Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing mold technology, specifically an automotive parts processing mold that is easy to eject. Background Technology

[0002] Automotive parts are the various units that make up a car and the products that serve the car. Stamping is a common production method for automotive parts. Stamping requires the use of stamping dies, but existing automotive parts processing dies still have certain shortcomings, such as:

[0003] The application CN202021250708.X, entitled "A Stamping Die for Processing Automotive Parts," lacks an ejection function during use, making it impossible to eject the stamped automotive parts for unloading. This forces operators to use additional tools or perform manual operations to remove the parts, which not only consumes a lot of time but also easily damages the parts during the unloading process, reducing the product qualification rate and hindering the improvement of automotive parts processing efficiency. It is difficult to meet the growing demand for large-scale and high-efficiency production in the automotive industry and has limitations in application. In view of this, a processing die for automotive parts that facilitates ejection is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an easy-to-eject automotive parts processing mold, so as to solve the problem mentioned in the background art that the existing automotive parts processing molds do not have the function of ejecting automotive parts, which affects the processing efficiency of automotive parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a processing mold for automotive parts that facilitates ejection, comprising a base plate and support legs disposed at the four corners of the bottom surface of the base plate.

[0006] A lower mold is fixedly installed on the top surface of the base plate, and an upper mold is movably arranged above the lower mold. The upper mold matches the mold cavity opened at the top of the lower mold. An ejector plate is movably arranged inside the lower mold, and the length and width dimensions of the ejector plate match the length and width dimensions of the mold cavity at the top of the lower mold.

[0007] The above technical solution facilitates the automatic ejection of automotive parts after stamping.

[0008] As a preferred embodiment of this utility model, a fixing frame is fixedly installed on the top surface of the base plate, and a hydraulic cylinder is fixedly installed on the top surface of the fixing frame. The output shaft of the hydraulic cylinder moves through the top of the fixing frame, and an mounting plate is fixedly installed at the end of the output shaft of the hydraulic cylinder. The bottom surface of the mounting plate is fixedly connected to the top surface of the upper mold.

[0009] The above technical solution facilitates the lifting and moving of the mounting plate and upper mold by driving the hydraulic cylinder.

[0010] As a preferred embodiment of this utility model, movable plates are provided on both the left and right sides of the lower mold, and the two movable plates slide longitudinally through the base plate. A sliding rod is provided transversely through the movable plates. Push blocks are fixedly installed on both the left and right end faces of the mounting plate, and the outer end face of the push block and the inner end face of the sliding rod are inclined surfaces that match each other. A vertical plate is fixedly installed on the outer end of the sliding rod, and a tension spring is sleeved on the outer side of the sliding rod. The inner end of the tension spring is fixedly connected to the outer side of the movable plate, and the outer end of the tension spring is fixedly connected to the inner side of the vertical plate.

[0011] By adopting the above technical solution, it is easy for the push block to move downward with the mounting plate and push the slide rod to move outward. After the push block continues to move downward and separates from the slide rod, the slide rod at both ends of the tension spring will reset and move, ensuring that the push block is placed below the slide rod.

[0012] As a preferred embodiment of this utility model, a limiting rod is fixedly installed on the outer side of the movable plate, and the limiting rod is located below the sliding rod, and the outer end face of the limiting rod is in movable contact with the inner side of the upright plate.

[0013] By adopting the above technical solution, it is easy to limit the position of the upright plate and the sliding rod by setting the limiting rod, so as to ensure that the sliding rod is in a position that matches the push block.

[0014] As a preferred embodiment of this utility model, a connecting plate is fixedly installed at the bottom end of the movable plate, and a push rod is fixedly installed on the top surface of the connecting plate. The push rod slides through the bottom plate and moves through the mold cavity opened at the top of the lower mold. The top end of the push rod is fixedly connected to the bottom surface of the ejector plate. A spring is sleeved on the outside of the push rod, and the top end of the spring is fixedly connected to the bottom surface of the bottom plate. The bottom surface of the spring is fixedly connected to the top surface of the connecting plate.

[0015] By adopting the above technical solution, when the mounting plate moves upward after stamping, the pusher pushes the slide rod and movable plate upward, so that the connecting plate moves the top rod and ejector plate upward to eject the automotive parts.

[0016] As a preferred embodiment of this utility model, a push rod is provided above the upright plate, and the push rod is fixedly installed on the inner top surface of the fixing frame, and the bottom surface of the push rod and the bottom surface of the upright plate are inclined surfaces that match each other.

[0017] By adopting the above technical solution, it is easy for the slide bar and the movable plate to move continuously upward. After the vertical plate abuts against the top rod, the vertical plate and the slide bar move outward, thereby separating the slide bar from the push block. This ensures that the movable plate and the slide bar move downward to reset, thereby causing the connecting plate to drive the top rod and the ejector plate to reset downward.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the easy-to-eject automotive parts processing mold can automatically eject the automotive parts after stamping, without the need for manual removal with additional tools, avoiding damage to the parts caused by improper operation during manual removal, reducing the defect rate of the product, improving the product qualification rate, ensuring the quality stability of the automotive parts, and shortening the processing cycle of a single part, significantly improving the processing efficiency of automotive parts, and meeting the needs of large-scale and high-efficiency production in the automotive industry;

[0019] 1. The mounting plate and upper mold can be lifted and moved by the hydraulic cylinder, ensuring that the upper mold can move downward and close with the upper mold, thereby realizing the stamping processing of automotive parts;

[0020] 2. The mounting plate moves downward, causing the push block to move downward synchronously. When the push block contacts the slide rod, it pushes the slide rod outward and causes the vertical plate to move synchronously, stretching the tension spring. After the push block moves downward and separates from the slide rod, the tension spring pulls the vertical plate and slide rod to return to their original positions. At this time, the slide rod is positioned above the push block, ensuring that after the automotive parts are stamped, when the mounting plate, upper mold, and push block move upward, the push block pushes the slide rod and movable plate upward, causing the movable plate to drive the ejector rod and ejector plate upward to eject the automotive parts automatically without manual intervention.

[0021] 3. As the movable plate continues to move upward, the upright plate comes into contact with the push rod, pushing the upright plate and the slide rod outward, causing the slide rod to separate from the push block. At this time, the movable rod drives the connecting plate, the top rod, and the ejector plate to move downward to reset for subsequent use. Attached Figure Description

[0029] Please see Figure 1 - Figure 5 The present invention provides a processing mold for automotive parts that facilitates ejection, comprising a base plate 1 and support legs 2 disposed at the four corners of the bottom surface of the base plate 1. A lower mold 3 is fixedly installed on the top surface of the base plate 1, and an upper mold 4 is movably disposed above the lower mold 3. The upper mold 4 matches the mold cavity opened at the top of the lower mold 3. An ejector plate 5 is movably disposed inside the lower mold 3, and the length and width dimensions of the ejector plate 5 match the length and width dimensions of the mold cavity at the top of the lower mold 3.

[0030] A fixing frame 6 is fixedly installed on the top surface of the base plate 1, and a hydraulic cylinder 7 is fixedly installed on the top surface of the fixing frame 6. The output shaft of the hydraulic cylinder 7 moves through the top of the fixing frame 6, and an mounting plate 8 is fixedly installed at the end of the output shaft of the hydraulic cylinder 7. The bottom surface of the mounting plate 8 is fixedly connected to the top surface of the upper mold 4.

[0031] Movable plates 9 are provided on both the left and right sides of the lower mold 3. The two movable plates 9 slide longitudinally through the base plate 1. A slide rod 10 slides laterally through the movable plates 9. Push blocks 11 are fixedly installed on both the left and right ends of the mounting plate 8. The outer end face of the push block 11 and the inner end face of the slide rod 10 are inclined surfaces that match each other. A vertical plate 12 is fixedly installed on the outer end of the slide rod 10. A tension spring 13 is sleeved on the outer side of the slide rod 10. The inner end of the tension spring 13 is fixedly connected to the outer side of the movable plate 9. The outer end of the tension spring 13 is fixedly connected to the inner side of the vertical plate 12.

[0032] A limiting rod 14 is fixedly installed on the outer side of the movable plate 9, and the limiting rod 14 is located below the slide rod 10, and the outer end face of the limiting rod 14 is in movable contact with the inner side of the upright plate 12.

[0033] A connecting plate 15 is fixedly installed at the bottom of the movable plate 9, and a push rod 16 is fixedly installed on the top surface of the connecting plate 15. The push rod 16 slides through the bottom plate 1 and moves through the mold cavity opened at the top of the lower mold 3. The top end of the push rod 16 is fixedly connected to the bottom surface of the ejector plate 5. A spring 17 is sleeved on the outside of the push rod 16. The top end of the spring 17 is fixedly connected to the bottom surface of the bottom plate 1, and the bottom surface of the spring 17 is fixedly connected to the top surface of the connecting plate 15.

[0034] A push rod 18 is provided above the upright plate 12, and the push rod 18 is fixedly installed on the inner top surface of the fixing frame 6, and the bottom surface of the push rod 18 is an inclined surface that matches the bottom surface of the upright plate 12.

[0035] Working principle: When in use, the hydraulic cylinder 7 is activated to extend its output shaft, which causes the mounting plate 8 to move downward. The mounting plate 8 drives the upper mold 4 to move towards the lower mold 3. When the two are in contact, the mold cavity opened at the top of the upper mold 4 and the lower mold 3 are precisely matched to stamp the automotive part blank placed in the mold cavity to form it.

[0036] When the mounting plate 8 moves downward, it drives the push block 11 to move downward synchronously. After the push block 11 contacts the slide rod 10, it pushes the slide rod 10 to move outward, so that the upright plate 12 moves synchronously to a limit and stretches the tension spring 13. After the downward-moving push block 11 separates from the slide rod 10, the upright plate 12 and the slide rod 10 move inward to reset under the pulling action of the tension spring 13. At this time, the slide rod 10 will be above the push block 11.

[0037] After the stamping is completed, the output shaft of the hydraulic cylinder 7 retracts, causing the mounting plate 8 to move upward. The push blocks 11 at both ends of the mounting plate 8 move upward accordingly. After the push blocks 11 move upward and touch the bottom surface of the slide rod 10, they will push the slide rod 10 to move upward. The slide rod 10 will drive the movable plate 9 to move upward synchronously, so that the movable plate 9 drives the push rod 16 and the ejector plate 5 to move upward synchronously through the connecting plate 15 and compress the spring 17. The ejector plate 5 moves upward to eject the car parts.

[0038] When the movable plate 9 continues to move upward, and the upright plate 12 comes into contact with the push rod 18, it will push the upright plate 12 and the slide rod 10 to move outward, so that the slide rod 10 separates from the push block 11. At this time, under the release action of the spring 17, the connecting plate 15, the movable plate 9, the push rod 16 and the ejection plate 5 will move downward to reset and return to the initial position, preparing for the next stamping and ejection operation. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
