Embodiment 1

[0026] Such as figure 1 with figure 2 As shown, an injection mold rack inclined ejector mechanism is characterized in that it includes a fixed guide block 1, and also includes an inclined ejector rod 2 and a straight ejector rod 3 arranged in an intersecting state, and the inclined ejector rod 2 and the straight ejector rod 3 is provided with a matching pattern; the matching pattern adopts the tooth pattern 4 arranged perpendicular to the axis of the straight ejector rod 3 . The guide block 1 is provided with a sliding passage for matching the inclined ejector rod 2 and the straight ejector rod 3. The sliding passage includes a first passage 5 for matching the inclined ejector rod 2 and a second passage 6 for matching the straight ejector rod 3. The first passage 5 Intersecting and communicating with the second channel 6, the ends of the first channel 5 and the second channel 6 are respectively provided with transition arcs. from image 3 It can be seen that the cross-sect...

Embodiment 2

[0029] An injection mold rack inclined top mechanism, such as Figure 5 As shown, the difference between Embodiment 2 and Embodiment 1 lies in that the inclined ejector mechanism also includes a limit block 16 fixedly arranged relative to the guide block 1, the shape of the straight ejector rod 3 is cylindrical, and the inclined ejector rod 2 adopts a horizontal The cross-sectional shape is a rectangular strip structure. Adaptive design also needs to be carried out according to the shapes of the straight ejector rod 3 and the inclined ejector rod 2 in the guide block 1 . The matching pattern includes the thread on the upper section of the straight ejector rod 3 and the helical teeth 17 on the inclined ejector rod 2, the lower section of the straight ejector rod 3 is provided with a transmission thread 18, and the straight ejector rod 3 is provided with a connecting ring 19 that is convexly arranged, and the transmission thread 18 is arranged on the wall surface of connecting ...

Embodiment 3

[0032] An injection mold rack inclined top mechanism, such as Image 6 As shown, the difference between embodiment 3 and embodiment 2 is that there are two inclined ejector rods 2, and the upper and lower gaps 23 are set between the two inclined ejector rods 2, that is, there is a gap 23 between the two inclined ejector rods 2. The two inclined ejector rods 2 are arranged on the same side of the straight ejector rod 3, and the helical teeth 17 on the two inclined ejector rods 2 are arranged in parallel; The height of the helical teeth 17 of 2 is greater than the height of the helical teeth 17 of the slant ejector rod 2 on the upper side; the height difference of the helical teeth 17 on the two slant ejector rods 2 adopts 1 millimeter.

[0033] By arranging two inclined ejector rods 2 side by side in parallel, double locking can be formed, thereby improving the stability of cooperation between inclined ejector rods 2 and straight ejector rods 3; The cooperation between the eje...

Abstract

The invention discloses an injection mold rack angle ejector mechanism. The mechanism is characterized by comprising a fixedly arranged guide block, and further comprising an angle ejector rod and a straight ejector rod which are arranged in an intersecting state, wherein matching lines are arranged on the angle ejector rod and the straight ejector rod, a sliding channel matched with the angle ejector rod and the straight ejector rod is arranged in the guide block, an angle ejector head is arranged on the angle ejector rod, a compression spring is arranged in the angle ejector head, the angle ejector head is in sliding connection with the angle ejector rod, the two ends of the compression spring abut against the angle ejector head and the angle ejector rod respectively to move upwards, and matched latch structures are arranged in the angle ejector head and on the side face of the angle ejector rod. The mechanism has the beneficial effects that lifting control over the angle ejector rod is completed through the lifting of the straight ejector rod, the lifting control over the angle ejector head can be realized through the arrangement of the compression spring between the angle ejector head and the angle ejector rod, and when an angle ejector is ejected to a mold, the latch structures are matched to shake, so that the ejection efficiency of the angle ejector can be improved; and the straight ejector rod and the angle ejector rod are mutually limited, so that the ejection stability of the angle ejector can be improved, and the ejection efficiency is high.

Description

technical field [0001] The present application relates to the technical field of a mold tilting mechanism, in particular to a rack tilting mechanism for an injection mold. Background technique [0002] At present, due to the limitation of some products, when the mold is demolded, the demoulding distance and angle of the inclined ejector pin need to be very large; the angle of the traditional inclined ejector pin should not exceed 13° theoretically, and it is required to exceed 13° Increase the inclined roof auxiliary rod. In the case of the inclined ejector rod, the limit cannot exceed 20 degrees. The inclined ejector rod occupies more mold space, and the mold is easily damaged during mass production, the inclined ejector rod is broken, and the ejection is not smooth. Abnormal noise will seriously affect mass production or even fail mass production, and it will take a long time for maintenance, which will delay mass production of products. [0003] For example, in the Chin...
