Abstract
The utility model relates to improvement on plastic moulds, and provides an ejecting plate reset confirming mechanism for a plastic mould, and the mechanism ensures the reliability of a mould closing action, and can be avoiding the damages to an upper mould, and prolonging the service life. The plastic mould comprises lower templates, a pair of cushion blocks, a bottom plate, an ejecting plate, a return pin and springs, wherein the pair of cushion blocks are arranged on the bottom plate; the lower templates are arranged on the pair of cushion blocks; the ejecting plate is horizontally arranged between the pair of cushion blocks and is positioned between the lower templates and the bottom plate; one end of the return pin is fixedly connected to the ejecting plate; the other end of the return pin passes through the lower template; the springs are sleeved on the return pin and between the lower templates and the ejecting plate; the mechanism also comprises a reset confirming mechanism which comprises a microswitch and a return switch contacting block; the microswitch is arranged on the bottom plate; and the return switch contacting block is arranged on the ejecting plate and is opposite to the microswitch. The mechanism has a simple structure, and is convenient and reliable.
Description
Technical field
The utility model relates to the improvement of plastic mould.
Background technology
Plastic mould is a kind of sectional die through injection molding product, and the variable impression of forming between the upper and lower mould can satisfy
The plastic part of difformity, different size.The production procedure of plastic mould is roughly matched moulds, injection moulding, formed product and divides mould to eject to product, arrives the matched moulds state again, and so reciprocal operation manufactures a finished product.In the matched moulds process, ejector retainner plate resets earlier, accomplishes the matched moulds state then; Wherein ejector retainner plate exists ejector retainner plate to fail to get back to appointed positions (comprising the reason that spring damage etc. causes) usually, and carries out matched moulds by force when resetting, and easily patrix is damaged, and causes damage.
The utility model content
The utility model is to above problem, provides a kind of and guarantees the mould assembling action reliability, avoided patrix to break, the plastic mould top board that the improves service life confirming mechanism that resets.
The technical scheme of the utility model is: said plastic mould comprises lower bolster, a pair of cushion block, base plate, top board, back stitching and spring,
Said a pair of cushion block is located on the said base plate, and said lower bolster is located on the said a pair of cushion block, and said top board level is located between the said a pair of cushion block, and between said lower bolster and base plate;
Said back stitching one end is fixedly connected on the said top board, the other end runs through said lower bolster;
Said spring housing is located on the said back stitching, is located between said lower bolster and the top board;
Also comprise the confirming mechanism that resets, the said confirming mechanism that resets comprises microswitch and return switch contact block,
Said microswitch is located on the said base plate, and said return switch contact block is located on the said top board and corresponding said microswitch.
Offer groove in said lower bolster bottom, said spring is embedded in said groove.
Also comprise the rubbish nail, said rubbish nail fixedly is located at the bottom surface of said top board.
The utility model is provided with the top board confirming mechanism that resets on the counterdie of plastic mould, promptly microswitch is located on the base plate, and return switch contact block is located on the top board.Mould is after ejecting product, and under the effect of spring, top board begins to reset; When the return switch contact block on the top board touches the microswitch on the base plate, promptly confirm the top board return, begin to feed back signal to the injection moulding board then; After board receives signal, carry out mould assembling action.The utility model is simple in structure, and is convenient and reliable.
