Abstract
The utility model discloses a water crusting PVC (Polyvinyl Chloride) foamed sheet double-layer runner mold. The water crusting PVC (Polyvinyl Chloride) foamed sheet double-layer runner mold is characterized by comprising an upper mold body, a middle mold body and a lower mold body, wherein a core rod is arranged at the front end of the middle mold body, an upper runner is arranged between the upper mold body and the middle mold body, a lower runner is arranged between the lower mold body and the middle mold body, the upper mold body and the lower mold body are provided with regulating rods, the upper mold body is connected to an upper mold lip, the lower mold body is connected to a lower mold lip, the upper mold lip and the lower mold lip are connected to water cooling blocks, water cooling circulating pipelines are arranged in the water cooling blocks, and heat insulation layers are arranged among the water cooling blocks, the upper mold lip and the lower mold lip. Compared with the prior art, the water crusting PVC (Polyvinyl Chloride) foamed sheet double-layer runner mold has the advantages that the upper runner and the lower runner of the mold take on the shape of a clothes rack in a vertical direction, the feeding is uniform, the product size is accurate, the density of foamed products is relatively uniform, the strength of the products is relatively high, and the water cooling blocks can be used for rapidly cooling melts at a discharge hole so as to form relatively thick crust, so that the products have smooth surfaces and high hardness and are wear-resistant and unlikely to scratch.
Description
Technical field
The utility model relates to a kind of PVC foamed board goods mould, relates in particular to a kind of water skinning PVC foaming plate double-layer channel mould, belongs to mechanical field.
Background technology
Conventional P VC foamed board mould is individual layer runner, and the extrudate density of producing is inhomogeneous, and section intermediate layer density is less, to superficial layer, increases gradually, and surface flatness, hardness is not good enough, wearability a little less than, and intensity also a little less than, not high goods can only meet the demands.
Summary of the invention
The utility model is in order to solve above-mentioned deficiency, and a kind of water skinning PVC foaming plate double-layer channel mould is provided.
Above-mentioned purpose of the present utility model realizes by following technical scheme: a kind of water skinning PVC foaming plate double-layer channel mould, it is characterized in that: comprise upper die body, middle die body and lower mold body, described middle die body front end is provided with plug, between described upper die body and middle die body, be provided with upper runner, between described lower mold body and middle die body, be provided with lower flow channel, in described upper die body and lower mold body, be equipped with regulating rod, described upper die body is connected with die lip, described lower mold body is connected with lower die lip, described upper die lip and lower die lip are all connected with water-cooled block, in described water-cooled block, be provided with Water-cooling circulating pipeline, described water-cooled block and upper die lip, between lower die lip, be provided with thermal insulation layer.
The utility model advantage is compared with prior art: upper and lower double-layer channel of the present utility model is clothes rack shape in vertical direction, uniform feeding, and product size is accurate, and foaming product density is more even, and product strength is higher; Water-cooled block can be cooling and form thicker skinning rapidly by melt at discharging opening, makes product surface smooth, and hardness is high, and wear-resisting difficult scuffing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of water skinning PVC foaming plate double-layer channel mould, it is characterized in that: comprise upper die body 1, middle die body 2 and lower mold body 3, described middle die body 2 front ends are provided with plug 4, between described upper die body 1 and middle die body 2, be provided with upper runner 5, between described lower mold body 3 and middle die body 2, be provided with lower flow channel 6, described upper die body 1 is provided with regulating rod 7, lower mold body 3 is provided with regulating rod 8, described upper die body 1 is connected with die lip 9, described lower mold body 3 is connected with lower die lip 10, described upper die lip 9 is connected with water-cooled block 11, lower die lip 10 is connected with water-cooled block 12, in described water-cooled block 11 and water-cooled block 12, be provided with Water-cooling circulating pipeline 15, between described water-cooled block 11 and upper die lip 9, be provided with thermal insulation layer 13, between described water-cooled block 12 and lower die lip 10, be provided with thermal insulation layer 14.
Finally it should be noted that: above-described embodiment is only for the utility model example is clearly described; and the not restriction to embodiment; for those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description; here exhaustive without also giving all embodiments, and the apparent variation of being amplified out thus or change are still among protection domain of the present utility model.
