Description

Technical Field

[0001] The utility model belongs to the technical field of plastic handle casting, and particularly relates to a casting device for a plastic handle of a tool. Background Art

[0002] In the manufacturing process of the plastic handle of a tool, in order to have both a good grip and sufficient strength, a method of casting a mold core is usually adopted for production. When a part of the mold is higher than other parts, inserts can be made to reduce the height of the mold, thereby saving materials.

[0003] In the traditional technology, multiple rubber inserts are arranged on multiple product casting grooves on the mold core, and the multiple rubber inserts are integrally formed with a main body (as Figure 4 shown), that is to say, the multiple rubber inserts are of an integral structure, and are installed and disassembled as a whole. When facing large knives with different sizes, shapes and casting requirements, the integrally formed rubber insert structure limits its flexibility in the mold. When facing large knives with different casting requirements, this structure may not be able to be adjusted and replaced as needed, and the overall rubber insert structure cannot well adapt to the size and shape of the mold, thus affecting the accuracy and stability of casting. Summary of the Utility Model

[0004] In order to make up for the deficiencies of the prior art, the utility model provides a casting device for a plastic handle of a tool.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] A casting device for a plastic handle of a tool, comprising an upper mold core and a lower mold core. Product casting grooves are respectively formed on the upper mold core and the lower mold core. Embedding grooves are formed on the upper mold core and the lower mold core and located on the product casting grooves. Rubber inserts which are matched with the product casting grooves to cast and form the product handle and can be detachably replaced are embedded in the embedding grooves.

[0007] When the product mold is large, the rubber inserts are designed as independent models and are suitable for large knives. The separated structure can better adapt to the size and shape of the mold, and improve the accuracy and stability of casting. In addition, the separated rubber inserts can be more conveniently installed, disassembled and replaced, reducing the operation difficulty and cost.

[0008] Preferably, the rubber inserts are directly knocked into the embedding grooves or fixed by screws. The purpose of these two methods is to ensure that the rubber inserts are firmly fixed on the mold core and will not fall off during use, which is convenient for installation and disassembly and replacement.

[0009] Preferably, the rubber inserts are made of TPE or TPR materials, which have good wear resistance and corrosion resistance.

[0010] Compared with the prior art, the technical effects and advantages of the utility model are: the casting device of the plastic handle of the knife is an independent type, suitable for large knives, and can handle relatively large product knife molds separately. It can be knocked in directly or fixed at the bottom of the glue without screws. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] 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.

[0017] The following is combined with Figures 1-3 To further explain this application in detail,

[0018] The embodiment of the present application discloses a casting device for a plastic handle of a knife, comprising an upper mold core 1 and a lower mold core 2, wherein a product casting groove 3 is respectively provided on the upper mold core 1 and the lower mold core 2, and an embedding groove 4 is provided on the upper mold core 1 and the lower mold core 2 and located on the product casting groove 3, wherein the embedding groove 4 is embedded with a detachable and replaceable glue insert 5 that cooperates with the product casting groove 3 to cast and mold the product handle 6. The glue insert 5 is made of TPE or TPR material. Since the glue insert 5 is made of special glue, it usually has good wear resistance and corrosion resistance, which can increase the service life of the mold.

[0019] In the casting device of the plastic handle, the glue insert 5 (an insert made of special glue) is embedded in the embedding groove 4 of the upper mold core 1 and the lower mold core 2, and cooperates with the product casting groove 3 for casting and molding the product handle 6. The embedding groove 4 is connected to the casting groove 3.

[0020] In addition, since the glue insert 5 is detachable and replaceable, when the mold wears or gets damaged, only the glue insert 5 needs to be replaced instead of the whole mold, reducing the maintenance cost and replacement cycle and increasing the flexibility of the mold.

[0021] The design of the glue insert 5 can be customized according to the specific requirements of the product handle 6 to ensure that the plastic can flow evenly and smoothly into the product pouring groove 3 during pouring, avoiding defects such as air bubbles and shrinkage cavities and improving the molding quality of the product.

[0022] When the product mold is large, the glue insert 5 is designed as an independent type and suitable for a large knife. The separated structure can better adapt to the size and shape of the mold, improving the accuracy and stability of pouring. In addition, the separated glue insert 5 can be more conveniently installed, disassembled and replaced, reducing the operation difficulty and cost.

[0023] Different product molds have different sizes, shapes and pouring requirements. By designing the glue insert 5 as an independent type and using it separately, it can be selected and replaced according to the specific product mold requirements, improving the applicability and flexibility of the mold. Since the glue insert 5 is detachable and replaceable, when a certain glue insert 5 wears or gets damaged, only that glue insert 5 needs to be replaced instead of the whole mold, reducing the maintenance cost and replacement cycle. In addition, the separately used glue insert 5 can be more conveniently cleaned, maintained and repaired, extending the service life of the mold. By optimizing the pouring effect and reducing the maintenance cost, using the independent and separated glue insert 5 can improve the production efficiency. This can not only reduce the downtime and scrap rate during the production process, but also improve the quality and consistency of the product.

[0024] The said glue insert 5 is directly knocked into the embedding groove 4 or fixed by screws.

[0025] The glue insert 5 can be directly knocked into the mold core or fixed with screws at the bottom of the glue. The purpose of both methods is to ensure that the glue insert 5 is firmly fixed on the mold core and will not fall off during use. The knocking method can use tools to insert the glue insert 5 into the groove of the mold core to make it closely adhere to the mold core. For the method of fixing by screws, holes need to be pre-drilled at the bottom of the glue and then the glue and the mold core are fixed together with screws.

[0026] One corresponding corner of the upper mold core 1 and the lower mold core 2 is provided with a notch 8, which is convenient to open the upper mold core or the lower mold core 2 through the notch 8 to clean the mold or perform maintenance.

[0027] The pouring device for the plastic handle of this tool uses an independent type of rubber inlay 5, that is, each rubber inlay 5 is an independent detachable component. Then it can be customized according to the specific size and shape of the mold, and can be replaced and repaired separately. This design not only improves the flexibility and adaptability of the mold, but also reduces the cost and maintenance difficulty, thus improving the accuracy and stability of pouring. Therefore, when facing large knives with different sizes, shapes and pouring requirements, the independent type of rubber inlay 5 has more advantages than the integrally formed rubber inlay 5 structure.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
