Description

Technical Field

[0001] The utility model relates to the technical field of processing molds, in particular to a plastic shell processing mold which is easy to demould. Background Art

[0002] When processing a plastic shell, an injection mold is generally used for injection molding. After the plastic shell is molded in the injection mold, the shell is easily stuck in the mold, which will affect the discharge speed. Therefore, in order to improve work efficiency, it is necessary to increase the demoulding speed of the injection mold. After searching, the Chinese patent publication number CN219360194U discloses a plastic shell processing mold that is easy to demould. The interior of the fixed groove is provided with a demoulding base mechanism, and the demoulding base mechanism is composed of a first base and a second base; the upper surfaces of the first base and the second base are both provided with a demoulding ejection mechanism. The utility model allows gas to enter the interior of the mounting rod from the inflation tube through the operation of an external air pump, so that the movable rod and the floating plate arranged at its bottom end are moved upward by the increase in air pressure. At the same time, through the setting of the electric telescopic rod, the distance between the demoulding ejector rod and the movable rod can be increased, thereby moving the plastic shell upward from the mold cavity and ejecting it.

[0003] Although the above technical solution can automatically eject the plastic shell, it needs to be driven by an external air pump to supply air to drive the ejection during use, which increases the cost of use. In addition, when adjusting the distance of the demoulding ejector rod, the corresponding electric push rod needs to be adjusted, which requires the use of electricity to drive, further increasing the cost of use.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

[0023] like Figures 1 to 5As shown, a plastic shell processing mold which is easy to demould comprises a base 1, the upper surface of the base 1 is fixedly connected with a U-shaped frame 2, the upper surface of the U-shaped frame 2 is penetrated and fixedly installed with a cylinder 3, the upper surface of the base 1 and the bottom end of the cylinder 3 are respectively fixedly connected with a lower die seat 4 and an upper die seat 5, the interior of the lower die seat 4 is embedded with a plastic shell processing die 6, the lower surface of the upper die seat 5 is fixedly installed with a plastic shell processing punch 7 which matches the plastic shell processing die 6, the lower surface of the lower die seat 4 is installed with an automatic reset ejection mechanism 8 which matches the plastic shell processing die 6, the outer surface of the upper die seat 5 is fixedly installed with an adjustable linkage mechanism 9 which matches the automatic reset ejection mechanism 8, the lower surface of the upper die seat 5 is fixedly connected with a plurality of positioning rods 10, and the upper surface of the lower die seat 4 is provided with a plurality of positioning holes 11 which match the positioning rods 10. When the plastic Vanke needs to be demolded after molding, the cylinder 3 drives the upper mold base 5 and the punch 7 to move upward, and at the same time drives the adjustable linkage mechanism 9 to move upward, thereby driving the automatic resetting ejection mechanism 8 to move upward, and then the molded plastic shell in the plastic shell processing die 6 can be ejected, which is convenient for demolding. No additional drive is required for demolding, which reduces the cost of use, thereby solving the problem that the existing mold needs to use an additional drive to demold during demolding, thereby increasing the cost of use.

[0024] Embodiment 2:

[0025] like Figure 2 and Figure 4 As shown, the automatic reset ejection mechanism 8 includes a moving plate 81 located below the lower die base 4, a plurality of ejection rods 82 are fixedly connected to the upper surface of the moving plate 81, the ejection rods 82 sequentially penetrate the lower die base 4 and the plastic shell processing die 6, the top of the ejection rod 82 is fixedly connected to an ejection plate 83, the inner bottom of the plastic shell processing die 6 is provided with a receiving groove 84 matched with the ejection plate 83, and a lifting plate 85 is fixedly connected to one side of the outer surface of the moving plate 81. A spring 86 is fixedly connected between the lower surface of the lower die base 4 and the upper surface of the moving plate 81. The upper surface of the movable plate 81 is slidably connected with a guide rod 87 fixedly connected to the lower surface of the lower mold base 4. The lifting plate 85 moves upward to drive the movable plate 81 to move upward, thereby driving the ejector rod 82 and the ejector plate 83 to move upward, so that the molded plastic shell can be ejected to facilitate demolding, and when the plastic shell processing punch 7 descends, the spring 86 will automatically drive the movable plate 81, the ejector rod 82 and the ejector plate 83 to reset.

[0026] Embodiment 3:

[0027] like Figure 2 and Figure 5As shown, the adjustable linkage mechanism 9 includes an L-shaped plate 91 fixedly connected to one side of the outer surface of the upper mold base 5, and an opening 92 is provided at the bottom end of the L-shaped plate 91.

The screw rod 95 passes through the top plate 93 and is threadedly connected to the top plate 93. A knob 96 is fixedly connected to the top of the screw rod 95. When the ejection distance needs to be adjusted, it is only necessary to rotate the knob 96. The rotation of the knob 96 drives the screw rod 95 to rotate, and the top plate 93 is driven up and down by the thread, so that when the cylinder 3 is running, the ejection rod 82 and the ejection plate 83 can be driven to move with different strokes, thereby solving the problem that the existing mold needs to drive the electric push rod when adjusting the ejection stroke, which further increases the use cost.

[0028] Working principle: when the plastic Vanke needs to be demolded after molding, the cylinder 3 drives the upper mold base 5 and the plastic shell processing punch 7 to move upward while driving the adjustable linkage mechanism 9 to move upward, thereby driving the automatic reset ejection mechanism 8 to move upward, and then the molded plastic shell in the plastic shell processing die 6 can be ejected, which is convenient for demolding. No additional drive is required for demolding, which reduces the cost of use, thereby solving the problem that the existing mold needs to use an additional drive to demold during demolding and increase the cost of use. When the ejection distance needs to be adjusted, only the knob 96 needs to be turned. The rotation of the knob 96 drives the screw 95 to rotate, and the ejector plate 93 is driven up and down by the thread, so that when the cylinder 3 is running, the ejector rod 82 and the ejector plate 83 can be driven to move with different strokes, thereby solving the problem that the existing mold needs to drive the electric push rod when adjusting the ejection stroke, which further increases the cost of use.
