Description

Technical Field

[0001] This utility model relates to the field of injection mold technology for the production of automotive seals, specifically an injection mold for the production of automotive seals. Background Technology

[0002] Automotive seals are mainly used as sealing components during the assembly of automotive parts. They are mass-produced using injection molds. During production, injection molding machines and molds are used to produce seals of different shapes and sizes for different locations on the vehicle. The use of appropriate molds improves production efficiency. However, due to the softness of the sealing gaskets, quick demolding is not convenient and can easily affect production efficiency.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application CN202222548827.9, application date 2022-09-25) describes an injection mold device for automotive seals. Initially, a second support plate is attached to one of the first support plates. At this time, the injection groove on the first support plate and the injection groove on the second support plate form a ring structure. After connecting the electric injection valve to an external supply pipe and opening the electric injection valve, material can be injected into the injection groove. After the sealing ring is formed, the second support plate is raised, and simultaneously, the push block on the second support plate moves downward and presses against the sealing ring, allowing the sealing ring to completely separate from the second support plate. Finally, the push block can be retracted. Although the prior art can complete ejection and demolding, during operation, it is inconvenient to effectively control the stability of the seal demolding in conjunction with the mold opening state, easily causing adhesion between the seal and the mold, affecting the stability of injection molding.

[0004] To address the aforementioned issues, there is an urgent need for innovative design of injection molds for the production of automotive seals. Utility Model Content

[0005] The purpose of this utility model is to provide an injection mold for the production of automotive seals, so as to solve the problem mentioned in the background art that it is inconvenient to effectively control the stability of the seal demolding in coordination with the mold opening state, which easily causes the seal to stick to the mold and affects the stability of injection molding.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an injection mold for the production of automotive seals, comprising an upper mold for easy injection molding, wherein a lower mold is attached to the lower surface of the upper mold; including: a control rod, rotatably mounted on the front side of the outer surface of the upper mold, and a support seat mounted on the front side of the outer surface of the lower mold, wherein a groove is provided on the right side of the inner surface of the support seat; a small gear is meshed with the lower surface of the control rod, a fixed shaft is mounted on the inner surface of the small gear, and a nesting frame is rotatably connected to the outer surface of the fixed shaft, wherein the nesting frame is provided with a limit movement mechanism; a large gear, mounted on the left side of the outer surface of the fixed shaft, and the large gear is positioned and rotated on the inner surface of the support seat; a rack is meshed with the upper surface of the large gear, and a telescopic rod is mounted on the upper surface of the rack, wherein the telescopic rod is provided with a material feeding spray mechanism.

[0007] Preferably, the control rod and the upper template form a rotating structure, and the lower template and the support base form an integrated structure. The support base and the control rod form a meshing structure through a pinion gear. The pinion gear is embedded in the outer surface of the fixed shaft. At the same time, the fixed shaft and the nested frame form a nested rotating structure, and the pinion gear is located on the inner surface of the nested frame.

[0008] With the above structure, when the control lever is adjusted to follow the upper template, a limit control is formed to prevent the control lever from disengaging from the pinion.

[0009] Preferably, the limiting movement mechanism includes a roller rotatably connected to the upper side of the inner surface of the nested frame, and the lower surface of the roller is attached to the upper surface of the control rod. A slider is installed on the right side of the outer surface of the nested frame, and the slider is limited to slide on the inner surface of the groove.

[0010] With the above structure, the control lever can be effectively adjusted to form a limit movement during use, and with the use of rollers, jamming between the control lever and the nesting frame can be avoided.

[0011] Preferably, the nested frame forms a rotation limiting structure with the control rod via rollers, and the nested frame forms a limiting rotation structure with the support base via sliders and grooves.

[0012] The above structure effectively adjusts the stability of the control lever movement during use and provides limit adjustment for the nesting frame, preventing the nesting frame from detaching.

[0013] Preferably, the large gear is embedded in the outer surface of the fixed shaft, and the large gear and the support base form a positioning and rotating structure, and the large gear and the telescopic rod form a meshing structure through the rack.

[0014] The above structure allows for effective control of the position of the large gear adjusting telescopic rod during use, thereby controlling the stability of subsequent product demolding and demolding material spraying.

[0015] Preferably, the material feeding spraying mechanism includes a limiting component installed on the lower surface of a telescopic rod, which is slidably limited to the upper side of the inner surface of a support base. A cleaning pipe is connected to the upper surface of the telescopic rod, and a through pipe is installed on the rear side of the outer surface of the cleaning pipe. Spray nozzles are installed on the upper and lower sides of the outer surface of the through pipe. A mold release agent pipe is installed on the rear side of the outer surface of the cleaning pipe, and a valve plate is rotatably connected to the inner surface of the mold release agent pipe. A linkage plate is rotatably connected to the lower surface of the valve plate. A connecting rod is rotatably connected to the linkage plate via an offset shaft. A moving rod is rotatably connected to the front side of the outer surface of the connecting rod, and the moving rod is slidably limited to the left side of the inner surface of the telescopic rod. A deflection rod is rotatably connected to the front side of the outer surface of the moving rod, and a turntable is rotatably connected to the front side of the outer surface of the deflection rod via an offset shaft. The turntable shaft is rotatably connected to the left side of the outer surface of the telescopic rod.

[0016] The above structure allows for the effective assembly of the cleaning tube and the release agent tube during use, thereby controlling the opening and closing of the release agent tube and adjusting its stability during use.

[0017] Preferably, the telescopic rod forms a limiting sliding structure with the support seat through the limiting member, and the telescopic rod and the cleaning pipe form a supporting structure. The cleaning pipe, the through pipe, the nozzle and the release agent pipe form an integrated structure. At the same time, the release agent pipe forms a central rotation structure with the linkage plate through the shaft and the valve plate. The linkage plate forms an angle deflection structure with the moving rod through the connecting rod. The moving rod forms a circumferential linear movement structure with the turntable through the deflection rod.

[0018] With the above structure, it is easy to use the cleaning tube to assist in demolding during demolding, and the cooperation between the tube and the mold release agent allows for the spraying of mold release agent material after demolding, increasing the convenience of subsequent demolding.

This mechanism, along with the rollers inside the nesting frame, prevents jamming between the control rod and the nesting frame. It also ensures that the large gear, driven by the pinion, rotates coaxially with the fixed shaft assembly to adjust the position of the telescopic rod. Furthermore, the slider assembled in the nesting frame cooperates with the sliding groove on the support base to control the limited sliding of the nesting frame, improving the stability of the nesting frame adjustment.

[0022] 3. This injection mold for automotive sealing parts production is equipped with a material feeding spray mechanism, which facilitates effective control of the position of the telescopic rod. The position of the cleaning pipe and the mold release agent pipe can be adjusted by the telescopic rod, thereby adjusting the position of the spray nozzle.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-6The present invention provides the following technical solution: an injection mold for the production of automotive sealing parts, wherein an upper template 1 is provided for easy injection production, and a lower template 2 is attached to the lower surface of the upper template 1.

[0032] Example 1: As Figures 1-3 The technical solution shown is provided by this utility model as follows: An injection mold for the production of automotive seals, comprising: a control rod 3, rotatably positioned on the front side of the outer surface of the upper mold plate 1, and a support base 4 mounted on the front side of the outer surface of the lower mold plate 2, wherein a groove 5 is provided on the right side of the inner surface of the support base 4; a pinion 6 is meshed with the lower surface of the control rod 3, and a fixed shaft 7 is mounted on the inner surface of the pinion 6; a nesting frame 8 is rotatably connected to the outer surface of the fixed shaft 7, and the nesting frame 8 is provided with a limit movement mechanism; the control rod 3 and the upper mold plate 1 form a rotating structure, and the lower mold plate 2 and the support base 4 form an integrated structure, wherein the support base 4... 4. A small gear 6 and a control lever 3 form a meshing structure, and the small gear 6 is embedded in the outer surface of the fixed shaft 7. At the same time, the fixed shaft 7 and the nested frame 8 form a nested rotation structure, and the small gear 6 is located on the inner surface of the nested frame 8. The limiting movement mechanism includes a roller 9 rotatably connected to the upper side of the inner surface of the nested frame 8, and the lower surface of the roller 9 is in contact with the upper surface of the control lever 3. A slider 10 is installed on the right side of the outer surface of the nested frame 8, and the slider 10 is limited to slide on the inner surface of the slide groove 5. The nested frame 8 forms a rotation limiting structure with the control lever 3 through the roller 9, and the nested frame 8 forms a limiting rotation structure with the support base 4 through the slider 10 and the slide groove 5.

[0033] In use, injection molding is performed between the upper mold plate 1 and the lower mold plate 2 to produce automotive seals. When the mold separates between the upper mold plate 1 and the lower mold plate 2, the movement of the lower mold plate 2 controls the synchronous movement of the support base 4. The small gear 6 on the support base 4 meshes with the control rod 3, causing the control rod 3 to rotate with the upper mold plate 1. The meshing and rotation of the small gear 6 drives the large gear 11 mounted on the fixed shaft 7 to rotate coaxially within the support base 4, and causes the large gear 11 to adjust the position of the telescopic rod 13. When the control rod 3 and the small gear 6 mesh, the nested frame 8, which is rotatably connected to the fixed shaft 7, and the rollers 9 nested in the nested frame 8 limit the movement of the control rod 3, controlling the stability of the movement of the control rod 3 and preventing the control rod 3 from jamming. The slider 10 assembled in the nested frame 8 is stably fixed in the groove 5 opened in the support base 4 to form a limited rotation, improving the stability of the angle control formed by the nested frame 8 and the control rod 3.

[0034] Example 2: Figures 1-4The technical solution shown, based on Embodiment 1, further discloses the movement control of the telescopic rod 13, the specific contents of which are as follows: a large gear 11 is installed on the left side of the outer surface of the fixed shaft 7, and the large gear 11 is positioned and rotated on the inner surface of the support base 4. A rack 12 is meshed on the upper surface of the large gear 11, and a telescopic rod 13 is installed on the upper surface of the rack 12. At the same time, the telescopic rod 13 is provided with a material discharge spraying mechanism. The large gear 11 is embedded in the outer surface of the fixed shaft 7, and the large gear 11 and the support base 4 form a positioning and rotation structure. The large gear 11 and the telescopic rod 13 form a meshing structure through the rack 12.

[0035] When the control lever 3 adjusts the small gear 6 to control the rotation of the large gear 11, the rack 12 connected to the large gear 11 will drive the telescopic rod 13 installed on the rack 12 to move. The ratio of the small gear 6 and the large gear 11 improves the movement stability of the telescopic rod 13. In conjunction with the limiting component 14 installed on the telescopic rod 13, the telescopic rod 13 is stably limited and slides in the support seat 4, thus improving the movement stability of the telescopic rod 13.

[0036] Example 3: Figure 1 , Figure 2 , Figure 5 and Figure 6 The technical solution shown, based on Embodiment 2, further discloses the demolding of the cleaning pipe 15 assembled with the telescopic rod 13, and the spraying of the demolding agent material by the assembled demolding agent pipe 18. The specific details are as follows: The material feeding spraying mechanism includes a limiting member 14 installed on the lower surface of the telescopic rod 13, which slides on the upper side of the inner surface of the support base 4. The upper surface of the telescopic rod 13 is connected to the cleaning pipe 15, and a through pipe 16 is installed on the rear side of the outer surface of the cleaning pipe 15. Spray nozzles 17 are installed on the upper and lower sides of the outer surface of the through pipe 16. The demolding agent pipe 18 is installed on the rear side of the outer surface of the cleaning pipe 15, and a valve plate 19 is rotatably connected to the inner surface of the demolding agent pipe 18. A linkage disc 20 is rotatably connected to the lower surface of the valve plate 19, and the linkage disc 20 is rotatably connected to a connecting rod 21 via an off-axis. The front side of the outer surface of the connecting rod 21 rotates... A movable rod 22 is provided, which is limited and slidably positioned on the left side of the inner surface of the telescopic rod 13. A deflecting rod 23 is rotatably connected to the front side of the outer surface of the movable rod 22. A turntable 24 is rotatably connected to the front side of the outer surface of the deflecting rod 23 via a deflection axis. The turntable 24 is rotatably connected to the left side of the outer surface of the telescopic rod 13. The telescopic rod 13 forms a limiting sliding structure with the support base 4 via the limiting member 14. The telescopic rod 13 forms a support structure with the cleaning pipe 15. The cleaning pipe 15 forms an integrated structure with the through pipe 16, the nozzle 17, and the release agent pipe 18. At the same time, the release agent pipe 18 forms a central rotation structure with the linkage plate 20 via the shaft and the valve plate 19. The linkage plate 20 forms an angle deflection structure with the movable rod 22 via the connecting rod 21. The movable rod 22 forms a circumferential linear movement structure with the turntable 24 via the deflecting rod 23.

[0037] When the telescopic rod 13 moves, it drives the nozzle 17 assembled on the cleaning pipe 16 installed on the cleaning pipe 15 to assist in demolding the product between the upper template 1 and the lower template 2, and cleans impurities and particles on the core and cavity. After demolding, the motor on the lower side of the turntable 24 is started to effectively control the rotation of the turntable 24. The deflection shaft on the turntable 24 drives the deflection rod 23 to rotate and the moving rod 22 connected to it to form a circumferential linear movement structure. The connecting rod 21 assembled by the rotation of the moving rod 22 and the linkage plate 20 assembled by the deflection shaft at the other end of the connecting rod 21 form angle control. Thus, the valve plate 19 is driven to open and close through the central axis of the linkage plate 20, and the material in the release agent pipe 18 is carried by the continuous blowing of the cleaning pipe 15 to spray the release agent material onto the core and cavity, improving the convenience of subsequent demolding.
