Description

Mouse roller injection molding mold

Technical Field

The utility model relates to mouse injection moulding technical field, concretely relates to mouse gyro wheel injection moulding mould.

Background

The mouse is known and common by the public as an important appliance in daily office work, and the mouse shell is an important component of the mouse. In the production process of the mouse, a layer of paint is required to be sprayed on the surface of a mouse button, so that the attractiveness and the hand feeling of the mouse are improved. The shell of the mouse comprises an upper shell, a lower shell and a middle shell arranged in the middle. The mouse wheel is generally made of plastic, and when the mouse wheel is manufactured, the mouse wheel is generally molded in a mold in advance to be molded.

At present, a hexagonal column structure of a mouse roller belongs to a component with the highest precision requirement in a mouse product, and the common design tolerance is +/-0.01 mm. In most designs, an integral interchangeable insert is made. However, the insert has multiple structures, multiple processing technologies and long processing time, and is not beneficial to repair and maintenance of the mold.

Disclosure of Invention

The utility model aims at providing a mouse gyro wheel injection moulding mould, this mould is through changing the mold insert structure, and the whole line of cancellation cuts the mold insert to reach the purpose of practicing thrift process time and processing cost.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a mouse gyro wheel injection moulding mould which the key lies in: including first mould benevolence and second mould benevolence be formed with a plurality of molding cavities that are used for mouse gyro wheel shaping between first mould benevolence and the second mould benevolence wear to be equipped with a plurality of mould benevolence inserts in the second mould benevolence, this mould benevolence insert is located under the molding cavity still wear to be equipped with a plurality of inserts in the second mould benevolence and go into son, every mould benevolence insert is gone into son and the cooperation of second mould benevolence joint through an insert respectively set up the hexagonal hole with the hexagonal post looks adaptation of mouse gyro wheel on the insert is gone into son.

Furthermore, the arrangement direction of the mold core insert is perpendicular to the arrangement direction of the insert.

Furthermore, the lower end of the mold insert is provided with a limiting part which is clamped in a limiting step arranged on the second mold insert.

Furthermore, an injection molding runner is formed in the center of the mold core insert and communicated with the hexagonal hole and the molding cavity.

Furthermore, the hexagonal hole is composed of a conical section and a prismatic section, the conical section is positioned above the prismatic section, and the small end of the conical section is connected with the upper end of the prismatic section.

Furthermore, the insert is strip-shaped, and the length of the insert is consistent with the width of the second mold core.

The utility model discloses a show the effect and be:

this application is through canceling whole line cutting mold insert, goes into the fixed of son realization mould benevolence mold insert through the mold insert, compares in the whole mould benevolence among the prior art and adopts the mode of direct line cutting as exchanging the mold insert, and the processing of not only being convenient for more has reduced important part manufacturing process, has shortened process time, and it is also more convenient when changing mould benevolence mold insert in the later stage moreover, will practice thrift mould later maintenance cost.

Detailed Description

The following provides a more detailed description of the embodiments and the operation of the present invention with reference to the accompanying drawings.

As shown in fig. 1-6, an injection molding mold for a mouse roller comprises a first mold core 1, a second mold core 2 and other components (not shown), wherein a plurality of molding cavities 3 for molding a mouse roller S are formed between the first mold core 1 and the second mold core 2, a plurality of mold core inserts 4 are arranged in the second mold core 2 in a penetrating manner, the mold core inserts 4 are positioned under the molding cavities 3, a plurality of insert inserts 5 are arranged in the second mold core 2 in a penetrating manner, each mold core 4 is respectively matched with the second mold core 2 in a clamping manner through one insert 5, a hexagonal hole 6 matched with a hexagonal column of the mouse roller S is formed in the insert 5, an injection flow channel is formed in the center of the mold core 4, and the injection flow channel is communicated with the hexagonal hole 6 and the molding cavities 3.

In this embodiment, the installation direction of the mold core insert 4 is perpendicular to the installation direction of the insert 5, a limiting portion 41 is formed at the lower end of the mold core insert 4, and the limiting portion 41 is clamped in a limiting step formed on the second mold core 2.

As shown in fig. 3, 6 and 7, the hexagonal hole 6 is composed of a conical section 61 and a prismatic section 62, the conical section 61 is located above the prismatic section 62, and the small end of the conical section 61 is connected with the upper end of the prismatic section 62, so that the hexagonal hole 6 is more fit with the hexagonal column of the mouse wheel S through the above structural design, thereby effectively ensuring the accuracy of the hexagonal column.

Furthermore, the insert 5 is strip-shaped, and the length of the insert 5 is consistent with the width of the second mold core 2, so that the production is facilitated, and the insert 5 is convenient to disassemble/assemble.

Among the prior art, mould benevolence adopts the mode of whole direct line cutting as exchanging the mold insert, and this application is then through canceling whole line cutting mold insert, goes into son 5 through the mold insert and realizes the fixed of mould benevolence mold insert 4, and mould benevolence mold insert 4, mold insert go into son 5 and be convenient for processing more not only, have reduced important part processing technology, have shortened process time, and it is also more convenient when changing mould benevolence mold insert 4 in the later stage moreover, will practice thrift mould later maintenance cost.

The technical scheme provided by the utility model is introduced in detail above. The principles and embodiments of the present invention have been explained herein using specific examples, and the above descriptions of the embodiments are only used to help understand the method and its core ideas of the present invention.
