Description
Technical field
The utility model relates to a kind of liquid silica gel cold runner dies.
Background technique
In general silicon rubber vulcanization forming technique, refer to that silicone rubber compounds cross generation friendship by heat and other factors
Connection, generating, there is the process of three-dimensional net structure to generate elastomer.Now in silica gel injection molded field, occur some new
Moulding process and cold runner moulding process, silica gel sizing material in runner and cast gate is controlled by certain medium (usually oily)
Temperature makes it remain at curing temperature before entering die cavity hereinafter, make silica gel that good plasticity be kept not cause again
Vulcanization.In article removal, the silica gel material in sprue and runner is still stayed in mold.
Summary of the invention
The purpose of the invention of the present invention is to provide a kind of liquid silica gel cold runner dies.
It is as follows that the utility model solves the technical solution that above-mentioned technical problem is taken:
A kind of liquid silica gel cold runner die, comprising: bottom cover (1), cylinder (2), moving piston (3), needle (4), runner
(5), wet part (6), fortune water jacket (7), valve nozzle (8) are spirally transported, valve nozzle (8) is set to the front end of fortune water jacket (7), and transports water jacket
Inside has channel, and spiral fortune wet part (6) of inside setting, the end of fortune water jacket (7) is connected with runner (5), runner
(5) there are needle (4) in, in addition, being connected with moving piston (3) on the needle (4), and the upper end of moving piston is cylinder
(2), cylinder upper end is bottom cover (1).
Preferably, the needle is height-adjustable structure, based on the upper-lower height of pressure control needle, the valve
Needle can up and down or front and back control stroke comes shooting and sealing.
Preferably, the valve nozzle is directly directed at product type chamber.
After the utility model takes above scheme, use cold runner into glue, after the completion of injecting glue, needle-valve sealing, relatively
Can saving material for the prior art without runner, molding time is short, and high production efficiency, active needle-valve sealing system, injecting glue is more
Precisely, while product periphery is vented, and can satisfy multistation production requirement, and mold mold changing is convenient and simple, and yield is high, overlap
It is small, and easily clear up.
Other features and advantages of the utility model will illustrate in the following description, also, partly from specification
In become apparent, or understood and implementing the utility model.The purpose of this utility model and other advantages can pass through
Structure specifically indicated in the written description, claims, and drawings is achieved and obtained.
Detailed description of the invention
The utility model is described in detail with reference to the accompanying drawing, so that the above-mentioned advantage of the utility model is more
It is clear.
Fig. 1 is the structural schematic diagram of the utility model liquid silica gel cold runner die.
Specific embodiment
The utility model is described in detail combined with specific embodiments below.
As shown in Figure 1, a kind of liquid silica gel cold runner die, comprising: bottom cover (1), cylinder (2), moving piston (3), valve
Needle (4), runner (5) spirally transport wet part (6), fortune water jacket (7), valve nozzle (8), before valve nozzle (8) is set to fortune water jacket (7)
End, and transport with channel inside water jacket, spiral fortune wet part (6) of inside setting, the end for transporting water jacket (7) is connected with stream
Road (5), runner (5) is interior to have needle (4), in addition, being connected with moving piston (3) on the needle (4), and moving piston is upper
End is cylinder (2), and cylinder upper end is bottom cover (1).
Preferably, the needle is height-adjustable structure, based on the upper-lower height of pressure control needle, the valve
Needle can up and down or front and back control stroke comes shooting and sealing.
Preferably, the valve nozzle is directly directed at product type chamber.
After the utility model takes above scheme, use cold runner into glue, after the completion of injecting glue, needle-valve sealing, relatively
Can saving material for the prior art without runner, molding time is short, and high production efficiency, active needle-valve sealing system, injecting glue is more
Precisely, while product periphery is vented, and can satisfy multistation production requirement, and mold mold changing is convenient and simple, and yield is high, overlap
It is small, and easily clear up.
More specifically, in embodiment, for liquid-state silicon gel using conventional injecting glue, conventional injecting glue is doing by heating at present
Method guarantees that the sizing material of runner and cast gate is kept molten by, generally by several parts such as hot nozzle, flow distribution plate, temperature control box and attachment
Composition, since form of nozzle is directly contacted with front cavity, due to the heat cured feature of liquid-state silicon gel, silica gel when entering runner just
Start to solidify, silica gel heat is obstructed, and will result in silica gel poor fluidity, and product appearance plays insatiable hunger, lacks the bad phenomenons such as material.
The utility model takes after above scheme, it is not necessary to can use spot pouring mouth, also, mould with shree plates mold
Has simple to install, without connecing electronic valve, the upper mold time is short, improves working efficiency.Meanwhile silicon rubber vulcanization range is balanced, multimode
The ejection formation part uniform quality of cavity mould.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
