Preferably, the slider is located the B board, be equipped with the guide block corresponding to every slider along axis circumference array distribution on the B board, be equipped with the spout that the cross-section is the type of falling T on the guide block, the slider bottom is spacing in the spout, and the spout direction is along radial direction, the direction of motion of the spacing slider of spout is along radial direction.

Preferably, still including the driving needle corresponding to every slider, be equipped with the slope guide way in the slider, the inclined plane upper end of slope guide way is close to the lower extreme apart from the axis, and ejector plate under the connection of driving needle bottom, the inclined plane of locating the vertical guide way contact chute on the B board is passed at the driving needle top.

Preferably, the mould also comprises a top roller, the bottom of the top roller is connected with an upper ejector plate, and the top of the top roller penetrates through the plate B and the lower mould core to contact with a product.

The sliding block mould unloading device has the advantages that the sliding blocks move along the radius direction in the moving direction, the circumferential movement of the sliding blocks is avoided, and all the sliding blocks distributed in the circumferential array do not move and interfere with each other when the sliding blocks move outwards along the radius direction and are demoulded.

Detailed Description

In order to make the present application more comprehensible, preferred embodiments accompanied with figures are described in detail below.

Examples

The embodiment provides a multi-direction slip structure of loosing core, be used for injection moulding to have the product of circumference array distribution back-off structure especially, as shown in fig. 2, as shown in fig. 3, including drive needle 1, slider 2, see fig. 3, slider 2 is a plurality of, distribute along axis circumference array, slider 2 is established to the shaping end towards the one end of axis, the shaping end forms the shaping chamber that is used for the shaping product structure with lower mould benevolence 3 cooperation, slider 2 is located B board 4, be provided with guide block 5 corresponding to every slider 2 along axis circumference array distribution on the B board 4, be provided with the spout that the cross-section is the type of falling T on the guide block 5, slider 2 bottom is spacing in the spout, the spout direction is along the direction of radius, the direction of motion of the spacing slider 2 of spout is along the direction of radius, avoid the circumferential motion of slider 2, make all sliders 2 that circumference array distributes all can not take place the motion when outwards moving along the direction of radius and interfere.
