Description

Technical Field

[0001] The utility model relates to the field of injection molding machines, in particular to a protection device for a mold station mold shifting mechanism and an injection molding machine. Background Art

[0002] At present, the sliding mechanism of the injection molding machine mostly adopts the sliding friction mode of direct contact between plates. Its working state is to slide the mold in and out under high temperature conditions. Although high-temperature lubricating oil is used for lubrication, the lubrication effect is not very ideal, and it is also easy to cause poor heating effect. During use, scratches often appear between the sliding contact surfaces, which reduces the damage of the sliding mechanism to a certain extent, thereby shortening the service life.

[0003] In order to change this situation, a mold shifting mechanism is added between the plates to replace the direct contact sliding method between the plates. Although the mold shifting mechanism can greatly facilitate the sliding in and out of the mold, the mold shifting mechanism cannot withstand the pressure of the booster cylinder and is easily damaged.

[0007] Furthermore, the avoidance hole is a rectangular long hole, and a plurality of the avoidance holes are arranged in parallel and at intervals. The pressure protrusion is a block structure with a rectangular cross-section, and a plurality of the pressure protrusions are arranged in parallel and at intervals.

[0014] Furthermore, the booster cylinder is an oil cylinder.

[0015] From the above description of the utility model, it can be seen that compared with the prior art, the beneficial effects of the utility model are:

[0016] First, the mold transfer mechanism is used to replace the sliding method of direct connection between plates, which greatly improves the efficiency of sliding in and out of the mold and prevents scratches between plates.

[0025] The protection device 11 includes a middle plate 110 and a pressure plate 111. The middle plate 110 is arranged on the frame 10, and the middle plate 110 is arranged below the sliding plate 13. The mold shifting mechanism 14 is arranged on the middle plate 110 and the mold shifting mechanism 14 is connected to and drives the sliding plate 13 to slide. The pressure plate 111 can be raised and lowered below the sliding plate 13. The booster cylinder 15 is connected to and drives the pressure plate 111. A plurality of avoidance holes 1100 are opened on the middle plate 110, and the avoidance holes 1100 pass through the middle plate 110 up and down. A plurality of pressure bumps 1110 are correspondingly arranged on the pressure plate 111. The thickness of the pressure bumps 1110 is greater than the total thickness of the mold shifting mechanism 14 and the middle plate 110, so that the pressure bumps 1110 can pass through the avoidance holes 1100 to press against and press the sliding plate 13.

[0026] The sliding plate 13 can be slidably arranged on the frame 10 at the mold opening position and the mold closing position, and the sliding plate 13 is located above the middle plate 110, the mold 12 is arranged on the sliding plate 13, the linear guide rail 15 is arranged between the middle plate 110 and the sliding plate 13, the sliding plate mechanism 14 is driven to connect and drive the sliding plate 13 to slide, the pressure plate 111 can be raised and lowered below the sliding plate 13, the booster cylinder 15 is connected to and drives the pressure plate 111, and the booster cylinder 15 is an oil cylinder.

[0027] The upper plate 17 is disposed on the frame 10 and is located above the mold 12. The injection device 16 is disposed on the upper plate 17 and is connected to the mold 12 through the upper plate 17. The upper plate 17 includes a front upper plate 170 and a rear upper plate 171. The front upper plate 170 and the rear upper plate 171 are arranged in parallel and spaced apart so that a gun space 172 is formed between the front upper plate 170 and the rear upper plate 171. The injection device 16 has a gun 160. The injection device 16 is disposed above the upper plate 17 so that the gun 160 is connected to the mold 12 through the gun space 172.

[0028] The pad 19 is arranged on the sliding plate 13, the lower die mounting plate 18 is arranged on the pad 19, the mold 12 includes an upper die 120 and a lower die 121, the upper die 120 is arranged below the upper plate 17, the shooting gun 160 passes through the shooting gun space 172 to connect the upper die 120, and the lower die 121 is arranged on the lower die mounting plate 18.

Since the thickness of the pressure protrusion 1110 is greater than the total thickness of the middle plate 110 and the mold shifting mechanism 14, when the pressure protrusion 1110 presses against the sliding plate 13, the pressure plate 111 does not apply pressure to the mold shifting mechanism 14, thereby protecting the mold shifting mechanism 14 from being crushed by the booster cylinder 15.

[0030] The shooting gun 160 on the injection device 16 is connected to the shooting port on the upper mold 120 through the shooting gun space 172. Compared with the traditional method of opening a through hole on the upper plate 17 for connection, the area in the middle of the entire upper plate 17 is divided into the shooting gun space 172, which is convenient for the user to align the shooting gun 160 with the shooting port, and it is also convenient to clean the residual material at the gun head of the shooting gun 160 after the shooting is completed.
