Abstract
A kind of clamping cloth membrane die, including punch-pin I, punch-pin II, cavity plate, the punch-pin II is located at I top of punch-pin, the punch-pin II is equipped with fixed ring, there is the handle being fixedly connected on the punch-pin I, cavity plate, there is the positioning pin of interference fit on the punch-pin I, there is the positioning sleeve of interference fit on the cavity plate.The invention has the advantages that reducing the operating time under thermal environment, avoid that sizing material incipient scorch is caused to influence product quality because the operating time is too long.Meanwhile avoiding exchanging preforming tool and the waste of sulfurizing mould bring time and energy waste back and forth, it improves work efficiency.
Description
Technical field
The present invention relates to a kind of mold, especially a kind of clamping cloth membrane die.
Background technique
Clamping cloth diaphragm is widely used in automobile braking device and regulating valve, and clamping cloth diaphragm is mainly by casing play warp-weft same-nature
Cloth and sealant rubber composition.The moulding process major die of the thicker clamping cloth diaphragm of current production is cold-pressed preforming and direct sulphur
2 kinds of methods of chemical conversion type.
Be cold-pressed preforming process method: needing 2 pairs of molds when using technique production clamping cloth diaphragm, a secondary preforming tool and
One secondary sulfurizing mould.Main technique are as follows: first preforming tool is placed on vulcanizing press, preforming tool is secondly opened and puts
Warp-weft same-nature fabric and fixation, the then layer overlay sheet rubber on warp-weft same-nature fabric again can after finally molding compacting a period of time
Rubberized fabric diaphragm semi-finished product of the side of system with glue；Sulfurizing mould is placed on and is preheated to required temperature on vulcanizing press,
It opens mold and is put into preforming good rubberized fabric diaphragm semi-finished product, then be put into one block of rubber above rubberized fabric diaphragm semi-finished product
Piece, then the diaphragm finished product of press cure is heated in molding.The process requirement it is preforming and vulcanization 2 pairs of molds, and include it is pre- at
2 steps of type and vulcanization, temperature is lower when preforming or is room temperature, and temperature is higher when vulcanization, need to heat up back and forth cooling and
Preforming and sulfurizing mould is exchanged, is wasted time and energy consumption；Or need to using the production of 2 vulcanizing presses, one in advance at
One, type, for vulcanizing, needs biggish equipment investment.
Straight forming sulfuration process method: being first to be placed on mold using the clamping cloth diaphragm main operational steps that the technique produces
It is preheated to required temperature on vulcanizing press, opens mold elder generation layer overlay sheet rubber, then puts warp-weft same-nature fabric and fixation
It is good, then put molding heating press cure after one layer of sheet rubber.The technique lower die temperature is higher, puts after first layer rubber because of rubber
Glue and mold cannot be completely attached to and be bonded, and caused rubber to be heat-shrinked asynchronous, led to sheet rubber became uneven, to make to suppress
Clamping cloth diaphragm will appear canvas offset and war proclamation phenomenon；Operating time too long initiation sizing material incipient scorch, reduces the appearance matter of product
Amount and performance.
Summary of the invention
To overcome above-mentioned prior art problem, the present invention provides a kind of clamping cloth membrane dies.
The technical scheme is that a kind of clamping cloth membrane die, including punch-pin I, punch-pin II, cavity plate, the punch-pin II
Above punch-pin I, the punch-pin II is equipped with fixed ring, has the handle being fixedly connected on the punch-pin I, cavity plate, described convex
There is the positioning pin of interference fit on mould I, there is the positioning sleeve of interference fit on the cavity plate.
Further, the punch-pin I, punch-pin II, cavity plate are equipped with gas vent and excessive glue hole in radial same position.
Further, aperture is big on the lower aperture ratio in excessive glue hole on the punch-pin I.
Further, aperture is small on the lower aperture ratio in excessive glue hole on the cavity plate.
Further, the position of the positioning pin and positioning sleeve can be interchanged, i.e., has the positioning of interference fit on punch-pin I
It covers, there is the positioning pin of interference fit on the cavity plate.
The invention has the advantages that reducing the operating time under thermal environment, avoid leading to glue because the operating time is too long
Expect that incipient scorch influences product quality.It avoids exchanging preforming tool and the waste of sulfurizing mould bring time and energy waste back and forth,
It improves work efficiency.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
In figure: 1. punch-pin I；2. punch-pin II；3. cavity plate；4. excessive glue hole；5. gas vent；6. fixed ring；7. positioning
Pin；8. positioning sleeve；9. handle.
Specific embodiment
As shown in Figure 1, a kind of clamping cloth membrane die, including punch-pin I, punch-pin II, cavity plate, the punch-pin II are located at punch-pin I
Top, the punch-pin II are equipped with fixed ring, have the handle being fixedly connected on the punch-pin I, cavity plate, had on the punch-pin I
It is full of the positioning pin of cooperation, has the positioning sleeve of interference fit on the cavity plate, the punch-pin I, punch-pin II, cavity plate are in radial identical bits
Gas vent and excessive glue hole are installed, aperture is big on the lower aperture ratio in excessive glue hole on the punch-pin I, on the cavity plate under excessive glue hole
Aperture is small on aperture ratio.
The position of the positioning pin and positioning sleeve can be interchanged, i.e., has the positioning sleeve of interference fit, the cavity plate on punch-pin I
On have the positioning pin of interference fit.
