Description

Technical Field

[0001] The utility model relates to the technical field of injection mold sliders, in particular to a slider assembly of an injection mold. Background Art

[0002] Injection mold is a tool for producing plastic products; injection molding is also called injection molding. It is a molding method that combines injection and molding. Injection molding can realize automation of operation, selection of patterns and varieties, shapes from simple to complex, sizes from large to small, and precise product size. The product is easy to update and can be made into complex-shaped parts. Injection molding is suitable for mass production and molding processing fields such as complex-shaped products.

[0003] Sliders are mostly used in the production of injection molded products to facilitate demoulding of injection molded products. However, the slider structure of most molds on the market is relatively simple and lacks a positioning structure. During demoulding or compression molding, the sliding direction of the slider may be offset, affecting the production efficiency of the product.

[0004] For example, a slider structure of an injection mold disclosed in Chinese patent publication number CN216423354U can limit the sliding trajectory of the slider through the cooperation of a slide groove, a slide plate, a positioning plate, a positioning hole and a slide rod, thereby preventing the sliding direction of the slider from shifting. Through the cooperation of the oil inlet, the oil cavity and the oil outlet hole, the lubricating oil can overflow from the oil outlet hole to the outer surface of the inclined guide column and the outer surface of the guide column groove, thereby preventing the inclined guide column from being forcibly pulled out when it is stuck in the guide column groove and causing damage to the equipment, thereby improving the service life of the equipment.

[0005] The inclined guide post of the above-mentioned slider structure is inserted into the guide post groove, and there is a certain friction between the inclined guide post and the guide post groove. Therefore, the above-mentioned structure is provided with a corresponding oil outlet assembly to reduce the friction force. However, the lubricating oil flowing down the oil chamber can only adhere to one side of the guide post groove, resulting in that the other side of the inclined guide post and the guide post groove do not adhere to the lubricating oil. Therefore, the friction force can easily cause the inclined guide post to be stuck in the guide post groove or the inclined guide post to damage the half end face of the guide post groove. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides a slider assembly for an injection mold, which solves the problems raised in the above background technology.

[0007] To achieve the above purpose, the utility model is implemented by the following technical solutions: a slider assembly of an injection mold, comprising an injection molding base, a slider assembly is arranged on the injection molding base, and a top plate is arranged above the injection molding base, a guide assembly is arranged on the top plate, the slider assembly is movably mounted on the injection molding base, and the top plate is connected to the injection molding base through a hydraulic cylinder installed on the injection molding base;

[0008] The guide assembly includes an extension plate installed at the bottom of the top plate, an abutment plate is provided at the vertical corner where the extension plate and the top plate are connected, an abutment groove is provided on the abutment plate, a mounting piece is provided on the abutment groove, the mounting piece is tilted and an inclined guide column for sliding the slider assembly is provided at the bottom, an oil chamber column installed in the top plate is provided above the guide column, and an addition port for infusion is provided on the top of the oil chamber column.

[0009] The difference between the present invention and the prior art in adding lubricating oil to the guide column in this embodiment is that the guide column is used as a solid column, and the oil chamber originally arranged inside is placed on the top. When the lubricating oil is dripped on the oil chamber column, because the guide column is a cylinder and is placed at an angle, the lubricating oil will infiltrate the entire guide column during the sliding process, thereby greatly reducing the friction between the guide column and the groove, avoiding the guide column from getting stuck, and ensuring the normal progress of injection molding.

[0010] A further improvement of the technical solution of the utility model is that: the extension plate is fixedly connected to the top plate, the abutment plate is limitedly installed on the extension plate, and the abutment plate is limitedly abutted with the mounting plate through the abutment groove, the mounting plate is welded to the guide column, and the oil chamber column passes through the top plate to just above the guide column.

[0011] The further improvement of the technical solution of the utility model is that: the slider assembly includes a guide column groove opened in the middle of the injection molding base, the left and right ends of the guide column groove are provided with sliders connected by connecting plates, the middle of the slider is provided with a through groove, and the front and rear ends of the guide column groove are symmetrically distributed with sealing plates connected by connecting pieces. Preferably, the guide column groove serves as a groove body for loading the guide column, and the through groove provided in the middle of the slider serves as a channel for wrapping the guide column. This has the advantage that the lubricating oil will not be stored in the slider during the dripping process compared to the prior art, but will accumulate in the through groove, and the oil can be quickly cleaned by removing the sealing plate.

[0012] A further improvement of the technical solution of the utility model is that the cut surface of one end of the slider close to the extension plate is an inclined surface, and a bonding layer that is bonded to the inclined surface of the abutment plate is provided at the inclined surface. Preferably, the technical solution adopted by the utility model for the stability and guidance of the sliding of the slider is to gradually bond the inclined surface of the abutment plate with the inclined surface of one end of the slider, and to guide the moving position of the slider in the longitudinal direction in cooperation with the guide column.

[0013] The further improvement of the technical solution of the utility model is that: the injection molding base is provided with a mounting vertical plate, the side of the mounting vertical plate close to the slider is provided with a positioning plate for positioning, the positioning plate is provided with plugs corresponding to the positioning holes on the side of the slider, and the number of the plugs matches the number of the positioning holes on the side of the slider. In the above, after the slider is guided in the longitudinal position, the positioning hole assembly of the slider fits with the plug during the horizontal movement, so the positioning plate guides the slider horizontally to avoid the deviation of the slider.

[0014] A further improvement of the technical solution of the utility model is that a vertical plate is arranged at one end of the sliding block away from the guide column, a traction rod is arranged on the vertical plate, a return spring is sleeved between the traction rod and the vertical plate, a left mold sliding on the injection molding base is arranged at one end of the traction rod, and a right mold is arranged on one side of the left mold.

[0015] Beneficial Effects

[0016] The utility model provides a slider assembly for an injection mold. Compared with the prior art, it has the following advantages:

[0017] Beneficial effects:

[0018] 1. The slider assembly of the injection mold uses the guide column as a solid column through the guide assembly, and places the oil chamber originally set inside on the top. When the oil chamber column drips lubricating oil, because the guide column is a cylinder and is placed at an angle, the lubricating oil will infiltrate the entire guide column during the sliding process, thereby greatly reducing the friction between the guide column and the groove, avoiding the guide column from getting stuck, and ensuring the normal progress of injection molding.

[0019] 2. The slider assembly of the injection mold uses the guide column groove as the groove body for loading the guide column through the slider assembly, and the through groove arranged in the middle of the slider serves as a channel for wrapping the guide column. Therefore, compared with the prior art, the lubricating oil will not be stored in the slider during the dripping process, but will accumulate in the through groove. The oil can be quickly cleaned by removing the sealing plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides three technical solutions:

[0027] Figure 1-3 The first embodiment is shown: a slider assembly of an injection mold, comprising an injection molding base 1, a slider assembly is arranged on the injection molding base 1, and a top plate 2 is arranged above the injection molding base 1, a guide assembly is arranged on the top plate 2, the slider assembly is movably mounted on the injection molding base 1, and the top plate 2 is connected to the injection molding base 1 through a hydraulic cylinder 3 installed on the injection molding base 1;

[0028] The guide assembly includes an extension plate 401 installed at the bottom of the top plate 2, an abutment plate 402 is provided at the vertical corner where the extension plate 401 and the top plate 2 are connected, an abutment groove 403 is provided on the abutment plate 402, a mounting piece 407 is provided on the abutment groove 403, the mounting piece 407 is tilted and an inclined guide column 404 for sliding the slider assembly is provided at the bottom, an oil chamber column 405 installed in the top plate 2 is provided above the guide column 404, and an addition port 406 for injection is provided on the top of the oil chamber column 405.

[0029] The difference between the present invention and the prior art in adding lubricating oil to the guide column 404 in this embodiment is that the guide column 404 is used as a solid column, and the oil chamber originally set inside is placed on the top. When the oil chamber column 405 drips the lubricating oil, because the guide column 404 is a cylinder and is placed at an angle, the lubricating oil will infiltrate the entire guide column 404 during the sliding process, thereby greatly reducing the friction generated by the guide column 404 and the groove, avoiding the guide column 404 from getting stuck, and ensuring the normal progress of injection molding.

[0030] The extension plate 401 is fixedly connected to the top plate 2, the abutment plate 402 is limitedly installed on the extension plate 401, and the abutment plate 402 is limitedly abutted with the mounting plate 407 through the abutment groove 403, the mounting plate 407 is welded to the guide column 404, and the oil chamber column 405 passes through the top plate 2 to just above the guide column 404.

[0031] Figure 2-4 The second embodiment is shown, and the main difference from the first embodiment is that the slider assembly includes a guide column groove 501 opened in the middle of the injection molding base 1, and sliders 503 connected by connecting plates 502 are arranged at the left and right ends of the guide column groove 501, and a through groove 504 is arranged in the middle of the slider 503, and sealing plates 506 connected by connecting members 505 are symmetrically distributed at the front and rear ends of the guide column groove 501. Preferably, the guide column groove 501 serves as a groove body for loading the guide column 404, and the through groove 504 arranged in the middle of the slider 503 serves as a channel for wrapping the guide column 404. This has the advantage that the lubricating oil will not be stored in the slider 503 during the dripping process compared with the prior art, but will be accumulated in the through groove 504, and the oil can be quickly cleaned by removing the sealing plate 506.

[0032] The end section of the slider 503 close to the extension plate 401 is an inclined surface, and a bonding layer 507 is provided at the inclined surface to be bonded with the inclined surface of the abutment plate 402. Preferably, the technical solution adopted by the utility model for the stability and guidance of the sliding of the slider 503 is to gradually bond the inclined surface of the abutment plate 402 with the inclined surface of one end of the slider 503, and cooperate with the guide column 404 in the longitudinal direction to guide the moving position of the slider 503.

[0033] Figure 1 and Figure 3 The third embodiment is shown, which is mainly different from the first embodiment in that: the injection molding base 1 is provided with a mounting vertical plate 508, and a positioning plate 509 for positioning is provided on a side of the mounting vertical plate 508 close to the slider 503, and the positioning plate 509 is provided with plug blocks 510 corresponding to the side positioning openings of the slider 503, and the number of the plug blocks 510 matches the number of the side positioning openings of the slider 503. In the above, after the slider 503 is guided in the longitudinal position, the positioning opening assembly of the slider 503 fits with the plug blocks 510 during the horizontal movement, so the positioning plate 509 guides the slider 503 horizontally to prevent the slider from deviating.

[0034] A vertical plate 511 is provided at one end of the slider 503 away from the guide column 404, a traction rod 512 is provided on the vertical plate 511, a return spring 513 is sleeved between the traction rod 512 and the vertical plate 511, a left mold 514 is provided at one end of the traction rod 512 to slide on the injection molding base 1, and a right mold 515 is provided on one side of the left mold 514.

[0035] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0036] When in use, the hydraulic cylinder 3 is started to lower the top plate 2. It should be noted that after the top plate 2 is lowered to a certain height, when the guide column 404 is not completely inserted into the through groove 503, lubricating oil is added from the addition port 406 at this time, and the oil falls along the oil chamber column 405 to the surface of the guide column 404. Due to the curved surface of the guide column 404, the oil fully adheres to the guide column 404, and then the falling oil enters the guide column groove 501 through the through groove 504 and accumulates. At this time, the hydraulic cylinder 3 continues to start, and the guide column 404 is gradually inserted into the guide column groove 501 through the through groove 504. In this process, the slider 503 slides to the left until the insert block 510 is inserted into the positioning plate 509 and the bonding layer 507 is bonded to the abutment plate 402, and finally the return spring 513 is pulled. When the product is molded here, the top plate 2 rises, and under the action of the elastic force of the return spring 513, the left mold 514 is nested into the right mold 515 to complete the re-molding of the product.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
