Abstract

The utility model discloses a die ring plate fixing structure, which comprises a die body, a plurality of ring plates, an angle pin and a screw. The pluralities of ring plates are overlapped and fixed on the die body, each ring plate is provided with an angle pin hole for the angle pin to penetrate through, the angle pin penetrates through the angle pin holes of the pluralities of ring plates and then penetrates into a pin hole of the die body, a step hole is arranged on the other side of the die body corresponding to the pin hole, the step hole is communicated with the pin hole of the die body, and the screw penetrates through the step hole on the die body and is in screw connection with a screw hole arranged on an inserting end of the angle pin. The pluralities of ring plates are fixed on the die body via the angle pin, the inserting end of the angle pin is connected with the screw, and the screw can draw the angle pin towards the inside of the die body, thereby being capable of preventing the angle pin dropping from the die body and leading fixation of the ring plates to be more stable.

Description

Mould ring plate fixed structure

Technical field

The utility model relates to a kind of rubber mold, particularly relates to a kind of mould ring plate fixed structure.

Background technology

The conventional tire mould two-half dies of being made up of upper die body and lower mold body that adopt constitute more.In order to ventilate, a plurality of ring plates are installed on upper die body and lower mold body, utilize the gap between the ring plate to breathe freely.The a plurality of ring plates commonly used and the fixed form of die body have two kinds usually, and a kind of is as shown in Figure 1, passes a plurality of ring plates 2 ' with taper pin 1 ', and a plurality of ring plates 2 ' are fixed on the die body 3 '.This fixed form, because taper pin 1 ' cooperates for inclined hole with die body 3 ', taper pin 1 ' comes off in the inclined hole of die body 3 ' easily, ring plate 2 ' is fixing firm inadequately, and taper pin very easily comes off in producing, and causes mould to weigh wounded.Second kind is as shown in Figure 2, adopt to sell 1 directly to households " pass a plurality of ring plates 2 ", with a plurality of ring plates 2 " be fixed on die body 3 " on.This fixed form sells 1 directly to households " with a plurality of ring plate 2 " between be by the fixing a plurality of ring plates 2 of interference fit ", sell 1 directly to households " with a plurality of ring plate 2 " between become flexible ring plate 2 easily " fix also firm inadequately.

The utility model content

The purpose of this utility model is to provide a kind of mould ring plate fixed structure that is connected firmly.

For achieving the above object, technical solution of the present utility model is:

The utility model is a kind of mould ring plate fixed structure, and it comprises die body, a plurality of ring plate; Described a plurality of ring plate is superimposed to be fixed on the die body; It also comprises taper pin and screw; On each ring plate, offer the taper pin hole that can allow taper pin pass, insert in the pin-and-hole of die body in the taper pin hole that taper pin passes on a plurality of ring plates, on die body, the opposite side corresponding with this pin-and-hole offer shoulder hole, this shoulder hole communicates with the die body pin-and-hole, and described screw passes the screw that shoulder hole on the die body and taper pin penetrate on the end and is spirally connected.

After adopting such scheme, because the utility model is with taper pin a plurality of ring plates to be fixed on the die body, the end that penetrates at taper pin connects a screw again, and this screw can be with taper pin tractive in die body, can prevent effectively that taper pin from coming off from die body, fixing of ring plate is more firm.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Description of drawings

Fig. 1 is a kind of mould ring plate fixed form of commonly using;

Fig. 2 is that another kind is commonly used mould ring plate fixed form;

Fig. 3 is a cutaway view of the present utility model;

Fig. 4 is the exploded view of the utility model taper pin and screw.

The specific embodiment

As shown in Figure 3, the utility model is a kind of mould ring plate fixed structure, and it comprises die body 1, a plurality of ring plate 2, taper pin 3 and screw 4.

Described a plurality of ring plate 2 superimposed being fixed on the die body 1; On each ring plate 2, offer the taper pin hole that can allow taper pin pass, insert in the pin-and-hole 11 of die body 1 in the taper pin hole that taper pin 3 passes on a plurality of ring plates, on die body 1, the opposite side corresponding with this pin-and-hole 11 offer shoulder hole 12, this shoulder hole 12 communicates with die body 1 pin-and-hole 11.

As shown in Figure 4, offer screw 31 on the end of described taper pin 3.Described screw 4 has the shaft shoulder 41, and shoulder hole 12 backs that the spiro tooth part of screw 4 passes on the die body 1 are spirally connected with the screw 31 that taper pin 3 penetrates on the end, and the shaft shoulder 41 on the screw 4 leans on the cascaded surface of shoulder hole 12.

Emphasis of the present utility model just is: adopt the taper pin with screw to be placed through on a plurality of ring plates, use this taper pin of screw tractive again.

The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
