Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1 to 7, the fully automatic injection mold for plastic products for automobiles, which is convenient to use, of the present invention includes a panel 1, an upper mold plate 2, a lower mold plate 3, square iron 4, an upper ejector plate 5, a lower ejector plate 6, and a base 7, and other structures are conventional and will not be described in detail herein. And a mold locking structure 8 is arranged between the upper template 2 and the lower template 3, and the mold locking structure 8 is arranged at four sides of the mold. This mode locking structure 8 is fixed with cope match-plate pattern 2 and lower bolster 3, need not dismantle with the help of external instrument when fixed, alright in order to take it down, also need not be with the help of external instrument during the installation simultaneously, can reach the purpose of quick installation and dismantlement.
Meanwhile, the mold locking structure 8 comprises a mold locking module 9 and a mold locking assembly 10, the mold locking module 9 is in a shape of a reverse box C, the mold locking module 9 is provided with extending parts 11 which are symmetrical up and down, and a mounting hole 18 for placing the mold locking assembly 10 is arranged in the middle of the extending parts 11. The upper and lower templates 2 and 3 have fixing holes (not shown) in which the extensions 11 are placed. And there is a space 13 between the two extensions 11, the space 13 is a travel area left for pushing the locking module 9, and after the extensions 11 of the locking module 9 are placed in the fixing holes, the wall of the space 13 is not in contact with the upper and lower templates 2 and 3, but has a distance therebetween, so that the pushing of the locking module 9 in the direction of the upper and lower templates 2 and 3 is facilitated.
The extension part 11 is sleeved with a rubber sleeve 14, the inner wall of the rubber sleeve 14 is provided with a convex part 15, the extension part 11 is provided with a matched concave part 16, and the convex part 15 is arranged in the concave part 16. The upper and lower surfaces of the rubber sleeve 14 have first serrations 17, and the fixing hole has second serrations (not shown) therein which are engaged with the first serrations 17. When the rubber sleeve 14 is heated by the molten plastic particles injected into the mold, the rubber sleeve 14 is expanded but not melted, so that the first sawtooth part 17 and the second sawtooth part are engaged, and the upper mold plate 2 and the lower mold plate 3 are fixed by the mold locking structure 8. But will not interfere with removal of the clamping structure 8.
Wherein the clamping module 10 comprises a first housing 19 and a second housing 20.
The first housing 19 has therein a first spring 22, a retainer plate 23, and an annular ring 24. The first spring 22 is located at the upper end of the retainer plate 23, and the annular ring 24 is located at the lower end of the retainer plate 23. The inner wall of the first housing has a step 25 thereon and an annular ring 24 is located at the lower end of the step 25. And the step 25 is for blocking the annular ring 24, while the limit plate 23 can be placed in the first housing 19, the limit plate 23 cooperating with the diameter of its step 25, so that the limit plate 23 can move inside the first housing 19.
The annular ring 24 has a through hole 26 in the middle, and there are four through grooves 27 on the inner wall of the through hole 26, and the inside of the through groove 27 has a limit slider 28. The limiting slide block 28 is internally provided with a limiting hole 29, the limiting slide block 28 is internally provided with a second spring 30, one end of the second spring 30 is arranged in the limiting hole 29, and the other end of the second spring is contacted with the inner wall of the through groove 27. And the annular ring 24 can be glued therein or can be mounted internally in a threaded manner.
The two side walls of the limiting slide block 28 are provided with limiting parts 31, the limiting parts 31 are provided with limiting parts 32, the annular ring 24 is provided with annular grooves 33, the limiting parts 32 penetrate through the annular grooves 33 and are arranged in the limiting parts 31, and the annular grooves 33 are arranged on the lower end face of the annular ring 24. The stopper slider 28 has an inclined surface 34, and the inclined surface 34 is inclined from the upper end surface of the stopper slider 28 toward the stopper 32. When the inclined surface 34 receives an external force, the limit slider 28 can be pushed, so that the second spring 30 is forced to contract, and the limiting member 32 moves in the annular groove 33.
Inside second housing 20 has locking member 35 and deblocking part 36, locking member 35 comprises cylinder 37 and guiding ramp 38, deblocking part 36 comprises unblocking ramp 39 and supporter 40, deblocking part 36 overlaps on cylinder 37 and is in the lower extreme of guiding ramp 38. The guiding ramp body 38 is inclined in the same direction as the inclined surface 34. The guiding ramp 38 is opposite to the direction of the ramp of the unlocking ramp 39. The support 40 is used to raise the unlocking ramp 39 so that the first housing 19 is prevented from contacting the bottom of the second housing 20 when the first housing 19 is lowered, and the unlocking member 36 cannot push the position-limiting slider 28.
The first cover 19 is fixed in the mounting hole 18 by a first bolt 41, and the second cover 20 is mounted in the fixing hole by a second bolt 42. The unlocking member 36 is fixed to the second housing 20 by a second bolt 42, so that it can be connected to the mold body.
A rotary member 21 is further provided on the lock module 9, and the rotary member 21 is hinged to the lock module 9 through a rotary shaft 12.
When the spring is installed, the rotating member 21 is held to align the extending part 11 with the fixing hole, and the first housing 19 is inserted into the second housing 20, so that the guiding inclined body 38 of the locking member 35 forces the inclined surface 34, and the limiting slider 28 forces the second spring 30 to compress. Then the upper end of locking piece 35 contacts with limiting plate 23, promotes first spring 22 to compress, then the up end of spacing slider 28 contacts with the lower terminal surface of direction clinohedral 38, blocks cylinder 37 through spacing slider 28, and first spring 22 is owing to be in compression state, can be to limiting plate 23 atress for limiting plate 23 supports locking piece 35.
When the mold locking structure 8 needs to be removed from the mold, the mold locking structure 8 is pushed toward the mold, so that the limiting slide 28 originally located between the guiding inclined plane 38 and the unlocking piece 36 is pushed by the upper end edge of the unlocking inclined plane 39 to push the inclined plane 34 and push the limiting slide 28 backward, so that the second spring 30 is compressed, then the limiting slide 28 reaches the supporting body 40 and the unlocking inclined plane 39 while the rotating piece 21 is pushed continuously, then the rotating piece 21 is pulled, so that the limiting slide 28 drives the unlocking piece 36 to move upward, after the unlocking inclined plane 39 contacts the lower end of the guiding inclined plane 38, the edge of the inclined plane 34 is guided by the unlocking inclined plane 39 to move upward obliquely, the limiting slide 28 is pushed backward while moving, so that the second spring 30 is compressed, and then the limiting slide 28 reaches the guiding inclined plane 38 from the unlocking inclined plane 39, the clamping structure 8 can be removed from the upper and lower templates 2, 3. The complicated steps of mounting and dismounting the screw are reduced, the mounting and dismounting time of the die is shortened, the time is saved, and the working efficiency is improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
