Further, the outside of described slide block is provided with the voussoir being fixed on front template.
Further, described bottom plate is provided through the guide pillar of top board.
Further, described ventilative bloom is cylindric.
The invention has the beneficial effects as follows: mold insert in the present invention and bushing between form gas-permeable channels, mold insert is provided with horizontal air-vent, mold insert be arranged over ventilative bloom, ventilative bloom is provided with longitudinal air-vent, thus gas can by mold insert and bushing between gas-permeable channels, the horizontal air-vent on mold insert and the longitudinal air-vent on ventilative bloom enter die cavity, it is achieved the air permeable effect of die cavity, solve the vacuum problem formed in die cavity, avoid deformation of products, it is ensured that the quality of product.For mould cooling aspect, cooling water is entered by water inlet water route, then flows longitudinally forward from the left chamber of mold insert, flow into the right chamber of mold insert again, and flow longitudinally rearward, finally flow out through water outlet water route, thus the flow direction cooling down water forms the type of flow of a kind of fountain type, cool down more uniform, ensure that the cooling effect of die cavity, can effectively control mold temperature, it is ensured that product quality, shorten molding cycle, cost-effective.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
nullAs shown in Figure 1,One is breathed freely and the preferable mould of cooling effect,This mould has front mould and rear mold,Front mould includes panel 1 and front template 2,Rear mold includes bottom plate 3、The mould pin 4 being arranged on bottom plate 3 and the rear pattern plate 5 being arranged on mould pin 4,Bottom plate 3 be arranged over top board 6,Described rear pattern plate 5 is provided with slide block 7,Oblique in slide block 7 it is equipped with Angle Pin 8,Front template 2 is provided with front cavity 9,Rear pattern plate 5 is provided with rear cavity 10,Front cavity 9、Die cavity is formed between rear cavity 10 and slide block 7,Bottom plate 3 is provided with into water water route 11 and water outlet water route 12,It is provided with a water route column piece 13 penetrating forward top board 6 and rear pattern plate 5 between water inlet water route 11 and water outlet water route 12,It is arranged with mold insert 14 outside described water route column piece 13,Mold insert 14 has cavity,The cavity of mold insert 14 is divided into left chamber 141 and right chamber 142 by water route column piece 13,The left chamber 141 of mold insert 14 is connected with water inlet water route 11,The right chamber 142 of mold insert 14 is connected with water outlet water route 12,Described mold insert 14 is outer is arranged with again bushing 15,Described mold insert 14 be arranged over ventilative bloom 16,Gas-permeable channels is formed between outer wall and the inwall of bushing 15 of described mold insert 14,Described mold insert 14 is provided with the horizontal air-vent 143 being connected with gas-permeable channels,Described ventilative bloom 16 is provided with the longitudinal air-vent 161 connected with horizontal air-vent 143,Longitudinal air-vent 161 of ventilative bloom 16 communicates with die cavity.
