Description

Technical Field

[0001] The utility model relates to the field related to rubber ring processing, in particular to an O-type rubber ring mold. Background Art

[0002] A mold is a tool used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the object's shape by changing the physical state of the molded material. The mold generally consists of two parts: a movable mold and a fixed mold (or a punch and a die). The two parts can be separated and combined. When separated, the workpiece is taken out, and when closed, the blank is injected into the mold cavity for forming. The O-ring mold is used to process O-rings.

[0003] The existing technology still has certain deficiencies in the use of O-ring rubber molds. The mold cavity and mold base in the traditional mold are usually an integrated structure. Since the molded O-rings are embedded in the mold cavity, they need to be taken out one by one during demolding. Not only does the unloading time take a long time, but it is also inconvenient to clean the residual rubber material in the mold cavity. Utility Model Content

[0004] The purpose of the present utility model is to provide an O-type rubber ring mold to solve the problem proposed in the above background technology that the mold cavity and the mold base in the traditional mold are usually an integrated structure. Since the molded O-type rubber rings are embedded in the mold cavity, they need to be taken out one by one during demolding, which not only takes a long time to unload, but also makes it inconvenient to clean the rubber material remaining in the mold cavity.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an O-shaped rubber ring mold, comprising an O-shaped rubber ring mold base, a lower mold base is provided above the O-shaped rubber ring mold base, a jacking adjustment groove is provided below the interior of the lower mold base, a balancing lifting plate is provided inside the jacking adjustment groove, a support rod is provided above the balancing lifting plate, a jacking unloading block is provided on the top of the support rod, a lower O-shaped mold cavity is provided on the top of the jacking unloading block, the jacking unloading block is provided inside the slot, and the slot is provided on the surface of the lower mold base, cylinders are provided on both sides of the interior of the O-shaped rubber ring mold base, an upper mold base is provided above the lower mold base, an upper O-shaped mold cavity is provided inside the upper mold base, and an opening and closing handle is provided at one end of the upper mold base.

[0006] In a further embodiment, both ends of the bottom surface of the lower mold base are fixedly connected to the O-ring mold base through a first fixing bolt, and the cylinder is fixedly connected to the O-ring mold base through a second fixing bolt.

[0007] In a further embodiment, the lifting and unloading block is connected to the notch by sliding, a sealing ring is provided above the outside of the support rod, and the support rod and the lifting and unloading block are configured as an integral structure.

[0008] In a further embodiment, the bottom of the support rod is fixedly connected to the balance lifting plate by fixing screws, and the balance lifting plate and the top of the lifting adjustment slot are slidably connected through guide columns and guide holes.

[0009] In a further embodiment, a telescopic rod is provided inside the cylinder, and the top end of the telescopic rod is connected to the balance lifting plate through an assembly plate and an assembly slot, and the assembly plate and the assembly slot are fixedly connected by screws.

[0010] In a further embodiment, the other end of the upper mold base is hingedly connected to the lower mold base through a flip hinge, and both sides of the bottom surface of the upper mold base are connected to the lower mold base through positioning strips and positioning slots.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. In the utility model, the lower O-shaped mold cavity and the lifting and unloading block are set as an integrated structure. The lower O-shaped mold cavity can be uniformly pushed upward by the lifting and unloading block, so that the formed O-shaped rubber ring is higher than the lower mold base, and the lower O-shaped mold cavity is separated from the lower mold base. This not only expands the visual range, but also makes it easier to take out the O-shaped rubber ring, saves unloading time, increases the cleaning space around the lower O-shaped mold cavity, and makes it easier to clean the interior of the lower O-shaped mold cavity, which is convenient for operation.
