Description
Technical Field
The utility model relates to a rubber products mould technical field, more specifically are mould that relates to a rubber and metal bonding sample.
Background
The rubber is used as a high-molecular elastomer and is widely applied to the fields of tires, rubber tubes, sealing elements, shock absorption and the like. Because the rubber itself is not very rigid, under some conditions, the rubber is compounded with other materials in order to provide rigidity to the rubber product. Rubber and metal composite articles are common types of composites.
In the way of compounding rubber and metal, there are cold bonding method and direct bonding between rubber product and metal by cold adhesive. The hot vulcanization method is adopted, and the semi-finished rubber material and the metal coated with the adhesive are vulcanized and molded together through a die. The cold bonding method has a relatively simple process, but cannot bond rubber and metal with complex shapes, and the bonding effect of the cold bonding method is not as good as that of the hot vulcanization method. Therefore, in actual production, a hot vulcanization method is generally used.
In the hot vulcanization adhesion of different glue types, different metal materials and different adhesives, the manufactured products have different adhesion effects, so the adhesion effects of the products need to be tested, and in order to facilitate the preparation of a test piece, a mold for bonding samples of rubber and metal is designed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a: in order to solve the problems that the sample is inconvenient to manufacture in the prior art for verifying the bonding effect of different glue types, different metal materials and different adhesives in the hot vulcanization bonding, a mold for bonding the sample by using rubber and metal is designed.
The utility model discloses a realize above-mentioned purpose and specifically adopt following technical scheme: the utility model provides a mould of rubber and metal bonding sample, includes mould and bed die, it is equipped with the last mould chamber of L type to go up the mould below, the bed die top is equipped with the mould chamber under the type that appears, go up the mould chamber and combine to form the mould chamber of echelonment with the I end intercommunication in bed die chamber, it is equipped with the die orifice to go up the mould side.
Further, go up mould and bed die and constitute the mould that the appearance is the cuboid for the mould is more regular, makes things convenient for production and places more.
Further, the mold opening is arranged between the upper mold and the lower mold, and a mold opening cavity with an opening is formed, so that the mold can be opened by using a pry bar and the like more conveniently.
Furthermore, the two sides of the upper die are respectively provided with one or more stripping cavities, so that the contact surface between the cavities is reduced, and the pulp die is more convenient to open.
Furthermore, the bottom of the lower die is provided with a demoulding hole, and the demoulding hole is communicated with the cavity of the lower die and is used for demoulding after the die is punched.
Furthermore, glue overflow grooves are formed in two sides of the communication position of the lower die and the upper die, and after the upper die and the lower die are pressed, redundant glue materials flow out of the cavity, so that collection of the redundant glue materials is facilitated.
The working principle is as follows: the two metal pieces are respectively placed in an upper die cavity and a lower die cavity, rubber is placed above the metal pieces, the dies are combined together, the upper die is heated and pressurized, then the rubber in the die cavities is vulcanized and adhered to the metal pieces, the upper die and the lower die are separated through a die cavity, and then the metal pieces in the die cavities are ejected out through a die release hole.
The utility model has the advantages as follows:
1. the utility model discloses a mould simple structure has solved and has made the sample through the mould, verifies the problem of the preparation of the sample of the bonding effect of different glues kind, different metal material, different viscose agent in the hot vulcanization bonding.
2. Go up mould and bed die and constitute the mould that the appearance is the cuboid for the mould is more regular, makes things convenient for production and places more, drawing die mouth sets up between last mould and bed die, forms one and has an open-ended drawing die cavity, makes can make things convenient for the use of pinch-bar etc. to open the mould more, drawing die cavity respectively establishes one in the both sides of last mould, and a plurality of setting has reduced the contact surface between the cavity and has also made things convenient for the thick liquid mould to open simultaneously more.
3. The bed die bottom is equipped with the drawing of patterns hole, drawing of patterns hole and bed die chamber intercommunication are placed and are being beaten the drawing of patterns after with the mould, the both sides of bed die and last mould intercommunication department are equipped with excessive gluey groove, go up the lower mould and close mould pressurized back, and unnecessary sizing material flows the die cavity, conveniently collects the collection of unnecessary sizing material.
