Description

Technical Field

[0001] This utility model relates to the field of mold unloading technology, specifically a precise positioning automatic flipping hole rapid unloading device. Background Technology

[0002] Currently, some products have built-in flip-hole features, which can lead to issues such as material not being ejected and inconsistent flip-hole heights after the holes are flipped. Since the mold lacks a material ejection device during production, this can severely affect the part ejection efficiency. Forcibly removing parts can also cause product deformation and waste, and may even lead to missed parts and the risk of mold breakage. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model proposes a precise positioning automatic flipping and rapid unloading device. This device enables the unloading of flipped products while maintaining precise positioning without affecting the product's main dimensions, thereby improving production efficiency and reducing safety hazards.

[0004] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0005] A precise positioning automatic flipping and rapid unloading device includes:

[0006] A perforated die, on which the product is placed;

[0007] The punch is located above the die and works with the die to perform stamping.

[0008] The positioning ejector is vertically slidably installed inside the flipping die and is used for stripping the product after stamping.

[0009] As a further improvement of the utility model, an upper pressure plate is provided above the piercing die, and the piercing punch is slidably installed inside the upper pressure plate.

[0010] As a further improvement to the utility model, a lower pad block is provided at the bottom of the piercing die.

[0011] As a further improvement to the utility model, a rectangular spring is provided inside the piercing die and at the bottom of the positioning ejector.

[0012] As a further improvement to the utility model, the top of the positioning ejector is in the shape of a round pin, which is compatible with the pre-punching holes of the product.

[0013] As a further improvement of the utility model, the bottom of the positioning ejector is provided with a limiting edge that cooperates with the inside of the piercing die for sliding and limiting.

[0014] As a further improvement to the utility model, this positioning ejector is made of CR12MOV material that has undergone quenching treatment.

[0015] The beneficial effects of this utility model are:

[0016] This invention provides a precise positioning automatic flipping and rapid unloading device, which can achieve stable output of such products, improve production speed, ensure product quality, and reduce safety risks. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1 As shown, a precise positioning automatic flipping and quick unloading device mainly consists of a flipping punch 1, an upper pressure plate 2, a flipping die 4, a positioning ejector 5, a rectangular spring 6, and a lower pad block 7.

[0024] The flipping punch 1 is vertically slidably installed inside the upper pressure plate 2, with a clearance fit. The flipping die 4 is located below the flipping punch 1 and the upper pressure plate 2, and is fixed on the lower pad 7. The positioning ejector 5 is made of CR12MOV material and has undergone quenching treatment. The positioning ejector 5 is vertically slidably installed inside the flipping die 4, with a clearance fit. The top of the positioning ejector 5 is a round pin, which is adapted to the flipping pre-punch hole of the product 3, ensuring that the flipped product is smoothly ejected while the top of the ejector accurately positions the product 3 when the flipping pre-punch hole is placed.

[0025] The bottom of the positioning ejector 5 is provided with a limiting edge that cooperates with the inside of the flipping die 4 for sliding and limiting, thereby controlling the floating height of the positioning ejector 5. The rectangular spring 6 is disposed inside the flipping die 4 and located below the positioning ejector 5, and the rectangular spring 6 provides power to the positioning ejector 5.

[0026] Working principle and usage process of this utility model:

[0027] When using it, the initial state is as follows: Figure 1 As shown, product 3 is placed on the flanging die 4. The pre-punched holes on product 3 mate with the top of the circular pin of the positioning ejector 5. Then, the machine tool drives the flanging punch 1 downward, and forming begins. Under the action of the flanging punch 1, the positioning ejector 5 moves downward, the rectangular spring 6 is compressed, and the positioning ejector 5 moves downward synchronously, completing the stamping process. Figure 2 As shown.

[0028] During the return stroke of the punch, the flipping punch 1 moves upward, the rectangular spring 6 releases pressure, and the rectangular spring 6 drives the positioning ejector 5 upward at the same time. When the limiting edge working surface at the bottom of the positioning ejector 5 contacts the corresponding step inside the flipping die 4, the positioning ejector 5 is limited. During this process, the positioning ejector 5 contacts the flipping straight section on the product 3, thereby lifting the product 3 to a safe distance, and the employee picks up the part.

[0029] In this project, the dimensions and stroke of the positioning ejector 5 need to be determined based on the hole height and size of various products. To ensure the accuracy of the positioning ejector 5, it will be quenched using CR12MOV material.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
