Description
Technical field
It is the utility model relates to technical field of mold, in particular to a kind of for being molded the mold of thin-walled tubular plastics.
Background technique
Existing many plastic thin-wall tubes are all to use squeeze technology for forming, but this is all Standard fittings, Er Qieshe
It is standby expensive, many small lot nonstandard products can be encountered in actual production, if using cost price if extruding machine too big,
Injection molding will be generally used, but is that can remain the solution condensation of injection molding in port after being molded first for thin-wall pipe
Object needs to carry out secondary operation cutting, secondly because it is the pipe fitting of thin-walled, during modulus too with the frictional force of mold core
Greatly, it is not easily taken out, is also easy to cause damage of product.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of one-pass molding, facilitates and take out the thin for being molded of product
The mold of wall tubular plastic.
The technical solution of the utility model are as follows:
It is a kind of for being molded the mold of thin-walled tubular plastics, including moulding box and mould column, the moulding box center offers bottom end
Closed die hole opens up a circle overflow launder along die hole open end periphery, and stays between the overflow launder and die hole opening
Truncation surface out, the overflow launder are connected to the edge of moulding box by several diversion trenches；The mould pillar height in the depth of die hole,
Mould top end is connected with traveller, and gland is equipped on the traveller, and the gland bottom end opens up mould identical with mould column cross section
Column slot, and the gland diameter is greater than die throat diameter, the depth of the mould column slot is equal to the depth of die hole and the difference in height of mould column；
Mould column bottom end is connected through a screw thread shape and mentions disk with what die hole matched.
Further, the width of truncation surface is 2-3mm.
Further, overflow launder cross section is trapezoidal.
Further, diversion trench bottom end and the bottom end of overflow launder maintain an equal level.
Further, traveller end is equipped with pull ring.
The utility model has the beneficial effect that
The utility model gland bottom end opens up mould column slot identical with mould column cross section, and the gland diameter is greater than die hole
Diameter, therefore gland can cooperate truncation surface all to squeeze away the extra melt in die hole upper end, guarantee one-pass molding, do not need to cut out
It cuts.Mould column is proposed after condensation, under the action of mentioning disk, finished product will be suggested, and mentioning disk under turning round after proposition can be taken off product.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the quiet mould overlooking structure diagram in Fig. 1.
In figure: 1- moulding box, 11- truncation surface, 12- overflow launder, 13- diversion trench, 14- die hole, 2- mould column, 21- traveller, 22-
Pull ring, 3- mention disk, 4- gland, 41- mould column slot.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
It is as shown in Figs. 1-2:
It is a kind of for being molded the mold of thin-walled tubular plastics, including moulding box 1 and mould column 2,1 center of moulding box offers bottom
Closed die hole 14 is held, opens up a circle overflow launder 12, and the overflow launder 12 and die hole along the 14 open end periphery of die hole
Truncation surface 11 is reserved between 14 open ends, the overflow launder 12 is connected to the edge of moulding box 1 by several diversion trenches 13；It is described
Mould column 2 is higher than the depth of die hole 14, is connected with traveller 21 on 2 top of mould column, gland 4, the pressure are equipped on the traveller 21
4 bottom end of lid opens up mould column slot 41 identical with 2 cross section of mould column, and 4 diameter of the gland is greater than 14 diameter of die hole, the mould column
The depth of slot 41 is equal to the depth of die hole 14 and the difference in height of mould column 2；2 bottom end of mould column has been connected through a screw thread shape and mould
What hole 14 matched mentions disk 3.
First by mould column 2 and mention disk 3 when pouring and be threaded togather, be then placed in moulding box 1, due to mention 3 shape of disk with
Die hole 14 matches, thus between die hole 14 and mould column 2 formed annular pour chamber, then toward annular pour it is intracavitary pour melt,
Until melt overfills die hole 14, the melt for diffusing out die hole 14 can be flowed into overflow launder 12, then flow to recycling by diversion trench 13
Device (not shown) stops pouring at this time, gland 4 be depressed, 4 bottom end of gland opens up mould column slot identical with 2 cross section of mould column
41, and 4 diameter of the gland is greater than 14 diameter of die hole, therefore gland 4 can cooperate truncation surface 11 that 14 upper end of die hole is extra
Melt all squeezes away, guarantees one-pass molding, does not need to cut.Mould column 2 is proposed after condensation, under the action of mentioning disk 3, finished product will
It is suggested, and what is received is that power along tube body axial direction will not damage tube body along with the clamping of die hole 14 and mould column 2.After proposition
Disk 3 is mentioned under torsion can be taken off product.
Specifically, in order not to generate biggish adhesive surface, the width of truncation surface 11 is 2-3mm.
Specifically, the remaining melt of later period cleaning, 12 cross section of overflow launder are trapezoidal for convenience.
Specifically, in order to which the melt in overflow launder 12 can be transported away as far as possible, the bottom of diversion trench 13 bottom end and overflow launder 12
It supports flat.
Specifically, taking out mould column 2 for convenience, 21 end of traveller is equipped with pull ring 22.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
