Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a member for tensioning a mold plate for a pin gate.

BACKGROUND ART A conventional pin gate mold plate tensioning member uses a plastic member fitted onto a strength adjustment screw. Therefore, this member must be directly screwed onto the plate. As a result, a threaded portion must be internally provided on the plate side, which is inconvenient not only in terms of work but also in terms of handling. Furthermore, if the threaded portion on the plate side is damaged, there is an inconvenience that the entire plate must be replaced. As described above, conventional members have defects in various aspects such as workability, cost, and operation, and are not practical.

Problems to be Solved by the Invention The problems to be solved by the invention lie in the fact that each part is separated to facilitate assembly, and at the same time, it is attempted to be detachable from the plate as a single part.

Means for Solving the Problems The present invention was devised to solve the above-mentioned problems, and consists of a strength adjustment screw with a hexagonal wrench hole and a plastic material molded into a cylindrical shape. A plastic member and a stop coupler are provided at one end with a rib for preventing misalignment and a cutout surface for preventing rotation on the peripheral surface, and the plastic member and the stop coupler are connected through the strength adjusting screw. All the problems can be solved by making the pin gate mold plate tension member insertable.

Embodiments and Functions FIG. 1 shows a pin gate mold plate tensioning member of the present invention, which consists of three parts: a strength adjustment screw 1, a plastic member 2, and a stopper coupler 3. As shown in the figure, the strength adjustment screw 1 is a threaded rod with a hexagonal wrench hole, the plastic member 2 is made of plastic material molded into a cylindrical shape, and the stopper coupler 3 has a core at one end. A rib 5 for preventing slippage and a cutout surface 4 for preventing rotation are formed on the circumferential surface. Each of these parts is inserted by joining a plastic member 2 and a stopper coupler 3 through strength adjusting screws 1 as shown in the left figure. That is, the tension member P of the present invention can be assembled by inserting the plastic member 2 into the strength adjusting screw 1 and further screwing the stopper coupler 3. 6 is a screw for fixing the coupler 3.

FIG. 2 shows the inventive member in use. First, the tension member P is inserted into the plate 9 of the mold forming machine. For insertion, use the insertion hole 1 of plate 9.
0 with the fixing screw 6. Next, the tension member P is inserted into the screw hole 8 of the plate 7.
and tighten the strength adjustment screw 1 using a hexagonal wrench. Then, stop coupler 3
The diameter of the plastic part 2 is increased by the taper of the joint between the plastic part 2 and the plastic part 2. Further, since the fitting hole 8 of the plate 7 and the insertion hole 10 of the plate 9 have the same diameter, the tightness of the fitting of the tension member P becomes strong and the tensile force is increased. In addition, since the corner of the insertion portion of the fitting hole 8 of the plate 7 is rounded, fitting of the tension member P becomes easy.

Effects of the invention Since the invention is configured as described above, it has the following effects.

A. Since the parts are divided into three parts, each part can be replaced at will.

(a) The proposed tension member can be created by simply assembling each part.

C. Since the plastic member and the stopper coupler have the same diameter, they can be processed in the same process.

D. The locking coupler is provided with ribs to prevent misalignment, so misalignment will not occur when mating.

Since an optical member is used, it can be expanded and contracted by operating the strength adjustment screw 1, and its diameter can be increased by the taper relationship.

Since the locking coupler is provided with a rotation-preventing cutout surface, the locking coupler can be firmly inserted.

From these many specific effects, performance,
It is possible to provide a pin gate mold plate tensioning member that is superior to conventional members in all aspects such as handling, operation, processing, economical, and practical aspects.
