Description

The production technology of silicagel pad
Technical field
The present invention relates to the technical field of silicagel pad production more particularly to the production technologies of silicagel pad.
Background technique
Nowadays the pad that hot meal disk is padded on dining table, is typically made into plastic cement, most of this kind of plastic cement is PVC material, it is more heat-resisting.PVC is the material that plasticizer is uniquely used in plastic cement, this allows its state from soft and be bound to hard And it is crisp between change, the especially edge of plastic pad is more crisp easy to wear, is damaged since edge.The life of plastic pad It produces, complex process, step is various, though the plastic pad produced has flexibility, feel is viscous, with after a period of time in the wrong Folding will appear albinism, and elasticity is deteriorated, the lost of life of pad；In addition, the mould structure used when plastic pad produces is complicated And it is heavy, original mold is three-chip type, needs two sides deburring, and when production and processing needs prolonged electrothermal tube to preheat, electric energy Consumption is big, and each product for needing to produce using a large amount of worker's resource is too simple in last quality testing, So that final final product quality substantially reduces.
Summary of the invention
The present invention in view of the existing deficiencies of the prior art, provides a kind of production technology of silicagel pad, can improve silicagel pad Production efficiency and the quality of production.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of production technology of silicagel pad, the silicagel pad include bed of cloth and are respectively arranged on the bed of cloth back side and positive First layer of silica gel and the second layer of silica gel, it is characterised in that：Include the following steps：
Step 1, first time hot pressing：In the first layer of silica gel of back side hot pressing of cloth, semi-finished product silicagel pad is obtained；
Step 2, punching rim charge：Semi-finished product silicagel pad is punched into desired shape；
Step 3, second of hot pressing：Pass through the second silica gel of mould heat pressure in the front for being punched into the semi-finished product silicagel pad come Layer, and the second layer of silica gel is made to cover the side of semi-finished product silicagel pad；The mold includes localization tool, lower template and upper mold Plate, the localization tool are equipped with the positioning through hole being adapted to the size for being punched into the semi-finished product silicagel pad come, and the lower template is set Have and be punched into come semi-finished product silicagel pad shape adaptation type groove, the type groove width be greater than positioning through hole width；Hot pressing When first localization tool is put in lower template, and positioning through hole is made to be located at the surface of type groove, then by semi-finished product silicagel pad from Positioning through hole is put into the type groove of lower template, and after removing localization tool, liquid-state silicon gel is injected into type groove, passes through cope plate heat Press a front surface and a side surface for making liquid-state silicon gel be covered in semi-finished product silicagel pad；
Step 4, feeding：Silicagel pad, deburring are taken out after cooling to be solidified, and finished product silicagel pad can be obtained.
In the above-mentioned technical solutions, first time hot pressing can be infused in the back side of cloth and then hot repressing with solid-state glue or use liquid State silica gel is infused by AB kneading machine in the then hot repressing of the back side of cloth.
In the above-mentioned technical solutions, the silica gel edge of semi-finished product silicagel pad and cloth edge are rushed simultaneously when being punched rim charge It cuts.
In the above-mentioned technical solutions, the positioning through hole upper end of the localization tool is equipped with inclined from the outside to the core import tiltedly Face.
In the above-mentioned technical solutions, the lower template is set there are four type groove, the localization tool be equipped with respectively with four types Corresponding four positioning through hole of slot.
In the above-mentioned technical solutions, the handle that the both ends of the localization tool are equipped with convenient for extracting.
In the above-mentioned technical solutions, second layer of silica gel is the silica gel of the high grade of transparency.
In the above-mentioned technical solutions, first time hot pressing and temperature when second of hot pressing are 120 DEG C.
In the above-mentioned technical solutions, the front and back of the cloth is designed with one layer of dedicated combination glue.
In the above-mentioned technical solutions, the type groove and the range of positioning through hole different widths are 8~10mm.
The present invention has obvious advantages and beneficial effects compared with the existing technology, specifically：1. passing through heat for the first time Pressure, the first layer of silica gel in the back side hot pressing of cloth obtains semi-finished product silicagel pad, in second of hot pressing, semi-finished product silicagel pad The first layer of silica gel the type groove of lower template can be sucked, enable semi-finished product silicagel pad not move, when making hot pressing second layer layer of silica gel Precision is accurate, and flatness is best, and the edge for the semi-finished product silicagel pad for coming out hot pressing is soft to be also not easy wear damage；2. by fixed Position jig is provided with positioning through hole corresponding with type groove, and type groove width is greater than positioning through hole width, and such hot pressing can make Liquid-state silicon gel covers the side of semi-finished product silicagel pad, and semi-finished product silicagel pad is put into the type groove of lower template using localization tool It is interior, liquid-state silicon gel hot pressing is injected after removing localization tool, in this way places semi-finished product silicagel pad more acurrate, hot pressing is more accurate, raw The silicagel pad that output is come is high-quality, and feel might as well；3. simple production process of the present invention, reasonable, environmental protection, and silica gel inherently has There is flexibility, non-toxic and tasteless, strong alkali-acid resistance high temperature resistant is that optimal material is padded in production, elasticity is good for the silicagel pad produced, Good hand touch, flatness is best, is not easy bending deformation, is hardly damaged, and is the silicagel pad that existing public client is liked.
