Abstract
The utility model discloses an injection mold cooling system sealing plug, which includes a headless inner hexagon screw (1), a copper tube (2), a pull rod (3), and a sealing rubber (4), wherein the pull rod (3) is connectd to the headless inner hexagon screw (1) and the sealing rubber (4), characterized in that a copper tube (2) is added between the headless inner hexagon screw (1) and the sealing rubber (4), the entire structure is in a the font shape of 1. The sealing plug can be used in the sealing of injection mold cooling water channel, and has features of sealing, reliability, long life, and convenient demolition.
Description
Technical field
The utility model relates to the sealing means of mold cooling system pipeline, especially for the sealing of high temperature cooling medium.
Background technology
In order to accelerate moulding formed product cycle and the stable product quality of acquisition, the cooling of mould is vital.But because the fluctuating of the shape of product is indefinite, just cause the forming surface of mould also to follow the product fluctuating, in order to obtain cooling effect relatively uniformly, just have only the flow path of cooling water channel is is also risen and fallen with the shape of product, so just must on template, bore the hole of some intersections, and a corresponding aperture blocked, to form rational cool cycles waterway channel.The sealing property in cooling water channel aperture directly influences the ordinary production of mould use and injection moulding.The sealing in mold cools down water channel aperture at present adopts on soket head cap screw without a head twines certain tetrafluoroethene plastic band to be tightened on the screwed hole that cooling water channel need seal mostly, this sealing means is with low cost, simple to operate, but after after a while, seep water easily, especially easier having water leakage when the pressure of water channel surpasses certain value.Another kind of way is exactly directly to adopt unwanted aperture the mode of welding to seal this way complicated operation, and the change difficulty of water channel.
Summary of the invention
Deficiency at the prior art existence, the purpose of this utility model is to provide a kind of mold cooling system seal plug, it is a composite structure, utilize the different cooling ports that come the sealed mold water channel of the coefficient of expansion of self internal pressure in the water channel and different materials, reaching long service life, good sealing effect and change purpose easily.
In order to realize above purpose, the technical scheme that this practical core adopts is:
The seal plug of mold cooling system, it is by soket head cap screw without a head, copper pipe, pull bar, caulking gum, pull bar connect soket head cap screw without a head and caulking gum, it is characterized in that: add copper pipe between soket head cap screw without a head and caulking gum, total becomes yi word pattern.
Above-mentioned pull bar is the 45# steel.
Above-mentioned caulking gum is a polytetrafluoroethylene (PTFE).
The utility model, the coefficient of expansion that utilizes copper are the twice characteristics of steel, solve the phenomenon that mold temperature raises and causes seal plug to become flexible naturally.The caulking gum seal section is designed to " recessed " font, utilizes self pressure in the mould pipeline to make caulking gum be subjected to side force, make it produce radially enlarged trend, make sealing effectiveness more reliable with this.Pull bar passes copper pipe and connects interior hexagonal without a head and caulking gum, when needs are changed, turns the screw caulking gum and also and then takes closed conduit out of, makes installation and removal very convenient
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an assembling schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, this injection mold cooling system seal plug is by soket head cap screw 1 without a head, copper pipe 2, and pull bar 3, caulking gum 4 is formed, and pull bar passes copper pipe and connects soket head cap screw without a head and caulking gum, and they constitute yi word pattern.Soket head cap screw 1 without a head makes seal plug can be contained in the end of mold cools down pipeline easily.The coefficient of expansion that utilizes copper is the twice of steel, at injection mold cooling system seal plug, the centre adds the copper pipe 2 of certain-length, and copper tube design becomes the diameter that equals closed conduit near the diameter of an end of screw, one end diameter of close caulking gum 4 is less than the closed conduit diameter, when mold temperature raises, the expansion of length and radial direction takes place in copper pipe 2, the expansion of length direction remedies the variation of mold temperature rising size and compresses sealing ring, be radially expanded and make cooperating of the big end of copper pipe and closed conduit become the expansion that interference fit guarantees copper pipe length by excessive cooperation to act on caulking gum 4 fully, this scheme solves the phenomenon that mold temperature raises and causes seal plug to become flexible naturally.Caulking gum 4 is designed to " recessed " font, just can utilizes self pressure in the mould pipeline to make caulking gum be subjected to side force, have radially enlarged trend, make sealing effectiveness more reliable with this.Pull bar 3 passes copper pipe 2 and connects soket head cap screw 1 without a head and caulking gum 4, when needs are changed, turns the screw caulking gum and also and then takes closed conduit out of, makes installation and removal very convenient.
As shown in Figure 2, boring cooling water channel on the template 5, adding the utility model seal plug in the place of needs sealing again, and on template, add quick water swivel.Just can guarantee that cooling water enters from quick water swivel 6, come out, form circulation waterway from quick water swivel 7.
