Description

DETAILED DESCRIPTION OF THE INVENTION 11 The present invention relates to polystyrene. The present invention relates to a mold for molding foamed synthetic resin beads such as polyethylene, and more specifically to a mounting device suitable for easy attachment and detachment of a cylinder, such as a raw material filling feeder and a product eject bin insertion sleeve in the mold.

A foamed synthetic resin molding mold consists of the mold, a foamed synthetic resin raw material filling feeder, an eject bin, and other parts.When molding a product, a mold that is compatible with the product is selected, and the mold, filling feeder, etc. are connected and fixed in one piece each time, but in conventional installation to a molding die, after the selected molding die is attached to the base frame of the molding machine, the mold is filled. Screw the feeder using bolts and remove it.

11 inches, so I had to operate the tool to tighten and loosen all the bolts one by one while avoiding accessories such as the multiple eject bins that were protruding from the outside of the mold. In addition, there are a considerable number of filling pieces for each mold, and if all the bolts have to be made as described above, the end face of the raw material-filled feeder cylinder and the
- Coupled with the need to adjust the inner surfaces of the engraving molds to be flush, attachment and detachment work was extremely difficult and took a great deal of time.

Therefore, various studies have been made to deal with these actual situations and to perform efficient attachment and detachment, and improvements have been proposed in Japanese Patent Application Laid-Open No. 56-60230, Japanese Patent Application Laid-Open No. 56-92028, etc.

According to the publication, this improvement is achieved by a combination of a spherical protrusion with respect to the brackets in the i'111N mold and a groove on the bracket side, or a structure using a ball and an eccentric grooved ring. It is intended to be easily attached and detached, and has the effect of significantly shortening the time required for attaching and detaching compared to conventional fixing with a large number of bolts.However, due to the use of a sphere, the sphere rotates, It still has the drawback that the feeder cylinder slides in the spiral groove due to slight vibrations accompanying the operation of the raw material filling feeder, making the fixed position of the filling feeder cylinder unstable.

The present applicant has also been working on various improvements for some time, and has developed a mechanism by which the raw material-filled feeder cylinder 3 can be easily attached to a molding die by first engaging and assembling a pair of coupling members. Proposed.

However, these mechanisms are still susceptible to the effects of micro-vibrations accompanying the operation of the raw material filling feeder cylinder, and there remain some difficulties in fixing them.Thus, the present invention focuses on these drawbacks, and It is an object of the present invention to provide a cylindrical body mounting device that not only allows easy attachment and detachment of filling parts and the like, but also stabilizes the mounting position after mounting.

That is, the present invention is characterized by having an annular hole in the center through which a cylinder such as a raw material filling feeder cylinder of a foam molding mold, an eject bottle insertion sleeve, etc. are inserted, and are connected at the -end. A pair of annular flange members on the mounting side and the fastening side facing each other with an @ mark, the fastening side flange member being passed through the fastening side flange member at the opposite side portion away from the connecting side, and fastening that can be screwed to the mounting side 7 flange member. Using a mounting member provided with a screw, fixing the mounting side flange member to the back plate of the foam molding mold, and tightening the fastening screw through the cylinder inserted through the annular hole. The point is that the flexibility of the II flange member is utilized to fix it to the foam molding die.

Hereinafter, specific aspects of the present invention will be further described in detail. First, the basic principle of the present invention is to attach the fastening side flange member of a pair of annular flange members on the mounting side and the fastening side that are partially connected. By screwing into the side flange member, the gap between both flange members is used to impart flexure to the fastening side flange member, thereby causing the inner surface of the annular hole of the fastening side flange member and the outside of the cylinder passing through it The purpose is to increase the frictional resistance on the circumference and fix it tightly.

Since the bending is used, the diameter of the annular hole of the fastening side flange member can be made slightly larger than that of the cylinder that passes through it, so that the insertion of the cylinder into the annular hole where the mounting part of the cylinder is inserted is possible. Make it easy.

Here, the pair of annular flange members are made of a homogeneous material, for example, made of iron, and a part of the pair of annular flange members is integrally connected. , Molding 5 - Bolt holes that can be fixed to the back plate forming the back plate of the steam chamber of the mold are drilled.

Therefore, the flexure of the fastening side 7 flange member passes through the screw hole provided in the flange surface on the opposite side to the connecting side,
This is done by a fastening screw that is screwed into a thread groove carved in the mounting side 7 lange member, and the screw is screwed into the thread groove,
By tightening it, the required deflection can be obtained.

When attaching a cylindrical body to a mold, such as a feeder, raw material filling feeder, or eject bin insertion sleeve,
These cylinders are passed through the annular hole of the mounting member consisting of the pair of annular flange members, and the mounting side 7 flange members are fixed to the outer wall with bolts, and then the tip of the filling feeder cylinder and the middle surface of the mold Adjust the longitudinal position of the filling feeder cylindrical body so that they are flush with each other, and then tighten the fastening screw at the predetermined proper position.The cylinder can be easily installed due to the frictional resistance between it and the flange member on the fastening side. Complete.

If you fix the mounting member to the back plate in advance using bolts, you can install it by simply passing the cylinder through the annular hole, positioning it accurately, and tightening it with the fastening screw. is completed and more efficient.

Conversely, when removing the cylinder, the fastening side flange member returns to its original state by loosening the fastening bolt, and can be easily pulled out and removed from the mounting member.

Thus, in the mounting device of the present invention, the tightening of the fastener,
The filling feeder cylinder can be easily attached to and removed from the molding die by only loosening operation, and the position of the cylinder is ensured by the increased frictional resistance contact between the inner surface of the annular hole and the outer circumference of the cylinder due to the deflection of the fastening side flange member. This ensures that operations such as raw material filling remain completely stable.
