Description

Technical Field

[0001] The invention relates to the technical field of injection molding equipment, in particular to a constant temperature base for rod injection molding. Background Art

[0002] Injection molding is a method for producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding compression molding and die casting. Injection molding machine is the main molding equipment that uses plastic molding molds to make plastic products of various shapes of thermoplastics or thermosetting materials. Injection molding is achieved through injection molding machines and molds. During the molding process, rods need to be extruded. When the device is extruding, periodic control of the equipment can greatly improve production efficiency and save production time costs. However, for some injection molded products made of special materials, due to the particularity of the material itself, a certain constant temperature state needs to be maintained during the actual processing process, so as to ensure the stability and qualified rate of the product. Therefore, a constant temperature base for rod injection molding is needed to solve the above problems. Summary of the invention

[0003] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a constant temperature base for rod injection molding, which is used to solve the problem of constant temperature treatment during the injection molding process in the prior art.

[0004] To achieve the above objectives and other related objectives, the present invention provides the following technical solutions:

[0005] A constant temperature base for rod injection molding, comprising a guide seat, a rod base assembled at the output end of the guide seat, wherein a plurality of groups of hollow rod columns are detachably connected in the rod base, a constant temperature column for installing the rod columns is arranged in the rod base, the radial dimension of the constant temperature column is larger than the radial dimension of the rod columns, and a constant temperature through hole is opened on the side wall of the constant temperature column, the constant temperature through hole is connected to a constant temperature gas source, and an injection molding base for supporting the rod base and the rod columns is arranged at the bottom of the rod base.

[0006] To implement the above technical solution, a guide seat is set to guide the injection molding raw materials to the injection molding working surface of the rod base. The hollow rod column can ensure the injection molding stability of the rod. The setting of the constant temperature column can ensure the constant temperature requirement of the injection molding environment during the rod column injection molding process. The constant temperature through hole can facilitate the external constant temperature gas source to adjust the environment of the constant temperature column to achieve a temperature control effect.

[0007] In one embodiment of the present invention, a limiting ring is provided on the rod column, between the side close to the guide seat and the rod base, the radial dimension of the limiting ring is larger than the radial dimension of the rod column, and the limiting ring extends horizontally to the upper end surface of the rod base.

[0008] To implement the above technical solution, the setting of the limit ring can provide a limit support for the use of the plate through column, and the limit ring extends horizontally to the upper end surface of the rod base, which can better ensure the connection stability between the limit ring and the rod base.

[0009] In one embodiment of the present invention, a sealing groove for installing a sealing strip is provided on the rod base and below the limiting ring.

[0010] To implement the above technical solution, the sealing stability between the limit ring and the rod base can be ensured by setting a sealing groove, and a sealing gasket can be placed in the sealing groove to ensure the sealing between the limit ring and the rod base, thereby ensuring the stability of injection molding.

[0011] In one embodiment of the present invention, two sets of sealing rings are symmetrically arranged between the two ends of the rod column and the inner diameter of the constant temperature column, and a constant temperature cavity is formed between the inner wall of the constant temperature column between the two sets of sealing rings and the outer wall of the rod column, and the constant temperature through hole connects the constant temperature cavity with the outside world.

[0012] To implement the above technical solution, a constant temperature chamber can be formed by setting two sets of sealing rings, and the sealing stability of the constant temperature chamber can be ensured, so as to better ensure a constant temperature environment and meet the requirements of injection molding.

[0014] To implement the above technical solution, the base sealing groove and the pedestal sealing groove cooperate with each other, so that a sealed space can be formed between the bottom of the rod column and the injection molding base, which is convenient for the subsequent installation of the sealing gasket, thereby ensuring the constant temperature effect in the constant temperature column and avoiding leakage of the constant temperature gas, which affects the stability of the injection molding process.

[0015] In one embodiment of the present invention, a discharge through hole is provided on the injection molding base, and the radial dimension of the discharge through hole is smaller than the radial dimension of the base sealing groove and larger than the radial dimension of the inner wall of the rod through column.

[0016] To implement the above technical solution, by setting the radial size of the discharge hole smaller than the radial size of the base sealing groove and larger than the radial size of the inner wall of the rod column, the support stability of the injection molding base on the rod column can be ensured without affecting the removal of the rod after molding.

[0017] As described above, the rod injection-molded constant temperature base of the present invention has the following beneficial effects:

[0018] 1. By setting the guide seat, the injection molding raw materials are guided to the injection molding working surface of the rod base. The hollow rod column can ensure the injection molding stability of the rod. The setting of the constant temperature column can ensure the constant temperature requirement of the injection molding environment during the rod column injection molding process. The constant temperature through hole can facilitate the external constant temperature gas source to adjust the environment of the constant temperature column to achieve the temperature control effect.

[0019] 2. By setting two sets of sealing rings, a constant temperature chamber can be formed, and the sealing stability of the constant temperature chamber can be ensured, so as to better ensure a constant temperature environment and meet the requirements of injection molding.

[0020] 3. Through the cooperation between the base sealing groove and the base sealing groove, a sealed space can be formed between the bottom of the rod column and the injection molding base, which is convenient for the subsequent installation of the sealing gasket, thereby ensuring the constant temperature effect in the constant temperature column and avoiding leakage of constant temperature gas, which affects the stability of the injection molding process.

[0030] By setting the guide seat 1, the injection molding raw material is guided to the injection molding working surface of the rod base 2. The hollow rod column 3 can ensure the injection molding stability of the rod.

The setting of the limiting ring 7 can provide limiting support for the use of the plate through column, and the limiting ring 7 extends in the horizontal direction to the upper end surface of the rod base 2, which can better ensure the connection stability between the limiting ring 7 and the rod base 2.

[0032] A sealing groove 8 for installing a sealing strip is provided on the rod base 2 and below the limiting ring 7.

[0033] Two groups of sealing rings 9 are symmetrically arranged between the two ends of the rod column 3 and the inner diameter of the constant temperature column 4. A constant temperature cavity is formed between the inner wall of the constant temperature column 4 and the outer wall of the rod column 3 between the two groups of sealing rings 9.
