Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a synthetic resin molding device.

(B) Conventional technology Conventionally, thermosetting synthetic resin material such as unsaturated polyester resin was housed in the hopper, and while the hopper was advanced along the front mold of the upper surface opening, the slit shape at the lower end of the hopper was used. The synthetic resin material is discharged in a film shape from the discharge port of the, the synthetic resin material is cast into the front mold, and after the synthetic resin is cured, the synthetic resin product, for example, the counter of the washbasin is manufactured. There is a device to do.

(C) Problems to be Solved by the Invention However, as shown in FIG. 1, a counter of a washbasin is provided with a rising portion at the inner edge of the counter for receiving water splashes and the like. There is.

In the rising portion, when casting the synthetic resin material,
Although it is necessary to cast more synthetic resin material than other flat parts, in conventional synthetic resin casting with a hopper, the synthetic resin material is evenly cast to each part of the front mold, The synthetic resin material in the rising portion is insufficient, and the thickness of this portion is insufficient, which causes an incomplete product.

(D) Means for Solving the Problems The present invention is to store a synthetic resin material in a hopper, and while advancing the hopper along the upper surface of the front mold, form a film from a slit-shaped discharge port at the lower end of the hopper. In a synthetic resin molding device in which a synthetic resin material is discharged onto the front mold to supply the synthetic resin material to the front mold to cure it, a baffle plate is rotatably disposed inside the above hopper, and is moved to the front mold. The present invention relates to a synthetic resin molding device characterized in that the outflow amount of the synthetic resin material can be adjusted.

Further, according to the present invention, when a synthetic resin material flows out to a front mold having a flat surface portion and a groove portion continuously provided on the flat surface portion, a baffle plate is formed by cutting out a portion above the front mold groove portion. Then, an opening for increasing the outflow amount is formed, and a large amount of synthetic resin can flow into the groove through the opening.

(E) Function / Effect According to the present invention, the flow rate and flow rate of the synthetic resin material poured from the discharge port to the front mold can be adjusted by the baffle plate provided above the slit-shaped discharge port of the hopper. it can.

Therefore, if a portion that requires a large amount of synthetic resin material, such as the rising portion, is formed with an outflow increasing opening by cutting off the upper baffle plate and the like so as not to be affected by the baffle plate, It is possible to cast a larger amount of synthetic resin material only on the rising portion than on the flat portion.

In particular, since the baffle plate is rotatable, the flow rate of the synthetic resin material cast on the flat surface portion can be adjusted, so that the synthetic resin material cast on the flat surface portion and the portion requiring a large amount of synthetic resin material can be adjusted. The amount of resin material can be adjusted.

(F) Embodiments A synthetic resin molding apparatus according to the present invention will be described in detail with reference to the drawings. FIG. 1 shows a manufacturing of a wash-basin counter having a rising portion for receiving water splash on the inner edge of the back side. 1 shows a synthetic resin molding apparatus A for carrying out. The synthetic resin molding device A is composed of a front mold 1 having an upper surface opening whose length is in the left-right direction, and a hopper 2 suspended above the front mold 1 so as to be movable left and right.

The front mold 1 is a shallow box shape whose planar shape with the longitudinal direction in the left-right direction is a substantially rectangular shape, and a groove portion 3 for forming a rising portion is formed along one edge of the longitudinal side along the same edge. is doing.

Since the wash counter molded in the front mold 1 is molded in an upside down posture, the surface formed in contact with the upper surface of the front mold 1 becomes the upper surface of the product wash counter, and The rising part of is molded in the groove portion 3 of the front mold 1.

As shown in the drawing, the hopper 2 is a substantially rectangular shape with the longitudinal direction in the front-back direction, and the longitudinal length is approximately the same as the front-back width of the front mold 1.

Also, the lower space between the left and right side walls 4,5 of the hopper 2 is narrowed,
The hopper 2 is formed in a substantially inverted triangular shape when viewed from the front.

Further, a discharge opening 6 in the front-rear direction slit opening downward is provided at the lower end of the hopper 2, and the length of the discharge opening 6 is approximately the same as the front-rear width of the front mold 1. .

Further, the upper surface of the hopper 2 is opened so that the synthetic resin material can be injected into the hopper 2 from here.

In addition, a shutter (not shown in order to avoid complication of drawings) is provided below the discharge port 6 so that the hopper 2 can be opened and closed.
It is designed so that the synthetic resin material injected inside can flow out and be stopped.

Further, a rotatable baffle plate 7 is arranged above the discharge port 6 inside the hopper 2.

That is, the front and rear side walls 8 and 9 of the hopper 2 are inserted from the lower ends of the front and rear side walls 8 and 9 by a predetermined dimension so as to pass through the front and rear side walls 8 and 9 to rotate the rotary shaft 10
The baffle plate 7 formed on the rotating shaft 10 is fixed to one end of the baffle plate 7, and the rotating shaft 10 is operated from the outside of the hopper 2 to set the mounting angle of the baffle plate 7. Can be adjusted arbitrarily.

Then, the inner portion of the baffle plate 7, that is, the portion at the position above the groove portion 3 is cut off to remove the hopper 2
An outflow increasing opening 11 having a predetermined width is provided between the rear side wall 9 and the rear side wall 9.

The embodiment of the present invention is configured as described above, and the table type 1
Prior to the casting of the synthetic resin material into the hopper 2, the shutter of the hopper 2 is closed and the synthetic resin material is injected into the hopper 2.

Then, the mounting angle of the baffle plate 7 is adjusted, the hopper 2 is positioned above the left end of the front mold 1, and the shutter is opened. When the hopper 2 is moved to the right while flowing down, the synthetic resin material is cast on the entire surface of the front mold 1,
In particular, a larger amount of synthetic resin material than the other flat surface portion 12 is cast into the groove portion 3 through the outflow amount increasing opening 11.

Then, after waiting for the cast synthetic resin material to harden, the mold is removed from the front mold 1 to form a wash counter for the product.

As mentioned above, for parts where it is necessary to cast more synthetic resin material than flat parts, such as rising parts such as wash counters, cut the baffle plate 7 above the same part and it will be affected by the baffle plate. Try not to
By allowing a large amount of synthetic resin material to be cast, the baffle plate 7 being rotatable, and the mounting angle of the baffle plate 7 being adjusted, the synthetic resin cast from the discharge port 6 to the front mold. Since the flow rate of the material can be adjusted, the ratio of the amount of synthetic resin material that is cast into the part that requires a large amount of synthetic resin material and the part that does not require a large amount of other synthetic resin material is adjusted. can do.

Therefore, even if the viscosity of the synthetic resin material fluctuates due to fluctuations in air temperature or the like, by adjusting the mounting angle of the baffle plate 7, an incomplete molded product can be appropriately produced in response to the fluctuation. Can be prevented.
