Description

A mold waste discharge device

technical field

The utility model belongs to the technical field of mechanical processing, in particular to a mold waste discharge device.

Background technique

At present, large-scale covered stamping parts are basically produced in automated production lines, and in automated production, waste discharge is a key indicator. It is often encountered in the production site that the waste is not smooth or the waste is intermittently stuck, which will greatly increase the shutdown rate, seriously reduce the beat of the stamping production line, and reduce production efficiency. If the accumulation of waste is serious, it will even damage the mold tooling and cause production ACCIDENT. The existing technology usually adopts the method of waste on the cylinder top for the problem of local waste stuck, as shown in Figure 1 and Figure 2, the existing mold waste discharge device 8 includes a small waste slide 1, a cylinder 2, a cylinder fixing plate 3, a slide Block 4, guide rod 5, support plate 6, air circuit 7 and other main components, the waste material is lifted by the cylinder 2 during work, S is the cylinder jacking stroke, the waste material will fall towards the center of gravity during the jacking process, and Fall on the big waste slide plate 9 below and finally discharge waste material, as shown in Figure 2, whole device carries waste material and does vertical reciprocating motion along with cylinder 2 during work, once reciprocating, pushes out a piece of waste material. But in actual production, because the waste is three-dimensional and has a relatively complicated shape, when the waste is lifted by the cylinder 2, the center of gravity of the waste coincides with the center of the ejector device, and the waste follows the small waste slide 1 straight up and down without falling to the large waste slide. In the case of 9, the waste cannot be discharged and accumulates. This slipping state cannot be predicted during mold design.

Utility model content

The purpose of this utility model is to provide a mold waste discharge device aiming at the defects of the prior art.

The technical scheme adopted by the utility model is: comprising a cylinder and a small waste slide plate, the upper end of the cylinder is fixed with a cylinder fixing plate, the piston rod of the cylinder passes through the cylinder fixing plate and is connected with the slider, and the left and right of the cylinder fixing plate are symmetrically arranged Guide rod, the two ends of the slider are slidably connected to the guide rod, the slider is fixed with a support rod, the support rod is fixedly connected with one end of the bottom of the small waste slide, and the other end of the bottom of the small waste slide is hinged through a hinge structure on the mold.

In a further preferred structure, the hinge structure includes a rotating shaft welded to the mold, a sleeve sleeved on the rotating shaft, and the sleeve is welded to the bottom of the small scrap slide.

In a further preferred structure, the bottom end of the cylinder is connected to an air circuit.

The utility model can change the moving direction of the waste materials, so that the waste materials can be discharged smoothly without accumulation of waste materials.

detailed description

The utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the utility model, but they do not limit the utility model.

As shown in Fig. 3 and Fig. 4, the utility model comprises a cylinder 2 and a small waste slide plate 1, the bottom end of the cylinder 2 is connected to the air circuit 7, the upper end of the cylinder 2 is fixed with a cylinder fixing plate 3, and the piston rod of the cylinder 2 Through the cylinder fixed plate 3 and connected with the slider 4, the cylinder fixed plate 3 is symmetrically provided with guide rods 5, the two ends of the slider 4 are slidably connected to the guide rod 5, and the slider 4 is fixed with a support rod 10. The support rod 10 is fixedly connected to one end of the bottom of the small waste slide 1, and the other end of the bottom of the small waste slide 1 is hinged to the mold 13 through a hinge structure. The hinge structure includes a rotating shaft 12 welded on the mold 13, a sleeve 11 sleeved on the rotating shaft 12, and the sleeve 11 is welded on the bottom of the small scrap slide 1.

The support rod 10 of the utility model is changed from the original steel plate support plate 6 to a round steel bar support structure. The utility model adds a hinge structure, including a rotating shaft 12 and a sleeve 11, and the sleeve 11 and the support rod 10 are welded on the small waste slide plate 1. On, the rotating shaft 12 is fixed on the mold 13.

When the utility model is working, the cylinder is jacked up, and the stroke is S. The small waste slide 1 and the support rod 10 move together with the cylinder. At the same time, the small waste slide 1 will rotate around the hinge structure at a certain angle α. The vertical reciprocating motion of 2 is converted into the rotary motion of the small waste slide 1, and the rotation angle α increases the sliding angle of the waste slide, which is more conducive to the falling of waste. α can be controlled by the cylinder stroke S and can be adjusted according to the actual situation; Simultaneously in the motion process, the small waste slide plate 1 has a pushing effect on the waste, and pushes the waste to fall. The size of the driving force is controlled by the speed of the air in and out of the cylinder 2, and can also be adjusted according to the actual situation. Through the rotation and thrust of the small waste slide 1, the waste is forcibly slid down and falls on the large waste slide 9 below to finally discharge the waste, thereby solving the problem of stuck waste.

The content not described in detail in this specification belongs to the prior art known to those skilled in the art.
