Abstract

PURPOSE:To mold quickly various weights which are different in shape and size by forming mold holes having required shapes to plural pieces of casting mold blocks having an optional shape and combining an optional number of the casting mold blocks. CONSTITUTION:The casting mold blocks A, B, C having optional shapes are prepd. The mold hole a1 having a bullet shape is formed to the top surface a2 of the block A and the bottom surface a3 is made flat. The mold hole b1 which is triangular on the top surface b2 and is circular on the bottom surface b3 is formed to the proper position from the top surface b2 to the bottom surface b3 of the block B. The mold hole c1 of a circular truncated cone shape is formed to the proper position from the top surface c2 to the bottom surface c3 of the block C. Such blocks A, B, C are combined to constitute the casting mold. A hanging ring hook 2 set with a hanging ring 1 is placed in the hole c2 of the surface c2 of the combined block C and a molten weight material is poured through the hole c1 into the holes b1, a1. The blocks A, B, C and the hook 2 are removed after curing and the weight 3 having the hanging ring 1 is taken out.

Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to a mold for molding weights.

[Prior art]

A mold with left and right hinges has a U-shaped mold hole that is symmetrical on the left and right sides, and the left and right molds are engaged by grasping the gripping rods on the left and right molds, and the mold formed by this engagement is made. There was a weight mold in which melted weight material was injected into the mold hole through the mold hole opening, and after waiting for the injected weight material to harden, the molded weights were removed from the left and right molds.

[Prior art and problems]

With conventional weight molds, you have to grasp the gripping rods of the left and right molds with one hand, and use the other hand to inject the melted weight material into the mold holes, which makes the work difficult and poses the risk of burns. It was heavy, and the quality of the weights made was poor, and -
Only one type of weight could be molded using a set of molds, and in order to make various types of weights for various purposes, various types of molds were required, and the cost of molds was high.

[Purpose of the invention]

The purpose of the present invention is to provide an inexpensive weight mold that solves the above-mentioned conventional problems and can mold weights of various shapes with high quality safely and quickly by freely combining and rearranging simple mold blocks. be.

[Structure of the invention]

In order to achieve this objective, the present invention forms mold holes of a desired shape at appropriate positions in any number of mold blocks of any shape,
Weights of different shapes and sizes can be molded by freely combining and changing the arbitrary number of mold blocks.

[Action of the invention]

To explain the operation based on the configuration of the present invention, when manufacturing a weight of a required shape and size, the required number of mold holes in the mold block, which have mold holes of the required shape in advance, are used to create the weight of the required shape. Combine the mold blocks to form a set of molds, and place the hanging iron hanger at an appropriate position in the mold hole of this mold so that the lower part of the hanging iron hanger will fit into the hole prepared in advance. The molded weight can be taken out by pouring the melted weight material into the mold, waiting for the weight material to harden, and then removing the mold block.

By combining these mold blocks again, a set of molds can be made, and by changing the mold blocks, dozens of types of weights can be molded.

([Embodiments of the invention] Hereinafter, the present invention will be described in detail based on the drawings.

FIG. 1 is a partially sectional perspective view showing three types of mold blocks of the present invention.

Valve-shaped blocks A, B, and C can be formed into arbitrary shapes by using suitable materials such as wood, aluminum, and aluminum. A mold cavity CO,1) is formed, and the lower surface ωD is a flat surface.

Mold holes (bl) are formed at appropriate positions from the upper surface (b2) to the lower surface (h3) of the mold block B, having a triangular shape on the upper surface 6 minutes and a circular shape on the lower surface (ba).

A truncated conical shape (Ct) is formed at appropriate positions from the upper surface (C2) to the lower surface (C3) of the mold block C.

Note that the mold hole (mXbtXCt) of the mold block is not limited to the above shape, and may have a desired shape.

In addition, in order to prevent the mold holes ωIXbrXct') of mold blocks A, B, and C from shifting when the mold blocks are combined or during use, the mold blocks are fitted to each other at appropriate positions in mold blocks A, B, and C. Alternatively, an arbitrary number of suitable holes may be provided in the mold blocks A, B, and C at appropriate positions, and a penetrating rod made of a suitable material is inserted into the hole. σ+Xb+E+) may be prevented from shifting.

FIG. 2 is a perspective view of the mold block of the present invention in use and a perspective view of a weight molded by the combination of this mold block.

The lower surface (ba) of mold block B is assembled on the upper surface (C2) of mold block A, and the upper surface (b
Assemble the lower surface (C3) of mold block C on top of 2). This completes a set of molds.

Hang the hanger (21) made of a suitable material, and place the lower part of the hanger (1) at an appropriate position in the mold hole (C1) of the upper surface (C, z) of the assembled mold block C. Place the Etsuri stopper (2) on the top surface so that it fits, pour the melted weight material into the mold hole (bIXσ2) from the mold hole (cl), wait for the weight material to harden, and then mold blocks A, B, and C. By removing the hanger (2), the molded weight of the hanger can be taken out.

3, 4, 5 and 6 show the upper surface ω0 of the mold block A in FIG. 4 of the present invention, the lower surface (C3) of the mold block A in FIG. In Figure 6, the bottom surface (C3) of mold block A is combined with the bottom surface (ba) of mold block upper block B (ba) to form a soil surface (bz). Although some of the types have been listed above, more than ten types of weights can be molded by freely combining the three types of mold blocks, and by increasing the number of mold blocks, more weights can be molded.

〔Effect of the invention〕

As explained above, the present invention allows more than a dozen types of weights to be manufactured safely, with good quality, and at low cost by simply combining and changing several molding machines. Mold manufacturing can also be simplified and inexpensive molds can be provided.
