る。[Detailed description of the invention] (a) Conventional state of the art and its problems Conventionally, injection molding molds require one set of molds for each molded product, so it takes many days to manufacture the mold. The cost is high, and replacing the mold in the molding machine requires the installation and removal of the entire extremely heavy mold, which consumes a lot of manpower and time.

を必要とする点では変りはない。 In addition, it is widely used to standardize the material plates that make up a mold and set up the material plates for one mold as a unit (set) as a base set or base unit, but even in this case, each mold is Since the unit that suits the purpose is selected and the mold part is processed and formed for that unit, it is a considerable labor saving compared to making the base itself from a raw material board, but it requires more labor for each mold. - There is no difference in that a base unit is required.

の利点が見い出し難いような状態で行われている
にすぎないものであつた。 Therefore, recently, we have further streamlined mold production.
One way to save labor and reduce costs is to leave the base part as is and form only the mold part into a cassette type or nested type, and when manufacturing a new mold, only the cassette type is created. Attempts are being made to attach the cassette mold to the mold position of the base in an exchangeable manner. Due to the settings of the preparation (mainly for cooling) circuit and the installation position of the ejector pin, there is still no universal cassette mold that can form any mold for any molded product. For extremely simple molds, there is no need for a temperature control circuit, and the setting of the temperature control circuit and the installation position of the ejector pin are changed for each mold, and this is done with some ingenuity. However, this was done in such a way that it was difficult to see any advantage in adopting the cassette type.

ようにしたものである。(b) Purpose of the present invention The present invention was made in view of the above-mentioned circumstances, and an object of the present invention is to enable a cassette mold to be fitted to a base in an exchangeable manner in an injection mold. The base has a special configuration in advance, and the cassette mold also has a special configuration, making it possible to replace the cassette mold to the base and install it extremely easily and precisely, thus forming the desired mold. If multiple cassette molds are provided, the previously used cassette mold can be easily removed and replaced with another cassette mold while the base remains attached to the molding machine. Unlike molded products, it is possible to easily and effectively set the temperature control circuit and install ejector pins for any shape of cavity and core formed in a cassette mold. Regardless of the changes, the cassette type can be used for general purposes.

The cassette mold of the present invention, which forms the cavity and core, is provided, and the cassette mold used previously can be removed and replaced while the base remains installed in the molding machine.

ースB1個で足りることから格段に低減し得る。() Base B and cassette mold C are provided separately, and cassette mold C can be attached to and removed from base B as a type of replacement part, so for example, while base B is installed in a molding machine, cassette mold C can be replaced with cassette mold C. You can easily install, remove, and replace only the
Since mold production only needs to be done on the cassette mold material C', unlike manufacturing the entire mold from the base,
The number of days required for mold production can be significantly shortened, and costs can also be significantly reduced as only one base B is required.
() 成形作業時の金型交換が、カセツト型Cの

提供し得る特徴がある。() In the case of conventional so-called cassette type or nested type simple molds, even though the mold part is cassette type or nested type, the settings of the temperature control circuit and the installation position of the ejector pin are different for each mold. However, in the cassette type of the present invention, as mentioned above, both the base B side and the cassette C side are different from each other. It has a special configuration, and in particular, a plurality of small temperature control holes 7 and 9 are pre-drilled in the cassette cavity fitting plate 1 and the cassette core fitting plate 2 on the base B side. Since a plurality of return guide base loose insertion holes 12 have been drilled in the side mounting plate 5 in advance, all that is left to do for the user is to insert the temperature control small holes 7,
9, connect the cavity 17, core 20 and ejector pin 27 at the position where they are connected and matched.
Temperature control circuit 2 as appropriate according to the shape and position of the
4 and 24 and set up the return guide 15 to form a cassette type C, it is possible to quickly adapt to molded products of any shape, and to set the optimum temperature control circuit, the return guide at the optimum position, and the ejector pin installation. This makes it possible to form extremely precise and strong molds, and thus enables standardization suitable for mass production of the cassette mold of the present invention, which consists of a base B and a cassette mold C, and provides a highly versatile cassette mold. There are features that can provide the following.

In combination with the step part of the cassette core fitting hole 8, it has sufficient durability against injection pressure and mold clamping pressure, and exhibits an excellent effect of not causing bending changes in the mold part. A feature is that the return plate 16 is connected to the cassette core 14 so as not to fall off.
