Referring to fig. 1-4, in an embodiment of the present invention, a front-mold explosive type slide nested core-pulling mechanism includes:
a line 1, the line 1 being for forming a body portion of a product 5;
the core-pulling slide 2 is slidably arranged in the slide 1, a first insert 3 is fixed on the core-pulling slide 2, and the first insert 3 comprises a first substrate 31 and a plurality of insert pins 32 fixed on the first substrate 31; the insert pin 32 is used for forming a hole on the product 5;
In this embodiment, the slide 1 is used for molding a main body portion of a product 5, and the first insert 3 is used for molding a hole on the product 5; the second insert 4 is used for limiting and fixing the product 5 when the core-pulling slide 2 is separated from the product 5, so that the demolding process of the first insert 3 is facilitated, and the deformation of the product 5 is avoided.
If the structural modeling of the second insert 4 is directly processed at the slide 1, the processing difficulty and cost are increased, and in case that the core-pulling slide 2 collides with the slide 1, the economic loss is large.
In one embodiment, the front-mode explosive row nested core pulling mechanism further comprises a first return spring member disposed between the row 1 and the core pulling row 2.
The first return spring component is fixed on the slide 1, and the elastic force of the first return spring component acts on the core-pulling slide 2, so that the demolding and returning processes of the core-pulling slide 2 are facilitated.
In one embodiment, when the core back slide 2 is in a mold clamping state, a gap for accommodating deformation of the insert pin is formed between the first substrate 31 and the second substrate 41. The preferred choice of the gap thickness dimension is 1-2 cm.
In the sliding process of the core pulling slide 2 in the slide 1, the minimum distance between the first substrate 31 and the second substrate 41 is 1-2 cm. Thus, when the distance between the first substrate 31 and the second substrate 41 is minimized, a cavity is formed between the first substrate 31 and the second substrate 41. If the insert pin 32 fails to align with the through hole 43, the cavity provides a space for accommodating the deformed insert pin 32, thereby preventing the damage of the core-pulling slide 2 to the slide 1.
In one embodiment, the sliding in and out of the core slide 2 within the slide 1 is accomplished by a shovel 6.
A coordination hole matched with the shovel machine 6 is formed in the core-pulling slide 2, and when the shovel machine 6 extends into the coordination hole, the core-pulling slide 2 slides towards the second insert 4; when the shovel machine 6 leaves the matching hole, the core-pulling walking position 2 is far away from the second insert 4 to slide. The shovel 6 is a simple and efficient option to realize the movement of the core-pulling slide 2.
In one embodiment, the second insert 4 is provided with at least one positioning pin, and the first insert 3 is provided with a positioning hole aligned and matched with the positioning pin.
In this embodiment, the insert pins 32 on the first substrate 31 pass through the through holes 43 on the second substrate 41 to complete the molding process, and therefore, the alignment accuracy is important in the above process. The matching of the positioning pin and the positioning hole ensures that the alignment of the first insert 3 and the second insert 4 is accurately realized through the matching of the positioning pin and the positioning hole.
In one embodiment, the perforation portion 42 includes a plurality of perforations 43, and a side of the perforations 43 aligned with the insert pin 32 is chamfered.
In the traditional forming, the whole core-pulling slide 2 passes through the slide 1 to complete the forming process, and the alignment problem of the core-pulling slide 2 and the slide 1 does not exist in the process. In the present application, the insert pins 32 on the first substrate 31 pass through the through holes 43 on the second substrate 41 to complete the forming process, so the alignment accuracy is very important in the above process.
The chamfer is provided to facilitate the insertion pin 32 to pass through the through hole 43, thereby preventing the insertion pin 32 from being damaged due to alignment failure caused by slight position difference.
In one embodiment, the insert pins 32 are aluminum pins or copper pins.
The insert needle 32 is made of an aluminum needle or a copper needle which is soft, so that the product 5 can be processed without accidentally damaging the slide 1 or the second insert 4 by the soft insert needle 32.
In one embodiment, the second insert 4 is fixed to the slide 1 by screws.
Simple, convenient and efficient, and is convenient for disassembly, assembly, maintenance and maintenance.
In one embodiment, a positioning insert is arranged on the slide 1 and used for limiting and positioning the core-pulling slide 2 in the sliding process of the core-pulling slide 2.
The core-pulling slide 2 is accurate in start-stop position in the sliding process of the slide 1, and the operation process of the whole mold is facilitated.
The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the same way in the protection scope of the present invention.
