Abstract

A special spanner of an injection head of a plastic encapsulated mould is provided with a pivot element consists of a ratchet wheel, a detent, a clamp body, a baffle and a handle. The center of the ratchet wheel is provided with an inner dodecagonal inner hole. The spanner is also provided with a Haff jacket as the transition unit, the two half Haff jackets are folded to form a dodecagonal outer circle which meshes the inner dodecagonal inner hole at the center of the ratchet wheel. The center of the spanner is an inner sexangular hole, which meshes a six rectangular unit of an injecting rod of the injection head components. When the special spanner is used, the injecting rod can be just put into the Haff jacket, and then the pivot element is mounted into the Haff jacket of the injecting rod, and each component of the injection head can be screwed loosely or screwed firmly. The use is simple, convenient, practical and efficient.

Description

A kind of plastic sealed mould injection head special spanner

(1) technical field

The utility model belongs to the plastic sealed mould field of microelectronic industry, specifically a kind of special spanner of plastic sealed mould injection head.

(2) background technology

At present, in the plastic sealed mould field, single cylinder type plastic sealed mould is changed frequent in usual the use with the injection head assembly.Because the retaining width is opened only between 120-130mm in mould blowing porch, can't activity when adopting general conventional spanner operation because of opening that shelves are little, at this moment, have to be with the mould closure, shedding on all mold pressing then pulls, the certain distance that again unitary mould descended, reserve with the upper table useful space routinely program loosen, tighten the injection head assembly.Behind the EO,, make the mould homing, use pressing plate fastening more again with the lathe closure.This shows that it is time-consuming to finish the overall process of changing the injection head assembly, very trouble.

(3) summary of the invention

The purpose of this utility model is to provide a kind of plastic sealed mould injection head special spanner, and it adopts single direction ratchet to transmit torsion, and transfers torque on the injection head assembly by the Hough chuck again.Reach effect convenient, laborsaving, that exempt the dismounting mould.

By a kind of plastic sealed mould injection head special spanner that the utility model proposes, its main part by ratchet, ratchet, clamp body, shelves are pulled and handle is formed, and in ratchet central authorities, the endoporus of 12 dihedrals in are set; Other has a transition piece is the Hough chuck, and its profile is that the interior 12 dihedral endoporus of outer 12 dihedrals and ratchet central authorities are meshed, and is that the hexahedron of inner hexagonal hole and injection head assembly injection rod is meshed in the middle of it.

Be explained in detail this reality is novel below in conjunction with accompanying drawing embodiment.

As shown in Figure 1, main part of the present utility model is the clamp body of band ratchet, and the central authorities in clamp body (2) are equipped with a single direction ratchet (1), and pull (3) with two retainings ratchet (1) is clamped, retaining is pulled (3) and is fixed on the clamp body (2) by screw (7).Central authorities in ratchet (1) are provided with the endoporus (9) of 12 dihedrals in.On one side of ratchet, ratchet (4) is installed, and has spring (5) to be used for withstanding ratchet, fix spring (5) by plug screw (8).In the lower end of clamp body, handle (6) is housed, its length with handled easily for well.

Because injection head work head is bigger than the injection rod diameter of rear end, above-mentioned special spanner can't directly be inserted in use, therefore designed a transition piece Hough chuck (10), the Hough chuck of two halves back periphery altogether is outer 12 dihedrals, and the interior 12 dihedral endoporus of ratchet (1) central authorities are meshed, its central authorities are inner hexagonal hole, are meshed with six side's parts on the injecting assembly injection rod.

When operation, only need the ratchet of special spanner is inserted in the injection head injection rod, and then divide two halves to be respectively charged into ratchet central authorities the Hough chuck, fasten the hexahedron of injection rod, can tighten or unscrew effect, because A, the B of injection head work head, the surperficial hexahedron consistent size at C three places therefore can be easily with above-mentioned three parts with this special spanner, promptly connector (11), adapter sleeve (12) and connecting rod (13) unload or load onto.

Use this special spanner, can very easily plastic sealed mould injection head assembly and each several part be unloaded or load onto, and other parts that needn't remove mobile injection moulding lathe and mould, therefore, realized simple, convenient, practical, purpose efficiently.

(4) description of drawings

Accompanying drawing 1a, b are main body of the present utility model---the clamp body structural representation of band ratchet, wherein b is the side view of a.

Accompanying drawing 2 is the structural representation of the utility model transition piece Hough chuck.

Accompanying drawing 3 is a plastic sealed mould injection head modular construction schematic diagram, and the outer cross section on A, B, surface, C three place is outer-hexagonal shape.

(5) specific embodiment

The injection head assembly of accompanying drawing 3 is a kind of float type construction packages with plastics king sealing ring, therefore, before this special spanner is inserted in this assembly, all can put into the Hough chuck at A, B or C three places, easily each assembly is dismantled with special spanner then.In the whole operation process, by handle power is passed to ratchet by ratchet, make ratchet do counterclockwise rotatablely moving, by the Hough chuck injection head assembly is tightened; When clockwise rotation is made in reverse installation, the injection head assembly is unscrewed.

Claims (2)

1, a kind of special spanner of plastic sealed mould injection head, it is made up of ratchet, ratchet, clamp body, baffle plate, it is characterized in that the main part structure is that two baffle plates are clamped ratchet, and baffle plate is fixed on the clamp body by screw, in the central authorities of ratchet, be provided with the endoporus of 12 dihedrals in; Other has a transition piece is the Hough chuck, and the Hough chuck of two halves back periphery altogether is that the endoporus of interior 12 dihedrals of 12 dihedrals and ratchet central authorities is meshed, and the central authorities of Hough chuck are inner hexagonal hole, is meshed with six side's parts on the injection head assembly injection rod.

2, by the special spanner of the described a kind of plastic sealed mould injection head of claim 1, it is characterized in that lower end, handle is housed at clamp body.
