Description

Technical Field

[0001] The utility model relates to the technical field of mold structures, in particular to a mold structure of a signal adapter for industrial automation equipment. Background Art

[0002] In industrial production, molds are various dies and tools used to obtain the desired products by methods such as injection molding, blow molding, extrusion, die-casting or forging, smelting, and stamping. Molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the object's appearance by changing the physical state of the molded material. In the mold processing industry, a structure of multiple (10+19) hardware terminals with sealing glue is applied to small products. Since the terminals have crescents corresponding to multiple directions and the space is small, the traditional processing method of aligning each terminal and inserting it into the mold will increase the injection molding cycle several times. If an external clamp is used to cover the terminals and then introduce them into the mold at one time, the vibration deviation in the crescent direction will cause mold compression, seriously affecting the production and quality of the product, and making mass production difficult.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figures 1 to 9The utility model provides a technical solution: a mold structure of a signal adapter for industrial automation equipment, comprising: a connecting mold base 12; a No. 1 connecting mold 19 is fixedly connected to one side of the connecting mold base 12; a disengaged rear mold 6 is arranged inside the No. 1 connecting mold 19; a dome pin 7 is equidistantly slidably arranged inside the disengaged rear mold 6; an ejection assembly is placed inside the connecting mold base 12, and the dome pin 7 is connected to the ejection assembly; a No. 2 connecting mold 20 is placed on a side of the No. 1 connecting mold 19 away from the connecting mold base 12; a front mold core 3 is arranged on the inner side of the No. 2 connecting mold 20; a front mold insert group 1 is arranged on the inner side of the front mold core 3; a front mold insert pin 2 is symmetrically arranged on one side of the front mold insert group 1; a movable insert 4 is symmetrically arranged inside the disengaged rear mold 6, and a product body 10 is provided on one side of the movable insert 4.

[0033] It can be understood that the utility model is to split the three sets of movable inserts 4 into three pieces for processing before making three sets of movable inserts 4 after being separated from the rear mold 6, and then make pin connections and screws to fix them. During production, all terminals are first assembled on the movable inserts 4 according to the crescent direction of the terminals, and then placed in the rear mold 6 for injection molding. The movable inserts 4 are cycled for production operations to ensure that the injection molding cycle is reasonable and the production is smooth without affecting the product structure and quality, and the mold processing cycle is controlled within the specified time to meet customer requirements. Before closing the mold, the dome pin 7 is first reset to the bottom, and then the movable insert 4 with the terminal installed is placed in the corresponding position of the rear mold 6 according to the fixed direction, and then the A plate is closed. Together with the front mold core 3, the side slider 5 moves inward to reset, and then the panel is closed to reset the front mold insert group 1 and the front mold insert pin 2. After they reach the position, the injection molding machine will start injection molding again. After the mold injection is completed, the mold is opened, and the panel is pulled open to drive the front mold insert group 1 and the front mold insert pin 2 to separate from the A plate and the product body 10. The mold is continued to be opened and the front mold core 3 is pulled open to separate from the product. At the same time, the side slider 5 is driven to move outward to separate from the product buckle hole. The external ejector pushes the needle plate 15 to drive the dome pin 7 and the movable insert 4 to eject the product body 10 from the rear mold 6. After fixing the product body 10 with a fixture, the movable insert 4 is pulled out to extract the product body 10. In this way, the product can be produced normally.

[0034] See also Figure 1 and Figure 9 The ejection assembly includes a needle plate 15, which is slidably arranged inside the connecting mold base 12. One end of the dome needle 7 is fixedly connected to the needle plate 15. A plurality of limit slide rods 16 are equidistantly slidably arranged inside the needle plate 15. The limit slide rod 16 is fixedly connected to the connecting mold base 12. A limit rod 17 is symmetrically slidably arranged inside the needle plate 15, and a spring 18 is sleeved on the outer side of the limit rod 17.

[0035] It is understandable that the present invention uses an external ejector rod to push the needle plate 15 to drive the dome needle 7 and the movable insert 4 to eject the product body 10 from the rear mold 6, thereby facilitating the removal of the product body 10.

[0036] See also Figure 1 and Figure 9 , and also includes a side slider 5, which is symmetrically arranged inside the rear mold 6.

[0037] It can be understood that the function of the side slider 5 of the present invention is to demould and vent the outer holes.

[0038] See also Figure 1 and Figure 9 After the mold 6 is separated, a runner rubber inlet pipe 9 is fixedly connected to the inside.

[0039] It can be understood that the runner inlet hose 9 of the present invention is an important component connecting the injection molding machine and the mold runner, and is used to transport the molten plastic particles from the injection molding machine to the runner system of the mold.

[0040] See also Figure 1 and Figure 9 The inner and outer sides of the front mold core 3 are provided with a No. 1 water delivery hole 8, and the outer side of the rear mold 6 is provided with a No. 2 water delivery hole 11.

[0041] It can be understood that the present invention introduces cooling water or other cooling medium through the No. 1 water transport hole 8 and the No. 2 water transport hole 11, effectively taking away the heat generated by the mold during the injection molding process, reducing the temperature of the mold and improving the heat dissipation efficiency.

[0042] See also Figure 1 and Figure 9 A guide rod 13 is symmetrically fixed to one side of the No. 2 connecting mold 20, and a guide cylinder 14 that cooperates with the guide rod 13 is symmetrically fixed to the inside of the No. 1 connecting mold 19.

[0043] It can be understood that the guide rod 13 on one side of the No. 2 connecting mold 20 of the present invention and the guide cylinder 14 in the No. 1 connecting mold 19 are guided and limited, thereby improving the stability of the mold closing between the No. 2 connecting mold 20 and the No. 1 connecting mold 19.

[0044] In the description of the present invention, it should be understood that the terms "coaxial", "bottom", "one end", "top", "middle", "the other end", "upper", "one side", "top", "inside", "front", "center", "two ends", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0045] In addition, the terms "first", "second", "third" and "fourth" are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second", "third" and "fourth" may explicitly or implicitly include at least one such feature.
