A track protection device for injection molding machines specially used for pipe fittings

Abstract

The present invention discloses a track protection device for a special injection molding machine for pipe fittings, including a bearing member and a lifting mechanism, a discharging assembly is arranged above one end of the bearing member, and a bolt-assembled clamping structure is arranged above the inner side of the bearing member. The device of the invention mainly utilizes the output power of the second cylinder to drive the lifting rod and the square table to cooperate with the spherical top rod to separate the mold base from the clamping slot seat, so that the pipe fitting mold base and the pipe fitting mold shell are separated from the track for injection molding. When the injection molding is completed, the lifting rod and the square table are driven by the output power of the second cylinder to cooperate with the spherical top rod to reset the mold base to the clamping slot seat. Since there is a shock absorber between the bolt base and the support plate, and the sleeve shell is arranged on the outer side of the inner slider, the electric screw protected by the telescopic canvas cover can be better protected under the effect of shock absorption. Therefore, during the injection molding process, the damage to the track caused by inertia is significantly reduced, thereby increasing the service life of the track.

Description

Technical Field

[0001] The invention relates to the technical field of injection molding machine tracks, in particular to a special injection molding machine track protection device for pipe fittings. Background Art

[0002] Plastic pipes mainly include UPVC drainage pipes, UPVC water pipes, aluminum-plastic composite pipes, polyethylene (PE) water pipes, and polypropylene PPR hot water pipes. Injection molding machines, also known as injection molding machines or injection machines, are the main molding equipment for making plastic products of various shapes from thermoplastics or thermosetting plastics using plastic molding molds. With the improvement of social productivity and demand, large-scale plastic production requires the use of rails to transport raw materials and products. Therefore, the protection of rails is a necessary means to ensure production efficiency.

[0003] When the existing injection molding machine track protection equipment is in use, it is usually carried by a power device such as a screw rod or a mechanical arm to carry the mold or the injection molding machine, so that the raw materials can be accurately injected to achieve the effect of forming the product. For example, application number CN201520951398.7 discloses a movable template sliding track of an injection molding machine, which discloses: "A pulling device 3 is provided between the other end and the frame 1, and the pulling device 3 includes a stretching member 31 and a power member 32. The stretching member 31 is an "L"-shaped metal plate, which includes a first bending plate 311 and a second bending plate 312, wherein the first bending plate 311 and the steel belt 2 are provided with a through strip hole 6"; However, in the above technology, although there is a certain degree of protection for the track, there is still a certain degree of damage. During the injection molding process, the track will be severely worn due to the effect of inertia.
