Description
Technical Field
The invention relates to a mold, in particular to an adjustable push rod ejection system of the mold.
Background
According to the traditional die-casting die push rod ejection system, push rods of the traditional die-casting die push rod ejection system are fixed on a push rod fixing plate, and all the push rods synchronously move along with the push rod fixing plate. The ejection distances of all push rods on the movable mold or the fixed mold are the same, and the ejection distances and the ejection sequence can not be adjusted. The disadvantages of the push rod ejection system and the ejection method are that: for thin-wall part die-casting products, the structural strength is weak due to the fact that the wall thickness is thin, and when the die-casting die is used for demolding, the wrapping force applied to each part of the thin-wall part die-casting products is different, the part subjected to the larger wrapping force is not easy to eject out by the push rod, and the push rod ejection system is not absolutely rigid. If all the push rods are ejected simultaneously and act on different parts of the product respectively, the part which is subjected to smaller wrapping force is ejected first, and the part which is subjected to larger wrapping force is ejected later, and all the parts of the final product are not ejected simultaneously, so that the product is easy to deform when being ejected; the shaping cost is increased in the later period, the time and the labor are wasted, and the production cost is increased. The individual products have larger deformation and can not meet the requirements of customers after shaping.

The adjustable push rod 3 in the embodiment adopts the split structural design, so that the processing and the assembly are convenient; particularly, the main push rod 33 can be obtained by adopting the existing push rod or simply correcting the existing push rod, so that the cost for processing the adjustable push rod 3 and the push rod ejection system is reduced.
As shown in fig. 3, the die holder 4 of this embodiment is provided with a limiting block 6 contacting with the push rod plate set 1. After the primary ejection is completed, the push rod plate group 1 moves in the opposite direction of the ejection direction until the push rod plate group 1 contacts the limiting block 6, so as to limit the moving stroke of the push rod plate group 1 and stop the push rod plate group 1 at the initial position, at this time, one end of the limiting rod 32 also contacts the die holder 4, and the first limiting protrusion 12 contacts the first push rod protrusion 31.
As shown in fig. 1 and fig. 2, an oil cylinder 7 is installed on the die holder 4 of the present embodiment, and a piston rod of the oil cylinder 7 is connected to the push rod plate group 1.

The adjustable push rod ejection system of the mold is applied to a die-casting mold in the embodiment, and the adjustable push rod ejection system can also be applied to other types of molds, such as an injection mold and the like in other embodiments. In this embodiment, the die holder 4 is specifically a movable die holder. The mold adjustable push rod ejection system is specifically mounted on the movable mold 100. The push rod plate group 1 is provided with a guide pillar which is arranged in a guide hole of the die holder 4 in a penetrating way. As shown in fig. 3 and 6, the adjustable tappet 3 and the non-adjustable tappet 5 are inserted into the race plate 81 and the insert 82 of the movable mold 100. In a mold closing state, one end of the limiting rod 32 is tightly contacted with the movable mold base, the limiting rod 32 is tightly contacted with the main push rod 33 to limit a reset distance, an upper main push rod bulge of the main push rod 33 is tightly contacted with the first limiting bulge 12 to fix the main push rod 33 at a set position, and the ejection end surface of the main push rod 33 is flush with the molding surface of the insert 82. In addition, the die casting mold in this embodiment further includes a fixed mold 200 and a side slider 83.
Because the initial distance is formed between the first push rod bulge 31 and the adjusting stud 2, when the push rod plate group 1 starts to push, the adjustable push rod 3 is not ejected, the first limit bulge 12 is not contacted with the first push rod bulge 31, and the adjustable push rod 3 moves reversely relative to the push rod plate group 1; the non-adjustable push rod 5 has ejection tendency and starts to apply ejection force to the corresponding part of the product 9; the adjustable push rod 3 starts to have ejection tendency after the adjustable stud 2 exceeds the initial distance, ejection force is applied to the corresponding part of the product 9, and the distance for applying the thrust to the product 9 by the adjustable push rod 3 is relatively shortened.
In the embodiment, during the die-casting production, according to the deformation detection result of the die-casting product, the deformation values of all parts of the product 9 are analyzed, the ejection distance of each push rod is adjusted on line according to the data, and the optimal ejection distance is selected for each push rod to correct the deformation problem of the product 9. And aiming at the part with the largest positive deformation of the detection result, namely the part with large wrapping force, using the non-adjustable push rod 5 as a reference. And aiming at the part with the detection result of negative deformation relative to the maximum positive deformation, namely small wrapping force, the adjustable push rod ejection system and the adjustable push rod 3 can be selected. In the demolding process, after the push rod plate group 1 starts to move towards the ejection direction, the push rod plate group 1 firstly pushes the non-adjustable push rod 5 to apply ejection force to the maximum positive deformation part of the product 9, and then different adjusting studs 2 on the push rod plate group 1 are driven to respectively apply ejection force to different parts of the product 9 after crossing different initial distances, so that the maximum positive deformation part of the product 9 is firstly subjected to ejection force, and the negative deformation part is later subjected to ejection force relative to the maximum positive deformation, so that the adjustable push rod 3 can lag behind the non-adjustable push rod 5 by a certain distance, and finally, the ejection positions of all push rods correspond to the deformation detection result of the product 9, thereby correcting the deformation problem of the product 9.
In addition, the system can independently adjust the ejection distance of each push rod relative to other push rods on line in the production process of the mold. The specific adjusting method for the ejection distance of the adjustable push rod 3 in the implementation comprises the following steps: the adjustable push rod 3 is completely ejected, the pipe wrench tool is used for rotating the adjusting part 34 at the head part of the adjustable push rod 3, and the adjusting part 34 is a non-matching part; the adjustable push rod 3 drives the adjusting stud 2 to rotate, and the adjusting stud 2 moves back and forth along the first through hole 11, so that the initial gap distance between the first push rod protrusion 31 and the second limiting protrusion 21 of the adjusting stud 2, namely the initial distance, can be adjusted, and the initial distance controls the ejection distance of the adjustable push rod 3. The first tappet protrusion 31 is also referred to as a stop flange shoulder of the adjustable tappet 3.
The adjustable push rod ejection system for the die in the embodiment can also be called as a push rod ejection system for the die-casting die, and the ejection distance of the die-casting die can be adjusted on line.
Compared with the traditional push rod ejection system, the adjustable push rod ejection system has the advantages that the structure is simple, the ejection distance of the adjustable push rod 3 can be flexibly adjusted on line, the die does not need to be disassembled, the problem of ejection deformation of thin-wall part die-casting products during die opening is solved, the later product shaping procedures are reduced, and the production cost is reduced.
