Embodiment Construction
[0021] see Figure 2 to Figure 7 As shown, the multi-directional core-pulling and locking joint mold of the present invention includes a movable mold core 10, a movable mold frame 20, a fixed mold core 30, a fixed mold frame 40 and a core-pulling device 50, and the movable mold frame 20 is surrounded by The outer edge of the movable mold kernel 10, the fixed mold frame 40 is surrounded by the outer edge of the fixed mold kernel 30. The movable mold core 10 and the fixed mold core 30 are fastened together to form a cavity 60, and the cavity 60 has first core-pulling holes 601 and second core-pulling holes 602 distributed in different directions. In this embodiment, the The included angle between the axial direction of the first core-pulling hole 601 and the axial direction of the second core-pulling hole 602 is an acute angle.
[0022] The core pulling device 50 includes a first slider seat 1, a first slant bar 2, a first slider core 3, a first locking block 4, a second slider...

The invention provides a multi-directional core-pulling locking mold. The multi-directional core-pulling locking mold comprises a movable mold core, a movable mold frame, a fixed mold core, a fixed mold frame and a core-pulling device. The movable mold core and the fixed mold core are buckled to form a cavity. A first core-pulling hole and a second core-pulling hole distributed in different directions are formed in the cavity. The movable mold frame is arranged on the outer edge of the movable mold core in a surrounding mode. The fixed mold frame is arranged on the outer edge of the fixed moldcore in a surrounding mode. The core-pulling device comprises a first sliding block seat, a first inclined rod, a first sliding block core, a first locking block, a second sliding block seat, a second inclined rod, a second sliding block core and a second locking block. When the mold is closed, the first inclined rod drive the first sliding block seat and the first sliding block core to move, thefirst sliding block core compacts a cavity surface of the first core-pulling hole under the action of the first locking block, and the second sliding block core compacts a cavity surface of the second core-pulling hole under the action of the second locking block, so that materials are efficiently prevented from flying.
Description
technical field [0001] The invention relates to a mould, in particular to a mould, which requires multi-directional core pulling and prevents the problem of flying materials. Background technique [0002] Such as figure 1 As shown, it is a metal base for auto parts, which is characterized by multiple holes, and the holes are relatively close to each other and the directions are inconsistent and not on the same plane, such as hole A and hole B. If the demoulding and core-pulling scheme of the existing mold is often unable to demould at one time, a core-pulling device can only be installed in the direction of hole A and hole B, and the demoulding is performed twice in sequence, which increases the demoulding time and workload. The production efficiency will be reduced, the tonnage of the mold will be increased, and the cost will be increased. Moreover, the contact between the slider core and the cavity surface in the core pulling device is not close, which will inevitably cau...
