Compared with the prior art, the beneficial effects of the utility model are that: this injection mold with structure of loosing core simple structure, reasonable in design can play certain cushioning effect at the in-process of loosing core through buffer structure, and the effectual solution is when the contact site area of core and product is big, perhaps contacts between the two too closely, if adopt once to force to loose core and can produce the flower on the product, even breaks through for product quality is impaired, the problem that the rejection rate increases.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
The injection molding device comprises a mounting frame, a hydraulic cylinder, a mounting plate, a core body, an injection mold body, a buffer structure, a sleeve, a sliding chute, a buffer spring, a connecting rod, a sliding block, a damping spring, a sponge cushion, a telescopic rod and a protection cushion, wherein the mounting frame is 1-mounting frame, the hydraulic cylinder is 2-mounting plate, the mounting plate is 3-mounting plate, the core body is 4-core body, the injection mold body is 5-injection mold body, the buffer structure is 6.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: an injection mold with a core-pulling structure comprises a mounting frame 1, wherein a hydraulic cylinder 2 is assembled on the lower wall surface of the mounting frame 1, the piston end of the hydraulic cylinder 2 is vertically downward, a mounting plate 3 is welded at the piston end of the hydraulic cylinder 2, a core body 4 is arranged at the lower end of the mounting plate 3, an injection mold main body 5 matched with the core body 4 is arranged at the lower end of the core body 4, the injection mold main body 5 is installed on a workbench, and a buffer structure 6 is assembled between the core body 4 and the mounting plate 3;
Preferably, the damping springs 7 are mounted on the left and right sides of the lower wall surface of the sleeve 61, and the sponge pad 8 is mounted on the ends of the damping springs 7 far away from the sleeve 61.
Preferably, a pair of telescopic rods 9 is assembled between the mounting frame 1 and the mounting plate 3, the upper end of each telescopic rod 9 is mounted on the lower surface of the mounting frame 1, the lower end of each telescopic rod 9 is mounted on the upper surface of the mounting plate 3, and the pair of telescopic rods 9 are respectively positioned on the left side and the right side of the hydraulic cylinder 2.
Preferably, the pair of sliders 65 is provided with a protection pad 10 on an upper wall surface thereof.
When the injection mold is used, core pulling needs to be carried out on a finished product after molding is finished, the hydraulic cylinder 2 is started, the hydraulic cylinder 2 works to drive the mounting plate 3 to move upwards, the buffer structure 6 is pulled to move upwards, so that the core body 4 is pulled to move upwards until the core body 4 is moved out of the injection mold main body 5, in the process of pulling the core body 4, the buffer structure 6 can play a role in buffering the pulling process, the phenomenon that when the area of a contact part between the core body 4 and a product is large or the contact between the core body and the product is too tight is avoided, if one-time forced core pulling is adopted, a pull pattern is generated on the product, even the product is broken, so that the quality of the product is damaged is avoided, when the buffer structure 6 is used for buffering in the pulling process, when the mounting plate 3 moves upwards, the sleeve 61 is pulled to move upwards, at the moment, the core body 4 is in close contact with the finished, play the buffering to the pulling process, avoid forcing to loose core and cause the damage to the product, damping spring 7 and foam-rubber cushion 8 through setting up, can avoid when core 4 takes out from injection mold main part 5, core 4 upwards strikes to sleeve pipe 61 under buffer spring 63's effect, cause core 4 to damage, can strengthen the connection between pneumatic cylinder 2 and the mounting panel 3 through telescopic link 9, can protect slider 65 through protection pad 10, when core 4 is taken out, because buffer spring 63's effect makes slider 65 upwards bounce, can protect slider 65 through protection pad 10, avoid slider 65 upwards striking spout 62 upper wall and damage.
