[0028] 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.

[0029] like Figures 1 to 7The present invention discloses a sliding block with a slanted ejector demolding structure, including a movable template 5, an slanted ejector seat 1 installed on the upper part of the movable template 5, a slanted ejector 2 installed on the slanted ejector seat 1, the top of the slanted ejector 2 being slidably connected to the slanted ejector seat 1 from left to right, a slider 3 connected to the middle part of the slanted ejector 2, a slanted guide post 4 connected to the slider 3, a core 8 installed on the lower part of the movable template 5, a hook extending to the right at the bottom of the slanted ejector 2, and a groove corresponding to the hook at the top of the core 8. The top of the inclined ejector 2 is slidably connected to the inclined ejector seat 1. A slider 3 is connected to the middle of the inclined ejector 2, and an inclined guide post 4 is connected to the slider 3. The bottom of the inclined ejector 2 is provided with a hook extending to the right, and the top of the core 8 is provided with a groove corresponding to the hook. This simplifies the mold structure, makes installation and operation easy. The upper side of the product has both longitudinal and transverse undercuts, which can realize core pulling in two directions. The longitudinal undercut is pulled using the slider 3, while the transverse undercut is pulled using the inclined ejector 2. When the mold opens, the inclined guide post 4, which is fixed on the front mold, is... The slider moves along with the front mold, causing the slider 3 mounted on the moving platen 5 to move upward. Due to the movement of the slider 3, the inclined ejector 2 mounted on the inclined ejector seat 1 moves to the left, thereby pulling out the product snap-in. Finally, the product is ejected by the ejector pin. When the mold is closed, the inclined guide post 4 first inserts into the inclined guide post hole of the slider 3, causing the slider 3 to reset, and then causing the inclined ejector 2 to reset. Since the slider 3 is the driving part and has a large weight, while the inclined ejector 2 is the driven part, the smoothness and reliability of the mechanism movement are ensured, the mold manufacturing cycle and production cost are reduced, and the later maintenance is easy.

[0030] As a specific implementation, the top of the inclined top 2 is T-shaped, and the inclined top seat 1 is provided with a T-shaped groove for connecting the top of the inclined top 2, so that the top of the inclined top 2 is more stably installed, effectively preventing it from falling out, and the top of the inclined top 2 slides more stably from left to right.

[0031] The slider 3 is equipped with an inclined guide block 9 for sliding connection of the inclined top 2. The inclined guide block 9 is provided with a guide groove for sliding connection of the inclined top 2 and the slider 3, so that the sliding connection between the inclined top 2 and the slider 3 is smoother and more stable, and the movement of the inclined top 2 and the slider 3 is more stable.

[0032] The moving template 5 is equipped with a guide block 10 for sliding connection of the inclined top guide block 9. The guide block 10 is provided with a sliding groove for the inclined top guide block 9 to be installed, so that the inclined top guide block 9 slides more stably.

[0033] The slider 3 is provided with a guide post hole for connecting the guide post 4, which facilitates the sliding connection between the guide post 4 and the slider 3 and makes it easier for the guide post 4 to drive the slider 3 to move.

[0034] The right side of the moving template 5 is equipped with a slanted guide auxiliary device 6 that holds the slider 3 in place. The function of the slanted guide auxiliary device 6 is to improve the guiding accuracy of the slider 3 and avoid the breakage of the slanted guide post 4 due to insufficient accuracy.

[0035] The left and right sides of the sliding block 3 are provided with sliding block guide blocks 7, so that the sliding block 3 slides up and down more stably.

[0036] The inclined top seat 1, the inclined top guide block 9 and the guide block 10 are all provided with screw mounting holes, so that the inclined top seat 1, the inclined top guide block 9 and the guide block 10 are conveniently fixed and installed by screws, and the installation is quick and stable.

[0037] Working principle:

[0038] 1. The inclined top seat 1 is fixed on the movable die plate 5.

[0039] 2. In the mold opening process, the inclined guide pillar 4 provides power to directly drive the sliding block 3 to move.

[0040] 3. The core pulling action is performed by the sliding block 3 and the inclined top 2 simultaneously, and the action is performed in linkage.

[0041] 4. The core pulling action is completely completed according to the opening and closing action of the mold, and the linkage core pulling effect is achieved.

[0042] 5. The bottom of the inclined top 2 is T-shaped, which cooperates with the T-shaped groove of the inclined top seat 1 to realize left and right movement and complete horizontal core pulling.

[0043] 6. In the application of complex products, the mold core pulling structure can be greatly simplified.

[0044] 7. The structure has certain adaptability. When using the structure, there should be no product glue below the inclined top 2 after the core pulling is completed, otherwise the glue will interfere with the inclined top 2 during the ejection process.

[0045] 8. The sliding block 3 is guided by the guide block 7 installed on the movable die plate.

[0046] 9. The function of the inclined guide auxiliary device 6 is to improve the guiding accuracy of the sliding block 3 and avoid the fracture phenomenon caused by insufficient accuracy of the inclined guide pillar.

[0047] 10. The installation device has low investment cost, low cost and reliable application.

[0048] 11. The structure of the whole sliding block 3 with the inclined top 2 produces less line clamping than the separate design of multiple section sliding blocks.

[0049] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
