Abstract
The mold core opposite-inserting structure of the tee pipe fitting mold comprises a mold core of the tee pipe fitting mold, wherein the mold core is composed of a straight-through mold core and a tee mold core, an opposite-inserting caulking groove is formed in the straight-through mold core, a U-shaped opposite-inserting portion is formed in the tee mold core, opposite-inserting faces are arranged on two sides of the U-shaped opposite-inserting portion and one end of the U-shaped opposite-inserting portion, the opposite-inserting faces are inserted into the opposite-inserting caulking groove, and the parting position of the other end of the U-shaped opposite-inserting portion is flush with the. The design characteristics of this scheme are that both do not have the blade butt joint, and the human body is difficult for the injury, reduce and damage the probability, and the polishing of the type department of being convenient for again is handled, reduces the joint line between tee bend core and the straight-through core, inserts in the tongue to inserting simultaneously, makes tee bend core and straight-through core butt joint firm, promotes life, improves production efficiency.
Description
Technical Field
The invention relates to a mold core opposite-inserting structure of a three-way pipe fitting mold, and belongs to the field of injection molds.
Background
The plastic products such as three-way plastic pipe fittings and the like are produced by adopting an injection mold, and in order to facilitate processing, the mold core of the three-way pipe fitting is mostly processed by sections and then is formed by butt joint. However, due to the limitation of a processing technology, the butt parting positions of the straight-through mold core and the three-way mold core of the conventional three-way pipe fitting are all in butt joint of cutting edges, the cutting edges are very sharp, parting lines can be reduced, but the cutting edges are easy to hurt operators, easy to crack and damage, short in service life and required to be normally maintained and replaced, and the production efficiency is influenced.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides the three-way pipe die core opposite-inserting structure which adopts an opposite-inserting structure, has smooth and excessive parting positions, has no cutting edge on a three-way die core, is not easy to damage and has long service life.
The technical scheme of the mold core opposite-inserting structure of the three-way pipe fitting mold is as follows: the mold core comprises a mold core of the three-way pipe fitting, and is characterized in that the straight-through mold core is provided with an opposite-inserting caulking groove, the three-way mold core is provided with a U-shaped opposite-inserting part, opposite-inserting surfaces are arranged on two sides and one end of the U-shaped opposite-inserting part, the opposite-inserting surfaces are inserted into the opposite-inserting caulking groove, and the parting position of the other end of the U-shaped opposite-inserting part is flush with the opposite-inserting caulking groove.
The scheme is mainly characterized in that the through core is provided with the opposite-inserting caulking grooves, the three-way core is provided with the U-shaped opposite-inserting parts, the two sides and one end of each of the two sides of the opposite-inserting parts are provided with opposite-inserting faces, the opposite-inserting faces are inserted into the opposite-inserting caulking grooves, the parting positions of the other ends of the opposite-inserting parts are flush with the opposite-inserting caulking grooves, and the design characteristics of the U-shaped opposite-inserting parts are that the three-way core and the through core are butted without cutting edges, the human body is not easily injured, the damage probability is reduced, the polishing treatment of the parting positions is facilitated, the parting lines between the three-way core and the through core are reduced, and meanwhile, the opposite-inserting caulking grooves are inserted into the opposite-inserting caulking grooves, so that the.
According to the mold core opposite-insertion structure of the tee pipe fitting mold, the straight-through mold core comprises the long core and the short core, the short core is provided with the groove, the long core is provided with the bump, the bump is in opposite-insertion fit with the groove, and the straight-through mold core is divided into the long core and the short core, so that the mold processing and assembling are facilitated. The opposite-inserting caulking grooves are arranged on the long core.

Detailed Description
The invention relates to a mold core opposite-inserting structure of a three-way pipe fitting mold, which comprises a mold core of the three-way pipe fitting mold as shown in figures 1-4, wherein the mold core is composed of a straight-through mold core 1 and a three-way mold core 2, an opposite-inserting caulking groove 3 is arranged on the straight-through mold core 1, a U-shaped opposite-inserting part 4 is arranged on the three-way mold core 2, opposite-inserting surfaces 5 are arranged on two sides and one end of the U-shaped opposite-inserting part, the opposite-inserting surfaces 5 are inserted into the opposite-inserting caulking groove 3, and the parting position 6 of the other end of the U-shaped opposite-inserting part 4 is flush with the opposite-. The scheme is mainly characterized in that the through mold core 1 is provided with the opposite-inserting caulking grooves 3, the three-way mold core 2 is provided with the U-shaped opposite-inserting portions 4, the two sides of the U-shaped opposite-inserting portions and one end of the U-shaped opposite-inserting portions are provided with the opposite-inserting faces 5, the opposite-inserting faces 5 are inserted into the opposite-inserting caulking grooves 3, the parting positions 6 of the other ends of the U-shaped opposite-inserting portions 4 are flush with the opposite-inserting caulking grooves 3, the U-shaped opposite-inserting portions 4 are designed and characterized in that no cutting edge is butted, a human body is not easily injured, the damage probability is reduced, polishing treatment of the parting positions is facilitated, parting lines between the three-way mold core and the through mold core are reduced, meanwhile, the inserting faces 5 are inserted into the opposite-inserting caulking grooves 3, the three-way mold. The straight-through core 1 comprises a long core 11 and a short core 12, a groove 13 is formed in the short core, a protruding block 14 is arranged on the long core, the protruding block 14 and the groove 13 are in butt-inserting fit, the straight-through core is divided into the long core and the short core, and mold processing and assembling are facilitated. The opposite inserting caulking grooves 3 are arranged on the long core 11.
