Abstract
The utility model discloses a mould for effectively removing burrs of an inner ring of a diaphragm, which comprises an upper mould, wherein the lower part of the upper mould is correspondingly connected with a middle mould, and the lower part of the middle mould is correspondingly connected with a lower mould; the upper part of the middle die is provided with an upper groove which is of an inward concave disc-shaped structure, the lower part of the upper die is correspondingly provided with a downwardly convex die core, the upper groove and the die core form a cavity, the lower part of the middle die is correspondingly provided with a lower groove, the upper part of the lower die is correspondingly provided with an upwardly convex lug, and the lower groove is correspondingly matched with the lug. The die core of the utility model does not need to be a cutting nozzle, so the service life of the die is greatly prolonged; the mould changes into three-layer mould, accomplishes directly cutting off between mold core and well mould, and it can be easy many to separate deckle edge in the mould die cavity, and then ensures that the inner circle deckle edge tears totally. A gap is reserved between the middle die and the lower die, and all burrs are connected together to be removed together when the burrs are removed.
Description
Technical Field
The utility model belongs to the technical field of the mould equipment and specifically relates to an effectively get rid of unedged mould of diaphragm inner circle.
Background
A plastic mold is a tool which is matched with a plastic molding machine in the plastic processing industry and gives a complete configuration and accurate dimension to a plastic product. Because of the variety and processing method of plastic, and the structure of plastic molding machines and plastic products are various, the variety and structure of plastic molds are also various. The mold is made up of several sets of component parts, the combination having a molding cavity therein. During injection molding, a mold is clamped on an injection molding machine, molten plastic is injected into a forming mold cavity and is cooled and shaped in the cavity, then an upper mold and a lower mold are separated, a product is ejected out of the mold cavity through an ejection system and leaves the mold, finally the mold is closed again for next injection molding, and the whole injection molding process is carried out in a circulating mode. The conventional die has a two-layer structure; the membrane structure requires good elasticity and high resilience, and the special rough edges of the materials are difficult to process. The cutting nozzle is made for improving the rough edge mold core, but the service life of the mold is short; due to material reasons, burrs or tears easily remain after processing after molding. If the cutting nozzle is too sharp, the inner ring burrs can remain in the cavity during demolding, and the production efficiency is very low. Therefore, it is necessary to design a mold for effectively removing burrs on the inner ring of the diaphragm.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects in the prior art, the die for effectively removing the burrs of the inner ring of the diaphragm is provided.
The utility model discloses a following scheme realizes:
a mould for effectively removing burrs of an inner ring of a diaphragm comprises an upper mould, wherein the lower part of the upper mould is correspondingly connected with a middle mould, and the lower part of the middle mould is correspondingly connected with a lower mould;
the upper part of the middle die is provided with an upper groove which is of an inward concave disc-shaped structure, the lower part of the upper die is correspondingly provided with a downwardly convex die core, the upper groove and the die core form a cavity, the lower part of the middle die is correspondingly provided with a lower groove, the upper part of the lower die is correspondingly provided with an upwardly convex lug, and the lower groove is correspondingly matched with the lug.
The upper groove is arranged in the middle of the upper portion of the middle die, the die core is correspondingly arranged in the middle of the lower portion of the upper die, and the upper groove is matched with the die core.
The convex block is correspondingly inserted into the lower groove, and a gap is correspondingly arranged at the joint of the convex block and the lower groove.
The die cavity is of a centrosymmetric structure, and solid cylindrical inner ring forming bulges are correspondingly arranged at the central symmetric axis of the die cavity.
The inner ring forming bulge and the mold core are integrally formed, the inner ring forming bulge is overlapped with a central symmetry axis of the cavity, and the inner ring forming bulge corresponds to the upper part of the middle mold.
The utility model has the advantages that:
the mold core of the mold for effectively removing the burrs of the inner ring of the diaphragm does not need to be a cutting nozzle, so the service life of the mold is greatly prolonged; the mould changes into three-layer mould, accomplishes directly to cut off between mold core and well mould, and because the hot tearing of the material of diaphragm can be poor relatively cold burden, so separate the deckle edge in the mould die cavity can be easy many, and then ensure that the inner circle deckle edge tears totally. A gap is reserved between the middle die and the lower die, and all burrs are connected together to be removed together when the burrs are removed.
