Description

Y shape water tank hollow molding device

Technical field

This utility model relates to a kind of plastic hollow molding device, refers in particular to a kind of Y shape water tank hollow molding dress Put.

Background technology

As it is shown in figure 1, Y shape water tank 1, this product screw becomes Y-shaped and product main body the thinnest, routinely at big plane side Moulding process be difficult to molding, in order to have employed 2 kinds of forming methods before this product: 1) rotational moulding, in this way rotation molding Time is longer, and yield is the lowest, and economic benefit is the highest.2) screw socket is made piece moulding inlaying and is put into molding in hollow die body.According to this side Method screw socket makes piece moulding inlaying, though higher than rotational moulding yield, but to open one pair of screw socket injection mold more, virtually add artificial and Cost, but also want workman with hands, screw socket mold insert to be put in mould in blow-molding process every time, just slip up once operative Can cause danger and industrial accident, company is produced heavy losses not to individual.

Utility model content

This utility model provides a kind of Y shape water tank hollow molding device, its object is to solve conventional molding process difficult With the problem manufacturing Y type water tank.

A kind of Y shape water tank hollow molding device, including the mould backboard being connected with machine backboard, is located on mould backboard Mould, blow needle and encapsulating mechanism, described mould backboard include just to the first mould backboard and the second mould backboard, mould is by phase A mould, B mould and the C mould composition coordinated mutually, wherein A mould is located on the first mould backboard, and B mould and C mould are located on the second mould backboard The side relative with A mould, B mould and C mode division do not control to move out to the second mould backboard both ends horizontal by two side oil pumping cylinders Mould.

Wherein, described blow needle is located between B mould and C mould, and can be along the movement being perpendicular to the second mould backboard direction level.

Wherein, described encapsulating mechanism includes the first encapsulating, the second encapsulating that can be movable relatively, and drives first, second The actuating device of encapsulating action and tracker action, wherein the first encapsulating is located at below A mould, and the second encapsulating is located under B mould and C mould Side, encapsulating opening is left in the position that described first encapsulating is right against blow needle.

Wherein, it is for molding Y shape water tank screwed hole near the side of the second mould backboard after described B mould and C mould Guan Bi Screw socket portion.

This utility model manufactures Y shape water tank, in the mode of three die sinkings makes mold cavity by the way of T-shaped three die sinkings Portion forms larger space, makes material base have enough expansive spaces, preventing material base in die space stenosis adhesion, making in order to avoid affecting Product molding, prevents oral area back-off simultaneously, also allows for die sinking.Carry out blow needle by the mobile setting of blow needle and draw the step of material, blowing Can make to have at screw socket enough material base molding before gas, it is not necessary to separately by injection casting screw socket mold insert.It addition, pass through sealing machine Material base bottom is sealed and carries out air-blowing by structure, enables material base fully to be blown greatly, thus ensures that product wall thickness is uniform, it is simple to goods become Type.Meanwhile, encapsulating mechanism in the middle part of be provided with encapsulating opening, it is simple to avoid blow needle when die trial, convenient operation.This practicality New structure is simple, low cost, by using this utility model to carry out the hollow molding of Y shape water tank, it is possible to be effectively improved manufacture Efficiency, moreover it is possible to ensure the safety produced.

Detailed description of the invention

This utility model is further elaborated by following example:

A kind of Y shape water tank 1 hollow molding device, including the mould backboard being connected with machine backboard, is located on mould backboard Mould, blow needle 7 and encapsulating mechanism, described mould backboard include just to the first mould backboard 2 and the second mould backboard 3.Two Individual mould backboard can be driven by machine and carry out relative motion.Mould is made up of the A mould 4 cooperated, B mould 5 and C mould 6.A mould 4 sets On the first mould backboard 2, B mould 5 is located at side relative with A mould 4 on the second mould backboard 3 with C mould 6, and B mould 5 and C mould 6 closes After conjunction, the side near the second mould backboard 3 is the screw socket portion for molding Y shape water tank 1 screwed hole.Edge on second mould backboard 3 Horizontal direction is provided with the guide rail 8 parallel with backboard, and the two ends of the second mould backboard 3 are respectively installed with by oil cylinder fixed plate 18 One side oil pumping cylinder 9, B mould 5 and C mould 6 is controlled along guide rail 8 to the second mould backboard 3 two ends water by two side oil pumping cylinders 9 respectively The dynamic die sinking of translation.Blow needle draws material cylinder 10 to be coordinated by gear 11 and tooth bar 12 to drive blow needle 7 to the between B mould 5 and C mould 6 Two molds backboard 3 direction is moved and is carried out drawing material.Encapsulating mechanism includes first encapsulating the 13, second encapsulating 14 that can be movable relatively, its In the first encapsulating 13 be located at below A mould 4, encapsulating opening 15 is left in the positions that the first encapsulating 13 is right against blow needle 7, in order in die trial Time avoid blow needle 7.The lower section of B mould 5 and C mould 6 is located in second encapsulating 14.Encapsulating cylinder 16 drives the by rack synchronous mechanism 17 One, the second encapsulating 13,14 carries out move toward one another.

Job step of the present utility model is as follows:

1) T-shaped three die sinkings, during die sinking, make first to open between A mould 4 and B, C mould 6, and then B mould 5 and C mould 6 is pumped in side Along guide rail 8 to both sides die sinking under the effect of cylinder 9, so can make to open inside mold cavity greatly as far as possible, make material embryo have enough exhibitions Opening space, not allowing material embryo stick together in die space stenosis affects product molding, and so typing makes oral area not have Back-off, it is simple to die sinking.

2) blow needle draws material, and to blow needle 7 position under after three die sinkings, material base is at mold center, blow needle draws material cylinder 10 to pass through Gear 11 and tooth bar 12 cooperation drive blow needle 7 move to the second mould backboard 3 direction between B mould 5 and C mould 6 and carry out drawing material.? Can make to have at screw socket enough material embryo formings before air blowing, thus need not put injection screw socket mold insert and suffer to mould.

3) encapsulating air-blowing, before matched moulds is blown, encapsulating cylinder 16 makes the first encapsulating 13 and the by rack synchronous mechanism 17 Two encapsulatings 14 toward mold center's direction motion, material embryo sealed bottom air-blowing, so can make material embryo space blow greatly, system simultaneously as far as possible Product uniform wall thickness, it is simple to the molding of goods.

4) blowing moulding, mould closes, and blow needle 7 starts to blow, and material embryo is in a mold through the most plastic. Formed product rear mold is opened, and is taken off by the product being enclosed within blow needle 7.

Foregoing description has illustrated explanation and the description of utility model.It is not configured to limit this utility model For disclosed form and mode.According to above mode, can revise accordingly or change.It is in order to more that example is discussed Principle of the present utility model and practicality thereof are described well, thus utilize this utility model carry out various amendment and meet other spy Fixed demand.All such modifications and variations are worked as according to fair and legal right deciphering, and according to accessory claim, this A little modifications and variations broadly fall in the range of this utility model.
