Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a pedestal device that receives a core from a molding machine after molding a product and takes it out to the outside of the molding machine.

(Prior art) As a conventional technology, a movable base is provided with a cradle in which a specific core holder member is protruded and fixed to the side.
A horizontal movement mechanism is provided to horizontally move this pedestal between a position between the upper and lower molds of the molding machine and a position on the outside of the molding machine, so that when the upper and lower molds of the molding machine are separated in the vertical direction after molding, For example, there was a structure in which the pedestal was moved to a lower position of the upper mold to catch the core dropped from the upper mold, and then the pedestal and therefore the core were moved horizontally to the outside of the molding machine. .

(Problems to be solved by the invention) In the conventional method described above, a cradle was formed by fixing a specific core holder member to a movable table, so when the core was taken out from the upper mold or the lower mold. ,
A dedicated pedestal must be prepared for each, which increases the number of types of pedestals, which is uneconomical.

The object of the present invention is to obtain a new cradle device for taking out the core of a molding machine that eliminates the above-mentioned drawbacks.

(Means for Solving the Problems) In order to achieve the above object, the present invention is constructed as follows.

That is, a movable base disposed above the base is removably provided with a core receiving member protruding laterally, and an elevating mechanism for vertically moving the movable base with respect to the base; a horizontal movement mechanism that reciprocates the movable base laterally; the elevating mechanism includes a link mechanism that connects a lower part to the base and an upper part to the movable base to move the movable base in parallel with the base; and a drive device that causes the link mechanism to expand and contract.

(Function) Since the present invention has the above structure, if the core receiving member is selected appropriately, the movable platform, lifting mechanism and horizontal movement mechanism can be used in common, and the core can be placed in either the upper mold or the lower mold. It can also be used in take-out formats.

Further, when the horizontal movement mechanism is activated, the movable table and the core receiving member are moved horizontally and reciprocated between the mold section of the molding machine and the outside.

Further, when the elevating mechanism is operated, the movable base and thus the core receiving member move up and down.

In this case, since the core receiving member is moved up and down by the link mechanism, its vertical movement amount becomes large and its lowest position becomes a low position.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

In FIG. 1, 1 is a mold device forming a molding machine, in which a movable platen 3 is arranged above a lower platen 2 on the fixed side so as to be movable up and down, and each platen 2, 3
A lower mold 4 and an upper mold 5 which are horizontally divided are engaged with opposite surfaces of the mold.

6 is a core, which is set so that when the upper mold 5 is divided upwardly from the lower mold 4 after product molding, it is held on the upper mold 5 side and moves upward; In this state, it is released from the upper mold 5 by the operation of a mold release rod (not shown) and is dropped.

Reference numeral 10 denotes a cradle for receiving the core 6, and a plate-shaped or fork-shaped core holder member 10b extending in the left-right direction is removably attached to the left end (in FIG. 1) of the movable base 10a. .

That is, as shown in FIG. 2, a groove 10a-1 with an open upper surface is formed at the left end of the movable table 10a, and a locking piece 10b-1 bent downward is formed at the right end of the core receiving member 10b. A locking piece 10b-1 is removably fitted into the groove 10a-1 from above.

The core receiving member 10b may have a receiving surface 10b-2 of the core 6 formed into a plate shape as shown in FIG. 3, or a receiving surface 10b-2 as shown in FIG.
-3 formed into a fork shape as appropriate movable base 1
It can be attached and detached to 0a.

11 is a horizontal movement mechanism, which is constructed as follows.

That is, as shown in FIG. 1, a base 12 is provided below the pedestal 10 to support the pedestal 10, and wheels 13 are fixedly protruding downward from the lower surface of the base 12.

Then, the cross-feeding cylinder 15 is arranged horizontally, the right end of the cylinder case 15a is connected to a fixed member such as a frame, and the left end of the cylinder rod 15b is connected to the right end of the base 12, so that the reciprocating movement of the cylinder rod 15b The base 12 is reciprocated in the left and right direction.

That is, when the cylinder rod 15b moves toward the left and extends, the pedestal 10 moves horizontally to the left, for example, as shown in FIG. When the cylinder rod 15b is moved to the right and shortened, the pedestal 10 moves horizontally to the right as shown in FIG. It is set so that it is located on the outer right side of .

Further, 16 is a lifting mechanism, which is constructed as follows.

That is, the movable table 10a and the base 12 are connected to each other by an X-shaped link mechanism 17.

This link mechanism 17 rotates each left end of a pair of link arms 17a, which are rotatably connected to each other by a pin P1 at an intermediate portion in the longitudinal direction, to the left end of the base 12 and the left end of the movable base 10a by pins P2, P2. Furthermore, each right end of the link arm 17a is slidably connected only in the horizontal direction to the right end of the base 12 and the right end of the movable base 10a by pins P3, P3 and long holes A, A.

As shown in FIG.
is provided, and the lower end of the cylinder case 18a is rotatably connected to the intermediate portion of the base 12 in the left-right direction with a pin,
Connect the upper end of the cylinder rod 18b to the link arm 17.
A pin is rotatably connected to the lower left side of a.

When the cylinder rod 18b expands and contracts, the movable base 10a of the pedestal 10 and therefore the core receiving member 10b are
is moved up and down outside the molding machine 1 or between the upper and lower molds 5 and 4 of the molding machine.

In this case, in the case of the upper take-out method in which the core is held on the upper mold 5 side and moved upward, the core receiving member 10
As shown in FIG. 3, b is a plate-shaped receiving surface 10b.
-2 to the movable base 10a, and the core receiving member 1
0b is moved upward between the upper and lower molds 5 and 4 of the molding machine so as to approach directly below the core 6 on the upper mold 5 side to receive the core 6 (as shown by the imaginary line in FIG. 5).

In addition, as shown in FIG. 6, when the core is held on the lower mold 4 side and pushed out by the release rod 19, a fork-shaped core receiving member 10b as shown in FIG. 4 is used. Attach the receiving surface 10b-3 to the movable base 10a, and move the core receiving member 10b upward between the upper and lower molds 5 and 4 of the molding machine so that it approaches directly below the core 6 on the lower mold 4 side. and receive the core 6.

In addition, the power reduction of the elevating mechanism and the horizontal movement mechanism may be achieved by using a motor with a speed reducer instead of the cylinder.

(Effects of the invention) As is clear from the above description, according to the invention, the movable base disposed above the base is removably provided with a core receiving member that projects laterally. By appropriately selecting the core receiving member, the movable platform, lifting mechanism, and horizontal movement mechanism can be used in common, and the core can be taken out from either the upper mold or the lower mold.

Therefore, it is possible to obtain a highly compatible and inexpensive pedestal.

Further, since the core receiving member is moved up and down by the link mechanism, its vertical movement amount becomes large and its lowest position becomes a low position.

Therefore, even if the molding machine has a low posture and the core is taken out from the lower mold, the core can be easily carried out from the molding machine.
