The specific embodiment

Shown in Fig. 1～3, a kind of handle mould comprises cope match-plate pattern 30 and lower bolster 40, this mould also comprises punch 10 and die 20, punch 10 is fixed on the below of cope match-plate pattern 30, and die 20 is fixed on the top of lower bolster 40, the protuberance 11 of described punch 10 and recess 21 tablings of die 20.

By as can be known aforementioned, the utility model becomes the mould extrusion modling with the section bar to be processed of handle by the machined moulding, has not only improved production efficiency greatly, has also greatly reduced the generation of waste material, has saved raw material.

Shown in Fig. 1～3, the protuberance 11 of described punch 10 is tabular downward protrusion, the recess 21 of die 20 is the groove shape that matches with tabular protuberance 11, and the length of described protuberance 11 matches less than the length of recess 21 or with the length of recess 21, and protuberance 11 matches with the width of recess 21.

The above-mentioned the utility model that is arranged so that can be made the handle of vertical bar shape, and perhaps making both sides is crimp, and intermediate body member is the handle of vertical bar shape.

Described die has multiple implementation, as preferred version of the present utility model, described die 20 comprises and the ejecting core 23 and be fixed on stopping means on the lower bolster 40 of described protuberance 11 tablings, stopping means is arranged on the outside that ejects core 23, ejecting core 23 can move along the direction that stopping means limits, and ejects core 23 and constitutes described recess 21 with the hollow bulb that stopping means centers on.

Stopping means not only is easy to make handle machine-shaping with the setting that ejects core 23, and owing to eject core 23 and can move along the direction that stopping means limits, therefore the handle after the completion of processing also can successfully withdraw from mould, helps improving the production efficiency of product processing.

Described stopping means also has multiple implementation, be set in the external member that ejects around the core 23 such as employing, as preferred version of the present utility model, described stopping means comprises clamping plate 24 and the guide plate 22 that is fixed on the lower bolster 40, clamping plate 24 are arranged on the both sides that eject core 23, and guide plate 22 is arranged on the two ends that eject core 23, and the below that ejects core 23 is provided with the push rod 41 that places lower bolster 40, push rod 41 can promote to eject core 23 and move upward along the direction of its qualification, shown in Fig. 1～3.

Clamping plate 24 and guide plate 22 be arranged on eject core 23 around, both helped the machine-shaping of handle, help the maintenance of this mould again, the cross section of the clamping plate 24 described in the figure is L-shaped, also helps it and is fixed on the lower bolster 40.As shown in Figure 2, owing to be provided with push rod 41 in the lower bolster 40, after handle machine-shaping, push rod 41 moves upward, and ejects core 23 and also follows and move upward, and the handle of therefore being convenient to after the machine-shaping withdraws from mould.The described end face size that gets push rod 41 can be identical with the bed-plate dimension that ejects core 23 or more smaller than it, when the end face size of push rod 41 than the bed-plate dimension that ejects core 23 slightly hour, eject core 23 and can be located in simultaneously on lower bolster 40 and the push rod 41, can better carry the stamping press of punch 10.

The protuberance 11 of described punch 10 matches with the interior molded dimension L1 of handle, and the recess 21 of die 20 matches with the overall dimensions L2 of handle, and the length of described recess 21 is than the little 0.3～0.7mm of overall dimensions L2 of handle, as shown in Figure 4.

The interior molded dimension L1 of described handle is meant the dead size between the two crimp inside of handle, and overall dimensions L2 is meant the outermost size between two crimps of handle.Described protuberance 11 and recess 21 match with the interior molded dimension L1 and the overall dimensions L2 of handle respectively, are convenient to produce the handle that meets people's expectation.The length of described recess 21 is than the little 0.3～0.7mm of overall dimensions L2 of handle, helps preventing the rebound phenomenon after the handle machine-shaping.

As preferred version of the present utility model, described protuberance 11 coincides with the axis along pressing direction of recess 21, as shown in Figure 1.

This setup makes that the crimp of handle both sides is symmetrical fully about the center line of handle, thereby makes gained handle good looking appearance, is convenient to grip.

As preferred version of the present utility model, the width of the recess 21 of described die 20 is than the little 0.3～0.7mm of width of section bar 50 to be processed, as shown in Figure 2.

Section bar to be processed is when bending, because the skin of section bar in the bending place be subjected to stretching action, internal layer is compressed effect, therefore the outer layer thickness attenuate can occur and situation that internal layer thickens, also be that handle diameter does not everywhere wait, thereby seriously influenced the appearance of handle.As shown in Figure 2, because the width of the utility model center dant 21 is littler than the width of section bar 50 to be processed, also be to be negative clearance between mould and the section bar to be processed, therefore the preceding section bar 50 to be processed of processing can be placed into the top of recess 21.Add man-hour, as shown in Figure 3, described protuberance 11 is squeezed to section bar to be processed the bottom of recess 21 under the effect of forcing press, and under the form fit of aforesaid protuberance 11 and recess 21, not only appearance is good but also compactness good for processing gained handle simultaneously.

As the further preferred version of the utility model, the width of the recess 21 of described die 20 is than the little 0.5mm of width of section bar 50 to be processed.

0.5mm negative clearance gained handle superior in quality, be easy to realize and the working (machining) efficiency height.

Section bar 50 to be processed has multiple choices, and aluminium section bar or aluminium alloy extrusions are elegant in appearance, and cost is lower and be convenient to processing, is preferred selection of the present utility model.

As preferred version of the present utility model, as shown in Figure 1, between the base along its length of described recess 21 and the dual-side of its upright plate face of living in is round-corner transition, also be round-corner transition between the base along its length of protuberance 11 and the dual-side of its upright plate face of living in, the radius of curvature at the round-corner transition place of described recess 21 greater than with the radius of curvature at the round-corner transition place of its corresponding protuberance 11.

Aforesaid bent angle transition makes the handle of machine-shaping not only be convenient to grip, and appearance is better.

As further preferred version of the present utility model, the radius of curvature at the radius of curvature at the round-corner transition place of described recess 21 and the round-corner transition place of corresponding protuberance 11 poor, equate that with the tip spacing of protuberance 11 and recess 21 tip spacing of the rear and front end of protuberance 11 and recess 21 also all equates.

Owing to all equate between the difference of recess 21 and the fillet radius of curvature of protuberance 11 and the tip spacing three of the rear and front end of protuberance 11 and recess 21, also promptly make the diameter everywhere of the utility model processing gained handle all can equate, further promoted the appearance of handle thus.
