Description
Technical field
The utility model relates to a kind of anti-clogging RTM mold.
Background technology
RTM is the abbreviation of resin transfer moulding (ResinTransferMoulding).Due to RTM technique, to have production efficiency high, and the accuracy of manufacture is high, and surface quality is good, and can the feature such as complicated goods compared with shape of straight forming, obtains applying more and more widely in the field such as Aero-Space, track traffic.
In RTM mold, core is owing to being in the near closed hollow ring between patrix and counterdie, and die cavity can be full of resin after injecting glue, and resin can block stripper bolt hole, and the demoulding of core must rely on stripper bolt hole.For protection stripper bolt hole, prevent in resin access aperture, blocking demoulding bolt hole of must adopting an effective measure.Because resin has certain viscosity, be difficult to dismantle after tamper and resin bonding in hole and clear up difficulty, and removal force is excessive sometimes, the screw thread in stripper bolt hole is fragile.
Utility model content
The purpose of this utility model be to provide a kind of anti-clogging RTM mold solve in prior art exist there is certain viscosity due to resin, be difficult to dismantle after tamper and resin bonding in hole and clear up difficulty, and removal force is excessive sometimes, the problem such as the screw thread in stripper bolt hole is fragile.
Technical solution of the present utility model is:
A kind of anti-clogging RTM mold, comprise patrix, counterdie and core, upper film and counterdie are formed with enclosed type chamber, core is located in described chamber, enclosed type chamber is provided with gum-injecting port, core is provided with some demoulding bolts hole, anti-bolt hole blocking type bolt is provided with in demoulding bolt hole, anti-bolt hole blocking type bolt comprises bolt head and bolt shank, bolt head is located at the stripping surface of core, bolt head is located at the end of bolt shank, the diameter 20-40mm larger than screw diameter of bolt head, bolt head and bolt shank all adopt polytetrafluoroethylene (PTFE) to make, bolt head is provided with yi word pattern groove, bolt shank is provided with external screw thread, demoulding bolt hole is provided with the internal thread with external screw thread adaptation.
Further, counterdie adopts and establishes reeded square structure, and patrix adopts plate shape, and core comprises some central layers being arranged in order setting, and the notch both sides of counterdie are located at the two ends of central layer respectively.
Further, the two ends of each central layer are respectively equipped with demoulding bolt hole, are equipped with anti-bolt hole blocking type bolt in demoulding bolt hole.
Further, the notch place of described counterdie be provided with for patrix cover along plate, patrix edge and be respectively equipped with some locating holes along plate.
Further, the diameter of bolt head 30mm larger than screw diameter.
Further, the use step of RTM mold comprises:
Paved precast body on counterdie and core, is then assemblied on counterdie by the core with precast body respectively, and close patrix; Mould is moved to baking oven, utilizes the heater of baking oven by after mold heated, by gum-injecting port toward resin by injection in die cavity; After resin solidification completes, patrix is thrown off, utilizes stripper apparatus to deviate from core, thus deviate from composite product.
The beneficial effects of the utility model are: this kind of anti-clogging RTM mold, and structure is simple, do not need cleaning, time saving and energy saving, can enhance productivity.Resin can be effectively stoped to enter the stripper bolt hole of core, and bolt non-stick resin, therefore without the need to clearing up stripper bolt hole and bolt.By the assembling of the rectangular channel of screwdriver insertion head and this bolt can be dismantled.

Detailed description of the invention
Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Embodiment
A kind of anti-clogging RTM mold, comprise patrix 1, counterdie 2 and core, upper film and counterdie 2 are formed with enclosed type chamber, core is located in chamber, enclosed type chamber is provided with gum-injecting port, core is provided with some demoulding bolts hole 4, anti-bolt hole blocking type bolt 5 is provided with in demoulding bolt hole 4, anti-bolt hole blocking type bolt 5 comprises bolt head and bolt shank, bolt head is located at the stripping surface of core, bolt head is located at the end of bolt shank, the diameter 20-40mm larger than screw diameter of bolt head, preferred 30mm, bolt head and bolt shank all adopt polytetrafluoroethylene (PTFE) to make, bolt head is provided with yi word pattern groove, bolt shank is provided with external screw thread, demoulding bolt hole 4 is provided with the internal thread with external screw thread adaptation.
Counterdie 2 adopts and establishes reeded square structure, and patrix 1 adopts plate shape, and core comprises some central layers 3 being arranged in order setting, and the notch both sides of counterdie 2 are located at the two ends of central layer 3 respectively.The two ends of each central layer 3 are respectively equipped with demoulding bolt hole 4, are equipped with anti-bolt hole blocking type bolt 5 in demoulding bolt hole 4.The notch place of counterdie 2 be provided with for patrix 1 cover along plate, patrix 1 edge and be respectively equipped with some locating holes along plate.
This mould structure is simple, does not need cleaning, time saving and energy saving, can enhance productivity.Anti-demoulding bolt hole 4 blocks bolt and adopts polytetrafluoroethylene (PTFE) material, and polytetrafluoroethylene (PTFE) and resin contact have not viscosity, and anti-demoulding bolt hole 4 blocks bolt and can be screwed out easily; And polytetrafluoroethylene (PTFE) can be high temperature resistant, can not be destroyed at injecting glue temperature, safe and reliable.It is large that anti-demoulding bolt hole 4 blocks bolt head diameter, increases the contact area with core, can effectively stop resin to enter demoulding bolt hole 4.The head that anti-demoulding bolt hole 4 blocks bolt has yi word pattern groove, can by the straight screwdriver insertion groove that matches with it, swivel bolt with convenient for assembly with dismounting.It is identical with steel stripper bolt diameter that anti-demoulding bolt hole 4 blocks bolt screw diameter, is convenient to change Steel Bolt and carries out the demoulding.
The use step of RTM mold comprises:
Paved precast body on counterdie 2 and core, is then assemblied in the core with precast body on counterdie 2 respectively, and close patrix 1; Mould is moved to baking oven, utilizes the heater of baking oven by after mold heated, by gum-injecting port toward resin by injection in die cavity; After resin solidification completes, patrix 1 is thrown off, utilize stripper apparatus to deviate from core, thus deviate from composite product.
Before matched moulds, first anti-bolt hole blocking type bolt 5 is screwed in the demoulding bolt hole 4 of core, then the patrix 1 that closes.During the demoulding, patrix 1 is thrown off, insert with yi word pattern screw driver in the yi word pattern groove of anti-bolt hole blocking type bolt 5, anti-bolt hole blocking type bolt 5 is screwed out.Anti-bolt hole blocking type bolt 5 is screwed in stripper bolt hole, knockout press is applied to bolt head, deviates from core.
In embodiment, bolt material is polytetrafluoroethylene (PTFE), is positioned on the stripping surface of core, and core is filled in the enclosure space between patrix 1 and counterdie 2, forms enclosure space after patrix 1 and the 2-in-1 mould of counterdie.Example structure is simple, easy to operate, solves RTM mold at injecting glue process core mould demoulding bolt hole 4 by the problem of the difficult cleaning of resin blocking, time saving and energy saving, improves production efficiency.
