Abstract
The invention discloses a plastic mold structure with a conveniently processed pin-point gate. The plastic mold structure is characterized by comprising an upper mold body, wherein a mounting hole is formed at the wounding inlet of the upper mold body; and a machined and molded pin-point gate casting piece is inlaid in the mounting hole. The plastic mold structure with the conveniently processed pin-point gate is characterized in that the pin-point gate casting piece comprises a casting piece body, wherein a runner is machined in the casting piece body; and a submarine gate communicated with the runner is formed at one end of the casting piece body. The invention aims to overcome the defects in the prior art and provides the plastic mold structure with the conveniently processed pin-point gate, and the plastic mold structure is simple in structure, convenient to process and relatively low in processing cost.
Description
Technical field
The present invention relates to the plastic rubber mold structure at the thin mouth of a river of a kind of convenient processing.
Background technology
Existing thin mouth of a river plastic mould, its runner and advance cast gate and generally all design at the patrix die adds and wants whole die discharge man-hour, if running into that large mold processes will be very difficult, expends a large amount of process times, increases processing cost.
Summary of the invention
The objective of the invention is provides a kind of simple in structure, easy to process in order to overcome weak point of the prior art, the plastic rubber mold structure at the thin mouth of a river of convenient processing that processing cost is relatively low.
In order to achieve the above object, the present invention adopts following scheme:
The plastic rubber mold structure at the thin mouth of a river of a kind of convenient processing, it is characterized in that: include upper cores, advance around locating to be provided with an installing hole in described upper cores, foundry goods is watered at the good thin mouth of a river to stud with machine-shaping in described installing hole.
The plastic rubber mold structure at the thin mouth of a river of aforesaid a kind of convenient processing, it is characterized in that the described thin mouth of a river waters foundry goods and include and water the foundry goods body, be processed with runner described watering in the foundry goods body, be provided with the cast gate that advances that is connected with described runner at described foundry goods body one end that waters.
The plastic rubber mold structure at the thin mouth of a river of aforesaid a kind of convenient processing is characterized in that the described foundry goods body that waters is cylinder, and the interior part body upper end of casting without leave of described runner diminishes gradually to watering foundry goods body lower end.
The plastic rubber mold structure at the thin mouth of a river of aforesaid a kind of convenient processing is characterized in that being provided with a boss in the described foundry goods body lower end of watering, and describedly advances cast gate and is arranged on the described boss, and the described cross section of advancing cast gate is that isosceles are trapezoidal.
The plastic rubber mold structure at the thin mouth of a river of aforesaid a kind of convenient processing is characterized in that being provided with positioning step in described installing hole upper end, waters the foundry goods upper end at the described thin mouth of a river and is provided with the limit convex edge, and described limit convex is along being arranged on the described positioning step.
In sum, the present invention with respect to its beneficial effect of prior art is:
The present invention is simple in structure, and the foundry goods body that waters that adopts high hardness material to make is compared the advantage that has more wear-resistant with the internal mold material, also can take out independent processing, thereby solve the unmanageable problem of large mold.Effectively reduce production cost.
Description of drawings
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is the enlarged drawing at A place among Fig. 1;
Fig. 3 is that one of stereogram of foundry goods is watered at the thin mouth of a river;
Fig. 4 is two of the thin mouth of a river stereogram that waters foundry goods.
The specific embodiment
The invention will be further described below in conjunction with description of drawings and the specific embodiment:
The plastic rubber mold structure at the thin mouth of a river of a kind of convenient processing as shown in Figures 1 to 4 includes upper cores 1, advances around locating to be provided with an installing hole in described upper cores 1, and foundry goods 2 is watered at the good thin mouth of a river to stud with machine-shaping in described installing hole.
The thin mouth of a river of the present invention is watered foundry goods 2 and is included and water foundry goods body 21, is processed with runner 22 in the foundry goods body 21 described watering, described water foundry goods body 21 1 ends be provided be connected with described runner 22 advance cast gate 23.
The foundry goods body 21 that waters described in the present invention is cylinder, and interior part body 21 upper ends of casting without leave of described runner 22 diminish gradually to watering foundry goods body 21 lower ends.
Wherein be provided with a boss 24 in described foundry goods body 21 lower ends of watering, describedly advance cast gate 23 and be arranged on the described boss 24, the described cross section of advancing cast gate 23 is that isosceles are trapezoidal.
Be provided with positioning step in described installing hole upper end among the present invention, water foundry goods 2 upper ends at the described thin mouth of a river and be provided with limit convex along 3, described limit convex is arranged on the described positioning step along 3.
The present invention is simple in structure, and the foundry goods body that waters that adopts high hardness material to make is compared the advantage that has more wear-resistant with the internal mold material, also can take out independent processing, thereby solve the unmanageable problem of large mold.Effectively reduce production cost.
