Abstract
The utility model discloses a heat of preventing creep plastic seal ring utensil of moulding belongs to sealing member manufacturing technical field, including the mould body, its characterized in that, this internally is equipped with two -layer embedding slot the mould, the last a plurality of fill opening that sets up of embedding slot, each layer embedding slot's top set up the plastic feed inlet, and the below sets up the plastic discharge gate, upper and lower the covering of mould body sets up a plurality of air conditioning holes. The utility model discloses set up a plurality of fill openings, overcome the insufficient problem of foaming polyurethane filler, set up the air conditioning hole simultaneously for heat is moulded, and the utensil is even cools down, improves the qualification rate of product.
Description
Technical field
The utility model relates to pinoplastics moldings field, specifically, is the pinoplastics moldings of anti-creep plastic cement seal washer.
Background technology
Plastic cement all has " cold flow properties ", makes the plastic deformation that plastic cement seal washer occurs under the effect of long-time continuous load, i.e. creep, and this brings certain restriction to its application.Tightly that bolt is very tightly stubborn for sealing, so that when exceeding specific compression stress, packing ring can be made to produce " cold flow " (creep) and be crushed.These shortcomings directly affect sealing property and the service life of seal washer.
Polyurathamc is a kind of special polyurethane products components such as polyurethane Yu Ju Wu ﹑ Fa Pao Ji ﹑ catalyst filled in withstand voltage inhalator jar.When material sprays from inhalator jar, the polyurethane materials of foam shape can undergoes rapid expansion form foam with the moisture generation curing reaction in air or the matrix that touches.Foam after solidification has the multi-effects such as Tian Feng ﹑ Nian Jie ﹑ Mi Feng ﹑ Ge Re ﹑ sound-absorbing, is that a kind of Huan protects Jie Neng ﹑ construction material easy to use.But be also the extremely incendive material of one.
In plastic cement seal washer, filling-foam polyurethane effectively can overcome the creep of plastic cement seal washer, but in the fabrication process, because polyurathamc expansion rate is fast, the filling distance is short, common pinoplastics moldings can cause filling insufficient, causes product percent of pass low; In addition, whether the chilling temperature of thermoplastic product is evenly the key affecting thermoplastic product quality, and common pinoplastics moldings adopts annular cooling channel, easily causes inhomogeneous cooling, and then affects the qualification rate of product.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides the pinoplastics moldings of anti-creep plastic cement seal washer, overcomes creep by the method adding suitable filler.
For achieving the above object, the utility model provides following technical scheme:
The utility model relates to the pinoplastics moldings of anti-creep plastic cement seal washer, comprise die ontology, it is characterized in that, two-layer built-in groove is provided with in described die ontology, described built-in groove is arranged several stuffing holes, the top of every one deck built-in groove arranges plastic cement charging aperture, and below arranges plastic cement discharging opening, and described die ontology upper and lower cover arranges some cold air hole.
Preferably, the aperture of described stuffing hole is 1.5 ~ 2cm.
Preferably, the aperture of described cold air hole is 0.5 ~ 1mm.
Compared with prior art, good effect of the present utility model is:
1. the utility model arranges multiple stuffing hole, overcomes the problem that polyurathamc filler is insufficient, arranges cold air hole simultaneously, makes pinoplastics moldings's uniform decrease in temperature, improves the qualification rate of product.
Accompanying drawing explanation
Fig. 1 is the section of structure of the pinoplastics moldings of anti-creep plastic cement seal washer;
Mark in accompanying drawing 1 is respectively: 1. die ontology; 2. built-in groove; 3. stuffing hole; 4. upper cover; 5. lower cover; 6. plastic cement charging aperture; 7. plastic cement discharging opening; 8. cold air hole.
Detailed description of the invention
The technological means realized to make the utility model, character of innovation, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, the pinoplastics moldings of anti-creep plastic cement seal washer, comprise die ontology 1, it is characterized in that, be provided with two-layer built-in groove 2 in described die ontology 1, described built-in groove arranged several stuffing holes 3, the top of every one deck built-in groove arranges plastic cement charging aperture 6, below arranges plastic cement discharging opening 7, and described die ontology upper and lower cover 4,5 arranges some cold air hole 8.
Preferably, the aperture of described stuffing hole is 1.5 ~ 2cm.
Preferably, the aperture of described cold air hole is 0.5 ~ 1mm.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, therefore all changes be intended in the implication of the equivalency by dropping on claim and scope are included in the utility model, any Reference numeral in claim should be considered as the claim involved by limiting.
