The through hole of excessive sliding block, described drive mechanism are connected with small slide block, and during the demoulding, small slide block side is driven by described drive mechanism
To translation, and then small slide block drives stem lateral translation to be extracted out out of described big sliding block through hole.
Further improved as the utility model, described drive mechanism includes cylinder and pull bar, the head of described pull bar
Portion is T-shaped, and the afterbody of described small slide block is provided with the groove to match with the head of pull bar, and described rod head is connected to
On groove, described cylinder is connected with pull bar.
Further improved as the utility model, described slide block slot includes guide groove and mounting groove, described small slide block
Including the portion of sliding and head, the head of described small slide block is in mounting groove, and the portion of sliding of described small slide block is located at guiding
In groove, wear-resistant block is additionally provided with described guide groove, described wear-resistant block is located between small slide block and the side wall of big sliding block.
Compared with prior art, the utility model has the advantage of simple in construction, knockout course is smooth.In simple terms, produce
Product drive pull bar to drive small slide block to move during demoulding, by cylinder, and small slide block is by the stem being connected with product from big sliding block
On through hole extract out, realize the separation of stem and product, such product carry out the demoulding in next step can be more smooth.
