Abstract

A mold assembly for insert-molding a heterogeneous object includes an upper mold and a lower mold. The upper mold includes a cavity for accommodating an insert object. The lower mold includes a rigid body and a resilient contact member for resting the insert object. The resilient contact member absorbs dimensional variations of the insert object during the insert molding process.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A mold assembly, comprising:
 an upper mold comprising a first rigid body and a first resilient contact member; and   a lower mold comprising a second rigid body and a second resilient contact member, wherein the upper mold and the lower mold, when combined together, define an inner space for accommodating an insert object, wherein the insert object contacts both the first resilient contact member and the second resilient contact member, thereby absorbing dimensional variations of the insert object.   
     
     
         2 . The mold assembly according to  claim 1 , wherein the first resilient contact member is fixed on an inner side of the first rigid body. 
     
     
         3 . The mold assembly according to  claim 1 , wherein the second resilient contact member is fixed on an inner side of the second rigid body. 
     
     
         4 . The mold assembly according to  claim 1 , wherein a polymer elastomer, which is injected into the inner spacer, bonds with the insert object to form the heterogeneous object. 
     
     
         5 . The mold assembly according to  claim 4 , wherein the polymer elastomer is composed of a material that is different from the first and the second resilient contact members. 
     
     
         6 . The mold assembly according to  claim 5 , wherein the polymer elastomer is composed of silica gel and the first and the second resilient contact members are composed of synthetic rubbers. 
     
     
         7 . The mold assembly according to  claim 5 , wherein the polymer elastomer is composed of a synthetic rubber and the first and the second resilient contact members are composed of silica gels. 
     
     
         8 . The mold assembly according to  claim 1 , wherein the insert object does not contact the rigid body. 
     
     
         9 . The mold assembly according to  claim 1 , wherein the insert object comprises metal, plastic, ceramic or glass.
