Embodiment Construction
[0010] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0011] This example figure 1 as shown,
[0012] A die set, which includes a body 1, the body 1 is a stepped cylinder, the upper end of the body 1 is a die port 2, the lower part of the die port 2 is a transition part 3, the The diameter of the transition part 3 is greater than the diameter of the die port 2, the lower part of the transition part 3 is provided with a sleeve part 4, and the die port 2 is provided with a stainless steel outer ring 5 and a tetrafluoroethylene inner ring 9, so A ring-mounted water tank 6 is arranged between the stainless steel outer ring 5 and the tetrafluoroethylene inner ring 9, and the die port 2 includes an annular die 7, and the die 7 is made of a titanium alloy material. The stainless steel outer ring 5 is fixed on the die 7 by screws, and ...

The invention provides a die sleeve. A body of the die sleeve is set as a step-like barrel, and the step shape can disperse stress so as to guarantee the rigidity of the body; meanwhile, an outer stainless steel ring and an inner tetrafluoroethylene ring are arranged at an end opening of an open die, and the surface smoothness of a pipe is greatly improved due to good lubrication and friction reduction performance of the outer stainless steel ring and the inner tetrafluoroethylene ring under the high-load condition; an annular water groove is formed between the outer stainless steel ring and the inner tetrafluoroethylene ring to cool the outer stainless steel ring, and accordingly, the service life is prolonged; the open die is made of a titanium alloy material and is resistant to friction and compression; the lower part of the end opening of the open die is a transition part, and the diameter of the transition part is larger than that of the end opening of the open die, thus the pressure inside the body is dispersed, and the body is prevented from being broken.
Description
technical field [0001] The invention relates to a mold cover. Background technique [0002] The mold sleeve is a mold structural part used to clamp the female mold or the male mold. The mold sleeve in the prior art is one of the common parts in plastic molds. Although it is widely used in plastic molds, it still has some shortcomings, such as unreasonable design, short practical life, and inconvenient installation and disassembly. Such problems still exist in most of the plastic molds. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a mold cover, the purpose of which is to provide a mold cover that is easy to disassemble and has a long service life. [0004] A die set, which includes a body, the body is a stepped cylinder, the upper end of the body is a die port, the lower part of the die port is a transition part, and the diameter of the transition part is larger than the mouth The diameter of ...
