Description

Technical Field

[0001] The utility model belongs to the technical field of injection molds and relates to an injection mold guide column, in particular to an injection mold inclined guide column installation structure which is convenient for loading and unloading. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, and automated operation. Injection molding is suitable for mass production and molding processing fields such as products with complex shapes. The steps of injection molding are usually divided into the following steps: mold closing, injection, pressure holding, cooling, mold opening, and product removal.

[0003] like Figure 1 and Figure 2 The water chamber injection mold shown in the figure comprises an upper mold 1 and a lower mold assembly 3. A plurality of inclined guide pins 2 are installed on the upper mold 1. During the injection molding process, the inclined guide pins 2 are used to pull the slider in the lower mold assembly 3 apart, thereby achieving the demoulding effect. The conventional inclined guide pin processing is as follows Figure 2 As shown, holes are drilled on the upper die 1 and then the inclined guide pins 3 are tightly fitted in the upper die 1. This assembly method has the following disadvantages:

[0004] 1. The upper template is usually larger and thicker, and it is necessary to drill oblique holes on the upper template. The processing process is very slow and dangerous. Usually the water chamber mold is a large mold, nearly one meter long, 0.7-0.8 meters wide, or even larger. The stroke of ordinary machine tools is not enough, and it can only be processed on one side, so the processing speed is slow and dangerous, and the accuracy is not high.

[0005] 2. It is inevitable to repair the mold during the production process. If the inclined guide pin is broken, it is necessary to replace it with a new one. The only way is to remove the entire set of molds from the equipment and disassemble the upper mold to replace the inclined guide pin, which greatly affects production capacity.

[0006] Therefore, an injection mold inclined guide column installation structure that is easy to load and unload is designed. The structure can simplify the processing technology of the upper mold plate and facilitate the replacement of the inclined guide column. Utility Model Content

There is no need to remove the upper mold from the injection molding equipment and then take out the inclined guide column for replacement. The replacement is very convenient, which greatly improves the efficiency of accessory replacement.

[0011] The fixing seat is T-shaped, and the fixing groove is a T-shaped groove.

[0012] With the above structure, the fixed seat and the upper die are matched through a T-shaped structure, which is convenient for installation and positioning with high precision.

[0013] A guide post installation hole is obliquely opened in the fixing seat, the angle of the guide post installation hole is adapted according to the installation inclination angle of the oblique guide post, and the oblique guide post is installed in the guide post installation hole.

[0014] With the above structure, the inclined guide column is inserted into the guide column mounting hole for installation, and then installed in the upper mold through the fixing seat. The installation and replacement of the inclined guide column is very convenient; the fixing seat can be made into a standard part, the fixing seat is small in size, simple in structure, and easy to process. Compared with the existing processing method of opening a hole in the upper mold, it simplifies the processing technology, reduces the processing difficulty, and improves the assembly accuracy.

[0015] The fixing seat is connected to the upper die through bolts, a bolt mounting hole is provided on the fixing seat, and a bolt connection hole is provided in the fixing groove.

[0016] With the above structure, during installation, the fixing seat is placed into the fixing groove, the bolt is inserted into the bolt installation hole, and the bolt is screwed downward into the bolt connection hole to fix the fixing seat and the inclined guide column in the upper mold, which is very convenient to install and disassemble.

[0017] The number of the bolt mounting holes is two, which are symmetrically arranged on both sides of the guide column mounting hole.

[0018] Compared with the prior art, the injection mold inclined guide column installation structure that is easy to load and unload has the following advantages:

[0019] 1. Compared with the existing structure in which the inclined guide column is directly installed in the upper mold, the installation structure of the inclined guide column of the injection mold is improved on the basis of the existing mold. The inclined guide column is installed in the upper mold at an angle through the fixing seat. The inclined guide column is installed in the fixing seat, and the fixing seat is fixed in the upper mold by bolts. The installation and disassembly are very convenient. When the inclined guide column needs to be replaced, it only needs to remove the fixing seat to achieve the replacement. The operation is convenient and quick. There is no need to remove the upper mold from the injection molding equipment for replacement. It can be done directly on the machine. The replacement is very convenient, which greatly improves the efficiency of accessory replacement.

[0020] 2. In this structure, when processing the upper mold, it is only necessary to use CNC to process a fixing groove that is compatible with the fixing seat on the upper mold, without opening an inclined hole, thus avoiding safety hazards, greatly reducing the difficulty of processing, and ensuring processing accuracy; the fixing seat is small in size, simple in structure, and easy to process. The fixing seat can be made into a standard part, and it is also very convenient to install and disassemble, which simplifies the overall processing technology of the upper mold assembly and improves the processing efficiency of the mold.
