Abstract
The utility model discloses a plastic irregular section shaping mould device. The utility model is characterized in that the outer side of a mould cavity is provided with an irregular mould sleeve which is arranged in a water tank. The water tank is provided with a through hole, and a wall of the mould sleeve is provided with holes or gaps which are communicated with the mould cavity. The utility model causes a dry type shaping device to be designed into a similar mould cavity-shaped mould sleeve type. Gaps or holes which are communicated with the mould cavity are distributed on the mould sleeve, and the mould sleeve is completely arranged in the vacuum water tank to cause the mould sleeve to be cooled uniformly in a high efficiency way. Simultaneously, the negative pressure in the vacuum water tank causes a plastic parison and a product to be closed to the mould cavity of the mould sleeve to be shaped effectively. Therefore, the severe cooling of a high temperature parison is avoided, the cooling efficiency and the cooling homogeneity are improved, and the efficient and uniform cooling of a plastic product is obtained.
Description
Technical field:
The utility model relates to the cooling shaping apparatus technology of producing in the plastic irregular profile extrusion, specifically a kind of plastic irregular profile setting die device.
Background technology:
In the production process of plastic irregular profile extrusion molding, the thermoplastic materials parison of extruding from head must fully cool off it and formalizes by cooling shaping device, just can become end article (being product), water is its cooling medium, the height of the cooling effectiveness of right cooling shaping device and the uniformity of cooling are the production efficiency of the whole extrusion molding production system of decision plastic irregular profile and the key factor of end article quality, be to weigh the important performance indexes of extruding shaping device, it is to adopt to do that existing advanced plastic irregular profile is extruded the setting method, the system configuration that the wet vacuum shaping device is in series, ask for an interview Fig. 1, in this system configuration, the wet vacuum setting of the dry vacuum setting (being commonly called as stock mould) of forward part and rear section, structurally be two relatively independent devices, and each architectonical of its cooling system and vacuum system, irrelevant mutually, wherein the wet vacuum shaping device also is water-bath type vacuum setting case, it mainly formalizes to the profile shapes goods of cooling and shaping, but this type of cooling process is very violent, be not suitable for the high temperature parison of just the extruding cooling that formalizes from die head, the physics that will cause product deformation and do not reach regulation because if the cooling of high temperature parison too acutely will cause it to produce very big internal stress, mechanical performance index, so just must finalizing the design at wet vacuum, the dry vacuum calibrator is set is stock mould in the front, so-called dry vacuum setting is exactly that cooling water does not directly contact with goods with parison, cool off indirectly, present dry vacuum calibrator is to come die sleeve is cooled off by the method that cooling water channel is set around the die sleeve die cavity, because of water channel can't contain whole die sleeve mold cavity surface (asking for an interview Fig. 2) simultaneously, thereby cooling effectiveness and uniformity are all undesirable.
Summary of the invention:
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of plastic irregular profile setting die device is provided
The technical solution of the utility model is achieved in that a kind of plastic irregular profile setting die device, it mainly comprises die cavity and water tank, it is characterized in that: be provided with the shaped die cover outside die cavity, die sleeve places water tank, be provided with through hole at water tank, be provided with hole or the seam that is connected with die cavity at the die sleeve wall.
It is the thin-walled module that the utility model is designed to the die sleeve form similar to cavity shape with the dry type shaping device, be distributed with the seam or the hole that are connected with die cavity on the die sleeve, and die sleeve placed vacuum water tank fully, make it obtain efficient and cooling uniformly, simultaneously make plastic parison and goods press close to the die sleeve die cavity and effectively formalized by the negative pressure in the vacuum water tank, so both avoided the violent cooling of high temperature parison, improved cooling effectiveness and cooling uniformity again greatly, made plastic products obtain efficient and cooling uniformly.

Fig. 4 is the structural representation of the utility model one embodiment
The specific embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
A kind of plastic irregular profile setting die device, it mainly comprises die cavity 2 and water tank 3, and it is different from prior art and is: be provided with the special-shaped die sleeve 1 similar to die cavity outside die cavity 2, die sleeve 1 places water tank 3, be provided with through hole 5 at water tank 3, be provided with the hole that is connected with die cavity or stitch 4 at the die sleeve wall; Water tank 3 is the water tank of vacuum-pumping in the enforcement, and die sleeve 1 places among the vacuum water tank 3; Wall at die sleeve 1 evenly is provided with the hole that is connected with die cavity 2 or stitches 4.
Dry type shaping device of the present utility model is designed to the form of die sleeve, its die wall is thinner, the utmost point is beneficial to heat conduction, because with its whole vacuum water tank that places, swiftly flowing cooling water medium has contained its whole surface area to the cooling of die sleeve 1 and die cavity 2, rather than only by some narrow water channels, thereby the cooling water flow ratio that acts on die sleeve and die cavity will become the increase of how much multiples by the discharge of having only narrow cooling water channel, cooling effectiveness and intensity of cooling have obtained improving greatly, are suitable for the high speed extrusion molding more; Because die wall is even, thinner, be again whole placing in the middle of the cooling water tank, space around it is equal substantially, cooling water in the water tank is to be in a kind of flow regime successively clocklike, thereby die sleeve 1 and die cavity 2 are among the even containing of cooling water all the time, cooling water is in cross-sectional direction to the cooling of die sleeve 1 and die cavity 2 or the longitudinal section direction is all affacted in order, so just improved the uniformity of die cavity cooling widely, also just improved the uniformity of goods coolings, thereby reduced the internal stress of goods, improved shape of products, dimensional accuracy and physics, mechanical property helps high-speed extrusion molding; Because stock mould of the present utility model is the form that adopts die sleeve, so just reduced the use amount of main material, it is again to place vacuum water tank fully simultaneously, vacuum structure part and cooling structure part in the existing stock mould device have been saved, but these two parts are the unit cost about 50% of direct saving material just, adopted its die length of dry type shaping device of this water-bath die sleeve form can also save more than 1/2nd, but thereby whole dry type shaping device economical with materials cost about 80%, saved the technology and the time cost of Mold Making greatly.
