silica gel waterproof layer injection molding upper die structure
The problem of being proposed in background technique.
To achieve the above object, the utility model provides the following technical solutions: a kind of gasket silica gel waterproof layer injection molding
Upper die structure, including cope plate, the cope plate side are symmetrically arranged with two groups of cavity plates, and the number of cavity plate described in every group is two,
The cavity plate is made of limiting slot and rectangular aperture, and the limiting slot is located at rectangular aperture side, and the length and width of limiting slot
Degree is all larger than rectangular aperture.
Preferably, the shape of the limiting slot is identical as workpiece.
Preferably, the cope plate two sides are equipped with guide hole.
Compared with prior art, the utility model has the beneficial effects that the utility model is by being provided with the upper of cavity plate
The frame of workpiece is put into cavity plate by template when being produced, and then makes cope plate and lower template under the action of hydraulic cylinder
It is combined, just completes the pressing of workpiece in the process, then silica gel is sprayed to the substrate of workpiece by rectangular aperture
It is upper.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the cavity die structure schematic diagram of the utility model；
Fig. 3 is the Workpiece structure schematic diagram of the utility model.
In figure: 1 cope plate, 2 cavity plates, 3 limiting slots, 4 rectangular apertures, 5 guide holes.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of gasket silica gel waterproof layer injection molding upper die structure, including upper
Template 1,1 side of cope plate are symmetrically arranged with two groups of cavity plates 2, the number of cavity plate 2 described in every group be two, the cavity plate 2 by
Limiting slot 3 and rectangular aperture 4 form, and the limiting slot 3 is located at 4 side of rectangular aperture, and the length and width of limiting slot 3 is big
In rectangular aperture 4.
Specifically, the shape of the limiting slot 3 is identical as workpiece.
Specifically, 1 two sides of cope plate are equipped with guide hole 5, used for being fixed with rack.
Cope plate is fixed on the rack by guide hole first, the frame of workpiece is put on cavity plate 2 when being produced
Limiting slot in, the substrate of workpiece is put on the punch-pin of lower template, cope plate 1 and lower die are then made under the action of hydraulic cylinder
Plate is combined, and just completes the pressing of workpiece in the process, then silica gel is sprayed to the base of workpiece by rectangular aperture 4
On plate.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
