When the pipe is clamped and pressed, the pipe is generally opened firstly, put into the pipe and pressed, and the middle space is reduced to squeeze and deform the pipe, so that the clamping and pressing connection of the pipe is realized.

Although the mold core of the existing clamping and pressing device is provided with a plurality of split parts, the mold core can accurately enclose a circle in the process of pressing, so a guide mechanism can be arranged between the split parts, generally, a guide rod is arranged on one split part, and a guide groove matched with the guide rod is arranged at the corresponding position of the other split part.

Disclosure of Invention

An object of the utility model is to provide a solve above-mentioned problem, practiced thrift processing man-hour and cost, improved the mould core for the crimping of the socket joint pressfitting pipe fitting of the life of mould core.

In order to achieve the above purpose, the utility model adopts the technical scheme that: a die core for crimping a socket pressing pipe fitting comprises an upper half body and a lower half body, wherein the upper half body consists of an upper die clack and two split parts, and the lower half body consists of a lower die clack and two split parts;

in the upper half body, a slot is respectively arranged on the upper mould section and the contact surface of the upper mould section corresponding to the two split sections, an inserting block matched with the slot is arranged at the position corresponding to the slot on the top of the split section, the upper half body is an integral body, the upper mould section with the slot and the split section with the inserting block are formed by integral cutting, blind holes are arranged on the opposite surfaces of the upper mould section and the two split sections, and telescopic springs are arranged in the two opposite blind holes;

the lower half body is identical to the upper half body in structure.

Preferably, the method comprises the following steps: the upper half body and the lower half body are made of alloy materials through heat treatment.

Preferably, the method comprises the following steps: the split parts of the upper half body and the lower half body are provided with positioning parts at the contact positions.

Preferably, the method comprises the following steps: the positioning part is characterized in that a bulge is arranged at the split bottom of the upper half body, and a groove is arranged at the position, corresponding to the bulge, of the split of the lower half body.

Compared with the prior art, the utility model has the advantages of: in last halfbody, the last mould lamella of taking the slot, the split of taking the inserted block is formed by whole cutting, and the rigidity of inserted block and split, intensity are identical completely, and owing to form by the cutting, go up the size precision and the direction precision homoenergetic of mould lamella and split and obtain guaranteeing, and need not to set up the guide bar alone and set up the guide way, have reduced the use material in the instrument, have practiced thrift man-hour and cost of processing, have improved the life of mold core.

Drawings

FIG. 1 is a schematic diagram of a prior art structure;

FIG. 2 is a schematic view of a prior art split configuration;

fig. 3 is a schematic structural diagram of the present invention.

In the figure: 1. feeding a mold half; 2. a lower mold half; 3. splitting; 4. a guide bar; 5. a tension spring; 6. inserting a block; 7. a slot; 8. a protrusion; 9. and (6) a groove.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Example 1: referring to fig. 1 to 2, a mold core for crimping a socket pressing pipe fitting in the prior art comprises an upper half body and a lower half body, wherein the upper half body is composed of an upper mold half 1 and two split parts 3, and the lower half body is composed of a lower mold half 2 and two split parts 3; two split 3 of last halfbody are equipped with guide bar 4 towards the one side of last mould lamella 1, and the department that goes up mould lamella 1 and correspond guide bar 4 is equipped with the guide way, and when pressing half upper and lower halfbody, guide bar 4 stretches into in the guide way. When the upper half body and the lower half body are separated, the guide bar 4 is protruded from the guide groove. The guide rod 4 with the structure is separately processed on the split 3, the rigidity and the strength of the guide rod are greatly different from those of the mold core, and the guide rod 4 is easily broken in use when the size of the guide rod is different from that of the guide groove.

Referring to fig. 3, the die core for press-connecting the socket pressing pipe fitting comprises an upper half body and a lower half body, wherein the upper half body is composed of an upper die half 1 and two split parts 3, and the lower half body is composed of a lower die half 2 and two split parts 3;

in the upper half body, a slot 7 is respectively arranged on the contact surface of the upper mold half 1 and the two corresponding split parts 3, an inserting block 6 matched with the slot 7 is arranged at the position, corresponding to the slot 7, on the top of each split part 3, the upper mold half body is an integral body, the upper mold half 1 with the slot 7 and the split parts 3 with the inserting block 6 are integrally cut, blind holes are respectively arranged on the opposite surfaces of the upper mold half 1 and the two split parts 3, and telescopic springs 5 are arranged in the two opposite blind holes;

the lower half body is identical to the upper half body in structure. The upper half body and the lower half body are made of alloy materials through heat treatment, wherein the alloy materials are low alloy materials 42CrMo or 9CrSi. The split parts 3 of the upper half body and the lower half body are provided with positioning parts at the contact positions. The positioning part is characterized in that a bulge 8 is arranged at the bottom of the split 3 of the upper half body, and a groove 9 is arranged at the position, corresponding to the bulge 8, of the split 3 of the lower half body.

The utility model discloses an in the last half body, take slot 7 go up mould lamella 1, take split 3 of inserted block 6 to form by whole cutting, each part is no matter the rigidity, intensity is all completely unanimous, and because form again by the cutting, goes up mould lamella 1 and split 3's size precision and direction precision homoenergetic and obtains guaranteeing, need not to set up guide bar 4 alone and set up the guide way like prior art's structure. The expansion spring 5 has a guiding effect here, and assists the opening and closing of the mould core.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
