Abstract

PURPOSE:To contrive to manufacture the vessel provided with a partition plate therein even in the case of a large vessel by a method in which a cylinder is arranged in the cylinder fixing hole opening on the bottom surface of a molding recessed portion in such a manner capable of projecting into or retracted from a mold freely, and a push plate is projected into the mold by the cylinder and a rod in two steps. CONSTITUTION:A cylinder 4 and a rod 5 are projected into a mold 1, operating a motor 11 and the cylinder 4, and the central portion of the parison set in the mold 1 is pushed from both sides by a push plate 6. The central portions of the parison 8 facing each other are welded by resin adhesion. Then, the push plate 6 blocks the cylinder fixing hole 3 of a molding recessed portion 2, retracting said plate 6. Next, blowing process is started and the large vessel having a partition plate 15 molded inside is manufactured.

Description

[Detailed description of the invention] [Mosquito control field] The present invention relates to a low-bottom device.

[11r Kyoto Technology J Conventionally, when manufacturing a container with a hollow bottom shape and a +t tension t++ formed inside, the steps shown in Figures 1 and 2 were used.
As shown in the figure, the parison (8) is fully set, and a pair of cylinders (sli41's Drad force 5) are protruded from the mold if) and are freely attached. +51
protrude from each other and press the retaining plate (6) at the base end of the rod (4).
By pressing Parison (8) from both sides, and using that blow to force the comrade in the center to do one blow to Parison (8), and then pushing and blowing Saka (6) back! A container as shown in FIG. 1(d) is formed. However, in this manufacturing method, the thickness of the mold (1) is thin compared to the depth dimension of the recess (2) for cylinder (4) of the mold (1). ) cannot protrude to the rear of its rear gold metal ``i! Insert the cylinder Mi trace hole (1) into the pear shape (7) downwards.
41'E W to open the cylinder presser plate hole 94.
Although it is possible to insert the cylinder (4) into the inside of the canine gorge, the thickness of the cylinder (7) is as thick as 200 to 300 mg during the process of forming the canine gorge. Processing is well 1? ;V It was difficult to eliminate this method.

[Part 1 of the Invention] The present invention has been made in consideration of the above points, and provides a complete blow molding apparatus capable of installing 8 refrigeration units provided with 9 internal partitions even in large containers. This is the same thing that we will provide.

[Disclosure of the invention]

That is, 5 the present invention is a1 of the plan for pool o-1.
] When the layered recess t21 is assembled, it is j% jβ... A syringe hole i31 that opens at the coining of the recess (2) is separately provided in the mold tl), and this syringe attachment hole X (3 ), install the cylinder (4) at will to the inside of the - & Ming i1), and set the lot (5) of the cylinder (4) to the inside of the Kanpashi (1) at will. , when the lot (5) is attached to the tip of the rod (6), extend the parison (8) set in the metal), and insert the cylinder flavored hole into the red hole where the rod (5) is attached. (3) 1) iJ mouth=-
The above-mentioned Ll order J was finally formed using a blow molding machine characterized by the fact that the four presser feet (6) were removed.

The invention will be described in detail below using an example.As shown in Figure 5, there is a concavity (2) in the circle of P0-1. The cylinder flavoring hole (3) that opens to the coining of this storage recess (2) is divided into the cylindrical hole (3), and the round hole (3) has a circular part. A cylindrical body (10) having the shape of
The racks (12+ and A□3) provided on the outside of the cylinder (1o) engage with each other by driving the one-sided body (10) into the mold+.
l) The inward protrusion allows for intrusion. One cylinder (4) is added to bIS of the body (1o), and the cylinder (4) is activated by driving the cylinder (4).
It is an inwardly protruding recessed eye of the 0tsudo (51r fil type +1+).At the tip of the rod (5) is a recessed eye (6).
is marked INN, cylinder (4) and lot (5)
When the presser plate (6) is protruded inward from the mold (1) by driving the presser plate (6), there is a presser plate (6) or a medium size mold (if).
The inside of the parison (8) can be adjusted from both strokes, and the 1yr1 opening of the cylinder seasoning hole (3) can be drilled for the taste of the recessed slope (6). Demeru.

Therefore, in order to install a large-sized Taniju Shishishishi which was made in four parts using the Flow 1 Mogata device thus derived, as shown in Fig. 4, (1st and cylinder [41k i'# UJ and cylinder 1
4] and O. sheet (5) are made to protrude inward of the mold i1),
Center part 2 of the parison (8) set in the firmware if)
Using the presser plate (6), the central part between the parisons U, ``T'', is made into a rice plate by fusing the resin.
Temporarily exhaust the temporary partition (6) and use the cylinder seasoning hole (
3) Open the r base 1 and then start the blowing metal as shown in Figure 1 (d).
It manufactures containers similar to those shown in J. In this way, 48 in total! In the case of J and J, the molding recess (2) is deep and has a recess +3'r.
) even if the protruding mu is a calamity field/meter, cylinder +4
1 and rod (6) in the second stage * by making it a protruding official kakerimesha in the fil, there is no problem even if it is a device in the Taihodani story. Did you hate the above? It is something that can be done. Therefore, only Seishita 111 example 7K (31 is Kinsho tl) has a separate section n.
However, there is no need to process the perforation for the thick finished product (7). The Inuhorotani water obtained in this way has a partition 05) shaped inside it, so the frequency of large empty containers is the same as above, and the number of partitions 1151
This is something that can be combined without using Densou Hari and can destroy Cost Town.

Also, this container can contain 2 types and 9 pieces of gamma.

〔Effect of the invention〕

As described above, in the present invention, a concave shape for the round shape is formed in the inner part of the plan for the hollow molding, and an opening is made in the concave area (9). Attach the cylinder <17 to the clasp mold.
A pun.

Put the cylinder purple gold into the inside of this cylinder with a capacity of 1 inch and 2N, and then put the cylinder cylinder into the inside of the mold. I pressed the parison that was set in the mold on the one area where the cylinder was protruding, and then I placed the opening of the cylinder seasoning hole in the area where the rod had penetrated, so the cylinder and zero were pressed.
By inserting a two-stage molding case into the tsudo, it was possible to make the recess for molding the fil'e wide into a large size in the recess of the Mr. J's shell. Even if the depth of the concavity for the ward shape or the floor of the barrel stand is high, the hole is made to protrude from the inside without any processing, and it is divided into four parts, 9J or 1. It is possible to devise a great solution without any problems.

Claims (1)

[Claims] +1) Form a recess θi- for the cylindrical shape on the inner surface of the mold for the zuro molding, and bud several rows of cylindrical holes in the mold to open at the bottom of the recess for the acid mold, and insert the cylindrical cylinder into the cylindrical housing. At the same time, the rod of the cylinder is allowed to protrude and retract into the inside of the mold. Push aside the parison set in the hole, and install a holding plate to hold the cylinder receptacle (7 holes) until the rod is immersed.
