Abstract

A modular tool box includes a first casing, a partition structure mounted on the first casing and a second casing pivotally mounted on one side of the partition structure. The partition structure is provided to expand the horizontal distance between the first casing and the second casing. Consequently, the receiving space in the tool box is expandable due to the thickness of the partition structure without changing the patterns of the first casing and the second casing.

Description

Modular tool box and manufacturing method thereof

The invention relates to a tool box; in particular to an innovative structure and a manufacturing method of a modular tool box and a manufacturing method thereof.

According to recent years, due to the prosperity of DIY, many people like to use time to repair or assemble furniture themselves. Therefore, there are usually many hand tools that are commonly used, and tools are generally available for easy access and storage to avoid loss. Box to accommodate these hand tools.

In terms of the current plastic molding technology, there is no technical problem in any size of the tool box, and the only consideration for the industry is the production cost, especially the mold cost. In general, smaller tool boxes are usually made by direct injection molding because of limited materials, and for the sake of internal space, and larger ones are usually produced by air blowing. The reason is that if a large tool is produced by direct injection molding, not only the mold cost is relatively high, but also the materials used are relatively large and the overall weight is high. In the process of molding, in order to avoid unevenness of the shot material or after demolding, Shrinkage, its technical requirements are high and new materials must be used. Therefore, under the double cost considerations, most of the large tools are made by blowing air.

However, no matter which method is used to manufacture the tool box, the accommodating space provided in the upper and lower casings is fixed, so the use range is severely limited, and the contents therein cannot be changed, for example, the original supply device. The tool box sold by the sleeve may not be able to place an electric (gas) moving tool; the tool box originally designed to install the electric (gas) moving tool also has no extra space to accommodate different sizes. cylinder. The tools that must be used together must not be placed in a tool box at the same time, which will cause considerable inconvenience to the user.

Therefore, in order to solve this problem, some manufacturers use different molds to manufacture upper and lower shells with different depth specifications to meet different material requirements. However, this is only a way to cure the problem, and to manufacture a pair of different sizes of the casing, it is necessary to prepare a pair of different molds, which will greatly increase the mold cost of the manufacturer. Moreover, the vast majority of toolbox manufacturers are not order-production, but are based on past experience and production. Therefore, shells of different specifications must be separated from stock, so the required inventory space is relatively large, which is bound to Improve the storage costs of the industry.

Therefore, in view of the problems existing in the above-mentioned conventional technologies, how to develop an innovative structure that can be more ideal and practical, and the relevant industry should further consider the goals and directions of breakthrough.

In view of this, the inventor has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the inventor has finally obtained the practical invention.

The main object of the present invention is to provide a tool box and a manufacturing method thereof, and the technical problem to be solved is to think about how to develop a new modular tool box which is more ideal and practical and its manufacturing method. Innovation breakthrough.

The technical feature of the present invention is mainly that the manufacturing method of the modular tool box comprises the following steps: preparing a housing: forming a first housing and a second housing by blow molding, wherein the first housing Each of the body and the second housing is formed with a chamber; and each side of the opening edge of the first housing chamber is respectively provided with a rib; the aluminum extruded frame strip is formed by an aluminum extrusion method, And a frame strip having an appropriate horizontal height, and any side of the frame strip is provided with a continuous groove; a molding spacer structure: the frame strip is cut into an appropriate length according to the circumference of the opening edge of the first casing, and then The contour of the periphery of a casing opening is bent; the first casing is assembled: after the rib and the groove are sleeved with each other, the first casing and the spacing structure are connected by a fixture, and then a The punch impacts the outer side of the spacer structure from the outside to the inside, so that the spacer structure is bent inwardly by the point of impact, that is, the assembly of the first shell and the spacer structure is completed, and the impact dent is formed outside the spacer structure; Set the second shell : The second case is pivoted to the structure on the spacer, and finally hooking structure mounted on the second housing, whereby the first hooking stopper housing, to avoid accidental opening modular kit.

The main effects and advantages of the present invention are that the first housing and the second housing can be mass-produced in a fixed size by the above-described manufacturing method. When the volume of the tool box has different requirements, the application is performed. The structure of the spacer structure is improved, and the aluminum extrusion structure with different levels of height can be used to provide various tool boxes of different volumes under the condition that the mold cost is controlled to the minimum, so as to meet different usage requirements of consumers; Moreover, since the dimensions of the first casing and the second casing are unchanged, it is possible to assemble at any time without prior inventory, thereby reducing the storage cost and improving the productivity.
