Description

A kind of box part RTM mold

Technical field

The utility model is related to a kind of box part RTM molds.

Background technology

RTM is also known as resin transfer moulding or Resin Transfer Moulding molding, refers to flowing leaching in Guan Bi mould by low viscosity resin A kind of technology for moistening reinforcing material and curing molding, belongs to the liquid molding process in Composites Molding Techniques；RTM works Skill has good moldability, and the Composite Degrees of Freedom of reinforcing material and matrix resin is wide, and the features such as can improve operating environment, and does not have Have organic solvent and fiber is vaporized problem；The mold closing resin method for implanting of RTM can greatly reduce the harmful components pair of resin The murder by poisoning of human body and environment, therefore, RTM technologies are widely used in the moulding process of composite material.

In RTM mold, it is often used in the product of shaping box Shape closed structure, the packet that such product often can be tightly after curing It is rolled on core, without corresponding impetus, it is difficult to be taken off from core, and usually damages system since this violence demoulds Part scratches article surface, causes waste product.

Invention content

The utility model provides a kind of box part RTM mold, difficulty when existing box part demoulding is solved the problems, such as, using this Default demoulding block demoulding can easily screw out demoulding block from mold, to eject product.

In order to achieve the above object, the utility model is achieved through the following technical solutions：

The utility model is a kind of box part RTM mold, including upper die and lower die, upper die and lower die are respectively equipped with injecting glue Mouthful, upper die and lower die form enclosed type chamber, and pellet is arranged in chamber and demoulds block, and the four of demoulding block insertion box part lower die A edge, and box-shape part, in paving, height spreads to demoulding block and ejects face, the quantity of pellet is four and is trapped among box-like Around part, and pellet has 10 ° of gradients, and tapped through hole is equipped on demoulding block, and when demoulding, bolt screws in tapped through hole, Until bolt bottom surface is contacted with lower die, continue to screw in bolt, demoulding block moves upwards to eject product relative to bolt.

The use step of the RTM mold of the utility model includes：The paved box part precast body on the core of lower die, height Then four pellets are inwardly compressed to the ejection face for demoulding block, close upper mold using guide post and fine theta positioner, in mold four by paving Zhou Xiangying rational positions are locked upper die and lower die with bolt, and mold is moved to baking oven, using the heating device of baking oven by mold After heating, resin is injected in chamber by gum-injecting port；After the completion of waiting for resin solidification, product stripping is carried out, upper mold is disengaged, core Block is dismantled around, and bolt screws in the threaded hole of demoulding block, until bolt bottom surface is contacted with lower die, continues to screw in bolt, demoulding Block moves upwards to eject product relative to bolt.

The utility model has the beneficial effects that：This kind of box part RTM mold is respectively set one at four angles of box part Block is demoulded, and makes product paving to the ejection face for demoulding block, difficulty when demoulding can be substantially reduced, and easy to operate, time saving province Power, when demoulding, using stripper bolt can be easy back-out demoulding block, to take off product from core, simply It is easy to operate.

Wherein：1- upper molds；2- pellets；3- demoulds block；4- lower dies.

Specific implementation mode

In order to deepen the understanding to the utility model, the utility model is done further below in conjunction with drawings and examples Detailed description, the embodiment are only used for explaining the utility model, do not constitute and limit to the scope of protection of the utility model.

As shown in Fig. 1 ~ 4, the utility model is a kind of box part RTM mold, including upper mold 1 and lower die 4, the upper mold 1 It is respectively equipped with gum-injecting port with lower die 4, the upper mold 1, lower die 4 form enclosed type chamber, and pellet 2 is arranged in the chamber and takes off Module 3, demoulding block 3 is embedded in four edges of box part lower die 4, and box-shape part, in paving, height is spread to demoulding block 3 Ejection face ejects product when to demould, that is to say, that four demoulding blocks are respectively arranged at four angles of box part, when demoulding, Four angles act on upward ejecting force respectively, and to make product be taken off from the core of lower die, the quantity of the pellet 2 is four It is a and be trapped among around box part, and pellet 2 has 10 ° of gradients, equipped with tapped through hole on the demoulding block 3, when demoulding, Bolt screws in tapped through hole, until bolt bottom surface is contacted with lower die 4, continues to screw in bolt, demoulding block 3 is transported upwards relative to bolt It moves to eject product.

It is equipped with raised core structure among lower die 4, corresponding demoulding 3 riding position of block is opened up at four angles, and from lower die 4 Bottom surface is emptied inside it, can mitigate mold weight, and convenient for heating, it is made to be heated evenly, upper mold 1 is using identical with lower die 4 Shape reserves corresponding pellet placing position in upper mold 1, when molding, compresses product around using the gradient of pellet 2, demoulds Tapped through hole is opened up on block 3, stripper bolt screwin is deviate from into product to ejection device block 3.

The use step of RTM mold includes：The paved box part precast body on the core of lower die 4, height paving to demoulding block 3 Ejection face, then by four pellets 2 inwardly compress, close upper mold 1 using guide post and fine theta positioner, accordingly closed in mold surrounding Reason position bolt locks upper mold 1 and lower die 4, and mold is moved to baking oven, after mold is heated using the heating device of baking oven, Resin is injected in chamber by gum-injecting port；After the completion of waiting for resin solidification, carry out product stripping, upper mold 1 is disengaged, pellet 2 to Surrounding is dismantled, and bolt screws in the threaded hole of demoulding block 3, until bolt bottom surface is contacted with lower die 4, is continued to screw in bolt, is demoulded block 3 It moves upwards to eject product relative to bolt.
