Specific embodiment

The utility model is more fully retouched below with reference to relevant drawings for the ease of understanding the utility model, It states.The preferred embodiment of the utility model is given in attached drawing.But the utility model can come in many different forms in fact It is existing, however it is not limited to embodiment described herein.On the contrary, purpose of providing these embodiments is makes public affairs to the utility model It is more thorough and comprehensive to open content.

It should be noted that when element be considered as " setting " or " connection " on the other element, it can be directly Setting connects on the other element or may be simultaneously present centering elements.

Unless otherwise defined, the technical field of all technical and scientific term and the utility model used herein The normally understood meaning of technical staff it is identical.Term used in the description is intended merely to describe specifically to implement purpose, It is not intended to limit the utility model.

As shown in Figure 1, the mold is made of metal material, including die holder 1, it is provided with the forming cavity 1- at 1 middle part of die holder 1, the side template 2 of two sides in forming cavity 1-1 is arranged in the lower die 4 being placed on inside forming cavity 1-1, and is covered on above die holder 1 Upper mold 3.Wherein: the bottom surface four sides of the top surface of the lower die 4, the corresponding surface of two side templates 2 and upper mold 3 is surrounded to be formed and be formed The consistent filler die cavity of 5 size of product afterwards, is shown in Fig. 2,3.

Specifically, as shown in Figure 1, being provided with limiting stand 1-2 on the die holder 1 of the two sides forming cavity 1-1.The side template 2 is inserted In forming cavity and it is close to setting on the inside of limiting stand 1-2.And the top surface of the side template 2 and limiting stand 1-2 are and form The consistent shape in 5 top surface of product afterwards.Detent is more acurrate when side template can be made to surround filler die cavity by the way that limiting stand is arranged, and is also conducive to The stress intensity of side when increasing binder, while can also play a supporting role to when covering upper mold.

Specifically, as shown in Figure 1, being provided with pumping slot 1-3 and setting on the die holder 1 at the both ends forming cavity 1-1 in pumping slot Two seal groove 1-4 of the medial and lateral 1-3.It is wherein provided with the aspirating hole 1-5 of connection vacuum pump in the pumping slot 1-3, is detailed in Fig. 2.Filled with silica gel sealing material in the seal groove 1-4 (figure does not regard).By setting pumping slot and seal groove, make on die holder It forms one and vacuumizes slot formation sealing vacuum belt, the seal groove filled with silica gel forms a plurality of silica gel protrusion band, taking out During the entire process of vacuum, the micro-strain that energy effective compensation mold occurs in pressured state, the centre of silica gel protrusion in two sides With the vacuum belt compressed is formed, sealing function can be played well, provide preferably molding environment for product.

Specifically, as shown in Figure 1, 2, lower die 4 is placed in forming cavity 1-1.And the front and back ends of lower die 4 are provided with and take, put Handle 4-1.By be arranged handle design more easily lower die can be taken, put out of die holder forming cavity, pass through by Row demoulding again after lower die and shaped article propose completely is more convenient, quick.

Specifically, as shown in Fig. 2, the contact surface of lower die 4 and forming cavity 1-1 are arranged to, top bore is big, bottom bore is small Inclined-plane, taking, putting for lower die can be more conducive to using inclined-plane.

Specifically, setting knob, which can be convenient, to be taken, put and adjusts as shown in Figure 1, the top of upper mold 3 is provided with knob 3-1 The position of upper mold.

Specifically, the corresponding surface of the lower die 4 for being encircled into filler die cavity, side template 2 and upper mold 3 is equipped with not snearing Layer (coating is relatively thin, and figure does not regard).Such as any material that can prevent glass-reinforced plastic material adhesion such as ceramic coating, teflon coatings Material, which applies, to be carried out.Die cavity applies antistick layer, is also more conducive to demould.

When production, die size must be designed according to product requirement.Die cavity need to apply antistick layer, so that mold smoothly exits. Mold shape size directly determines that shape of product and size, each part size must be accurate.Mould structure is shown in attached drawing 1, main It to be made of die holder 1, side template 2, upper mold 3, lower die 4.1 top surface profile of die holder is consistent with the upper surface of product 5, and middle position is opened There is the forming cavity of recess, puts lower die 4 and two pieces of side templates 2 into forming cavity among die holder 1 together, just block, Wu Faqian Positioning is realized in left and right afterwards.Fibre glass product manufacture cross-arm ruler is conformed exactly to by the space that die holder 1, two piece of side template 2, lower die 4 are encircled a city Very little, then the precompressed prepreg in die cavity closes upper mold 3, whole after being vacuumized by vacuum suction mouth to move into curing oven.Gu After change, open upper mold 3, by handle 4-1 by lower die 4, two pieces of side templates 2, products 5 together from forming cavity out, demoulding obtains To qualified products 5.

Embodiment described in the utility model is only the description carried out to preferred embodiments of the present invention, not The utility model conception and scope is defined, under the premise of not departing from the design concept of the utility model, work in this field The all variations and modifications that journey technical staff makes the technical solution of the utility model should all fall into the protection of the utility model Range, technical content requested for protection of the utility model are all described in the claims.
