ている。In general, non-metallic tire chains have a three-layer structure consisting of a front rubber layer, reinforcing members such as wire lobes, and a back rubber layer, and spike pins are arranged at predetermined positions. After laminating the sheets of the front side rubber layer and the back side rubber layer made of unvulcanized rubber material and the reinforcing member, and integrally molding the canvas by covering the top surface of the spike pin embedded in the sheet of the front side rubber layer, A method is used in which this is charged into an upper mold and a lower mold and heated under pressure.

あった。In the method described above, in which each constituent member of a non-metallic tire chain is integrally molded and vulcanized, the rubber material flows, causing the spike pin to move or tilt, and the reinforcing member's wire rope and canvas to meander. There was a problem in that defective products were likely to occur due to problems such as poor product quality, and product yields were reduced.

A surface-side coating layer with holes formed therein is molded. Next, the reinforcing member and the spike bottle are inserted into the reinforcing member insertion groove and the spike pin insertion hole of the front side coating layer of the lower mold, respectively, and then the canvas is placed on the top surface of the spike bottle. Next, on top of the front side coating layer in the lower mold, a back side coating layer made of unvulcanized rubber material is placed on top of the upper mold, or the unvulcanized rubber material is placed on the upper mold heated to an appropriate temperature. A back side coating layer formed by press-fitting a sulfur rubber material is placed on the upper mold. Thereafter, it is heated under pressure using an upper mold and a lower mold.

される。In the method for manufacturing a non-metallic tire chain of the present invention, at least the front side coating layer of the front side coating layer and the back side coating layer is molded from a rubber material that is press-fitted into a mold that has been heated to an appropriate temperature in advance. Therefore, the flow of the rubber material of at least the surface side coating layer is suppressed during vulcanization.
以下、この発明の製造方法を、第１図ないし第３図に基
づいて説明する。Hereinafter, the manufacturing method of the present invention will be explained based on FIGS. 1 to 3.
第１図は、表面側被覆層の成形に使用する型と成形時の
状態とを示す線断面図である。FIG. 1 is a line cross-sectional view showing the mold used for molding the surface-side coating layer and the state during molding.
同図において、符号１０は下型、１２は射出用上型、３

ある。In the same figure, numeral 10 is a lower mold, 12 is an upper mold for injection, and 3
0 is the injection ram of an injection molding machine or a transfer molding machine.
下型１０には表面側被覆層成形用溝１１が設けられ、射
出用上型１２には補強部材挿入溝成形用突起１３とスパ
イクビン挿入穴成形用突起１４とが設けである。The lower mold 10 is provided with a groove 11 for forming the surface side coating layer, and the upper mold 12 for injection is provided with a protrusion 13 for forming a reinforcing member insertion groove and a protrusion 14 for forming a spike bottle insertion hole.
あらかじめ下型１０と射出用上型１２とを適宜の温度に
加熱して、射出ラム３０によりゴム材料３２を射出用上
型１２のゲート１５から下型１０内に所定圧力で注入し
て、表面側被覆層を射出成形した後、射出用上型１２を
下型１０から取り外す。The lower mold 10 and the upper mold 12 for injection are heated in advance to an appropriate temperature, and the rubber material 32 is injected at a predetermined pressure into the lower mold 10 from the gate 15 of the upper mold 12 for injection by the injection ram 30, so that the surface After injection molding the side coating layer, the upper injection mold 12 is removed from the lower mold 10.
射出用上型１２が取り外された下型１０内には第２図に
示すように、補強部材挿入溝２１とスパイクピン挿入穴
２２とが形成された表面側被覆層２０が成形されている
。As shown in FIG. 2, inside the lower mold 10 from which the upper mold 12 for injection has been removed, a surface-side coating layer 20 is molded, in which a reinforcing member insertion groove 21 and a spike pin insertion hole 22 are formed.
表面側被覆層２０の射出成形時における下型１０の温度
は８０〜１００°Ｃ１射出用上型１２の温度は５０〜６
０°Ｃの範囲で温度差を設定することが、射出用上型１
２を取り外すときの表面側被覆層２０の離型性の点で最
も適当である。両者の温度が上記の下限温度よりも低い
と射出時におけるゴム材料の流動性がわるくなり、上限
温度よりも高いと後述する加硫時にゴム材料のスコーチ
が進んでゴム合流部にクランクが発生するので好ましく
ない。The temperature of the lower mold 10 during injection molding of the surface-side coating layer 20 is 80 to 100° C. The temperature of the upper mold 12 for injection is 50 to 6° C.
It is possible to set the temperature difference within the range of 0°C for injection mold 1.
This is most suitable in terms of the releasability of the surface-side coating layer 20 when removing the surface-side coating layer 20. If both temperatures are lower than the lower limit temperature mentioned above, the fluidity of the rubber material during injection will deteriorate, and if it is higher than the upper limit temperature, scorch of the rubber material will progress during vulcanization, which will be described later, and a crank will occur at the rubber confluence. So I don't like it.

８を定量重ねる。Next, as shown in FIG. 2, the reinforcing member 24 is inserted into the reinforcing member insertion groove 21 of the surface-side coating layer 20 in the lower mold 10, and then the spike pin 25 is inserted into the spike pin insertion hole 22. Next, the canvas 26 is placed on the top surface of the spike pin 25, and the back side coating layer 2 made of unvulcanized rubber material is placed on top of the campus 26.
Quantitatively overlap 8.

型１６とともに下型１０に被せてもよい。Instead of using an unmolded rubber sheet, the above-mentioned back side coating layer 28 is formed by using an injection mold (not shown) in the upper mold 16 which has been heated to an appropriate temperature in advance, in the same way as the front side coating layer 20. A molded product formed by press-fitting an unvulcanized rubber material may be placed over the lower mold 10 together with the upper mold 16.
上記のようにして加硫された製品を離型して取り出すと

こともなくなる。The non-metallic tire chain of the present invention has a surface coating layer 10.
Of the back side coating layer 28, at least the front side coating layer 10 is in a semi-vulcanized state, which is formed by press-fitting an unvulcanized rubber material into a mold that has been heated in advance to an appropriate temperature below the vulcanization temperature. Therefore, during vulcanization, at least the flow of the rubber material of the surface-side coating layer 10 is suppressed. For this reason, not only does the position of the spike pin 25 inserted into the surface-side coating layer 10 not shift or become tilted, but also the campus 26 that is placed over the spike pin 25 does not meander. spike bin 2
5 can be reliably maintained perpendicularly and at a predetermined position and stabilized, and furthermore, the arrangement position of the reinforcing member 24 can be prevented from meandering.
