Description

Technical Field

[0001] The utility model relates to the technical field of demoulding equipment, in particular to a demoulding and ejecting device for a waterproof plug. Background Art

[0002] In the silicone injection molding production process, the molded product needs to be removed from the mold. This process is called demolding. There are two common demolding methods in production: manual demolding and mechanical demolding. Manual demolding refers to the use of tools to manually eject the product from the mold. The quality of this demolding method depends on the experience of the workers. The operation method is primitive, time-consuming and labor-intensive, easy to damage the product, and inefficient; mechanical demolding refers to the use of mechanical equipment, with the power mechanism providing the ejection force to eject all the products at once. Since there are a large number of products to be demolded at the same time, the power mechanism needs to provide a large ejection force. This operation is dangerous and easy to cause product damage. Utility Model Content

[0003] The utility model aims to provide a waterproof plug demoulding and ejecting device, which reduces the number of products demoulded at the same time without reducing the number of products demoulded at one time by changing the placement state of the cavity plate, reduces the pressure of the power mechanism, reduces the ejection force of the demoulding device on the product, and improves the product yield.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a waterproof plug demoulding and ejecting device, including a base, a mounting plate is arranged above the base, a plurality of guide columns are fixedly connected between the mounting plate and the base, a cylinder is arranged on the top of the mounting plate, the piston end of the cylinder vertically passes through the mounting plate downward and is fixedly connected to a sliding plate, the sliding plate is slidably connected to the guide column, a demoulding frame is installed at the bottom of the sliding plate, and a plurality of demoulding rods are evenly arranged at the bottom of the demoulding frame; a placing table is fixedly connected to the base, vertically penetrating feeding holes are provided on the placing table and the base, the top of the placing table is inclined, a cavity plate is fixedly connected to the top of the placing table, and the arrangement of the demoulding rods matches the cavity on the cavity plate.

[0005] Optionally, an ejector pin with an arc-shaped structure is arranged at the bottom of the demoulding rod.

[0006] Optionally, a positioning groove is provided on the outer periphery of the top of the placement table, and a positioning hole corresponding to the positioning groove is provided on the cavity plate. When the cavity plate is mounted on the placement table, the positioning pin is inserted into the positioning groove for fixation.

[0007] Optionally, a guide groove is further provided on the periphery of the placement table, and a guide rod matching the guide groove is fixedly connected to the bottom of the demoulding frame.

[0008] Optionally, a cross-structured support frame is fixedly connected in the discharge hole, and a support column for supporting the cavity plate is fixedly connected to the center of the support frame.

[0009] Optionally, handles are fixedly connected to both sides of the cavity plate.

[0010] The water-proof plug demoulding and ejecting device of the present utility model has the following advantages:

[0011] (1) The cavity plate is installed on the placement table in an inclined manner, and there is a height difference between the cavities in each row. When the air cylinder drives the demoulding rod to move downward, the demoulding rod first contacts the product in the higher cavity and ejects and demoulds it. As the demoulding rod continues to descend, the products in the subsequent cavities are gradually ejected and demoulded. The number of products that can be demoulded in one demoulding operation does not change much, but during the demoulding process, the number of products being demoulded simultaneously is greatly reduced, and the power provided by the air cylinder is also greatly reduced, making demoulding easier and reducing the possibility of product damage.

[0012] (2) The ejector pin can act on the edge of the water-proof plug, further reducing the demoulding difficulty and the risk of product damage.

[0013] (3) The guide rod and the guide groove cooperate to improve the docking accuracy between the demoulding rod and the cavity plate. Description of the Drawings

[0018] The following further describes the present utility model with reference to the drawings. In the description of the present utility model, the following description is based on the directions in the Figure 1 drawings.

[0019] As Figures 1 - 4As shown in the figure, a demoulding and ejecting device for a waterproof plug includes a base 1. Above the base 1, there is a mounting plate 2. Four guide columns 3 arranged in a rectangle are fixedly connected between the mounting plate 2 and the base 1. A sliding plate 4 is slidably connected to the guide columns 3. At the top of the mounting plate 2, there is a cylinder 5. The piston end of the cylinder 5 vertically penetrates the mounting plate 2 and is fixedly connected to the top of the sliding plate 4. At the bottom of the sliding plate 4, a demoulding frame 6 is installed. A number of demoulding rods 7 are evenly arranged at the bottom of the demoulding frame 6. At the bottom of the demoulding rod 7, there is a thimble 8 with an arc-shaped structure. The bottom of the thimble 8 is also arc-shaped and will not damage the product. The thimble 8 matches the cavity of the cavity plate 11. When the thimble 8 moves into the cavity, it will fit against the inner wall of the cavity, and the bottom of the thimble 8 presses against the edge of the waterproof plug. Under the action of the cylinder 5, the concentrated pressure is used to demould the waterproof plug, reducing the difficulty of demoulding.

[0020] A placement table 9 is fixedly connected to the base 1. A vertically penetrating blanking hole 10 is opened on the placement table 9 and the base 1. A collection box is placed below the blanking hole 10. The top of the placement table 9 is inclined with the left side higher and the right side lower. A cavity plate 11 is fixedly connected to the top of the placement table 9. The arrangement form of the demoulding rods 7 matches the cavities on the cavity plate 11. A cross-shaped support frame 12 is fixedly connected in the blanking hole 10. A support column 13 for supporting the cavity plate 11 is fixedly connected to the center of the support frame 12. When the cavity plate 11 is installed on the placement table 9, the support column 13 supports at the center position of the cavity plate 11. When the demoulding rods 7 eject the product downward, the support column 13 can ensure the stability of the cavity plate 11, without deformation and without affecting the demoulding operation. A number of positioning grooves 19 are opened on the outer periphery of the top of the placement table 9. Positioning holes corresponding to the positioning grooves 19 are opened on the cavity plate 11. When the cavity plate 11 is installed on the placement table 9, the cavity plate 11 is positioned and fixed by inserting a positioning pin 14 into the positioning groove 19.

[0021] First, install the cavity plate 11 of the mold onto the placement table 9. Both sides of the cavity plate 11 are fixedly connected with handles 15, which facilitate the handling of the cavity plate 11. The cavity plate 11 is in a state of being higher on the left and lower on the right on the placement table 9. Then, manually press the start valve 18, and the air cylinder 5 drives the sliding plate 4 to move downward along the guide post 3, so that the demolding rod 7 also moves downward accordingly. A guide groove 16 is provided on the outer periphery of the placement table 9, and a guide rod 17 is fixedly connected to the bottom of the demolding frame 6. The guide rod 17 cooperates with the guide groove 16 to ensure that the demolding rod 7 can accurately dock with the cavity plate 11. When the demolding rod 7 drives the ejector pin 8 to move downward, the first product to be contacted is the product in the first row of cavities on the left. As the ejector pin 8 continues to move downward, it can eject and demold the product, and the demolded product falls into the collection box. When the demolding operation of the cavities in the first row on the left is completed, the ejector pin 8 will contact the product in the second row of cavities on the left and perform the demolding operation. During the entire downward movement of the demolding rod 7, the products in the cavities will be gradually ejected and demolded from left to right. The number of products that can be demolded in one demolding operation remains unchanged, but during the demolding process, only one row of products is demolded at the same time. In this way, there is no need for the strong power provided by the air cylinder 5, reducing the risk of product damage.

[0022] The embodiments described above are only some of the embodiments of the present utility model, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.
