Detailed Description

Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "front", "rear", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, which are for convenience of description only, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

Example 1:

a rotary type rubber joint vulcanizing mold is mainly composed of a core mold 1 and a rotary mold 3 as shown in FIG. 1, wherein the core mold 1 is located in the inner cavity of the rotary mold 3. The blank of the rubber joint 2 is wound on the core mould 1, and during vulcanization, the blank of the rubber joint 2 is placed into the rotary mould 3 along with the core mould 1.

As shown in fig. 2-3, the rotary die 3 includes a fixed die 31 and two rotary die 32, the two rotary die 32 are respectively hinged to two sides of the fixed die 31 through hinge shafts 33, and the two rotary die 32 are closed after relatively rotating and opened after reversely rotating. In the present embodiment, the included angle between the die surfaces of the fixed module 31 and the two rotating modules 32 is 120 °. As can be seen, the rubber joint 2 only contacts the cavity of the fixed mold block 31 after the mold is opened, and the difficulty in taking out the parts due to airtightness and adhesion is greatly reduced. The two rotary modules 32 rotate to realize die opening and die closing, and compared with the mode of vertically closing the dies, the physical power consumed by an operator is greatly reduced.

Because the positioning mode of one surface and two pins cannot be realized, the rotating die 3 needs to solve the coaxiality problem and the axial dislocation problem of each module after die assembly so as to ensure the integrity of the molding surface of the rubber joint 2. For this, a V-shaped groove 11 is provided at the axial end of the core mold 1, and the fixed block 31 and the rotating block 32 are each provided with an arc-shaped V-shaped projection 321. After the mold is closed, the V-shaped protrusions 321 of the fixed block 31 and the rotating block 32 are caught in the V-shaped ring groove 11. The matching of the V-shaped projection 321 and the V-shaped annular groove 11 positions the coaxiality and axial position of the fixed module 31 and the two rotating modules 32, and the inner cavity surface of the rotating die 3 is free from defects caused by dislocation. Meanwhile, the matching of the V-shaped projection 321 and the V-shaped ring groove 11 positions the coaxiality and the axial position of the rotary die 3 and the core die 1, and prevents the occurrence of uneven wall thickness or other problems of the rubber joint 2.

In this embodiment, the vulcanizing mold needs to be placed into a vulcanizing device for vulcanization. The temperature of vulcanization is higher, in order to prevent that rotary module 32 from opening by oneself, it has pothook 4 to articulate on one of them rotary module 32's the terminal surface, is equipped with card axle 5 on another rotary module 32's the terminal surface, and the back of the compound die, pothook 4 card are on card axle 5, make two rotary module 32 hold tightly. The contact surface of the hook 4 and the clamping shaft 5 has a curved surface similar to a cam, and has great tension after clamping. The clamping structure is very easy to operate manually, and can realize the quick locking of the rotary die 3. Handles are provided on the two rotary modules 32 for ease of opening and closing the molds and for ease of movement.

Example 2:

unlike example 1, as shown in fig. 4, an internal heating device and a vulcanizing device (not shown) are provided in the vulcanizing mold, and the vulcanizing mold itself can be vulcanized without being vulcanized in a vulcanizing facility.

Specifically, an electric push rod 6 is hinged between the fixed module 31 and the rotating module 32, and the electric push rod 6 is used for pushing the rotating module 32 to rotate so as to open or close the die of the rotating die 3. Since the vulcanization is not carried out in the vulcanization equipment, the limitation of the temperature to the use of the electric push rod 6 is avoided. Obviously, the labor intensity of operators can be further reduced by using the electric push rods 6, and the production efficiency is improved.

The present invention is not described in detail in the prior art. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
