Description

Technical Field

[0001] This utility model relates to the field of hydraulic press mold technology, and in particular to an ejection structure for hydraulic press molds. Background Technology

[0002] In the industrial production sector, hydraulic press molds are core components of various molding processes. With the acceleration of industrialization, various industries have placed higher demands on product precision, quality, and production efficiency. The automotive manufacturing industry is a typical example. In order to achieve the goals of lightweight and high strength in automotive parts, new materials and complex molding processes are required. This requires hydraulic press molds to have more precise dimensional control, higher strength, and wear resistance. After the workpiece is produced, an ejector structure is needed to eject and demold it.

[0003] Existing ejection structures for hydraulic press molds often rely on cylinders installed inside the mold base to eject the formed workpiece. This method is inconvenient because the workpiece cannot be ejected simultaneously with the separation of the upper and lower molds. In each production cycle, because the workpiece cannot be ejected immediately upon mold separation, operators must wait for the cylinders to activate and complete the ejection action before proceeding with subsequent operations such as removing the workpiece or cleaning the mold cavity. This undoubtedly increases the production cycle time for a single workpiece. In large-scale production, this time loss due to design flaws in the ejection structure accumulates, hindering overall production efficiency and failing to meet growing market demands, thus impacting workpiece production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an ejection structure for hydraulic press molds, which solves the defect of existing ejection structures for hydraulic press molds that are inconvenient to eject the workpiece while the upper and lower molds are separating.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an ejection structure for a hydraulic press mold, including a mold base;

[0006] A guide mechanism is fixedly connected to the outer wall of the mold base, and a docking groove is provided inside the mold base;

[0007] The guiding mechanism includes a guide column fixedly installed on the top of the mold base, a top plate fixedly connected to the top of the guide column, a hydraulic rod installed inside the top plate, an upper mold fixedly connected to the output end of the hydraulic rod, and a docking block fixedly connected to the bottom of the upper mold.

[0008] The outer wall of the upper mold is fixedly connected to a demolding mechanism, which includes a slider fixedly installed on the outer wall of the upper mold, and a receiving plate is movably connected to the outer wall of the slider.

[0009] Preferably, the upper mold has an open design, and the upper mold and the guide post form a sliding structure, which allows the upper mold to slide along the guide post.

[0010] Preferably, the docking block is engaged with the mold seat via a docking groove, and the docking block is symmetrically arranged on the central axis of the upper mold, which can improve the stability of the docking and closing of the mold seat and the upper mold.

[0011] Preferably, the receiving plate has a sliding groove inside, a supporting base plate is fixedly connected to the outer wall of the receiving plate, a top rod is fixedly connected to the top of the supporting base plate, a return spring is fixedly connected to the top of the supporting base plate, and a guide groove is provided inside the mold base.

[0012] Preferably, the slider is T-shaped, and the slider and the receiving plate form a sliding structure through the slide groove, so that the slider can slide along the slide groove.

[0013] Preferably, the receiving plate is L-shaped and welded to the supporting base plate. The top rod is symmetrically arranged with respect to the central axis of the supporting base plate. The return spring is sleeved on the outer wall of the top rod, which can reset the top rod after it is pushed out.

[0014] Preferably, the ejector rod and the mold base form a sliding structure, and the support base plate forms a sliding structure with the mold base through the guide groove, which allows the ejector rod to eject the workpiece for demolding.

[0015] The present invention provides an ejection structure for a hydraulic press mold, the advantages of which are:

[0016] By using the mold base and guide mechanism, and by activating the hydraulic rod, the docking block fixedly connected to the bottom of the upper mold is driven into the docking groove, which can stably dock and close the mold base with the upper mold.

[0017] Furthermore, the sliding cooperation between the upper mold and the guide column can improve the stability of the upper mold's lifting and lowering, and further facilitate the opening and closing of the mold base and the upper mold;

[0018] With the mold base, guide mechanism and demolding mechanism set up, the upper mold moves upward and pulls the support plate to move, so that the push rod at the top of the support base plate slides along the mold base. This facilitates the demolding of the workpiece inside the mold base while the mold base and the upper mold are opened and separated, and further improves the efficiency of mass production of workpieces.

[0019] Furthermore, with the sliding of the slider and the groove, the upper mold will not be pushed out when it is initially separated from the mold base, thus preventing the workpiece from getting stuck on the upper mold due to synchronous ejection.

[0020] Furthermore, under the action of the return spring, when the upper mold moves down a portion, it can drive the ejector pin to move down and reset. Attached Figure Description

[0028] Please see Figures 1-5 The present invention provides an ejection structure for a hydraulic press mold, including a mold base 1.

[0029] Reference Figure 1 , Figure 2 and Figure 3 As shown, a guide mechanism 2 is fixedly connected to the outer wall of the mold base 1, and a docking groove 3 is provided inside the mold base 1. The guide mechanism 2 includes a guide post 21 fixedly installed on the top of the mold base 1. A top plate 22 is fixedly connected to the top of the guide post 21. A hydraulic rod 23 is installed inside the top plate 22. An upper mold 24 is fixedly connected to the output end of the hydraulic rod 23. A docking block 25 is fixedly connected to the bottom of the upper mold 24. The upper mold 24 has an open hole design. The upper mold 24 and the guide post 21 form a sliding structure. The docking block 25 is engaged with the mold base 1 through the docking groove 3. The docking block 25 is symmetrically arranged on the central axis of the upper mold 24.

[0030] By activating the hydraulic rod 23, the upper mold 24 can slide stably along the guide post 21, causing the docking block 25 fixedly connected to the bottom of the upper mold 24 to dock into the docking groove 3, so that the mold base 1 and the upper mold 24 can be stably docked and closed.

[0031] Reference Figure 1 , Figure 3 Figure 4 and Figure 5 As shown, a demolding mechanism 4 is fixedly connected to the outer wall of the upper mold 24. The demolding mechanism 4 includes a slider 41 fixedly installed on the outer wall of the upper mold 24. A receiving plate 42 is movably connected to the outer wall of the slider 41. A sliding groove 43 is opened inside the receiving plate 42. A supporting base plate 44 is fixedly connected to the outer wall of the receiving plate 42. A push rod 45 is fixedly connected to the top of the supporting base plate 44. A return spring 46 is fixedly connected to the top of the supporting base plate 44. A guide groove 5 is opened inside the mold base 1. The slider 41 is T-shaped. The slider 41 and the receiving plate 42 form a sliding structure through the sliding groove 43. The receiving plate 42 is L-shaped. The receiving plate 42 and the supporting base plate 44 are welded together. The push rod 45 is symmetrically arranged about the central axis of the supporting base plate 44. The return spring 46 is sleeved on the outer wall of the push rod 45. The push rod 45 and the mold base 1 form a sliding structure. The supporting base plate 44 and the mold base 1 form a sliding structure through the guide groove 5.

[0032] As the upper mold 24 moves upward and separates from the mold base 1, the slider 41 can slide upward along the receiving plate 42 under the action of the slide groove 43. When the slider 41 is in contact with the inner top wall of the slide groove 43, it will pull the receiving plate 42 to move upward, so that the support base plate 44 moves upward along the guide groove 5 opened inside the mold base 1. The ejector rod 45 can slide along the mold base 1 and eject the workpiece in the mold base 1. At this time, the return spring 46 is deformed due to compression. When the upper mold 24 moves downward, the ejector rod 45 at the top of the support base plate 44 can be reset under the action of the return spring 46, so that the next workpiece can be stamped.
