Abstract
The utility model relates to a die of a molded plastic pipe, comprising a concave die (3) and a convex die (8). The concave die is provided with an injection molding hole (14) which is communicated with the inner cavity (4) of the concave die and an exhaust hole (9), and the convex die (8) is provided with a flange disc (1) which is connected with the concave die. The flange disc (1) is tightly clung to the edge position of the inlet end of the concave die, and the flange disc and the edge position of the inlet end of the concave die are connected by a plurality of screw bolts (13). The circumferential surface (10) of the concave die is provided with a plurality of annular convex ribs (11) which are uniformly distributed, and the end surface position of the right end of the inner cavity (4) of the concave die is provided with an annular rabbet which is tightly connected with the circular bead (7) of the convex die (8). The die of a molded plastic pipe of the utility model has simple structure, convenient fabrication, full molding work pieces and good plastic product quality; the die of a molded plastic pipe can process various plastic pipes which are used for discharging town rain water and sewage and comprise structure wall pipes, variable diameter short pipes, etc. The die of a molded plastic pipe can substitute devices and dies which are imported from foreign countries.
Description
Technical field
The utility model is a kind of moulded plastic pipe mold, and it is used to prepare the plastic pipe of cities and towns row's rainwater, sewage.
Background technology
As everyone knows, plastic pipe is a kind of new chemical tubing, have in light weight, corrosion-resistant, inside pipe wall is smooth, conveyance capacity is big, good seal performance, long service life, and is convenient to characteristics such as transportation, installation and speed of application be fast, therefore be used widely at home.At present, the plastic pipe of domestic use is to be produced by expensive overseas equipment of introducing and mould mostly, even the equipment and mold that has part enterprise to adopt foreign imitation to produce is produced, it can not get guaranteeing what do not have to descend yet on price qualitatively.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of moulded plastic pipe mold is provided, it is applicable to the common apparatus of domestic production plastic pipe, and, can produce and the various plastic pipes that comprise structure-wall pipe material etc. of external introducing equipment and mould same performance, the while can reduce cost.
The technical scheme that the utility model adopted is: comprise die and punch, punch is provided with the ring flange that connects die.Ring flange is close to the entrance point edge of die, and they are linked to each other by several bolts.Die is provided with injecting hole and the steam vent that is communicated with its inner chamber.On the side face of die, be provided with some equally distributed ring-type convex tendons.Right-hand member end at the inner chamber of die is provided with the ring-type seam, and the shoulder embedding of itself and punch connects.
Major advantage of the present utility model is: simple in structure, be convenient to make; Can process the various plastic pipes that comprise structure-wall pipe material, reducing short tube etc., to satisfy the market demand of cities and towns discharging rainwater and sewage; Shaping workpiece is plentiful, and the plastic product quality is good; Alternative external introducing equipment and mould reduce cost and promote thereby be beneficial to, and have obvious social and application prospect.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of punch 8 among Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
The utility model is applicable to the common apparatus of domestic production plastic pipe such as fluid pressure type plastic-injection moulding machine for example, its structure as shown in Figure 1 and Figure 2: comprise die 3 and punch 8, punch 8 is provided with the ring flange 1 that connects die 3.Ring flange 1 is close to the entrance point edge of die 3, and they are linked to each other by several bolts 13.Die 3 is provided with injecting hole 14 and the steam vent 9 that is communicated with its inner chamber 4; On the side face 10 of die 3, be provided with the ring-type convex tendon 11 of some equally distributed booster actions; Right-hand member end face 6 places at the inner chamber 4 of die 3 are provided with the ring-type seam, and it closely links to each other with the shoulder 7 of punch 8 (for example embedding connects).
The plastic tube that is used for cities and towns row's rainwater and sewage that processing is bigger for convenience, above-mentioned die 3 can be made up of two or four identical little moulds, concrete structure is: die 3 is formed (see figure 1) by two half identical concave dies, they are divided into two vertically by die 3 and form, and its axial edge 2 that closes up the place is provided with the bolt hole 5 of several connecting bolts.Die 3 also can be made up of four identical little moulds, promptly on the basis of aforementioned per half concave die, it is formed two identical smaller part concave dies again along laterally being divided into two; At the place that closes up of two identical smaller part concave dies, its widthwise edge is along the bolt hole (see figure 1) that is provided with several connecting bolts 12.Therefore, as long as after pulling down bolt, die 3 can decompose, and is convenient to the demoulding, and the plastic tube product of moulding is taken off from punch 8.
Above-mentioned punch 8 is identical with the profile of the plastic tube of cities and towns row's rainwater and sewage.Its structure is as shown in Figure 2: be made up of the ring flange 1 and the die body that combine as a whole.Die body is made up of the bellmouth 16 that is arranged in order, body 17 and tail pipe 18, and is stepped, and they all have tapering.Ring flange 1 combines as a whole with bellmouth 16, and ring flange 1 is provided with several bolts hole 15.The external diameter of the die body of punch 8 is littler than the internal diameter of die 3, and its size can be decided by actual product.
The ring-type seam of above-mentioned die inner chamber 4, its effect is: be positioned at (see figure 1) behind the inner chamber 4 of die 3 when punch 8 die bodys, the one, punch 8 is located in die inner chamber 4; The 2nd, the left side that can make ring flange 1 be close to die 3 is the entrance point edge, and bolt hole 15 back of passing ring flange 1 by several bolts 13 links to each other with die 3 respective threads holes again, thereby punch 8 is fixed; The 3rd, when injection moulding, can prevent that grog from leaking out from the turnover port of die 3.
