Description

Technical Field

[0001] This utility model belongs to the field of mold technology, specifically relating to a large mold with a top plate support structure. Background Technology

[0002] Molds are key tools used in industrial production for molding materials (such as metals, plastics, and rubber), and are widely used in manufacturing processes such as injection molding, die casting, and stamping. Their basic structure typically includes a mold base, cavity, core, ejection mechanism (including ejector plate and ejector pins), guiding components (guide pillars and guide sleeves), and a cooling system. Among these, the ejector plate, as the core component of the ejection mechanism, is responsible for ejecting the product from the cavity after molding; its motion accuracy and stability directly affect product quality and production efficiency.

[0003] For large molds (such as injection molds with a clamping force of over 2500 tons), the weight of the top plate often exceeds 1000 kg due to the need to mold complex or large workpieces. These molds are widely used in the automotive, home appliance, and aerospace industries, for example, in the production of car bumpers, dashboards, or large appliance housings. However, because the weight of the top plate is mainly borne by the guide pillars and guide sleeves, under long-term high-load conditions, the inner wall of the guide sleeve and the surface of the guide pillar are prone to tensile damage, jamming, or even breakage due to concentrated loads. Utility Model Content

[0004] The purpose of this invention is to provide a large mold with a top plate support structure, which solves the problem that the weight of the top plate is mainly borne by the guide pillars and guide sleeves, and therefore the inner wall of the guide sleeve and the surface of the guide pillars are prone to tensile damage, jamming or even breakage due to concentrated loads under long-term high-load conditions.

A rectangular ring is fixedly connected to the upper surface of the slider. Wear-resistant supporting blocks are fitted to the inner wall of the rectangular ring, the upper surface of the slider, and the bottom of the top plate. A trapezoidal groove is opened at the bottom of the slider. A trapezoidal block is fitted to the bottom of the slider. Adjustment brackets are fixedly connected to the bottom of the trapezoidal block and the front and rear sides of the rectangular tube.

[0007] The present invention is further configured such that the adjusting bracket includes a threaded column, a bearing, a connecting plate, a rotating block, a threaded cylinder, and a connecting block. The surface of the threaded column is fixedly connected to the inner ring of the bearing, the outer ring of the bearing is fixedly connected to the inner wall of the connecting plate, the front and rear sides of the rectangular cylinder are fixedly connected to the surface of the connecting plate, the back side of the rotating block is fixedly connected to the front side of the threaded column, the surface of the threaded column is threadedly connected to the inner wall of the threaded cylinder, the surface of the threaded cylinder is fixedly connected to the inner wall of the connecting block, the surface of the connecting block is in contact with the inner wall of the rectangular cylinder, and the upper surface of the connecting block is fixedly connected to the bottom of the trapezoidal block.

[0008] The present invention is further configured such that the shape of the trapezoidal block is the same as the shape of the trapezoidal groove, and the front surface of both the trapezoidal block and the front surface of the trapezoidal groove are inclined surfaces.

[0012] The technical effects achieved by this utility model are as follows:

[0013] This utility model discloses a large mold with a top plate support structure. It comprises a rectangular cylinder, a rectangular hole, a slider, a rectangular ring, a support wear-resistant block, a trapezoidal groove, a trapezoidal block, and an adjusting bracket. When the trapezoidal block and the trapezoidal groove are misaligned, the slider is supported by the trapezoidal block and the adjusting bracket, ensuring close contact between the support wear-resistant block and the top plate. At this point, the weight of the top plate is distributed to the support wear-resistant block, reducing the stress on the guide pillars and guide sleeves, thus preventing damage due to excessive stress. Simultaneously, when the trapezoidal block and the trapezoidal groove are aligned, the weight of the slider separates the support wear-resistant block from the top plate, ensuring the distance between them is greater than the height of the rectangular ring. This allows for rapid replacement of the worn support wear-resistant block.

[0014] This utility model discloses a large mold with a top plate support structure. By setting a groove, a test plate, and a U-shaped column, the user can intuitively judge the wear condition of the support wear block by pulling the puller and observing the pulling force required to move the test plate after hanging the hook on the U-shaped column. Furthermore, the combination of the groove, test plate, and U-shaped column makes it easy for the user to measure the wear condition of the support wear block. At the same time, the combination of the ring, bolt, and nut allows the user to fix the test plate in the groove. Attached Figure Description

Detailed Implementation

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] like Figures 1 to 13 As shown, a large mold with a top plate support structure includes a right mold 1, a left mold 2 attached to the left side of the right mold 1, a guide post 3 fixedly connected to the left side of the left mold 2, a vertical plate 4 fixedly connected to the left side of the guide post 3, an ejection hole 5 on the left side of the left mold 2, an ejector pin 6 attached to the inner wall of the ejection hole 5, a top plate 7 fixedly connected to the left side of the ejector pin 6, a through hole 8 inside the top plate 7, a guide sleeve 9 fixedly connected to the inner wall of the through hole 8, the inner wall of the guide sleeve 9 being attached to the surface of the guide post 3, a horizontal plate 10 fixedly connected to the right side of the vertical plate 4 and the left side of the left mold 2, and a rectangular... The rectangular tube 11 has a rectangular hole 12 on its upper surface. A slider 13 is fitted into the inner wall of the rectangular hole 12. A rectangular ring 14 is fixedly connected to the upper surface of the slider 13. Wear-resistant support blocks 15 are fitted into the inner wall of the rectangular ring 14, the upper surface of the slider 13, and the bottom of the top plate 7. A trapezoidal groove 16 is opened at the bottom of the slider 13. A trapezoidal block 17 is fitted into the bottom of the slider 13. The shape of the trapezoidal block 17 is the same as that of the trapezoidal groove 16. The front of the trapezoidal block 17 and the front of the trapezoidal groove 16 are both inclined surfaces. Adjustment brackets 18 are fixedly connected to the bottom of the trapezoidal block 17 and the front and rear sides of the rectangular tube 11.

[0034] The adjusting bracket 18 includes a threaded column 181, a bearing 182, a connecting plate 183, a rotating block 184, a threaded cylinder 185, and a connecting block 186. The surface of the threaded column 181 is fixedly connected to the inner ring of the bearing 182, and the outer ring of the bearing 182 is fixedly connected to the inner wall of the connecting plate 183. The front and rear sides of the rectangular cylinder 11 are fixedly connected to the surface of the connecting plate 183. The back side of the rotating block 184 is fixedly connected to the front side of the threaded column 181. The surface of the threaded column 181 is threadedly connected to the inner wall of the threaded cylinder 185. The surface of the threaded cylinder 185 is fixedly connected to the inner wall of the connecting block 186. The surface of the connecting block 186 is in contact with the inner wall of the rectangular cylinder 11. The upper surface of the connecting block 186 is fixedly connected to the bottom of the trapezoidal block 17.

[0035] It should be noted that the rectangular ring 14 can be used to position the wear-resistant support block 15 above the slider 13. When the trapezoidal block 17 is misaligned with the trapezoidal groove 16, the slider 13 is supported by the trapezoidal block 17 and the adjusting bracket 18, and the wear-resistant support block 15 is in close contact with the top plate 7. At this time, the weight of the top plate 7 is distributed to the wear-resistant support block 15, and the force on the guide post 3 and the guide sleeve 9 is reduced, so that the guide post 3 and the guide sleeve 9 will not be damaged due to excessive force. At the same time, when the trapezoidal block 17 is aligned with the trapezoidal groove 16, the gravity of the slider 13 separates the wear-resistant support block 15 from the top plate 7, and the distance between the wear-resistant support block 15 and the top plate 7 is greater than the height of the rectangular ring 14. At this time, the worn wear-resistant support block 15 can be quickly replaced. Through the cooperation of the threaded post 181 and the threaded cylinder 185, the user can align or misalign the trapezoidal block 17 with the trapezoidal groove 16 by rotating the rotating block 184.

[0036] like Figures 1 to 14 As shown, a groove 19 is provided at the bottom of the top plate 7. A test plate 20 is attached to the inner wall of the groove 19 and the upper surface of the support wear-resistant block 15. A U-shaped column 21 is fixedly connected to the upper surface of the test plate 20.

[0037] Among them, a ring 22 is fixedly connected to the inner wall of the U-shaped column 21, and a bolt 23 is fitted to the inner wall of the ring 22. A nut 24 is fixedly connected to the front of the top plate 7. The inner wall of the nut 24 is threadedly connected to the surface of the bolt 23. The ring 22 is located in the middle of the U-shaped column 21, and the width of the ring 22 is greater than the width of the U-shaped column 21.

[0038] It should be noted that when the user hangs the hook on the tensioner on the U-shaped post 21, the wear condition of the support wear block 15 can be intuitively judged by observing the tension required for the test plate 20 to move through the tensioner. Furthermore, the user can easily measure the wear condition of the support wear block 15 through the cooperation of the groove 19, the test plate 20 and the U-shaped post 21. At the same time, the user can fix the test plate 20 in the groove 19 through the cooperation of the ring 22, the bolt 23 and the nut 24.

[0039] The working principle of this utility model is as follows: First, by rotating the rotating block 184, the trapezoidal block 17 is aligned with the trapezoidal groove 16 under the cooperation of the threaded column 181 and the threaded cylinder 185. Then, by the gravity of the slider 13, the trapezoidal block 17 is made to fit against the inner wall of the trapezoidal groove 16, and the distance between the rectangular ring 14 and the top plate 7 is greater than the height of the support wear-resistant block 15. Then, the support wear-resistant block 15 is placed above the slider 13 and positioned by the rectangular ring 14. Then, by rotating the rotating block 184, the trapezoidal block 17 is offset from the trapezoidal groove 16 under the cooperation of the threaded column 181 and the threaded cylinder 185. At this time, the slider 13 is supported by the trapezoidal block 17 and the adjusting bracket 18, and the support wear-resistant block 15 is in close contact with the top plate 7. Then, the weight of the top plate 7 is distributed to the support wear-resistant block 15, and the force on the guide column 3 and the guide sleeve 9 is reduced, so that the guide column 3 and the guide sleeve 9 will not be damaged due to excessive force.

[0040] When it is necessary to replace the support wear-resistant block 15, first rotate the rotating block 184 to align the trapezoidal block 17 with the trapezoidal groove 16 under the cooperation of the threaded column 181 and the threaded cylinder 185. Then, by the gravity of the slider 13, the trapezoidal block 17 is made to fit against the inner wall of the trapezoidal groove 16, and the distance between the rectangular ring 14 and the top plate 7 is greater than the height of the support wear-resistant block 15. At this time, the support wear-resistant block 15 can be removed from the slider 13.

[0041] When it is necessary to measure the wear level of the support wear block 15, first unscrew the bolt 23 from the nut 24, then hang the hook on the tensioner on the U-shaped column 21, and then, by pulling the tensioner and observing the required tension of the test plate 20, the wear level of the support wear block 15 can be intuitively judged. After the measurement is completed, push the test plate 20 back to the designated position, then insert the bolt 23 into the ring 22 and screw the bolt 23 into the nut 24. At this time, the test plate 20 is fixed in the groove 19 by the cooperation of the bolt 23, nut 24 and ring 22.

[0042] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
