Abstract
An injection mold includes a first mold part (10), a second mold part (50) mating with the first mold part, a sliding block (20), a cam actuator (30), and a rack (40). The sliding block is movably disposed on the first mold part. The cam actuators resist the sliding block for driving the sliding block to move along the first mold part. The rack is fixed to the second mold part for actuating the cam actuator.
Claims20
An injection mold, comprising:
- a first mold part;
- a second mold part mating with the first mold part;
- a sliding block movably disposed on the first mold part said sliding block forming a mold cavity with the first and second mold parts;
- a rotary cam actuator on the first mold part resisting the sliding block for driving the sliding block to move along the first mold part;
- and
- a rack fixed to the second mold part and configured for actuating the cam actuator to move the sliding block when the first mold part and the second mold part move relative to each other.

An injection mold, comprising:
- a first mold member having a mold core disposed thereon;
- a second mold member having a recessed portion positioned corresponding to the mold core, the second mold member coupled to the first mold member in a manner so as to allow their separation along a first axis;
- a sliding block disposed between the first mold member and the second mold member and being movable along a second axis distinct from the first axis, a mold cavity being defined between the first mold member, the second mold member and the sliding block;
- and
- a driving assembly including a first driving part fixed to the first mold member and a second driving part fixed to the second mold member;
- wherein the first driving part has a gear portion and a rotary cam portion, the second driving part engages with the gear portion in a manner so as to drive a corresponding one of the first driving part, the cam portion resists the sliding block in a manner so as to drive the sliding block to move along the second axis when the first and second mold members move relative to each other along the first axis.
