Description

Technical Field

[0001] The utility model belongs to the technical field of jigs and relates to a tooling jig for batch transportation of bolts. Background Art

[0002] Bolts are common fasteners in today's life and are widely used in various industries. For some specific machines, the requirements for bolts are also different, such as size requirements, shock absorption requirements, etc. For bolts with shock absorption effects, generally, the bolts need to be processed twice. Simply put, after the bolts are manufactured, rubber is injected into the heads of the bolts through a special injection mold, so that a buffer pad is formed on the heads of the bolts.

[0003] For this work, in the prior art, it is often completed manually. Simply put, it is necessary for workers to put a large number of bolts into the cavities of the mold. However, this operation step is not as simple as imagined. To meet the injection requirements, workers need to place the bolts with their heads facing down and the rod parts facing up when placing the bolts. Therefore, the whole process requires workers to hold the rod parts of the bolts by hand and place them with their heads facing down, which greatly affects the manufacturing efficiency. Secondly, the injection mold often has a relatively high residual temperature, and using the above-mentioned material loading and unloading method is also likely to cause scalding accidents. Summary of the Invention

[0004] The purpose of the utility model is to address the above problems existing in the prior art and propose a tooling jig for batch transportation of bolts. The technical problem to be solved by the utility model is: how to improve manufacturing efficiency and safety.

[0005] The purpose of the utility model can be achieved by the following technical solutions: A tooling jig for batch transportation of bolts, including a holding member, characterized in that the holding member is strip-shaped, a plurality of insertion holes are formed in the outer wall of the holding member along the length direction, the plurality of insertion holes are arranged at intervals along the length direction of the holding member, and a magnet is fixed in each insertion hole.

[0006] The working principle of the tooling fixture for batch delivery of bolts is as follows: under the premise that injection molding work has been carried out in the injection mold, the worker can load the bolts to be injected into the socket in sequence in advance, and the rods of the bolts to be injected are magnetically adsorbed by the magnets provided in the socket, so that several bolts to be injected can be clamped at one time through the holding piece, and the setting of the magnets can ensure the clamping stability of each holding piece for each bolt to be injected. On this basis, after the previous batch of bolts to be injected have been completed and demolded by the worker in the mold, the worker can lift the holding piece to transfer several bolts to be injected together, so as to realize the whole delivery of the next batch of bolts to be injected. The body is placed in the cavity of the injection mold, and a specific method is used to enable this batch of bolts to be injected to overcome the magnetic force of the magnet and be positioned in the cavity (for example, each bolt is clamped in the cavity in a clip-on manner, and when the user continuously lifts the gripping piece with force, each bolt overcomes the magnetic force of the magnet), thereby quickly completing the loading work. After the mold is closed, the worker can clamp the next batch of bolts to be injected on the gripping piece again in the above-mentioned manner, thereby ensuring that the injection molding work is more orderly and the efficiency of the bolt production and processing is guaranteed. In addition, during the entire material filling work, due to the presence of the gripping piece, it can also avoid contact between the worker and the mold, effectively avoid burn accidents, and ensure production safety.

[0007] In the above-mentioned tooling fixture for batch transportation of bolts, each of the sockets is arranged through the opposite side walls of the holding piece, and each of the sockets includes a mounting section and a filling section along the length direction. The aperture of the filling section is smaller than that of the mounting section and an abutment edge is formed between the two. The magnet is detachably connected to the mounting section and abuts against the abutment edge. As a specific solution, the sockets opened on the holding piece are all set through the side walls of the holding piece, and each socket can be divided into two parts along the length direction: an installation section and a filling section. The aperture of the filling section is smaller than the aperture of the installation section, and it is mainly used for the insertion of the rod of the injection-molded bolt, while the installation section is used for the installation of the magnet. Specifically, the connection method between the magnet and the socket installation section can be snap-fit or screw-fit, and due to the different apertures of the installation section and the filling section, a radially arranged abutment edge is formed between the two. When the magnet is installed, the magnet can eventually abut against the abutment edge, thereby ensuring the stable positioning of the magnet, and then ensuring the magnetic attraction effect of the magnet on the injection-molded bolt during operation.

[0008] In the aforementioned fixture for batch bolt delivery, the cross-sectional profile of the end of the loading section facing away from the mounting section, taken along the length of the gripping member, is arc-shaped. This ensures that the end of the loading section can adequately guide the bolt shank to be injected when it is inserted into the loading section.

[0009] In the above-mentioned fixture for batch transportation of bolts, the fixture for batch transportation of bolts further includes a rectangular bottom plate. A plurality of placement grooves are formed in the bottom plate. The plurality of placement grooves are divided into several groups. A plurality of the placement grooves in the same group are arranged at intervals along the length direction of the bottom plate, and several groups of the placement grooves are arranged at intervals along the width direction of the bottom plate. On the basis of the foregoing solution, the fixture for batch transportation of bolts further provides a bottom plate. By forming several grouped placement grooves in the bottom plate, that is to say, before clamping the bolts to be injection-molded by the holding member, when the injection mold is performing injection work, the worker can first embed several bolts to be injection-molded (heads) one by one into several placement grooves. The positions of several placement grooves in the same group correspond to the positions of the through holes (loading sections) on the holding member one by one. Through the setting of the bottom plate, several bolts to be injection-molded are grouped in advance. Then, when loading, the worker only needs to use the holding member to orderly clamp several groups of bolts to be injection-molded in the placement grooves into the injection mold one by one, so as to ensure that the injection work is more orderly and guarantee the production and processing efficiency of the bolts to be injection-molded.

[0010] In the above-mentioned fixture for batch transportation of bolts, positioning holes facing the same direction as each of the jacks are formed at both ends of the outer wall of the holding member close to both ends. Positioning grooves are formed at both ends of each group of the placement grooves on the bottom plate. When the two positioning holes and the two positioning grooves are in one-to-one correspondence, each of the loading sections and each of the placement grooves are in one-to-one correspondence. The user can install positioning pins in the positioning holes on the holding member. When clamping the bolts to be injection-molded in each group of placement grooves, the worker only needs to insert the two positioning pins into the two positioning grooves one by one to position both ends of the holding member, so that several jacks on the holding member are quickly aligned with several placement grooves in the same group, realizing the quick clamping of the bolts to be injection-molded.

[0011] Compared with the prior art, the fixture for batch transportation of bolts has the following advantages:

[0012] 1. By forming several spaced-apart jacks along the length direction on the outer wall of the holding member and installing magnets in the jacks, during the gap when the mold is performing injection work, the worker can pre-load the bolts to be injection-molded into each jack on the holding member. The magnetic suction of the magnets ensures the stable positioning of each bolt to be injection-molded. After the mold is opened and the parts are picked up, the worker can quickly load multiple bolts to be injection-molded into the cavity of the mold at one time through the holding member, so as to achieve the purpose of improving production efficiency. At the same time, it effectively avoids the situation that the worker accidentally touches the injection mold and being scalded by the residual heat, ensuring production safety.

[0013] 2. By providing a number of placement slots on the bottom plate in groups, during the gap between the injection molding operations of the mold, workers can pre-embed the bolts to be injection molded in all the placement slots of several groups. When the worker holds the holding member and aligns the loading sections of the jacks with the placement slots of each group, the bolts to be injection molded installed in several placement slots of the same group can be clamped together by the holding member under the action of magnetic force.

[0014] 3. The holding member and the bottom plate use two positioning holes and two positioning slots in cooperation with positioning pins to achieve the positioning of both ends of the holding member, ensuring that several jacks on the holding member can be quickly aligned with several placement slots of the same group.

[0021] The following are specific embodiments of the present invention and in combination with the drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0022] Such as Figures 1-4As shown, the tooling fixture for batch transportation of bolts includes a holding piece 1 and a base plate 2. The holding piece 1 is specifically in the shape of a long strip, and a plurality of sockets 11 are opened in the holding piece 1. The plurality of sockets 11 are arranged at intervals along the length direction of the holding piece 1, and each socket 11 is opened along the thickness direction of the holding piece 1 and passes through the outer walls of both sides of the holding piece 1, and each socket 11 is divided into an installation section 112 and a filling section 113 with an inner diameter smaller than the installation section 112 along the length, and an abutment edge 114 is formed between the installation section 112 and the filling section 113 in each socket 11, and a magnet 111 abutting against the abutment edge 114 is installed in the installation section 112 of each socket 11 by screwing or clamping, and the cross-sectional profile of the end port of the filling section 113 facing away from the installation section 112 along the length direction is arc-shaped.

[0023] Combine Figure 5 The bottom plate 2 is in the shape of a rectangular plate, and a plurality of placement grooves 21 are provided on the upper side surface of the bottom plate 2. The plurality of placement grooves 21 are divided into a plurality of groups. The plurality of placement grooves 21 in the same group are arranged at intervals along the length direction of the bottom plate 2, and the plurality of groups of placement grooves 21 are arranged at intervals along the width direction of the bottom plate 2. The shape of each placement groove 21 corresponds to the shape of the head of the bolt to be injection molded.

[0024] like Figures 3-5 As shown, positioning holes are respectively opened on the side walls of the gripping member 1 near both ends, and the orientation of each positioning hole is the same as that of the insertion hole 11 , and positioning grooves 22 are opened on the bottom plate 2 at both ends of each group of placement grooves 21 .

[0025] Working principle: Before operation, workers first install positioning pins in each positioning hole, and then can choose one person or more people to manually embed the bolts to be injected into each group of placement slots 21. When the injection mold is preheated, the worker lifts the gripping piece 1 so that the two positioning pins and the two positioning slots 22 on the base plate 2 are positioned relative to each other and inserted. Through the two-point positioning method, the loading section 113 ports of several sockets 11 on the gripping piece 1 are positioned one by one with any group of placement slots 21, so that the screws to be injected in each placement slot 21 are inserted into the loading section 113 of each socket 11 through the rod and are magnetically positioned by the magnet 111, and then The worker lifts the gripping piece 1 to transfer several bolts to be injected into the cavity of the mold. When each bolt to be injected is stuck in the cavity, the worker lifts the gripping piece 1, so that each bolt to be injected overcomes the magnetic force and escapes from the loading section 113, thereby completing the transfer of multiple bolts to be injected quickly and at one time, and avoiding contact between the worker's hands and the mold to prevent burns. In subsequent work, the worker can take advantage of the gap when the mold is being injected to pre-place the bolts to be injected in each group of placement slots 21. After the mold is opened, the subsequent mold only needs to use the gripping piece 1 to clamp the bolts to be injected in each group of placement slots 21 into the injection mold.

[0026] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains may make various modifications or supplements to the described specific embodiments or use similar means for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.

[0027] Although terms such as holding member 1, jack 11, magnet 111, mounting section 112, loading section 113, abutting edge 114, positioning hole 12, bottom plate 2, placement groove 21, positioning groove 22 are used more frequently herein, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present utility model; interpreting them as any additional limitation is contrary to the spirit of the present utility model.
