Description

Technical Field

[0001] The present application relates to the technical field of automobile rear wheel cover fabric forming and pressing tooling, in particular to automobile rear wheel cover fabric forming and pressing tooling. Background Art

[0002] A car rear wheel cover is a decorative and protective accessory specially used to cover the rear wheels. It is usually made of plastic, alloy or other durable materials, with different designs and styles, which can be selected according to the owner's personal preferences and vehicle type. When making a car rear wheel cover, the softened fabric of the car rear wheel cover needs to be placed on a molding machine. The molding machine is divided into an upper part and a lower part. When the softened fabric of the car rear wheel cover is placed on the surface of the lower part of the molding machine, the cylinder is driven to press the upper part of the molding machine downward, thereby obtaining the initial shape of the car rear wheel cover.

[0003] At present, in the prior art, when a molding machine presses the softened fabric of a rear wheel cover of an automobile, since the softened fabric of the rear wheel cover of the automobile is soft in texture, it is easy to cause the softened fabric of the rear wheel cover of the automobile to be displaced under pressure during the pressing process, so that the pressed shape of the rear wheel cover of the automobile cannot meet the established requirements, and it is easy to produce defective products, which reduces the production efficiency and has certain inconveniences in use. Therefore, a molding and pressing tool for the fabric of the rear wheel cover of an automobile is proposed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present application provides a molding and pressing tool for automobile rear wheel cover fabric, which has the advantages of being easy to clamp the fabric to avoid fabric displacement affecting molding, etc., and solves the problem of the prior art that the fabric is easily displaced during the production of automobile rear wheel covers, resulting in the pressed automobile rear wheel cover shape not meeting the established requirements, and easily producing defective products.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a molding and pressing tool for automobile rear wheel cover fabric, comprising a frame, two hydraulic cylinders fixed to the top surface of the frame, an upper mold fixed to the bottom ends of the output shafts of the two hydraulic cylinders, a lower mold fixed to the inner bottom wall of the frame, and a pressing mechanism arranged on the upper mold and the lower mold for fixing the fabric;

[0006] The clamping mechanism includes two positioning strips respectively mounted on the outer peripheral walls of the upper mold and the lower mold, connecting blocks fixed on the front and rear sides of the positioning strips, a cylinder fixed on the front and rear sides of the upper mold and the lower mold and whose output shaft is fixed to the connecting blocks, a guide block fixed on the front and rear sides of the positioning strip, a guide ring fixed on the front and rear sides of the upper mold and the lower mold, and a guide rod slidably connected to the inside of the wire ring and one end of which is fixed to the guide block. The clamping mechanism also includes an auxiliary component for improving the clamping effect of the positioning strip.

[0007] By adopting the above technical scheme, when in use, the fabric used to make the rear wheel cover of the automobile is softened and then placed in the lower mold, and the hydraulic cylinder is controlled to push the upper mold downward to cooperate with the lower mold to form the fabric. Before the upper mold contacts the lower mold, the fabric can be pressed by the set clamping mechanism, thereby avoiding the displacement of the fabric when the upper mold is pressed down, resulting in the shape of the rear wheel cover of the automobile not meeting the established requirements and producing defective products. This can better guarantee production requirements, reduce waste of defective products, improve production efficiency, and be more convenient for promotion and use.

[0008] Furthermore, the auxiliary component includes a plurality of protruding teeth fixed on the bottom surface of the top positioning strip, a mounting block fixed on the front and rear sides of the bottom positioning strip, a positioning rod fixed on the top surface of the mounting block, and a rectangular bin fixed on the front surface of the lower mold.

[0009] By adopting the above technical solution, when the clamping mechanism presses the softened fabric, the convex teeth arranged by the auxiliary component can effectively improve the clamping effect, and at the same time cooperate with the positioning rod to pierce the edge of the fabric, making it less likely for the softened fabric to be displaced during extrusion molding, thereby further improving the clamping and fixing effect and improving practicality.

[0010] Furthermore, a plurality of tooth grooves are provided on the top surface of the bottom positioning bar, a movable hole is provided on the top surface of the rectangular bin for the positioning rod to pass through and be slidably connected thereto, and a through groove is provided on the back surface of the rectangular bin for the positioning bar to move.

[0011] By adopting the above technical scheme, the tooth grooves are arranged to cooperate with the convex teeth to enhance the clamping and fixing effect, and the rectangular bins, through grooves and movable holes of the social group are convenient for storing the positioning rods to avoid scratching workers during demoulding.

[0012] Furthermore, a plurality of smooth portions are disposed on opposite sides of the two positioning strips, and the plurality of smooth portions at the top are spaced apart from the plurality of convex teeth, and the plurality of smooth portions at the bottom are spaced apart from the plurality of tooth grooves.

[0013] By adopting the above technical solution, the surface of the positioning strip is not entirely convex teeth and tooth grooves, but also has a smooth and even part, which plays the role of meshing transition and avoids the situation where the convex teeth and tooth grooves cannot complete the meshing after the two positioning strips are close to each other due to the meshing parts being entirely meshing parts.

[0014] Furthermore, the convex teeth and the tooth grooves are opposite to each other in vertical direction and are matched with each other, the top end of the positioning rod is in a pointed cone shape, and the rectangular bin is used for the mounting block to slide up and down inside it.

[0015] By adopting the above technical solution, the conical setting of the positioning rod tip facilitates better piercing of the fabric to achieve a positioning effect.

[0016] Furthermore, the upper mold and the lower mold are opposite to each other in vertical direction and are matched with each other, and the positioning strip is annularly sleeved on the outer peripheral walls of the upper mold and the lower mold and is slidably connected thereto.

[0017] By adopting the above technical solution, it is convenient to push the upper mold up and down through the hydraulic cylinder to cooperate with the lower mold to complete the extrusion molding.

[0018] Furthermore, the top connection block and the bottom connection block are vertically opposite to each other, and the output shaft of the cylinder is fixed to the opposite sides of the two vertically opposite connection blocks.

[0019] By adopting the above technical solution, it is convenient to control the positioning bar to slide up and down relative to the upper mold and the lower mold through the provided cylinder.

[0020] Furthermore, the guide block at the top and the guide block at the bottom are vertically opposite to each other, and the guide rod is fixed to the opposite sides of the two vertically opposite guide blocks, and the guide ring is used for the guide rod to slide up and down inside it.

[0021] By adopting the above technical solution, the stability of the upward and downward sliding adjustment of the positioning bar can be improved by means of the guide rod, the guide block and the guide ring.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] 1. When the automobile rear wheel cover fabric forming and pressing tool is used, the fabric used to make the automobile rear wheel cover is softened and then put into the lower mold, and the hydraulic cylinder is controlled to push the upper mold downward to cooperate with the lower mold to form the fabric. Before the upper mold contacts the lower mold, the fabric can be pressed by the set pressing mechanism, thereby avoiding the displacement of the fabric when the upper mold is pressed downward, resulting in the shape of the automobile rear wheel cover not meeting the established requirements and producing defective products, which can better guarantee production requirements and reduce the waste of defective products, improve production efficiency, and be more convenient for promotion and use.

[0024] 2. The automobile rear wheel cover fabric forming and pressing tooling, when the pressing mechanism presses the softened fabric, the convex teeth arranged in the auxiliary component cooperate with the tooth grooves to effectively improve the pressing effect, and at the same time cooperate with the positioning rod to pierce the edge of the fabric, so that the softened fabric is less likely to be displaced during extrusion molding, further improving the pressing and fixing effect, and having better practicality.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0032] See also Figure 1-3 The automobile rear wheel cover fabric forming and pressing tooling in this embodiment includes a frame 1, two hydraulic cylinders 2 fixed to the top surface of the frame 1, an upper mold 3 fixed to the bottom ends of the output shafts of the two hydraulic cylinders 2, a lower mold 4 fixed to the inner bottom wall of the frame 1, and a pressing mechanism 5 for fixing the fabric arranged on the upper mold 3 and the lower mold 4. The upper mold 3 and the lower mold 4 are opposite to each other and the two are adapted to each other. When in use, the fabric used to make the automobile rear wheel cover is softened and put into the lower mold 4, and the hydraulic cylinder 2 is controlled to push the upper mold 3 downward to cooperate with the lower mold 4 to form the fabric. Before the upper mold 3 contacts the lower mold 4, the fabric can be pressed by the set pressing mechanism 5, thereby avoiding the displacement of the fabric when the upper mold 3 is pressed downward, resulting in the shape of the automobile rear wheel cover failing to meet the established requirements and producing defective products, which can better ensure production requirements and reduce waste of defective products, have better production efficiency, and are more convenient for promotion and use.

[0033] It should be noted that the control method of the present application is controlled by a controller, and the control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present application is mainly used to protect mechanical devices, so the present application will no longer explain the control method and circuit connection in detail.

[0034] See also Figure 1-3The clamping mechanism 5 includes two positioning strips 501 respectively mounted on the outer peripheral walls of the upper mold 3 and the lower mold 4, a connecting block 502 fixed to the front and rear sides of the positioning strip 501, a cylinder 503 fixed to the front and rear sides of the upper mold 3 and the lower mold 4 and whose output shaft is fixed to the connecting block 502, a guide block 504 fixed to the front and rear sides of the positioning strip 501, a guide ring 505 fixed to the front and rear sides of the upper mold 3 and the lower mold 4, and a guide rod 506 slidably connected to the inside of the guide ring 505 and one end of which is fixed to the guide block 504. When in use, it will be used to make automobiles. After the fabric of the rear wheel cover is softened, it is put into the lower mold 4, and the hydraulic cylinder 2 is started to extend to drive the upper mold 3 to move downward. When the upper mold 3 is about to fit with the lower mold 4, the cylinder 503 is started to extend, and the cylinders 503 on the upper and lower sides push the connecting blocks 502 on the upper and lower sides to move relative to each other. The connecting blocks 502 drive the upper and lower positioning strips 501 to move relative to each other, so that the two positioning strips 501 clamp the edge of the fabric to press and fix it, which facilitates the molding of the upper mold 3 and the lower mold 4. The clamping mechanism 5 also includes an auxiliary component 6 for improving the clamping effect of the positioning strip 501.

[0035] In this embodiment, the positioning bar 501 is annularly sleeved on the outer peripheral walls of the upper mold 3 and the lower mold 4 and is slidably connected thereto, the top connecting block 502 and the bottom connecting block 502 are opposite to each other in vertical direction, the output shaft of the cylinder 503 is fixed on the opposite sides of the two connecting blocks 502 opposite to each other in vertical direction, the top guide block 504 and the bottom guide block 504 are opposite to each other in vertical direction, and the guide rod 506 is fixed on the opposite sides of the two guide blocks 504 opposite to each other in vertical direction, and the guide ring 505 is used for allowing the guide rod 506 to slide up and down inside it.

[0036] See also Figure 2-5 In this embodiment, the auxiliary component 6 includes a plurality of convex teeth 601 fixed to the bottom surface of the top positioning strip 501, a mounting block 602 fixed to the front and rear sides of the bottom positioning strip 501, a positioning rod 603 fixed to the top surface of the mounting block 602, and a rectangular bin 604 fixed to the front surface of the lower mold 4. The top surface of the bottom positioning strip 501 is provided with a plurality of tooth grooves 605. The convex teeth 601 and the tooth grooves 605 are opposite to each other and are matched. The top end of the positioning rod 603 is in a pointed cone shape. When the two positioning strips 501 move relative to each other, the positioning rod 603 is in a pointed cone shape. When the top positioning bar 501 moves, the convex teeth 601 on the top positioning bar 501 will mesh with the tooth grooves 605 on the bottom positioning bar 501. The meshing can enhance the clamping effect on the softened fabric, making it difficult for the softened fabric to be displaced during extrusion molding. In order to further enhance the clamping effect, a plurality of positioning rods 603 are provided on the positioning bar 501. The ends of the positioning rods 603 are pointed, which can directly pierce the edge of the softened fabric, making it more difficult for the softened fabric to be displaced during extrusion molding.

[0037] See also Figure 2-5In this embodiment, a movable hole 606 is provided on the top surface of the rectangular bin 604 for the positioning rod 603 to pass through and be slidably connected thereto, and a through groove 607 is provided on the back surface of the rectangular bin 604 for the positioning bar 501 to move. When demolding is performed after extrusion molding, the bottom cylinder 503 drives the positioning bar 501 to move downward, and the positioning bar 501 drives the mounting block 602 and the positioning rod 603 to move downward, so that the positioning rod 603 can be stored in the interior of the rectangular bin 604, so as to prevent the sharp part of the positioning rod 603 from scratching the workers when demolding.

[0038] In this embodiment, multiple smooth portions 608 are provided on opposite sides of the two positioning strips 501, and the multiple smooth portions 608 on the top are spaced apart from the multiple convex teeth 601, and the multiple smooth portions 608 on the bottom are spaced apart from the multiple tooth grooves 605. The surface of the positioning strip 501 is not entirely convex teeth 601 and tooth grooves 605, but also has smooth smooth portions 608, which play a role in meshing transition, and avoid the situation where the convex teeth 601 and the tooth grooves 605 cannot complete the meshing after the two positioning strips 501 are close to each other due to the meshing parts being all meshing parts. The rectangular bin 604 is used for the mounting block 602 to slide up and down inside it.

[0039] The working principle of the above embodiment is:

[0040] (1) When in use, soften the fabric used to make the rear wheel cover of the car and put it into the lower mold 4, start the hydraulic cylinder 2 to extend and drive the upper mold 3 to move downward. When the upper mold 3 is about to fit with the lower mold 4, start the cylinder 503 to extend, and the cylinders 503 on the upper and lower sides push the connecting blocks 502 on the upper and lower sides to move relative to each other. The connecting blocks 502 drive the upper and lower positioning bars 501 to move relative to each other, so that the two positioning bars 501 clamp the edge of the fabric to press and fix it, which provides convenience for the molding of the upper mold 3 and the lower mold 4.

[0041] (2) When the two positioning bars 501 move relative to each other, the convex teeth 601 on the top positioning bar 501 will mesh with the tooth grooves 605 on the bottom positioning bar 501. The meshing can enhance the clamping effect on the softened fabric, making it difficult for the softened fabric to be displaced during extrusion molding. In order to further enhance the clamping effect, a plurality of positioning rods 603 are provided on the positioning bar 501. The ends of the positioning rods 603 are pointed, which can directly pierce the edges of the softened fabric, making it more difficult for the softened fabric to be displaced during extrusion molding. When demolding is performed after extrusion molding, the bottom cylinder 503 drives the positioning bar 501 to move downward, and the positioning bar 501 drives the mounting block 602 and the positioning rod 603 to move downward, so that the positioning rod 603 can be stored in the rectangular bin 604, thereby preventing the sharp part of the positioning rod 603 from scratching the workers when demolding.
