Description

Mould

Technical field

The utility model relates to a kind of mould, relates in particular to a kind of good mould of sealing with cooling device.

Background technology

Current, very variation of required daily product in the daily life, wherein plastic product is seen everywhere in people's life especially, for example electronic product casing, plastic cup, game pad or the like such as phone housing.After processing need be with plastic molting during these products, pour in the mould, back to be formed cooling die sinking just can obtain needed product.

Conventional molds generally comprises master mold, male model, is arranged at the mold insert between master mold and the male model, and the cooling device that is used to cool off this mold insert.Cooling tower is arranged among the mold insert, and cooling water forms cooling circuit between water tower, utilizes heat conducting principle, thereby realizes the cooling purpose.Often, fix through fixtures such as screws between cooling device and the male model, yet, only there are the fixing current that can't guarantee of screw to seal the phenomenon that tends to leak.For improving sealing, existing anti-design of leaking commonly used generally is provided with throat taps and copper plug between cooling tower and male model.Yet, three or above throat taps or copper plug often need be set just can reach better seal property.Therefore, this kind design is very complicated, consuming time on the installation and removal operation, efficient is low, does not meet the needs of production.

The utility model content

The purpose of the utility model is that the deficiency to above-mentioned prior art provides a kind of simple in structure, easy for installation, mould with cooling device that sealing is good.

Be to realize above-mentioned purpose, the mould that the utility model provided comprise tabling master mold and male model, be arranged at the mold insert between said master mold and the said male model, and the cooling device that is used to cool off said mold insert.Wherein, said cooling device comprises at least one water tower of being arranged within the said mold insert, be arranged among the said water tower and be divided into the water-stop sheet of two connection water channels to said water tower, and the water inlet pipe and the outlet pipe that are connected respectively with said water tower and external equipment; Periphery in the end that said water tower and said male model connect is provided with a sealing ring, to realize sealing.

As stated, the mould of the utility model is equipped with sealing ring in the outer periphery of the end of water tower and male model butt joint, therefore, can not have the space between water tower and the male model plate, thereby form seal cavity, prevents to leak.And the utility model replaces throat taps commonly used and copper plug to realize sealing with sealing ring, and is simple in structure, assembling is more convenient, thus the shortening process-cycle.

The specific embodiment

By the technology contents, the structural feature that specify the utility model, realized purpose and effect, know clearly below in conjunction with embodiment and conjunction with figs. and give explanation.

Please refer to Fig. 1,2, the mould 1 of the utility model comprises the master mold 11 of tabling, male model 12, is arranged at the mold insert 13 between master mold 11 and the male model 12, and the cooling device 14 that is used to cool off this mold insert 13.

Particularly, this master mold 11 comprises die holder 111 and is fixed in the caster 112 on this die holder 111, is provided with a mother module core (figure does not show) in this caster 112 to accommodate this mold insert 13.This male model 12 comprises male model fixed head 121, is fixed in two cushion blocks 122 on this male model fixed head 121, and the male model plate 123 that links to each other with two cushion blocks 122.Please refer to Fig. 1 and Fig. 3, this male model plate 123 is provided with depression 124, and an accepting groove 125 is set in this depression 124, and this accepting groove 125 is round.In addition, also be provided with two through hole 126 in the depression 124.

This mold insert 13 comprises hollow bulb 131, top 132 and bottom 133, and particularly, this top 132 is contained among the mother module core of caster 112, and this bottom 133 is fixed among the depression 124 of male model plate 123.Wherein, bottom 133 fixes with male model plate 123 through a screw 134.

In conjunction with Fig. 2, Fig. 4 and Fig. 5; This cooling device 14 comprises at least one water tower 141 among the hollow bulb 131 that is arranged at mold insert 13; Be arranged among the water tower 141 and and be divided into two water-stop sheets 142 that are communicated with water channel 141a and 141b water tower 141, and the water inlet pipe 143 and the outlet pipe 144 that link to each other with external equipment with this water tower 141.In the present embodiment, cooling device 14 comprises integrated four said water towers 141, and the quantity of water tower 141 and water-stop sheet 142 is respectively four.Wherein, be provided with communication passage 145 in its underpart between four water towers 141, so that four water towers 141 form physical connection, cooling water feeds in any one water tower 141 therein, and arrives other other three water towers 141, communicates and circulates thereby form.Particularly; Show like Fig. 4 and Fig. 5; Water inlet pipe 143 and outlet pipe 144 are formed at the below of the depression 124 of male model plate 123 respectively, and this water inlet pipe 143 links to each other with two connection water channel 141a, 141b of water tower 141 through two through holes 126 on the depression 124 with outlet pipe 144.

As the design of the utility model, as shown in Figure 5, in the periphery of the water tower 141 and the end of male model plate 123 butt joints one sealing ring 15 is set; When the mold insert that accommodates water tower 141 13 is fixed in the depression 124 of male model plate 123 through screw 134; Sealing circle 15 holds in the accepting groove 125 that is embedded on the depression 124, therefore, does not have the space between water tower 141 and the male model plate 123 and exists; Form seal cavity, prevent to leak.

In conjunction with Fig. 4, Fig. 5, when cooling water when water inlet pipe 143 gets into, through the connection water channel 141a entering water tower 141 that links to each other with this water inlet pipe 143; Owing to be connected between the water tower 141; Therefore, cooling water forms circulation between water tower 141, and the direction of arrow shown in Figure 6 is the direction of current.At last, flow out from outlet pipe 144 through being communicated with water channel 141b through the current after the circulation.So back and forth, to realize the purpose of cooling mold insert 13.

In sum,, therefore, can there be the space between water tower 141 and the male model plate 123, thereby forms seal cavity, prevent to leak because the outer periphery of the mould 1 of the utility model in the water tower 141 and the end of male model plate 123 butt joints is equipped with sealing ring 15.And the utility model replaces throat taps commonly used and copper plug to realize sealing with sealing ring 15, and is simple in structure, assembling is more convenient, thus the shortening process-cycle.
