Description

For being molded the mould slide block structure of bimetallic insulation inserts

Technical field

It the utility model is related to mold design field, and in particular to a kind of mould for being used to be molded bimetallic insulation inserts is slided Block structure.

Background technology

Injection is to develop faster few cutting, the process without cutting in modern mechanical manufacturing, and plastics are in injection pressure Under effect, it is pressed into metal mold cavity, die cavity is full of, obtains clear-cut, any surface finish, be consistent with injection die cavities and can be with The moulding of exchange.According to the difference of injection molding product structure, in mold design, used parting methods and mold cavity Structure is also different.

Bimetallic insulation inserts product is one kind in injecting products, and it includes outer metal housing 6, metal-cored 8 and parcel The ambroin body 7 being wrapped in outer metal housing 6 and by metal-cored 8 inside it（As shown in Figure 1）.Insulated for bimetallic For the product of inserts, it is necessary to which metalwork is placed in mold cavity during injection, then noted again into metalwork Enter the plastics for being heated and melting.For this product, during mold design, it is necessary to by the outline of mold cavity and outside The outline of metal-back matches, while, it is necessary to outer metal housing and metal-cored positions.However, for tapered For outer metal housing, because the precision of this metal-back is relatively low, during matched moulds, outer metal housing just easily because precision is low and with Mould assembling is difficult, meanwhile, during matched moulds, metalwork easily produces collision, mold damage with sliding block.

The content of the invention

For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is：

When the inserts product that insulated to bimetallic carries out mold design, because metalwork band is tapered, its precision is relatively low, leads Cause metalwork assembling difficulty, meanwhile, during mould matched moulds, metalwork easily produces collision, mold damage with sliding block.

In order to solve the above-mentioned technical problem, the utility model employs following technical scheme：

A kind of mould slide block structure for being used to be molded bimetallic insulation inserts, it includes cover half and be arranged on cover half two Individual dynamic model sliding block, two injection dynamic model die cavities are arranged with each dynamic model sliding block, it is characterised in that the dynamic model die cavity It is interior that there is outer metal housing placed cavity, it is provided with an outwardly step in the middle part of the scalene cone of outer metal housing placed cavity, described Rank height of projection is at least 2mm, and step is close to moulding forming cavity.By in the middle part of the outer metal housing placed cavity of dynamic model die cavity One step is set, it is possible to increase the placement space of outer metal housing, also can be by outer metal in the case that its taper accuracy is bad Shell can be put into, meanwhile, the setting causes during matched moulds space between outer metal housing and sliding block be present, the formation in the space It is avoided that outer metal housing collides in matched moulds and when dividing mould with sliding block, mold damage.

Further, the dynamic model sliding block is located at the left and right sides of cover half respectively, and by Angle Pin, left and right is moved on cover half Dynamic, realization divides mould and matched moulds.Drive two dynamic model sliding blocks to distinguish phase both sides by Angle Pin to move, can realize sliding block divide mould and Matched moulds, meanwhile, after dividing the movement of dynamic model sliding block to mould, the bimetallic inserts product being molded is i.e. on the inside of sliding block, with cover half shape Into certain gap, so as to more convenient product stripping.

Further, running gate system, the running gate system are equipped with the middle part of each dynamic model sliding block, between two dynamic model die cavities It is connected including vertical sprue, with sprue and is in the runner and two one end and runner end phase that laterally set Connection, the cast gate that is connected with dynamic model die cavity of the other end, the cast gate are located at the upper of moulding forming cavity bottom in dynamic model die cavity End.Cast gate is arranged on to the top of moulding forming cavity, so that the lower section stream of the driven model cavity of plastic solution after heating Dynamic top, so that plastic solution is full of whole moulding forming cavity, be not in dead angle, meanwhile, it will not also be pointed to type Core impacts, and influences insulation effect.

Compared with prior art, what the utility model obtained is used to be molded the mould slide block structure tool of bimetallic insulation inserts Have the following advantages：

1. by setting a step in the middle part of the outer metal housing placed cavity of dynamic model die cavity, it is possible to increase the placement of outer metal housing is empty Between, outer metal housing be able to can be also put into the case that its taper accuracy is bad, meanwhile, the setting causes in matched moulds process In, space between outer metal housing and sliding block be present, the formation in the space is avoided that outer metal housing in matched moulds and when dividing mould and sliding block Collide, mold damage.

2. driving two dynamic model sliding blocks to distinguish phase both sides by Angle Pin to move, that realizes sliding block divides mould and matched moulds, so that It is more convenient to obtain the product stripping after injection molding.

3. cast gate is arranged on to the top of moulding forming cavity, so that the driven model cavity of plastic solution after heating Flowing underneath above be not in dead angle so that plastic solution is full of whole moulding forming cavity, meanwhile, also will not It is pointed to core to impact, influences insulation effect.
