[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A glass molding mold for easy demolding includes two mold bodies 1. Each mold body 1 has a mold cavity on one side opposite to the other. The top of the mold cavity is inclined. Each mold body 1 has a filling port on one side opposite to the other and near the top. A slide groove is provided inside the mold body 1 near the bottom. A slider 5 is slidably connected to the inner wall of the slide groove to drive the ejector pin 2 to rise and fall. Both ends of the slider 5 have arc grooves. A ball bearing 11 is rolledly connected to the inner wall of the arc groove to reduce the resistance when the slider 5 moves. Part of the ball bearing 11 passes through the arc groove. A vertically arranged ejector pin 2 is fixedly connected to the upper end of the slider 5 to eject the product. The top of the slide groove has an opening communicating with the mold cavity. The upper end of the ejector pin 2 slides into the opening.

[0022] In this embodiment, four rectangular guide rods 3 are slidably inserted into the upper end of the slider 5 to guide the slider 5 in raising and lowering. The upper end of the guide rod 3 is fixedly connected to the inner top of the slide groove. A second fixing ring 12 is fixedly sleeved on the upper end of the guide rod 3 to improve the firmness of the upper end of the guide rod 3. The upper end of the second fixing ring 12 is fixedly connected to the inner top of the slide groove. The lower end of the guide rod 3 passes through the slider 5 and is fixedly connected to a support block 6 to support the slider 5. A rubber pad 10 is fixedly connected to the upper end of the support block 6 to prevent wear between the slider 5 and the support block 6. A spring 4 is slidably sleeved on the upper end of the guide rod 3 to pull the slider 5 up. The two ends of the spring 4 are fixedly connected to the upper end of the slider 5 and the inner top of the slide groove, respectively.

[0023] In this embodiment, a connecting rope 7 is fixedly connected to the lower end of the slider 5 to drive the slider 5 to move downward. The lower end of the connecting rope 7 is fixedly connected to the inner bottom of the slide groove. The connecting rope 7 is made of metal to improve strength. Both ends of the connecting rope 7 are fixedly sleeved with first fixing rings 9 to improve the firmness of the two ends of the pull rope 7. The opposite sides of the two first fixing rings 9 are fixedly connected to the lower end of the slider 5 and the inner bottom of the slide groove, respectively. The opposite sides of the two mold bodies 1 are fixedly connected with horizontally arranged push plates 8 to push the pull rope 7. The opposite sides of the two mold bodies 1 are provided with openings communicating with the slide groove. The two push plates 8 slide through the two openings and abut against the connecting rope 7.

[0024] In this embodiment, the material is injected into the mold cavity through the injection port. After the product is formed, the two mold bodies 1 separate, and each drives the two push plates 8 to detach from the slide. At this time, the four springs 4 pull the slider 5 upward by elasticity. The slider 5 then drives the top column 2 upward. The top column 2 applies an upward pushing force to the product in the mold cavity. Since the bottom of the product is pushed upward, the product moves out of the mold cavity. Considering that this is a mold suitable for glass bottle products, the top of the mold cavity is set at an angle. This design not only conforms to the shape of the glass bottle product, but also allows the product to slide outward when the bottom of the product is pushed upward, avoiding damage to the bottom of the product due to force. When the two mold bodies 1 close again, they will drive the push plates 8 to insert into the slide. The push plates 8 push the connecting rope 7 to move. The connecting rope 7 pulls the slider 5 down to reset. The slider 5 drives the top column 2 down to reset, thereby realizing the cyclic use of the top column 2.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
