Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

Referring to Figures 1 to 9, the present invention provides a technical solution: an insulator vulcanization molding equipment, including a clay feeding part 1, a hot press forming part 2 and a loading and unloading transmission part 4;

The hot press forming part 2 includes an upper mold 201, a lower mold 202 and a power mechanism that drives the two to separate films. The upper mold 201 and the lower mold 202 both have integrated heating mechanisms;

The loading and unloading transmission part 4 includes two sets of supporting brackets 401 distributed on both sides of the hot press forming part 2. The supporting brackets 401 can slide horizontally and longitudinally, and can rise and fall in the vertical direction;

The clay feeding part 1 is arranged at the upper side of the upstream end of the hot press forming part 2, and includes a shaping roller 103 that is opposite and used for feeding clay, and a feeding telescopic rod 101 that is arranged on the downstream side and telescopes along the clay feeding direction. ; The free end of the feeding telescopic rod 101 is vertically provided with an optical axis 104; it also includes a cement fixed pressure block 404 that can fix the front end of the glue to the upstream end of the lower mold 202, and a power mechanism that drives the glue fixed pressure block 404 to open and close;

When the feeding telescopic rod 101 is at the minimum stroke, after the clay crosses the shaping roller 103 and the optical axis 104, it can freely fall into the fixed area between the clay fixed pressing block 404 and the lower mold 202;

When the upper mold 201 and the lower mold 202 are in a separated state, the optical axis 104 can be driven by the feeding telescopic rod 101 to traverse the middle area of the upper mold 201 and the lower mold 202 .

When designing, the feeding telescopic rod 101 is arranged obliquely, so that when the feeding telescopic rod 101 reaches the maximum stroke, the optical axis 104 traverses the gap between the upper mold 201 and the lower mold 202, and the horizontal height of the optical axis 104 at this time is equal to The upper surface of the lower mold 202 is flush with, or slightly lower than, the upper surface of the lower mold 202, so that the lower layer of glue can fit more docilely to the surface of the lower mold 202, and the upper layer of glue has a common tension between the optical axis 104 and the shaping roller 103. At this time, the upper layer of clay and the lower layer of clay are connected at the downstream end, and there is a large gap between the two, which is convenient for the supporting bracket 401 to place the mandrel, and the clay will not affect the placement of the mandrel. cause interference.

Referring to Figure 8, after the upper mold 201 and the lower mold 202 are closed, there are several sets of mold cavities that can independently accommodate workpieces, and the large and small umbrella mold cavities of the adjacent two sets of mold cavities are staggeredly arranged; the end of the mold cavity and the insulator terminal The cross section at the corresponding position is elliptical;

When designing the mold, the two pieces of insulators are arranged staggeredly so that the large and small umbrella pieces of the two adjacent pieces of insulators are in the same plane. That is, when the upper mold 201 and the lower mold 202 are closed, when the clay flows under pressure, most of the In order to flow longitudinally and reduce the lateral flow of clay, the clay can fill the mold cavity more quickly, ensure the uniformity of filling at each position in the mold cavity, and reduce the waste of clay.

Referring to Figure 5, it also includes a mandrel arrangement part 3, active baffles 301 and passive baffles 302 distributed on both sides of the hot press forming part 2, and a driving telescopic rod 303 that drives the two to move transversely; the active baffle 301 and the passive baffle 303 The horizontal middle surface of the baffle 302 is coplanar with the joint surface of the upper mold 201 and the lower mold 202;

The active baffle 301 is provided with a piston cylinder 3011 connected to a power source and capable of transverse movement. The passive baffle 302 is provided with a floating plate 3021 installed through an elastic member 3022 and capable of transverse movement. The piston cylinder 3011 and the floating plate 3021 One-to-one correspondence with both ends of the workpiece in the mold cavity;

The outer end surfaces of the piston cylinder 3011 and the floating plate 3021 are both provided with concave spherical bowl surfaces or tapered holes.

In order to match the layout of the insulators in the mold cavity, the active baffle 301 and the passive baffle 302 are used to first align the two ends of the core rod, and then through the action of the piston cylinder 3011 and the floating cooperation with the floating plate 3021, two adjacent groups are realized The axial stroke difference of the mandrel meets the final consistency requirements of the workpiece.

At the same time, the end faces of the piston cylinder 3011 and the floating plate 3021 adopt a concave bowl structure or a tapered hole structure. By consistent setting of the axis of the two and the axis of the mold cavity, the mandrel is in contact with the mold during the layout process. The relative position of the axes in the mold cavity is fixed to ensure that after the upper mold 201 and the lower mold 202 are closed, the axis of the mandrel can overlap with the axis of the mold cavity, that is, the thickness of the clay coating on the outer circumference of the mandrel is consistent, thus reducing the uneven deformation caused by temperature difference. crack problem.

Referring to Figure 7, the loading and unloading transmission part 4 also includes a side slide block 403. The side slide block 403 and the lower mold 202 extend horizontally and longitudinally and are relatively slidably installed. A lifting device is arranged vertically between the supporting bracket 401 and the side slide block 403. Telescopic rod 402;

By lifting and lowering the telescopic rod 402, the supporting bracket 401 can move up and down to meet the requirements of mandrel arrangement and demoulding of the workpiece after vulcanization and molding.

The first half of the supporting bracket 401 is provided with a clamp for fixing the end of the insulator, and the second half is provided with an arc-shaped groove for supporting the insulator;

The first half of the support bracket is the loading section 4012, which uses a clamp that matches the insulator terminal to ensure that the core rod will not rotate when it is arranged, thereby ensuring that during the vulcanization process, the thickness of the clay wrapped around the core rod is uniform, and the second half For the discharge section 4011, an arc-shaped groove is used to facilitate end support and increase the stress-bearing area of the insulator end during demoulding;

At the same time, during the design, in order to meet the flexibility of the production line and adapt to the production needs of insulators with different terminal styles, the support bracket 401 integrates a detachable snap-in plate 4013. The snap-in plate 4013 is directly fixedly connected to the lifting telescopic rod 402. When replacing production products, the original supporting bracket 401 can be directly replaced with the supporting bracket 401 adapted to the new product, and the production line replacement can be quickly completed.

A bottom platform 204 is fixedly provided below the lower mold 202. Horizontal longitudinal slide rails are provided on both sides of the bottom platform 204, with a built-in drive motor; the side slide blocks 403 are slidably installed with the slide rails, and have a built-in gear that meshes with the shaft end gear of the drive motor. rack.

Referring to Figure 4, the optical axis 104 is rotated externally with a sleeve 105;

When laying the cement, the direction of the cement changes after bypassing the optical axis 104. There is relative movement between the cement and the optical axis 104. By adding the sleeve 105, the friction between the cement and the optical axis 104 can be reduced, so that the cement can The optical axis 104 is smoothly bypassed, thereby reducing the stretching and deformation of the clay due to the optical axis 104 being bypassed.

Referring to Figure 3, the hot press forming part 2 also includes a mold-parting telescopic rod 203 that drives the upper mold 201 to move; the mold-parting telescopic rod 203 includes a front telescopic rod 2032 and a rear telescopic rod 2031 that are vertically arranged at the upstream and downstream ends of the upper mold 201. The lower ends of the front telescopic rod 2032 and the rear telescopic rod 2031 are provided with a hard contact block and a limit sleeve 2034. A spring 2035 is connected along the axis between the hard contact block and the limit sleeve 2034. The limit sleeve 2034 and the upper mold 201 Fixed connection;

When the mold is closed, the hard contact block directly contacts the upper mold 201 to guide force. When the mold is separated, the hard contact block is separated from the upper mold 201. The front telescopic rod 2032 and the rear telescopic rod 2031 guide force to the upper mold 201 through the spring 2035.

The lower mold 202 is used for fixation, and the upper mold 201 is designed to be straight up and down. The structure is simple and easy to design and assemble;

At the same time, a flexible connection is used between the mold-parting telescopic rod 203 and the upper mold 201. When the mold is closed, there is a rigid contact between them, which can quickly transmit the force to ensure the mold-closing pressure. When the mold is separated, the spring 2035 is used to transmit the force, that is, the force is transmitted during mold closing. When the upper mold 201 is molded, the tensile force received by the upper mold 201 is not a sudden change force, but a linear growth force. When the upper mold 201 and the lower mold 202 are separated, the force of the spring 2035 changes suddenly, and the upper mold 201 will contact the hard contact block. There is a rigid impact, which causes the upper mold 201 to vibrate. If an insulator is adhered to the upper mold 201, the vibration can promote the detachment of the insulator.

Referring to Figure 4, the hot press forming part 2 also includes a mold-parting telescopic rod 203 that drives the upper mold 201 to move; the mold-parting telescopic rod 203 includes a front telescopic rod 2032 and a rear telescopic rod 2031 that are vertically arranged at the upstream and downstream ends of the upper mold 201; The front telescopic rod 2032 and the rear telescopic rod 2031 are both hinged with the upper mold 201; the top of the rear telescopic rod 2031 is vertically fixed, and the middle section of the front telescopic rod 2032 is hinged with a diagonal telescopic rod 2033. The front telescopic rod 2032 and the diagonal telescopic rod 2033 are hinged. The tops of 2033 are hinged and fixed;

When the mold is separated, the upstream end distance between the upper mold 201 and the lower mold 202 is larger than the downstream end;

The bottom of the mold-parting telescopic rod 203 is hinged, and a diagonal telescopic rod 2033 is added at the same time, so that the upper mold 201 can be tilted during mold-parting, that is, the upstream opening is larger than the downstream opening, thereby facilitating the installation and arrangement of the clay feeding part 1. The feeding telescopic rod 101 carries the clay and enters between the upper mold 201 and the lower mold 202.

Referring to Figure 9, the shaping roller 103 includes a lower roller 1032 with a smooth circumferential surface, and an upper roller 1031 with an annular groove on the circumferential surface;

During the production and transportation process, the clay is in the form of a continuous long plane with uniform thickness, which is transported on the guide plate 102, while the shape of the insulator is a columnar body with large and small umbrellas arranged at intervals, so it is required at different locations. The amount of wrapped clay is different. After the mold is closed, due to the high temperature of the mold itself, the clay will harden and the fluidity will decrease. Therefore, an upper roller 1031 with an annular groove and a cylindrical lower roller 1032 are used to process the clay. Pre-shaping increases the thickness of the clay used to produce the umbrella blades, while reducing the thickness of the clay at other locations, thereby reducing the flow of clay after mold closing and meeting the need for the clay to wrap the mandrel.

When using:

First, with the help of manual or other loading mechanisms, several groups of mandrel rods with terminals are arranged in the clamp of the front half of the supporting bracket 401. After the previous group of vulcanization is completed, the parting telescopic rod 203 drives the upper mold 201 to move up the parting mold. ;

At this time, the lifting telescopic rod 402 drives the supporting bracket 401 to rise to demould the vulcanized insulator. The feeding telescopic rod 101 retracts from the maximum stroke to the shortest stroke, and at the same time, the shaping roller 103 rotates to drive the glue to feed, and the glue After bypassing the optical axis 104, it freely droops to the area between the cement fixed pressing block 404 and the lower mold 202. The pressing block drives the telescopic rod 405 to move, so that the cement fixed pressing block 404 fixes the end of the clay and the lower mold 202. At this time , the supporting bracket 401 and the feeding telescopic rod 101 perform longitudinal movements synchronously to realize the unloading of the vulcanized insulator, the laying of clay and the arrangement of the mandrel rods. After completing the arrangement of the mandrel rods, the supporting bracket 401 moves downward, and the subsequent equipment alignment After the insulator is unloaded, the supporting bracket 401 is reset;

Then, the active baffle 301 and the passive baffle 302 in the core rod sorting part 3 move to the designated position under the action of the driving telescopic rod 303. The distance between them is consistent with the length of the insulator, so that the two ends of the core rod are aligned, and then the distance is The piston cylinder 3011 moves to make the core rods staggered. After adjustment, the mold is closed. After heating and stabilizing the pressure, the mold is opened;

During the vulcanization production process, by adjusting the clay formula, the adhesion of the vulcanized clay to the mold can be effectively reduced. That is, during demoulding, most of the insulators remain in the lower mold 202. In this case, the mold is closed during mold closing. Finally, the mandrel organizing part 3 is directly separated from the mandrel to avoid interference with the subsequent movement of the supporting bracket 401;

For serious glue adhesion, after the mold is opened, there is a problem that the insulator is still adhered to the upper mold 201. At this time, after the mold is closed, the mandrel finishing part 3 does not detach, and it acts as a limiter for the insulator when the mold is opened. The insulator acts to cause it to separate from the upper mold 201, and then, under the action of the supporting bracket 401 rising, the insulator is driven to separate from the lower mold 202.

Repeat the above steps to produce the next round of insulators.

Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art will understand that various changes, modifications, and substitutions can be made to these embodiments without departing from the principles and spirit of the invention. and modifications, the scope of the invention is defined by the appended claims and their equivalents.
