A demolding mechanism for metal nameplate processing molds

Abstract

This utility model belongs to the field of nameplate manufacturing technology, and in particular to a demolding mechanism for metal nameplate processing molds. It includes a lower fixed plate and an upper fixed plate. A mold foot and an ejector cylinder are respectively mounted on the lower fixed plate. A concave template is mounted on the top of the mold foot. A material feeding module is hinged inside the mold cavity of the concave template, and the lower end of the material feeding module is hinged to the output end of the ejector cylinder. Guide pillars are embedded around the concave template. In this utility model, during stamping, the ejector block, in conjunction with highly elastic urethane pillars, conforms tightly to the nameplate as the mold cavity deforms. After the upper mold is raised, the highly resilient urethane pillars drive the ejector block to push the nameplate upwards, achieving initial separation of the nameplate from the mold cavity. Then, the ejector cylinder drives the upper part of the material feeding module to tilt up at a certain angle, causing the module to further open the nameplate from the mold cavity. This allows the formed metal nameplate to quickly separate from the mold cavity and discharge material, thereby significantly shortening the demolding time and ensuring production continuity.

Description

Technical Field

[0001] This utility model relates to the field of nameplate manufacturing technology, specifically a demolding mechanism for metal nameplate processing molds. Background Technology

[0002] Metal nameplates are made from metal materials such as copper, iron, aluminum, zinc alloy, titanium, and stainless steel. They are produced through processes such as stamping, die casting, etching, printing, enamel, imitation enamel, baking paint, epoxy resin, and electroplating. They serve as labels with physical properties, including instructions for use, trademarks, switch indicators, equipment nameplates, and decorative advertising. They are mainly used in the fields of electronic products, home appliances, machinery, and consumer products.

[0003] There are five common types of metal nameplates: rectangular (including square), round, oval, fan-shaped, and triangular. Rectangular metal nameplates are rectangular signs made of metal. When making rectangular metal nameplates, the metal blank needs to be placed in a forming mold and stamped by a stamping machine. Because the extruded metal nameplate fits too tightly with the mold cavity, it is difficult for workers to remove it quickly. If each removal operation takes a long time, it will delay the overall processing progress and is not conducive to actual production and processing needs.

[0004] Therefore, we propose a demolding mechanism for metal nameplate processing molds to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a demolding mechanism for metal nameplate processing molds, which solves the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0009] A demolding mechanism for a metal nameplate processing mold includes a lower fixed plate and an upper fixed plate.

Guide pillars are embedded around the concave template. Guide sleeves are embedded around the upper fixed plate, and the guide sleeves and guide pillars are sleeved together. A convex template is installed at the bottom of the upper fixed plate, and a cutting edge insert is embedded in the convex template. Uriage rubber pillars are embedded in both the cutting edge insert and the mold cavity of the concave template, and top blocks are connected to the urethane rubber pillars.

[0010] Furthermore, the mold feet are located on both sides of the lower fixed plate, and a limit switch is installed on the ejector cylinder.

[0011] Furthermore, the cavity of the concave template is provided with a groove, and the material feeding module is located in the groove.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a demolding mechanism for metal nameplate processing molds, which has the following beneficial effects:

[0019] In this invention, during stamping, the ejector block, in conjunction with highly elastic urethane pillars, tightly adheres to the nameplate as the mold cavity deforms. After the upper mold is raised, the highly resilient urethane pillars drive the ejector block to push the nameplate upwards, achieving initial separation between the nameplate and the mold cavity. Then, the ejector cylinder drives the upper part of the unloading module to tilt up at a certain angle, causing the module to further open the nameplate from the mold cavity. This allows the formed metal nameplate to quickly separate from the mold cavity and discharge material, thereby significantly shortening the demolding time and ensuring continuous production.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example

[0027] like Figures 1-4 As shown in the figure, an embodiment of the present invention discloses a demolding mechanism for a metal nameplate processing mold, comprising a lower fixed plate 1 and an upper fixed plate 2. A mold foot 3 and an ejector cylinder 4 are respectively mounted on the lower fixed plate 1. A concave template 5 is mounted on the top of the mold foot 3. A feeding module 6 is hinged within the mold cavity of the concave template 5, and the lower end of the feeding module 6 is hinged to the output end of the ejector cylinder 4. Guide posts 7 are inlaid around the concave template 5. Guide sleeves 8 are inlaid around the upper fixed plate 2, and the guide sleeves 8 and guide posts 7 are interlocked. A convex template 9 is mounted on the bottom of the upper fixed plate 2, and a cutting edge insert 10 is inlaid in the convex template 9. Both the cutting edge insert 10 and the mold cavity of the concave template 5 are embedded with urethane pillars 11, and the urethane pillars 11 are connected to top blocks 12. During stamping, the top blocks 12, together with the highly elastic urethane pillars 11, tightly adhere to the nameplate as the mold cavity deforms. After the upper mold is raised, the highly resilient urethane pillars 11 drive the top blocks 12 to push the nameplate upward, achieving the initial separation of the nameplate from the mold cavity. Then, the ejector cylinder 4 drives the upper part of the unloading module 6 to tilt up at a certain angle, so that the module further expands the nameplate from the mold cavity, thereby enabling the formed metal nameplate to be quickly separated from the mold cavity and discharged, thus greatly shortening the demolding time and ensuring production continuity.

[0028] like Figure 1 As shown, in some embodiments, the mold feet 3 are located on both sides of the lower fixed plate 1, and the ejector cylinder 4 is equipped with a limit switch 13. The main function of the mold feet 3 is to provide movement space for the ejector cylinder 4 through its own height, so as to avoid the ejection action being blocked. The limit switch 13 is mainly used to detect the position of the cylinder piston, control the movement stroke of the cylinder, and ensure that it works within the specified range.

[0029] like Figure 1As shown, in some embodiments, the cavity of the concave template 5 is provided with a groove 14, and the feeding module 6 is located in the groove 14. The main function of the groove 14 is to provide movement space for the feeding module 6 and avoid obstruction of the ejection action.

[0030] like Figure 3 As shown, in some embodiments, a guide groove 15 is provided on one side of the concave template 5, and the guide groove 15 corresponds to the mold cavity position of the concave template 5. The guide groove 15 guides the material to slide out of the mold along a predetermined path by tilting angle.

[0031] like Figure 1 As shown, in some embodiments, the lower end of the feeding module 6 is provided with a waist-shaped hole 16, and the output end of the ejector cylinder 4 is hinged to the waist-shaped hole 16 by a pin. The function of the waist-shaped hole 16 is to allow the connecting parts to move or adjust their position within a certain range while maintaining connection stability, which is suitable for scenarios that require fine adjustment or dynamic stress.

[0032] like Figure 1 As shown, in some embodiments, a die shank 17 is installed on the top of the upper fixed plate 2, and the cutting edge insert 10 corresponds to the die cavity position of the concave die plate 5. The core function of the die shank 17 is to rigidly connect the upper die part with the slide block of the press, so as to ensure that the upper die can move synchronously with the slide block, thereby completing the stamping process. The cutting edge insert 10 is used to complete the blanking process.

[0033] like Figure 2 As shown, in some embodiments, both the cutting edge insert 10 and the concave template 5 are provided with a recessed groove 18, and the urethane column 11 is fixed in the recessed groove 18. The recessed groove 18 is used to increase the installation space for the urethane column 11 and the top block 12.

[0034] like Figure 2 As shown, in some embodiments, the cutting edge insert 10 and the top block 12 in the mold cavity of the concave template 5 correspond to each other, and the top block 12 is flush with the bottom of the cutting edge insert 10 and the top of the mold cavity of the concave template 5, respectively. During stamping, the top block 12, together with the highly elastic urethane column 11, tightly fits the nameplate with the deformation of the mold cavity. After the upper mold is lifted, the highly resilient urethane column 11 drives the top block 12 to push the nameplate upward, realizing the initial separation of the nameplate from the mold cavity.

[0035] During use, when stamping, the ejector block 12, together with the highly elastic urethane pillar 11, conforms tightly to the nameplate as the mold cavity deforms. After the upper mold is raised, the highly resilient urethane pillar 11 drives the ejector block 12 to push the nameplate upward, achieving initial separation between the nameplate and the mold cavity. Then, the ejector cylinder 4 drives the upper part of the unloading module 6 to tilt up at a certain angle, causing the module to further open the nameplate from the mold cavity. This allows the formed metal nameplate to be quickly separated from the mold cavity and discharged, thereby significantly shortening the demolding time and ensuring production continuity.

[0036] In summary, during stamping, the ejector block 12, together with the highly elastic urethane pillar 11, tightly adheres to the nameplate as the mold cavity deforms. After the upper mold is raised, the highly resilient urethane pillar 11 drives the ejector block 12 to push the nameplate upward, achieving initial separation between the nameplate and the mold cavity. Then, the ejector cylinder 4 drives the upper part of the unloading module 6 to tilt up at a certain angle, causing the module to further open the nameplate from the mold cavity. This allows the formed metal nameplate to quickly separate from the mold cavity and discharge material, thereby significantly shortening the demolding time and ensuring production continuity.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
