Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold for making the mouthpiece of an electronic cigarette. Background Technology

[0002] Currently, molds are tools used to create shaped objects. These tools are composed of various different parts. Molds mainly achieve the processing of the shape of objects by changing the physical state of the material being molded, and are known as the "mother of industry".

[0003] Meanwhile, injection molds are tools for producing plastic products, and also tools for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used for mass production of certain complex-shaped parts. Specifically, it refers to injecting heated and molten plastic into the mold cavity under high pressure by an injection molding machine, and obtaining the molded product after cooling and solidification.

[0004] Existing molds for manufacturing e-cigarette mouthpieces can only provide cooling water channels for the outer surface of the mouthpiece, resulting in low cooling efficiency. Furthermore, the existing mouthpiece molds suffer from poor structural design, often only allowing the production of a single-sized inner bevel, leading to poor versatility and practicality.

[0005] Therefore, a new technical solution needs to be developed to address the above problems. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a mold for manufacturing the mouthpiece of an electronic cigarette, which greatly improves cooling efficiency and reduces the need for additional cooling water channels in the upper molding cavity, thereby significantly reducing processing costs.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A mold for manufacturing the mouthpiece of an electronic cigarette includes an upper mold assembly and a lower mold assembly connected to each other. The upper mold assembly includes an upper mold base, a first upper pad, a second upper pad, a forming upper mold, and an upper mold core embedded in the forming upper mold. The lower end of the upper mold core forms an upper forming cavity.

[0009] The lower mold assembly includes a lower mold base, a first lower pad, a forming lower mold, and a lower mold core adapted to the upper mold core. The lower mold base, the first lower pad, and the forming lower mold are arranged sequentially from bottom to top, and the lower mold core is embedded in the forming lower mold.

[0010] The lower mold core includes a first mold core, a second mold core, and a third mold core. The upper end face of the first mold core is recessed to form a first mounting cavity. The inner bottom wall of the first mounting cavity is formed to form a through hole. The second mold core is installed in the first mounting cavity. The upper end of the second mold core forms a lower forming cavity, which is connected to the through hole.

[0011] The lower end face of the first mold core is recessed upward to form a second mounting cavity with a through hole. The third mold core has a forming part. The third mold core is installed in the second mounting cavity and the forming part extends into the lower forming cavity through the through hole and then extends out of the first mold core. The interior of the third mold core is provided with a cooling water channel.

[0012] After the upper and lower molding molds are assembled together, the molding part extends into the upper molding cavity, and the upper molding cavity, the molding part, and the lower molding cavity together form the product cavity.

[0013] As a preferred embodiment, the molding part is detachably connected to a protrusion on its peripheral side within the lower molding cavity for molding the inner inclined surface of the cigarette holder.

[0014] As a preferred embodiment, a limiting member is slidably mounted on the inner side of the third mold core along the vertical direction, and the limiting member is detachably connected to the protrusion.

[0015] As a preferred embodiment, the third mold core is provided with an upwardly recessed groove, and the limiting member is slidably installed in the groove;

[0016] The molding part has a mounting hole with a connecting slide groove on its peripheral side inside the lower molding cavity. One end face of the protrusion has an inclined surface, and the other end is provided with a locking part. The peripheral side face of the locking part is recessed with a locking groove, and the locking groove has an extension entrance.

[0017] The protrusion is installed in the mounting hole, the inclined surface is located in the lower forming cavity, and the locking part and its locking groove are both located in the sliding groove.

[0018] The limiting member has a limiting protrusion. When the limiting member slides upward in the slide groove, the limiting protrusion slides in from the extension inlet and is limited in the locking groove.

[0019] As a preferred embodiment, a positioning groove is formed on the top of the slide, and a positioning part is also formed on the limiting member, the positioning part being adapted to the positioning groove.

[0020] As a preferred embodiment, the limiting member includes a connecting portion and a limiting block connected to the top of the connecting portion, wherein the limiting protrusion is formed on the limiting block.

[0021] As a preferred embodiment, the connecting part is detachably connected to the limiting block.

[0022] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly improves the cooling efficiency by setting a cooling water channel inside the third mold core. Moreover, the molding part is located in the upper molding cavity, which can reduce the need to set additional cooling water channels in the upper molding cavity and greatly reduce the processing cost.

[0023] Secondly, the detachable design of the bumps allows for the production of mouthpieces with different bevel sizes by replacing different bumps according to actual production needs. This results in good versatility and practicality, and low production costs.

[0024] Furthermore, the detachable structure of the limiting component facilitates its replacement and maintenance, making it highly practical.
