Problems solved by technology

In the existing technical scheme, the joint of the water channel on the mold core and the water channel on the formwork is often connected with a sealing ring, but after long-term practice, it is found that the sealing ring at the joint is easy to cause water leakage, because the sealing ring In the case of pressure and temperature changes, deformation will occur, which will lead to the problem of poor sealing effect of the sealing ring, and a large amount of water leakage will affect the molding of the product

Embodiment Construction

[0013] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0014] Please refer to the attached Figures 1 to 3 , the embodiment of the present invention includes:

[0015] A waterway docking structure on an injection mold for chopsticks, comprising a fixed mold core 1, a male joint 2 and a female joint 3. The fixed mold core 1 comprises a molding part and an installation part, and the installation part is a stepped revolving body. The shaft core of the fixed mold core 1 is provided with a waterway 4, and the waterway 4 is opened from the rear end face of the fixed mold core 1. The axial direction of the mold core 1 extends toward the front end of the fixed mold core. The design of the waterway 4 is to ...

Abstract

The invention discloses a water route docking structure on a chopstick injection mold, and relates to the field of daily life tableware preparation. The water route docking structure comprises a fixed mold core, a male joint and a female joint. A water route is formed in the axis of the fixed mold core. The male joint and the female joint are docked in the axial direction and then are installed at an inlet of the water route. Both the male joint and the female joint are internally provided with axial runners. The docking surface of the male joint and the female joint is of a convex cone matching structure. The water route docking structure solves the problem that water leaking is likely to happen since a sealing ring is adopted in the original structure; the convex cone matching surface is used for preventing water leakage, so that the docking structure is improved ingeniously; even though water seepage occurs, it still can be controlled within a disposable range, and therefore safety of the overall structure is improved.

Description

technical field [0001] The invention relates to the field of tableware preparation for daily life, in particular to a waterway butt joint structure on an injection mold of chopsticks. Background technique [0002] In the disposable chopsticks injection mold, the cooling system is the core part, which has an important impact on the life of the mold, the production efficiency and quality of injection molded products. The influence of the waterway on the quality of the molded product is mainly manifested in the molding of the product. The waterway is used to control the mold temperature, and the change of the mold temperature has an impact on the shrinkage deformation, dimensional stability, mechanical strength, stress cracking and surface quality of the product. influences. In the existing technical scheme, the joint of the water channel on the mold core and the water channel on the formwork is usually connected with a sealing ring, but after long-term practice, it is found t...
