Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and in particular relates to a mold cavity structure and an electric heating bottle blowing mold. Background Art

[0002] Container bottles are generally blow-molded by injection-molded preforms through blow-molding molds. When blow-molding hot-fill bottles, the blow-molding mold is equipped with a heating structure. The traditional blow-molding mold has a flow channel surrounding the molding cavity, and then a fluid with a certain temperature is introduced into the flow channel to provide heat for the blow-molding mold. This heating structure requires a continuously flowing fluid to heat the blow-molding mold. There is a risk of leakage during the flow of the fluid, and it may even contaminate the container bottle. At the same time, the fluid heating method has a certain heat loss, resulting in low heating efficiency, and it takes a lot of energy to maintain the heating temperature of the blow-molding mold.

[0003] In order to solve the problems of low heating efficiency, high energy consumption and leakage risk of traditional bottle blowing molds, another heating structure has emerged. By configuring a heating tube in the bottle blowing mold for heating, it can eliminate the leakage, large heat loss and other problems existing in the fluid heating method. However, in the bottle blowing mold of this heating structure, the heating tube is powered by a connecting pipeline, and the pipeline connecting the heating tube is exposed to the bottle blowing mold, which not only affects the appearance of the bottle blowing mold, but also poses certain safety hazards.

The mold cavity connector 2 is installed in the mold cavity connector mounting position 11, and the wire passing recess 21 and the mold cavity 1 form a wire passing space; the mold cavity 1 has a mounting recess at one end near the bottle mouth, and the mold cavity 1 is provided with a plurality of wire passing holes extending longitudinally along the mold cavity 1, and the two ends of the wire passing holes are respectively connected to the wire passing space and the mounting recess. In this embodiment, by respectively providing the wire passing space and the mounting recess at both ends of the mold cavity 1, and providing the wire passing hole inside the mold cavity 1, the pipelines connected to the heating pipes in the mold cavity structure can be arranged through the wire passing holes and the wire passing space, and hidden in the mold cavity structure, thereby protecting the pipelines while making the mold cavity structure neater and more beautiful, avoiding the pipelines from being exposed in the mold cavity structure, and eliminating the safety hazards caused by the exposure of the pipelines.

[0026] In this embodiment, the mounting recess includes an upper clamp mounting position 12, a water pipe connection block mounting position 13 and a connector mounting position 14; a first wiring groove 141 is provided in the connector mounting position 14, and a second wiring groove 131 is provided in the water pipe connection block mounting position 13, and the second wiring groove 131 is connected to the first wiring groove 141; a plurality of wire passing holes include a first wire passing hole 15 and a second wire passing hole 16, the first wire passing hole 15 extends from the bottom of the first wire passing groove 141 along the longitudinal direction of the mold cavity 1 to connect to the wire space, and the second wire passing hole 16 extends from the bottom of the second wire passing groove 131 along the longitudinal direction of the mold cavity 1 to connect to the wire space.

[0027] like Figure 5 and Figure 6 As shown, based on the above-disclosed cavity structure, this embodiment also discloses an electric heating bottle blowing mold, including the above-disclosed cavity structure, upper clamp 3, water pipe joint block 4, connector 5, joint 6 and heating pipe, the upper clamp 3 is installed in the upper clamp installation position 12, the water pipe joint block 4 is installed in the water pipe joint block installation position 13, the connector 5 is installed in the connector installation position 14, and the joint 6 is connected to the connector 5; the positive electrode at one end of the heating pipe is electrically connected to the positive terminal of the joint 6, and the negative electrode at the other end of the heating pipe is electrically connected to the negative terminal of the joint 6. The electric heating mold of this embodiment heats the cavity 1 by arranging a heating pipe instead of a flowing hot fluid, thereby achieving the effect of energy saving and environmental protection.
