The specific embodiment
The utility model embodiment provides a kind of rotation core-pulling mechanism of injection mold, solved the loose core problem of inner back-off of horizontal plane, improved the production efficiency of injection mold, and the manufacturing cost of further having saved mould.
Be described in detail below in conjunction with the rotation core-pulling mechanism of accompanying drawing the utility model embodiment injection mold.
The utility model embodiment provides a kind of rotation core-pulling mechanism of injection mold, as shown in Figure 1, this rotation core-pulling mechanism comprises: rotary slider 1, and be arranged on described rotary slider 1 both sides, be used to drive the gear rotating mechanism 2 that described rotary slider 1 rotates, described gear rotating mechanism 2 is fixedlyed connected with the top board on the mould solid plate, described gear rotating mechanism 2 comprises fixed part 21 and rotary part 22, described rotary slider 1 is fixedlyed connected with described rotary part 22, wherein, the structure of rotary slider 1 as shown in Figure 2.
In the technical scheme of present embodiment, the version and the operating principle of loosing core by change, utilize the rotation of the rotary part of gear rotating mechanism, the driven rotary slide block rotates, thereby can from the back-off of product, deviate from smoothly, resetting of having avoided loose core of oil cylinder to loose core causing do not damaged on earth or injection cycle length waits some potential problems, and improved mold injection production efficiency, save the manufacturing cost of mould greatly, solved the loose core problem of inner back-off of loose core of oil cylinder structure insurmountable horizontal plane.
Further, described fixed part 21 can comprise: the tooth bar fixed block assembly 211 of fixedlying connected with described top board, and the tooth bar 212 of fixedlying connected with described tooth bar fixed block assembly 211, the structure of tooth bar 212 as shown in Figure 3.
Further, described tooth bar fixed block assembly 211 can be fixedlyed connected with top board in several ways, in the present embodiment, preferably adopts straight pin 213 fixedly connected.
Further, the function of this rotary part 22 can be realized by gear 221, as shown in Figure 4, then this rotary part 22 comprises: gear 221, described gear 221 is meshed with described tooth bar 212, and gear 221 matches with tooth bar 212 and drives rotary slider 1, makes rotary slider 1 stability of rotation, effectively avoided having guaranteed the yield of product after the demoulding because of rotating the damage that transition causes.
Further, this rotation core-pulling mechanism also comprises: slide block contiguous block assembly 3, and described slide block contiguous block assembly 3 is fixedlyed connected with the axle of described gear, and fixedlys connected with described rotary slider 1, and the structure of slide block contiguous block assembly 3 is as shown in Figure 5.
Further, this rotation core-pulling mechanism also comprises: slide block latch segment assembly 4, described slide block latch segment assembly 4 is fixed on the described top board, and be connected with 1 contact of described rotary slider, the structure of slide block latch segment assembly 4 as shown in Figure 6, wherein, slide block latch segment assembly 4 fits tightly with rotary slider 1 contacted contact-making surface and rotary slider 1, to prevent that in injection moulding process the rotary slider 1 that causes owing to powerful injection moulding power is shifted, thereby has guaranteed the product yield.
