Abstract
Abstract A device with a shoulder having a supporting and fitting surface for chucking an insert such as a casting mold, especially a foaming mold as it is employed in connection with the foaming of synthetic materials. The device comprises a structure, e.g., a frame structure, with at least three first fitting surfaces which partially extend over second fitting surfaces formed by first rims of an insert and by second rims of holding strips. The insert is provided with third rims over which the holding strips extend.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
114 words
In combination, an insert having a top side therewith free of screws and problems of leakage associated with loosening thereof due to thermic changes, and a foam mold used during foaming of synthetic materials having first rims with first fitting surfaces, said mold being provided with a structure having at least three second fitting surfaces complementary with the insert, and a plurality of holding strips having second rims with third complementary fitting surfaces, said second fitting surfaces extending at least partially over said first fitting surfaces of said first rims, and over said third fitting surfaces of said holding strips, said insert also being provided with third rims having said holding strips extending thereover.
Claim 2
Dependent Claim
114 words
In combination, an insert having a top side therewith free of screws and problems of leakage associated with loosening thereof due to thermic changes, and a foam mold used during foaming of synthetic materials having first rims with first fitting surfaces, said mold being provided with a structure having at least three second fitting surfaces complementary with the insert, and a plurality of holding strips having second rims with third complementary fitting surfaces, said second fitting surfaces extending at least partially over said first fitting surfaces of said first rims, and over said third fitting surfaces of said holding strips, said insert also being provided with third rims having said holding strips extending thereover.
Claim 3
Dependent Claim
13 words
The combination according to claim 1, in which said structure is a frame.
Claim 4
Dependent Claim
94 words
The combination according to claim 1, in which said at least three second fitting surfaces are plane and form part of a four-corner frame having a top side surface and lateral outside surfaces, said at least three second fitting surfaces extending from said top side at a slant in the direction toward the adjacent lateral outside surface and in spaced relationship to said top side and below the latter merge with a supporting surface forming part of said frame and with said fitting surfaces forming an acute angle to thereby establish a dovetail-like connection.
Claim 5
Dependent Claim
24 words
The combination according to claim 1, in which said at least three second fitting surfaces and said first rims extend parallel to each other.
Claim 6
Dependent Claim
28 words
The combination according to claim 3, in which said supporting surface comprises recess means extending around said frame, and which includes sealing means arranged in said recess means.
Claim 7
Dependent Claim
17 words
The combination according to claim 5, in which said recess means is parallel to said supporting surface.
Claim 8
Dependent Claim
23 words
The combination according to claim 3, in which said holding strips extend at least approximately over the entire length of said supporting surface.
Claim 9
Dependent Claim
48 words
The combination according to claim 3, in which at least one of said holding strips has a parallelogram-shaped cross section having a top side flush with said top side surface of said frame and the top side of said insert, said holding strip resting on said supporting surface.
Claim 10
Dependent Claim
20 words
The combination according to claim 1, in which at least one of said holding strips has a round cross section.
Claim 11
Dependent Claim
41 words
The combination according to claim 3, in which said structure has two relatively short and two relatively long sides, and in which one of said holding strips has a trapezoidal longitudinal section and is located at one of said narrow sides.
Claim 12
Dependent Claim
101 words
The combination according to claim 3, in which one of said holding strips has one end located within the region of the other one of said holding strips, and in which one of said second fitting surfaces extends parallel to said other one of said holding strips, said one end of said one holding strip engaging said one of said second fitting surfaces, the other end of said one of said holding strips extending perpendicularly with regard to said supporting surface, and the upper edge of said last mentioned one of said holding strips engaging the upper edge of said structure.
Claim 13
Dependent Claim
42 words
The combination according to claim 10, in which one of said holding strips extends along one of the relatively long sides of said structure and has a longitudinal side section projecting beyond said insert in positive engagement with another adjacent holding strip.
Claim 14
Dependent Claim
50 words
The combination according to claim 12, which includes connecting means, and in which said one holding strip is at the longitudinal side of said structure within the region of its free end fixedly connected to said structure by means of said connecting means accessible from the outside of said structure.
Claim 15
Dependent Claim
34 words
The combination according to claim 8, in which the top side of at least one of said holding strips is provided with means for lifting said last mentioned holding strip out of said structure.
