Abstract
The utility model discloses a plastic mould which comprises a jacking part; and a plurality of air discharge ducts, oil stain slots and a plurality of oil baths are formed in the jacking part. A product which is manufactured through the mould has no oil stain, has greatly improved quality, and thus meets the needs of a plurality of industries.
Description
Technical field
The utility model relates to a kind of mould.
Background technology
Mould of plastics is in the plastic processing industry and plastic molding press is supporting, gives the instrument of plastic products with complete configuration and accurate dimension.Because plastics variety and processing method are various, the structure of plastic molding press and plastic products is complicated and simple differing again, so the kind of mould of plastics and structure also are diversified.
A kind of built-up plastics mould for compression moulding, extrusion molding, injection, blowing and low foaming, it mainly comprises the die with variable impression that is comprised of die assembled substrate, die assembly and die combination clamp, by punch assembled substrate, punch assemblies, punch make up clamp, die cavity blocks assembly and side is cut the punch with variable core that compoboard forms.Mould punch and matrix and assistant formation system coordination change.Can process the serial plastic of difformity, different size.Supporting with plastic molding press in the plastic processing industry, give the instrument of plastic products with complete configuration and accurate dimension.Because plastics variety and processing method are various, the structure of plastic molding press and plastic products is complicated and simple differing again, so the kind of mould of plastics and structure also are diversified.
Develop rapidly and general and engineering plastics improving constantly at aspects such as intensity and precision along with plastics industry, the range of application of plastic products is also in continuous expansion, and the shared ratio of plastic products just rapidly increases. and a working of plastics reasonable in design often can replace a plurality of traditional metal parts. and the consumption of plastic product also rises.
Mould of plastics is a kind of instrument of producing plastic products. it partly is made of several groups of parts, in this combination shaping mold cavity is arranged. during injection moulding, clamping mould is on injection machine, molten plastic is injected in the shaping mold cavity, and in the chamber cooling and shaping, then upper and lower mould separately ejects goods via ejection system and to leave mould from die cavity, last mould again closure carries out next time injection moulding, and whole injection moulding process loops.
The structure of mould of plastics and basic part:
The structure of blow molding die, draw mould and thermoforming mould is comparatively simple.
Compression mould, injection mould and biography mold structure are comparatively complicated, and the part that consists of this class mould is also more.
Basic part has:
1. forming part comprises die, punch, various forming core, all is the inside and outside surface of moulded products or upper and lower end face, side opening, side is recessed and the part of screw thread.
2. support retaining element, comprise die holder plate, fixed head, support plate, cushion block etc., in order to fixed mould or support pressure.
3. guide elements comprises guide pillars and bushes, in order to determine the relative position of mould or ejecting mechanism motion.
4. the part of loosing core comprises taper pin, slide block etc., in order to extract moving core out, makes the goods demoulding when mold open.
5. release part, comprise push rod, ejector sleeve, pushing block, push piece plate, stripper ring, ejector pin retaining plate, push pedal etc., use so that the goods demoulding.Injection mould is promoted the employing standard die set more, and this mould bases is that all the basic part of standardization and seriation is complete combines by structure, form and size, and its die cavity can be processed voluntarily according to article shape.Adopt standard die set to be conducive to shorten the moulding cycle.
Acting as of each part:
Top clamping plate (panel): its effect is that front mould is fixed in the above.
Runner plate (water gap plate): its effect is exactly when die sinking the material in the runner to be removed.
The cover half fixed head: its Main Function is and b plate together shaped article.
Push pedal: its Main Function is when die sinking product to be deviate from from mould.
Dynamic mould fixing plate: its Main Function is and a plate together shaped article.
Backing plate: its effect is to strengthen the intensity of a plate and fixing some parts on a plate.
Cushion block: mould pin, square iron etc.Its effect is to allow top board that enough activity spaces are arranged.
Top board: its Main Function be fixedly thimble and when die sinking the push rod by injector promote thimble.
Bottom clamp plate: lower plate, base plate etc.Its Main Function is that rear mold is fixed in the above.
Guide pillars and bushes: their Main Function is to play the guiding role, and mould can be finished all actions smoothly before and after making.
Thimble: its Main Function is when injection is finished mould and opened product to be ejected from Die.
Present stage, plastic containers incorporated the every aspect of people life gradually, but present mould of plastics is when producing product, the movable position of mould can produce a little greasy dirt, for requiring stricter industry such as food, the industries such as medical treatment, can cause very to seriously influence, therefore how improve mould, be the problem that urgent need will solve to produce qualified product.
Summary of the invention
Because the problems referred to above of prior art the utility model proposes a kind of die ejection system scheme, it can effectively solve the problems referred to above of prior art.
The utility model addresses the above problem by the following technical programs:
A kind of mould of plastics, it contains and ejects part, this eject part be provided with some air discharge ducts, greasy dirt groove, and some oil grooves and these grooves the certain size requirement is arranged.
The described part that ejects is that push rod, push pipe, jacking block, top board, apical ring, thimble etc. are a kind of.
Described push rod comprises the first push rod and the second push rod, and this first push rod is provided with an air discharge duct, and described the second push rod is provided with a greasy dirt groove and an oil groove.
The utlity model has following advantage:
By the mould product that this die ejection system is produced, without greasy dirt, it is greatly improved qualitatively, thereby has satisfied the needs of many industries.
