Description

Technical Field

[0001] This utility model relates to the technical field of positioning metal parts, and in particular to a positioning component for positioning metal parts. Background Technology

[0002] The structure of metal part 1 produced in a certain workshop is as follows: Figures 1-2 As shown, it includes a part body 2, with two protruding plates I3 fixed on the rear end face of the part body 2, forming a gap between the two protruding plates I3. Protruding plates II4 are fixed on both the left and right end faces of the part body 2, and two through holes 5 are opened inside the part body 2. The process requires that a layer of plastic be injection molded at a designated position on the top surface of the metal part 1 to obtain an embedded product.

[0003] Before injection molding, a positioning component is used to position the metal part 1 within the cavity 6, ensuring that the metal part 1 is directly below the injection mold, thereby ensuring that the plastic layer injected onto the top surface of the metal part 1 is at the designated position. The positioning component includes two positioning pins 8 fixed to the bottom surface of the inner cavity 7 of the cavity 6. The distance between the two positioning pins 8 is equal to the distance between the two through holes 5 within the metal part 1, and the diameter of the positioning pins 8 is equal to the diameter of the through holes 5.

[0004] The method by which the worker positions the metal part 1 using this positioning component is as follows: The worker takes out a metal part 1, places the two through holes 5 of the metal part 1 onto the two positioning posts 8 respectively, and supports the bottom surface of the metal part 1 on the bottom surface of the inner cavity 7 of the die 6, thereby achieving the positioning of the metal part 1. At this time, the two positioning posts 8 restrict the displacement of the metal part 1, and the metal part 1 is exactly below the injection mold. After the metal part 1 is positioned, the injection mold is made to fit into the inner cavity of the die 6, and then a layer of plastic is injected into the designated position on the top surface of the metal part 1 through the injection mold, thus obtaining the embedded product.

[0005] However, although this positioning component can achieve the positioning of metal part 1, it still has the following technical defects in actual use:

[0006] The inner walls of the through holes 5 of the metal part 1 are covered with a large number of burrs. This causes the metal part 1 to be tilted when the worker places the two through holes 5 of the metal part 1 onto the two positioning posts 8 respectively. In other words, the bottom surface of the metal part 1 is not supported on the bottom surface of the inner cavity of the mold cavity 6. This causes the injection mold to hit the tilted metal part 1 during its downward movement, resulting in damage to the metal part 1 and increasing the production cost of the embedded product.

[0007] Furthermore, because the metal part 1 is in an inclined state and is not precisely positioned directly below the injection mold, the injection mold does not inject the metal part 1 into the designated position, thereby reducing the production quality of the embedded product.

[0008] Therefore, there is an urgent need for a positioning component that can accurately position metal parts and improve the production quality of embedded products. Utility Model Content

[0009] The purpose of this invention is to overcome the shortcomings of the prior art and provide a positioning component for positioning metal parts that can accurately position metal parts and improve the production quality of embedded products.

[0010] The purpose of this utility model is achieved through the following technical solution: a positioning component for positioning metal parts, which includes a clamping component A and a clamping component B respectively disposed on the left and right side walls of the die cavity. The clamping component A includes a stepped hole opened on the inner side wall of the inner cavity of the die cavity and a blind groove opened on the inner side wall of the inner cavity. A magnetic block is embedded in the blind groove, and a movable rod slides through the small hole of the stepped hole.

[0011] The left end of the movable rod extends outside the cavity of the die, and the right end of the movable rod extends into the cavity of the die. A movable plate is fixed on the extended end. The left end face of the movable plate is attracted to the magnetic block. A spring in a compressed state is fixed on the left end face of the movable plate. The spring is sleeved on the movable rod. The left end of the spring is fixed on the stepped surface of the stepped hole. A rod is fixed on the right end face of the movable plate. The rod extends to the right and a round block is welded on the bottom surface of the extended end.

[0012] A fixed seat is fixed on the bottom wall of the inner cavity of the die, and a vertically arranged positioning block is fixed on the front end face of the fixed seat. The horizontal width of the positioning block is equal to the width between the two protrusions I of the metal part.

[0013] The clamping components A and B are arranged symmetrically about the positioning block.

[0014] The magnetic block is interference-fitted with the blind slot, and the magnetic block is flush with the inner wall of the cavity of the die.

[0015] Connecting seats are fixed on both the left and right outer end faces of the die.

[0016] The movable rod and the rod are on the same horizontal straight line.

[0017] This invention has the following advantages: it can accurately position metal parts and improve the production quality of embedded products. Attached Figure Description

[0035] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0036] like Figures 7-10 As shown, a positioning assembly for positioning metal parts includes a clamping assembly A9 and a clamping assembly B10 respectively disposed on the left and right sidewalls of a die 6. The clamping assemblies A9 and B10 are symmetrically arranged about a positioning block 19. The clamping assembly A9 includes a stepped hole 11 and a blind groove on the inner sidewall of the cavity 7 of the die 6. A magnetic block 12 is embedded in the blind groove, and a movable rod 13 slides through the small hole of the stepped hole 11. The magnetic block 12 is interference-fitted with the blind groove and is flush with the inner sidewall of the cavity 7 of the die 6. Connecting seats are fixed on the left and right outer end faces of the die 6 for supporting the worktable.

[0037] The left end of the movable rod 13 extends outside the cavity 6, and the right end of the movable rod 13 extends into the cavity of the cavity 6. A movable plate 14 is fixed on the extended end. The left end face of the movable plate 14 is attracted to the magnetic block 12. A spring 15 in a compressed state is fixed on the left end face of the movable plate 14. The spring 15 is sleeved on the movable rod 13. The left end of the spring 15 is fixed on the stepped surface of the stepped hole 11. A rod 16 is fixed on the right end face of the movable plate 14. The rod 16 extends to the right and a round block 17 is welded to the bottom surface of the extended end. The movable rod 13 and the rod 16 are on the same horizontal straight line.

[0038] A fixing seat 18 is fixed on the bottom wall of the inner cavity of the die 6. A vertically arranged positioning block 19 is fixed on the front end face of the fixing seat 18. The horizontal width of the positioning block 19 is equal to the width between the two protrusions I3 of the metal part 1.

[0039] The method of positioning the metal part 1 within the die 6 according to this utility model is as follows:

[0040] S1, the worker takes out a... Figures 1-2 The metal part 1 shown is secured from top to bottom to the positioning block 19 by the gap formed by the two protruding plates I3 of the metal part 1. Figures 11-12 As shown, the bottom surface of the metal part 1 is supported on the bottom wall of the inner cavity 7 of the die 6. At this time, the angle formed by the left convex plate II4 of the metal part 1 and the left end face of the metal part 1 is exactly opposite to the circular block 17 of the clamping assembly A9. At the same time, the angle formed by the right convex plate II4 of the metal part 1 and the right end face of the metal part 1 is exactly opposite to the circular block 17 of the clamping assembly B10.

[0041] S2. The worker presses the movable rod 13 of the clamping assembly A9 to the right. The movable rod 13 drives the moving plate 14 to move to the right. After the moving plate 14 separates from the magnetic block 12, under the elastic restoring force of the spring 15, the spring 15 pushes the moving plate 14 to move to the right. The moving plate 14 drives the rod 16 and the round block 17 to move to the right simultaneously. The round block 17 of the clamping assembly A9 is embedded in the angle formed by the left convex plate II4 of the metal part 1 and the left end face of the metal part 1. Figures 13-14 As shown;

[0042] S3. The worker presses the movable rod 13 of the clamping assembly B10 to the left by hand. Under the elastic restoring force of the spring 15, the round block 17 of the clamping assembly B10 is embedded in the angle formed by the right side protrusion II4 of the metal part 1 and the right end face of the metal part 1, as shown. Figures 13-14 This achieves the positioning of metal part 1. At this time, metal part 1 is just confined between the circular block 17 and the positioning block 19, and metal part 1 is just directly below the injection mold.

[0043] S4. After the metal part 1 is positioned, the injection mold is made to fit into the inner cavity of the cavity mold 6. Then, a plastic layer is injected into the designated position on the top surface of the metal part 1 through the injection mold to obtain the embedded product.

[0044] In steps S2-S4, the circular block 17 of the clamping assembly A9 is embedded in the angle formed by the left convex plate II4 of the metal part 1 and the left end face of the metal part 1. Simultaneously, the circular block 17 of the clamping assembly B10 is embedded in the angle formed by the right convex plate II4 of the metal part 1 and the right end face of the metal part 1, thereby achieving the positioning of the metal part 1. Therefore, it can be seen that this positioning assembly, compared to... Figures 3-6 The positioning component shown replaces the positioning using the through hole 5 and positioning post 8 of the metal part 1. Instead, it uses the outer contour of the metal part 1 to position the metal part 1, thereby ensuring that the metal part 1 is always placed in a horizontal position. This avoids the injection mold from hitting the metal part 1 during downward movement, thus effectively protecting the metal part 1.

[0045] Furthermore, since the metal part 1 is not placed at an angle, it ensures that the injection mold can accurately inject the metal part 1 into the designated position, thereby greatly improving the production quality of the embedded product.

[0046] S5. Removal of the embedded part: The worker pulls the movable rod 13 of the clamping assembly A9 and the clamping assembly B10 outward. The movable rod 13 drives the moving plate 14 to move outward. The moving plate 14 drives the rod 16 and the round block 17 to move outward synchronously. The round block 17 separates from the metal part 1. When the moving plate 14 comes into contact with the magnetic block 12, the moving plate 14 is once again attracted and fixed on the magnetic block 12. Then the worker removes the embedded product.

[0047] S6. The worker repeats steps S1 to S5 multiple times to inject a plastic layer onto the top surface of multiple metal parts 1, thereby obtaining multiple embedded products.

[0048] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
