Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a resin mold apparatus.
[0002]
[Prior art]
In recent years, in order to cope with the diversification of products, resin molds have been used with a mold apparatus having a structure in which various replacement inserts having different shapes are replaced in the same mold.
Hereinafter, a conventional resin mold apparatus will be described with reference to FIG.
FIG. 3 is a cross-sectional view of a main part showing a conventional mold configuration. In the figure, 1 is a replacement insert, 2 is a stripper for projecting a product, 3 is a movable side plate, and the insert 1 is fixed by bolts 6 from its lower surface. Reference numeral 4 denotes a protruding plate, 5 denotes a protruding plate, 7 denotes a protruding rod, and the lower end thereof is sandwiched between the protruding plate 4 and the protruding plate 5 and is fixed. The stripper 2 is fixed to the protruding rod 7 and has a structure in which the product is protruded from the protruding plate via the protruding rod 7. 8 is a mounting plate, 9 is a molded product, 10 is the shape of the molded product after replacement, and 11 is a block that receives the fixing of the insert 1 and the stripper 2 at the time of replacement.
[0003]
Hereinafter, the replacement procedure of the replacement insert in the mold apparatus having the above configuration will be described.
First, the mold is lowered from the molding machine, the stripper 2 and the ejection rod 7 are fixed, the stripper 2 is separated from the ejection rod, and then the mounting plate 8 is moved to move the upper plate 4 and the lower plate 5 Is released, protrudes from the protruding plate 4 and disassembles the rod 7.
[0004]
Next, the bolt 6 fixing the insert 1 is removed from the back surface of the movable side template 3, and the insert 1 and the replacement block 11 are extracted. Nesting is done in the reverse order.
Thus, in the conventional mold apparatus, in order to replace the insert 1, the protruding plates 4 and 5 are disassembled and the protruding rod 7 fixing the stripper 2 is disassembled from the protruding plate 4, and the movable side Since the bolts must be removed from the back surface of the template 3 and the inserts must be removed, the disassembling operation is complicated.
[0005]
[Problems to be solved by the invention]
As described above, the conventional mold apparatus has a problem that the protruding plate needs to be disassembled in order to replace the stripper.
The present invention solves the above-mentioned conventional problems, and provides a resin molding apparatus that can perform nesting replacement without disassembling the protruding plate even when replacing the stripper. For the purpose.
[0006]
[Means for Solving the Problems]
In order to achieve this object, the resin molding die apparatus of the present invention is a resin molding die apparatus having a stripper for projecting a molded product, the stripper for projecting the molded product, an ejection rod for fixing the stripper, and the ejection and nested integral structure having a return spring to the direction protruding the rod for urging the opposite direction, and the movable mold to fix the nest from the front side of the molding surface of the mold, come in contact at the lower end of the ejector rod A resin mold apparatus is constituted by the projecting plate and the fixed mold.
[0007]
According to the present invention, even when the replacement nest and the stripper must be replaced, the replacement nest and the stripper are integrated, and the protruding rod is placed on the protruding plate so that it is fixed. Since the stripper can be operated without disassembling, it is possible to provide a resin mold apparatus that can be replaced in a short time without requiring the operation of lowering the mold from the molding machine at the time of replacement.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The invention according to claim 1 of the present invention is a resin mold apparatus having a stripper for projecting a molded product, the stripper for projecting a molded product, a projecting rod for fixing the stripper, and a projecting direction of the projecting rod. and ejector plate to come in contact with nested unitary construction, and the movable mold to fix the nest from the front side of the molding surface of the mold, the lower end of the ejector rod and a return spring for urging the opposite direction, The resin mold device is composed of a fixed mold, and even if the replacement insert and stripper must be replaced, the replacement insert and stripper are integrated, and the protruding rod is placed on the protruding plate. Since it was placed and placed, it is possible to operate the stripper without disassembling the protruding plate as in the conventional device. Order, without requiring the operation of unloading the mold from the molding machine at the time of replacement, has an action that can be changed by a short time.
[0009]
An embodiment of the present invention will be described below with reference to FIGS.
In FIG. 1, 3 is a movable side mold plate, 4 is on a protruding plate, 5 is below a protruding plate, 8 is a mounting plate, and 9 is a molded product having the same configuration as the conventional apparatus.
12 is a replacement insert, 13 is a stripper, 14 is a return spring, 15 is a protruding rod, 16 is a bolt, and 17 is a cooling pipe.
[0010]
With respect to the resin molding die configured as described above, the replacement procedure and the operation of the die will be described with reference to FIG. As shown in FIG. 2, the interchangeable insert 12 has an integral structure with a stripper 13, a protruding rod 15, and a return spring 14, and the protruding rod 15 is placed in a state where it is placed on the protruding plate 4. It has a structure. Further, the interchangeable insert 12 having an integral structure is fastened from the front side of the movable side mold plate 3 by bolts 16 and fixed to the movable side mold plate 3. When the replacement is performed, the bolts 16 are removed, the replacement insert 12 is freed, and the replacement insert 12 is pulled out from the movable side template front side. The stripper 13 that pushes out the product operates via the sticking rod 15 by the sticking plate 4 and the return is pushed back when the mold is clamped . Cooling pipes can solve the temperature difference problems when replaced it can be cooled replacement nest alone.
[0011]
As described above, according to the present embodiment, in replacement work including a stripper, replacement can be performed without disassembling the protruding plate.
[0012]
【The invention's effect】
As described above, according to the present invention, even when the replacement nest and the stripper have to be replaced, the replacement nest and the stripper are integrated, and the protruding rod is placed on the protruding plate so that it is fixed. Since the stripper can be operated without disassembling the protruding plate, it is possible to provide a resin mold apparatus that can be replaced in a short time without requiring the operation of lowering the mold from the molding machine at the time of replacement.
