Description

Technical Field

[0001] The utility model relates to the field of mold buckling machines, in particular to a buckling machine structure for controlling the sequence of mold opening and closing. Background Art

[0002] The plastic mold lock mechanism, also known as the plastic mold clamping mechanism, is a key component of the injection molding machine. It is responsible for keeping the mold closed during the injection molding process and ensuring that the plastic material can evenly fill the mold cavity under high pressure. With the widespread application of plastic products, plastic molds are an important tool for manufacturing plastic products, and their performance and precision directly affect the quality of the final product. The main guarantee of the plastic mold lock mechanism is to ensure that the two parts of the mold are tightly combined during the injection molding process to prevent the leakage of plastic materials. And during the injection of plastic materials, it withstands pressures of up to hundreds or even thousands of bars. At the same time, it must be able to open and close quickly, and it needs to move quickly and accurately when the product is demoulded and the mold is closed.

The terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; for ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] like Figure 1-2 As shown, a buckle machine structure for controlling the opening and closing sequence of the mold includes a buckle machine 1, which includes a buckle machine support rod 9 and a buckle machine base 10. The buckle machine support rod 9 is fixedly mounted on the flow channel plate 2 of the mold, and the buckle machine base 10 is fixedly mounted on the rear mold B plate 4 of the mold. The buckle machine 1 also includes a second spring block 7 and a first spring block 8. The second spring block 7 and the first spring block 8 are mounted on the front mold A plate 3 of the mold. A first mounting head 11 is provided on the top of the buckle machine support rod 9, and a first mounting groove 5 is correspondingly opened on the surface of the flow channel plate 2. The first mounting head 11 is stuck in the first mounting groove 5 and fixed with screws. A No. 2 mounting head 12 is provided at the bottom of the machine base 10, and a No. 2 mounting groove 6 is correspondingly provided on the surface of the rear mold B plate 4. The No. 2 mounting head 12 is inserted into the No. 2 mounting groove 6 and fixed with a pair of screws. The No. 2 spring block 7 and the No. 1 spring block 8 have the same structure, and an avoidance slope 17 is provided under their surfaces. The No. 2 spring block 7 and the No. 1 spring block 8 are respectively movably embedded in the surface of the front mold A plate 3 through a plug screw 18, and a spring 19 is connected between the back of the No. 2 spring block 7 and the No. 1 spring block 8 and the embedding groove, so that the No. 2 spring block 7 and the No. 1 spring block 8 can elastically expand and contract along the plug screw 18.

[0021] In this embodiment, a horizontal right-angled groove 14 is provided at the center of the surface of the trigger support rod 9 for clamping the second spring block 7. An integral inclined protrusion 13 is also provided at the bottom of the trigger support rod 9. The inclined protrusion 13 has inclined surfaces on the upper and lower parts for pushing open the first spring block 8 and the second spring block 7.

[0022] In this embodiment, a vertical limit groove 15 is provided on the trigger base 10, and the trigger support rod 9 moves up and down along the limit groove 15. A top inclined surface 20 is provided on the top of the trigger base 10 for pushing open the No. 1 spring block 8 and the No. 2 spring block 7. The surface of the trigger base 10 is also provided with a No. 2 right-angle groove 16 for clamping the No. 1 spring block 8.

[0023] like Figure 3 As shown, in the mold closing state, the second right-angle groove 16 on the buckle machine base 10 just catches the top of the No. 1 spring block 8 to form a limit fixation. When opening the mold, due to the limit effect here, the front mold A plate 3 and the rear mold B plate 4 cannot be opened first, so that the upper flow channel plate 2 and the front mold A plate 3 are opened first, and the buckle machine support rod 9 is installed on the flow channel plate 2, so the buckle machine support rod 9 moves upward with the flow channel plate 2 until the inclined protrusion 13 at the bottom of the buckle machine support rod 9 contacts the No. 1 spring block 8. At this time, the upper inclined surface of the inclined protrusion 13 is against the avoidance inclined surface 17 of the No. 1 spring block 8. As the buckle machine support rod 9 continues to move upward, the No. 1 spring block 8 is squeezed back into the embedding groove, so that the No. 1 spring block 8 is separated from the limit of the buckle machine base 10. At this time, the flow channel plate 2 and the front mold A plate 3 are also opened, and the action can continue to open the front mold A plate 3 and the rear mold B plate 4.

[0024] like Figure 4As shown, in the mold opening state, the buckle support rod 9, the buckle base 10, the second spring block 7, and the first spring block 8 are separated from each other. When the mold closing action starts, the runner plate 2 moves downward with the buckle support rod 9, and the inclined protrusion 13 at the bottom of the buckle support rod 9 contacts the second spring block 7. The lower inclined surface of the inclined protrusion 13 can push the second spring block 7 open and retract it into the embedded groove, and then the buckle support rod 9 continues to move downward until the first right-angle groove 14 clamps the top of the second spring block 7. Thus, the movement between the flow channel plate 2 and the front mold A plate 3 is suspended, so that the front mold A plate 3 moves down first to close the mold with the rear mold B plate 4. At the same time, the lower slope of the inclined surface protrusion 13 contacts the first spring block 8, and also pushes it open and retracts it into the embedding groove. When the inclined surface protrusion 13 is separated from the first spring block 8, the first spring block 8 is ejected by the spring 19 and just stuck in the second right-angle slot 16, and the locking seat 10 is used to lock the limit again, thereby completing the closing of the front mold A plate 3 and the rear mold B plate 4. At the same time, until the top inclined surface 20 of the top of the locking seat 10 contacts the avoidance inclined surface 17 of the second spring block 7, as the downward movement continues, the top inclined surface 20 will push the second spring block 7 open and retract it into the embedding groove, thereby releasing the limit between the locking support rod 9 and the second spring block 7, so that the flow channel plate 2 and the locking support rod 9 can continue to move down, thereby completing the closing of the flow channel plate 2 and the front mold A plate 3.

[0025] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
