Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea uses a plurality of molds each consisting of a set of mold pieces to create a mold made of rubber. It also relates to molding equipment that can mold multiple parts made of synthetic resin at the same time. It is something to do.

0002

[Conventional technology]

Molding in which multiple parts made of rubber or synthetic resin are molded at the same time. Conventionally, the mold apparatus shown in FIGS. 4 and 5 is generally known. This molding The mold device 11 is, for example, two molds 12 and 13 arranged side by side on a board 14. The mold 12 is fitted into mutually parallel plate members 14a and 14b, respectively. It is composed of a pair of mold pieces 12a and 12b with a circular cross section, and the other molds 13 are constructed in the same way. has been completed. These mold pieces 12a, 12b are connected to board members 14a, 14b. By driving the pins 15, 15 into the fitting parts with the plate members 14a, 14b, Rotation is stopped.

0003 FIG. 6 shows a molding device 16 according to another conventional example, in which a circle that fits into the board 14 is shown. The molds 17 and 18, each consisting of a pair of mold pieces with a shaped cross section, have square shapes supported on the board 14. It has shaped flange portions 17a and 18a. In this conventional example, the flange The mold 17, 18 is prevented from rotating relative to the board 14. Although not shown, the above pin Conventional examples are also known in which the pin 15 or the pin 19 is replaced with a key.

0004

[Problem that the idea aims to solve]

By the way, in the conventional example, pin 15, pin 19, or a key is not used. Since the molds 12, 13, 17, and 18 are prevented from rotating, pins, keys, etc. Not only does this require additional parts, but it also requires machining of pin holes and keyways, making it difficult to prevent rotation. There was a problem that the structure was complicated and the manufacturing cost was high.

[0005] Furthermore, the molds 12 and 13 or the molds 17 and 18 are compatible with each other on the board 14. Since they are arranged so as not to interfere with each other, the mold devices 11 and 16 including the board 14 There was a problem in that the size tended to become large.

[0006] Therefore, this idea eliminates the need for pins and pin holes for rotation prevention, or keys and keyways. As a result, the rotation prevention structure of the mold can be simplified, and the overall configuration of the device can be made more compact. The purpose is to provide a molding device that can

[0007]

[Means to solve the problem]

In order to achieve the above object, the molding device according to this invention has a set of molding pieces on the board. In a molding device in which a plurality of molds consisting of The method is to provide cut surfaces that join together to prevent rotation.

[0008]

[Effect]

By adopting this method, each mold that fits into the board has a cut surface. By joining each other, rotation is stopped with respect to the board. Therefore, it is necessary to Eliminates the need for parts such as pins and keys to prevent rotation, as well as machining of pin holes and key grooves. This simplifies the rotation prevention structure of the mold.

[0009] In addition, since each mold is fitted to the board with the cut surfaces joined to each other, They are brought closer together, and the overall configuration of the mold apparatus becomes more compact.

【Example】

Hereinafter, embodiments of this invention will be described in detail based on the accompanying drawings. 1 and 2 show a first embodiment of the mold device according to this invention, and the mold Two molds 3 and 4 are arranged side by side on a board 2 of the device 1.

[0011] The mold 3 has a circular section that fits into the mutually parallel plate members 2a and 2b, respectively. It is composed of a pair of mold pieces 3a and 3b with a surface, and the other mold 4 is similarly composed of a pair of mold pieces 3a and 3b with a circular cross section. It is composed of mold pieces 4a and 4b.

0012 Here, the mold pieces 3a and 4a that fit into the board member 2a are bonded to each other. Cut surfaces 3c and 4c are formed, respectively. Similarly, it fits into the board member 2b. Cut surfaces 3d and 4d are formed on the mold piece 3b and the mold piece 4b, respectively, to join each other. has been done.

[0013] Next, the operation of the molding device 1 of the first embodiment configured as described above will be explained. I will clarify. In the mold apparatus 1, a mold piece 3a constituting the mold 3 and a mold piece 3a constituting the mold 4 are The cut surfaces 3c and 4c are formed on the mold piece 4a, respectively, and both the cut surfaces 3c and 4 By joining c, they fit into the board member 2a in a state where they are close to each other. Also By joining the flat surfaces 3c and 4c, they are mutually prevented from rotating relative to the plate member 2a. It is being used. Similarly, the mold piece 3b of the mold 3 that fits into the board member 2b and the mold Cut surfaces 3d and 4d are also formed on the mold piece 4b of No. 4, respectively, and both of them are formed on the cut surface 3d. , 4d are brought close to each other and prevented from rotating relative to the plate member 2b. It is being used.

[0014] Therefore, in the molding device 1, the rotation stopper pins 15, 1 which were conventionally necessary. Parts such as 9 and keys, and machining of pin holes and key grooves are no longer required, and mold 3, The anti-rotation structure of No. 4 is simplified. Also, the molds 3 and 4 are close to each other and on the board 2. Since the board 2 is placed in the The overall configuration of 1 is made more compact.

[0015] FIG. 3 shows a molding device 5 according to a second embodiment of this invention, in which there are Four molds 7, 8, 9, and 10 are arranged side by side in the front, back, left, and right. In addition, the illustration Although omitted, these molds 7, 8, 9, and 10 are also molded in the first embodiment. Similar to types 3 and 4, a set of circular cross sections that fit into mutually parallel plate members, respectively. It is made up of mold pieces.

[0016] Here, the mold 7 on the board 6 has two cut surfaces 7a and 7b at right angles. Similar cut surfaces 8a, 8b, 9a are also formed on other molds 8, 9, and 10, respectively. , 9b, 10a, and 10b are formed. And cut surface 7a and cut surface 8a , cut surface 9a and cut surface 10a, cut surface 7b and cut surface 9b, cut surface 8b By joining the cut surfaces 10b and 10b, the molds 7, 8, 9, and 10 are mutually connected. are placed close to each other on the board 6 and are mutually prevented from rotating relative to the board 6. ing.

[0017] Therefore, in the molding device 5 according to the second embodiment, the rotation that was previously required is also possible. There is no need to process pins 15 and 19 for locking, keys, pin holes, key grooves, etc. , the rotation prevention structure of the molds 7, 8, 9, and 10 is simplified. In addition, molds 7, 8, 9 and 10 are arranged close to each other on the board 6, the board 6 can be made smaller. This allows the overall configuration of the mold device 5 to be made more compact.

[0018]

[Effect of the idea]

As explained above, according to this invention, each mold that fits into the board has a cut surface. By joining each other, rotation is stopped with respect to the board. Therefore, it is necessary to Eliminates the need for parts such as pins and keys to prevent rotation, as well as machining of pin holes and key grooves. Therefore, the rotation prevention structure of the mold can be simplified.

[0019] In addition, each mold piece is fitted to the board with the cut surfaces joined to each other, so it is not possible to The overall configuration of the molding device can be made more compact. .
