Description
Technical field
The present invention relates to constructing tunnel waterstop technical field more particularly to a kind of systems for producing rubber fastening band
The preparation method of standby mold and rubber fastening band.
Background technology
Buried water strip is the waterproof material that concrete seam is important in tunnel, is mounted among tunnel double-lining, can be with
It deforms without losing water stopping function with the displacement of tunnel deformation joint, using its sealing and soft feature, water is intercepted
Except two linings.
Current waterstop is all smaller in lateral stiffness, it is easy to be bent.The quality of sealing belt construction is also tunnel water proofing
Pith, at present waterstop construction when, be to erect the side of waterstop, the other side is hanging, be used in combination reinforcing bar clamp general
Waterstop " end " is flat, although ensure that sagging, deformation does not occur in construction for waterstop, increases the construction time, delays
Construction speed virtually increases construction cost, and waterstop is in direct contact with reinforcing bar, this is resulted between waterstop and reinforcing bar
Concrete is difficult closely knit, and the concrete between waterstop and reinforcing bar also easily causes crackle, stomata etc., shadow during upper number
Construction quality is rung, leakage hidden trouble is increased.Remove reinforcing bar clamp, waterstop can be due to its own gravity, it is easy to occur
Sagging, deformation, and during poured concrete, waterstop as impact, flowing and the process of vibrating of concrete and
It shifts, can not thus ensure that the anchored end of waterstop can be anchored completely around in concrete, cause waterstop complete
Performance its water-proof function.Due to non-binding power between waterstop rubber and concrete, after waterstop shifts, make seam crossing
Concrete is thinning, causes " chip off-falling " phenomenon, seriously affects traffic safety.
Waterstop produce vulcanize when, to ensure the presentation quality of waterstop, prevent starved, levels between mold
The sum of semi-finished product film is more than mold cavity thickness, and rubber is fluid state in Pressurized-heated, and extra rubber is needed from mould
Have delivery end outflow, while reinforcing plate can be driven, change origin-location, causes reinforcement plate spacing excessive, substandard product.
Invention content
The purpose of the present invention is to overcome the defects in the prior art, and reinforcing plate can be positioned by providing one kind, be kept away
Exempt from it and changes the preparation method of the rubber waterstop preparation mould of position and rubber fastening band in sulfidation.
Technical solution of the present invention provides a kind of mold for preparing for producing rubber fastening band, including cope plate and lower die
Plate is formed with the die cavity for being used to form rubber fastening band, in the lower template between the cope plate and the lower template
The limit component for being limited to the reinforcing plate in the rubber fastening band, the limit structure are provided on the outside of input terminal
Part is located at the outside of the die cavity.
Further, the limit component is positioning lever；
The positioning lever includes cylindrical base and the end with guiding surface, and the guiding surface is located at close to institute
State the side of lower template.
Further, the limit component be positioning pin, be provided on the positioning pin for the reinforcing plate into
The limiting groove of row limit.
Further, positioning plate is installed on the positioning pin, the limiting groove configuration is on the positioning plate
To on the side of the die cavity.
Further, the backstop there are two being laterally extended on the positioning pin for being limited to the positioning plate
Pin, the positioning plate are held between two pins.
Further, there is the first through hole and be used for the backstop for being used for that the positioning pin to pass through on the positioning plate
The second through-hole passed through is sold, the first through hole is connected to second through-hole.
Further, the upper end of the positioning pin is fastened on by one piece of limiting plate on the cope plate, the positioning pin
Lower end be fastened in the lower template by another piece of limiting plate.
Technical solution of the present invention also provides a kind of mold for preparing using described in any one of aforementioned and carries out production rubber and stop
The preparation method of water band, includes the following steps：
The first step：Bottom semi-finished product film is paved in the die cavity of lower template, reinforcing plate is centrally placed in lower template
Semi-finished product film in, while the reinforcing plate is positioned by limit component, then upper layer is paved in the die cavity of cope plate
Semi-finished product film；
Second step：Cope plate is fallen, cope plate and lower template are molded, by one section of rubber fastening band sulphur with reinforcing plate
Chemical conversion type；
Third walks：Cope plate is lifted, by the last period sulfidization molding and there is the rubber fastening band of reinforcing plate to be fed forward, directly
The posterior edges of reinforcing plate in the rubber fastening band of the last period are extremely moved to the input terminal pre-determined distance apart from lower template；
4th step：Bottom semi-finished product film is paved in the die cavity of lower template again, other one piece of reinforcing plate is placed centrally
In semi-finished product film in lower template, while the reinforcing plate is positioned by limit component, then in the die cavity of cope plate
Inside it is paved with upper layer semi-finished product film；
5th step：Cope plate is fallen, cope plate and lower template are molded, by the latter section of rubber fastening band with reinforcing plate
Sulfidization molding, while the rubber fastening band of the latter section of rubber fastening band with reinforcing plate and the last period with reinforcing plate being vulcanized
It is molded as one；
6th step：Third step, the 4th step, the 5th step process are repeated, successively molding makes, until rubber fastening band reaches
To preset length.
Further, in third step, the posterior edges of the reinforcing plate in the rubber fastening band of the last period are at least
Part is located in the die cavity.
Further, the semi-finished product film is the raw rubber in fluid state.
Using above-mentioned technical proposal, have the advantages that：
By the way that limit component is arranged on the input terminal of lower template, for limiting the reinforcing plate in rubber fastening band
Position can be subjected to displacement to avoid reinforcing plate is mobile on the raw rubber of fluid state, solve reinforcing plate and be placed on rubber fastening band
This intermediate problem, improves the quality of product, and also improve working efficiency.
