[0020] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0021] Please refer to Figure 2 The embodiment of the utility model provides an automatic ejector device, including a lifting drive device 1, a lifting seat 2, a lifting mounting plate 3 and a plurality of groups of ejector devices 4. The various components of this embodiment are described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 2 As shown, the lifting drive device 1 is transmission-connected with the lifting seat 2 and can drive it to move up and down. In this embodiment, the lifting drive device 1 can be preferably configured as a linear drive module driven by a motor. Of course, other lifting devices can also be used according to actual needs.

[0023] The lifting installation plate 3 is installed on the lifting seat 2, and the material stripping and ejecting devices 4 are evenly installed on the surface of the lifting installation plate 3. The material stripping and ejecting devices 4 can preferably be provided with four groups.

[0024] like Figure 3 and Figure 4 As shown, each group of ejection devices 4 can include an ejection mounting plate 41, a sprue ejector pin 42 and a product ejector block 43. The sprue ejector pin 42 and the product ejector block 43 are both transversely mounted on the ejection mounting plate 41 and protrude from the surface of the ejection mounting plate 41. The sprue ejector pin 42 is located above the corresponding product ejector block 43.

[0025] Specifically, the ejector mounting plate 41 may include a bottom plate 411 , an intermediate plate 412 and a panel 413 connected in sequence from the inside to the outside, the tail end of the sprue ejector pin 42 is installed on the intermediate plate 412 , and the head end of the sprue ejector pin 42 passes through the outside of the panel 413 .

[0026] like Figure 4 As shown, the product stripping top block 43 can be installed in the mounting hole opened on the surface of the panel 413, and the product stripping top block 43 is fixedly connected to the screws 44 installed on the middle plate 412.

[0027] As a further improvement of this embodiment, a V-shaped groove 431 may be provided at the head end of the product stripping top block 43, so that the upper and lower ends of the head end of the product stripping top block 43 both protrude from the middle part. When the product stripping top block 43 pushes the product, the upper and lower ends of the head end of the product stripping top block 43 first contact the product. At this time, the middle part of the product is bent inwardly (V-shaped bend) toward the inside of the V-shaped groove, which is more conducive to product ejection and can avoid the product being turned outward and damaged, affecting the product quality.

[0028] Preferably, each ejector mounting plate 41 may be provided with four sprue ejector pins 42 and four product ejector ejector blocks 43. Of course, the number of sprue ejector pins 42 and product ejector ejector blocks 43 may be increased or decreased arbitrarily according to actual needs, and is not limited to this embodiment.

[0029] like Figure 2 As shown, preferably, the lifting seat 2 can also be provided with a shield 5 located outside the lifting mounting plate 3 and the stripping and ejecting device 4. The shield 5 can play a material blocking role to prevent the product being fixed from falling to a non-specified position.

[0030] The automatic ejector device of this embodiment can be used in conjunction with an injection mold of an injection molding machine, wherein Figure 5 and Figure 6 As shown, the injection mold may include a front mold 11, a middle mold 12 and a rear mold 10, and the middle mold 12 is provided with a plurality of molding positions 121 and a glue feeding position 122 for product injection molding. After the injection mold has injection-molded the product, the mold will be opened, and the front mold 11, the middle mold 12 and the rear mold 10 will be separated from each other. The lifting drive device can drive the sprue ejector pin 42 and the product ejector block 43 on the lifting mounting plate 3 to move downward to one side of the middle mold, and then the middle mold driving cylinder 111 drives the middle mold 12 to move horizontally, so that the middle mold 12 moves toward the sprue ejector pin 42 and the product ejector block 43. At this time, the sprue ejector pin 42 can eject the sprue at the glue feeding position 122 of the middle mold 12, and the product ejector block can eject the product at the molding position 121 of the middle mold 12.

[0031] In summary, the utility model has reasonable structural design, high working efficiency, low noise and good demoulding effect.

[0032] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
