Description

Improvement of the balance structure of the flow path of the injection splitter plate

This creation provides a balanced structural improvement of the flow path of the injection mold splitter plate, especially suitable for the number of molding spaces (cavities) of six holes or multiples thereof.

According to the function of the flow channel system for injecting the shaped hot runner, the molten material sprayed by the nozzle of the molding machine is guided into the molding space, and the flow channel system comprises a sprue, a runner, a gate and a molding space. The track is the part that joins the nozzle of the molding machine, and the flow path is the main path of the molding material from the sprue to the molding space. The flow channel is configured to be equidistant and geometrically balanced from the sprue to each gate; that is, the material can be filled from the sprue at the same time to each molding space.

Please refer to Figure 1, the conventional type I flow channel configuration (1), the flow channel R is in a planar configuration. In order to achieve geometric balance, the flow channel R must be divided into many dendritic structures, so that although the geometric balance effect can be achieved, the processing is difficult. The flow path R has too many corners, resulting in excessive injection pressure loss.

Please refer to Figure 2, the conventional I-type flow channel configuration (2), the flow channel R is also in a planar configuration, the processing is simplified but the geometric balance effect is not good, need to be adjusted The R diameter of the rectifier channel is used to achieve the average filling effect of the cavity, resulting in different shear stresses of the cavity, and there are more restrictions on the injection processing conditions.

Please refer to Figure 3, the conventional I-type flow channel configuration (3), the flow channel R is also in a plane configuration, the flow channel R must be processed on both sides and combined with the high injection pressure and there is a doubt about leakage.

Therefore, how to overcome the ease of processing, the cornering effect and the high injection pressure, to achieve a geometric balance, and to make the innovation structure more economical and practical, the users are eagerly awaiting, and the relevant industry must strive to develop the goal and direction of breakthrough.

The creation of the balance structure of the mold splitter flow channel is improved, and the creator creates the lack of the conventional flow channel arrangement. The flow channel rod design of the column body allows the three-dimensional space of the flow channel to be stereoscopically arranged in the flow. In the track, and the length of the flow path from the injection path to each molding space is equal and geometric balance is achieved. The main purpose of this creation is to provide a balanced structural improvement of the flow path of the injection mold splitter plate in order to reduce the loss of injection pressure in the flow channel; another object of the present invention is to improve the complexity of the flow path processing and reduce the processing cost; Another object is to prevent the molten material from shearing heat in the flow path (SHEAR HEATING) to destroy the molecular structure. The technical feature of the problem solving is that the three-dimensional spatial three-dimensional flow channel is arranged and the flow path is self-injected to the geometrical balance configuration in which the lengths of the molding spaces are equal, and the molten material is turned over with the path by the three-dimensional flow channel. Making the center temperature of the molten material The boundary temperature is evenly mixed to achieve a filling balance of the straight multi-cavity.

With this innovative and unique design, this creation can achieve the following effects in comparison with the prior art: the balance structure of the flow path of the mold splitter plate is improved, the flow path is shortened by the flow path rod design, and the injection pressure is significantly reduced. Loss in the flow path; reducing the processing cost by improving the complexity of the flow path processing by the flow channel rod design; ensuring that the molten material is inverted with the path by the three-dimensional flow path, so that the center temperature of the molten material is uniformly mixed with the boundary temperature, Effectively achieve the filling balance of the linear multi-cavity hole; the flow path rod is easy to perform polishing processing and surface plating to improve the flow path roughness, effectively avoiding the molten material in the flow channel to damage the molecular structure due to shear heat generation; The flow path configuration can be performed without the limitation of the number of cavities being odd or even.
