Abstract
The utility model relates to the field of injection molding equipment, and in particular relates to a differential type gate shearing device. The technical problem to be solved is to provide the differential type gate shearing device for realizing separation of side gate runner waste and a finished product. The differential type gate shearing device comprises a bottom die, a side gate runner communicated with the bottom die, a bottom die push rod arranged on the wall surface of the bottom die and a gate waste push rod arranged on the wall surface of the side gate runner, wherein the bottom die push rod is driven by a bottom die driving device; the gate waste push rod is driven by a gate waste driving device; the bottom die driving device and the gate waste driving device are used for driving the corresponding push rods successively. The gate waste push rod is driven by the gate waste driving device, and the bottom die driving device and the gate waste driving device are used for driving the corresponding push rods successively, thus driving difference of driving effect exists to cause that side gate runner waste originally fixed on the finished product is broken. The differential type gate shearing device can be applied to production occasions of cutting off the side gate runner waste on the injection molding finished product.
Description
Technical field
The utility model relates to injection-moulding device field, especially a kind of differential type cast gate shear.
Background technology
In the design of injection-moulded plastic part module, the application of side gate is comparatively general.Because side gate form structure is simple, be easy to processing, repair, and processing cost is low, is easy to guarantee forming parts, thereby use more general.But side gate has again its drawback: 1, plastic parts moulding rear side waters runner waste material needs manually separated with plastic, and need the artificial cast gate position burr of removing, therefore the production efficiency of side gate plastic is lower, need to consume and remove man-hour, and the impact that is subject to human factor of the surface quality situation at cast gate position, geometry, likely there is burr and the plastics chip of not cleaning out.Will cause harmful effect to follow-up assembling, the end product quality of product like this.Thereby some side gate moulding plastic also wants application specific two class instruments to cut the tumbling operation after cast gate and deburring after moulding, therefore the subsequent handling of moulding is more, increased processing cost, reduced production efficiency and quality and be difficult for guaranteeing.2, after moulding, plastic never has good scheme with the burr removing at the separated of runner scrap and cast gate position, is mainly still manual operation.Realize automatic shearing separated runner scrap, for raising the efficiency, ensuring the quality of products, seem particularly important.
Utility model content
Technical problem to be solved in the utility model is to provide the differential type of drive of a kind of employing and shears side and water runner waste material, thereby realize, side is watered to the runner waste material differential type cast gate shear separated with finished product.
The utility model solves the technical scheme that its technical problem adopts: differential type cast gate shear: comprise that bed die and the side communicating with bed die water runner, also be arranged at the bed die push rod on bed die wall and be arranged at side and water the cast gate waste material push rod on runner wall, bed die push rod drives by bed die drive unit, cast gate waste material push rod drives by cast gate waste material drive unit, the push rod that described bed die drive unit is corresponding with the first rear drive of cast gate waste material drive unit.
Further, described bed die push rod consists of bed die push rod head and bed die top rod driving bar.
Further, described cast gate waste material push rod consists of cast gate waste material push rod head and cast gate waste material top rod driving bar.
The beneficial effects of the utility model are: the utility model arranges first respectively bed die push rod on bed die wall, with watering in side, cast gate waste material push rod is set on runner wall, because bed die push rod drives by cast gate waste material drive unit, cast gate waste material push rod drives by cast gate waste material drive unit, and the push rod that described bed die drive unit is corresponding with the first rear drive of cast gate waste material drive unit, therefore have tandem driving difference in driving effect, exactly because this drives difference to water runner waste material and fracture being originally fixed on side on finished product, thereby the object of runner waste material cutting and separating is watered finished product and side in realization.The utility model is ingenious utilizes the effect that bed die push rod and cast gate waste material top rod driving time difference bring, and side is watered to runner waste material and fracture, and the utility model can be applied to cut off the production occasion that injection-molded finished upside waters runner waste material.
Accompanying drawing explanation
Fig. 1 is the schematic diagram before the utility model drives.
Fig. 2 is that the utility model starts to drive also side the most at last to water the runner waste material schematic diagram separated with finished product.
In figure, be labeled as: bed die 1, finished product 11, bed die push rod 12, bed die push rod head 121, bed die top rod driving bar 122, side are watered runner 2, side is watered runner waste material 21, cast gate waste material push rod 22, cast gate waste material push rod head 221, cast gate waste material top rod driving bar 222.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Differential type cast gate shear as shown in Figure 1 and Figure 2: comprise that bed die 1 and the side communicating with bed die 1 water runner 2, also comprise the bed die push rod 12 being arranged on bed die 1 wall and be arranged at side and water the cast gate waste material push rod 22 on runner 2 walls, bed die push rod 12 drives by bed die drive unit, cast gate waste material push rod 22 drives by cast gate waste material drive unit, the push rod that described bed die drive unit is corresponding with the first rear drive of cast gate waste material drive unit.
In actual applications, need to consider the arrangement of bed die push rod 12 and cast gate waste material push rod 22 in equipment, and side waters the factors such as angle that runner 2 enters bed die 1, deciding is that first bed die drive unit drives, or first cast gate waste material drive unit drives.Experience in conjunction with practice, in general, can pay the utmost attention to cast gate waste material drive unit and drive the mode that first drives cast gate waste material push rod 22, first side be watered to runner waste material 21 disconnected from finished product 11 tops, and then drive bed die push rod 12 that finished product 11 is ejected by bed die drive unit.For the layout of bed die drive unit and cast gate waste material drive unit position, under its prerequisite that drives function, with the principle of simplified apparatus, carry out guaranteeing.
In order to simplify the structure of bed die push rod 12, can select such scheme: described bed die push rod 12 consists of bed die push rod head 121 and bed die top rod driving bar 122.As shown in Figure 2, bed die push rod head 121 ejects finished product 11 from bed die 1, and bed die top rod driving bar 122 is delivered to bed die push rod head 121 places by the driving force from bed die drive unit.
Design based on same, also can select such scheme: described cast gate waste material push rod 22 consists of cast gate waste material push rod head 221 and cast gate waste material top rod driving bar 222.Same principle, it is disconnected from finished product 11 tops that cast gate waste material push rod 22 waters runner waste material 21 by side, and cast gate waste material top rod driving bar 222 is delivered to cast gate waste material push rod head 221 places by the driving force from cast gate waste material drive unit.
