Technical Field

[0001] This utility model relates to the field of mold core technology, and in particular to a split upper mold core used in HUD molds. Background Technology

[0002] A head-up display (HUD) is a device that projects navigation and driving information onto the windshield in front of the driver. Injection molding technology plays a crucial role in its manufacturing process. Specifically, HUD manufacturing involves injection compression molding, a technique that injects plastic material into a mold and shapes it using high temperature and pressure. This technology ensures the manufacture of the HUD's precision optical components, enabling it to accurately project information into the driver's field of vision.

[0003] In the prior art, inserts are used on the HUD mold to ensure the injection accuracy of the HUD. However, the inserts are stuck in the upper mold core and are easy to get stuck and cannot be removed. This paper proposes a split upper mold core for use on the HUD mold to solve the problems existing in the prior art. Utility Model Content

[0004] The purpose of this invention is to provide a split upper mold core for use in HUD molds, in order to solve the problem that in the prior art, inserts are used on HUD molds to ensure the injection accuracy of HUDs, but the inserts are stuck in the upper mold core and are easy to get stuck and cannot be removed.

[0005] The technical solution of this utility model is: a split upper mold core applied to a HUD mold, comprising: a plurality of split upper mold core blocks and an insert inserted into at least one of the plurality of upper mold core blocks, each insert fitting into a through groove formed by splicing and enclosing the plurality of upper mold core blocks; and grooves formed on the surfaces of the plurality of upper mold core blocks that contact the inserts.

[0006] Preferably, the groove is serrated and extends horizontally, and the groove is spaced apart to cover the surfaces of the upper mold core blocks that contact the insert.

[0007] Preferably, the plurality of upper mold core blocks are arranged in a centrally symmetrical manner.

[0008] Preferably, the plurality of upper mold core blocks are arranged on the same layer and fixed to the upper template by bolts, and its structure includes a central block arranged in a centrally symmetrical manner, a left first block and a right first block with the same structure, a left second block and a right second block with the same structure, and a left third block and a right third block with the same structure;

[0009] The number of inserts is two, and the two inserts have the same structure, namely the first insert and the second insert.

[0010] Preferably, the first left block, the second left block, and the third left block are sequentially spliced ​​clockwise on the left end face of the center block, and together they enclose a first through groove for the first insert to be inserted.

[0011] The first right block, the second right block, and the third right block are sequentially spliced ​​counterclockwise on the right end face of the center block, and together they enclose the second through slot for the second insert to be inserted.

[0012] Preferably, the first through groove has four groove surfaces, and each groove surface is provided with a groove.

[0013] The second through groove has four groove surfaces, and each groove surface has a groove.

[0014] Preferably, both the first insert and the second insert are fixed to the upper template by bolts.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] (1) In this utility model, a split upper mold core used in HUD mold includes: multiple split upper mold core blocks and inserts inserted into at least one of the multiple upper mold core blocks, each insert fitting into a through groove formed by splicing and enclosing multiple upper mold core blocks; the function of the groove is to reduce the contact area between the insert and the multiple upper mold core blocks, thereby reducing the friction between the insert and the multiple upper mold core blocks, which is conducive to the insert being installed in the multiple upper mold core blocks; the insert is to press the HUD product, and the setting of the insert facilitates the replacement and maintenance of the insert.

[0017] The advantages of the separate upper mold core design in this utility model are as follows: First, if the upper mold core is a single piece, the groove on the upper mold core is on the vertical end face and is concave. This groove is difficult to machine on many machine tools, and the machining time for a one-piece upper mold core is also relatively long. By separating the upper mold core, the side that needs to be machined for the groove is located on the top surface, which can then be machined. Second, the separate upper mold core design allows for machining using CNC, wire cutting, grinding, and other machine tools. More suitable machining methods can be selected, improving the machining accuracy of each upper mold core block, and thus improving the machining accuracy of the entire upper mold core composed of multiple upper mold core blocks. Third, the separate upper mold core block design allows for the simultaneous machining of each upper mold core block, reducing the machining time by 50% compared to a one-piece upper mold core. Fourth, the separate upper mold core design results in better venting of the upper mold core.

[0018] (2) In this utility model, multiple upper mold core blocks are arranged in a centrally symmetrical manner, and the structure includes a centrally symmetrically arranged central block, a left first block and a right first block with the same structure, a left second block and a right second block with the same structure, and a left third block and a right third block with the same structure, which facilitates the processing of the upper mold core blocks.

Grooves 1 are formed on the surfaces of the multiple upper mold core blocks that contact the inserts. The grooves 1 are serrated extending horizontally, and are spaced throughout the surfaces of the multiple upper mold core blocks that contact the inserts. The function of the grooves 1 is to reduce the contact area between the inserts and the multiple upper mold core blocks, thereby reducing the friction between them, which facilitates the insertion of the inserts into the multiple upper mold core blocks. The inserts are used to press the HUD product, and their design facilitates replacement and maintenance. The advantages of the split upper mold core design in this invention are: First, if the upper mold core is a single piece, the grooves 1 on the upper mold core are on the vertical end face and are concave. Grooves 1 are difficult to machine on many machine tools, and machining a single upper mold core takes a relatively long time. Split upper mold cores... First, by placing the side requiring the groove 1 on the top surface, it can be machined. Second, by designing the upper mold core as a separate unit, it can be machined using CNC, wire cutting, grinding, or other machine tools. This allows for the selection of more suitable machining methods, improving the machining accuracy of each upper mold core block, and thus improving the machining accuracy of the entire upper mold core composed of multiple upper mold core blocks. Third, by designing the upper mold core blocks as separate units, each upper mold core block can be machined simultaneously, reducing the machining time by 50% compared to a one-piece upper mold core. Fourth, by designing the upper mold core as a separate unit, the venting effect of the upper mold core is better.

[0028] Multiple upper mold core blocks are arranged symmetrically at the center. These upper mold core blocks are arranged on the same layer and fixed to the upper template with bolts. The structure includes a centrally symmetrically arranged central block 3, two identical left first blocks 4 and 7, two identical left second blocks 5 and 8, and two identical left third blocks 6 and 9. There are two inserts, and the two inserts are identical in structure, namely the first insert 2 and the second insert (not shown in the figure). The left first block 4, left second block 5, and left third block 6 are sequentially assembled clockwise on the left end face of the central block 3, forming a first through slot for the first insert 2 to be inserted. The right first block 7, right second block 8, and right third block 9 are sequentially assembled counterclockwise on the right end face of the central block 3, forming a second through slot for the second insert to be inserted. The first through slot has four grooves, each with a groove 1; the second through slot also has four grooves, each with a groove 1. The first insert 2 and the second insert are both fixed to the upper template by bolts; in this utility model, multiple upper mold core blocks are arranged in a centrally symmetrical manner, and the structure includes a centrally symmetrically arranged central block 3, a left first block 4 and a right first block 7 with the same structure, a left second block 5 and a right second block 8 with the same structure, and a left third block 6 and a right third block 9 with the same structure, which facilitates the processing of the upper mold core blocks.
