Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

As shown in fig. 1, a multi-layer insert product 11 includes a multi-layer insert 12 and an injection molded part 13 injection molded around a portion of the outer periphery of the insert 12 (the insert 12 having an exposed portion).

Referring to fig. 2, the multiple layer inserts 12 are stacked and positioned prior to injection molding to ensure proper placement of the inserts 12.

As shown in fig. 3, which is an enlarged schematic view of a position a in fig. 2, a positioning hole 2 is formed at a corresponding position on the multi-layer insert 12, and a positioning rod 1 is inserted into the positioning hole 2 for positioning.

As shown in fig. 4, the positioning rod 1 includes a rod portion 3, and a positioning portion 4 and a stopper portion 6 provided at both ends of the rod portion 3, respectively. The stop part 6 is a protrusion extending transversely and embedded in a male die and/or a female die where the positioning rod 1 is located, and is used for preventing the positioning rod 1 from being separated. The stopper portion 6 is provided at one end of the lever portion 3 for manufacturing convenience, but the position of the stopper portion 6 on the lever portion 3 is not particularly limited, and in other ways, the stopper portion 6 may be provided at other portions of the lever portion 3 than the end portion.

Wherein, the positioning part 4 comprises a plurality of steps 5, and each step 5 is approximately cylindrical and matched with the positioning hole 2. The outer diameter of the step 5 decreases in the axial direction. Referring to fig. 3, the diameters of the positioning holes 2 of the inserts 12 are also reduced in sequence, and specifically, the diameters of the positioning holes 2 of the inserts 12 in multiple layers are reduced in sequence in the insertion direction of the positioning rod 1. The positioning portion 4 (step 5) is matched with the positioning hole 2, as shown in fig. 4, the outer side surface 8 on the step 5 is in clearance fit with the positioning hole 2 (see fig. 3), and the step surface 7 on the step 5 abuts against the insert 12 so as to abut against the insert 12 in the inserting direction. The distance between adjacent layer inserts 12 can be controlled by the height of the step 5.

The positioning holes 2 are distributed at multiple points in the single insert 12, positioning points are added, and therefore the positioning effect is improved.

In this example, locating rods 1 are arranged in the male die and the female die, and the directions of inserting the locating rods 1 in the male die and the locating rods 1 in the female die into the inserts 12 are opposite, that is, the locating rods 1 are inserted into the inserts 12 in two directions, so that on one hand, locating points are increased to improve locating effect, and on the other hand, the inserts 12 can be tightly abutted to each other in two directions to improve locating effect.

In this example, the positioning rod 1 is provided in both the male mold and the female mold, but the positioning rod 1 may be provided only in the male mold or only in the female mold.

In this example, as shown in fig. 5, a cavity 15 is provided in a male mold 14, a plurality of layers of inserts 12 are placed in the cavity 15, and positioning rods 1 (not shown) in the male mold 14 are inserted into positioning holes of the inserts 12 to accurately position the inserts 12. When the mold is closed, the positioning rod in the master mold (not shown in the figure) is further inserted into the insert 12 to further position the insert before injection molding, and then injection molding is performed, thus improving the product quality.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
