Abstract
The utility model provides a taper pin structure which comprises a taper pin and a taper pin hole, wherein the taper pin and the taper pin hole are arranged on a lower die holder; and the taper pin structure is characterized in that the cross section of a taper pin rod of the taper pin is in the shape of a Chinese character 'ao', in the shape of a Chinese character 'tu', arc-shaped or cross-shaped, and the cross section of the taper pin hole for accommodating the taper pin is correspondingly set as a hole slot which is in the shape of a Chinese character 'ao', in the shape of a Chinese character 'tu', arc-shaped or cross-shaped. Lots of inserts or attachments are arranged in the existing die usually, for arranging the inserts or attachments, corresponding hole slots are dug in the die holder, so that the bearing force of the die holder is reduced. The utility model provides a novel taper pin structure for replacing the traditional square taper pin rod, so that the volume of an open slot of the die holder is reduced.
Description
Technical field
The invention belongs to mould applications, be specially a kind of Novel angle pin structure that is applied in the mould.
Background technique
Usually a lot of annexes, mold insert etc. can be set in the existing mold; for these annexes or mold insert are set at mould, die holder is offered corresponding hole slot or passage in template or die, but has correspondingly reduced the bearing area of template or die; can cause the bearing capacity of die holder to reduce, equipment easily is damaged.Taper pin is a kind of annex in the mould, as the aspects such as edge forming face of bundle piece, liftout mechanism or molding product.
Summary of the invention
Technical purpose of the present invention provides a kind of Novel angle pin structure, reduces the unnecessary perforated area of die holder.
Technological scheme of the present invention:
A kind of inclined pin structure, comprise the taper pin and the pin hole that are arranged on the die set, it is characterized in that, the taper pin bar cross section of described taper pin be " recessed " shape, " protruding " shape, arc or cross in a kind of, correspondingly be made as cross section as the pin hole of accommodating described taper pin and be " recessed " shape, " protruding " shape, arc or cross hole slot.
Described taper pin comprises mold insert, and described mold insert and taper pin are formed in one or the head that is fixed on taper pin with bolts.
When mold insert and taper pin non-when one-body molded, described mold insert bottom is provided with the joint that docks with taper pin, establish the cavity that agrees with mutually with the taper pin nose shape in the described joint, after mold insert is enclosed within on the described taper pin, the taper pin head is embedded in the cavity of joint, adopts necessary means of fixation further fixing again.
The hole slot wall of described pin hole is provided with wear plate.
Beneficial effect of the present invention:
The present invention removes the partial volume of shaft on the basis of existing square or cylindricality taper pin bar, reduce the volume that shaft takies, and has namely correspondingly reduced the cavity that holds that die holder need to offer, and increases the bearing area of die holder upper die plate etc.Simultaneously, further adopt the mode of engaging to connect mold insert, make things convenient for the replacing of mold insert.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention one;
Fig. 2 is the structural representation of the embodiment of the invention two.
Embodiment
In order to illustrate technological scheme of the present invention and technical purpose, below in conjunction with the drawings and the specific embodiments the present invention is done further introduction.
As shown in the figure, a kind of inclined pin structure, comprise the taper pin and the pin hole that are arranged on the die set, the taper pin bar cross section of described taper pin be " recessed " shape, " protruding " shape, arc or cross in a kind of, correspondingly be made as cross section as the pin hole of accommodating described taper pin and be " recessed " shape, " protruding " shape, arc or cross hole slot.
Shown in Figure 1 is one " protruding " type taper pin bar, and it has removed two corner angle of shaft, as shown in Figure 2, is one " recessed " type taper pin bar, offers the groove of up/down perforation from a side of shaft.Above-mentioned mode of execution has all kept long, the widest length in shaft cross section.
Described taper pin also comprises mold insert, described mold insert and taper pin are formed in one, perhaps can with boltsly be fixed on the head of taper pin, the mold insert bottom is provided with the joint that docks with taper pin during connection, establish the cavity that agrees with mutually with the taper pin nose shape in the described joint, after mold insert was enclosed within on the described taper pin, the taper pin head was embedded in the cavity of joint.
The hole slot wall of described pin hole is provided with wear plate, prevents that taper pin from sliding up and down in the process wearing and tearing to template.
More than show and described basic principle of the present invention, major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
Claims (4)
1. inclined pin structure, comprise the taper pin and the pin hole that are arranged on the die set, it is characterized in that, the taper pin bar cross section of described taper pin be " recessed " shape, " protruding " shape, arc or cross in a kind of, correspondingly be made as cross section as the pin hole of accommodating described taper pin and be " recessed " shape, " protruding " shape, arc or cross hole slot.
