Description

Technical Field

[0001] This invention relates to a novel precision metal parts injection molding processing device and method that facilitates demolding, belonging to the field of metal parts injection molding processing technology. Background Technology

[0002] Metal parts refer to a collective term for metal blocks, rods, tubes, etc., of various specifications and shapes manufactured from metallic materials. Materials for metal parts include iron and steel, and non-ferrous metals (or non-ferrous metals). Iron and steel: Iron alloys with a carbon content of 2%–4.3% are cast iron, while iron alloys with a carbon content generally between 0.03% and 2% are steel. Various appropriate amounts of alloying elements are intentionally added to Fe-C alloys to improve the strength, hardness, wear resistance, and corrosion resistance of steel. Commonly used alloying elements include Si, Mn, Cr, Ni, Mo, W, V, Ti, Nb, and B, forming a wide variety of alloy cast irons or alloy steels.

[0003] Existing injection molding equipment can only demold individual molds, which prevents the overall production efficiency of the factory from being effectively improved. Therefore, this invention provides a novel precision metal parts injection molding equipment that facilitates demolding to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems and shortcomings of the existing technology by designing a novel precision metal parts injection molding processing device that can improve the efficiency of precision metal parts injection molding and facilitate demolding.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows:

[0006] A novel precision metal parts injection molding processing device for easy demolding includes a processing table. The inner wall of the processing table is equipped with a conveying mechanism, a demolding mechanism, and a mounting plate. Multiple outer molds are fixedly connected to the top of the mounting plate. Multiple injection guns and multiple air guns are fixedly connected to the top of the processing table. Each injection gun corresponds to one outer mold. The multiple outer molds are demolded by the demolding mechanism.

[0007] Preferably, the conveying mechanism includes a bearing frame fixed on the inner wall of the bottom of the processing table, two bearing frames are fixedly connected to a drive shaft, the outer ring of the drive shaft is fixedly fitted with a conveyor roller, and the two conveyor rollers are connected by a conveyor belt.

[0008] Preferably, a servo motor is fixedly connected to the inner wall of the processing table by bolts, and the output end of the servo motor is fixedly connected to one of the transmission shafts by a coupling, while the outer ring of the other transmission shaft is fixedly fitted with a drive wheel.

[0009] Preferably, the demolding mechanism includes a drive shaft and a hollow plate. The drive shaft is rotatably connected to the inner wall of the processing table. A driven wheel is fixedly sleeved on the outer ring of the drive shaft. The driven wheel is connected to the driving wheel via a belt. The two sides of the hollow plate are slidably connected to the processing table and the mounting plate, respectively. The hollow plate is fixedly connected to multiple inner molds via connecting rods. The inner molds are adapted to the outer molds.

[0010] Preferably, one end of the drive shaft is fixedly connected to a protrusion via a rotating shaft, and the protrusion is movably fitted inside the inner ring of the hollow plate.

[0011] Preferably, the inner mold located on the far left is fixedly connected to a baffle, which is slidably connected to the mounting plate via a slider.

[0012] Preferably, both the outer mold and the inner mold have openings at their tops, and the mounting plate has a discharge port located on one side of the outer mold.

[0013] The beneficial effects achieved by this invention are as follows:

[0014] The demolding mechanism can separate parts from multiple outer molds at once, and the removed parts can be directly transported to the conveying mechanism, so that the parts can be directly transferred away through the conveying mechanism, thereby effectively improving the processing efficiency of precision metal parts injection molding.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention. Example

[0020] like Figure 1 and Figure 2 As shown, the present invention proposes a novel precision metal parts injection molding processing device that facilitates demolding. It includes a processing table 1, with a conveying mechanism, a demolding mechanism, and a mounting plate 8 installed on the inner wall of the processing table 1. Multiple outer molds 16 are fixedly connected to the top of the mounting plate 8. Multiple injection guns 14 and multiple air guns 15 are fixedly connected to the top of the processing table 1. Each injection gun 14 corresponds to one outer mold 16. The multiple outer molds 16 are demolded through the demolding mechanism. The conveying mechanism includes a bearing bracket 2 fixed to the inner wall of the bottom of the processing table 1. Two bearing brackets 2 are fixedly connected to a drive shaft 3. A conveying roller 4 is fixedly sleeved on the outer ring of the drive shaft 3. The two conveying rollers 4 are connected by a conveyor belt 5. A servo motor 6 is fixedly connected to the inner wall of the processing table 1 by bolts. The output end of the servo motor 6 is fixedly connected to one of the drive shafts 3 via a coupling. A drive wheel 7 is fixedly sleeved on the outer ring of the other drive shaft 3. Openings are provided on the tops of both the outer molds 16 and the inner molds 19. A discharge port is provided on the mounting plate 8, located on one side of the outer mold 16.

[0021] In this embodiment, the material is injected into the interior of the outer mold 16 by the air gun 15, thereby completing the injection molding. At the same time, the servo motor 6 drives the transmission shaft 3 connected to it to rotate through the connecting shaft. The rotation of the transmission shaft 3 drives another transmission shaft 3 and the transmission roller 4 to rotate on the bearing frame 2 through the conveyor roller 4 and the conveyor belt 5, so that the conveyor belt 5 can transport the object. Example

[0022] like Figure 1-3 As shown, the present invention proposes a novel precision metal parts injection molding processing device that facilitates demolding. Compared with Embodiment 1, the demolding mechanism of this embodiment includes a drive shaft 9 and a hollow plate 17. The drive shaft 9 is rotatably connected to the inner wall of the processing table 1. A driven wheel 10 is fixedly sleeved on the outer ring of the drive shaft 9. The driven wheel 10 is connected to the drive wheel 7 through a belt 11. The two sides of the hollow plate 17 are slidably connected to the processing table 1 and the mounting plate 8, respectively. A plurality of inner molds 19 are fixedly connected to the hollow plate 17 through a connecting rod 18. The inner molds 19 are adapted to the outer molds 16. One end of the drive shaft 9 is fixedly connected to a protrusion 13 through a rotating shaft 12. The protrusion 13 is movably sleeved in the inner ring of the hollow plate 17. The leftmost inner mold 19 is fixedly connected to a baffle 20. The baffle 20 is slidably connected to the mounting plate 8 through a slider 21. The top of both the outer mold 16 and the inner mold 19 has an opening. The mounting plate 8 has a discharge port located on one side of the outer mold 16.

[0023] In this embodiment, the initial position of the inner mold 19 is located inside the outer mold 16, and the top openings of the outer mold 16 and the inner mold 19 are completely overlapped, so that the injection gun 14 can inject material into the interior of the outer mold 16 and the inner mold 19 to form the part. Then, the reciprocating motion of the perforated plate 17 will cause the inner mold 19 to separate from the outer mold 16. When the opening of the inner mold 19 moves to the bottom of the air gun 15, the air pressure sprayed by the air gun 15 will push the part to separate from the inner mold 19 and finally fall onto the conveyor belt 5 through the discharge port of the mounting plate 8.

[0024] Working principle: First, the servo motor 6 is started. The servo motor 6 drives the connected transmission shaft 3 to rotate via the connecting shaft. The rotation of the transmission shaft 3 drives another transmission shaft 3 and transmission roller 4 to rotate on the bearing bracket 2 via the conveyor roller 4 and conveyor belt 5. This causes the connected drive wheel 7 to drive the drive shaft 9 to rotate via the belt 11 and driven wheel 10. The rotation of the drive shaft 9 drives the hollow plate 17 to reciprocate on the mounting plate 8 via the rotating shaft 12 and protrusion 13. Since the initial position of the inner mold 19 is located inside the outer mold 16, and the outer mold 16... The top opening of the inner mold 19 is completely aligned with the outer mold 16. Therefore, after the material is injected into the inner mold 16 and the outer mold 19 through the injection gun 14, the reciprocating motion of the cutout plate 17 will cause the inner mold 19 to separate from the outer mold 16. When the opening of the inner mold 19 moves to the bottom of the air gun 15, the air pressure sprayed by the air gun 15 will push the part to separate from the inner mold 19. Finally, it will fall onto the conveyor belt 5 through the discharge port of the mounting plate 8. After that, the cutout plate 17 will drive the inner mold 19 back into the outer mold 16, and the injection gun 14 will complete the injection again. This process is repeated.

[0025] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
