Abstract
The utility model provides a shaping mould for forming a penholder, which comprises an integrated mould head and an integrated mould tail, wherein the longitudinal section of the shaping mould is in a convex shape, and the central axis of the shaping mould is provided with a forming through hole. The shaping mould is characterized in that the shape of the forming through hole is a Y-shaped hopper, the diameter of the inner wall of the forming through hole in the mould head is gradually contracted, and the diameter of the forming through hole in the mould tail is equal. In the utility model, the front end of the forming through hole is made to be trumpet-shaped so as to relatively shorten the equal diameter-shaped forming through hole, therefore, the front end of the forming through hole is beneficial to accepting compounded pencil core material and pencil rod material from a composite mould, and the drawing speed is enhanced; and simultaneously, as the diameter of the inner wall of the forming through hole of the mould head is gradually contacted, the mould is favored for the peripheral distribution of the pencil rod material, the penholder is even in thickness and the pencil is good in quality.
Description
[technical field]
The utility model belongs to a kind of penholder forming and setting mold, relates in particular to a kind of penholder forming and setting mold of Lignified plastic pencil.
[background technology]
The pencil appearance is with a long history, purposes has a large capacity and a wide range, and the history that adopts solid wood to make pencil according to the history record had more than 300 year.Along with the continuous development of science and technology, to make pencil and become trend to mould substitute wood in recent years, and show out bright development prospect especially, manufacture craft also is gradually improved.The patent No. is 011131217 " Lignified plastic pencil and manufacture craft thereof ", discloses a kind of method of producing Lignified plastic pencil.In this method, have a step pen core material, the composite molding of penholder material to enter the stock mould typing after, enter the operation of bosh cooling again.The longitudinal section of stock mould is " protruding " font, has a forming through hole on its axis, and the ring wall shape of forming through hole is set according to the pencil profile, and hexagon, triangle or the like are to obtain the pencil of corresponding profile.During installation, the protuberance level of stock mould is embedded in the feed end of bosh.During operation, be introduced into the forming through hole of stock mould through the pencil shaft material of compound die composite molding, through typing, cool off and cut after make product.
In the said method since the reasons in structure of stock mould there are the following problems so far: draw rate is slow, is wrapped in the penholder became uneven of pen core periphery, and pencil is of poor quality.
[summary of the invention]
For overcoming the prior art above shortcomings, the utility model aims to provide a kind of penholder forming and setting mold, utilizes this stock mould to make Lignified plastic pencil, can effectively improve draw rate, and the pencil holder thickness of making is all even, and the pencil quality is good.
For achieving the above object, the utility model has adopted following technical scheme: this penholder forming and setting mold, comprise all-in-one-piece die head and mould tail, the longitudinal section is " protruding " font, has a forming through hole on the axis, it is characterized in that: the hole shape of described forming through hole is the infundibulate of " Y " shape, and the diameter of the forming through hole in the inner diameter convergent of the forming through hole in the die head, mould tail is isometrical.
During concrete enforcement, the inwall of the forming through hole in the described mould tail is the hexagon ring wall.
During concrete enforcement, the inwall of the forming through hole in the described mould tail is the triangle ring wall.
Beneficial effect: compared with prior art, with the front end of forming through hole make horn-like after, shortened the forming through hole of isometrical shape relatively, thereby both helped the front end of forming through hole, the composite molding pencil shaft material that admittance is come out from compound die improves draw rate; Simultaneously, the die head forming through hole of inner diameter convergent also helps the circumferential distribution of penholder material, thereby it is even to reach the penholder thickness, the measured purpose of pencil matter.Measure through statutory machinery, the uniformity of penholder thickness has obtained increasing substantially.
[description of drawings]
Fig. 1 is the broken section structural representation of an embodiment of the utility model.
Fig. 2 is that the K of Fig. 1 is to structural representation.
Among the figure: die head 1, mould tail 2, tapered wall 3, moulding hole 4, die head ring limit 5.
[specific embodiment]
Referring to Fig. 1, and in conjunction with Fig. 2.The profile of this stock mould is same as the prior art, therefore, its installation method, and also consistent with the coupling of the bosh at the compound die in operation the place ahead, rear, cutting mechanism etc. with prior art, no longer burdensome at this.
Die head 1 and mould tail 2 are monolithic construction, and its longitudinal section is " protruding " font, have a forming through hole on the axis, and the positioning and fixing effect is mainly played on die head ring limit 5.Innovative point of the present utility model is: forming through hole 4 hole shapes of " one " font that will be originally isometrical are designed to be the infundibulate of " Y " shape, make the hole inner diameter convergent on the die head 1, become tapered wall 3.And the diameter that makes mould tail 2 forming through hole 4 keeps original structure, is isometrical shape, plays real styling.
