大型化し高価なものとなつた。又、一つの金型で
多数の同時成型方式を採用する現在では、個々の
製品はバリでつながつて金型から取り外される。Conventional technology In the past, in response to the increasing demand for rubber products, large molds with many molding holes were used to simultaneously produce a large number of products, and as a result, the hydraulic mechanisms for pressurizing and heating became larger and more expensive. Summer. Furthermore, in today's world where a single mold is used to mold multiple products simultaneously, the individual products are connected by burrs and then removed from the mold.
その利点は取り外し作業，検査，計数，運搬等
の作業を容易にするが、その反面バリは材料の屑
化であり、それを除去する仕上作業の手間が大き
い。 The advantage of this is that it facilitates work such as removal, inspection, counting, and transportation, but on the other hand, burrs turn the material into scraps, and the finishing work to remove them is time-consuming.
その材料損失と仕上手間の合計金額は製品販売
価額の約10％に迄も至るものと推定される。 The total amount of material loss and finishing time is estimated to amount to about 10% of the product's selling price.

品を取り出すものである。Embodiment An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal cross-sectional side view of the present invention. , a state in which mold fixing frame grooves 4 and 5 and mold opening frame grooves 6 and 7 are provided above and below, respectively, and U-shaped mold fixing frames 8 and 9 are inserted into each of the fixing frame grooves 4 and 5. Figure 2 shows the state when the mold is opened on a mold opening machine.The U-shaped mold fixing frames 8 and 9 are removed, and the claws 10 and 11 fixed at the bottom of the mold open the lower mold 3.
It fits into the mold opening frame groove 7, and the upper claws 12, 13
is fitted into the mold opening frame groove 6 of the upper mold 2 and raised by an appropriate hydraulic mechanism to open the mold and take out the molded rubber product.
効 果
本考案は上述の実施例の如く構成された結果次
のような効果が生じる。従来ゴム製品の製造に必
要な圧力は通常40Kg／cm2と考えられ、50cm角2500
cm2のプレスの耐圧力は安全計算で150屯に耐える
プレスが必要とされていたが、本考案はこれを型
固定枠８，９で上下型固定枠溝４，５に嵌合し、
只単に型が内圧で開くのを阻止するだけで成型さ
せる事に成功したものである。Effects As a result of the present invention configured as in the above embodiment, the following effects are produced. Conventionally, the pressure required to manufacture rubber products is usually considered to be 40Kg/ cm2 , and 50cm square 2500
The safety calculation required a press that could withstand a pressure of 150 tons per cm2 , but in this invention, the mold fixing frames 8 and 9 were fitted into the upper and lower mold fixing frame grooves 4 and 5.
This was achieved by simply preventing the mold from opening due to internal pressure.
従来耐圧150屯の油圧プレスを絶対必要とする
多数個取りの50cm角の金型等を使用した量産方法
を採する限り止むを得ないが、注目すべきはその
必要時間が、５分サイクルの加硫成型でも20分サ
イクルの加硫成型でも加圧は１分で終了すること
である。 Conventionally, it is unavoidable to use a mass production method using multi-cavity 50 cm square molds, which absolutely requires a hydraulic press with a pressure resistance of 150 tons, but it is noteworthy that the required time is 5 minute cycles. Whether it is vulcanization molding or vulcanization molding with a 20-minute cycle, the pressurization is completed in one minute.
従来100屯プレスは成型圧力を加えた後でもそ
の圧力を加硫終了迄維持している。 Conventional 100 ton presses maintain that pressure until the end of vulcanization even after applying molding pressure.
又、成型の終つた弾性体ゴムにその高圧持続の
必要があるかどうか疑問であつた。 In addition, there was a question as to whether it was necessary to maintain the high pressure for the elastic rubber that had been molded.
現在プレスの油圧ポンプは停止し、圧力はバル
ブで止められ150〜200Kg／cm2を示す圧力計の圧力
が保持されている。 Currently, the press's hydraulic pump is stopped, the pressure is stopped by a valve, and the pressure on the pressure gauge is maintained at 150 to 200 kg/cm 2 .
但し加圧は継続していないのでゴム成型に必要
と考えられている圧力は油圧プレスを用いなくと
も保持が可能であることに着目し、本考案は単に
型に圧力を加えるのでは無く、型が開かないよう
に固定するだけで足りる軽量で安価なバリを必要
としないゴム製品製造用金型の考案である。 However, since the pressure is not continuous, we focused on the fact that the pressure considered necessary for rubber molding can be maintained without using a hydraulic press, and the present invention does not simply apply pressure to the mold, but rather This is a lightweight, inexpensive mold for manufacturing rubber products that does not require burrs and only needs to be fixed to prevent it from opening.
