Progress in technology of mold milling with coated profile tools
Doležel, Ondřej ; Bumbálek, Bohumil (referee) ; Píška, Miroslav (advisor)
This diploma thesis is involved in possible development of different types of milling molds coated with modern plows. The first part is devoted to an analysis of contemporary trends in forms production technology. The analysis includes the different types of machines and tools for making various kinds of molds and dies. Another part deals with design of dies for sheet metal shears. The thesis continues by design of the production procedure after heat treatment and finishing die by miling. For milling of die are designed miling tools, the NC program and the possible development of manufacturing the die using a new machining center and the possibility of production optimization. The penultimate point of the thesis is technical and economical evaluation of the direction of development and comparison of positives and negatoves of each method. At the final evaluation is all summed up.

Machining of vulcanizing molds from aluminum alloys
Kaška, Zdeněk ; Kalivoda, Milan (referee) ; Polzer, Aleš (advisor)
This diploma thesis is focused on the issue of deep drilling of vulcanization molds from various aluminum alloys. The work will describe a brief description of machined materials and tools for deep drilling, including the production of the vulcanization mold itself. Based on experimental measurements, the analysis of data and knowledge gained from deep drilling of aluminum alloys with different silicon contents will be performed. In the end, the individual components of force loads for both machined materials will be compared

Design of technology for a mould manufacturing for casting in short run production
Pivoda, Miroslav ; Dvořáček, Jan (referee) ; Sedlák, Josef (advisor)
The aim of thesis is to describe the basic methods called Rapid Prototyping in theory and using one of them to create master model. Master model will be used to create silicone mould where a limited series of wax models will be by means of vacuum casting chamber. They will also be used to make ceramic form in which the final pad will be cast from freely accessible materials. After processing it the suitability of the proposed technologies for the production of the part in question will be assessed.

Production of the mold plunger
Rosa, Jakub ; Chladil, Josef (referee) ; Osička, Karel (advisor)
The meaning of the diploma thesis is to create a new mold plunger for injection mold using a suitable method according to the original mold plunger. The final mold part should meet the required surface parameters. The work is focused on the analysis of the original mold plunger and the experimental verification of suitable methods of production of the equivalent mold plunger.

Construction of molds for rubber molding
Bátrla, Martin ; Nohál, Libor (referee) ; Brandejs, Jan (advisor)
This Bachelor’s thesis contains the general body of knowledge related to theory of injection molds for rubber molding. There is also described a designing procedure of mold for rubber cuff which will be used as a protection against the dust and other impurities. The output is a 3D model of injection mold made in SolidWorks 2015 and 2D documentation of chosen parts.
