Description

Simple and easy full sample wood pattern

Technical Field

The utility model belongs to the technical field of the casting, in particular to simple and easy real appearance wood pattern.

Background

Patterns, typically made of wood, plastic, metal or other materials, are the tooling used to form the mold cavities. During production, sand is filled around the pattern and compacted, a cavity of a casting mold is formed after stripping, and the appearance profile of the casting is manufactured after pouring molten metal. To ensure the quality of the cast, the pattern must have sufficient strength and rigidity, smooth surface, and precise dimensions.

In the prior art, the method belongs to a single-piece small-batch operation mode, a pattern is made of wood generally, and the pattern is also called a wood pattern. Compared with the patterns made of other materials, the wood pattern has the advantages of light weight, short production period and easy processing and forming. However, if a single small-lot heavy and large-scale casting is manufactured by using an integral solid wood model, on one hand, a large amount of wood is consumed, the manufacturing period is long, and in addition, the wood model can not be used after being used once, so that the economy is poor.

Disclosure of Invention

The utility model aims at providing a compare simple, convenient simple and easy full pattern wooden model with prior art, this simple and easy wooden model not only has sufficient intensity and rigidity, and the timber that consumes is few moreover, and production cycle is short, and economic nature and efficiency all promote more than the twice.

Simple and easy real appearance wooden model's structure as follows: the upper cover plate and the lower cover plate are respectively arranged above and below the rib belt to form a plate belt frame, namely, one section of the periphery of the simple wood mold is provided with a connecting plate connected with adjacent wood molds, the four plate belt frames are connected end to end and are fixedly connected through screws, the contact positions of the adjacent plate belt frames are provided with draft angles, and clamping plates are laid on the side surfaces of the plate belt frames.

Simple and easy real appearance wood former for can dismantle the building block structure of assembling, carry out the concatenation of taking building block form according to product shape and size and form required size shape. The connection mode can be simultaneously applied to the connection reinforcement in the length direction, the width direction and the height direction.

The utility model provides a simple and easy full pattern wood pattern not only intensity and rigidity can satisfy the needs of casting scene, compare with the whole pattern of preparation among the prior art moreover, and whole pattern among the prior art forms through the mutual overlap joint of multilayer flitch and plank, and the utility model discloses a full pattern wood pattern is for dismantling the building block structure of assembling, carries out the concatenation formation required size shape of building block form according to product shape and size. The wood consumption is reduced by half, the manufacturing period is also half of the whole pattern manufacturing period, and in addition, the simple wood pattern is convenient for realizing the modularization of pattern manufacturing.

Fig. 3 the utility model discloses slab band frame construction in the simple and easy real appearance wooden model.

1 in FIG. 2_-1、1_-2、1_-3、1_-4The wood pattern is a plate belt frame around the wood pattern, 2 is a rib belt, 3 is a lower cover plate, 4 is an upper cover plate, 5 is a connecting plate, and 6 is a clamping plate.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

FIG. 1 is a structural form of an integral full-sample wood model in the prior art; the whole pattern is formed by mutually lapping a plurality of layers of battens and wood boards.

Fig. 2 is the simple solid wood pattern structure of the present invention. The real sample wood model is a building block structure which can be disassembled and assembled, and building blocks are spliced according to the shape and the size of a product to form a required size and shape. The rib belt 2 at one end of the plate belt frame and the connecting plate 5 at the other end of the adjacent plate belt frame are fastened and reinforced by a screw (the screw penetrates through the position with holes in the figures 2 and 3) so as to ensure the dimensional accuracy and the strength of the outer die, and the connection mode can be simultaneously applied to connection reinforcement in the length direction, the width direction and the height direction.

plate belt frame 1 around wood mould_-1、1_-2、1_-3、1_-4The rib belt is manufactured in a segmented mode, an upper cover plate 4 and a lower cover plate 3 are respectively arranged on the upper surface and the lower surface of the rib belt 2 to form a section of the periphery of a wood mold (as shown in figures 2 and 3), and a connecting plate 5 connected with an adjacent wood mold is arranged at one end of the rib belt to form a framework outer module (namely a plate belt framework) with the thickness of 180-200 mm. The specific manufacturing method of the wood pattern comprises the following steps: four plate and strip frames 1_-1、1_-2、1_-3、1_-4The end to end connection is realized, the contact part of the adjacent plate and strip frames is provided with a drawing slope of 15 mm-30 mm, and the adjacent plate and strip frames are connected and fixed through a screw, as shown in figure 2. The rib belt 2 is distributed between the upper cover plate 4 and the lower cover plate 3, a connecting plate 5 is arranged at the joint of the rib belt and the other plate belt frame, and finally a layer of clamping plate 6 is laid on the outer sides of the upper cover plate and the lower cover plate.

FIG. 3 is a plate belt frame structure of the simple solid wood pattern of the present invention; the structure and fabrication steps of the related components are described below.

Firstly, according to the structure shown in fig. 3, a rib belt 2 is arranged between an upper cover plate 4 and a lower cover plate 3, a connecting plate 5 is arranged at the contact position with the other plate belt frame, a clamping plate 6 is laid at the outer side in contact with a sand mold, and four plate belt frames are sequentially manufactured. Then, according to the mode of figure 2, four independent plate belt frames 1 are sequentially arranged_-1、1_-2、1_-3、1_-4Placing, then placing on the plate belt frame 1_-1、1_-2、1_-3、1_-4The mutual contact position (namely the rib belt 2 at one end of one plate belt frame and the connecting plate 5 at the other end of the adjacent plate belt frame) is connected and fastened by a screw, after the sand mould is fully hardened, the screw is loosened, and then the plate belt frames 1 are sequentially arranged_-1、1_-2、1_-3、1_-4And taking out from the sand mold.

Simple and easy real appearance wood pattern structure, can be provided with the fixed establishment who prevents to remove in slab band frame hookup department.
