A groove is arranged on the upper surface of the movable mold, and the lower end of the first inclined ejector can slide up and down in the groove. This patent provides an inclined ejector mechanism for a mold that can be smoothly demolded and has high reliability.

[0003] However, for some common parts such as the rear lamp body of an automobile, its appearance is small, but there are many screw structures for fixing the plastic part to the vehicle body, resulting in more inclined ejector structures on the back mold. And the inclined ejector occupies a large space in the mold, resulting in no space for designing the straight ejector block structure for ejecting the product. Content of the Utility Model

[0004] The purpose of the utility model is to provide a combined structure in which a straight ejector drives an inclined ejector to slide, solving the problem that the inclined ejector occupies a large space in the mold, resulting in no space for designing the straight ejector block structure for ejecting the product.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A combined structure in which a straight ejector drives an inclined ejector to slide, including a movable template and an ejector plate. A plastic part is arranged inside the movable template. A backing plate is installed on the right side of the movable template through bolts. An inclined ejector block is slidably connected inside the movable template. A straight ejector block is installed inside the ejector plate through bolts. The straight ejector block penetrates through the backing plate and the movable template and is slidably connected to both the backing plate and the movable template. The straight ejector block is slidably connected to the inclined ejector block.

[0006] Preferably, a slider is fixedly connected to the side of the straight ejector block close to the inclined ejector block. A chute is opened on the side of the inclined ejector block close to the straight ejector block, and the slider is slidably connected to the inside of the chute. Through the setting of the slider, when the straight ejector block moves, the inclined ejector block can be subjected to a force in the parallel direction of the slider.

[0007] Preferably, a hollow shell is fixedly connected inside the backing plate, and the hollow shell is slidably connected to the straight ejector block. A sliding plate and a sponge block are slidably connected inside the hollow shell, and the sliding plate and the sponge block are in contact with each other. An oil drain hole is formed in one side of the hollow shell close to the straight ejector block. A top pin is fixedly connected to the side of the sliding plate away from the sponge block. The top pin penetrates through the hollow shell and is slidably connected to the hollow shell. A baffle is fixedly connected to the outer side of the straight ejector block, and the baffle abuts against the top pin. The reaction force is applied to the top pin through the baffle, thereby squeezing the sponge block inside the sliding plate.

[0008] Preferably, a spring is sleeved on the outer side of the pin body of the top pin. One end of the spring is fixedly connected to the sliding plate, and the other end of the spring is fixedly connected to the inner surface of the hollow shell. Through the arrangement of the spring, elastic force can be applied to the sliding plate.

[0009] Preferably, two through holes are formed inside the sliding plate. Through the arrangement of the through holes, it is convenient for the lubricating oil to leak out through the sliding plate.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. By arranging the straight ejector block in the present utility model, the straight ejector block is hung on the inclined ejector block through the slider, and at the same time, the straight ejector block is fixed on the ejector pin plate through bolts. In this way, when the ejector pin plate moves upward to make the ejector block move forward, the inclined ejector moves through the guiding slider and finally disengages from the plastic part, achieving the purpose that the straight ejector block has sufficient moving space.

[0012] 2. By arranging a hollow shell inside the backing plate in the present utility model, the lubricating oil is stored in the sponge block inside the hollow shell. When the straight ejector block follows the relative displacement between the ejector pin plate and the moving template, the baffle on the straight ejector block presses the top pin, and the top pin applies the pressure to the sliding plate, thereby squeezing out the lubricating oil in the sponge block to lubricate between the straight ejector block and the backing plate, thus reducing the friction between the straight ejector block and the backing plate.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0018] Please refer to Figure 1-2 , a combined structure in which a straight ejector drives an inclined ejector to slide, including a moving template 2 and an ejector plate 6. A plastic part 1 is arranged inside the moving template 2. A backing plate 5 is installed on the right side of the moving template 2 through bolts. An inclined ejector block 3 is slidably connected inside the moving template 2. A straight ejector block 4 is installed inside the ejector plate 6 through bolts. The straight ejector block 4 penetrates through the backing plate 5 and the moving template 2 and is slidably connected to both the backing plate 5 and the moving template 2. The straight ejector block 4 is slidably connected to the inclined ejector block 3. A slider 41 is fixedly connected to one side of the straight ejector block 4 close to the inclined ejector block 3. A chute is opened on one side of the inclined ejector block 3 close to the straight ejector block 4, and the slider 41 is slidably connected to the inside of the chute. Through the setting of the slider 41, when the straight ejector block 4 moves, the inclined ejector block 3 can be subjected to a force in the parallel direction of the slider 41.

[0019] Please refer to Figure 1 , Figure 3 , a hollow shell 7 is fixedly connected inside the backing plate 5, and the hollow shell 7 is slidably connected to the straight ejector block 4. A slide plate 8 and a sponge block 9 are slidably connected inside the hollow shell 7, and the slide plate 8 and the sponge block 9 are in contact with each other. An oil drain hole 14 is opened on one side of the hollow shell 7 close to the straight ejector block 4. An ejector pin 11 is fixedly connected to one side of the slide plate 8 away from the sponge block 9. The ejector pin 11 penetrates through the hollow shell 7 and is slidably connected to the hollow shell 7. A baffle 13 is fixedly connected to the outside of the straight ejector block 4, and the baffle 13 abuts against the ejector pin 11. By applying the reaction force on the ejector pin 11 through the baffle 13, the sponge block 9 inside the slide plate 8 is squeezed.

[0020] Please refer to Figure 3 , a spring 12 is sleeved on the outer side of the pin body of the ejector pin 11. One end of the spring 12 is fixedly connected to the slide plate 8, and the other end of the spring 12 is fixedly connected to the inner surface of the hollow shell 7. Through the setting of the spring 12, elastic force can be applied to the slide plate 8. Two through holes 10 are opened inside the slide plate 8. Through the setting of the through holes 10, it is convenient for lubricating oil to leak out through the slide plate 8.

[0021] The specific implementation process of the present utility model is as follows: During use, after the plastic part 1 is formed on the moving template 2, the ejector plate 6 drives the straight ejector block 4 to move. While the straight ejector block 4 is moving, under the action of the slider 41, the inclined ejector block 3 moves in the parallel direction of the slider 41 and finally disengages from the plastic part 1, achieving the purpose that the straight ejector block 4 has sufficient moving space.

[0022] Moreover, when the straight ejector block 4 is reset, the baffle 13 on the straight ejector block 4 presses on the ejector pin 11, and the ejector pin 11 acts on the slide plate 8 with the pressure, thereby squeezing out the lubricating oil in the sponge block 9 to lubricate between the straight ejector block 4 and the backing plate 5, thus reducing the friction between the straight ejector block 4 and the backing plate 5.

[0023] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
