Description

Composite slider mechanism

[0001] This application claims priority to Chinese Patent Application No. 202410970598.0, filed on July 19, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of die-casting mold technology, such as a composite slider mechanism. Background Technology

[0003] As shown in Figures 1-2, product 20 has an inner structure 30. During the molding process, the stroke of the slider insert exiting the inner structure 30 is relatively long, and it is necessary to use a hydraulic cylinder to pull it out. However, during the production of product 20, due to high temperature, high pressure, and excessive clamping force of the slider insert, the slider insert exits unstably and may get stuck, thus affecting the yield of product 20 molding. Summary of the Invention

[0004] This application provides a composite slider mechanism to solve the problem that excessive clamping force of the slider insert leads to unstable slider insert retraction, resulting in jamming and affecting the yield of product molding. Therefore, this application aims to solve the above-mentioned problems.

[0005] This application provides a composite slider mechanism, which is disposed within a female template and a male template, including:

[0006] A pressing component, which is fixedly connected inside the mother template;

[0007] A sliding member is slidably disposed within the male template. The sliding member has an oblique hole. A slider insert is fixedly connected to the side of the sliding member near the product. When the pressing member acts on the oblique hole of the sliding member, the sliding member drives the slider insert to move a first stroke.

[0008] A driving component, the moving end of which is fixedly connected to the end of the slider away from the slider insert, is configured to control and drive the slider to move a second time after the first movement is completed, so that the slider insert completely exits the inner structure of the product.

[0019] The following description is based on embodiments of this application and their accompanying drawings.

[0020] This application provides a composite slider mechanism, including:

[0021] The mother template 100 has a pressing member 103 and a slider bundle 101 fixedly connected inside it. The slider bundle 101 has a first inclined surface 102 on the side near the product 20.

[0022] A template 200 is provided, and a slider plate 210 is fixedly connected inside the template 200. The slider plate 210 is located at the end of the slider 220 that exits from the product 20. A groove 211 is provided on the side of the slider plate 210 that contacts the slider 220.

[0023] A sliding member 220 is slidably disposed within the male template 200. The sliding member 220 has an oblique hole 250. A slider insert 221 is fixedly connected to the side of the sliding member 220 closest to the product 20. When the pressing member 103 acts on the oblique hole 250 of the sliding member 220, the sliding member 220 drives the slider insert 221 to move a first stroke. The end of the sliding member 220 furthest from the product 20 has a second oblique surface 222 and a connecting groove 223. The second oblique surface 222 engages with the first oblique surface 102 of the slider block 101 after the mold is closed. 1. The sliding member 220 is pressed against the slider insert 221 to prevent the slider insert 221 from retracting under the action of the mold injection pressure. The side of the sliding member 220 that contacts the slider pressure plate 210 is provided with a slide table 224. The slide table 224 is slidably connected in the slide groove 211 of the slider pressure plate 210. The sliding member 220 plays a guiding role when it moves. The end of the slider pressure plate 210 away from the product 20 is fixedly connected with a fixing frame 225. The side of the fixing frame 225 away from the sliding member 220 is provided with a limiting end 226, which is set to limit the displacement of the moving end 231 of the driving member 230.

[0024] The driving component 230 is fixedly connected to the fixed frame 225. The moving end 231 of the driving component 230 is fixedly connected to the connecting component 232. The side of the connecting component 232 away from the moving end 231 is fixedly connected to the connecting groove 223 of the slider 220. It is configured to control the connection with the slider 220 and drive the slider 220. After the first stroke is completed, it drives the slider insert 221 fixedly connected to it to move to the second stroke, so that it completely exits the inner structure 30 of the product 20.

[0025] A fixing member 240 is assembled on the side of the slider pressure plate 210 near the slider 220. In this embodiment, the fixing member 240 includes, but is not limited to, a screw. A positioning member 228 is provided on the side of the fixing member 240 near the slider 220. In this embodiment, the positioning member 228 includes, but is not limited to, a positioning steel column. A positioning hole 227 is provided on the side of the slider 220 near the slider pressure plate 210, and an elastic member 229 is provided on the side of the slider 220 near the slider insert 221. In this embodiment, the elastic member 229 includes, but is not limited to, a spring. When the mold is opened or closed, the positioning member 228 cooperates with the positioning hole 227 under the action of the elastic member 229, thereby pressing against the slider 220 and preventing the slider insert 221, which is fixedly connected to it, from falling down due to gravity.

[0026] The working process of this application is as follows: When the mold opens, the pressing member 103 acts on the inclined hole 250 of the sliding member 220, causing the sliding member 220 to drive the slider insert 221 to move for the first stroke. The slider insert 221 exits the inner structure 30 of the product 20 for the first time until the pressing member 103 stops acting on the inclined hole 250 of the sliding member 220, and the slider insert 221 stops moving. At this time, under the action of the elastic member 229, the positioning member 228 cooperates with the positioning hole 227, thereby pressing against the sliding member 220 and preventing the slider insert 221, which is fixedly connected to it, from falling down due to gravity. Subsequently, the connecting member 232 of the moving end 231 of the driving member 230 passes through the connecting groove 2. 23 drives the sliding member 220 to move to the limiting end 226 of the fixed frame 225, so that the sliding member 220 drives the slider insert 221 to move for the second stroke, and the slider insert 221 completely exits the inner structure 30 of the product 20 for the second time; when the mold is closed, the connecting member 232 of the moving end 231 of the drive member 230 first pushes the sliding member 220 to move through the connecting groove 223, so that the sliding member 220 drives the slider insert 221 to reset for the second stroke. Then, when the mold is closed, the pressing member 103 acts on the inclined hole 250 of the sliding member 220, so that the sliding member 220 drives the slider insert 221 to reset for the first stroke, until the mold is closed and the slider insert 221 is completely reset.

[0027] This application discloses a composite slider mechanism in which a slider 220 is connected to the side of the driving member 230 near the slider insert 221. When the mold opens, the slider 220, under the action of the pressing member 103, first drives the slider insert 221 to move a first stroke, so that the slider insert 221 stably exits the inner structure 30 of the product 20 for the first time. Then, under the action of the driving member 230, the slider 220 drives the slider insert 221 to move a second stroke, so that the slider insert 221 completely exits the inner structure 30 of the product 20 for the second time. This composite slider mechanism effectively solves the problem of unstable exit of the slider insert 221 and the phenomenon of jamming, thereby improving the production efficiency and production quality of the product 20.

[0028] It should be noted that this application is not limited to the above-described embodiments. Any simple modifications, equivalent changes and alterations made by those skilled in the art to the above embodiments based on the technical solutions of this application shall fall within the protection scope of this application.
