Here's the IIHF Rule Book (Goalie Interference starts on page 129): https://blob.iihf.com/iihf-media/iih...lebook_v22.pdf

69.3. CONTACT INSIDE THE GOAL CREASE

If an attacking Player initiates "a relevant contact" with a Goalkeeper, incidental or otherwise, while the Goalkeeper is in their Goal Crease, and a goal is scored, the goal will be disallowed.

If a Goalkeeper, in the “act of establishing their position” within their Goal Crease, initiates contact with an attacking Player who is in the Goal Crease, and this results in an impairment of the Goalkeeper’s ability to defend their goal, and a goal is scored, the goal will be disallowed.

If, after any contact by a Goalkeeper who is attempting to establish position in their Goal Crease, the attacking Player does not immediately vacate their current position in the Goal Crease (i.e., give ground to the Goalkeeper), and a goal is scored, the goal will be disallowed. In all such cases, whether or not a goal is scored, the attacking Player will receive the appropriate penalty for Goalkeeper “interference”.

If an attacking Player establishes a “significant position” within the Goal Crease, so as to obstruct the Goalkeeper’s vision and impair their ability to defend their goal, and a goal is scored, the goal will be disallowed.

For this purpose, a Player “establishes a significant position within the crease” when, in the Referee’s judgment, their body, or a substantial portion thereof, is within the Goal Crease for more than an instantaneous period of time.

The only defence is the argument that he was pushed into the crease by the d-man. Even then, the contact with the defender is significantly separate from the contact with the goalie. Getting pushed into the crease doesn't then give you free rein to do whatever you want inside the crease.

If an attacking Player has been pushed, shoved, or fouled by a defending Player so as to cause them to come into contact with the Goalkeeper, such contact will not be deemed contact initiated by the attacking Player for purposes of this rule, provided the attacking Player has made a reasonable effort to avoid such contact
