Description
Technical Field
The utility model relates to a mold device field indicates strong magnetic rotor core rubber coating injection mold especially.
Background
The product is a part for cooling the inner rotor of the water pump motor, because the plastic is provided with running cooling water outside and the iron rotor in the middle can not contact water in the use process, and whether the performance of the side product is reduced or failed, high-temperature-resistant waterproof PPS + GF plastic needs to be wrapped outside, because the rotor combination insert has strong magnetism, when the rotor combination insert is placed in a positioning hole of an injection mold, if the rotor combination insert is not opened for a part of distance, the rotor combination insert is adsorbed by the insert (the mold parts are all made of magnet adsorbable steel), so that the rotor combination insert is difficult to be placed in the mold, and the traditional method for placing the rotor combination insert has the defects that ① mold cores need to be made of stainless steel, common stainless steel is not wear-resistant, the mold is short in service life, and needs to import expensive nonmagnetic mold steel, and ② mold cores are made of nonmagnetic steel, because the magnet can not be.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a appeal to rotor combination inserts is not enough to influence the strong magnetism rotor core rubber coating injection mold of rotor combination inserts installation.
The technical scheme of the utility model as follows:
the rubber coating injection mold for the strong magnetic rotor core comprises a movable mold core, a first sliding assembly and a second sliding assembly, wherein the first sliding assembly and the second sliding assembly are oppositely arranged on the top surface of the movable mold core; the movable mold core is provided with a positioning hole for inserting the iron core on the rotor assembly insert; an accommodating cavity is formed between the first sliding assembly and the second sliding assembly, and an annular gap and a filling space of encapsulated plastics are formed between the accommodating cavity and the iron core.
First slip subassembly and second slip subassembly all include the slider seat and set up the slider inserts on the slider seat working face, all are equipped with semi-circular recess on the work end of this slider inserts.
And a slide block positioning groove for limiting the slide block inserts of the first sliding assembly and the second sliding assembly is formed in the center of the top surface of the movable mold core.
The sliding block seat is formed by surrounding a vertical part and a transverse part into an L shape, and the transverse part and the vertical part are transited by an inclined plane; the top surface of the vertical part is provided with an inclined guide post hole.
The utility model has the advantages that: the utility model discloses well adoption injection mold slider structure commonly used, under the mould open mode, the slider also is open mode, can not pack into the mould into rotor combination inserts and produce the influence.

Wherein: FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the metal member structure of the present invention;
in the attached drawing, 1 is the movable mould core, 2 is the locating hole, 3 is for holding the chamber, 4 is the slider seat, 5 is the slider inserts, 6 is semi-circular recess, 7 is the slider constant head tank, 8 is vertical portion, 9 is horizontal portion, 10 is the rotor subassembly inserts.
Detailed Description
Referring to fig. 1 and 2, the injection mold for encapsulating the ferromagnetic rotor core comprises a movable mold core 1, a first sliding assembly and a second sliding assembly, wherein the first sliding assembly and the second sliding assembly are oppositely arranged on the top surface of the movable mold core; the movable mold core is provided with a positioning hole 2 for inserting the iron core shaft on the rotor assembly insert; an accommodating cavity 3 for encapsulating and injection molding is formed between the first sliding assembly and the second sliding assembly, and an annular gap and an encapsulating plastic filling space are formed between the accommodating cavity and the iron core. An accommodating cavity for encapsulating and injection molding is formed between the first sliding assembly and the second sliding assembly, and an annular gap and a position to be filled with encapsulating plastics are formed on the periphery of the accommodating cavity; because the sliding assembly keeps a certain distance with the rotor combined insert after being opened, the attractive force on the rotor combined insert is ensured not to be enough to influence the installation of the rotor combined insert.
The first sliding assembly and the second sliding assembly respectively comprise a sliding block seat and sliding block inserts 5 arranged on the working surface of the sliding block seat 4, semicircular grooves 6 are formed in the working ends of the sliding block inserts, and when the sliding block inserts on the two sides are in a tight closing state, annular gaps and positions needing to be filled by encapsulated plastics are formed between the sliding block inserts and the rotor assembly inserts; the slider seat stirs the slider to move backwards towards two positions when the die is opened through the inclined guide posts, and the slider seat is far away from the rotor assembly insert.
And a slide block positioning groove 7 for limiting slide block inserts of the first sliding assembly and the second sliding assembly is arranged in the center of the top surface of the movable mold core. Through setting up the slider constant head tank to first slip subassembly removes along the slider constant head tank with the second slip subassembly, plays the guide effect.
The slider seat is enclosed into L shape by perpendicular portion and horizontal portion, and the horizontal portion passes through by the inclined plane between the portion of erectting, perpendicular portion top surface is equipped with oblique guide post hole. The inclined surface is used for pressing the sliding block to resist the injection molding pressure by the fixed die in a die closing state; the top surface of the vertical part is provided with an oblique guide post hole, an oblique guide post rod is installed in the oblique guide post hole, and the oblique guide post rod can be fixed on the fixed die above, so that when the die is removed, the fixed die moves to drive the oblique guide post rod to move, the slider seat is indirectly opened towards two sides, and other slider structures can be used.
The above is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the techniques of the present invention are substantially any simple modification and equivalent changes to the above embodiments, all falling within the protection scope of the present invention.
