Abstract

It the utility model is related to a kind of blow moulding table top mould, including left half module and right half module, and it is arranged at the boss on both outer rings, exhaust passage and air cavity are formed during matched moulds between boss, the gas discharged by matched moulds enters aerogenesis pressure after air cavity, gases at high pressure in air cavity inwardly produce gas impulsive force, so that the corresponding position of table produces the reinforcing rib structure to inner process, the blow moulding table top for improving traditional moulds production is vented the shortcomings that hole site wall thickness is thin, so that the intensity of table greatly improves, increase the service life simultaneously；The utility model sets certain cavity by left and right half module periphery exhaust position, promotes the gas of discharge to be fed back through cavity, produces gas impact from outside to inside and forms certain reinforcing rib structure；Product quality, simple in construction, reliable in quality are influenceed so as to solve the problems, such as that matched moulds interface wall thickness is thin.

Description

A kind of blow moulding table top mould

Technical field

It the utility model is related to blow mold, more particularly to a kind of blow moulding table top mould.

Background technology

A few days ago, blow mold outer ring exhaust position used is set for plane in the prior art, the finished product table produced As shown in Figure 1, 2：The position 81 ' of the left half module in periphery and right half module interface, because left and right half module is during matched moulds, it incite somebody to action both Between air carry out it is outer arrange, while there is air pressure in the inner space of tubular blowing raw material, the position 81 ' of matched moulds interface produce to Outer pressure so that the position 81 ' of the matched moulds interface of table protrusion 8 ' is outwardly protruding, so as to cause interface wall thickness thin, Table intensity decreases, influence product quality.

Utility model content

The purpose of this utility model is to provide a kind of blow moulding table top mould, passes through left and right half module periphery exhaust position Certain cavity is set, promotes the gas of discharge to be fed back through cavity, gas impact from outside to inside is produced and forms certain add Strengthening tendons structure；Product quality is influenceed so as to solve the problems, such as that matched moulds interface wall thickness is thin.

To achieve the above object, the utility model provides following technical scheme：

A kind of blow moulding table top mould, it is characterised in that including：

Left half module, the left half module are included located at boss a, the boss b of its outer ring and positioned at groove a between the two, institute Boss a and boss b is stated to set gradually from outside to inside；And right half module, the right half module include be arranged at its outer ring boss c, Boss d and set gradually from outside to inside with boss d positioned at groove b between the two, boss c.

As an improvement, the left half module is engaged with left half module, and product is formed between matched moulds rear left half module and right half module Molding space.

As an improvement, multiple projections are distributed with inside the left half module, the top of the projection and the inside of the right half module Distance is identical with the wall thickness dimension of blowing material used between bottom surface.

As an improvement, when the left half module is in released state with right half module, material flow is formed between the two and leads to space.

As an improvement, the boss a is correspondingly arranged with the boss c, and first exhaust passage is formed between the two；Boss B is correspondingly arranged with boss d, forms second exhaust passage between the two；Groove a is correspondingly arranged with groove b, forms gas between the two Chamber.

As an improvement, the volume of the first exhaust passage is more than the volume of the second exhaust passage, and described first The volume sum of exhaust passage and the second exhaust passage is less than the volume of the air cavity.

The beneficial effects of the utility model are：

The utility model on left half module and right half module by being respectively arranged with boss, with reference to forming first row between boss The characteristics of gas passage, second exhaust passage and air cavity, the air being in during matched moulds between left and right half module is through first exhaust Passage enters air cavity, and original air is more than air cavity volume with entering the air sum of air cavity in air cavity, certain so as to produce Pressure, therefore the gas in air cavity respectively enters first exhaust passage and second exhaust passage, so as to be produced to vent position Raw inside gas impact so that shaping raw material forms reinforcing rib structure, increase the bulk strength of table, enhancing to inner process Its service life.

The utility model has simple in construction, high quality.

Embodiment

Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning Same or similar element is represented to same or similar label eventually or there is the element of same or like function.Below by ginseng The embodiment for examining accompanying drawing description is exemplary, it is intended to for explaining the utility model, and it is not intended that to the utility model Limitation.

As shown in Figure 3,4, a kind of blow moulding table top mould, including：Left half module 1, the left half module 1 are included outside it Boss a11, the boss b12 of circle and set successively from outside to inside positioned at groove a13 between the two, the boss a11 and boss b12 Put；And right half module 2, the right half module 2 include being arranged at boss c21, the boss d22 of its outer ring and recessed positioned between the two Groove b23, boss c21 are set gradually from outside to inside with boss d.

Further, as shown in figure 5, the left half module 1 is engaged with left half module 1, and matched moulds rear left half module 1 and right half module Formed product space 3 is formed between 2.

Further, as shown in figure 5, multiple projections 14 are distributed with inside the left half module 1, the top of the projection 14 and institute Distance is identical with the wall thickness dimension of blowing material used between stating the inner bottom surface of right half module 2.

Further, as shown in fig. 6, when the left half module 1 and right half module 2 are in released state, formation between the two Expect free air space 4.

Further, as shown in figure 5, the boss a11 is correspondingly arranged with the boss c21, and is formed between the two One exhaust passage 5；Boss b12 is correspondingly arranged with boss d22, forms second exhaust passage 6 between the two；Groove a13 and groove B23 is correspondingly arranged, and forms air cavity 7 between the two.

Further, as shown in figure 5, the volume of the first exhaust passage 5 is more than the volume of second exhaust passage 6, and The first exhaust passage 5 and the volume sum of second exhaust passage 6 are less than the volume of the air cavity 7.

It should be noted that as shown in Figure 7,8, be respectively arranged with the outer ring of left half module 1 and right half module 2 boss a11, Boss b12, boss c21 and boss d22, first exhaust passage 5, second exhaust passage 6 and air cavity 7 are formed between boss, is being closed In mold process be in left and right half module between air through first exhaust passage 5 enter air cavity 7, and in air cavity 7 original air with Air sum into air cavity 7 is more than the volume of air cavity 7, is definite value because air cavity 6 holds 7 so as to produce certain pressure, so that Obtain its air pressure inside to increase, caused gas pressure is all higher than the gas pressure passed through in the gentle passage 26 of first exhaust passage 5 Power, and then cause gas during matched moulds in air cavity 7 to be fed into first exhaust passage 5 and second exhaust passage 6 respectively, to first Exhaust passage 5 produces inside gas impact so that is molded on the protrusion 8 of table and inwardly produces projection, strengthens so as to be formed Muscle structure 9.

Pass through mould of the present utility model so that the edge of the table processed forms protrusion 8, and should The reinforcing rib structure 9 to extend internally is formed on the lateral wall of protrusion 8, so that the protrusion of the table processed Intensity is high, and service life greatly prolongs.
