Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to an in-mold automatic assembly mechanism and a stamping die. Background Technology

[0002] In traditional stamping die production, stamping and assembly are usually two separate processes. First, a stamping die is used to stamp the part to obtain the required stamped part; then the stamped part is transported to the assembly station, where it is assembled with other components by manual labor or other assembly equipment.

[0003] This traditional production method has many drawbacks. On the one hand, separating stamping and assembly increases the complexity and cycle time of the production process, reducing production efficiency. On the other hand, during parts transfer, collisions and wear can easily damage parts, affecting product quality and increasing production costs. Furthermore, inaccurate positioning is common during assembly, leading to products that do not meet quality requirements, resulting in more defective products and further increasing production costs and wasting resources. Therefore, developing a mechanism that enables automated in-mold assembly is of significant practical importance. Utility Model Content

[0004] The purpose of this invention is to address the numerous drawbacks of traditional production methods in the existing technology. On the one hand, separating stamping and assembly increases the complexity and cycle time of the production process, reducing production efficiency. On the other hand, during the transfer of parts, damage due to collisions and wear can easily occur, affecting product quality and increasing production costs. Furthermore, inaccurate positioning is also common during assembly, easily leading to assembled products that do not meet quality requirements, resulting in a large number of defective products, further increasing production costs and wasting resources. Therefore, this invention proposes an in-mold automatic assembly mechanism and stamping die.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An in-mold automatic assembly mechanism includes a base plate, on which a mounting plate is fixedly mounted, and on which a pressure plate is fixedly mounted;

[0007] The pressure plate, mounting plate, and base plate are all provided with through holes for the die head to pass through. The bottom of the pressure plate is provided with an elongated hole for placing the stamped parts. The stamped parts are provided with multiple mounting holes.

[0008] A sliding box is slidably disposed within a rectangular hole opened at the bottom of the substrate;

[0009] A receiving box is movably disposed within a receiving cavity opened at the top of the sliding box for receiving an assembly, on which a round rod is fixedly mounted;

[0010] The stamped parts are placed in the elongated hole, and the finished product formed by the stamping of the die head is pushed above the round rod and interference-fitted with it to complete the in-mold assembly; the sliding box can be pulled out from the rectangular hole to expose the receiving box, which facilitates the loading and unloading of products.

[0011] In one possible design, the top of the mounting plate has a mounting groove, in which a pad is detachably mounted by screws. Two symmetrically arranged limiting rods are fixedly mounted on one side of the top of the pad for initial positioning of the stamped parts.

[0012] In one possible design, the holes on the stamped finished product can be engaged with the limiting rod to achieve precise positioning of the stamped parts.

[0013] In one possible design, a handle is fixedly mounted on one end of the sliding box.

[0014] In one possible design, rollers are installed on both sides of the sliding box, and long sliding grooves adapted to the rollers are formed on the inner walls of both sides of the rectangular hole. The rollers are slidably connected inside the long sliding grooves to reduce sliding resistance.

[0015] In one possible design, the sliding box can be easily pulled out via the handle, and the rollers roll within the long groove.

[0016] A stamping die, including the above-mentioned in-die automatic assembly mechanism, further includes:

[0017] The top plate is fixedly installed above the base plate by multiple support rods;

[0018] A hydraulic rod is fixedly installed on the top of the top plate;

[0019] The mold head is connected to the lower end of the piston rod of the hydraulic rod;

[0020] The hydraulic rod drives the mold head downward to stamp the stamped parts in the long hole and assemble the finished product onto the round rod.

[0021] In one possible design, the bottom of the die head is provided with a groove that matches the round rod, for accurately assembling the finished product onto the round rod during the stamping process.

[0022] In one possible design, the pad is detachably installed in the mounting groove to facilitate the replacement or maintenance of the limit rod.

[0023] In this application, during use, the stamped part is passed through the elongated hole, and one end of the stamped part abuts against one side of the limiting rod. At this time, the hydraulic rod can be activated, and the piston rod of the hydraulic rod drives the die head to move down. The die head stamps the stamped part, pushes the stamped finished product into the interior of the substrate, and presses it above the assembly. Since there is a groove at the bottom of the die head, the finished product can be assembled on the round rod and have an interference fit with the round rod, reducing subsequent processing steps.

[0024] After assembly, slightly lift the stamped part and push it forward so that the limiting rod engages inside the stamped hole, thus positioning the stamped part. The sliding box can be pulled out using the handle. At this time, the sliding box drives the roller to slide inside the long slide groove, thereby reducing resistance. After the sliding box is pulled out, the receiving box is exposed. The receiving box can be moved to one side, making it easy to take out the product and place the next assembly part. It is convenient to use.

[0025] Beneficial effects: The bottom of the die head has a groove, which allows the finished product to be directly assembled onto the round rod during the stamping process, with an interference fit between the finished product and the round rod. This avoids additional assembly processes, improves production efficiency, and reduces production costs.

[0026] After assembly, the stamped parts are slightly lifted and pushed forward so that the limiting rod engages inside the stamped hole, achieving precise positioning of the stamped parts, ensuring assembly quality and product consistency, and reducing the defect rate caused by inaccurate positioning.

[0027] The sliding box can be easily pulled out using the handle. The sliding box drives the rollers to slide within the long groove, reducing resistance during sliding and making operation more effortless and smoother. After the sliding box is pulled out, the receiving box is exposed, making it easy to remove the product and place the next assembly, improving production flow and convenience.

[0028] The mounting plate has a mounting groove on the top, and the mounting pad can be removed with screws. The pad is equipped with a limit rod. This structural design facilitates the installation, disassembly and replacement of various components, making it convenient for equipment maintenance and repair. It also makes it easy to adjust and modify the equipment according to different production needs. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0035] In one embodiment: Refer to Figure 1-4 An in-mold automatic assembly mechanism and stamping die are disclosed. During overall structure construction, a rectangular base plate 1 is prepared as the basic support component. Four support rods 6 are fixedly installed on the top of the base plate 1 by welding or bolts, ensuring that the four support rods 6 are vertical and evenly spaced. The tops of the four support rods 6 are then fixedly connected to the same rectangular top plate 4 by bolts, making the top plate 4 parallel to the base plate 1. A hydraulic rod 5 is fixedly installed at the center of the top of the top plate 4 by bolts, with the piston rod of the hydraulic rod 5 pointing vertically downwards.

[0036] A mounting plate 7, rectangular in shape and adapted to the size of the substrate 1, is bolted to the top of the substrate 1. A pressure plate 2, also rectangular in shape, is bolted to the top of the mounting plate 7. Holes, which are vertically connected, are formed inside corresponding positions on the pressure plate 2, mounting plate 7, and substrate 1 to allow the passage of subsequent stamped parts 9 and assemblies 19. An elongated hole 10 is formed at the center of the bottom of the pressure plate 2, with its length aligned with the length of the pressure plate 2.

[0037] A mounting groove 12 is formed on the top of the mounting plate 7, and the size of the mounting groove 12 is adapted to the pad 14. The pad 14 is detachably installed inside the mounting groove 12 by screws. Two symmetrically arranged limiting rods 13 are fixedly installed on one side of the top of the pad 14 by welding. The limiting rods 13 are perpendicular to the surface of the pad 14.

[0038] The stamped part 9 is placed inside the elongated hole 10. The stamped part 9 is elongated and has multiple mounting holes 11 inside, which are evenly distributed along the length of the stamped part 9. The position of the stamped part 9 is adjusted so that one end of it abuts against one side of the limiting rod 13, thus achieving initial positioning.

[0039] A rectangular hole 16 is formed on one side of the bottom of substrate 1, with the length of the rectangular hole 16 aligned with the length of substrate 1. A sliding box 8 is prepared, which is rectangular and its size is adapted to the rectangular hole 16. A handle 17 is welded to one end of the sliding box 8 for easy operation. Rollers 21 are bolted to both sides of the sliding box 8, with two rollers 21 installed on each side to ensure even distribution. Long, interconnected grooves 15 are formed on the inner walls of both sides of the rectangular hole 16, with the length of the long grooves 15 aligned with the length of the rectangular hole 16. The sliding box 8 is placed inside the rectangular hole 16, allowing the rollers 21 to slide along the direction of the long grooves 15 within the rectangular hole 16.

[0040] A receiving cavity 22 is formed on one side of the top of the sliding box 8. The size of the receiving cavity 22 is adapted to the receiving box 18. The receiving box 18 is snapped onto the side of the receiving cavity 22. The receiving box 18 is a rectangular box body, and an assembly 19 is placed inside. A round rod 20 is fixedly installed on the top of the assembly 19 by welding. The diameter of the round rod 20 is adapted to the diameter of the mounting round hole 11 on the stamped part 9 so as to achieve an interference fit.

[0041] During operation, hydraulic rod 5 is activated, and its piston rod drives the die head 3 downward. The die head 3 has a specific shape with a groove at its bottom that matches the assembly requirements. The die head 3 passes through the holes in the pressure plate 2, mounting plate 7, and base plate 1 to stamp the stamped part 9. During the stamping process, the die head 3 presses the stamped part 9 into the required shape and pushes the stamped product into the interior of the base plate 1, continuing to press it down until the finished product is pressed above the assembly part 19. Because of the groove at the bottom of the die head 3, the finished product is assembled onto the round rod 20 under pressure, achieving an interference fit with the round rod 20, completing automatic in-mold assembly, reducing subsequent processing steps, improving production efficiency, avoiding collisions and wear during part transfer, and ensuring product quality.

[0042] After assembly, the operator pulls the sliding box 8 outward using handle 17. The sliding box 8 drives the roller 21 to slide inside the long slide groove 15. The rolling of the roller 21 reduces resistance during the sliding process, making the operation more effortless. After the sliding box 8 is pulled out, the receiving box 18 is exposed. The operator moves the receiving box 18 to one side to facilitate the removal of the assembled product. After removing the product, the next assembly part 19 is placed in the receiving box 18, and then the sliding box 8 is pushed back into the rectangular hole 16 for the next stamping assembly operation. The entire process is accurately positioned, reducing the production of defective products and lowering production costs and resource waste.

[0043] This application can be used in the field of mold making, or in other fields applicable to this application.

[0044] In another embodiment: Reference Figure 1-4 An in-mold automatic assembly mechanism is used in the mold industry. A receiving cavity 22 is opened on one side of the top of the sliding box 8. The size of the receiving cavity 22 is adapted to the receiving box 18. The receiving box 18 is snapped onto the side of the receiving cavity 22. The receiving box 18 is a rectangular box body, and an assembly 19 is placed inside. A round rod 20 is fixedly installed on the top of the assembly 19 by welding. The diameter of the round rod 20 is adapted to the diameter of the mounting round hole 11 on the stamped part 9 to achieve an interference fit.

[0045] However, as is well known to those skilled in the art, the working principle and wiring method of the hydraulic rod 5 are conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
