Detailed Description

The present application is described in further detail below with reference to the attached drawings.

The embodiment of the application discloses a combined type injection mold, which is used for an insertion piece of an injection molding ear cover. The die comprises an upper die 1 and a lower die 2. The lower main insert 3 is embedded in the lower die 2, and the upper main insert 4 is embedded in the upper die 1. A lower auxiliary insert 5 is embedded in the lower main insert 3, and an upper auxiliary insert 6 is embedded in the upper main insert 4. The lower die 2 is provided with side inserts 7 on two sides of the lower main insert 3 respectively in a sliding manner, and the upper die 1 is provided with cavities 8 on two sides of the upper main insert 4, so that when the upper die 1 and the lower die 2 are assembled, the cavities 8 are wrapped outside the side inserts 7 to prevent the side inserts 7 from being separated from the space between the upper die 1 and the lower die 2. The die is provided with a plurality of different sets of lower auxiliary inserts 5, upper auxiliary inserts 6 and side inserts 7 for replacement.

Specifically, the lower main insert 3 and the lower die 2 are fixed by bolts, and similarly, the upper main insert 4 and the upper die 1 are fixed by bolts. The hole for embedding the auxiliary insert on the lower main insert 3 is arranged in a penetrating way, so that when the lower auxiliary insert 5 is embedded in the lower main insert 3, the side wall of the lower auxiliary insert 5 is abutted against the side wall of the lower die 2. The side wall of the lower auxiliary insert 5 is provided with a sliding block 9 in a protruding way, and the lower main insert 3 is correspondingly provided with a sliding groove 10 for the sliding block 9 to slide. The lower auxiliary insert 5 slides along the sliding groove 10 through the sliding block 9 and is embedded in the lower main insert 3, so that accurate positioning is completed. And the lower auxiliary insert 5 and the lower die 2 are fixed through bolts, so that the stability in the processes of die assembly and injection molding is ensured.

The side insert 7 is provided with a limiting strip 11 protruding along both sides of the length direction, the lower die 2 is correspondingly provided with a limiting groove 12 for the limiting strip 11 to slide, and the length direction of the limiting strip 11 is the same as the width direction of the side insert 7. The side insert 7 is connected with a plug-in post 16, and after the upper die 1 and the lower die 2 are closed, the end part of the plug-in post 16 extends into the die cavity and is used for forming a side hole of a product.

Positioning blocks 13 are protruded at four corners of the upper insert; the peripheral side corners of the lower insert are correspondingly provided with positioning grooves 14 for the positioning blocks 13 to be clamped in, so that accurate matching is ensured.

The lower main insert 3 is embedded with two lower auxiliary inserts 5, and correspondingly, the upper main insert 4 is embedded with two upper auxiliary inserts 6. When the upper die 1 and the lower die 2 are closed, two die cavities are formed, and two corresponding inserting columns 16 on the side insert 7 are respectively inserted into the two die cavities. An injection molding channel 15 is arranged between the upper main insert 4 and the lower main insert 3, two ends of the injection molding channel 15 are respectively communicated with the two mold cavities, and the glue inlet hole is positioned in the center of the injection molding channel 15.

The die can be fitted with a plurality of different sets of upper and lower

minor inserts

6, 5, and different side inserts 7. When different products need to be injection molded, the lower auxiliary insert 5 and the upper auxiliary insert 6 are replaced simultaneously, and the injection molding machine can be used for injection molding of another product with the same overall appearance. Similarly, the side insert 7 is replaced, and hole sites with different shapes can be formed on the product due to the different shapes of the inserting columns 16 on the different side inserts 7. Through the combined die, the inner insert is convenient to replace, different products are formed, and the production cost is reduced.

The above are preferred embodiments of the present application, and the scope of protection of the present application is not limited thereto, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
