Description
Technical field
The present invention relates to automobile fitting manufacture field, plastics part mould is specifically referred to.
Background technology
Existing injection mold typically pours the plastics after fusing in casting from mould when the plastic fittings of automobile is processed, and the demoulding will obtain required product after cooling to be formed.
But, injection mold when the deep accessory of some shaping bit comparisons is molded, occur when the accessory demoulding stick on mould and cause accessory be broken cannot the smooth demoulding situation.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, there is provided plastics part mould, can smoothly realize the demoulding work of automobile fitting plastic product.
The purpose of the present invention is achieved through the following technical solutions：
Plastics part mould, including upper mould and the lower mould with the mutual corresponding matching of upper mould；Upper mould includes upper die plate, is arranged at the push pedal below upper die plate, and is fixed on upper die plate lower surface and through the upper cores of push pedal；Lower mould includes lower template, lead column and spring, and forming cavity corresponding with upper cores and pilot hole are offered in lower template, and lead column is slidably matched with pilot hole, and spring is arranged in pilot hole and support guide post, and lead column is supported to push pedal；Also include cooling water pipe, cooling water pipe includes the cooling section being arranged in upper cores, the inlet segment and water exit end that are arranged in upper die plate；One end of inlet segment is extended to outside upper die plate, and the other end of inlet segment is connected with the water inlet end of cooling section；One end of water exit end is extended to outside upper die plate, and the other end of water exit end is connected with the water side of cooling section.
Operation principle is as follows：In matched moulds, upper cores are stretched into is molded the high temperature plastics in forming cavity in forming cavity.During die sinking, the plastic product after shaping is attached in upper cores, and forming cavity is left with upper cores.Push pedal is withstood on lead column the lower surface of upper die plate under the action of the spring.Now, cooling water is flowed into by inlet segment, and the plastic product being attached in upper cores is cooled down when cooling water is by cooling section, intensity increase after plastic product cooling.As upper mould is continued up, the elastic force of spring is gradually reduced, and lead column is gradually reduced to the power that push pedal applies, and push pedal under gravity stops that plastic product is continued up, and so as to plastic product is pushed away into upper cores, realizes the demoulding.The present invention carries out the demoulding after being cooled down to plastic product, overcomes the problem that forced stripper mechanism causes plastic product to deform.
Further, the cooling section is spirality.Cooling section is spirality, makes temperature conduction area bigger, improves cooling effectiveness.
Further, the also electromagnet cut off valve A including being arranged on water exit end；Electromagnet cut off valve A is closed in matched moulds, is opened in die sinking.Electromagnet cut off valve A is closed during matched moulds, the cooling water in cooling section is stopped flowing, high temperature plastics during matched moulds in forming cavity will not be cooled, it is to avoid the shaping of influence plastic product.
Further, the also electromagnet cut off valve B including being arranged on inlet segment；Electromagnet cut off valve B is closed in matched moulds, is opened in die sinking.Electromagnet cut off valve B is closed during matched moulds, the cooling water in cooling section is stopped flowing, high temperature plastics during matched moulds in forming cavity will not be cooled, it is to avoid the shaping of influence plastic product.
In sum, the advantages of the present invention are：
1st, the present invention carries out the demoulding after being cooled down to plastic product, overcomes the problem that forced stripper mechanism causes plastic product to deform.
2nd, electromagnet cut off valve A and electromagnet cut off valve B is closed during matched moulds, the cooling water in cooling section is stopped flowing, high temperature plastics during matched moulds in forming cavity will not be cooled, it is to avoid the shaping of influence plastic product.
3rd, cooling section is spirality, makes temperature conduction area bigger, improves cooling effectiveness.
