Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of stamping dies, and in particular to a progressive die with a parting mechanism. Background Technology
[0002] To enable a single product to meet the needs of multiple models, automakers often integrate all models into a single product and use molds to separate parts to achieve the functionality of each model. Since multiple models of the same product may exist, the normal mold-making logic would be to produce the product using a single mold and then separately create the corresponding parting mold. This would not only increase work efficiency but also significantly reduce development costs. However, the current problem is that creating a separate parting mold adds an extra parting step during production, increasing labor costs and the total production time for the entire project.

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0019] Please see Figure 1-5 This utility model discloses a continuous mold with a parting mechanism, comprising: an upper mold mechanism and a lower mold mechanism, wherein the upper mold mechanism includes an upper mold base 1, an upper pad 2, an upper clamping plate 3, a stop plate 4, and a stripper plate 5 arranged from top to bottom; the lower mold mechanism includes a lower template 6, a lower pad 7, a lower mold base 8, and a lower pad foot 9 arranged from top to bottom. Specifically, this utility model also includes a parting mechanism, which includes a horizontally sliding insert rod 10 disposed within the upper pad and a parting rod disposed within the upper clamping plate. The device includes a punch entry block 11, a blanking punch 12 inserted into a stop plate, a stripper entry block 13 inserted into a stripper plate, a blanking cutter 14 inserted into a lower die plate, and a waste channel 15 that is interconnected between the lower backing plate and the lower die base. The strip to be cut is placed between the stripper entry block and the blanking cutter. The stripper entry block has a hollow structure. The upper end of the blanking punch is fitted into the punch entry block, and the lower end passes through the cavity in the stop plate and the hollow structure of the stripper entry block in sequence before contacting the strip to be cut.
[0020] Specifically, the punch entry block 11 includes a first punch block 110 disposed within the first cavity of the upper clamping plate and a second punch block 111 engaged with the periphery of the first punch block. A spring element 112 is connected to the bottom of the second punch block, applying an upward force to the second punch block to press against the lower surface of the insert rod. The upper end of the feeding punch is fitted inside the punch entry block, and the lower end is used to punch the material strip placed between the stripper block and the feeding blade. In this embodiment, the first punch block is provided with a engaging groove. The second punch block is provided with a protrusion 113 that matches the snap-fit groove. The two cooperate to snap-fit and connect the first punch block and the second punch block. The first punch block has a cavity. The upper end of the feeding punch is inserted into the cavity and snap-fits with the first punch block, so that the feeding punch and the punch entry block are connected into a moving whole. When the insert rod is pulled outward to release the pressing effect on the punch entry block, the entire punch entry block and the feeding punch move upward under the action of the elastic element, so that the lower end of the feeding punch separates from the material strip.
[0021] Specifically, a second cavity is provided inside the upper pad plate. The insert rod is slidably disposed in the second cavity and can slide horizontally along the second cavity. The rear end of the insert rod extends outside the upper clamping plate, making it convenient for the operator to hold the insert rod and pull it outward. The front end of the insert rod has a first slope 101, and the front end of the second punch block has a second slope 114 that slides in cooperation with the first slope. When the insert rod is pulled out of the mold so that the first slope moves to contact the second slope, the insert rod releases its pressing effect on the punch entry block. When the unloading punch needs to separate the material, the manual pushes the insert rod into the mold so that the first slope of the insert rod moves to the position directly above the second punch block. The pull rod presses the entire punch entry block and the unloading punch downward to cut the material. Preferably, the shape of the hollow cavity of the unloading blade can be adapted to the shape of the material cut on the upper part of the strip, so that the cut waste material can fall smoothly into the waste channel and be discharged outside the machine.
[0022] Specifically, the rear end of the insert rod is provided with a U-shaped slot 102. When cutting is not required, the insert rod is pulled back out of the mold to make the first slope move to contact the second slope. It can be connected to the upper mold base threaded by a bolt passing through the U-shaped slot.
[0023] The beneficial effects of this utility model are: by integrating the parting mechanism into the mold, the material cutting punch is controlled by pushing and pulling the insert rod, thereby realizing the parting of the material strip, which greatly reduces the research and development cost of the entire production process and improves production efficiency.
[0024] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
