[0002] Injection molding machine includes fuselage 1 and the machine body erected on fuselage 1, and the machine body includes mold clamping mechanism and injection mechanism, and fuselage 1 includes mold clamping frame 101 for supporting mold clamping mechanism and injection frame 102 for supporting injection mechanism.

[0003] The Chinese patent with application No.201420679952.6 discloses a three-plate type injection molding machine front mold plate pressurization leak-proof device, which comprises an injection molding machine rack base (fuselage), a mold clamping mechanism and an injection mechanism are arranged on the injection molding machine rack base, the mold clamping mechanism comprises a front mold plate (head plate) close to the injection mechanism, a rear mold plate (tail plate) away from the injection mechanism, and a movable mold plate (second plate) reciprocally moving between the front mold plate and the rear mold plate to open and close the mold, an open-close mold oil cylinder is installed on the rear mold plate, and the open-close mold oil cylinder drives the movable mold plate to open and close the mold through a mold clamping transmission mechanism (open-close mold joint).

[0004] The mold clamping frame 101 comprises a mold clamping support 101a and a top plate 101b fixed to the upper end face of the mold clamping support 101a, and the mold clamping mechanism is installed on the top plate 101b. A blanking port 2 is arranged on the top plate 101b, and when the second plate moves away from the head plate to open the mold, the product falls through the blanking port 2 to the lower side of the top plate 101b for collection.

[0005] The existing mold clamping mechanism further comprises a pull rod arranged between the tail plate and the head plate along the moving direction of the second plate, the pull rod is provided with four pull rods respectively located at four end points of the head plate, and the second plate is slidably connected with the pull rod. The second plate sliding feet are arranged on both sides of the blanking port 2 at the bottom of the second plate, and a steel belt 13 is arranged on the top plate 101b along the moving direction of the second plate for sliding of the second plate sliding feet. That is, the pull rod and the steel belt 13 are both located on both sides of the blanking port 2.

[0006] In order to reduce the jamming, lubricating oil is added between the open-close mold joint, the second plate and the pull rod, and between the steel belt 13 and the second plate sliding feet. The side of the head plate close to the tail plate also has residual lubricating oil when the mold is installed. The above-mentioned lubricating oil will drip and form waste oil during the use of the injection molding machine.

[0007] Therefore, in the prior art, referring to Figure 1 , an oil falling port 3 is arranged below the open-close mold joint on the top plate 101b, and an oil receiving disc 4 is arranged below the oil falling port 3. The oil receiving disc 4 is used to receive the waste oil dripping from the open-close mold joint, and the waste oil dripping on the top plate 101b can also flow into the oil receiving disc 4 for collection. The blanking port 2 is circumferentially provided with an oil baffle 5 to prevent the waste oil from flowing into the blanking port 2.

[0008] However, in order to ensure the precision of the mold closing mechanism installed on the top plate 101b, the upper end surface of the top plate 101b is a horizontal surface, and since the flowability of the waste oil is poor, the waste oil is prone to accumulate near the material falling port 2; and the height of the oil baffle 5 around the material falling port 2 is limited, which will cause the accumulated waste oil to overflow the oil baffle 5 and enter the material falling port 2 to contaminate the product. Content of the utility model

[0009] The utility model provides a injection molding machine body with waste oil collecting function, which solves the problem of waste oil accumulation on the top plate and the problem of waste oil overflowing the oil baffle and entering the material falling port to contaminate the product in the prior art.

[0010] In order to solve the above technical problems, the utility model solves the problems through the following technical schemes:

[0011] A injection molding machine body with waste oil collecting function, comprising a mold closing frame and an injection frame connected in head and tail, the mold closing frame comprising a mold closing support and a top plate fixed to the mold closing support and cooperating with the mold closing support to form a material falling port and an oil falling port, an oil receiving tray is arranged below the oil falling port, a first oil guide groove is arranged below the top plate on both sides of the material falling port to receive the waste oil flowing down on the top plate on both sides of the material falling port and guide the waste oil into the oil receiving tray, and a second oil guide groove is arranged at one end of the material falling port close to the injection frame to receive the waste oil dripping on the head plate and guide the waste oil into the first oil guide groove.

[0012] According to the above scheme, the waste oil on the mold opening and closing joint falls into the oil receiving tray. The waste oil on the pull rod, the two-plate sliding foot and the steel belt falls on the part of the top plate located on both sides of the material falling port, that is, falls on the top plate on both sides of the material falling port. The waste oil on the head plate falls into the second oil guide groove. The waste oil received by the top plate on both sides of the material falling port and the second oil guide groove flows into the first oil guide groove, and then finally flows into the oil receiving tray through the first oil guide groove. The waste oil near the material falling port is quickly discharged, preventing the waste oil from accumulating near the material falling port.

[0013] As a preferred, the side of the top plate close to the oil receiving tray and the first oil guide groove is downwardly bent to form an oil guide bent edge for guiding the waste oil on the top plate into the oil receiving tray and the first oil guide groove.

[0014] According to the above scheme, after the waste oil falls on the top plate on both sides of the material falling port, the waste oil flows on the entire top plate when there is a large amount of waste oil due to the flowability of the waste oil. Secondly, the two-plate and the mold opening and closing joint are in a moving state when the mold closing mechanism is working, rather than completely stationary, so the lubricating oil does not completely vertically fall, and there is a risk of being thrown to the entire upper end surface of the top plate. Therefore, the side wall of the top plate close to the oil receiving tray and the first oil guide groove is downwardly bent to form an oil guide bent edge, which guides the waste oil on the top plate around the oil receiving tray into the oil receiving tray and guides the waste oil on the top plate on both sides of the material falling port into the first oil guide groove.

[0015] Preferably, the first oil guide groove is downwardly inclined towards the oil receiving tray.

[0016] With the above scheme, the lubricating oil flows into the oil receiving tray quickly under the action of its own gravity.

[0017] Preferably, the first oil guide groove is downwardly inclined towards the oil receiving tray.

[0018] With the above scheme, the lubricating oil flows into the oil receiving tray quickly under the action of its own gravity.

[0019] Preferably, the second oil guide groove is downwardly inclined towards the oil receiving tray.

[0020] With the above scheme, the lubricating oil flows into the oil receiving tray quickly under the action of its own gravity.

[0021] Preferably, the second oil guide groove is downwardly inclined towards the oil receiving tray.

[0022] With the above scheme, the lubricating oil flows into the oil receiving tray quickly under the action of its own gravity.

[0023] Preferably, the second oil guide groove is downwardly inclined towards the oil receiving tray.

[0024] With the above scheme, the lubricating oil flows into the oil receiving tray quickly under the action of its own gravity.

[0025] Preferably, the second oil guide groove is downwardly inclined towards the oil receiving tray.

[0026] With the above scheme, the lubricating oil flows into the oil receiving tray quickly under the action of its own gravity.

[0027] This utility model, by adopting the above technical solution, has significant technical effects: the oil receiving tray, top plate, and second oil guide groove receive dripping waste oil. Waste oil on the top plate around the oil receiving tray is guided into the oil receiving tray through the oil guide folding edge. Waste oil on the top plates on both sides of the discharge port is guided into the first oil guide groove through the oil guide folding edge. Waste oil in the second oil guide groove flows into the first oil guide groove through the notch and oil guide folding edge, and then flows into the oil receiving tray together with the waste oil flowing into the first oil guide groove from the top plate. Finally, the waste oil on the machine body collects in the oil receiving tray, allowing the waste oil near the discharge port to be quickly discharged and preventing waste oil from accumulating near the discharge port.
