Description

Technical Field

[0001] This utility model relates to the field of plastic mold technology, and in particular to a mold structure that can easily adapt to the replacement of multiple products. Background Technology

[0002] In the plastic mold industry, products often exist in multiple versions due to different functions, but the differences between these versions are usually not significant. To reduce costs, the industry commonly adopts the method of designing interchangeable inserts within a single mold, thereby enabling the production of different versions of products using the same mold. These interchangeable inserts can be directly replaced on the machine, effectively saving time and improving production efficiency. However, when dealing with products of different shapes, simply interchangeing some small inserts is insufficient because the ejector pin and water distribution system settings may be inconsistent, thus requiring modifications. Utility Model Content

[0003] The purpose of this utility model is to provide a mold structure that can easily adapt to the changing of multiple products. The mold core, inner mold ejector plate, and ejector pins are integrated into a whole. Different products have different inner mold components. The water supply is directly connected to the mold temperature controller from the inner mold. Different water supply systems can be designed according to the product shape. When changing products, only these integrated components need to be interchanged. There is no need to make complex adjustments and reassemble the mold, which greatly shortens the time required for changing products. At the same time, the ejector plate of the inner mold is pushed by the push rod to realize the ejection of the product. The inner mold ejector plate is effectively reset by spring, thereby realizing automatic production and has strong practicality.

[0004] To achieve the above objectives, the following technical solution is adopted:

[0005] A mold structure adaptable to easy product replacement includes a mounting base plate, a square iron plate mounted on the mounting base plate, and a mold base mounted on the square iron plate. A first base plate is mounted on the mounting base plate, and a first ejector plate is also arranged on the first base plate. A first push rod is also mounted on the first ejector plate. The structure also includes an inner mold assembly detachably mounted within the mold base. The inner mold assembly includes a mold core, an inner mold base plate, and an inner mold ejector plate. The mold core is mounted within the mold base, and a cavity for forming the product is formed on the mold core. The inner mold base plate is arranged below the mold core and connected to the first push rod. The inner mold ejector plate is mounted on the inner mold base plate, and a first ejector pin is also mounted on the inner mold ejector plate. One end of the first ejector pin is movably inserted into the cavity.

[0006] Furthermore, a pull rod is also installed on the inner mold ejector plate; a first limiting groove is provided on the top of the mold core, and a second limiting groove is provided on the bottom of the mold core corresponding to the first limiting groove; a first insertion hole is also provided at the bottom of the first limiting groove, which extends into the second limiting groove; the upper part of the pull rod moves through the first insertion hole and then moves into the first limiting groove; a limiting block is also installed on the top of the pull rod.

[0007] Furthermore, a spring is also fitted on the outer wall of the pull rod; one end of the spring is connected to the top of the inner mold ejector plate, and the other end of the spring is inserted into the second limiting groove.

[0008] Furthermore, it also includes a push rod connected to the first ejector plate.

[0009] Furthermore, a first ejector block is also installed on the inner mold ejector plate.

[0010] By adopting the above solution, the beneficial effects of this utility model are:

[0011] This invention integrates the mold core, inner mold ejector plate, and ejector pins into a single unit. Different products have different inner mold components. The water supply is directly connected to the mold temperature controller from the inner mold. This allows for the design of different water supply systems based on the product shape. When changing products, only these integrated components need to be interchanged, eliminating the need for complex adjustments and reassemblies to the mold, thus greatly reducing the time required for product changes. At the same time, the ejector plate of the inner mold is pushed by a push rod to eject the product. The inner mold ejector plate is effectively reset by a spring, thereby achieving automated production and making it highly practical. Attached Figure Description
