Low-energy-consumption mold pressing mechanism of cap making machine

Abstract

The invention provides a low-energy-consumption mold pressing mechanism of a cap making machine, which comprises a lifting executing mechanism and a mounting supporting plate; an output end of the lifting executing mechanism is connected with the lower end face of the mounting supporting plate, and a pair of lower mold bases are mounted on the upper end face of the mounting supporting plate; one lifting executing mechanism lifts the two lower mold bases to be matched with two corresponding upper mold bases to achieve one-time production of two bottle caps, and under the condition of the same productivity, the lifting speed of the lifting executing mechanism is 1 / 2 of the original lifting speed; and the flash problem caused by upward jumping of shots when the speed of the lifting executingmechanism is increased is effectively solved, high-speed impact on a cap making mold is relieved, the service life is prolonged, and meanwhile the manufacturing cost is saved.

Description

technical field [0001] The invention relates to the technical field of cap molding and pressing machines, in particular to a molding mechanism of a cap making machine with low energy consumption. Background technique [0002] There are various machines and equipment for manufacturing plastic bottle caps, among which the molded capping machine is the most commonly used. The current cap molding and pressing machines all have a pressing module, which includes a rotating main body and a predetermined number of cap making molds arranged on the rotating main body for compression molding. [0003] In the prior art, the lid making mold includes an upper mold base and a lower mold base, and the upper mold base and the lower mold base are installed on the rotating main body to rotate together, such as figure 1 As shown, each of the lower mold bases 6 is correspondingly provided with a lifting actuator 2' that lifts it up and down, an upper model surface of the upper mold base is a co...

[0003] In the prior art, the lid making mold includes an upper mold base and a lower mold base, and the upper mold base and the lower mold base are installed on the rotating main body to rotate together, such as figure 1 As shown, each of the lower mold bases 6 is correspondingly provided with a lifting actuator 2' that lifts it up and down, an upper mold surface of the upper mold base is a convex surface, and a lower mold surface of the lower mold base It is a concave surface, and the lifting actuator 2' only lifts one of the lower mold bases 6 at a time and can only produce one bottle cap once it cooperates with the corresponding upper mold base, and its production capacity is relatively low. Usually, the production capacity can be ensured by shortening the lifting and lowering time of the lifting actuator 2' to lift the lower mold base 6, but in this case, shortening the time must increase the lifting speed of the lifting actuator, resulting in When the lower mold base 6 speeds up and rises, the pellets placed in the lower mold surface for preparing bottle caps jump up. The upper mold base makes the mold easily damaged
