Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
171 words
An injection molding machine for working with thermoplastic masses, comprising a. a stand, b. a stationary mold carrier stationarily mounted on the stand, c. a thrust plate mounted on the stand, d. a plurality of columns extending between the thrust plate and the stationary mold carrier, e. a displaceable mold carrier slidably mounted on the columns, f. a support movable with respect to the stationary mold carrier and having an aperture, g. a working member for moving the displaceable mold carrier with respect to the stationary mold carrier, h. an elongated spacer extending from the displaceable mold carrier toward the support and movable through the aperture in the support as the displaceable mold carrier approaches the support, i. a pressure member mounted on the support and movable across the aperture of the support to control passage of the spacer through the aperture, the pressure member being adapted to exert pressure on the spacer, and j. an adjusting element adapted to set the distance between the support and the displaceable mold carrier.
Claim 2
Dependent Claim
171 words

Claim 3
Dependent Claim
27 words
An injection molding machine as recited in claim 1, wherein the adjusting means includes a cylindrical spindle having an axial bore through which the spacer may pass.
Claim 4
Dependent Claim
49 words
An injection molding machine as recited in claim 1, wherein the thrust plate is stationary with respect to the stationary mold carrier and the adjusting means includes a threaded nut and threaded spindle, the nut being mounted in the thrust plate and the spindle being connected to the support.
Claim 5
Dependent Claim
39 words
An injection molding machine as recited in claim 1, wherein the thrust plate and the support are the same element and the adjusting means includes a threaded portion on the columns and a threaded nut on the thrust plate.
