Abstract

PURPOSE:To prevent the abrasion on the outside circumferential surfaces of plates mounted with dies and to improve the durability thereof by mounting said plates to guiding rods extending in the front, right and left directions of an enclosing flask slidably and clamping the dies from the three directions. CONSTITUTION:A core 39 is fixed to a moving plate 9a in front of an enclosing flask 5, and a pair of dies 41 which form cavities 40 when clamped are fixed respectively to the moving plates 9b, 9c on the right and left sides of the frame 5. Thereafter, oil hydraulic cylinders 10a, 10b, 10c are operated to move the plates 9a, 9b, 9c toward the flask 5. Then the core 39 and a pair of the dies 41 are advanced into cavities through the opening at the front flask 5a of the flask 5 and the openings of the right and left flasks 5b, 5c, and are thereby clamped. A gooseneck mechanism 15 is brought near the holding plate 3 by an oil hydraulic cylinder 14, to press a nozzle part 15' into the recess 37 of a movable plate 35, and further molten metal is cast into the cavities 40 by oil hydraulic cylinders, whereby products 42 are formed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to die-casting, and more particularly to a die-casting machine suitable for thinning a mold by means of a movable mold that moves from three directions to obtain a rigid product.

Conventionally, the die-casting machine that performs this glaze sheathing process is as follows:
Move the mold along the cross-shaped groove formed on the guide plate,
A type of mold clamping at the position where the curves intersect is known.

However, in the die casting machine as described above, when forming the branch that becomes the guide path of the mold, the groove shape is adjusted to the external shape of the mold and the moving plate on which this mold is coated with iron.
However, high processing accuracy is required, and reed molds and
The Ie dynamic plate had the drawback that its outer surface was easily worn out due to simple vibration with the peripheral wall, and its durability was poor.

An object of the present invention is to eliminate the drawbacks of the conventional machines as described above and to provide a die casting machine in which a mold is moved along a guide rod.

The invention will be explained below with reference to the illustrated embodiments.

8gl, Figure 2 shows the die casting machine 1 of the present invention, in which a holding plate 3 is fixed in a ring direction to a bot 2 in which bath water is accommodated, and a gooseneck rock m15 is mounted on the - side of this holding plate. Below that f! 1. The bot 2 is immersed and installed, and the retaining plate 30) is on the other side! 1! A surrounding frame 5 is provided on the base plate 4, on which the plate 4 is arranged substantially horizontally, near the holding plate 3 and at a position opposite to the gooseneck mechanism 15 that sandwiches the holding plate 3. The surrounding frame 5 has two guide rods 6m, two upper and lower, extending from the Au frame 5a to both sides, and two sets of guide rods 6b, 6a1 and 6a1 each consisting of two upper and lower guide rods located to the left of the seat frame 5b, 6a1 and 5e. A guide rod 6b that extends to the right and has a length of 1m consisting of 2 parts above and below.

Links 12a and 12b are pivoted to the lie.

12c, and these links 12
The intermediate S between m, 12b, and 12c is a link 13m whose one end is supported by the support plate 8.

9m, 9b and 9c are respectively pivotally supported at the other ends of the hydraulic cylinders 10
It is designed to move back and forth between the surrounding frame 5 and the support plate 7 depending on the working side of a, 10b, and 10c. In the illustration, 14 is an oil discharge cylinder that brings the Koosneck shell 15 into contact with and separates from the holding 4i3, and 16 is a hydraulic cylinder that injects the bath from the nozzle part of the gooseneck 14115. The surrounding frame 5 has M++ rear frame 5m, 5d has 18 circular openings 18°19, left and right frames 5b, 5c have square openings 20.21, and upper and lower frames 5e.
, 5f have rectangular openings 22 and 23, and these openings 18 to 23 communicate with the opening 17 in the surrounding frame 5.

In the front frame 5a of the surrounding frame 5, there are two through holes 24 at the top and bottom of the space 1.
7, and the guide rods 6& are inserted into these through holes 24 with their ends inserted. In addition, in the front frame 5a of the surrounding frame 5, there are two through holes 2, upper and lower, passing through the left and right sides 8.
5 are bored, and a certain front inner rod 6b is pushed into these through holes 25 to support the intermediate portion. Two upper and lower through holes 26 and 27 are bored toward the location 17 in the left and right frames 5b and 5a of the v5 frame 5, and two holes 26 and 27 are drilled toward the place 17. 6c and the guide rod 6d are identified by pushing their ends S into the through hole 27 of the frame 5C.

As shown in FIG. 6, an annular ring 29 having a core hole 28 formed in the center is fixed to the opening 18 of the front frame 5a of the surrounding frame 5'. Further, the opening 19 of the rear frame 5d of the surrounding frame 5 has an outer M
An annular base plate 31 forming a cooling channel 308 is fixed between II and 1019, and a middle plate 33 in which a latent spout 32 is formed is added to this ring base plate 31. A movable plate 35 is disposed, which is suspended from a connecting plate 34 of a vertical movement mechanism (not shown), and which moves vertically to cut the stool accessories. The retaining plate 3 is attached to the movable part 35.
The gooseneck mechanism 1 advances and retreats through the dazzling opening 36.
A recess 37 for receiving the nozzle 1615' of No. 5, and a recess 37 for receiving the nozzle 1615' of
3Q) A hole 38 communicating with the spout 32 is formed.Next, the operation of the above will be explained.

Add the core 39 to the moving plate 9& in front of the surrounding frame 5,
A pair of molds 41 (sixth
(only one shown in the figure) are fixed respectively.

Hydraulic cylinders 10a, 10b, and 10c are made to move the movable cylinders 9m, 9b, and 9e toward the surrounding frame 5, so that the core 39 and the pair of gold fibers 41 are moved into the inner space of the surrounding frame 5, respectively. The opening 18 of the mold 5a and the openings 21, 21 of the left and right frames are opened to enter the cavity 17 and the mold is clamped. The mold clamping oil discharge cylinder 14 is operated to bring the gooseneck mechanism 15 close to the holding plate 3, thereby pressing its nozzle capital 15' against the quaternary 37 of the movable plate 35, and the hydraulic cylinder 16 is further operated to move the gooseneck mechanism 15 close to the retaining plate 3. A product 42 is formed by inserting f6 yang into.

After this, the hydraulic cylinder 16 and the old pressure cylinder 10
m, 10b, and 10c are operated in reverse, and the gooseneck mechanism 1
5 is separated from the holding plate 3, and the moving plate 9
m, 9b, and 9c are moved toward the support plate 7, thereby bending the core 39 and the pair of molds 41. During this mold enclosing, the product layered on the core 39 is 42 has its shoulder portion engaged with the annular shape a29, and as the core 39 moves, it partially comes off and moves down through the mouth 43 formed on the base plate 4.

As described above, this invention provides a guide rod located in the front and left and right directions on the surrounding frame, and a movable plate on which the mold is sloped on the guide rod is slidably covered with iron to clamp the mold from three directions. As a result, in addition to being able to form a sheathed product, the sparrow-shaped and movable plates can be easily manufactured due to the flexibility of the external shape, and the mold and movable plate can be easily manufactured in the outer circumferential direction. Durability is improved as there is no generation of tags, and the fcll is installed on the left and right frames of the surrounding frame.
Of the two sets of guide rods made up of books, one set of guide rods located at the gooseneck mechanism and the anti-fishing hook was retrieved by one guide rod that passed through the surrounding frame, so the left and right moving plates could be moved to the left and right moving plates. It can be installed so that the movement paths are exactly aligned, and therefore the right mold and the right mold are accurately opposed, which has the effect that no burrs are generated on the product.
