The utility model discloses a drinking water packaging bottle production mold convenient to demold, and belongs to the technical field of drinking water packaging bottle production equipment. The drinking water packaging bottle production mold convenient to demold mainly comprises a mounting base body, an injection mold and a demolding mechanism. Wherein a mounting chamber is formed in the mounting base body, grooves are symmetrically formed in the two sides of the top end of the mounting base body in the width direction, the grooves are communicated with the mounting chamber, sliding grooves are symmetrically formed in the two sides of the bottom wall of the mounting chamber and correspond to the grooves, and two injection molds are transversely arranged above the grooves in the length direction; a demolding mechanism is connected to the sliding groove in a sliding mode, and the top end of the demolding mechanism is connected with the bottom end of the injection mold; a first driving piece and a second driving piece are arranged in the demolding mechanism. Compared with the prior art, the demolding effect of the packaging bottle is enhanced, the manual operation intensity is reduced, and the working efficiency is improved to a certain extent, so that the demolding device has higher practicability.

The utility model discloses a model device for gear production, which relates to the technical field of gear production and comprises a lower die, a temperature detector is fixedly mounted on one side of the lower die, a gas cap device is arranged in the lower die, an air inlet pipe is fixedly mounted on the other side of the lower die, and a gas outlet pipe is mounted on the other side of the lower die. And a control valve is fixedly mounted in the middle of the air inlet pipe, a heating pipe is fixedly mounted at the top of the interior of the lower mold, and a heating device is fixedly mounted on one side of the heating pipe. According to the model device for gear production, an upper mold is pushed by an electric push rod to slide downwards on the outer side of a supporting rod through a sliding ring, so that the upper mold is driven to move downwards, the upper mold and a lower mold are attached, injection molding is conducted through an injection molding pipe, and before injection molding, liquid in a heating pipe is driven to be circularly heated through operation of a heating device; therefore, heating treatment of the lower mold is achieved, and the problem that due to the fact that the temperature of the lower mold is too high and the injection molding hole is small, the injection molding hole is solidified and blocked is solved.
