Description

Technical Field

[0001] The utility model belongs to the technical field of sheet material forming, in particular to a plastic suction convex typesetting die of a sheet material forming machine. Background Art

[0002] During sheet forming processing, a punch layout mold is required. In the existing technology, the spacing between the knife lines of ordinary punch layout is small, and the spacing does not match the size of the punch. After the mold is completed, ribs and thinness will appear during the mold trial process, resulting in unqualified molds. Utility Model Content

[0003] The purpose of the embodiment of the utility model is to provide a plastic blister punch typesetting mold for a sheet forming machine, which can improve the quality of sheet forming.

[0004] The utility model embodiment is achieved as follows:

[0005] A blister punch layout mold for a sheet forming machine comprises: a mold base and a punch, wherein the punch protrusion is arranged on the mold base, and the punches are distributed on the mold base. The spacing between adjacent punches is 1.2 times or more of the punch height, and at least half of the spacing between adjacent punches is preset around the mold base as a punch-free area; wherein adjacent punches are adjacent punches in the horizontal direction or the vertical direction, and their spacing is the horizontal spacing or the vertical spacing of the adjacent punches.

[0006] Wherein, the punches are triangular punches, the punches in the same horizontal direction are arranged in sequence in the same direction, and the punches in the same vertical direction are arranged in sequence in the opposite direction.

[0007] The embodiment of the utility model effectively solves the problem of ribs and thinness occurring during the mold trial process by adjusting the distance between the convex molds of the mold layout, so that the formed sheet has small stretching marks and uniform thickness, effectively ensuring the quality of sheet forming. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a structural diagram of the plastic blister punch typesetting mold of the utility model. DETAILED DESCRIPTION

[0009] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0010] The following describes the specific implementation of the present invention in detail with reference to specific embodiments:

[0011] like Figure 1 As shown, a blister punch layout mold for a sheet forming machine includes: a mold base 1 and a punch 2, wherein the punch protrusion is arranged on the mold base, and the punches are distributed on the mold base. The spacing between adjacent punches is 1.2 times or more of the punch height, and at least half of the spacing between adjacent punches is preset around the mold base as a punch-free area; wherein adjacent punches are adjacent punches in the horizontal direction or the vertical direction, and their spacing is the horizontal spacing or the vertical spacing of the adjacent punches.

[0012] In the figure, the punches are triangular, with the punches in the same horizontal direction arranged in the same direction, and the punches in the same vertical direction arranged in the opposite direction. By arranging the punches in the same and opposite directions, the mold base can be equipped with as many punches as possible, improving the efficiency of one-shot molding.

[0013] When the mold is forming the sheet, since the spacing between adjacent punches is 1.2 times or more of the punch height, the spacing is sufficient, the sheet will not have ribs, the forming stress of the sheet is sufficiently released, and it will not be too thin. In this way, the sheet forming effect will be good and the forming quality will be improved. There are also empty areas reserved around the mold base, and the sheet has a stress buffer zone. In this way, for the punches close to the four sides of the mold base, the forming quality can be guaranteed.

[0014] In the embodiment of the present invention, the distance between the convex dies of the mold layout is adjusted, which effectively solves the problems of ribs and thinness that occur during the mold trial process, so that the formed sheet has small stretching marks and uniform thickness, effectively ensuring the quality of sheet forming.

[0015] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
