Description

Technical Field

[0001] The invention relates to the field of metal forming, in particular to an injection mold for a part. Background Art

[0002] Metal injection molding (MIM) is a new near-net-shape forming technology that obtains the final product through processes such as forming, degreasing, sintering and post-processing. The technical advantage of MIM is that when producing small parts with complex structures, the dimensional accuracy is high and no or only a small amount of subsequent machining is required. However, for some parts with non-through cross-slots or hole structures, when forming slots / holes in different directions, in order to avoid the intersection of the running directions of the insert pin and the striker, which may cause damage to the striker, only slots / holes in a single direction for forming can be opened on the mold, and slots / holes in other directions of the parts need to be formed through secondary processing. Secondary processing not only increases the number of steps and production costs, but also some special-shaped slots / holes are difficult to achieve conventional processing, resulting in the inability to produce some parts. Summary of the invention

[0014] A plurality of the front mold plate assemblies are installed in the front mold plate assembly, and a side of the front mold plate assembly away from the rear shaping mechanism is pressed against the stripping plate assembly;

[0015] A reset assembly is arranged on the side of the front mold plate assembly facing the stripper plate group, and the side of the reset assembly facing the stripper plate group can press against the side of the inserting pin away from the stripper plate group to push the inserting pin to pop up.

[0032] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0033] Please refer to Figure 1-Figure 7 , an injection mold for a part, comprising an inlay pin, a front shaping mechanism, a rear shaping mechanism and a plurality of magnetic suction mechanisms;

[0034] The front shaping mechanism and the rear shaping mechanism are arranged opposite to each other;

[0035] One end of the front shaping mechanism is slidably inserted into the rear shaping mechanism, and the other end is located at one side of the rear shaping mechanism;

[0036] The first piece of the magnetic attraction mechanism is installed on one side of the front shaping mechanism, and the second piece of the magnetic attraction mechanism is installed on one side of the rear shaping mechanism, so that the front shaping mechanism and the rear shaping mechanism can be mutually attracted when the front shaping mechanism and the rear shaping mechanism are molded;

[0037] The plurality of magnetic attraction mechanisms are symmetrically arranged and respectively located at the front and rear sides of the front shaping mechanism and the rear shaping mechanism;

[0038] The front shaping mechanism includes a stripping plate group, a front template group and a plurality of front molding plate assemblies;

[0039] The insert pin is installed on the side of the stripping plate assembly facing the rear shaping mechanism;

[0040] The stripping plate assembly is arranged on a side of the front template assembly facing away from the rear shaping mechanism;

[0041] The front mold plate assembly is embedded in a side of the front mold plate assembly facing the stripper plate assembly;

[0042] A plurality of the front mold plate assemblies are installed in the front mold plate assembly, and a side of the front mold plate assembly away from the rear shaping mechanism is pressed against the stripping plate assembly;

[0043] A reset assembly is arranged on the side of the front mold plate assembly facing the stripper plate group, and the side of the reset assembly facing the stripper plate group can press against the side of the inserting pin away from the stripper plate group to push the inserting pin to pop up.

[0044] The working principle of the present invention is:

[0045] The magnetic suction mechanism is used to first tightly adsorb the front template group and the rear mold shaping mechanism when the front and rear mold shaping mechanisms are closed, and then the stripper plate group and the front template are combined to make the insert pins be pressed on the product. Conversely, the stripper plate group and the front template group can be separated first, and then the front template group and the rear shaping mechanism can be separated.

[0046] After the mold is opened, the stripper plate assembly and the front mold plate assembly are separated, and the right end of the front mold pressure plate assembly moves to the right to enable the reset assembly to eject the pin.

[0047] From the above description, it can be seen that the beneficial effects of the present invention are: the present invention is provided with a magnetic attraction mechanism, which is used for attracting each other when the front and rear shaping mechanisms are molded, so that the front template group and the rear shaping mechanism are molded in sequence, and then the stripper plate group and the front template group are separated in sequence when the mold is opened, and the stripper plate group is separated from the front template group and then the front template group is separated from the rear shaping mechanism; a reset assembly and a front mold pressure plate assembly are provided, which are used to push the insert pin installed on the left side of the stripper plate group to pop out when the stripper plate assembly and the front template group are separated, and can avoid the problem of motion interference between the insert pin and the hole when the mold is closed, and realize the sequential separation and closing of the insert pin and the hole or groove, so that it can be molded in one time, without considering the problem of motion interference between the insert pin and the hole, and the part molding is performed in two times, which simplifies the processing process and improves the processing efficiency.

[0048] Furthermore, the first block and the second block are magnets of opposite polarities.

[0049] From the above description, it can be seen that the first block and the second block are opposite-polarity magnets, which can be tightly adsorbed when the mold is closed, and play the role of fastening the front and rear shaping mechanisms.

[0050] Further, the rear shaping mechanism includes a rear mold insert, a rear mold plate, a rear mold base and a plurality of rear mold slide blocks;

[0051] The side wall of the rear mold plate facing the front shaping mechanism is provided with a receiving groove matching the rear mold insert;

[0052] The rear mold insert is embedded in the accommodating groove;

[0053] The rear mold plate is mounted on the rear mold base;

[0054] The two sides of the rear template are respectively provided with sliding grooves;

[0055] A plurality of rear mold slide blocks are installed in the slide groove and are arranged from the rear mold plate toward the front shaping mechanism to generate relative sliding between the front shaping mechanisms.

[0056] As can be seen from the above description, a rear mold slider is provided for positioning between the front and rear mold shaping mechanisms, so as to facilitate more accurate mold closing of the front and rear mold shaping mechanisms.

[0057] Furthermore, it also includes two diagonally arranged snap-fit ​​mechanisms, and the plurality of snap-fit ​​mechanisms are respectively located at the front and rear sides of the rear shaping mechanism;

[0058] One end of the buckling mechanism is connected to the front shaping mechanism, and the other end is connected to the rear shaping mechanism in a relatively slidable manner.

[0059] From the above description, it can be seen that the locking mechanism is provided to keep the front and rear mold shaping mechanisms in relative movement and to prevent the front and rear mold shaping mechanisms from completely separating during the mold opening process.

[0060] Further, the front mold assembly includes a front mold plate, a front mold first nozzle plate and a front mold insert;

[0061] The first nozzle plate of the front mold is slidably mounted on a side of the front mold insert away from the rear shaping mechanism and connected to the front mold pressure plate assembly;

[0062] The front mold insert is embedded in the side wall of the front mold plate facing the rear shaping mechanism;

[0063] A guide rod is installed on the side wall of the stripping plate group facing the rear shaping mechanism;

[0064] The guide rod passes through the front template and is inserted into the rear shaping mechanism, so that the stripping plate group and the front template can be stably separated from the rear shaping mechanism.

[0065] Further, it also includes a plurality of buckle base components;

[0066] A plurality of buckle base components are respectively installed on the upper and lower sides of the rear shaping mechanism and the front shaping mechanism.

[0067] Furthermore, the buckle base assembly includes a buckle base and a buckle block matching the buckle base;

[0068] The buckle base and the buckle block are respectively mounted on the rear shaping mechanism and the front shaping mechanism and are located on the same side, so that the buckle block can be buckled on the buckle base to achieve positioning when the front shaping mechanism and the rear shaping mechanism are molded together.

[0069] From the above description, it can be seen that when the front and rear mold shaping mechanisms are closed, it is first ensured that the front and rear mold shaping mechanisms are accurately positioned and can be closed, and then the front and rear mold shaping mechanisms continue to close the mold, which can improve the closing efficiency and facilitate positioning before closing the mold.

[0070] Further, the front mold plate assembly includes a front mold second gate plate and a front mold core;

[0071] The second nozzle plate of the front mold and the front mold core are relatively movably connected through a plurality of rubber columns, and the ends of the rubber columns are clamped in the reset assembly;

[0072] One end of the reset component is connected to the front template group, and the other end is connected to the glue column.

[0073] Furthermore, the reset assembly includes a pressure plate, a support plate, two springs and two guide pillars;

[0074] The upper and lower sides of the front mold core are respectively provided with reset grooves opening toward the stripping plate group;

[0075] The pressing plate and the supporting plate are sequentially installed in the same resetting groove;

[0076] One end of the guide column passes through the pressing plate and the supporting plate in sequence and is pressed between the pressing plate and the supporting plate;

[0077] The spring is sleeved on the outside of the guide column and is located on the side of the support plate away from the pressure plate, and one end of the spring presses against the front template group, and the other end presses against the side of the support plate facing the rear shaping mechanism;

[0078] One end of the glue column is clamped between the two guide columns, and the other end is connected to the second sprue plate of the front mold to drive the guide column to move.

[0079] From the above description, it can be seen that a glue column is provided to enable the second sprue plate of the front mold to drive the guide column, spring, pressure plate and support plate to move to the right through the glue column, so that when the stripping plate is separated from the front template, the pressure plate will push out the inlay pin, so that the front template and the stripping plate can be quickly separated.
