Abstract
The utility model discloses a two-die-sinking die, comprising an upper die (1), a middle die (2) and a lower die (3) which are overlapped in sequence, wherein a spring assembly is arranged between the middle die (2) and the lower die (3). The two-die-sinking die is convenient and labor-saving in the process of die release.
Description
Technical field
The utility model relates to vulcanization of rubber field, specifically is a kind of two die sinking moulds that are used in vulcanized rubber products on the vulcanizer.
Background technology
The sulfidation of rubber is meant that unbodied rubber sizing material is under the effect of the vulcanizing agent that mixes with it, the linear polymeric of the inside of sizing material is by being cross-linked to form the elastomeric process of net high-polymer, through this process, unbodied rubber sizing material is shaped to the vulcanized rubber that possesses shape.And suitable temperature and pressure can be accelerated the sulfidation of rubber.Vulcanizer is used for fixing mould exactly, and provides pressure and temperature to the sizing material in the mould, thus the equipment of accelerated cure moulding.
The mould of two die sinkings is meant by three little moulds forms the mould that has two die slots.It comprises stacked successively from top to bottom mold, middle mould and bed die.
The course of work of vulcanizer is: bed die is fixed (as being spirally connected) on cushion cap, pressed down pressing plate then, making a whole set of mould be pressed between cushion cap and the pressing plate and by pressing plate provides sulfuration required heat to mould.
Rubber parts for some shape and size of moulding, this mold also comprises a up-small and down-big core rod, after this just requires sulfuration to finish, elder generation's lifting pressing plate, a whole set of mould is laid down from cushion cap, must be pried open the die slot between bed die and the middle mould then, subsequently middle mould and mold are put upside down, dismantle again screw between core rod and the mold could be pried open mold and middle mould at last.
There is following defective in a kind of two die sinking moulds of above prior art: this two die sinkings mould is to rely on manually to pry open with crowbar fully, must pry open two die slots, and the process of sled mould wastes time and energy.
Summary of the invention
The technical problems to be solved in the utility model is to provide knockout course convenient and strength-saving a kind of two die sinking moulds.
Technical solution of the present utility model is, a kind of two die sinking moulds with following structure are provided, and it comprises stacked successively mold, middle mould and bed die, is provided with spring assembly between middle mould and the bed die.
After adopting above structure, a kind of two die sinking moulds of the utility model compared with prior art have the following advantages:
During sulfuration, bed die is fixed (as being spirally connected) on cushion cap, stacked successively middle mould and mold press down pressing plate then, and the spring assembly place that makes a whole set of mould be pressed between cushion cap and the pressing plate and between middle mould and the bed die pushes against state; And after sulfuration finished, lifting pressing plate, middle mould and bed die just can be thrown off under the effect of spring assembly, subsequently middle mould and mold are put upside down, and the screw between core rod and the mold of dismantling is again pried open mold and middle mould at last.
Owing to be provided with spring assembly between middle mould and the bed die, mould and bed die in automatically springing open, like this, must manually pry open the mould of two die slots with respect to prior art, the utility model two die sinking moulds only need artificial sled once, so laborsaving convenience, and can also satisfy and open the requirement that the die slot between middle mould and the bed die is opened the die slot between mold and the middle mould more earlier.
As improvement, spring assembly is complete, every sleeve spring assembly comprises one first installing plate, second installing plate and a spring, first installing plate is fixed on the sidewall of middle mould, second installing plate is fixed on the sidewall of bed die, and the lower end of spring is fixed on second installing plate, and the upper end of spring is pressed on first installing plate when middle mould and bed die closure, like this, this spring assembly is simple in structure and function-stable is reliable.
As improving, spring assembly is a quadruplet again, along circumferentially be evenly distributed on this two die sinkings mould around, like this, when mould and bed die are thrown off in making stressed evenly.
Description of drawings
Accompanying drawing is that a kind of two die sinking moulds of the utility model are faced structural representation when being installed on the vulcanizer.
Shown in the figure 1, mold, 2, middle mould, 3, bed die, 4, first installing plate, 5, second installing plate, 6, spring, 7, pressing plate, 8, cushion cap.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in drawings, a kind of two die sinking moulds of the utility model, it comprises stacked successively mold 1, middle mould 2 and bed die 3.Be provided with spring assembly between middle mould 2 and the bed die 3.Spring assembly is a quadruplet, along circumferentially be evenly distributed on this two die sinkings mould around.Every sleeve spring assembly comprises one first installing plate 4, second installing plate 5 and a spring 6, first installing plate 4 is fixed on the sidewall of middle mould 2, second installing plate 5 is fixed on the sidewall of bed die 3, the lower end of spring 6 is fixed on second installing plate 5, and the upper end of spring 6 is pressed on first installing plate 4 when middle mould 2 and bed die 3 closures.
In the sulfidation, the cure pressing plate 7 of machine of mold 1, middle mould 2 and bed die 3 is pressed between the cushion cap 8 of pressing plate 7 and vulcanizer, and bed die 3 is spirally connected by the screwed hole and the cushion cap 8 of its bottom.
Claims (3)
1. die sinking mould, it comprises stacked successively mold (1), middle mould (2) and bed die (3), it is characterized in that: be provided with spring assembly between middle mould (2) and the bed die (3).
2. a kind of two die sinking moulds according to claim 1, it is characterized in that: spring assembly is complete, every sleeve spring assembly comprises one first installing plate (4), second installing plate (5) and a spring (6), first installing plate (4) is fixed on the sidewall of middle mould (2), second installing plate (5) is fixed on the sidewall of bed die (3), the lower end of spring (6) is fixed on second installing plate (5), and the upper end of spring (6) is pressed on first installing plate (4) when middle mould (2) and bed die (3) closure.
3. a kind of two die sinking moulds according to claim 2, it is characterized in that: spring assembly is a quadruplet, along circumferentially be evenly distributed on this two die sinkings mould around.
