Description

Technical Field

[0001] The utility model relates to the technical field of beverage bottle blow molding molds, in particular to a beverage bottle production mold which is convenient for demoulding. Background Art

[0002] Most beverage bottles are plastic bottles, which can be made through blow molding. The preform that has been heated is placed in the mold, and the preform is blown up by high-pressure gas, which causes the preform to stretch rapidly and form in the mold cavity, thus being blown into a plastic bottle.

[0003] For example, the patent document with application number 202222075422.8 discloses a beverage bottle mold that is easy to demold. The utility model discloses a beverage bottle mold that is easy to demold, including a left mold assembly, a right mold assembly and a lifting assembly. The left mold assembly includes a left half mold, two left mold cavities opened on the inner side of the left half mold, a left conical convex point fixed in the middle of the inner sides of the two left mold cavities, and a slot opened on the inner side of the left half mold at the upper end of the left mold cavity. Two slots are opened at the upper end of each left mold cavity, and the slots are located on the inner side of the upper end of the left mold cavity. A semicircular channel connected to the left mold cavity is opened at the upper middle end of the inner side of the left half mold, and the edges and corners of the left conical convex point are slightly rounded. This beverage bottle mold that is easy to demold has a stopper needle whose length is greater than that of the bottom of the bottle, so that when the bottle is lifted up, the bottom of the bottle first contacts the stopper needle, and the lifting force is used to make the stopper needle block the lifting height of the bottle, so that the bottle is separated from the mold, thereby facilitating demolding of the beverage bottle. However, when using this beverage bottle mold that is easy to demold, a lifting rod needs to be used to assist in demolding, which may reduce the production speed in large-scale production.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a beverage bottle production mold that is convenient for demoulding is proposed. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-Figure 2 As shown, a beverage bottle production mold that is easy to demold, includes a left mold component 1, a slide groove 2 is opened at the lower end of the surface of the left mold component 1, and a spring base 201 is set at the bottom of the slide groove 2. The advantage of this arrangement is that the ejection direction of the spring piece 203 can be guaranteed by the setting of the slide groove 2.

[0020] Furthermore, a compression spring 202 is installed at the upper end of the spring base 201, and a spring sheet 203 is installed at the upper end of the compression spring 202, and the spring sheet 203 is slidably connected to the slide groove 2. The advantage of this arrangement is that, through the arrangement of the spring sheet 203, when the left mold assembly 1 and the right mold assembly 102 are fitted together, the baffle 204 can enter the interior of the slide groove 2 to prevent the spring sheet 203 from popping out and affecting the blow molding effect of the beverage bottle. At the same time, when the right mold assembly 102 is opened, the spring sheet 203 pops out to push the molded beverage bottle to prevent it from adhering to the surface of the mold, while increasing the blow molding speed of the plastic bottle.

[0021] Furthermore, a right mold component 102 is provided at the front end of the left mold component 1, and a baffle 204 is provided on the lower surface of the front end of the right mold component 102. The advantage of this arrangement is that the slide groove 2 can be blocked by the setting of the baffle 204 to ensure the smoothness of the inside of the mold.

[0022] Furthermore, a plug hole 101 is provided on the surface of the left mold component 1, and an insertion rod 103 is provided on the surface of the right mold component 102, and the left mold component 1 and the right mold component 102 are plug-connected by the insertion rod 103. This setting is an existing device and will not be described in detail.

[0023] Furthermore, a cooling groove 3 is provided on one side of the front end surface of the left mold assembly 1, and a stopper 301 is provided on one side of the front end surface of the right mold assembly 102, and the stopper 301 and the cooling groove 3 are fitted together. The advantage of this arrangement is that, through the arrangement of the cooling groove 3, after the right mold assembly 102 is opened, cold air can be blown along the cooling groove 3 to the inside of the left mold assembly 1 to cool the beverage bottle inside.

[0024] like Figure 3As shown, a cooling groove 302 is provided on the rear end surface of the left mold assembly 1, and the shape of the cooling groove 302 is U-shaped. A cooling pipe 303 is installed inside the cooling groove 302, and the material of the cooling pipe 303 is made of pure copper. The advantage of this arrangement is that the heat of the mold can be quickly taken away by the arrangement of the cooling pipe 303, thereby avoiding overheating of the mold due to long-term use and affecting the effect of blow molding.

[0025] Working principle: When using the beverage bottle production mold with convenient demolding, first, after the left mold component 1 and the right mold component 102 are attached by the insertion rod 103, the baffle 204 is inserted into the inside of the slide groove 2 to block the slide groove 2. After the beverage bottle is blow-molded, the mold is opened, the baffle 204 leaves the slide groove 2, and the cold air is passed through the cooling groove 3 to cool the plastic bottle inside the mold. After the baffle 204 on the right mold component 102 releases the restriction on the spring 203, the compression spring 202 drives the spring 203 to pop out along the slide groove 2, and the beverage bottle inside is popped out to complete the blow molding. This is the working principle of the beverage bottle production mold with convenient demolding.
