Embodiment 1

[0048] See figure 1 , An inclined top mechanism of an injection mold, including inclined top rod 1, cylinder body 2, inclined top block 3, sliding seat 4 and water collector 5. The inclined top block 3 is arranged at the end of the inclined top rod 1, and the key 31 is matched to make the inclined top block 3 and the inclined top rod 1 fixed; the cylinder block 2 is sleeved outside the inclined top rod 1, and a piston 11 is provided on the outer wall of the inclined top rod 1. The piston 11 is housed in the cylinder block 2, in the cylinder The bottom of the body 2 is threadedly connected with a mounting block 21. After disassembly and installation, the entire cylinder body 2 is a hollow arrangement with a lower end opening 113. The outer wall of the top of the cylinder body 2 is provided with two air inlet holes 22. 6 will be provided with a ventilation channel communicating with the outside, and the air inlet hole 22 is in communication with the ventilation channel, but the nu...

Embodiment 2

[0061] See Figure 11 to Figure 13 The difference from the first embodiment lies in the design of the piston 11. In this embodiment, the piston 11 is set in a cup shape, also made of fluoroelastomer, with its opening 113 facing, and the piston 11 has a piston 11 seat. The seat is clamped on the inclined top rod 1.

[0062] The specific working principle is: when the inclined mandrel 1 is lifted and demolded, the piston 11 is deformed by the pressure of the air above, causing the opening 113 to shrink. At this time, a gap is formed between the piston 11 and the inner wall of the cylinder 2, and the air is driven from the gap. Enter under the piston 11 until the demolding process is completed; when the inclined mandrel 1 is pulled back into position, the piston 11 is compressed, and the inner wall of the opening 113 of the piston 11 is deformed by the pressure of the air, causing the piston 11 to flatten the piston. The edge of the opening 113 of 11 is close to the inner wall of t...

Abstract

The invention discloses an angle ejection mechanism of an injection mold. The angle ejection mechanism comprises an angle ejector rod and a cylinder which is arranged on the angle ejector rod in a sleeving mode and fixed in a moving mold plate, a piston is arranged on the angle ejector rod and contained in the cylinder and can be driven by the angle ejector rod to slide up and down in the axial direction of the cylinder, it is defined that at least one air inlet hole which is communicated with the interior of the cylinder is formed in the outer wall of the cylinder, at least one one-way-circulation air tap which enables air to only enter but not come out of the cylinder is arranged at the bottom of the cylinder, the movement range of the piston is between the air inlet holes and the air taps, when the angle ejector rod is driven by an ejector plate to be lifted to conduct demolding, the piston produces a certain damping effect, the rising speed of the angle ejector rod is decreased, and the situation that due to the fact that the ejecting speed of the angle ejector rod is too high, the demolding quality of a product is affected is avoided; in the withdrawing process, the angle ejector rod piston compresses the air, and large damping can be produced, so that the speed of the angle ejector rod in the process of returning to a containing groove is just decreased to zero, and the service life is prolonged.

Description

Technical field [0001] The invention relates to an injection mold, in particular to an inclined top mechanism of the injection mold. Background technique [0002] The inclined top mechanism is a component used for the injection mold to support the inclined top block for the inclined top core pulling and demolding. The inclined top mechanism generally includes an inclined top rod and a sliding seat. Generally, the inclined top mechanism is lifted and lowered by a thimble plate, just like the announcement number. The patent for CN 204773312U discloses a "injection mold inclined ejector rod double concentric guide sleeve mechanism", which includes a movable template, under which there is a thimble plate, the thimble plate is installed with an inclined sliding seat, and the inclined sliding seat is connected to the inclined top The inclined ejector rod crosses the movable template diagonally, and the head of the inclined ejector rod is connected to the inclined ejector block. When th...
