Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, in particular to a mold knife structure for trimming and discharging waste. Background Art

[0002] For a long time, the waste discharge problem of trimming molds has been bothering relevant personnel. In the production process, if the trimming waste is not discharged smoothly, it will often cause problems such as waste jamming and blockage, causing equipment shutdown, product defects, and even mold damage, which poses a great risk to the production line's production capacity, part quality, equipment safety, etc. Figure 1 The mold waste cutter structure shown in the figure cooperates with the lower mold cutter to cut the waste into multiple pieces when the upper mold cutter moves downward. However, due to the large width of the waste and the lower mold cutter along the feeding direction, the waste will be stuck at the upper end of the lower mold cutter and will not slide easily. In the case of automated production, the line needs to be stopped to clean up the waste. If the stuck waste is not found in time, the mold blade will be at risk of chipping and cracking due to excessive waste accumulation, affecting production efficiency. Therefore, it is necessary to invent a trimming and waste removal mold structure. Utility Model Content

[0003] The utility model aims to provide a trimming and waste material discharge die structure, which solves the problem that waste materials in the existing die structure are easily stuck on the upper end of the lower die knife and are difficult to slide off.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A trimming and waste removal die knife structure comprises a plurality of groups of upper die knives arranged side by side and a plurality of groups of lower die knives arranged at intervals, wherein the lower end of the upper die knife is provided with convex ribs extending to both side ends along the feeding direction, and the upper end of the lower die knife is provided with grooves extending to both side ends along the feeding direction, wherein the grooves are arranged toward the convex ribs, and the convex ribs cooperate with the grooves to bend the waste.

[0006] Furthermore, the convex ribs and the concave grooves are both arc structures.

[0007] Furthermore, a relief groove is provided at the lower end of the upper die cutter between the convex rib and the cutter head.

[0008] Furthermore, the avoidance groove extends to both side ends of the upper die cutter along the feeding direction.

[0009] Furthermore, the avoidance groove is a U-shaped structure with rounded corners.

[0010] The beneficial effects of the utility model: the utility model has a simple and practical structure. By respectively designing convex ribs and grooves on the upper die knife and the lower die knife, the length of the waste can be shortened while cutting off the waste, which plays a better role in escaping the material, makes the sliding of the material smooth, and is not prone to waste jamming. It can avoid damage to the mold and ensure production efficiency.

[0011] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] like Figures 2 to 4 The structure of a trimming and waste discharge die knife is shown, comprising a plurality of groups of upper die knives 1 arranged side by side and a plurality of groups of lower die knives 2 arranged at intervals, wherein the lower end of the upper die knife 1 is provided with a convex rib 11 extending to both side ends along the feeding direction, and the upper end of the lower die knife 2 is provided with a groove 21 extending to both side ends along the feeding direction, and the groove 21 is arranged toward the convex rib 11, and the convex rib 11 cooperates with the groove 21 to bend the waste 3.

[0017] Preferably, in combination with the above solution, in order to facilitate better deformation of the waste material and facilitate demoulding and blanking, the convex rib 11 and the groove 21 are both arc structures.

[0018] Preferably, in combination with the above solution, in order to prevent interference with the waste material 3 , a avoidance groove 12 is provided at the lower end of the upper die cutter 1 between the rib 11 and the cutter head 13 .

[0019] Preferably, in combination with the above solution, in order to better prevent interference with the waste material 3, the avoidance groove 12 extends to both side ends of the upper die cutter 1 along the feeding direction.

[0020] Preferably, in combination with the above solution, in order to better prevent interference problems, the avoidance groove 12 is a U-shaped structure with rounded corners.

[0021] The principle of the utility model is as follows: when the upper die is pressed downward, the upper die cutter 1 is driven to move downward; when the die is closed, the cutter head 13 of the upper die cutter 1 cuts the waste material 3 into a plurality of sections; at the same time, the convex rib 11 cooperates with the groove 21 to bend the waste material 3 into an arc-shaped structure, so that the waste material 3 is deformed as a whole, thereby shortening the length of the waste material 3 and reducing the contact surface with the lower die cutter 2, thereby making it easier to achieve blanking and avoiding the problem of waste material jamming.

[0022] It should be noted that all directional indications in the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0023] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or they are directly applied to other occasions without improvement, they all fall within the protection scope of the utility model.
