Abstract

A formed sliding block mechanism with an insert comprises a fixed die core, a movable die core matched with the fixed die core, a sliding block matched with the movable die core, and a locking block for locking the sliding block in a die closing state. An inclined guide pillar with the guiding function during die opening/closing process is fixed on the fixed die core; a material placement position for placing the insert is arranged on the movable die core; a material accommodating hole for accommodating the insert is formed at the head of the sliding block, and a guide pillar groove matched with the inclined guide pillar is formed on the sliding block; the inclined guide pillar is incomplete cylindrical, the side surface of the inclined guide pillar close to the fixed die core is a cylindrical surface, and the other side thereof is a notch; and the guide pillar groove is a U-shaped groove positioned at the tail end of the sliding block, and an elastic buckle is arranged on the side wall of the U-shaped groove. The utility model has the advantages of low requirement for processing precision of the insert and low requirement for installation precision, and can ensure the smooth die closing operation, and improve the qualification rate of the formed sliding block mechanism.

Description

A kind of slide block mechanism with the inserts moulding

Technical field

The utility model relates to a kind of slide block mechanism with the inserts moulding.

Technical background

When making the plastic product of band inserts, need earlier inserts to be placed in the mould, carry out injection moulding again.Traditional way as shown in Figure 1 and Figure 2, Fig. 1 is the state after the traditional moulds die sinking, Fig. 2 is the state behind the traditional moulds matched moulds.At first will move, cover half opens, inserts A0 is placed among the mavable module core A2, then matched moulds; During matched moulds, Angle Pin A3 is inserted into and is positioned at slide block A1 upper guide post groove A12, and slide block A1 moves along the Angle Pin A3 on the cover half benevolence A4, inserts A0 is inserted into the hole A11 that is positioned at slide block A1 head, can holds inserts A0, at this moment, moving, cover half closes, the slide block A1 piece A5 locking that is locked; And then injection mo(u)lding.But, there is following shortcoming in this traditional mould: be difficult to 1, guarantee that Angle Pin successfully inserts in the guide pillar groove, relative position moving, cover half has deviation promptly may cause Angle Pin can't insert in the guide pillar groove slightly, or inserts can't be inserted in the slide block fully, cause product percent of pass low, even mold damage; 2, be difficult to guarantee that inserts successfully is inserted in the hole on the slide block, cause the required precision height of inserts own, the perpendicularity of inserts and profile tolerance need reach 0.03mm, the product rejection rate height that causes inserts mould and die accuracy height and production inserts, in case inserts does not insert in the slide block smoothly, then can cause slide block and die to damage by pressure, make product defective.

Summary of the invention

For overcoming the above-mentioned shortcoming of prior art, the utility model provides that a kind of inserts requirement on machining accuracy is low, installation accuracy requires lowly, can guarantee the smooth matched moulds of mould, improve the slide block mechanism of the band inserts moulding of product percent of pass.

A kind of slide block mechanism with the inserts moulding comprises cover half benevolence, is fixed with the Angle Pin that play the guiding role when the folding mould on the described cover half benevolence;

With the mavable module core that described cover half benevolence cooperates, described mavable module core is provided with the blowing place of placing inserts;

With the slide block that described mavable module core cooperates, the head of described slide block is provided with the materials-containing hole that holds aforesaid inserts, and described slide block is provided with the guide pillar groove that cooperates with described Angle Pin;

The matched moulds state is the latch segment of the described slide block of locking down;

It is characterized in that: described Angle Pin is one incomplete cylindrical, and the side of the close described cover half benevolence of described Angle Pin is the face of cylinder, and opposite side is a breach;

Described guide pillar groove is the U type groove that is positioned at slider tail,, the sidewall of described U type groove is provided with elasticity and buckles.

Further, described breach is the curved surface of a plane or indent.

Further, described elasticity button comprises plug on the sidewall that is fixed on described U type groove and the limited post that cooperates with described Angle Pin, and described plug is connected with described limited post by spring.

Further, head described limited post, that cooperate with described Angle Pin is for spherical.

Further, described elasticity button is arranged on two sidewalls of described U type groove symmetrically.

Technical conceive of the present utility model is: at first will move, cover half opens, inserts is installed in the blowing place of mavable module core, manually promote slide block again, can guarantee successfully to be inserted into aforesaid inserts in the materials-containing hole, thereby make slide block and mavable module core form an integral body, again this integral body is advanced to Angle Pin, in Angle Pin enters the guide pillar groove fully, the integral body that slide block and mavable module core form is moved along Angle Pin, finishes up to matched moulds.

When Angle Pin entered the guide pillar groove, face of cylinder part contacted with limited post before this, promoted limited post gradually and inwardly contracted, and spring is in compressive state; After in Angle Pin enters the guide pillar groove fully, spring reset, limited post contacts with planar section, and Angle Pin is locked in the guide pillar groove.

The utlity model has that the inserts requirement on machining accuracy is low, installation accuracy requires lowly, can guarantee the smooth matched moulds of mould, improve the advantage of product percent of pass.

The specific embodiment

With reference to accompanying drawing, further specify the utility model:

A kind of slide block mechanism with the inserts moulding comprises cover half benevolence 4, is fixed with the Angle Pin 3 that play the guiding role when the folding mould on the described cover half benevolence 4;

With the mavable module core 2 that described cover half benevolence 4 cooperates, described mavable module core 2 is provided with the blowing place 21 of placing inserts 6;

With the slide block 1 that described mavable module core 2 cooperates, the head of described slide block 1 is provided with the materials-containing hole 11 that holds aforesaid inserts 6, and described slide block 1 is provided with the guide pillar groove 12 that cooperates with described Angle Pin 3;

The matched moulds state is the latch segment 5 of the described slide block 1 of locking down;

Described Angle Pin 3 is one incomplete cylindrical, and the side of the close described cover half benevolence 4 of described Angle Pin 3 is the face of cylinder, and opposite side is a breach 31;
