Abstract
Description
Technical Field
[0001] The present application relates to the technical field of molds, and in particular to an injection mold with a delayed demoulding structure. Background Art
[0002] At present, in the injection molding process, the product is usually demoulded by means of a slanted ejector or a slider. The working principle of the slanted ejector is that during the mold opening, the slanted ejector can eject the product while moving in an oblique direction, so that the product can be demoulded smoothly. The working principle of the slider demoulding is that during the mold opening, the slider can slide perpendicular to or at a certain angle to the mold opening and closing direction, so as to realize the demoulding of the product. When producing automobile fuel tank caps, there are internal undercuts and side concave-convex structures on the automobile fuel tank caps. For the demoulding of such products, the method of using a slanted ejector on a slider is usually adopted. Its working principle is to respectively set a slider and a slanted ejector in the mold, so that during the movement of the slider, the angle of the slanted ejector is used to allow the slider to pass smoothly, thereby achieving the effect of sliding motion.
[0003] Regarding the above-mentioned related technology: the method of ejecting the inclined ejector from the slider, the slider and the inclined ejector are regarded as two independent parts, and are designed and operated separately, which will increase the overall size of the mold and thus increase the production cost of the mold. Utility Model Content
[0004] In order to reduce the production cost of the mold, the present application provides an injection mold with a delayed demoulding structure.
[0005] The present application provides an injection mold with a delayed demoulding structure, which adopts the following technical solutions:
[0006] An injection mold with a delayed demoulding structure, comprising:
[0007] Fixed mold;
[0008] A movable mold, arranged opposite to the fixed mold;
[0009] The demolding assembly includes a slider seat, a slider, a first inclined guide column and a second inclined guide column. The slider seat is slidably arranged on the movable mold. The slider seat is respectively provided with a first guide hole and a slide groove. The slider is slidably inserted in the slide groove. The slider is provided with a second guide hole. The second guide hole is connected to the slide groove. The first inclined guide column and the second inclined guide column are parallel to each other and are respectively inclinedly arranged on the fixed mold. The first inclined guide column is slidably inserted in the first guide hole, and the second inclined guide column is slidably inserted in the second guide hole. The diameter of the first guide hole is larger than the diameter of the first inclined guide column.
[0010] By adopting the above technical solution, when the product needs to be demolded, the fixed mold drives the first inclined guide column and the second inclined guide column to move in the direction away from the movable mold. During this process, since the diameter of the first guide hole is larger than the diameter of the first inclined guide column, the slider seat is delayed in contacting the inner wall of the first guide hole. At the same time, the second inclined guide column applies pressure to the inner wall of the second guide hole to drive the slider to move horizontally, so that the slider gradually moves away from the product inverted position, and at the same time, the product buckle position is separated from the slider. Then, the fixed mold continues to drive the first inclined guide column and the second inclined guide column to move, so that the first inclined guide column applies pressure to the inner wall of the first guide hole to drive the slider seat to move, thereby realizing the demolding of the product. In the utility model, by integrating the slider and the inclined top into a structural design, the specifications and dimensions of the mold are effectively reduced, the processing difficulty is reduced, and the mold cost is effectively reduced.
[0011] Optionally, a guide surface is provided at one end of the slider away from the second oblique guide pillar, the guide surface is inclined in a direction away from the fixed mold, a slider insert is slidably provided on the guide surface, and an internal buckling space is formed between the slider insert and the slider seat;
[0012] A first limiting guide rail is provided on the slider seat, and a first limiting groove is opened on the slider insert. The first limiting guide rail is inserted into the first limiting groove. When the slider moves away from the internal buckling space, the slider insert will sink along with the first limiting guide rail.
[0013] By adopting the above technical solution, when the fixed mold and movable mold are in the mold closing state, an internal snap-fit space is formed between the slider insert and the slider seat, facilitating the internal snap-fit molding of the product. Furthermore, when the fixed mold drives the first and second inclined guide posts to move away from the movable mold, the second inclined guide post drives the slider to move away from the internal snap-fit space, causing the slider insert to move downward along the first limiting guide rail under the action of the guide surface. At this time, the first limiting guide rail limits the slider insert, preventing it from moving with the slider, thereby facilitating the internal snap-fit space to separate from the product and, in turn, facilitating the snap-fit demolding of the product.
[0014] Optionally, a second limiting groove is provided on the slider insert, and a second limiting guide rail is provided on the guide surface. The second limiting guide rail is slidably inserted in the second limiting groove, and the second limiting guide rail is used to prevent the slider insert from separating from the guide surface.
[0015] By adopting the above technical solution, the setting of the second limiting guide rail can, on the one hand, guide the slider insert so that the slider insert can move along a specific track, and on the other hand, limit the slider insert to reduce the possibility of the slider insert detaching from the guide surface.
[0016] Optionally, a receiving groove is provided in the slider seat, the receiving groove is connected to the slide groove, and a positioning component is provided in the receiving groove. When an internal buckling space is formed between the slider insert and the slider seat, the positioning component can limit the movement of the slider.
[0017] By adopting the above technical solution, when the fixed mold and the movable mold are in the clamped state, the positioning assembly can limit the slider, which is beneficial to reduce the possibility of the slider being displaced due to pressure during the injection molding process.
[0018] Optionally, a positioning groove is provided on the slider, and the positioning assembly includes an elastic member and a positioning glass bead, the elastic member is arranged in the receiving groove, the positioning glass bead is slidably inserted in the receiving groove and connected to the elastic member, and the elastic member is used to push the positioning glass bead into the positioning groove.
[0019] By adopting the above technical solution, when the fixed mold and movable mold are in the closed state, the elastic member can push the positioning bead into the positioning groove, thereby facilitating the use of the positioning bead to limit the position of the slider. Furthermore, when the slider moves, the slider can apply pressure to the positioning bead, which in turn applies pressure to the elastic member, driving the elastic member to compress, thereby facilitating the positioning bead to disengage from the positioning groove and move into the receiving groove, so that the positioning bead no longer limits the slider.
[0020] Optionally, the demolding assembly includes a bundle block, which is arranged on the fixed mold and abuts against the movable mold. A first inclined surface is provided on the side of the bundle block close to the movable mold, and a second inclined surface is provided on the slider seat. The first inclined surface is parallel to the second inclined surface, and the bundle block is used to delay the movement of the slider seat.
[0021] By adopting this technical solution, when the fixed mold moves away from the movable mold, it drives the first and second inclined guide posts, as well as the bundle block, to move. During this process, the bundle block interferes with the slider seat, causing the slider seat to move more slowly. Once the bundle block has driven the first inclined surface to a position relative to the second inclined surface, the bundle block no longer constrains the slider seat, allowing the first inclined guide post to drive the slider seat to move, enabling product demolding. This helps improve the stability of the slider seat's delayed movement.
[0022] Optionally, a wear-resistant sheet is provided on the second inclined surface.
[0023] By adopting the above technical solution and setting the wear-resistant sheet, the wear between the bundle block and the slider seat is reduced to a certain extent, which is beneficial to extending the service life of the mold.
[0024] Optionally, a limit block is provided on the outer side wall of the movable mold, and the limit block is used to limit the slider seat.
[0025] By adopting the above technical solution, when the first inclined guide column drives the slider seat to move a certain distance, the limit block can contact the slider seat to stop the slider seat from moving, which is beneficial to ensure the consistency and accuracy of the product during demoulding.
[0026] Optionally, two first guide holes are provided, and the two first guide holes are respectively located on both sides of the slide groove, and the number of the first oblique guide columns is equal to the number of the first guide holes and is provided in a one-to-one correspondence.
[0027] By adopting the above technical solution, the two first inclined guide pillars cooperate with each other to make the slider seat evenly stressed, thereby helping to reduce the possibility of the slider seat shifting due to uneven force during movement, and thus helping to ensure smooth demoulding.
[0028] Optionally, a side concave-convex structure space is provided on the slider seat.
[0029] By adopting the above technical solution, the molding of the side concave-convex structure on the product is facilitated.
[0030] In summary, this application includes at least one of the following beneficial technical effects:
[0031] 1. By integrating the slider and the inclined top into a structural design, the size of the mold is effectively reduced, the processing difficulty is reduced, and thus the mold cost is effectively reduced;
[0032] 2. Through the mutual cooperation of the fixed mold, movable mold, slider seat, slider, first inclined guide post, second inclined guide post, slider insert and first limiting guide rail, when the fixed mold drives the first inclined guide post and the second inclined guide post to move away from the movable mold, the second inclined guide post can drive the slider to move away from the internal buckle space, so that the slider insert moves downward along the first limiting guide rail under the action of the guide surface, thereby facilitating the internal buckle space to separate from the product and further facilitating the buckle demoulding of the product;
[0033] 3. The setting of the bundle block can effectively improve the stability of the delayed movement of the slider seat. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0043] The following is combined with Figure 1-7 This application is described in further detail.
[0044] The embodiments of the present application disclose an injection mold with a delayed demolding structure.
[0045] It should be noted that, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0046] Reference Figure 1 An injection mold with a delayed demoulding structure includes a fixed mold 1, a movable mold 2 and a demoulding assembly 3. The movable mold 2 is arranged opposite to the fixed mold 1, and the demoulding assembly 3 is arranged between the fixed mold 1 and the movable mold 2. The demoulding assembly 3 is used to demould the product.
[0047] Reference Figure 2 A molding cavity 21 is formed between the fixed mold 1 and the movable mold 2. Two pressure strips 22 are fixedly connected to the side of the movable mold 2 close to the fixed mold 1. The two pressure strips 22 are arranged opposite to each other. A connecting block 11 is fixedly connected to the side of the fixed mold 1 close to the movable mold 2. In other embodiments, the connecting block 11 may not be provided.
[0048] Reference Figure 3 and Figure 4 The demoulding assembly 3 includes a slider seat 31, a slider 32, a first inclined guide post 33 (refer to Figure 5 ), the second inclined guide column 34 and the bundle block 35. Among them, the slider seat 31 is respectively connected to the two pressure strips 22 (refer to Figure 2 ) Slide connection.
[0049] Reference Figure 5 The slider seat 31 is provided with two first guide holes 311, each of which is arranged at an angle and parallel to one another. The number of first oblique guide posts 33 is equal to the number of first guide holes 311, and the two first oblique guide posts 33 are parallel to one another and fixedly connected to the connecting block 11. One first oblique guide post 33 is slidably inserted into one first guide hole 311. In this embodiment, the diameter of the first guide hole 311 is larger than the diameter of the first oblique guide post 33.
[0050] Reference Figure 4 and Figure 5 The slider seat 31 defines a slide groove 312, which is located between the two first guide holes 311. The slider 32 is slidably inserted into the slide groove 312. The slider 32 defines a second guide hole 321, which communicates with the slide groove 312. The second oblique guide post 34 is fixedly connected to the connecting block 11 and is parallel to the first oblique guide post 33. The second oblique guide post 34 is slidably inserted into the second guide hole 321.
[0051] When fixed mold 1 (refer to Figure 2 ) When the first and second inclined guide posts 33 and 34 are driven by the connecting block 11 to move away from the movable mold 2, the first guide hole 311 has a larger diameter than the first inclined guide post 33, so that the first inclined guide post 33 applies pressure to the inner wall of the first guide hole 311 with a delay, while the second inclined guide post 34 applies pressure to the inner wall of the second guide hole 321, thereby driving the slider 32 to move away from the molding cavity 21. Next, the fixed mold 1 (refer to Figure 2 ) continues to drive the first oblique guide column 33 and the second oblique guide column 34 to move, so that the first oblique guide column 33 applies pressure to the inner wall of the first guide hole 311 to drive the slider seat 31 to move.
[0052] Reference Figure 6The slider seat 31 is fixedly connected to a first limiting guide rail 313, which is vertically arranged, and one end of the first limiting guide rail 313 is inserted into the slide groove 312. In this embodiment, two first limiting guide rails 313 are provided, and the two first limiting guide rails 313 are arranged opposite to each other.
[0053] Reference Figure 4 and Figure 6 The end of the slider 32 close to the molding cavity 21 is provided with a guide surface 322, which is inclined toward the movable mold 2, and a second position limiting guide rail 323 is fixedly connected to the guide surface 322. In this embodiment, the cross section of the second position limiting guide rail 323 is T-shaped.
[0054] A slider insert 324 is slidably connected to the guide surface 322. The slider insert 324 is provided with a first limiting slot 3241 and a second limiting slot 3242. The number of first limiting slots 3241 is equal to the number of first limiting guide rails 313, and one first limiting guide rail 313 is inserted into one first limiting slot 3241. This facilitates the use of the first limiting guide rail 313 to limit the position of the slider insert 324, preventing the slider insert 324 from moving along with the slider 32.
[0055] The second limiting groove 3242 is adapted to the shape of the second limiting guide rail 323. The second limiting guide rail 323 is slidably inserted into the second limiting groove 3242. Thus, the second limiting guide rail 323 can guide the slider insert 324 so that the slider insert 324 can move along a specific trajectory. At the same time, the second limiting guide rail 323 can limit the slider insert 324 to reduce the possibility of the slider insert 324 escaping from the guide surface 322.
[0056] Reference Figure 4 and Figure 6 An internal snap-fit space 36 is formed between the slider insert 324 and the slider seat 31 to facilitate the internal snap-fit molding of the product. When the slider 32 moves away from the molding cavity 21, the slider insert 324, guided by the guide surface 322, moves downward along the first limiting guide rail 313, thereby opening the internal snap-fit space 36 and separating it from the product, thereby facilitating the product snap-fit demolding.
[0057] Reference Figure 7 In this embodiment, a side concave-convex structure space 37 is provided on the side of the slider seat 31 close to the molding cavity 21 to facilitate the molding of the side concave-convex structure on the product.
[0058] Reference Figure 4The slider 32 has a positioning groove 325, and the slider seat 31 has a receiving groove 314. The receiving groove 314 is connected to the slide groove 312, and a positioning assembly 315 is disposed in the receiving groove 314. The positioning assembly 315 includes an elastic member 3151 and a positioning glass bead 3152. The elastic member 3151 is disposed in the receiving groove 314, and the positioning glass bead 3152 is slidably inserted in the receiving groove 314 and connected to the elastic member 3151. In this embodiment, the elastic member 3151 is a spring.
[0059] Reference Figure 2 and Figure 4 When the fixed mold 1 and the movable mold 2 are in the clamped state, the elastic member 3151 can push the positioning bead 3152 to be inserted into the positioning groove 325, thereby facilitating the use of the positioning bead 3152 to limit the position of the slider 32. Furthermore, when the second inclined guide pillar 34 drives the slider 32 to move, the slider 32 can apply pressure to the positioning bead 3152, causing the positioning bead 3152 to apply pressure to the elastic member 3151, driving the elastic member 3151 to compress, thereby facilitating the positioning bead 3152 to disengage from the positioning groove 325 and move into the receiving groove 314, so that the positioning bead 3152 no longer limits the slider 32.
[0060] Reference Figure 2 The bundle block 35 is fixedly connected to the side of the fixed mold 1 close to the movable mold 2. When the fixed mold 1 and the movable mold 2 are in the mold closing state, the bundle block 35 respectively contacts the movable mold 2 and the slider seat 31, so that the bundle block 35 can limit the slider seat 31 to reduce the possibility of displacement of the slider seat 31 during the injection molding process.
[0061] Reference Figure 4 and Figure 5 The first inclined surface 351 is provided on the side of the bundle block 35 close to the movable mold 2, and the second inclined surface 316 is provided on the slider seat 31. The first inclined surface 351 is parallel to the second inclined surface 316. Figure 2 ) moves away from the movable mold 2, the fixed mold 1 (refer to Figure 2 ) drives the first slanted guide post 33, the second slanted guide post 34, and the bundle block 35 to move. During this process, the bundle block 35 interferes with the slider seat 31, delaying the movement of the slider seat 31. When the bundle block 35 drives the first inclined surface 351 to a position relative to the second inclined surface 316, the bundle block 35 no longer restricts the slider seat 31, allowing the first slanted guide post 33 to drive the slider seat 31 to move, achieving product demolding. This helps improve the stability of the delayed movement of the slider seat 31.
[0062] In this embodiment, a wear-resistant sheet 317 is fixedly connected to the second inclined surface 316 , thereby reducing the wear between the bundle block 35 and the slider seat 31 to a certain extent, thereby facilitating extending the service life of the mold.
[0063] Reference Figure 2 A limit block 23 is fixedly connected to the outer wall of the movable mold 2. When the slider seat 31 moves a certain distance toward the molding cavity 21, the limit block 23 can contact the slider seat 31 to stop the slider seat 31 from moving, which is beneficial to ensure the consistency and accuracy of the product during demolding.
[0064] The injection mold with a delayed demolding structure according to the present embodiment is implemented as follows: When a product needs to be demolded, the fixed mold 1 is first moved away from the movable mold 2. The fixed mold 1 then drives the connecting block 11, the first inclined guide post 33, the second inclined guide post 34, and the bundle block 35 to move. This causes the second inclined guide post 34 to drive the slider 32 away from the molding cavity 21. Simultaneously, the slider insert 324 moves downward along the first limiting guide rail 313 under the action of the guide surface 322, thereby achieving demolding of the internal buckle of the product. This is the initial state, and the slider seat 31 does not move.
[0065] Next, the fixed mold 1 continues to move, causing the first inclined guide post 33 to drive the slider seat 31 away from the molding cavity 21 until it contacts the stop block 23, completing the demolding of the product's concave-convex structure. Finally, the ejector pins eject the product from the molding cavity 21, completing the demolding.
[0066] In the embodiment of the present application, by integrating the slider 32 and the inclined top into an integrated structural design, the specifications and dimensions of the mold are effectively reduced, thereby, on the one hand, reducing the processing difficulty and effectively reducing the mold cost; on the other hand, in the actual production process, the mold in the present application can be suitable for small-tonnage injection molding machines, reducing the cost expenditure in the production process; on the third hand, reducing the wear between the various components of the mold during the production process, effectively reducing the subsequent maintenance costs, and at the same time improving the service life of the mold.
[0067] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
