fig. 2 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
As shown in fig. 1 to 2: automatic disconnected material injection mold, which comprises a mold body, the mould body includes fly leaf 1, fixed plate 2 and shaping slider 3, shaping slider 3 activity is located on fly leaf 1, fly leaf 1 is upper and lower coincide with fixed plate 2 and is connected, be equipped with the die cavity 31 that is used for the shaping to mould in the shaping slider 3, and the material way 32 that is linked together with die cavity 31, fly leaf 1 endotheca has mold core 33, the upper end of mold core 33 inserts in die cavity 31, mold core 33 lower extreme links firmly with fixed plate 2, shaping slider 3 bottom still is equipped with the liftout hole 34 that is linked together with the material way 32, fixed plate 2 is equipped with trepanning 35, be equipped with mobilizable push rod 36 in the trepanning 35, the upper end and fly leaf 1 of push rod.
The movable plate 1 is slidably sleeved with the mold core 33.
The movable plate 1 is internally sleeved with a material pulling rod 4, the lower end of the material pulling rod 4 is fixedly connected with the fixed plate 2, and the upper end of the material pulling rod 4 is inserted into the material ejecting hole 34.
The forming slide block 3 comprises a left slide block 5 and a right slide block 6, the left slide block 5 is provided with a first forming groove 51, and the right slide block 6 is provided with a second forming groove 61.
The left slider 5 and the right slider 6 are spliced to form the forming slider 3, and the first forming groove 51 and the second forming groove 61 are combined to form the cavity 31.
The left slide block 5 and the right slide block 6 are consistent in structure.
A limiting rod 7 is arranged between the movable plate 1 and the fixed plate 2, the limiting rod 7 is sleeved with the movable plate 1 in a sliding mode, the lower end of the limiting rod 7 is fixedly connected with the fixed plate 2, and the upper end of the limiting rod 7 is connected with the movable plate 1 in a limiting mode.
And (3) demolding of the plastic part:
after the plastic part is formed in the mold body, the forming slide block 3 is separated from the plastic part through an inclined guide pillar component on the mold body, then the push rod 36 is connected with a power executing element (oil cylinder), the power executing element drives the push rod 36 to push the movable plate 1 upwards continuously, the movable plate 1 slowly and upwards translates in the vertical direction, the movable plate 1 upwards translates in the process of upwards translating, when the top surface of the movable plate 1 is abutted to the bottom surface of the plastic part, the movable plate 1 can drive the plastic part to upwards move together and separate from the mold core 33, separation of the plastic part from the mold core 33 is realized, and the movement of the power executing element is stopped until the plastic part completely leaves from the mold core 33.
The plastic part is separated from the stub bar in the demoulding process:
during the upward translation of the movable plate 1 by a distance S1 (S1 is the distance between the bottom surface of the plastic part and the top surface of the movable plate 1 in the vertical direction), the joint between the plastic part and the stub bar is broken, and the stub bar is separated from the plastic part.
The reason why the plastic part is separated from the stub bar in the demolding process is as follows:
because the material ejecting hole 34 and the cavity 31 are both communicated with the material channel 32, after the plastic part is molded, the material (hereinafter referred to as a material column) in the material ejecting hole 34 is connected with the stub bar and the plastic part, and the plastic part is connected with the mold core 33, and the material column always abuts against the top surface of the movable plate 1, when the movable plate 1 starts to translate to the process that the top surface of the movable plate just contacts with the bottom surface of the plastic part (i.e. the distance of translation S1), the stub bar continuously receives the acting force of the upward ejection of the material column, but the acting point of the acting force is on the stub bar and is not enough to drive the plastic part to separate from the mold core 33, so that the joint of the stub bar and the plastic part is broken, and the separation of the stub bar and the plastic part is realized.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
