Description

Without rising head glass mold mould bottom mold package

Technical field

This utility model is related to a kind of glass mold mold package, and more particularly to one kind is without rising head glass mold mould uphill casting type Component, belongs to glass mold production technical field.

Background technology

The mould bottom structure of glass mold is as shown in figure 1, generally including first round platform 1 being relatively large in diameter and being arranged at Less second round platform 2 of diameter thereon, 1 bottom surface of the first round platform are plane, and the upper surface of the second round platform 2 set according to specific needs It is set to plane or projection.Existing glass mold mould uphill casting type is as shown in Fig. 2 running castings include molding mold cavity 3, molding casting The upper diameter in chamber 3 is more than lower diameter, and in step-like, top is used for the first round platform of molding, and bottom is used for the second round platform of molding, 4 entrance of ingate is arranged on lower sides, and 4 bottom surface of ingate is flushed with 3 bottom surface of molding mold cavity, and the top of molding mold cavity 3 is arranged The rising head 5 connected with molding mold cavity 3.During cast, alloy molten solution from ingate flow into molding mold cavity bottom and from bottom to top up to Alloy molten solution enters rising head and liquid level stops the injection of alloy molten solution when exceeding riser height half.Prior art subject matter exists In needing to arrange a rising head for making up the shrinkage cavity defect of the first round platform bottom surface for each molding mold cavity, increase alloy materials It is many, while for the presence of rising head, the first round platform bottom surface separately need to process, increase production cost.

Utility model content

For problem of the prior art, this utility model provides a kind of without rising head glass mold mould bottom mold package, solution Certainly alloy materials are more simultaneously for the first round platform bottom surface defect, and the first round platform bottom surface individually need to process and surface quality of continuous castings defect is more Problem.

Technical solutions of the utility model are as follows：One kind without rising head glass mold mould bottom mold package, including what is cooperated Upper mold and lower mold, the lower mold are provided with intermediate cavity, are provided with multiple molding mold cavities, the molding casting around the intermediate cavity Chamber is up big and down small stepped cylindrical chamber, and the top sidewall of the molding mold cavity is connected with intermediate cavity by ingate, it is described in Between chamber be provided with cast passage, the molding mold cavity, ingate, intermediate cavity and cast passage top surface be opening shape, it is described on The bottom surface of casting mold be plane, the upper mold intermediate cavity correspondence position arrange rising head.

Preferably, the quantity of the molding mold cavity at the mould bottom is 3.

Preferably, the intermediate cavity is identical with the length of the ingate that the molding mold cavity at some mould bottoms is connected.

Preferably, the intermediate cavity is cylindrical cavity of the bottom surface in dome-type.

Preferably, the ingate depth is less than intermediate cavity depth.

The advantage of technical scheme provided by the utility model is that original each molding mold cavity is arranged a rising head Being changed to the shared rising head of multiple molding mold cavities carries out feeding, reduces alloy dosage, reduces cost；While the top of molding mold cavity After face no longer sets rising head, i.e. mould bottom pour mold injection forming, bottom surface directly forms smooth flat, without the need for reprocessing, further reduces cost； The sprue gate of ingate moves to top, and the riser feeding of the intermediate cavity connected by ingate from molding mold cavity bottom, changes Original foundry goods cooling order, mould casting few surface defects.

Specific embodiment

With reference to embodiment, the utility model is described in further detail, but not as to restriction of the present utility model.

Disclosed in the present embodiment without rising head glass mold mould bottom mold package as shown in Figure 3,4, including 10 He of upper mold Lower mold 11, upper mold 10 and lower mold 11 are applied in combination.The central authorities of wherein lower mold 11 are provided with intermediate cavity 12, and intermediate cavity 12 is Cylindrical cavity of the bottom surface in dome-type.Multiple molding mold cavities 13 for the molding of mould bottom are set around intermediate cavity 12, the present embodiment is adopted With 3 molding mold cavities 13, particular number suitably can be adjusted.Molding mold cavity 13 be up big and down small stepped cylindrical chamber, top side Wall is connected with intermediate cavity 12 by ingate 14.In order to ensure multiple molding mold cavities 13 while cast, connects each molding mold cavity 13 14 identical length of ingate is same, and 14 depth of ingate is less than 12 depth of intermediate cavity.Intermediate cavity 12 is additionally provided with closes for pouring into a mould The cast passage 15 of golden liquation.When upper mold 10 is not combined with lower mold 11, molding mold cavity 13, ingate 14, intermediate cavity 12 Opening shape is with the top surface of cast passage 15.The bottom surface of upper mold 10 is plane, is arranged in the correspondence position of intermediate cavity 12 Rising head 16.When upper mold 10 is combined with lower mold 11, molding mold cavity 13 and 14 top of ingate are opened by the bottom surface of upper mold 10 Mouth closing, intermediate cavity 12 combine connection with rising head 16.

Casting process as shown in figure 5, during cast alloy molten solution by passage 15 is poured into a mould into intermediate cavity 12, then through 3 Ingate 14 enters 3 molding mold cavities 13 simultaneously, and flows down from the top of molding mold cavity 13, when alloy molten solution gradually fills molding casting During chamber 13, alloy molten solution initially enters rising head 16, and alloy molten solution stops cast when exceeding 16 height 1/2nd of rising head, is cooled to The runner that type, separating casting and ingate 14 are formed.
