Example (b):

referring to fig. 1, the present embodiment shows an injection molding mold, which includes a rear mold assembly and a front mold assembly.

The rear die assembly comprises a rear die base plate 1, square iron 2, a rear die ejector plate 3, a return spring 5, a rear die ejector pin 4, a rear die plate 6, a rear die core 7 and a rear die insert 8.

The square iron 2 quantity has the polylith, and for example square iron 2 quantity is two in this embodiment, and two square iron 2 are the rectangular block, and the upper surface of back mould bottom plate 1 is provided with many locating pins, and two square iron 2 set up side by side, and square iron 2 pegs graft on the locating pin, and square iron 2 passes through the locating pin to be fixed at the upper surface of back mould bottom plate 1 to ensure the uniformity of square iron 2 and 1 course of motion of back mould bottom plate.

The two square irons 2 are enclosed to form a positioning groove, a plurality of positioning pins are also arranged in the positioning groove, and the positioning pins in the positioning groove penetrate through the rear die ejector plate 3, so that the rear die ejector plate 3 is fixed in the positioning groove. Wherein the rear mould thimble plate 3 is parallel to the rear mould bottom plate 1, and the rear mould thimble plate 3 and the square iron 2 are both positioned on the upper surface of the rear mould bottom plate 1. The thickness of the rear die ejector plate 3 is smaller than the height of the square iron 2, so that the entire rear die ejector plate 3 is located in the positioning groove.

The rear mold ejector pin 4 is installed on the rear mold ejector pin plate 3, wherein the rear mold ejector pin 4 is perpendicular to the rear mold ejector pin plate 3, and the lower end of the rear mold ejector pin 4 is fixed with the rear mold ejector pin plate 3. In addition, the upper surface of the rear mold ejector plate 3 is also fixed with a plurality of spring columns, the reset spring 5 is sleeved on the spring columns, the spring columns are parallel to the rear mold ejector pin 4, the lower end of the reset spring 5 is located on the upper surface of the rear mold ejector plate 3, and the spring columns can guide the deformation of the reset spring 5.

The spring columns and the rear mould ejector pins 4 penetrate through the rear mould plate 6, the rear mould plate 6 can move relative to the rear mould base plate 1 along the axial direction of the rear mould ejector pins 4, and the spring columns and the rear mould ejector pins 4 can guide the moving direction of the rear mould plate 6. Particularly, the diameter of the spring column is thicker than that of the rear mold ejector pin 4, so that the force borne by the rear mold ejector pin 4 can be effectively reduced, and the service life of the rear mold ejector pin 4 is prolonged. The rear die plate 6 extrudes the return spring 5 in the axial movement process along the rear die ejector pin 4, the lower end of the corresponding return spring 5 extrudes the upper surface of the rear die ejector pin plate 3, and the upper end of the return spring 5 extrudes the lower surface of the rear die plate 6.

The rear template 6 is always positioned above the square iron 2, and the rear template 6 projects onto the square iron 2 in the axial direction of the rear template thimble 4, so that the square iron 2 can limit the movement of the rear template 6.

Rear template 6 and back mould benevolence 7 all are the rectangular block approximately in this embodiment, and rear template 6 keeps away from the one side of back mould thimble board 3, and the upper surface of rear template 6 promptly has seted up the back mould benevolence groove with 7 shape assorted of back mould benevolence, and back mould benevolence groove is a rectangular channel approximately, and back mould benevolence 7 dismouting is in back mould benevolence groove department to make back mould benevolence 7 dismouting on rear template 6.

The rear mold insert 8 is approximately in a cup shape, and the rear mold insert 8 covers one surface of the rear mold core 7 far away from the rear mold ejector plate 3. And a material ejecting hole is formed in the cup bottom position of the rear mold insert 8, and the rear mold base plate 1 and the rear mold plate 6 generate relative motion in the axial direction of the rear mold ejector pin 4, so that the rear mold ejector pin 4 is far away from the end part of the rear mold ejector pin plate 3, namely the upper end of the rear mold ejector pin 4 enters and exits the material ejecting hole.

In this embodiment, the rear mold base plate 1 is fixed to the machine tool, and the rear mold plate 6 moves axially along the rear mold ejector pins 4, so as to control the upper ends of the rear mold ejector pins 4 to enter and exit the ejector holes, so that the steel product sleeved on the rear mold insert 8 is ejected from the rear mold insert 8, and separation between the rear mold insert 8 and the product is completed.

In order to match the rear mold inserts 8 with different heights, the lower ends of the rear mold ejector pins 4 are assembled and disassembled on the rear mold ejector pin plate 3 to replace the rear mold ejector pins 4 with different heights, so that ejection and separation operations are performed on products on different rear mold inserts 8.

The rear mold plate 6 moves axially along the rear mold ejector pin 4, so that the return spring 5 can be extruded in the process of separating the rear mold insert 8 from the product until the lower bottom surface of the rear mold plate 6 is extruded on the square iron 2, at the moment, the upper end of the rear mold ejector pin 4 is exposed out of the material ejecting hole, and the rear mold insert 8 is completely separated from the product. After the product is taken out, under the action of the return spring 5, the rear die plate 6 moves towards the direction far away from the square iron 2, and meanwhile, the rear die insert 8 pushes away the upper end of the rear die ejector pin 4, so that the upper end of the rear die ejector pin 4 is immersed into the rear die insert 8 again.

In addition, the rear mold insert 8 is also assembled and disassembled on the rear mold core 7, so that different products can be produced by the rear mold insert 8.

The front die assembly is movably arranged towards the rear die insert 8 and is matched with the rear die insert 8 to press a product.

The front mold assembly comprises a front mold panel 9, a front mold ejector plate 10, a front mold ejector 11, a front mold plate 12 and a front mold core 13.
