Description
Technical field
It the utility model is related to high-pressure resin transfer modling technical field, and in particular to high-pressure resin Transfer molding mould
Tool.
Background technology
High-pressure resin Transfer molding mould is a kind of instrument for producing continuous fiber reinforced plastic；Also the company of being to confer to
The instrument of continuous fibre reinforced plastics complete structure and accurate dimension.High-pressure resin transfer modling（HP-RTM）It is that batch production is some
A kind of processing method used during complex-shaped component, is specifically vented, high-pressure injection using preformed member, punching block, vacuum aided
With the dipping and curing process that high-performance thermosetting composite material is completed under high pressure, inexpensive, the short cycle is realized（In high volume）, it is high
Quality produces.
The mould of HP-RTM generally comprises an injection hole, enters resin material by injection hole, and if molding product
Shape is more complicated, then same with thermosetting compound material can not be evenly distributed in whole cavity body of mould by an injection hole, because
This influences the quality of final products, the problem of causing the qualification rate of finished product low.
In view of above-mentioned existing high-pressure resin transfer modling mould there are the defects of, the present inventor be based on be engaged in such production
Product manufacture and design abundant for many years practical experience and professional knowledge, and coordinate the utilization of scientific principle, are actively subject to research and innovation, to
A kind of high-pressure resin Transfer molding mould is founded, it is had more practicality.By constantly research, design, and through anti-
After retrial is made sample and improved, the utility model having practical value is created finally.
Utility model content
The main purpose of the utility model is that overcome existing high-pressure resin transfer modling mould there are the defects of, and
A kind of high-pressure resin Transfer molding mould is provided, the uniformity of product is improved, further improves product qualification rate, so that more
Add suitable for practicality, and with the utility value in industry.
The purpose of this utility model and its technical problem is solved using following technical scheme to realize.
High-pressure resin Transfer molding mould, including upper die and lower die and the injection hole that is arranged in the upper mold, its
In,
The injection hole is one, is arranged in the upper mold；
Multiple diversion trenches are provided with the lower die, are evenly distributed in the cavity of the lower die, for making high-pressure resin
Material is evenly distributed in the cavity that the upper mold and the lower die are formed；
The injection hole is connected with the diversion trench respectively.
Further, the lower die is to be internally provided with the mould of square cavity, and the cavity is internally provided with protrusion
Block, the casting lug thereon is parallel with the upper surface of the lower die, and the diversion trench is arranged on the casting lug thereon.
Further, water conservancy diversion center is provided with the casting lug thereon, respectively with multiple diversion trenches and the injection hole
Connection.
Further, the water conservancy diversion center is circle.
Further, the casting lug thereon is square, and the diversion trench is four, respectively with the square casting lug thereon
Four sides are vertically arranged.
Further, four grooves when being respectively arranged with of the square casting lug thereon, one side of the side groove with it is described
Cavity connects, and the side groove is connected with the corresponding diversion trench.
Further, the width of the side groove is 10-15mm.
Using above-mentioned technical proposal, following technique effect can be realized：
The resin material of one injection hole is drained into cavity body of mould using multiple diversion trenches so that resin material can
It is uniformly distributed, so as to improve the qualification rate of product.
Brief description of the drawings
Fig. 1 is the structure diagram of upper mold in the utility model；
Wherein, 1- upper molds, 2- water conservancy diversion center, 3- diversion trenches, 4- sides groove, 5- cavities.
Embodiment
Further to illustrate that the utility model is to reach the technological means and effect that predetermined purpose of utility model taken,
To according to the utility model proposes high-pressure resin Transfer molding mould its embodiment, feature and its effect, in detail
Describe in detail bright as after.
As shown in Figure 1, the utility model discloses a kind of high-pressure resin Transfer molding mould, including upper mold 1, lower die
With the injection hole being arranged in upper mold 1, wherein,
Injection hole is one, is arranged in upper mold 1；
Multiple diversion trenches 3 are provided with lower die, are evenly distributed in the cavity 5 of lower die, for making resin material uniformly divide
Cloth is in the cavity that upper mold 1 and lower die are formed；
Injection hole is connected with diversion trench 3 respectively, and diversion trench 3 drains the resin material for entering inside cavity by injection hole
Various pieces in cavity so that resin material can be uniformly distributed in inside cavity.
Further, lower die is to be internally provided with the mould of square cavity 5, and cavity 5 is internally provided with casting lug thereon, protrusion
Block is parallel with the upper surface of lower die, and diversion trench 3 is arranged on casting lug thereon.
Further, water conservancy diversion center 2 is provided with casting lug thereon, is connected respectively with multiple diversion trenches 3 and injection hole.Resinous wood
Material enters water conservancy diversion center 2 by the injection hole of upper mold 1, enters again through each diversion trench 3 in cavity from water conservancy diversion center 2.
Further, water conservancy diversion center 2 is circle, and circular water conservancy diversion center 2 will not be detained resin due to no corner angle
Material, so as to save resin material.
Further, casting lug thereon is square, and diversion trench 3 is four, vertical with four sides of square casting lug thereon respectively
Set.
Further, the groove 4 when being respectively arranged with of four of square casting lug thereon, one side of side groove 4 are connected with cavity 5,
