[0006] For further optimization, an ejection mechanism is provided at the lower part of the movable lower mold core, and the movable lower mold core is consistent in height with the molding trimming knife after being ejected.

[0007] Further optimized, products are placed on the movable lower mold core and the end surface of the molding trimming knife.

[0008] Further optimized, the upper mold pressing edge ring is a movable structure, and the ejection height of the upper mold pressing edge ring is at least 2MM higher than the upper mold core surface.

[0009] Further optimized, the ejection mechanism is a push rod or a nitrogen cylinder that is extended and retracted to perform the ejection action.

[0010] Beneficial Effects

[0011] The cold plate mold for forming and trimming provided by the utility model utilizes the movable lower mold core as a control switch for trimming and the double material pressing effect of the upper mold pressing ring, so that the mold can play the trimming function again after ensuring that the mold is formed in place, and perfectly combines the functions of forming and trimming in a pair of engineering molds, thereby reducing the development cost of the mold, and at the same time reducing the costs of machine tools, labor, time, etc. required for production.

[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0020] Example

[0021] like Figure 1-7 As shown, a forming and trimming cold plate mold includes an upper mold part 1 and a lower mold part 2. The middle of the upper mold part 1 is provided with an upper mold core 5 and an upper mold edge pressing ring 6, and the middle of the lower mold part 2 is provided with a movable lower mold core 3 and a forming and trimming knife 4.

[0022] In this embodiment, an ejection mechanism is provided at the lower part of the movable lower mold core 3 , and the movable lower mold core 3 is at the same height as the molding trimming knife 4 after being ejected.

[0023] Products are placed on the end surfaces of the movable lower mold core 3 and the molding trimming knife 4.

[0024] The upper mold pressing edge ring 6 is a movable structure, and the ejection height of the upper mold pressing edge ring 6 is at least 2MM higher than the molding surface of the upper mold core 5.

[0025] The ejection mechanism is a push rod or a nitrogen cylinder that is extended and retracted to perform the ejection action.

[0026] The specific processing method of the mold:

[0027] The movable lower mold core is ejected, the mold surface and the molding trimming knife are at the same height, and the raw material will be placed stably on the movable lower mold core and the molding knife block; the upper mold edge ring is ejected, and the plane of the edge ring is at least 2MM higher than the highest point of the upper mold core mold surface; in the first half of the mold operation, the movable lower mold core relies on the ejector force or the nitrogen cylinder force to meet the molding force of the runner plate, and the upper mold edge ring provides the edge pressing force before the upper mold core contacts the movable lower mold core to control the molding state of the raw material; in the second half of the mold operation, as the upper and lower mold cores contact, the machine tool continues to press down, and the movable lower mold core slowly sinks, so that the molding trimming knife is exposed, and the upper mold edge ring continues to act as the trimming pressure after acting as the molding edge pressing role; the upper mold core is pressed into the lower mold molding trimming knife as the machine tool is pressed down, and forms a shear with the molding trimming knife to separate the formed parts from the process waste; the machine tool moves upward to open the mold, all the active strokes in the mold are released and returned to their positions, the movable lower mold core is ejected, and the material is taken manually.

[0028] Before the mold works, the lower mold part: the movable lower mold core is ejected, the mold surface and the molding trimming knife are at the same height, and the raw material will be placed stably on the movable lower mold core and the molding knife block; the upper mold part: the upper mold pressure ring is ejected, and the pressure ring plane is ejected at least 2MM higher than the highest point of the upper mold core mold surface;

[0029] In the first half of the mold working, the lower mold part: the movable lower mold core relies on the force of the ejector rod or the force of the nitrogen cylinder to meet the molding force of the runner plate; the upper mold part: the upper mold pressure ring provides pressure force before the upper mold core contacts the movable lower mold core, controls the molding state of the raw material, controls the feeding speed, avoids wrinkles when the raw material is molded, and increases the elongation rate of the raw material molding, thereby promoting a certain rigidity of the raw material after molding.

[0030] In the second half of the mold operation, the lower mold part: after the upper and lower mold cores come into contact, the machine tool continues to press down, and the movable lower mold core slowly sinks, exposing the forming trimming knife: the upper mold part: after the upper mold edge pressing ring plays the role of forming edge pressing, it continues to play the role of trimming pressing material. As the machine tool presses down, the upper mold core penetrates into the lower mold forming trimming knife, forms a shear with the forming trimming knife, separates the formed parts from the process waste, and completes the forming and trimming functions of the mold.

[0031] After the mold is working, the machine tool moves upward to open the mold, all active strokes in the mold are released and returned to their positions, and the movable lower mold core is ejected to facilitate manual material removal.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the utility model content within the protection scope of the utility model.
