Description

A kind of sealing shroud molding die

Technical field

The utility model relates to sealing shroud manufacturing fields, more particularly, to a kind of sealing shroud molding die.

Background technique

It is the polytechnic general name of plastic products that plastic processing, which is by synthetic resin or converting-plastics, is in plastics industry One biggish production division.Plastic processing generally comprises ingredient, molding, machining, engagement, modification and the assembly of plastics Deng.Four processes are carried out after plastics are molded for product or semi-products afterwards, also known as plastics secondary operation.

Plastic processing is as the development of synthetic resin gets up, and the development of it and plastics machinery promotes mutually. Many plastic processing technologies are to be referred from rubber, metal and Ceramic manufacturing.Plastic processing history can be traced to 90 years 19th century After celluloid is born, because its is inflammable, block can only be made, then machined at sheet material, sheet material is available in generation of die pressing Hot-forming method processing.This is earliest plastic processing.Cast molding is studied successful as phenolic resin comes out；It is injected into Type starts from the 1920s, for processing cellulose acetate and polystyrene；The mid-1930s, flexible PVC extrusion molding It succeeds in developing, the dedicated single screw extrusion machine of plastics accordingly comes out；Double screw extruder also puts into production within 1938.The forties Just, polyurethane foam plastics has been produced, blow molding technology is for producing polyethylene hollow product.Nineteen fifty-two reciprocating screw type injector It comes out, injection molding technology is made to enter a new stage.60~seventies, the plastic processing technology that new development is got up have: The various new forming methods of reinforced plastics, such as winding, pultrusion, sheet molding molding, reaction injection molding, structural foam form, are different Section bar extrusion molding, sheet material solid phase forming and coextrusion, co-injection etc..Into the eighties, plastic processing is towards efficient, high Speed, high-precision, energy saving, the enlarged or directions such as extra small, ultra-thin are developed, and computer technology enters this field, entire plastics Processing technology is increased to a new height.

The key link of plastic processing.Required shape is made in the plastics (powder, pellet, solution or dispersion) of various forms Product or blank.Up to thirties kinds of molding method.Its selection depends mainly on type (thermoplasticity or the heat of plastics Solidity), starting form and product shape and size.The common method of processing thermoplastic plastics has extrusion, injection moulding, pressure Prolong, be blow molded and thermoforming etc., processing thermosetting plastics are generally using molding, transfer modling, also with injection moulding.Lamination, molding It is to form plastics in the plane with thermoforming.The method of above-mentioned plastic processing, is used equally for rubber processing.In addition, there are also with Liquid monomer or polymer are the casting etc. of raw material.In these methods, with the most use with extrusion and injection molding, and most base This forming method.

It is as shown in Figure 1 a plastic seal nested structure, existing sealing shroud is formed by mold, in existing mold, The structure of mold inner template is complex, and development cost is higher, and care and maintenance is inconvenient, now redesigns and develops a sealing Sleeve forming mold.

Summary of the invention

The technical problem to be solved by the utility model is to provide a kind of structure is simple, reasonable sealing shroud shaping mould is designed Tool.

Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of sealing shroud molding die, including Feedboard, cope plate and lower template, the feedboard are equipped with the first material path, and the lower template is equipped with 12 rounded moulds Slot, 12 die cavitys are distributed with the matrix structure of three column, four row, the cope plate bottom be equipped with 12 it is cylindrical Mold core, 12 mold cores are adapted with 3 × 4 matrix structure, the mold core and die cavity, when the cope plate It is molded with lower template, the mold core insertion die cavity constitutes die cavity, is equipped with runner plate, the runner between adjacent two column die cavity Plate is connect with lower template, and the runner plate is equipped with several second material paths, and the runner plate side is equipped with the recessed of semicircle shape Mouthful, the recess is stuck on mold core, second material path and mould cavity, first material path and the second material path phase It is logical.

Compared with prior art, the utility model has the advantage of simple structure and reasonable design, easy to maintain and maintenance, Multiple sealing shrouds can be molded.In simple terms, melt flows into each second material of runner plate from the first material path in feedboard In road, melt flows into each die cavity from the second material path form again.
