In figure: pedestal 1, forming surface 3, frame structure 4, puts forth effort component 5, hanging ring 6, universal wheel at nose shell molding mould body 2 7, frame upper section 41, frame lower section 42, upper section shape keep circle 43, upper section intensity reinforcing rod 44, lower section shape keep circle 45, under Duan Qiangdu reinforcing rod 46, anti-twisting bar 47.

Specific embodiment

The utility model is described in more detail with reference to the accompanying drawings and detailed description.

As shown in Figure 1, enhancing thin wall-type nose shell shaping mould in a kind of frame structure, including the machine being arranged on pedestal 1 Head-shield forms mould body 2, and forming surface 3 is affixed on the outer surface of nose shell molding mould body 2, the nose shell molding mould body 2 Wall thickness is 15-25mm, further includes in nose shell molding mould body 2 for enhancing nose shell molding 2 intensity of mould body Frame structure 4, the frame structure 4 and the inner surface of nose shell molding mould body 2 fit.

The utility model, in use, by the nose shell molding installation to pedestal 1 of mould body 2, since nose shell forms calligraphy or painting model The wall thickness of body 2 is only 15-25mm, much smaller than the thickness of 35-45mm in the prior art, therefore has more excellent thermal conductivity, Ji Keti Cooling and heating rate in high use process, improve production efficiency, will lead to whole strength reduction since thickness is thinning, Therefore be fitted with frame structure 4 in inside, with enhance nose shell molding mould body 2 integral strength, prevent its repeatedly heating with It is deformed in temperature-fall period, to ensure that product quality.

As shown in Figure 1, the frame structure 4 includes the frame upper section 41 and frame lower section 42 being fixedly connected, the frame Lower section 42 is hollow cylindrical body, and the frame upper section 41 is hollow round table structure, and the cross-sectional area of frame upper section 41 is by leaning on One end of nearly frame lower section 42 gradually becomes smaller to the other end, and such frame structure 4 is whole low wide and up narrow in one kind, gradually tapers up Structure can preferably fit with nose shell molding 2 medial surface of mould body in this way, thus the preferably work of Developed fiber strength enhancing With.

Specifically, the frame upper section 41 includes that several oval upper section shapes keep circle 43, the upper section Shape keeps 43 parts of circle to be embedded in nose shell molding mould body 2, can prevent upper section shape from keeping circle 43 in vertical side in this way It is subjected to displacement upwards, several upper section intensity reinforcing rods 44 are sequentially connected upper section shape and keep circle 43, and such upper section intensity is reinforced Bar 44 and upper section shape keep circle 43 to interweave and form a three-dimensional enhancing grid, and the frame lower section 42 includes several in ellipse Circular lower section shape keeps circle 45, and the lower section shape keeps 45 parts of circle to be embedded in nose shell molding mould body 2, several Root lower section intensity reinforcing rod 46 is sequentially connected lower section shape and keeps circle 45, and the lower section intensity reinforcing rod 46 is reinforced with upper section intensity Bar 44 corresponds, and is fixedly connected, in addition to lower section shape keeps the size of circle 45 all the same and frame in the structure of frame lower section 42 Upper section shape keeps the size of circle 43 to be gradually reduced upwards outside not identical along the vertical direction in the structure of frame upper section 41, remaining structure It corresponds to identical.

Preferably, the upper section intensity reinforcing rod 44 and lower section intensity reinforcing rod 46 are along nose shell molding mould body 2 Axial line is circumferentially uniformly distributed, and two neighboring upper section shape keeps the distance between circle 43 equal, and two neighboring lower section shape is protected It holds that circle the distance between 45 is also equal, can guarantee that the reinforcement power to nose shell molding mould body 2 is evenly distributed in this way.

It preferably, further include anti-twisting bar 47, the both ends of the anti-twisting bar 47 are connected separately with the upper section being not connected with Intensity reinforcing rod 44 and lower section intensity reinforcing rod 46, i.e. two disjunct upper section intensity reinforcing rods 44 and lower section intensity reinforcing rod Anti-twisting bar 47 is equipped between 46, the whole torsional of frame structure 4 can be improved in anti-twisting bar 47, thus prevent nose shell at Pattern ontology 2 is distorted deformation.

In conjunction with shown in Fig. 2 and Fig. 3, the upper surface of the pedestal 1 is fixedly installed several and puts forth effort component 5, using Power component 5 applies a power straight up to pedestal 1, realizes the carrying transfer of pedestal 1, putting forth effort component 5 can be by several Hanging ring 6 forms.

Preferably, described to put forth effort to be located at four vertex of rectangle, and the rectangle diagonal line there are four component 5 sets altogether Angle α be 80-90 degree, in this way in carrying transfer process, pedestal 1 can be made more preferable the power straight up that pedestal 1 applies Holding balance and stability.

In conjunction with shown in Fig. 2 and Fig. 3, the lower surface of the pedestal 1 is fixedly connected with several universal wheels 7, the universal wheel 7 It is corresponded positioned at the underface for putting forth effort component 5, and with component 5 is puted forth effort, is equipped with universal wheel 7 in 1 lower surface of pedestal, can facilitate Pedestal 1 and nose shell molding mould body 2 are shifted.
