Abstract
Description
Technical Field
[0001] The utility model relates to the field of injection molding, in particular to a single-spring two-way reset type insert feeding mechanism. Background Art
[0002] When using injection molds to produce plastic products, sometimes there are some inserts inside the product, that is, before injection molding, the inserts are placed in the designated position of the cavity, and then the injection molding operation is performed, and finally the product with inserts is formed. Traditionally, the inserts will enter the material channel one by one under the action of the vibrating loading plate, and fall into the cavity through the material channel. Then, when the mold is closed, the slider set in the mold will close the bottom of the material channel, and the injection molding operation can be carried out.
[0003] However, some products need to be installed with two inserts. If the vibration loading tray, material channel and other mechanisms are simply set up as two sets, there will be cost issues on the one hand, and on the other hand, it will take up a large space and it will be difficult to make a reasonable layout.
[0004] Therefore, a method or device capable of solving the above problems is now needed. Summary of the invention
[0005] The utility model aims to solve the above-mentioned deficiencies in the prior art and proposes a single-spring bidirectional reset insert feeding mechanism which has a simple structure, ingenious design, reasonable layout, smooth movement and can save space.
[0006] The technical solution of the utility model is: a single-spring two-way reset insert feeding mechanism, characterized in that: the mechanism comprises a base 1, a feeding channel 2 is provided on the base 1, a material rack 3 is provided at the top opening of the feeding channel 2, a long hole 4 which is mutually interpenetrating and perpendicular to the feeding channel 2 is also provided in the base 1, a feeding shaft 5 is movably connected in the long hole 4, and the tail end of the feeding shaft 5 is fixedly connected to the output shaft 7 of the two-way cylinder 6,
[0007] The bottom of the base 1 is also provided with a first discharge channel 8 and a second discharge channel 9, and the first discharge channel 8 and the second discharge channel 9 are mutually connected with the feed channel 2 and are perpendicular to each other, and the first discharge channel 8 and the second discharge channel 9 are symmetrically distributed with the axis of the feed channel 2 as the axis.
[0008] A spring 10 is sleeved on the feed shaft 5, and the spring 10 is located in a limiting groove 11 opened in the base 1.
[0009] The end of the feeding shaft 5 is provided with a through trough 12. When the bidirectional cylinder 6 is in the middle position, the trough 2 is located at the bottom end of the feeding channel 2.
[0010] The feed shaft 5 is provided with a limiting segment 13, the outer diameter of the limiting segment 13 is H1, the outer diameter of the other parts of the feed shaft 5 is H2, H1<H2, the spring 10 is sleeved on the limiting segment 13, and the inner diameter of the spring 10 matches the outer diameter of the limiting segment 13, the outer diameter of the spring 10 is H3, H2<H3.
[0011] Compared with the prior art, the utility model has the following advantages:
[0012] This type of single-spring bidirectional reset insert feeding mechanism has a simple structure, ingenious design, and reasonable layout. It is designed to solve the problems of high cost and large space required for traditional multi-insert feeding, which requires multiple sets of feeding mechanisms. It uses a bidirectional cylinder to drive the feeding shaft to move. When the feeding shaft moves, it can transport the inserts dropped from the feed channel to the two discharge channels below, thereby realizing the feeding operation of two different discharge channels. This feeding structure only needs to be equipped with a set of material racks, vibrating loading trays and other mechanisms, which can effectively control costs and do not increase the space occupied by additional equipment. The feeding operation of multiple inserts can be realized. At the same time, its manufacturing process is simple and the manufacturing cost is low. Therefore, it can be said that it has many advantages and is particularly suitable for promotion and application in this field. Its market prospects are very broad. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 2 It is a structural schematic diagram of the spring in the embodiment of the utility model. DETAILED DESCRIPTION
[0015] The specific implementation of the present utility model will be described below in conjunction with the accompanying drawings. Figure 1 , Figure 2 As shown: a single spring two-way reset insert feeding mechanism, which includes a base 1 as a foundation, a feeding channel 2 is opened on the base 1, a material rack 3 is arranged at the top opening of the feeding channel 2, and a long hole 4 is also arranged in the base 1, which is mutually connected with the feeding channel 2 and perpendicular to each other, and a feeding shaft 5 is movably connected in the long hole 4, and the tail end of the feeding shaft 5 is fixedly connected to the output shaft 7 of the two-way cylinder 6,
[0016] The bottom of the base 1 is also provided with a first discharge channel 8 and a second discharge channel 9, and the first discharge channel 8 and the second discharge channel 9 are mutually connected with the feed channel 2 and are perpendicular to each other, and the first discharge channel 8 and the second discharge channel 9 are symmetrically distributed with the axis of the feed channel 2 as the axis.
[0017] A spring 10 is sleeved on the feed shaft 5, and the spring 10 is located in a limiting groove 11 opened in the base 1.
[0018] The end of the feeding shaft 5 is provided with a through trough 12. When the bidirectional cylinder 6 is in the middle position, the trough 2 is located at the bottom end of the feeding channel 2.
[0019] The feed shaft 5 is provided with a limiting segment 13, the outer diameter of the limiting segment 13 is H1, the outer diameter of the other parts of the feed shaft 5 is H2, H1<H2, the spring 10 is sleeved on the limiting segment 13, and the inner diameter of the spring 10 matches the outer diameter of the limiting segment 13, the outer diameter of the spring 10 is H3, H2<H3.
[0020] The working process of the single spring two-way reset insert feeding mechanism of the embodiment of the utility model is as follows: a plurality of inserts 14 are placed in a vibrating loading tray, and the vibrating loading tray is started. Under the action of the vibrating loading tray, a plurality of inserts 14 enter the material rack 3 in sequence, and the insert 14 at the bottom enters the feeding channel 2 from the outlet of the material rack 3, and falls into the material trough 12 opened on the feeding shaft 5.
[0021] Under the control of the pre-set program, the bidirectional cylinder 6 first drives the feed shaft 5 to move forward, and the insert 14 will move to the top of the first discharge channel 8 driven by the trough 12. Since the trough 12 is through, the insert 14 will escape from the trough 12 and fall into a specific position of the cavity through the first discharge channel 8; the feed shaft 5 returns to the initial position, another insert 14 enters the trough 12, the feed shaft 5 is recovered, and the insert 14 falls into the cavity through the second discharge channel 9, and finally the two inserts 14 are respectively fed into the cavity through the first discharge channel 8 and the second discharge channel 9;
[0022] After the mold is closed, the slider disposed in the mold is automatically reset to block the bottom ports of the first discharge channel 8 and the second discharge channel 9, and the injection molding process can be carried out.
[0023] Since a spring 10 is sleeved on the limiting section 13 on the feed shaft 5, the spring 10 can only move back and forth within the range of the limiting section 13 under the action of the limiting section 13. At the same time, since its outer diameter is larger than the outer diameter of the feed shaft 5, the end of the spring 10 will contact the inner wall of the limiting groove 11. In this way, no matter which direction the feed shaft 5 moves, the spring 10 will be compressed under the combined action of the step on the limiting section 13 and the inner wall of the limiting groove 11, and help the feed shaft 5 to automatically return to the initial position after the two-way cylinder 6 is deflated, waiting for material reception.
