Abstract
The utility model discloses a double-mold locking flap curing mold. The double-mold locking flap curing mold comprises an upper mold, a lower mold and a middle mold, wherein seam allowance parts of the upper mold and the lower mold are matched with each other; the middle mold is clamped in the middle of the outer sides of the upper mold and the lower mold; the mold orifice parts of the upper mold and the lower mold are in a step shape; the upper end of the middle mold is matched with the mold orifice part of the upper mold; and the lower end of the middle mold is matched with the mold orifice part of the lower mold. The seam allowance part of the lower mold and the mold orifice part of the lower mold have the mold locking functions, so that the mold is tightly and firmly locked, the cured flap finished product has ultrathin sides; and meanwhile, two parts are subjected to mold locking, so that the wear of the seam allowance part of the lower mold is lightened, and the effective service life of the mold is prolonged; and therefore, the quality of the cured flap finished product is stabilized.
Description
Technical field
The utility model relates to a kind of mould for producing spacer, particularly a kind of cushion belt vulcanization mould of twin-lock mould.
Background technology
Rim strip is the endless rubber belt that the face of closing is not subjected to the wheel rim wearing and tearing for the protection of the inner tube of a tyre.It is loaded between the inner tube of a tyre and the wheel rim, and its middle part is thicker, and two edges are gradually thin from inside to outside.The rim strip outer surface has a center line, the match line when doing to install.Also have a hole on the center line, pass for inner tube valve.
The structure of mould for producing spacer such as Figure of description is shown in Figure 1 at present, the die orifice position 5 of patrix 1 and counterdie 2 is groove type, the locked mode mode of rim strip die orifice is very simple, just play the effect of mould 3 in the chucking, it mainly plays the bead 4 locked mode effect or counterdie, that is to say that counterdie die orifice position 5 does not have the effect of locked mode at all.This locked mode mode is when mould use a period of time, and the locked mode effect that counterdie bead 4 is play when wearing and tearing occurring is just very faint, if the adhesive tape weight of rim strip certainly will cause the edge thickening of rim strip, to such an extent as to affected the quality of rim strip finished product more greatly at this moment.
The utility model content
The purpose of this utility model is to provide a kind of mould that makes tightr in locked mode, more firmly and the cushion belt vulcanization mould of the twin-lock mould that reduces wear.
The technical scheme in the invention for solving the technical problem is: the cushion belt vulcanization mould of twin-lock mould, comprise upper die and lower die and middle mould, the bead of upper die and lower die cooperatively interacts, middle mould is stuck in the middle part in the upper die and lower die outside, it is characterized in that, the die orifice position of described upper die and lower die is stepped, matches with the die orifice position of patrix in the upper end of middle mould, matches with the die orifice position of counterdie in the lower end of middle mould.
Be connected by an inclined plane between the two-layer horizontal plane at described upper die and lower die die orifice position, the angle between described inclined plane and the lower layer of water plane is 105 degree.
The beneficial effects of the utility model are: change the die orifice position of upper die and lower die into staged by traditional groove type, the effect of locked mode has been played at counterdie bead and counterdie die orifice position simultaneously, it is tighter, more firm to cause mold lock to get, the limit section of the rim strip finished product that vulcanizes is also thinner, simultaneously because there being two positions to carry out simultaneously locked mode, therefore the wearing and tearing that alleviated the counterdie bead have prolonged the Acceptable life of mould.Make the quality of the rim strip finished product that vulcanizes obtain stable.
Description of drawings
Fig. 1 is the structural representation of the present cushion belt vulcanization mould that uses;
Fig. 2 is structural representation of the present utility model;
The local structure for amplifying schematic diagram at the die orifice position of Fig. 3 the utility model counterdie.
Among the figure: 1 patrix, 2 counterdies, mould in 3,4 beads, 5 die orifice positions.
The specific embodiment
The utility model will be further described below in conjunction with Figure of description:
As shown in Figure 2, the cushion belt vulcanization mould of twin-lock mould, comprise patrix 1, counterdie 2 and middle mould 3, the bead 4 of patrix 1 and counterdie 2 cooperatively interacts, middle mould 3 is stuck in the middle part in patrix 1 and counterdie 2 outsides, the die orifice position 5 of described patrix 1 and counterdie 2 is stepped, matches with the die orifice position of patrix 1 in the upper end of middle mould 3, matches with the die orifice position of counterdie 2 in the lower end of middle mould 3.
As shown in Figure 3, be connected by an inclined plane between the two-layer horizontal plane at described patrix 1 and counterdie 2 die orifice positions 5, the angle between described inclined plane and the lower layer of water plane is 105 degree.
During use, the effect of locked mode has been played at counterdie bead 4 and counterdie die orifice position 5 simultaneously, it is tighter, more firm to cause mold lock to get, the limit section of the rim strip finished product that vulcanizes is also thinner, simultaneously because there being two positions to carry out simultaneously locked mode, therefore the wearing and tearing that alleviated counterdie bead 4 have prolonged the Acceptable life of mould.Make the quality of the rim strip finished product that vulcanizes obtain stable.
The above, principles more of the present invention just explain through diagrams, this specification be not be the present invention to be confined to shown in described concrete structure and the scope of application, so every corresponding modify that might be utilized and equivalent all belong to the claim that the present invention applies for.
Except the described technical characterictic of specification, all the other technical characterictics are those skilled in the art's known technology.
Claims (2)
1. the cushion belt vulcanization mould of twin-lock mould, comprise upper die and lower die and middle mould, the bead of upper die and lower die cooperatively interacts, middle mould is stuck in the middle part in the upper die and lower die outside, it is characterized in that, the die orifice position of described upper die and lower die is stepped, matches with the die orifice position of patrix in the upper end of middle mould, matches with the die orifice position of counterdie in the lower end of middle mould.
2. the cushion belt vulcanization mould of twin-lock mould according to claim 1 is characterized in that, is connected by an inclined plane between the two-layer horizontal plane at described upper die and lower die die orifice position, and the angle between described inclined plane and the lower layer of water plane is 105 degree.
