Abstract
The invention relates to the technical field of moulds, in particular to an elastic self-adaptive wear-free straight top block, which comprises a cavity plate and a core, wherein an elastic straight top block is inserted between the lower end of the cavity plate and the core, the upper end of the elastic straight top block is provided with an open slot, and a top block self-adaptive block is inserted into the open slot, so that the elastic straight top block is self-adaptively matched with a mould opening of the core when a mould is closed, and the quality of a product is ensured; the self-contraction separation die can form a gap by self-contraction separation of a die opening during die opening, and wear-free operation is realized during ejection, so that the service life of the injection mold can be greatly prolonged, the processing of the mold is simplified, the precision is improved, and the cost is reduced.
Description
Technical Field
The invention relates to the technical field of dies, in particular to an elastic self-adaptive abrasion-free straight ejector block.
Background
The ejection device of the injection mold and the mold core 'die orifice' matched with the ejection device need to bear repeated motion matching and surface friction, so that burrs of a product are easily caused by abrasion in the operation process, and the ejection device is a short plate of the service life of the mold all the time.
Disclosure of Invention
In order to solve the defects and problems of short service life of an injection mold in the prior art, the elastic self-adaptive wear-free straight ejecting block is provided.
The technical scheme adopted by the invention for solving the technical problem is as follows: the elastic self-adaptive wear-free straight ejector block comprises a cavity plate and a mold core, wherein an elastic straight ejector block is inserted between the lower end of the cavity plate and the mold core, the upper end of the elastic straight ejector block is provided with an open slot, and an ejector block self-adaptive adjusting block is inserted into the open slot.
The lower end of the elastic straight jacking block presses a jacking rod.
And a certain gap is kept between the elastic straight ejecting block and the side surface of the mold core.
And the clearance between the elastic straight ejecting block and the side surface of the mold core is less than 0.02 mm.
The invention has the beneficial effects that: compared with the prior art, the elastic self-adaptive wear-free straight ejector block disclosed by the invention realizes self-adaptive matching of the elastic straight ejector block and a 'die opening' of a core when a die is closed, so that the quality of a product is ensured; the self-contraction separation die can form a gap by self-contraction separation of a die opening during die opening, and wear-free operation is realized during ejection, so that the service life of the injection mold can be greatly prolonged, the processing of the mold is simplified, the precision is improved, and the cost is reduced.
Drawings
The invention is further described with reference to the accompanying drawings and the detailed description.
FIG. 1 is a schematic diagram of a matching structure between an elastic straight top block and a self-adaptive top block of the invention;
FIG. 2 is a schematic view of a fitting structure of an elastic adaptive wear-free straight top block in an open state of a mold according to the present invention;
fig. 3 is a schematic view of a matching structure of an elastic adaptive wear-free straight ejector block in a mold ejecting state according to the present invention.
The specific implementation mode is as follows:
as shown in fig. 1 to 3, the elastic self-adaptive wear-free straight top block of the present invention includes a cavity plate 1 and a core 2, an elastic straight top block 3 is inserted between the lower end of the cavity plate 1 and the core 2, a certain gap is maintained between the elastic straight top block 3 and the side surface of the core 2, the gap is smaller than 0.02mm, a top rod 4 is pressed by the lower end of the elastic straight top block 3, an open slot 31 is formed at the upper end of the elastic straight top block 3, and a top block self-adaptive adjusting block 5 is inserted into the open slot 31.
As shown in fig. 1 to 3, when the mold is closed, the ejector block adaptive adjusting block 5 is pressed into the open slot 31 of the elastic straight ejector block 3 under the action of the mold closing force, and due to the expansion effect of the slope, the open slot 31 is squeezed open to be tightly attached to the side surface of the mold core 2, so that a gap within 0.02mm is kept between the elastic straight ejector block 3 and the side surface of the mold core 2, and burrs are not generated during injection molding. After injection molding is completed, the mold is opened, the ejection block self-adaptive adjusting block 5 withdraws from the open slot 31 due to pressure cancellation, and meanwhile, the elastic straight ejection block 3 which is tightly attached by expansion rebounds so as to be separated from the side surface of the mold core 2, the mold performs ejection action, and the ejection block pushes up and ejects a product 0.
In conclusion, compared with the prior art, the elastic self-adaptive wear-free straight ejection block disclosed by the invention realizes self-adaptive matching of the elastic straight ejection block and a 'die orifice' of a core when a die is closed, so that the quality of a product is ensured; the self-contraction separation die can form a gap by self-contraction separation of a die opening during die opening, and wear-free operation is realized during ejection, so that the service life of the injection mold can be greatly prolonged, the processing of the mold is simplified, the precision is improved, and the cost is reduced.
The present invention has been described in accordance with embodiments thereof with the understanding that the present invention is not limited thereto but rather it is to be understood that variations and/or modifications may be made by those skilled in the art without departing from the scope of the invention as defined by the appended claims, and any such modifications, equivalents and the like as fall within the true spirit and scope of the invention.
