[0014] A method for producing a glass fiber reinforced nylon material for blow molding, which uses the above-mentioned production equipment for glass fiber reinforced nylon material for blow molding, and the production method for glass fiber reinforced nylon material for blow molding comprises the following steps:

[0015] Step 1: The raw materials are mixed evenly by a mixing device and then put into an extruder for extrusion;

[0016] Step 2: The extrusion end of the extruder is connected to the feed end of the preforming injection mold. At this time, the electric lifting push rod is extended to allow the gas injection head to enter the interior of the preforming injection mold, and the bottom of the neck mold is fitted with the top of the preforming injection mold for sealing. There is a gap between the gas injection head and the inner wall of the preforming injection mold so that the molten raw material can be coated on the outer wall of the gas injection head;

[0017] Step 3: The gas injection head carries the raw material attached to its outer wall and rises away from the position where the preformed injection mold is located, and the driving motor drives the support plate to rotate so that the gas injection head with the raw material attached to the surface rotates to the top of the blow mold assembly;

[0018] Step 4: The gas injection head carries the raw material downward, and the hydraulic push rod extends to make the mold bodies approach each other and close together, so that the gas injection head carries the raw material inside the mold body. At this time, the gas supply hose inputs gas to the gas injection head, causing the raw material to expand until it contacts the inner wall of the mold body for shaping;

[0019] Step 5: After the product is solidified and shaped, the mold body is separated to expose the product. At this time, the gas injection head carries the product and rotates to the unloading place. At this time, the electric telescopic rod contracts to make the gas injection head and the mold support ball rise. When the mold support ball rises, it will support the arc plate outward to separate the neck mold from each other, thereby separating the contact between the product neck and the inner wall of the neck mold;

[0020] Step six: The electric telescopic rod continues to contract so that the mold support ball enters the oil tube to push the piston up, so that the return spring and the oil are compressed, and the oil is pressed into the cavity in the inner walls on both sides of the oil tube to push the telescopic rod body to extend, so that the telescopic rod body extends downward to push the demolding sleeve to slide down along the outer wall of the gas injection head, so as to push the product away from the outer wall of the gas injection head and fall to the unloading place to complete the unloading, and then repeat the operations of steps two to six.

[0022] PA6 nylon or PA66 nylon: 600-700 parts, glass fiber 200-400 parts, antioxidant 1-3 parts, lubricant 9-10 parts, anti-ultraviolet agent 4-5 parts.

[0023] The present invention provides a glass fiber reinforced nylon material for blow molding and a production device and method thereof, which have the following beneficial effects:

[0024] 1. The glass fiber reinforced nylon material for blow molding and the production equipment and method thereof utilize the electric telescopic rod to shrink to make the mold support ball rise. During the rising process of the mold support ball, the neck mold is first separated so that the neck of the product is separated from the inside of the neck mold. Then, as the mold support ball continues to rise, the piston is pushed up so that the oil is pressed into the cavity in the inner wall of the oil pipe on both sides to push the telescopic rod body to extend, so that the telescopic rod body extends downward to push the demoulding sleeve to slide down along the outer wall of the gas injection head, so as to push the product to separate from the outer wall of the gas injection head and fall to the unloading place to complete the unloading.

[0025] 2. In the glass fiber reinforced nylon material for blow molding and the production equipment and method thereof, the demoulding sleeve is arranged on the outside of the rod body of the electric telescopic rod, and the two are not fixedly connected, so that when the electric telescopic rod is initially contracted, the demoulding sleeve is kept in the same position under the elastic action of the return spring, so as to avoid the demoulding sleeve from being lifted up at the beginning as the electric telescopic rod is contracted, so as to avoid the movement interference caused by the simultaneous separation of the neck mold and the sliding down of the demoulding sleeve.

DETAILED DESCRIPTION

[0033] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0034] like Figure 1-Figure 6As shown, the present invention provides a technical solution: a production equipment for glass fiber reinforced nylon material for blow molding, comprising a preforming injection mold 1 and a blow molding component 2, wherein the blow molding component 2 is arranged above the preforming injection mold 1, and the blow molding component 2 comprises a shell 201, an oil pipe 202, a return spring 203, a piston 204, an electric telescopic rod 205, an injection head 206, an air supply hose 207, a spring outer tube 208, a movable rod 209, a neck mold 210, an arc plate 211, a mold support ball 212, a telescopic rod body 213 and a demolding sleeve 214, an oil pipe 202 is fixed to the top of the inner wall of the shell 201, and a return spring 203 is arranged inside the oil pipe 202, a piston 204 is fixed to the bottom of the return spring 203, an electric telescopic rod 205 is fixed to the top of the shell 201, and an injection head 206 is fixed to the bottom end of the electric telescopic rod 205, and the surface of the injection head 206 is connected to the air supply hose 207, spring outer tubes 208 are fixed on both sides of the cladding 201, and the interior of the spring outer tube 208 is connected to a movable rod 209 through a spring, a neck mold 210 is fixed to the outer end of the movable rod 209, and an arc plate 211 is fixed to the inner end of the movable rod 209, a mold ball 212 is fixed to the lower outer wall of the electric telescopic rod 205, and a telescopic rod body 213 is penetrated on both sides of the bottom of the oil pipe 202, and a demoulding sleeve is connected to the bottom of the telescopic rod body 213 214, the lower part of the electric telescopic rod 205 passes through the interior of the oil pipe 202, and the lower outer wall of the electric telescopic rod 205 is slidably connected with the piston 204, the bottom opening diameter of the oil pipe 202 is larger than the outer diameter of the mold ball 212, and the arc plates 211 are symmetrically distributed about the central axis of the mold ball 212, and the demoulding sleeve 214 is sleeved on the upper part of the outer wall of the gas injection head 206, and there is a distance between the outer wall of the gas injection head 206 and the inner wall of the neck mold 210;

[0035] The specific operation is as follows: the extrusion end of the extruder is connected to the feed end of the preforming injection mold 1, and the electric lifting push rod 3 is extended to allow the gas injection head 206 to enter the interior of the preforming injection mold 1, and the bottom of the neck mold 210 is fitted with the top of the preforming injection mold 1 for sealing. There is a gap between the gas injection head 206 and the inner wall of the preforming injection mold 1 so that the molten raw material can be covered on the outer wall of the gas injection head 206. At this time, the neck mold 210 clamps the top of the raw material. Since the inner wall of the neck mold 210 is a concave structure, it is convenient to clamp the raw material to prevent the raw material on the surface of the gas injection head 206 from accidentally falling off during the rotation process.

[0036] When the glass fiber reinforced nylon material of the present invention is used for product blow molding, the raw material in the pre-molding stage is attached to the outer wall of the gas injection head 206, and the top of the material is in contact with the bottom of the demolding sleeve 214. The bottom of the demolding sleeve 214 can be pre-oiled to facilitate later demolding, and the top of the raw material outer wall is also in contact with the inner wall of the neck mold 210, and the neck mold 210 is closed by the spring inside the spring outer tube 208.

[0037] After the product is solidified and shaped, the gas injection head 206 carries the product to the unloading place, and at this time, the electric telescopic rod 205 contracts to make the gas injection head 206 and the mold support ball 212 rise. When the mold support ball 212 rises, it will support the arc plate 211 to separate the neck mold 210 from each other, thereby separating the contact between the neck of the product and the inner wall of the neck mold 210, so as to avoid the demoulding sleeve 214 descending to push the product to unload and being blocked by the closed neck mold 210 to cause movement interference. 05 Continue to contract so that the mold support ball 212 enters the oil pipe 202 to push the piston 204 up, so that the return spring 203 and the oil are compressed, and the oil is pressed into the cavity in the inner wall of both sides of the oil pipe 202 to push the telescopic rod 213 to extend, so that the telescopic rod 213 extends downward to push the demoulding sleeve 214 to slide down along the outer wall of the gas injection head 206, so as to push the product to break away from the outer wall of the gas injection head 206 and fall to the unloading place to complete the unloading, and then repeat the above operation to realize continuous operation;

[0038] Based on the above description, the present invention utilizes the electric telescopic rod 205 to contract to make the mold support ball 212 rise. During the rising process of the mold support ball 212, the neck mold 210 is first separated so that the neck of the product is separated from the inside of the neck mold 210. Then, as the mold support ball 212 continues to rise, the piston 204 is pushed up so that the oil is pressed into the cavity in the inner walls of both sides of the oil pipe 202 to push the telescopic rod body 213 to extend, so that the telescopic rod body 213 extends downward to push the demolding sleeve 214 to slide down along the outer wall of the gas injection head 206, so as to push the product to separate from the outer wall of the gas injection head 206 and fall to the unloading place to complete the unloading;

[0039] Secondly, the demolding sleeve 214 is sleeved on the outside of the rod body of the electric telescopic rod 205, and the two are not fixedly connected, so that when the electric telescopic rod 205 is initially contracted, the demolding sleeve 214 maintains an unchanged position under the elastic action of the return spring 203, so as to avoid the demolding sleeve 214 being lifted up at the beginning as the electric telescopic rod 205 contracts, so as to avoid the separation operation of the neck mold 210 and the sliding down of the demolding sleeve 214 being carried out simultaneously to cause motion interference.

[0040] like Figure 1-Figure 6 As shown, an electric lifting push rod 3 is fixed to the outer side of the package shell 201, and a support plate 4 is fixed to the outer wall of the electric lifting push rod 3, a driving motor 5 is arranged in the middle of the support plate 4, and a blow mold assembly 6 is arranged below one end of the support plate 4, and the blow mold assembly 6 includes a hydraulic push rod 601 and a mold body 602, and the mold body 602 is fixed to the end of the hydraulic push rod 601, and the top structure of the mold body 602 is adapted to the bottom structure of the neck mold 210, and the bottom of the neck mold 210 is adapted to the top of the preform injection mold 1;

[0041] The specific operation is as follows: the raw materials used for the glass fiber reinforced nylon material of the present invention are mixed evenly by a mixing device and then put into an extruder for extrusion. The extrusion end of the extruder is connected with the feeding end of the preforming injection mold 1. After the gas injection head 206 attaches a sufficient amount of raw materials to the inside of the preforming injection mold 1, the gas injection head 206 carries the raw materials attached to its outer wall and rises away from the position of the preforming injection mold 1, and drives the support plate 4 to rotate by the driving motor 5 so that the gas injection head 206 with the raw materials attached to the surface rotates to the top of the blow mold assembly 6, and the gas injection head 206 carries the raw materials down, and the hydraulic push rod 601 extends so that the mold bodies 602 are close to each other and closed, so that the gas injection head 206 carries the raw materials and is located inside the mold body 602. At this time, the gas supply hose 207 inputs gas to the gas injection head 206, so that the raw materials expand until they contact the inner wall of the mold body 602 for shaping. After the product is solidified and shaped, the mold body 602 is separated to expose the product. At this time, the gas injection head 206 carries the product and rotates to the unloading place to unload the product.

[0043] Step 1: The raw materials are mixed evenly by a mixing device and then put into an extruder for extrusion;

[0044] Step 2: The extrusion end of the extruder is connected to the feeding end of the preforming injection mold 1. At this time, the electric lifting push rod 3 is extended to allow the gas injection head 206 to enter the interior of the preforming injection mold 1, and the bottom of the neck mold 210 is fitted with the top of the preforming injection mold 1 to be sealed. There is a gap between the gas injection head 206 and the inner wall of the preforming injection mold 1 so that the molten raw material can be coated on the outer wall of the gas injection head 206;

[0045] Step 3: The gas injection head 206 carries the raw material attached to its outer wall and rises away from the position of the preform injection mold 1, and drives the support plate 4 to rotate through the driving motor 5 so that the gas injection head 206 with the raw material attached to the surface rotates to the top of the blow mold assembly 6;

[0046] Step 4: The gas injection head 206 carries the raw material downward, and the hydraulic push rod 601 extends to make the mold body 602 approach each other and close together, so that the gas injection head 206 carries the raw material inside the mold body 602. At this time, the gas hose 207 inputs gas to the gas injection head 206, so that the raw material expands until it contacts the inner wall of the mold body 602 for shaping;

[0047] Step 5: After the product is solidified and shaped, the mold body 602 is separated to expose the product. At this time, the gas injection head 206 carries the product and rotates to the unloading place. At this time, the electric telescopic rod 205 contracts to make the gas injection head 206 and the mold support ball 212 rise. When the mold support ball 212 rises, it will support the arc plate 211 to separate the neck mold 210 from each other, thereby separating the contact between the neck of the product and the inner wall of the neck mold 210;

[0048] Step six: The electric telescopic rod 205 continues to contract so that the mold support ball 212 enters the oil tube 202 to push the piston 204 to rise, so that the return spring 203 and the oil are compressed, and the oil is pressed into the cavity in the inner walls on both sides of the oil tube 202 to push the telescopic rod body 213 to extend, so that the telescopic rod body 213 extends downward to push the demolding sleeve 214 to slide down along the outer wall of the gas injection head 206, so as to push the product away from the outer wall of the gas injection head 206 and fall to the unloading place to complete the unloading, and then repeat the operations of steps two to six.
