Description

Technical Field

[0001] This utility model belongs to the field of mold technology, and in particular relates to an improved bottle cap opening notch mold. Background Technology

[0002] Existing bottle caps have a notch at the bottom of the side wall, and their molding mold is as follows: Figure 1 and Figure 2 As shown, a forming protrusion 2 is set on the top of the push sleeve 1. The notch on the bottle cap is formed by the forming protrusion 2. When demolding, the bottle cap is pushed out of the mold by the ejector pin 3 set on the main core 4. Since the ejector pin 3 is set on the main core 4, it is impossible to set a cooling water channel, which results in high mold temperature and poor product shrinkage control.

[0003] Therefore, addressing the shortcomings of the existing technologies has become the focus of efforts for those working in this field. Utility Model Content

[0004] The purpose of this invention is to provide an improved bottle cap opening notch mold that can completely solve the shortcomings of the prior art.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An improved bottle cap opening notch mold includes a main core, a push sleeve is sleeved over the main core, an opening insert is provided on the outer wall of the main core, a forming protrusion is provided on the top of the opening insert, the forming protrusion extends upward out of the top surface of the push sleeve, and a cooling water channel is opened on the main core.

[0007] Preferably, the main core is provided with a limiting step, and the inner wall of the opening insert is provided with a corresponding mating step, and the opening insert is mated with the limiting step through the mating step.

[0008] Preferably, the outer wall of the main core is uniformly fitted with three inclined tops along the circumferential direction.

[0009] Preferably, the outer wall of the inclined top is provided with an installation step, and the bottom of the push sleeve cooperates with the installation step.

[0010] Preferably, the top of the push sleeve is provided with a mating hole, and the top of the opening insert is movably mated with the mating hole.

[0011] Preferably, the cooling water channel is a central blind hole opened from the bottom surface of the main core upwards.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the ejector pins on the main core are eliminated, thereby simplifying the mold structure and helping to reduce the mold manufacturing cost and manufacturing difficulty; cooling water channels are set on the main core, which helps to control the mold temperature and facilitates the control of product shrinkage.

[0016] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0017] like Figure 3 As shown, an improved bottle cap opening notch mold includes a main core 4, a push sleeve 1 sleeved on the main core 4, an opening insert 5 on the outer wall of the main core 4, a forming protrusion 2 on the top of the opening insert 5, a mating hole 6 on the top of the push sleeve 1, the top of the opening insert 5 movably mating with the mating hole 6, the forming protrusion 2 extending upward from the top surface of the push sleeve 1, and a cooling water channel 7 opened on the main core 4, the cooling water channel 7 being a central blind hole opened upward from the bottom surface of the main core 4.

[0018] In this embodiment, the main core 4 is provided with a limiting step 8, and the inner wall of the opening insert 5 is provided with a corresponding mating step. The opening insert 5 is mated with the limiting step 8 through the mating step.

[0019] The outer wall of the main core 4 is uniformly fitted with three inclined tops 9 along the circumference. The outer wall of the inclined tops 9 is provided with an installation step 10, and the bottom of the push sleeve 1 is fitted with the installation step 10.

[0020] This invention eliminates the ejector pin on the main core, thus simplifying the mold structure and reducing manufacturing costs and difficulty. Cooling water channels are provided on the main core, facilitating mold temperature control and minimizing product shrinkage. The opening insert for the opening notch on the molded bottle cap is integrated with the main core, unlike existing technologies where it's formed on the push-sleeve. This allows for easy demolding with just one push-sleeve ejection of the product.

[0021] Similarly, it should be understood that, in order to simplify this disclosure and aid in understanding one or more of the various aspects of the invention, in the above description of exemplary embodiments of the invention, various features of the invention are sometimes grouped together in a single embodiment, figure, or description thereof. However, this method of disclosure should not be interpreted as reflecting an intention that the claimed invention requires more features than are expressly recited in each claim. Rather, as reflected in the following claims, the inventive aspect lies in fewer than all features of a single foregoing disclosed embodiment. Therefore, the claims following the detailed description are hereby expressly incorporated into that detailed description, wherein each claim itself is a separate embodiment of the invention.

[0022] Those skilled in the art will understand that modules in the device of the embodiments can be adaptively changed and placed in one or more devices different from that embodiment. Modules, units, or components in the embodiments can be combined into a single module, unit, or component, and further, they can be divided into multiple sub-modules, sub-units, or sub-components. Except where at least some of such features and / or processes or units are mutually exclusive, any combination can be used to combine all features disclosed in this specification (including the accompanying claims, abstract, and drawings) and all processes or units of any method or device so disclosed. Unless expressly stated otherwise, each feature disclosed in this specification (including the accompanying claims, abstract, and drawings) may be replaced by an alternative feature that serves the same, equivalent, or similar purpose.

[0023] Furthermore, those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are meant to be within the scope of this invention and form different embodiments.

[0024] It should be noted that the above embodiments are illustrative of the present invention and not restrictive, and that those skilled in the art can devise alternative embodiments without departing from the scope of the appended claims.
