Description

Technical Field

[0001] This application belongs to the technical field of metal part processing equipment, and particularly relates to an automatic casting equipment for T-shaped connectors. Background Art

[0002] Chinese Patent CN201910086849.8, a forming equipment for T-shaped connectors and its processing method, discloses a technical solution that uses a reusable metal core and provides a set of production equipment that cooperates with the core to achieve semi-automatic production of T-shaped connectors. In this technical solution, it is disclosed that "the core includes a first side mold, a second side mold, and a core part. The first side mold is symmetrically connected to both sides of the core part, and the second side mold is symmetrically arranged on both sides of the core. A second arc-shaped protrusion is provided on the upper part of the second side mold. The second arc-shaped protrusion is cooperatively connected with the core part to form a stable closed structure. The second arc-shaped protrusion is fixedly connected with a guide rod. The function of the guide rod is to enable the processed T-shaped joint product to be taken out along the guide rod, avoiding product slippage and damage due to unstable clamping during the taking-out process, and also making the clamping more convenient", and "above the limit baffle, there is a movable part. The movable part is an L-shaped movable part, and one end of the movable part is provided with a knocking part. The knocking part is correspondingly arranged below the second connecting rod and impacts the second limiting part during the processing. Through the action of the knocking part of the movable part, when the second connecting rod is driven to jack up, the bottom of the second connecting rod can be knocked, causing the second connecting rod to vibrate, and at the same time, the vibration is transmitted to the components of the core connected to the second connecting rod, so that the cast product is loosened from the core under the vibration, which is more conducive to the separation of the product from the core". However, in the actual production and processing process, the effect of separating the product from the core provided by the above technical solution by only knocking the bottom of the second connecting rod is not good. Often, it is necessary to manually knock the guide rod with a hammer, etc., to drive the second side mold and the metal T-shaped connector to vibrate through the guide rod, so as to achieve the complete separation between the metal T-shaped connector and the core, and then the metal T-shaped connector can be clamped out from the core. The degree of automation is low.

[0003] Moreover, it is difficult to control the force of manual external force knocking. Often, it is necessary to knock the guide rod multiple times to achieve the complete separation between the T-shaped connector and the core, which reduces the production efficiency. At the same time, this kind of artificial external force knocking will cause irreversible deformation of the core and the equipment components connected to the core, reduce the service life of the core, increase the maintenance cost of the production equipment, and have a greater impact on the precision of the shape of the casting product. After such operation for a long time, the yield rate of the product will also decrease. Summary of the Invention

[0004] In view of this, aiming at the deficiencies of the prior art, the present application provides an automatic casting device for T-shaped connectors. The present invention has made a creative improvement on the basis of the prior art. In the device of the present application, there is no need to set guide rods for the core. Only by driving the core through the device can the complete separation between the metal T-shaped connector and the core be achieved, avoiding the operation of manual knocking. Clamping can be carried out after casting is completed, saving time and effort, and improving the automation degree of the device; at the same time, the service life of the core can be effectively improved, the maintenance cost of the device can be reduced, and the qualified rate of products can be guaranteed.

The second push rod of the present invention can provide more and more stable driving force compared with the round rod in the prior art, and can push the product and the second side mold to move upward together.

[0019] Furthermore, first mounting holes are symmetrically arranged in the first push plate. On one side of the first mounting holes, third mounting grooves are symmetrically arranged. A limiting shaft is arranged in the third mounting groove, and the limiting shaft penetrates through the limiting hole. Particularly, the arc transition portion of the second push rod of the present invention will cooperate with the guiding groove of the guiding block arranged on the support plate frame. With the arrangement of the arc-shaped end below the rod body, the rod body can rotate a certain angle in the first mounting hole along the limiting shaft, realizing the contraction of the side mold of the mold core inside the casting product, causing the second push rod to deviate from the original movement track and move inward, and then the second push rod continues to rise to a predetermined position, enabling the casting mold core to be completely separated from the product.

[0020] Furthermore, the support plate frame is symmetrically provided with first mounting grooves. Opposite sides in the first mounting grooves are provided with first through holes. Second through holes are symmetrically arranged on both sides of the first mounting grooves, and a guiding block is arranged on one side of the second through holes. The first push rod can penetrate through the first through hole and be connected to the lower part of the first side mold of the mold core, and the second push rod can penetrate through the second through hole and be connected to the lower part of the second side mold of the mold core.

[0021] Particularly, through holes are respectively arranged in the first push plate, the first push pressure plate, the second push plate, and the second push pressure plate for the installation of the first push rod, the second push rod, the limiting column, the driving rod, and the driving shaft center.

[0022] Furthermore, a second mounting groove is arranged in the first mounting groove. A second mounting hole is arranged in the second mounting groove, and a bolt is arranged in the second mounting hole; the bolt is in threaded connection with the first threaded hole of the second connecting portion below the mold core portion of the mold core.

[0023] Furthermore, a guiding groove is arranged on one side of the guiding block, and the guiding groove can cooperate with the arc transition portion to displace the second push rod deviating from the original movement path.

[0024] Furthermore, a convex portion is arranged on one side of the slider. An inverted slope is arranged above the convex portion, and the lower part of the convex portion can be connected with the hook portion in a matching manner.

[0025] Further, an inclined guide surface is provided below the limit guide block, and the inclined guide surface can cooperate with the reverse slope to push the convex portion of the slider inward, causing the slider to move inward along the first sliding groove of the second push plate, compressing and deforming the spring portion. At the same time, the slider is decoupled from the hook portion, restricting the displacement distances of the second push plate and the second push pressure plate.

[0026] Further, the lifting drive mechanism includes a drive portion, the drive portion is connected with a drive axis, drive rods are arranged on opposite sides around the drive axis, the drive axis penetrates through the lifting portion, one end of the drive axis is detachably and fixedly arranged in the first push plate, and the drive rods are respectively connected with the four ends of the lifting portion.

[0027] The working process of the inclined ejection and core pulling device of the present invention is as follows: After being cooperatively connected with the casting die core, in the first step, power is provided by the lifting drive mechanism, so that under the action of the drive portion, the drive axis drives the first push plate to drive the first push pressure plate to rise. At the same time, under the action of the hook portion, the hook portion drags the convex portion of the slider to pull up the second push plate, and at the same time drives the second push pressure plate to rise. At this time, the whole lifting portion moves upward along the drive rod; under the action of the lifting portion, the first push rod and the second push rod are displaced upward, ejecting the first side mold and the second side mold of the die core from the die core portion by a certain distance; in the second step, the drive axis continues to rise under the action of the drive portion, and the hook portion continues to displace along the sliding groove of the limit guide block. At this time, the inclined guide surface of the limit guide block cooperates with the reverse slope of the convex portion of the slider to push the convex portion of the slider inward, causing the slider to move inward along the first sliding groove of the second push plate, compressing and deforming the spring portion. At the same time, the slider is decoupled from the hook portion, and the lifting drive mechanism no longer provides upward power for the second push plate and the second push pressure plate. The first push rod rises to the set height. At the same time, to prevent the second push plate and the second push pressure plate from continuing to rise due to the action of inertia force, causing the first push rod to be excessively displaced, the displacement of the second push plate and the second push pressure plate is further limited by the provided limit posts; at the same time, the drive axis continues to drive the first push plate and the first push pressure plate to rise, and then drives the second push rod to rise; in the third step, when the second push rod rises to a certain distance, the arc transition portion of the second push rod will cooperate with the guide groove of the guide block provided on the support plate frame, causing the second push rod to deviate from the original movement track and move inward. Then the second push rod continues to rise to the predetermined position. Through this action, the second side mold can be shrunk inside the casting product, enabling the casting die core to be completely separated from the product; in the fourth step, the product is clamped and taken out, the lifting drive mechanism drives the lifting assembly to reset, the lifting portion moves back to the original processing station, the first push rod and the second push rod are reset, driving the die core to reset; the slider is reset under the action of the spring portion, and the hook portion is re-hooked with the slider for the next repeated processing.

[0028] In the present invention, uniquely, after the second push rod rises to a certain distance, the arc transition part of the second push rod will cooperate with the guide groove of the guide block arranged on the pallet frame, so that the second side mold can shrink inside the cast product, causing the second push rod to deviate from the original movement trajectory and move inward, and then the second push rod continues to rise to a predetermined position, so that the casting core is completely separated from the product.

[0029] Furthermore, the first transverse movement assembly includes a first fixing part, a first connecting part connected in sequence. The first connecting part is connected to the first half mold, and one side of the first fixing part is connected to the first driving mechanism.

[0031] In this application, the first driving mechanism and the second driving mechanism respectively drive the axial movement of the first half mold and the second half mold to realize the opening and closing connection between the first half mold and the second half mold, so as to obtain the mold cavity required for production.

[0032] Furthermore, the first half mold includes a first mold cavity, a first feeding cavity, and a second mold cavity arranged in sequence. The structure of the second half mold is symmetrically arranged in cooperation with the structure of the first half mold. Specifically, the second half mold includes a third mold cavity, a second feeding cavity, and a fourth mold cavity arranged in sequence. The structure of the third mold cavity is the same as that of the second mold cavity, the structure of the fourth mold cavity is the same as that of the first mold cavity, the first mold cavity and the third mold cavity cooperate to form a first forming mold cavity, the second mold cavity and the fourth mold cavity cooperate to form a second forming mold cavity, the first feeding cavity and the second feeding cavity cooperate to form a feeding channel, and the first forming mold cavity and the second forming mold cavity are respectively communicated with the feeding channel. In this application, when the first half mold and the second half mold are closed, a first forming mold cavity, a second forming mold cavity, and a feeding channel can be respectively formed. By pouring molten metal into the feeding channel, the molten metal will flow into the first forming mold cavity and the second forming mold cavity respectively and fill them under the action of gravity. After waiting for the molten metal to condense and solidify, the first half mold and the second half mold are respectively withdrawn to obtain the product. Particularly, heat dissipation channels are respectively arranged on the upper parts of the first forming mold cavity and the second forming mold cavity.

[0033] By providing the first forming mold cavity and the second forming mold cavity, the present invention can realize continuous automatic casting of two metal T-shaped connectors at the same time, greatly improving the production efficiency.

The connecting portion is provided with a groove. The limiting member is disposed at one end of the groove and connected to the fixing member. A side die core is provided on one side of the fixing member. The connecting portion is connected to a third driving mechanism. The third driving mechanism includes a driving shaft. The driving rod is disposed in the groove and connected to the side die core. The limiting member is cooperatively arranged with one end of the driving shaft. Through the arrangement of the limiting member, the driving shaft can be effectively prevented from excessive displacement, so that the side die core deviates from the processing position, affecting the internal shape of the product and avoiding the generation of defective products. Through the third driving mechanism, the driving shaft moves back and forth along the groove of the connecting portion, realizing the feeding and retraction of the side die core, thereby realizing the lateral core-pulling movement.

[0035] Particularly, the structure of the fourth lateral translation component is the same as that of the third lateral translation component, and the fourth lateral translation component and the third lateral translation component are symmetrically arranged.
