Description
Technical field
The present invention relates to the molding technology thereof field of silica gel product more particularly to a kind of forming method of silica gel product with
And molding equipment.
Background technique
In the modern life, silica gel product is very widely used, for example the silica gel on common electronic dictionary, remote controler is pressed
Key, mother and baby's articles, kitchenware and medical instrument etc. etc. do not depend on day along with being non-petroleum product due to silica gel
Benefit petroleum resources in short supply, so that the substitute that silica gel product becomes similar plastic cement products has been trend of the times, application prospect
It is boundless.Therefore, the demand of silica gel product is growing day by day, and requirement of the people to silica gel product is also higher and higher.
The raw material of production silica gel product are mostly solid-state silica gel and liquid-state silicon gel, the use of solid-state silica gel are raw material production
The processing technology of required silica gel product is complicated, processing equipment land occupation is big, operation difficulty is high, and the product produced is not able to satisfy spy
The requirement of different industry, this certainly exists a degree of restriction for industrial volume production, and application prospect also has a degree of office
Limit.It is that raw material make required silica gel product, the production produced using liquid-state silicon gel that another, which is then using liquid-state silicon gel,
Product are able to satisfy special industry if medical treatment, health etc. are to silica gel product due to being unlikely to deform, producing environmental protection, transparency height
High request, to increasingly get the favour of people.
Currently, the use of liquid-state silicon gel being the method that raw material make required silica gel product are as follows: one mold of preparation, the mold
Including cope plate and lower template, cope plate and lower template mold to form product chamber product chamber corresponding with silica gel product；Pass through people
Work mode solidifies liquid silica gel and obtains silica gel product to the intracavitary filling liquid silica gel of the product.
But the solidification time length comparison of liquid-state silicon gel is short, therefore, the silica gel product of each simultaneous processing of mold
Quantity is few, there is a problem of that molding rate is low.In addition, there are product chamber loading mistakes by manual type filling liquid silica gel
More or very few problems, in the case where excessive, causing silica gel product after molding, there are many flashes, in the case where very few,
Silica gel product after molding is caused to be unsatisfactory for the shape requirements of user, and then that there are product qualification rates is low, and stable product quality
The low technical problem of performance.
Summary of the invention
The purpose of the present invention is to provide a kind of forming method of silica gel product and molding equipments, to solve existing silicon
