DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Apparently, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the utility model.

[0023] Embodiment 1: please refer to Figures 1-5 A kind of injection molding machine for processing luggage pull rod, including base 1, base 1 is installed with support 2, electric telescopic rod one 8 is installed on support 2, the inner side both ends of support 2 are fixedly installed with sliding rod 21, heat dissipation assembly 7 is arranged on sliding rod 21, heat dissipation assembly 7 includes heat dissipation frame 71, heat dissipation frame 71 is slidably installed on sliding rod 21, heat dissipation frame 71 is connected with the output end of electric telescopic rod one 8, heat dissipation frame 71 is connected with mould 6 by connecting bolt, installation groove 73 is set up on the side of heat dissipation frame 71 close to mould 6, heat conduction plate 74 is installed in installation groove 73, heat conduction plate 74 is attached to mould 6, heat conduction plate 74 is arrayed with cooling fin 75, heat dissipation fan 72 is installed on heat dissipation frame 71.

[0024] Specifically, heat is generated in the mold 6 during the injection molding process. Since the heat-conducting plate 74 is closely attached to the mold 6 and is made of a material with good heat conduction performance, the heat of the mold 6 is efficiently conducted to the heat-conducting plate 74, and the heat dissipation fins 75 arranged on the heat-conducting plate 74 further increase the heat dissipation area. The heat is dispersed from the heat-conducting plate 74 to each heat dissipation fin 75, so that the heat can be more easily dissipated into the surrounding air. At the same time, when the heat dissipation fan 72 installed on the heat dissipation rack 71 is working, it can accelerate the flow of the surrounding air. The flowing air constantly sweeps over the heat dissipation fins 75, taking away the heat on the heat dissipation fins 75. Through the way of air convection, the heat is finally dissipated to the surrounding environment from the mold 6, through the heat-conducting plate 74 and the heat dissipation fins 75, realizing the cooling and heat dissipation of the mold 6. After cooling is completed, the cooling assembly 7 driven by the electric telescopic rod 1 is used to control the mold 6 to move along the slide rod 21, so as to separate the two molds 6, and then facilitate the finished product to fall on the base 1, which is helpful for the operator to collect and process.

[0025] Through the synergistic effect of the heat-conducting plate 74, the heat dissipation fins 75 and the heat dissipation fan 72, efficient heat dissipation can be achieved. Compared with some traditional natural cooling methods, the forced convection effect of the heat dissipation fan 72 greatly accelerates the speed of heat dissipation, so that the mold 6 can be cooled to a suitable temperature in a shorter time, thereby improving the efficiency of injection molding production and shortening the production cycle. At the same time, this dry heat dissipation method does not need to use cooling water, so it can avoid a series of problems caused by the attachment of cooling water on the product, reduce the degree of complexity of subsequent work, avoid the corrosion and oxidation of the surface of the finished product caused by water stains, or the appearance affected by water stains, and effectively improve the surface quality of the luggage pull rod.

[0026] In order to realize stable feeding, please refer to Figures 1-5 On the basis of embodiment 1, the support frame 5 is fixedly installed on the support 2, and the storage box 4 is installed on the support frame 5.

[0027] The feeding assembly 3 is installed on the support 2, and the feeding assembly 3 comprises a feeding pipe 35 and a discharging pipe 36. One end of the feeding pipe 35 is connected with the storage box 4, one end of the discharging pipe 36 is connected with the mold 6, and the other end of the feeding pipe 35 and the discharging pipe 36 is connected with the feeding groove 31.

[0028] The piston plate 341 is slidably installed in the feeding groove 31, the piston plate 341 is fixedly connected with the push rod 34, and the push rod 34 penetrates through the feeding groove 31 and is connected with the connecting plate 33.

[0029] The second electric telescopic rod 32 is fixedly installed on one side of the feeding groove 31, and the output end of the second electric telescopic rod 32 is connected with the connecting plate 33.

[0030] The feeding pipe 35 and the discharging pipe 36 are fixedly provided with a ring 37, one side of the ring 37 is provided with a blocking block 38, the blocking block 38 is fixedly connected with a guide rod 381, the guide rod 381 is slidably penetrated through the middle of a fixed frame 39, the blocking block 38 is connected with the fixed frame 39 through a spring 382, the blocking block 38 in the feeding pipe 35 is arranged at the inner side of the inner ring 37, and the blocking block 38 in the discharging pipe 36 is arranged at the outer side of the inner ring 37.

[0031] Specifically, when the electric telescopic rod two 32 is telescoped, the connecting plate 33 is moved, and then the push rod 34 is pushed to make the piston plate 341 slide in the feeding groove 31. When the piston plate 341 slides forward, the material in the feeding groove 31 is extruded, so that the material is stably supplied into the mold 6 through the discharging pipe 36; when the piston plate 341 slides backward, the material in the feeding pipe 35 is sucked into the feeding groove 31, so as to prepare for the next feeding;

[0032] The feeding pipe 35 and the discharging pipe 36 are provided with a valve structure composed of the ring 37 and the blocking block 38. In the feeding pipe 35, the blocking block 38 is located at the inner side of the ring 37, when the piston plate 341 moves backward to generate suction, the pressure of the material can overcome the elastic force of the spring 382, so that the blocking block 38 is opened, and the material smoothly enters the feeding groove 31; when the piston plate 341 moves forward to feed, the pressure of the material makes the blocking block 38 closed, so as to prevent the material from flowing back. In the discharging pipe 36, the blocking block 38 is located at the outer side of the ring 37, when the piston plate 341 moves forward to feed, the material pushes the blocking block 38 to open, and the material flows to the mold 6; after the feeding is completed, the elastic force of the spring 382 makes the blocking block 38 closed, so as to avoid the material in the mold 6 from flowing back to the feeding groove 31, thereby ensuring the unidirectionality and stability of the material supply;

[0033] Through the accurate control of the displacement of the piston plate 341 by the electric telescopic rod two 32, the amount of each feeding can be accurately controlled, and the valve structure in the feeding pipe 35 and the discharging pipe 36 effectively prevents the backflow of the material, guarantees the efficiency of the feeding, and avoids repeated feeding.

[0034] Working principle: when the equipment is used, the electric telescopic rod one 8 controls the two molds 6 to move along the slide rod 21, and makes the two molds 6 abut to form a complete injection cavity, the electric telescopic rod two 32 is telescoped, the connecting plate 33 is moved, and then the push rod 34 pushes the piston plate 341 in the feeding groove 31, when the piston plate 341 slides backward, suction is generated, the material overcomes the elastic force of the spring 382 in the feeding pipe 35 to make the blocking block 38 open, so as to facilitate the material in the storage box 4 to enter the feeding groove 31, when the piston plate 341 slides forward, the material pushes the blocking block 38 in the discharging pipe 36 to open the discharging, and supplies the material to the injection cavity, after the feeding is completed, the spring 382 makes the blocking block 38 closed;

[0035] After the finished product is completed, the heat of the finished product is transferred to the heat-conducting plate 74 through the mold 6, and then is dispersed to the radiating fins 75. The radiating fan 72 works to accelerate the air flow, so that the air flows over the radiating fins 75 to take away the heat, and the mold 6 is cooled and radiated through air convection. After the cooling is completed, the electric telescopic rod 8 drives the radiating assembly 7 to move reversely along the slide rod 21, drives the mold 6 to separate, so that the finished product falls to the base 1, and the operator is convenient to collect and process.
