Abstract

The utility model provides a lower female die of a plastic bottle cap molding press. A step ring (11) is formed on a lower female die body (10); an upper step (1a) and a lower step (1b) are formed by the step ring (11) and the lower female die body (10); a water flow guide ring (12) provided with an opening (121) is formed at the lower part of the lower step (1b); a die bottom cover (2) made of beryllium copper material is inserted and sleeved at the lower part of the lower female die body (10); a concave part (22) and a flow guide groove (23) are formed at the bottom of the die bottom cover (2); and a sealing ring is clamped between the female die bottom cover (2) and the lower female die body (10). The cooling speed of the lower female die is high, the work efficiency is improved, and when the same bottle cap of different customers is manufactured, a manufacturer only needs to replace the die bottom cover, so that the lower female die is very convenient.

Description

The lower cavity die of plastic bottle cap molding press

Technical field:

The utility model relates to bottle cap moulding press technical field, more specifically to a kind of lower cavity die of bottle cap moulding press.

Background technology:

Granted publication CN201483701U discloses a kind of lower cavity die die cavity cooling device of plastic bottle cap molding press, its lower cavity die integrally casting forms, its weak point is: 1, because the lower cavity die integrally casting makes that the lower cavity die cooling velocity is slow, influence speed of production.2, each bottle cap is owing to customized manufacturer's difference, and the literal of the sign producer of bottle cap bottom moulding is different with pattern, and like this, the bottle cap that each client orders need be opened lower cavity die one time, and is very inconvenient.

The utility model content:

The purpose of this utility model is exactly the deficiency at prior art, and a kind of lower cavity die of plastic bottle cap molding press is provided, and its cooling velocity is fast, has improved operating efficiency, and the bottle cap of different clients' same model only needs more that the die change bottom gets final product, and is very convenient.

Technology solution of the present utility model is as follows:

The lower cavity die of plastic bottle cap molding press, comprise the lower cavity die body, form the step ring on the lower cavity die body, step ring and lower cavity die body form and top bar, get out of a predicament or an embarrassing situation, the bottom of getting out of a predicament or an embarrassing situation forms the current guided rings of band opening, the mould bottom sleeve that the beryllium copper material is manufactured is in the bottom of lower cavity die body, and the bottom of mould bottom forms recessed go out portion and guiding gutter, and clamping has sealing ring between mould bottom and the lower cavity die body.

Form the sleeve step on the lower inner wall of described lower cavity die body, form mould bottom step on the mould bottom, mould bottom step is fastened on the sleeve step.

The beneficial effects of the utility model are:

1, the general originally employing punching block of lower cavity die adopts stainless steel material to manufacture, and the utility model adopts the beryllium copper material to manufacture the mould bottom, and the heat conductivity of beryllium copper is better than stainless steel, cools off the time weak point that needs like this, has improved production efficiency.

2, the plastic bottle closure of the same model of producing for different clients, only need more die change bottom, because the bottle cap of the same model that different clients order, just the literal and the pattern of bottle cap bottom are different, more the die change bottom gets final product, producer has saved the die sinking cost like this, simultaneously, uses also very convenient.

Fig. 1 is a cutaway view of the present utility model

Fig. 2 is a perspective exploded view of the present utility model

Fig. 3 changes the perspective exploded view that angle is observed for the utility model

Among the figure: 10, lower cavity die body; 11, step ring; 12, current guided rings; 121, opening; 1a, top bar; 1b, get out of a predicament or an embarrassing situation; 101 sleeve steps; 2, mould bottom; 21, mould bottom step; 22, recessedly go out portion; 23, guiding gutter; 3, sealing ring.

The specific embodiment:

Embodiment: see shown in Fig. 1～3, the lower cavity die of plastic bottle cap molding press, comprise lower cavity die body 10, form step ring 11 on the lower cavity die body 10, step ring 11 forms the 1a that tops bar with lower

cavity die body

10,1b gets out of a predicament or an embarrassing situation, the get out of a predicament or an embarrassing situation bottom of 1b forms the current guided rings 12 of band opening 121, mould bottom 2 sleeves that the beryllium copper material is manufactured are in the bottom of lower cavity die body 10, the bottom of mould bottom 2 forms recessed go out portion 22 and guiding gutter 23, and clamping has sealing ring 3 between mould bottom 2 and the lower cavity die body 10.

Form sleeve step 101 on the lower inner wall of described lower cavity die body 10, form mould bottom step 21 on the mould bottom 2, mould bottom step 21 is fastened on the sleeve step 101.

Operation principle: original stainless steel lower cavity die is divided into two parts, is that material is manufactured mould bottom 2 with the beryllium copper, because the heat conductivity of beryllium copper is better than stainless steel, cools off the time weak point that needs like this, has improved production efficiency.Simultaneously, the bottle cap of different clients' same model only needs more that the die change bottom gets final product, and is very convenient.
