Abstract
The multifunctional mold core easy to withdraw from circular or square barrel or pipe consists of one mandrel with 4-6 dovetail lugs and several core clacks mounted on the mandrel. The mandrel has sides in an angle of 3-5 deg to its axis and heating tubes, and the core clacks have dovetails fitting the dovetail lugs in the mandrel and flow grooves. Between two adjacent core clacks, there is an interval of 8-10 mm. The core clack has inner side and outer side in the angle of 3-5 deg, and can slide along the dovetail lug.
Description
Technical field
The present invention relates to a kind of multifunctional mold core.
Background technology
At present, be the raw material manufacturing drum that is used for the splendid attire object, pipe or side's bucket, square tube with string, plastics and mineral waste residue on the market.Its manufacture method is with between raw material injection moulding die coat and the mold core, raw material is pushed form embryo bucket or embryonic tube, drying and moulding then.Its weak point is that mold core is difficult to withdraw from drum, pipe or side's bucket, square tube after moulding.
Summary of the invention
The objective of the invention is to solve in the very difficult problem that withdraws from from drum, pipe or side's bucket, square tube inner chamber of mold core, a kind of multifunctional mold core is provided.
The present invention is achieved in that it is provided with the mandrel 1 of 4-6 swallow-tail form projection 2 by lateral surface and the core lobe 4 that is installed on the mandrel 1 constitutes, the side of said mandrel 1 becomes 3-5 ° of angle with the axis of mandrel 1, mandrel 1 middle part is equipped with heating tube 3, be processed with the dovetail groove 6 that matches with swallow-tail form projection 2 on the said core lobe 4, on core lobe 4, have gutter channel 8, two orthogonal plane A1 are processed in the front side of core lobe 4, A2, core lobe 4 rear sides are processed into the vertical plane B1 that matches with the front side in the core lobe, B2, between two core lobes 4 that face mutually, the 8mm-10mm gap is arranged, corresponding gutter channel 8 positions have infiltration hole 5 on core lobe 4, core lobe 4 lateral surfaces are provided with infiltration net 7, the lateral surface of the medial surface of said core lobe 4 and core lobe 4 become 3-5 ° of angle, core lobe 4 can slide on mandrel 1 along swallow-tail form projection 2.
Advantage of the present invention is: because mandrel is processed into constant slope, the core lobe can slide on mandrel along the swallow-tail form projection, therefore mold core withdraws from from drum, pipe or side's bucket, square tube inner chamber smoothly, thereby improve the inner surface quality of finished product, prevent that mold core from withdrawing from drum the process, pipe or side's bucket, square tube inner surface scratch wound from drum, pipe or side's bucket, square tube inner chamber.
Description of drawings
Fig. 1 is a structural representation of the present invention; (corresponding embodiment 1)
Fig. 2 is a cutaway view of the present invention.
Among the figure: 1-mandrel, 2-swallow-tail form projection, 3-heating tube, 4-core lobe, the 5-hole of seeping water, 6-dovetail groove, the 7-net that seeps water, 8-gutter channel, A1-plane, A2-plane, B1-plane, B2-plane.
The specific embodiment
As shown in the figure, the present invention is provided with the mandrel 1 of 4 swallow-tail form projectioies 2 and the core lobe 4 that is installed on the mandrel 1 constitutes by lateral surface, the side of said mandrel 1 becomes 4 ° of angles with the axis of mandrel 1, mandrel 1 middle part is equipped with heating tube 3, be processed with the dovetail groove 6 that matches with swallow-tail form projection 2 on the said core lobe 4, on core lobe 4, have gutter channel 8, two orthogonal plane A1 are processed in the front side of core lobe 4, A2, core lobe 4 rear sides are processed into the vertical plane B1 that matches with the front side in the core lobe, B2, between two core lobes 4 that face mutually, the 8mm gap is arranged, corresponding gutter channel 8 positions have infiltration hole 5 on core lobe 4, core lobe 4 lateral surfaces are provided with infiltration net 7, the lateral surface of the medial surface of said core lobe 4 and core lobe 4 become 4 ° of angles, core lobe 4 can slide on mandrel 1 along swallow-tail form projection 2.
During use, form the raw material chamber when mould fuse is static and between the die coat, after raw material was filled slurry, die coat was extruded and reaches matched moulds, and raw material is compressed in around the mould fuse, and moisture flows to gutter channel 8 from infiltration hole 5, discharges the mould fuse.At this moment the heating tube 3 of die coat and mandrel 1 begins heat dryings, after the drying, and the die coat die sinking, mandrel 1 is pulled decline, and the dovetail tangs 2 on the mandrel 1 drives core lobe 4 and shrinks, and the mould fuse is deviate from the object that is extruded, object is taken out, both finished the effect of mould fuse and die coat.
