The process does not require workers to manually apply oil, thereby effectively reducing the labor intensity of workers and facilitating use.

[0018] 2. When the push plate pushes the clamping frame to gather the oil shells on the surface of the ejector pin, the step section of the clamping frame will press against the No. 2 carrier to limit the clamping frame so that the two gathered oil shells remain stationary. At this time, the push sleeve will continue to move to drive the ejector pin to continue to move downward to slide in the sponge sleeve, so that the oil can be evenly applied to the surface of the ejector pin. During this process, the push plate will remain stationary and offset the deformation of the spring, so that the push frame can move normally and the ejector pin will not be hindered when it continues to move downward, thereby ensuring that the oil can be evenly applied to the ejector pin.

A push pin is installed on the inner bottom surface of the mold base 1. The mold base 1 plays a role in supporting the injection mold 2. A plurality of ejector pins 10 are slidably installed through the bottom of the injection mold 2. The ejector pins 10 can slide in the injection mold 2 to eject the molded plastic interior parts for demoulding. A needle seat 21 is fixedly installed at the lower end of the plurality of ejector pins 10. The needle seat 21 plays a role in supporting the injection mold 2. The ejector pin 10 is supported, the needle seat 21 is connected to the push pin part, two groups of oil shells 22 are elastically installed on the upper part of the inner part of the mold base 1, and the number of each group of oil shells 22 is two. The oil shells 22 play the role of storing oil. The ejector pin 10 passes through the two oil shells 22. The opposite surfaces of the two oil shells 22 are installed with multiple sponge sleeves 30. The sponge sleeves 30 can absorb the oil in the oil shells 22 to apply it on the ejector pin 10. The sponge sleeves 30 correspond to the ejector pin 10, and the oil shells 22 are connected to the push pin part.

[0029] An oil inlet 32 ​​is provided at the upper end of the oil shell 22, and the oil inlet 32 ​​serves to inject oil into the oil shell 22. The oil inlet 32 ​​can be sealed by screwing a cover on it. A plurality of receiving grooves 31 are provided on the opposite surfaces of the two oil shells 22.

An oil outlet 36 is provided on the inner surface of the receiving groove 31, and the oil outlet 36 serves to supply oil. A sponge column 35 extends from the outer surface of the sponge sleeve 30, and the sponge column 35 is tightly attached to the inside of the oil outlet 36. The sponge column 35 can block the oil outlet 36 to prevent a large amount of oil from flowing out. At the same time, the sponge column 35 can also absorb the oil and conduct it to the sponge sleeve 30 to be absorbed by the sponge sleeve 30, so as to facilitate subsequent extrusion to coat the ejector pin 10. The sponge sleeve 30 and the sponge column 35 are integrally formed.

[0030] A bearing plate 3 is fixedly installed on the upper part of the interior of the mold base 1, and the ejector pin 10 passes through the lower end of the bearing plate 3.

[0031] Two sets of sliding sleeves 25 are symmetrically mounted on the outer surface of the bearing column 24, and each set of sliding sleeves 25 has two sets. The bearing column 24 and the sliding sleeves 25 guide the oil shell 22. The two sliding sleeves 25 are respectively fixed to the two oil shells 22. A No. 2 return spring 26 is wound around the outer side of the bearing column 24. The two ends of the No. 2 return spring 26 are respectively fixed to the two sliding sleeves 25. The No. 2 return spring 26 separates and returns the two gathered oil shells 22. One of the sliding sleeves 25 is attached to the fixing frame 23. A T-shaped frame 27 is fixedly installed on the side of a fixed frame 23. The T-shaped frame 27 serves to carry the gear 29. Gears 29 are rotatably installed at both ends of the T-shaped frame 27. The upper and lower parts of the gear 29 are meshed with tooth plates 28. The two tooth plates 28 are respectively fixed to the two sliding sleeves 25. The gear 29 and the tooth plate 28 enable the two oil shells 22 to move synchronously towards each other. When one of the oil shells 22 is pushed, the other oil shell 22 can also move synchronously, so that the two oil shells 22 are gathered or separated.

[0032] The needle pusher includes a servo push cylinder 5 fixedly mounted on the inner bottom surface of the mold base 1, and a push sleeve 8 is fixedly mounted on the output end of the servo push cylinder 5. The servo push cylinder 5 drives the push sleeve 8 to move. A top frame 7 is rotatably mounted on the upper end of the push sleeve 8. The end of the top frame 7 is rotatably connected to the middle part of the lower end of the needle seat 21. The top frame 7 is inclined. The push sleeve 8 can drive the top frame 7 to move to drive the needle seat 21 to move up and down. Two guide rods 20 are symmetrically fixedly mounted on the lower end of the bearing plate 3. The lower end of the guide rod 20 is fixed to the inner bottom surface of the mold base 1, and the needle seat 21 is slidably mounted on the surface of the guide rod 20. The guide rod 20 plays a role in vertically guiding the needle seat 21.

[0033] A guide column 4 is fixedly installed on the inner bottom surface of the mold base 1. The guide column 4 is located on the side front of the servo push cylinder 5. The push sleeve 8 is slidably installed on the surface of the guide column 4. The guide column 4 plays a role in guiding the push sleeve 8. A push frame 6 is fixedly installed on the front end of the push sleeve 8. A push plate 14 is elastically installed on the end of the push frame 6. The push frame 6 plays a role in supporting the push plate 14. Two clamping frames 9 are symmetrically and elastically installed on the upper end of the bearing plate 3. The two clamping frames 9 are respectively located at the front and rear of the oil shell 22. The push plate 14 plays a role in pushing the concave frame 15. A gathering frame 33 is rotatably installed at one end of the clamping frame 9. The clamping frame 9 can drive the gathering frame 33 to move to push one of the oil shells 22 so that the two oil shells 22 can be gathered together. The end of the gathering frame 33 is rotatably connected to one of the oil shells 22, and the gathering frame 33 is inclined.

[0034] The outer surface of the clamping frame 9 is fitted with a No. 2 carrier 34 and a No. 1 carrier 18. The No. 1 carrier 18 is located on the side of the No. 2 carrier 34. The No. 2 carrier 34 and the No. 1 carrier 18 play a role in guiding the clamping frame 9. A guide column 16 is fixedly installed on the side of the No. 1 carrier 18. A concave frame 15 is fixedly installed between the other ends of the two clamping frames 9. The push plate 14 is fitted on one side of the concave frame 15. The concave frame 15 plays a role in connecting the two clamping frames 9 together so that they can move synchronously. The guide column 16 penetrates from one side of the concave frame 15, and the guide column 16 and the concave frame 15 are fixedly installed. The concave frame 15 is slidably matched, and the end of the guide column 16 is coaxially inlaid with a limiting cap 19. The limiting cap 19 limits the reset position of the clamping frame 9.

[0035] Two limiting columns 13 are symmetrically fixedly installed on the side of the push plate 14. The limiting columns 13 slide through the end of the push frame 6. The limiting columns 13 play a role in guiding the push plate 14. The end of the limiting column 13 is inlaid with an anti-drop cap 12. The anti-drop cap 12 fits on one side of the push frame 6. The anti-drop cap 12 plays a role in preventing the push frame 6 and the limiting column 13 from separating. A counteracting spring 11 is wrapped around the outside of the limiting column 13. When the two oil shells 22 gather together, the counteracting spring 11 can offset the thrust generated by the continued movement of the push frame 6. One end of the counteracting spring 11 is fixed to the push plate 14, and the other end of the counteracting spring 11 is fixed to the other side of the push frame 6.

[0036] A method for using an injection mold for an interior trim of a new energy vehicle is also provided, comprising the following steps:

[0037] S1: The servo push cylinder 5 drives the ejector frame 7 on the push sleeve 8 to move, so that the ejector pin 10 moves downward and is pulled out of the injection mold 2;

[0038] S2: The push frame 6 moves synchronously to drive the push plate 14 to push the clamping frame 9, thereby driving the gathering frame 33 to move and push the oil shells 22, so that the two oil shells 22 are gathered together;

[0039] S3: At this time, the gathered oil shell 22 will squeeze the sponge sleeve 30 onto the ejector pin 10 , so that the oil absorbed in the sponge sleeve 30 can be squeezed out to adhere to the surface of the ejector pin 10 moving downward, so as to complete the lubrication of the ejector pin 10 .

[0040] When in use, the raw material can be injected into the injection mold 2. After it is cooled and formed, the injection mold 2 can be opened. Then the servo push cylinder 5 works to drive the push frame 7 on the push sleeve 8 to move to push the needle seat 21. At this time, the needle seat 21 slides on the guide rod 20 to assist the movement of the needle seat 21, so that the ejector 10 on the needle seat 21 can move up to push the injection molded part formed in the injection mold 2 to eject it from the injection mold 2 to complete demoulding, thereby obtaining the interior parts of the new energy vehicle. After the demoulding is completed, the servo push cylinder 5 can drive the push sleeve 8 to move in the opposite direction to drive the ejector 10 to move down and reset. At this time, the push plate 14 on the push frame 6 just fits with the concave frame 15. If the ejector 10 is short of oil, the servo push cylinder 5 can drive the push sleeve 8 to continue to move in the opposite direction so that the ejector 10 can move down to be extracted from the lower end of the injection mold 2. In this process, the push frame 6 will move synchronously to drive the push plate 14 to push the concave frame 15. The oil shells 22 are pushed together by the push plate 14, and the push plate 14 is pressed against ...
