Figure 1 As shown, the outer wall of the plastic product 100 has multiple small grooves 101 and small holes 102. When opening the mold, the material head clamp cannot be removed using the traditional core-pulling structure. Utility Model Content

[0003] The purpose of this invention is to provide a front mold pusher plate for convenient material head clamping and sequential mold opening.

[0004] To achieve the above objectives, the technical solution of this utility model is:

[0005] This utility model is a front mold push plate sequential opening mold, including a panel, stripper plate, fixed template, moving template, shovel base plate, buckle, multiple shovel bases, multiple sliders, multiple cores, moving mold inserts, and shovel base springs;

[0006] The panel, stripper plate, and fixed template are sequentially connected together. The fixed template and the moving template are connected together. The moving mold insert is fixedly installed inside the moving template. The shovel base plate is movably installed inside the stripper plate. The shovel base spring is set between the shovel base plate and the stripper plate. The upper end of the buckle is fixed on the panel. The lower end of the buckle is installed on the shovel base plate. The upper ends of multiple shovel bases are all fixed on the shovel base plate. The lower part of the shovel base is movably inserted into the guide groove of the slider. The outer end of the core is fixed to the inner end of the slider. The inner end of the core extends into the cavity. The slider slides on the moving mold insert or the fixed template.

[0007] The shovel base includes two first shovel bases and four second shovel bases, and the slider includes two first sliders and four second sliders; the first shovel bases are movably inserted into the guide grooves of the first sliders, and the first sliders are slidably connected to the moving mold insert; the second shovel bases are movably inserted into the guide grooves of the second sliders, and the second sliders are slidably connected to the fixed mold plate.

[0008] The buckling mechanism includes a buckling rod, a buckling plate, a buckling spring, and an inclined pressure block. The upper end of the buckling rod is fixed to the panel, and the lower end of the buckling rod has a hook that hooks onto the bottom surface of the buckling plate. The buckling plate slides in the plate groove on the side of the shovel base plate. The buckling spring is located between the inner end of the buckling plate and the inner wall of the plate groove. The inclined pressure block is installed on the stripper plate, and the inner side of the inclined pressure block has an inclined pressure surface that can abut against the inclined surface on the outer side of the buckling plate.

[0009] This utility model also includes a square iron, a bottom plate, a top plate, a top rod, and a return spring; the moving template is fixed to the bottom plate by the square iron, forming an ejection space between the moving template and the bottom plate, the top plate is installed in the ejection space, the lower end of the top rod is fixed to the top plate, the upper end of the top rod passes through the moving template and extends into the cavity, and the return spring is installed between the moving template and the top plate.

[0010] After adopting the above solution, since this utility model includes a panel, a stripper plate, a fixed template, a moving template, a shovel base plate, a clamping mechanism, multiple shovel bases, multiple sliders, multiple cores, and a moving mold insert; when the mold is opened, the panel separates from the stripper plate, the stripper plate separates from the fixed template, the stripper plate removes the material head from the sprue, making it convenient to clamp the material head. At this time, the clamping mechanism pulls the shovel base plate so that the shovel base plate will not move downward. After the mold is opened to a certain distance, the clamping mechanism disengages from the shovel base plate. At this time, the clamping mechanism pulls the shovel base plate and drives multiple shovel bases to move downward. The shovel bases drive the sliders to move outward, thereby driving the core to complete the core pulling.

The moving template 4 is fixed to the base plate 5 by square iron. An ejection space is formed between the moving template 4 and the base plate 5. The top plate 12 is installed in the ejection space. The lower end of the ejector rod 13 is fixed to the top plate 12. The upper end of the ejector rod 13 passes through the moving template 4 and extends into the cavity. The reset spring 14 is installed between the moving template 4 and the top plate 12.

[0019] The moving mold insert 6 is fixedly installed inside the moving template 4, the shovel base plate 7 is movably installed inside the stripper plate 2, the shovel base spring 15 is disposed between the shovel base plate 7 and the stripper plate 2, the upper end of the buckle 8 is fixed on the panel 1, the lower end of the buckle 8 is installed on the shovel base plate 7, the upper ends of multiple shovel bases 11 are all fixed on the shovel base plate 7, the lower part of the shovel base 11 is movably inserted into the guide groove of the slider 9, the outer end of the core 10 is fixed to the inner end of the slider 9, the inner end of the core 10 extends into the cavity, and the slider 9 slides on the moving mold insert 6 or the fixed template 3.

[0020] The shovel base 11 includes two first shovel bases 111 and four second shovel bases 112, and the slider 9 includes two first sliders 91 and four second sliders 92; the first shovel bases 111 are movably inserted into the guide grooves 911 of the first sliders 91, and the first sliders 91 are slidably connected to the moving mold insert 6; the second shovel bases 112 are movably inserted into the guide grooves 921 of the second sliders 92, and the second sliders 92 are slidably connected to the fixed mold plate 3.

[0022] The working principle of this utility model:

[0023] When the mold is opened, the panel 1 separates from the stripper plate 2, and the stripper plate 2 separates from the fixed mold plate 3. The stripper plate 2 removes the sprue head from the sprue gate, making it easier to clamp the sprue head. At this time, the clamping mechanism 8 pulls the shovel base plate 7 so that the shovel base plate 7 will not move downward. After the mold is opened to a certain distance, the clamping mechanism 8 disengages from the shovel base plate 7. At this time, the clamping mechanism 8 pulls the shovel base plate 7 and drives multiple shovel bases 11 to move downward. The shovel bases 11 drive the slider 9 to move outward, thereby driving the core 10 to complete the core pulling.

[0024] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the patent application and the contents of the specification of the present utility model should still fall within the scope of the patent of the present utility model.
