Abstract

The utility model discloses a plastic mold utilizing a conical sliding block to position an insert for shaping, and belongs to the field of thermoplastic plastic forming molds. The inside of the mold mainly structurally comprises a fixed die inserting block, a movable die inserting block, an insert sleeve, an ejector rod sleeve, the conical sliding block, a sliding block spring, a spring guide pin, a back plate of the sliding block, a conical ejector rod, a delayed ejector rod, the insert and the like, wherein the insert sleeve is provided with a positioning flat piece and a hanging table which are connected with that of the movable die inserting block to prevent the rotation of the movable die inserting block in XY direction; and the hanging table of the insert sleeve and a hanging table hole in the movable die inserting block, are positioned in Z direction; the conical sliding block is in tight matching with the inner periphery of the movable die inserting block and can slide in an inner track of the movable die inserting block; the conical sliding block is limited via the sliding block spring; and the spring guide pin is inserted into the sliding block spring to guide the spring to be in right position. In the utility model, the conical sliding block can limit the position of the insert through the matching of conical surfaces of the conical ejector rod and the conical sliding block to position the insert accurately, which simplifies the structure of the mold and improves production efficiency.

Description

A kind of mould of plastics by the inserts moulding of conical sliding block location

Technical field

The utility model belongs to the mould for plastics technical field, relate to and a kind ofly make inserts in mold cavity, accurately behind the location, carry out injection moulding, shaped article again by conical sliding block, when mold injection finished die sinking, the location of in advance removing inserts ejected the mould of plastics of product at last.Be mainly used in product to outward appearance and dimensional requirement strictness, and the structure of product is short of when mould molding in the mould of plastics of location benchmark.

Background technology

Present mould for moulding band inserts, and part does not participate in moulding in the inserts, and it is very strict and need pinpoint mould to the product appearance dimensional requirement, traditional way is that part that the inset part does not participate in moulding is made special-shaped sheath and positioned, manufactured parts cost and required precision are higher, and production efficiency is low.If before moulding by conical sliding block the inserts fine positioning, just solved above-mentioned shortcoming.

Summary of the invention

It is that the disposable fine positioning of the relative position in mould carried out shaping work again after inserts was installed that the utility model is wanted the technical solution problem.

The technical solution of the utility model is:

The mould bases of this mould comprises top clamping plate, cover half template, dynamic model template, square iron group, ejector pin retaining plate, push pedal and Bottom clamp plate, and the internal structure of mould comprises fixed die insert, moving die insert, inserts sleeve pipe, push rod sleeve pipe, conical sliding block, sliding block spring, spring pilot pin, slide block backboard, taper push rod, postpones push rod and inserts.

Fixed die insert 8 is embedded in cover half template 2 die cavities, is threaded, and by bolting, the cover half part of shaped article.Inserts sleeve pipe 10 has the flat and hanging platform in location to be connected with moving die insert 9 hanging platforms, limits its XY to rotation, and inserts sleeve pipe 10 hanging platforms and moving die insert 9 interior hanging platform hole Z are to the location.Push rod sleeve pipe 13 is connected with inserts sleeve pipe 10 hanging platforms, and conical sliding block 12 and moving die insert 9 interior closely cooperating in week can slide in its track, and conical sliding block 12 is spacing by sliding block spring 16, is inserted with spring pilot pin 17 in the sliding block spring 16, the correcting spring.Spring pilot pin 17 is fixed on the slide block backboard 18 by screw thread.Slide block backboard 18 is threaded with moving die insert 9, fixing whole conical sliding block mechanism.Taper push rod 15 cooperates with conical sliding block 12 taper surfaces is positioned in the inserts sleeve pipe 10 conical sliding block 12.Moving die insert 9 is embedded in cover half template 3 die cavities, is threaded, and by bolting, the dynamic model part of shaped article.

The beneficial effects of the utility model are to cooperate with the conical sliding block taper surface by the taper push rod to make conical sliding block restriction inserts position, make its accurate location, guarantee the product size requirement, have simplified the structure of mould, reduce cost, and have improved production efficiency.

The specific embodiment

Be described in detail the specific embodiment of utility model below in conjunction with technical scheme and accompanying drawing.

Fixed die insert 8 is embedded in the cover half template 2, and the reverse side bolt connects and is fixing.

The hanging platform of push rod sleeve pipe 13 is cooperated with inserts sleeve pipe 10, guaranteeing to postpone push rod 14 is not worn in the process of ejecting, the flat cooperation of flat location with moving die insert 9, the location of inserts sleeve pipe 10 imported wherein, cover pipe orifice accuracy tolerance needs within 0.005mm, prevent that resin from flowing in the sidewall of inserts 11 and inserts sleeve pipe 10, conical sliding block 12 is imported in the moving die insert 9, and two sides of conical sliding block 12 and moving die insert 9 are engaged in its track and slide.Conical sliding block 12 back sides import sliding block spring 16, and the position of conical sliding block 12 to the location resets behind the pressurized.Moving die insert 9 is embedded in the dynamic model template 3, and the reverse side bolt connects and be fixing, will postpone push rod 14 and be installed in the ejector pin retaining plate 5 with taper push rod 15.

Before the injection moulding inserts 11 is placed in the inserts sleeve pipe 10, inserts 11 has directionality, need to be with flat direction to import in the inserts sleeve pipe 10 inserts 11 towards the conical sliding block direction, can contact with conical sliding block 12 when inserts 11 enters into the sleeve pipe bottom up to conical sliding block and contact with the delay push rod, with inserts 11 location, the mould matched moulds carries out injection moulding fully.

After the die sinking, make-up machine ejects post promotion backing plate 6 and ejects, and the conical surface of taper push rod 15 heads cooperates with conical sliding block 12 inner conical surfaces skids off conical sliding block 12 direction along ng a paths.Remove the location with inserts 11, eject post and continue to eject, middle the hanging platform of time-delay push rod 14 cooperates with backing plate 5, makes the push rod 14 of delaying time that product is ejected the precalculated position, the product after the taking-up moulding, and this injection moulding finishes.
