Description
Technical Field
The utility model relates to the technical field of mold processing, in particular to a mold side core-pulling positioning structure.
Background
The side core-pulling mold is widely applied to injection molding of products. When injection molding of plastic parts with holes, recesses, projections, etc. in the side walls, the parts of the mold where they are molded must be made laterally movable parts, called moving cores. Before the plastic part is demoulded, the movable core must be drawn out, otherwise the demoulding can not be carried out. The whole mechanism for driving the movable core to move laterally is called a lateral parting and core-pulling mechanism, and is called a lateral core-pulling mechanism for short. Generally, the slide block of the side core-pulling mechanism needs to be positioned by a ball-jacking screw. The outer side of the ball jacking screw is provided with a thread structure, the spring is arranged in the ball jacking screw, and the upper end of the spring is provided with a ball jacking and is limited in the ball jacking screw shell. When the die is processed, a threaded hole matched with a ball jacking screw needs to be formed in the lower die base so as to facilitate fixation. But the manual tapping hole location position machining error is big to traditional knob screw structure receives the space influence, and the spring compression ratio is big, and life is lower. Therefore, the mold side core-pulling positioning structure with accurate positioning and long service life needs to be invented.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a die side core-pulling positioning structure, which solves the problems that the service life of the traditional ball-pushing screw positioning structure is short, and the position of a threaded hole formed in a lower die holder is difficult to control, so that the positioning error is large.
The technical scheme adopted by the utility model for solving the technical problems is as follows:
the utility model provides a mould side location structure of loosing core, is provided with the slider backing plate in the die holder, the slider setting in slider backing plate top, be provided with a plurality of ball socket grooves at the lower terminal surface of slider, the die holder correspond the position of ball socket groove and seted up first locating hole, the locating hole in be provided with spring and setting element, the slider backing plate on correspond the position of first locating hole and be provided with the second locating hole, the upper end of setting element pass the second locating hole and with ball socket groove cooperation location.
Furthermore, the positioning part comprises a positioning column, a limiting block and a spring positioning column which are arranged from top to bottom, the positioning column penetrates through the second positioning hole, a positioning ball head matched with the ball socket groove is arranged at the upper end of the positioning column, and the spring is sleeved on the spring positioning column and limited on the lower end face of the limiting block; the limiting block is limited on the lower end face of the sliding block base plate.
Furthermore, the diameter of the positioning column is at least 0.1mm smaller than the inner diameter of the second positioning hole.
Furthermore, guide angles are arranged on two sides of the lower end face of the sliding block.
The utility model has the beneficial effects that: according to the utility model, the lower die holder is provided with the finish-machined positioning hole, the elastic positioning piece is arranged in the positioning hole, the sliding block base plate is also provided with the positioning hole, and the lower end face of the sliding block is provided with the ball socket groove to match the positioning of the sliding block during sliding.
The utility model will be explained in more detail below with reference to the drawings and examples.
Drawings
FIG. 1 is a cross-sectional view of a side core-pulling positioning structure of a mold according to the present invention.
Fig. 2 is a positioning schematic diagram of the structure of the present invention.
Fig. 3 shows a structure of a positioning member of the present invention.
Detailed Description
As shown in fig. 1 and 2, a mold side core pulling positioning structure is provided with a slider base plate 3 in a lower mold base 1, the slider 2 is arranged above the slider base plate 3, and a plurality of ball socket grooves 21 are arranged on the lower end face of the slider 2, and is characterized in that a first positioning hole 11 is formed in the position of the lower mold base 1 corresponding to the ball socket grooves 21, a spring 4 and a positioning piece 5 are arranged in the positioning hole 11, a second positioning hole 31 is formed in the position of the slider base plate 3 corresponding to the first positioning hole 11, and the upper end of the positioning piece 5 penetrates through the second positioning hole 31 and is matched and positioned with the ball socket grooves 21.
Further, as shown in fig. 3, the positioning element 5 includes a positioning column 52, a limiting block 53 and a spring positioning column 54 arranged from top to bottom, the positioning column 52 passes through the second positioning hole 31, a positioning ball 51 adapted to the ball socket groove 21 is arranged at the upper end of the positioning column 52, and the spring 4 is sleeved on the spring positioning column 54 and limited at the lower end surface of the limiting block 53; the limiting block 53 is limited on the lower end face of the sliding block base plate 3.
Further, in order to ensure more accurate positioning, the diameter of the positioning post 52 is at least 0.1mm smaller than the inner diameter of the second positioning hole 31.
Further, in order to ensure that the slide block does not collide with the positioning ball 51 during sliding and damage the mold and the positioning member 5, guide angles 22 are arranged on two sides of the lower end surface of the slide block 2.
The working principle of the utility model is as follows: as shown in fig. 2, when the ball socket groove 21 of the slider 2 slides to the position of the second positioning hole 11 of the slider base plate 3, the positioning element 5 is under the action of elastic force, and the positioning ball 51 is clamped into the ball socket groove 21 to achieve accurate positioning; when the sliding block 2 continues to slide, the positioning ball 51 can be disengaged from the ball socket groove 21, and the sliding block 2 is unlocked.
