Description
Technical Field
[0001] The utility model relates to the technical field of injection molds, and particularly relates to an injection mold for an injection molded part with an embedded metal sheet. Background Art
[0002] A composite injection molded part refers to a part in which a metal part or other parts of other materials are embedded in an injection molded part. For the production of composite injection molded parts, generally, the embedded parts are first placed in a mold and then injection molded. The existing molds can only produce single products. Even when multiple molds are used for simultaneous production, the embedded parts need to be placed in the injection mold sequentially, resulting in low efficiency. Moreover, a relatively large part of some embedded parts exposed outside the injection molded part cannot be effectively positioned, resulting in poor accuracy of the injection molded products and failing to meet the requirements. Therefore, the utility model proposes an injection mold for an injection molded part with an embedded metal sheet. Content of the Utility Model

[0018] Embodiment:
[0019] For the production of an injection molded part with an embedded metal sheet as Figure 1 shown, the present utility model proposes an injection mold for an injection molded part with an embedded metal sheet as Figures 2 to 7 shown, which includes two mounting blocks 1 arranged up and down. The two mounting blocks 1 are driven by cylinders to approach and separate from each other. On a pair of opposite surfaces of the two mounting blocks 1, mounting grooves 2 are provided along their length directions. A plurality of mold bodies are arranged in the mounting grooves 2. The mold bodies include an upper mold 3 and a lower mold 4 respectively arranged in the two mounting grooves 2. A gate 5 is provided on the lower mold 4. An insert fixture is arranged between the two mounting blocks 1. The insert fixture includes a lower pressing plate 6 and an upper pressing plate 7. An insert positioning pin 8 is fixed on the upper end surface of the lower pressing plate 6. A limiting groove 9 is provided on the upper end surface of the lower pressing plate 6 along its length direction. A through hole for the positioning pin to pass through is provided on the upper pressing plate 7. A pressing plate limiting groove is provided on the mounting block 1. A pressing plate positioning pin 10 is provided on the lower mounting block 1. Pressing plate positioning holes are provided on both the lower pressing plate 6 and the upper pressing plate 7. An insert limiting mechanism is provided on one side of the mold body.
[0020] On a pair of opposite surfaces of the upper mold 3 and the lower mold 4, forming grooves 11 are provided. The two forming grooves 11 form a cavity. A gate 5 communicating with the forming groove 11 is provided on the front surface of the lower mold 4. A fixing block 12 is arranged in the mounting groove 2. A glue injection nozzle 13 facing the gate 5 is provided on the fixing block 12. The glue injection nozzle 13 is connected to an injection molding machine through a pipeline. An avoidance opening 14 for inserting a metal part is provided on one side of the forming groove 11.
[0021] The insert limiting mechanism includes a positioning block 15 fixed on the left side surface of the lower mold 4. The top of the positioning block blocks the avoidance opening 14. A profiling positioning groove 16 is provided at the top end of the positioning block 15. A notch 17 communicating with the avoidance opening 14 is provided on the right side of the profiling positioning groove 16. A lower limiting block 18 is fixed on the left side of the positioning block 15. A limiting convex block 19 is provided on the upper end surface of the lower limiting block 18. An upper limiting block 20 is arranged above the lower limiting block 18. The upper limiting block 20 is fixed on the upper mounting block 1. A pressing block 21 extending into the notch 17 is provided on the lower end surface of the upper limiting block 20.
[0022] The mold bodies are symmetrically arranged in two rows with respect to the lower pressing plate 6.
[0023] The working process of this application is as follows: Drive the two mounting blocks 1 apart through a cylinder, take out the lower pressing plate 6 and the upper pressing plate 7, separate the upper pressing plate 7 from the lower pressing plate 6, fix the insert to be injection-molded to the lower pressing plate 6. The insert 22 is a metal sheet, including a metal strip portion 23, a connecting portion 24, and an injection-molded portion 25. The connecting portion 24 is hook-shaped. A limiting plate 26 and an insert positioning hole 27 that are bent downward are provided on the metal strip portion 23. Fix the insert to the lower pressing plate 6. The insert positioning pin 8 passes through the insert positioning hole 27, and the limiting plate 26 extends into the limiting groove 9, so that the metal strip portion is fixed. Press the upper pressing plate 7 on the upper end surface of the metal strip portion 23. Install the assembled insert jig on the lower mounting block 1. The left end of the injection-molded portion 25 is snapped into the profiling positioning groove 16, and the right end of the injection-molded portion 25 extends into the forming groove 11 through the notch 17. The limiting convex block 19 abuts against the left end of the injection-molded portion 25, thereby preventing the injection-molded portion 25 from moving to the left. Drive the upper mounting block 1 to descend through a cylinder, so that the upper mold 3 and the lower mold 4 are combined. The upper limiting block 20 presses on the lower limiting block 18. The pressing block 21 extends into the notch 17 and presses on the upper end surface of the injection-molded portion 25, so that the injection-molded portion 25 is fixed. Inject plastic into the cavity through the gate 5 to form an injection molding port. Separate the two mounting blocks 1 through a cylinder, take out the insert jig, and then the product can be taken out. Multiple sets of insert jigs can be configured for alternate feeding, thus greatly improving the working efficiency.
[0024] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the creative concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
