Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, a production mold for a main casing of a micro core pile comprises a movable mold 1, a fixed mold 2 and a thimble 3. The lower end face of the movable die 1 is provided with a die core 11, the upper end face of the fixed die 2 is provided with a die cavity 21, and the die cavity can be formed by matching the die core 11 with the die cavity 21 for product molding.

As shown in fig. 1 and 2, the ejector pin 3 is vertically slidably connected to the fixed mold 2, penetrates through the cavity 21, and is located at the right center of the cavity 21. When the thimble 3 is in the retracted state, the upper end surface of the thimble 3 is flush with the bottom wall of the cavity 21, so that the complete molding of the product is ensured. Simultaneously, the fixed die 2 is vertically and slidably connected with a top plate 22, the top plate 22 is pushed by a cylinder, and meanwhile, the lower end of the thimble 3 is fixed with the top plate 22.

When the main shell is produced, the brake die 1 is controlled to be close to the fixed die 2, die assembly between the movable die 1 and the fixed die 2 is realized, a die cavity is formed between the core 11 and the die cavity 21, and then molten plastic is injected into the die cavity, so that injection molding of a product is realized.

After the product is molded, the movable die 1 is controlled to be opened to realize die opening, then the top plate 22 and the ejector pins 3 are controlled by the air cylinders to move upwards, the product is ejected out by the ejector pins 3 and is in a suspended state and is positioned above the fixed die 2, and finally the product is taken down to realize the production and processing of the main shell.

As shown in fig. 3, the mold further includes a pair of rotating rods 4, a pair of clamping rods 5, and a pair of collet chucks 51. One pair of rotating rods 4 are attached to two sides of the fixed die 2, one end of each rotating rod is connected to two sides of the fixed die 2 in a rotating mode, and meanwhile the rotating rods 4 synchronously rotate.

As shown in fig. 3, a pair of holding bars 5 are horizontally rotatably connected to the other ends of the rotating bars 4 close to each other, and are used for holding products. The elastic chucks 51 are arranged at the end parts of the clamping rods 5 and are hollow and used for propping up the outer wall of the upper end of a product after deformation, so that stable clamping of the product is realized.

When the ejector pins 3 are ejected out, the servo motor is used for controlling the pair of rotating rods 4 to synchronously rotate, so that the pair of rotating rods 4 rotate from a horizontal state to a vertical state, at the moment, the pair of rotating rods 4 drive the pair of clamping rods 5 to synchronously rotate, and the elastic chucks 51 deform to clamp two sides of a product.

Then the ejector rod is controlled to retract, the rotating rod 4 is controlled to reversely rotate by the servo motor, and the rotating rod 4 is horizontally reset. Because the upper end of the product is clamped by the clamping rod 5, and the rotating rod 4 is connected with the clamping rod 5 in a rotating way, under the action of the gravity of the product, no matter how the rotating rod 4 rotates, the product can keep the initial direction, namely the product is always downward, so that the product is conveniently unloaded and transported.

As shown in fig. 3, the mould further comprises a support frame 6, a slide plate 7, a number of collecting bars 71 and a control mechanism 8. The support frame 6 is arranged in a strip shape, is positioned below the fixed die 2 and is positioned between the pair of rotating rods 4. The sliding plate 7 is disposed along the length direction of the supporting frame 6, and is horizontally slidably connected to the supporting frame 6 and located between the pair of rotating rods 4.

As shown in fig. 3 and 4, the collecting rods 71 are vertically and spaced on the sliding plate 7 and are uniformly distributed along the length direction of the sliding plate 7, the collecting rods 71 are sleeved with products, and an elastic pad 72 is arranged at the upper end of the collecting rod 71. Wherein the control mechanism 8 is used for controlling the sliding plate 7 to slide unidirectionally and intermittently, and the sliding distance of each time is the distance of one product.

As shown in fig. 3 and 4, the control mechanism 8 includes a rotation shaft 81, a gear 82, a rack 83, a ratchet 84, and a ratchet ring 85. The rotating shaft 81 is horizontally and horizontally rotatably connected to the supporting frame 6 and is positioned below the sliding plate 7. The gear 82 is provided on the rotation shaft 81 and is located directly below the sliding plate 7 in the axial direction.

As shown in fig. 3 and 4, the rack 83 is horizontally provided on the lower end surface of the slide plate 7 along the longitudinal direction of the slide plate 7 and is engaged with the gear 82, so that the slide plate 7 can be controlled to move synchronously when the rotation shaft 81 rotates.

As shown in fig. 3 and 4, the ratchet 84 is disposed at an end of the rotating shaft 81, the ratchet ring 85 is sleeved on an outer wall of the ratchet 84, and when the ratchet ring 85 rotates in a normal direction, the ratchet ring 84 can be driven to rotate together, and when the ratchet ring 85 rotates in a reverse direction, the ratchet ring 85 and the ratchet 84 idle, at this time, the rotating shaft 81 is in a static state.

As shown in fig. 3 and 4, the ratchet ring further comprises a driving mechanism 9, wherein the driving mechanism 9 is used for driving the ratchet ring 85 to intermittently and reciprocally rotate. The driving mechanism 9 includes a driving plate 91, a weight 92, a driving lever 93, and a stopper plate 94.

As shown in fig. 3 and 4, the driving plate 91 is disposed laterally on the ratchet ring 85 and is disposed along the length direction of the sliding plate 7. The balancing weight 92 is disposed on the lower end surface of one end of the driving plate 91, the limiting plate 94 is disposed on the supporting frame 6 and is used for abutting against the balancing weight 92, and the balancing weight 92 is provided with a magnet 95 for adsorbing the limiting plate 94.

As shown in fig. 3 and 4, the driving rod 93 is vertically disposed on the side wall of the movable mold 1 and is used for pressing one end of the driving plate 91 away from the balancing weight 92, and when the movable mold 1 is closed, one end of the driving plate 91 away from the balancing weight 92 is located at the lowest point position, and the balancing weight 92 is located at the highest point position.

When the rotating rod 4 drives the product to overturn downwards, the product is automatically sleeved on the collecting rod 71, so that the fixed-point storage and placement of the product are realized. And then the brake die 1 is controlled to be clamped, when the movable die 1 is clamped, the movable die 1 drives the driving rod 93 to synchronously move, and at the moment, the driving rod 93 abuts against the driving plate 91 and controls the driving plate 91 to turn over.

When the driving plate 91 is turned over, the driving plate 91 drives the ratchet ring 85 to rotate, forward rotation control of the ratchet ring 85 is achieved, at the moment, the ratchet ring 85 and the ratchet 84 are clamped with each other, the control rotating shaft 81 and the gear 82 rotate normally, and at the moment, the gear 82 controls the rack 83 and the sliding plate 7 to slide synchronously. At this time, the sliding plate 7 slides forward by one unit, so that the clamping rod 5 is separated from the product, and the independent storage of the product is completed.

When the product is processed and the movable die 1 is opened, the movable die 1 drives the driving rod 93, and at this time, the driving rod 93 gradually breaks away from the driving plate 91. At the same time, the driving plate 91 is controlled to automatically reversely move and reset under the auxiliary action of the balancing weight 92.

Meanwhile, since the ratchet wheel 84 and the ratchet ring 85 can only move in one direction, the ratchet wheel 84 and the ratchet ring 85 are idle at this time, that is, the rotation shaft 81 and the slide plate 7 are both in a stationary state, thereby realizing intermittent one-way slip control of the slide plate 7.

In turn, when the movable die 1 is opened, the rotating rod 4 works to take down the molded product and automatically sleeves the collecting rod 71 along with the rotation of the rotating rod 4. Subsequently, the movable mold 1 is closed, and the slide plate 7 is controlled to slide forward, so that the next collecting lever 71 is moved forward, and the next product is stored.

As shown in fig. 3 and 4, a cooling fan cover 61 through which the slide plate 7 is inserted is provided at the front end of the support frame 6. Therefore, when the product is taken down and transported, the product enters the cooling fan cover 61 for cooling, so that the synchronous processing, taking-off and cooling of the product are realized, and the production efficiency of the product is ensured.

As shown in fig. 5, the holding lever 5 includes a first lever body 52, a second lever body 53, a shutter 54, and a spring 55. The first rod 52 is horizontally slidably connected to the rotating rod 4, the second rod 53 is horizontally rotatably connected to one end of the first rod 52, and the elastic clamping head 51 is located at one end of the second rod 53 facing away from the first rod 52.

As shown in fig. 5, the baffle 54 is disposed at one end of the first rod 52 facing away from the second rod 53, and the spring 55 is sleeved on the outer wall of the first rod 52 and located between the rotating rod 4 and the baffle 54, so as to realize automatic reset control after the first rod 52 slides.

Through setting up clamping lever 5 into the two parts of first body of rod 52 and second body of rod 53 to make whole clamping lever 5 can slide on dwang 4, make the distance between the clamping lever 5 can change voluntarily, and can reset voluntarily, so this kind of structure can be adapted to the production of different specification model products, improves the practicality.
