Fig. 2 is a partially enlarged schematic view of a portion a in fig. 1.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1-2, the present embodiment provides a double-pitched roof mold, which includes: the device comprises an upper template 1, a lower template 2, an inclined top 3 and a top column 4.
The upper template 1 and the lower template 2 are arranged oppositely from top to bottom.
Two inclined grooves 2a penetrating through the upper end face and the lower end face of the lower template 2 are formed in the lower template 2, and the distance between the two inclined grooves 2a is gradually increased from top to bottom.
The oblique top 3 is two, two 3 one-to-one on the oblique top with two the inclination, the direction of chute 2a are the same, two the upper end one-to-one of oblique top 3 with two chute 2a sliding connection, and two the upper end of oblique top 3 all is provided with barb shaping groove 3a, two barb shaping groove 3a one-to-one arranges in two on the side that the oblique top 3 carried on the back mutually.
The two top pillars 4 are arranged, and the upper ends of the two top pillars 4 are correspondingly abutted against the lower ends of the two inclined roofs 3 one by one; the lower ends of the two pitched roofs 3 are in driving connection with a driving mechanism, and the driving mechanism drives the pitched roofs 3 to move up and down.
Preferably, each of the pillars 4 comprises a roller 41 and a pillar body 42, and the lower end of the pillar body 42 is in driving connection with the driving mechanism; the roller 41 is rotatably connected to the upper end of the prop body 42, and the upper end of the peripheral surface of the roller 41 abuts against the lower end of the lifter 3; in this embodiment, each of the top pillar bodies 42 includes a first connecting pillar 421, a second connecting pillar 422 and a disc spring 423, the lower end of the second connecting pillar 422 is in driving connection with the driving mechanism, and the upper end of the second connecting pillar 422 is provided with a receiving groove formed by a downward recess; the plurality of disc springs 423 are arranged, and the plurality of disc springs 423 are sequentially stacked and arranged in the accommodating groove from top to bottom; the lower end of the first connecting column 421 is slidably disposed in the accommodating groove, and the lower end of the first connecting column 421 abuts against the disc spring 423 at the top, so that the disc spring 423 reduces the instantaneous impact force on the workpiece a in the process of jacking the workpiece a by the lifter 3; the roller 41 is rotatably connected to the upper end of the first connecting column 421.
In this embodiment, the roller 41 is made of a hard alloy material, the outer peripheral surface of the roller 41 is coated with a rubber coating, the lower end of the lifter 3 is fixed with a rubber cushion 3b, the outer peripheral surface of the roller 41 abuts against the lower surface of the rubber cushion 3b, the lower surface of the rubber cushion 3b is provided with anti-slip threads, slipping with the roller 41 is avoided, and meanwhile, the contact stress between the lifter 3 and the roller 41 is reduced.
The working principle is as follows: the two barb forming grooves 3a on the double-pitched roof mould are correspondingly arranged on the opposite side surfaces of the two pitched roofs 3 one by one, after the upper template 1 and the lower template 2 are opened, the driving mechanism drives the two ejection columns 4 to move upwards, the upper ends of the two ejection columns 4 correspondingly drive the two inclined ejectors 3 to slide along the inclined grooves 2a, because the distance between the two chutes 2a is gradually increased from top to bottom, in the process that the two inclined roofs 3 slide along the two chutes 2a, the upper ends of the two inclined roofs 3 are close to each other in the horizontal direction, namely, the two barb grooves 3a are mutually close in the horizontal direction, thereby realizing the demoulding of the barb forming grooves 3a, avoiding the interference in the process of taking out the workpiece a, meanwhile, the two inclined roofs 3 jack the workpiece a upwards, so that the workpiece a is convenient to take down.
