Abstract

The utility model discloses an injection mold with automatic hinging function, which comprises a mold core, a driven gear, a transition gear, a driving gear, a motor, a limit gear, a limit transition gear, a lifting gear, a limit screw, a limited block and limit switches, wherein the driven gear is fixedly sleeved on the lower part of the mold core and meshed with the driving gear by the transition gear, the driving gear is fixedly sleeved on an output shaft of the motor, the motor is connected with the limit screw through the meshing of the limit gear, the limit transition gear and the lifting gear, the limit screw is in threaded connection with the limited block, and the upper and lower sides of the limit screw are respectively provided with a limit switch which can be pressed against the limited block. According to the utility model, because the motor completes an action that the mold core is separated from a product through a power gear pair, and the motor drives the limit screw to rotate through a limit gear pair so as to achieve the purpose of controlling the core-pulling distance, therefore, the injection mold has the advantages of accurate and reliable actions.

Description

Injection mold with automatic hinge tooth function

Technical field

The utility model relates to a kind of mould of plastics, particularly relates to a kind of injection mold with automatic hinge tooth function.

Background technology

Plastic injection mould is an instrument of producing plastic products, uses very extensive.In plastic products injection moulding, because the inside of some plastic products has internal thread, plastic part can't take out from mold cores after moulding.The method that solves at present is to adopt moving core, and after the plastic part moulding, moving core takes out from mould with plastic part, and then tries every possible means core is taken out.Time-consuming, the effort of this method can't satisfy mass-produced requirement.

The utility model content

The purpose of the utility model is to provide a kind of injection mold with automatic hinge tooth function of can disposable completion internal thread loosing core.

For realizing above-mentioned purpose, the technical solution of the utility model is:

The utility model is a kind of injection mold with automatic hinge tooth function, and it comprises quiet mould, dynamic model, core, driven gear, transition gear, driving gear, motor, position limited gear, spacing transition gear, lifter wheel, spacing screw rod, limited block, limit switch; Described die cavity is located between quiet mould and the dynamic model; Core is rotating to be installed on the dynamic model and to stretch into die cavity; Driven gear is fixedly sleeved to be meshed in the bottom of core and with transition gear; Transition gear and driving gear engagement, driving gear is fixedly sleeved on the output shaft of motor, and the body-fixed of motor is in the outside of dynamic model; An also fixedly sleeved position limited gear on the output shaft of motor; This position limited gear is through spacing transition gear and lifter wheel engagement; Lifter wheel is fixed on the spacing screw rod; The limited block that on spacing screw rod, is spirally connected is separately installed with the limit switch that can lean with limited block in the upper and lower both sides of spacing screw rod.

After adopting such scheme; Because the limiting tooth wheel set (being made up of position limited gear, spacing transition gear, lifter wheel) that the utlity model has motor, is used to transmit the power gear secondary (being made up of driven gear, transition gear, driving gear) of the power of loosing core and is used to drive spacing screw rod rotation, motor is accomplished the debentition action of core from product through the power gear pair; Simultaneously, motor drives spacing screw rod rotation through the limiting tooth wheel set, reaches the purpose of controlling the distance of loosing core, has correct, the reliable advantage of action.

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

The specific embodiment

As shown in Figure 5; The utility model is a kind of injection mold with automatic hinge tooth function, and it comprises quiet mould 1 (like Fig. 1, shown in Figure 4), dynamic model 2, core 3, driven gear 4, transition gear 5, driving gear 6, motor 7, position limited gear 8, spacing transition gear 9, lifter wheel 10, spacing screw rod 20, limited block 30, limit switch 401,402 (as shown in Figure 4).

Described die cavity is located between quiet mould 1 and the dynamic model 2, and core 3 is rotating to be installed on the dynamic model 2 and to stretch into die cavity.In conjunction with Fig. 1, shown in Figure 3, driven gear 4 fixedly sleeved at core 3 the bottom and with transition gear 5 engagements, transition gear 5 and driving gear 6 engagements, driving gear 6 is fixedly sleeved on the output shaft of motor 7, the body-fixed of motor 7 is in the outside of dynamic model 2; An also fixedly sleeved position limited gear 8 on the output shaft of motor 7; This position limited gear 8 is through spacing transition gear 9 and lifter wheel 10 engagements; Lifter wheel 10 is fixed in the bottom of spacing screw rod 20; The limited block 30 that on spacing screw rod 20, is spirally connected is separately installed with the limit switch 401,402 (as shown in Figure 4) that can lean with limited block 30 on the upper and lower both sides of spacing screw rod 20, dynamic model 2.

The operation principle of the utility model:

When die sinking, quiet mould 1 separates with dynamic model 2, and motor 7 is accomplished the debentition action of core 3 from product through power gear secondary (being made up of driven gear 4, transition gear 5, driving gear 6); Simultaneously; Motor 7 drives spacing screw rod 20 rotations through limiting tooth wheel set (being made up of position limited gear 8, spacing transition gear 9, lifter wheel 10); Driving limited block 30 moves up and down; When limited block 30 on upper and lower top or bottom when leaning upper and lower limit bit switch 401,402, motor 7 quits work, thereby reaches the loose core purpose of distance of control.

The emphasis of the utility model just is: adopt motor to loose core.

The above; Be merely the utility model preferred embodiment; So can not limit the scope that the utility model is implemented with this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
