Description

The The present invention relates to a process for producing a two-color cutlery handle, and in particular a manufacturing method, at the projections for injection molding recesses be prepared with certain handle shapes in advance to the Handle two-color manufacture by two processing steps.

It There are several methods of making handles. There is many material variants, as modern people attach great importance to quality of life. Earlier Cutlery became commonplace Made of stainless steel that has been used to make it solid and durable Produce cutlery. In a process in which this material high loads and pressures were used in succession, to form flat cutlery so that it received the desired appearance. This Procedure includes from the beginning to the completed design of the Product many steps. It includes, for example, rough forging, Peel-Forging, Drop Forging, Deburring, Rolling, Pressing of openings, Grinding, heat treatment, Deburring edges and polishing semi-finished products the heat treatment, whereupon a finished article can be presented to the customer. Such a process is very time consuming and requires large and expensive mechanical devices. Furthermore The finished article is made of stainless steel, which from his Color here and because of limited variations monotonous and therefore hardly the claim, cutlery with very different Appearance can be fair.

The Advent of plastic has the situation in the production of Cutlery, usually only metal was used, changed. The application of plastic is commonplace Since this material is readily available, it has been conveniently processed can be and is advantageously easy. Plastic has in many areas replaced the metal, using plastic injection molding the most economical and energy efficient method is.

One conventional Plastic injection molding is e.g. the screw-injection molding, in which a screw is turned to the plastic mass (plastisol) forward to push and put some pressure on it, whereupon then pressure is exerted on the screw spindle, which is the plastisol through a nozzle fills in a cavity of a mold, bringing the entire injection process is completed. Furthermore, there is the conventional plastic injection molding process, such as e.g. the piston injection molding method, in which separated from each other Plastisol and a piston injection molding unit are designed, wherein a plastic melt unit is used to melt plastic and then pour into an injection chamber of a piston, whereupon the piston injection molding unit then pushes the plastic forward and this through a spray nozzle passes and then flows into a casting channel to a cavity of a mold to fill, which in turn completes the whole process. A cutlery handle, by the aforementioned conventional Process has been produced, but is still only monochrome, and is not well received by many customers.

by virtue of strong competition The manufacturers are constantly cutting costs and improving the quality of their products Improve products as well as products of different styles and distribute paints to keep customers interested. Therefore, the present invention provides a new method of preparation a two-colored cutlery handle to the inadequacy the conventional one Avoid procedures.

It is therefore the main object of the present invention, a novel To provide a method for producing a two-colored cutlery handle, wherein one end of the handle with a mating member such as e.g. one Knife, a fork, a spoon or a bottle opener etc. can be connected to a beautiful and durable cutlery handle at a reasonable price.

These The object is achieved by the invention specified in the claims.

• 1. Kunststoffmaterial in einer ersten Farbe wird in eine erste Pressform für Spritzgussausnehmungen mit bestimmten Formen eines Besteckgriffs eingespritzt, um den ersten Verfahrensschritt des Spritzgusses zu erhalten, so dass, wenn der erste Verfahrensschritt durchgeführt wurde, die Ausnehmungen mit bestimmten Formen auf dem Griff ausgebildet werden können.
• 2. Platzieren des im ersten Spritzgussverfahren hergestellten Griffs in eine zwei Pressform und Einspritzen von Kunststoffmaterial in einer zweiten Farbe in die zweite Pressform, um einen zweiten Spritzguss-Verfahrensschritt durchzuführen, wobei die weiteren Ausnehmungen mit der zweiten Farbe gefüllt werden und schließlich zwei Farben auf der Oberfläche des Besteckgriffs zu sehen sind.

In order to achieve the above object, the method of manufacturing a two-color cutlery handle according to the present invention includes the following steps:

• 1. Plastic material in a first color is injected into a first mold for injection moldings with certain shapes of a cutlery handle to obtain the first process step of injection molding, so that when the first process step has been performed, the cavities are formed with certain shapes on the handle can.
• 2. placing the handle produced in the first injection molding process in a two mold and injecting plastic material in a second color in the second mold to perform a second injection molding process step, wherein the further recesses are filled with the second color and finally two colors on the Surface of the cutlery handle can be seen.

• 1. Die vorliegende Erfindung verwendet die Spritzgusstechnik zur Herstellung eines Besteckgriffes, damit dieser zweifarbig ausgebildet werden kann.
• 2. Das Herstellungsverfahren ist einfach und kann die Produktivität steigern, aber dennoch die Herstellungskosten niedrig halten, weshalb es für die Massenfabrikation geeignet ist.

The two-color cutlery handle according to the invention has the following advantages:

• 1. The present invention uses the injection molding technique to produce a cutlery handle to allow it to be bicoloured.
• 2. The manufacturing process is simple and can increase the productivity but still keep the manufacturing cost low, which makes it suitable for mass production.

The The invention will be described below with reference to the accompanying drawings and the description explained in more detail. It demonstrate:

1 a flow chart of the present invention;

2A a perspective view of an embodiment of a semi-finished cutlery handle according to step 1 of the present invention;

2 B a perspective view of an embodiment of a finished cutlery handle according to step 2 of the present invention;

2C a front view of the cutlery handle of the invention 2 B ; and

3A , B, C are front views of the cutlery handle obtained by the steps of the present invention with one end of the cutlery handle connected to various cutlery elements.

According to 1 For example, the manufacturing method of the present invention comprises two steps: according to step 1, plastic material becomes a first color 12 in a first mold for the ejection of recesses of certain shape of a handle 10 and thus perform the first injection molding manufacturing process so that, when performed, the recesses of certain shapes on the handle 10 can be trained; According to step 2, the handle formed in the first injection molding manufacturing process is placed in a second mold and it becomes plastic material of a second color 13 injected into this mold, leaving plastic material of the second color 13 in the recesses with the certain shapes is filled and on the surface of the cutlery handle two colors are visible.

2A shows the appearance of one of the plastic material of the first color 12 manufactured semifinished cutlery handle according to step 1. Due to the fact that the plastic material of the first color 12 in the first mold for injection molding of the recesses 11 is injected in a straight strip, the injection molded cutlery handle 10 on its surface recesses 11 in the form of straight strips and the cutlery handle 10 gets his first color.

2 B shows the appearance of a finished article made of the plastic material of the first color 12 obtained by step 2. The cutlery handle 10 formed by the first injection molding process is placed in the second die, whereupon plastic material of the second color 13 is injected into the second mold to perform the second process step. Due to the fact that the cutlery handle produced by the first injection molding process 10 on its surface recesses 11 has the shape of a straight strip, the plastic material of the second color 13 in the recesses 11 filled so that a striped cutlery handle is created in which the colors 12 . 13 are arranged alternately (see. 2C ).

Likewise, the first mold for the injection molding of the cutlery handle 10 be formed so that it has transversely running, spiral or other combined shaped recesses, whereby many variants of the cutlery handle according to the invention 10 can be produced.

3A , B and C show that the one end of the cutlery handle can be connected to various elements for practical use, such as with a spoon element 20 , a fork element 30 or a knife element 40 for a knife or bottle opener, etc., to integrally form each of these suitable elements with the cutlery handle.
